EXHIBIT 3.22 WO2004/013833 PCT/US2003/024311 provided by CIRQUE CORPORATION. Multiple substrate layers and thus multiple or overlapping layers of electrodes generally results in a touchpad that is mostly transparent, but can be difficult to see 5 through. This becomes a problem of usability when the touchpad is disposed on the display screen. It is worth noting that attempts have been made to make the substrate layers and the inks used for electrical traces to be thinner and therefore to have 10 greater apparent transparency. The attempts so far have still resulted in a display screen that is uncomfortably dimmed by the touchpad electrodes. Accordingly, what is needed is a touchpad providing complete touchpad functionality that is more 15 transparent than those in the state of the art in order to provide greater viewing comfort to the user. BRIEF SUMMARY OF THE INVENTION It is an object of the present invention to 20 provide a touchpad that includes only one active electrode and one sense electrode on a single substrate, thereby improving display screen clarity by reducing the total number of electrodes used in the touchpad. 25 It is another object to provide the one active electrode in a plurality of different locations within the sensor area of the touchpad. It is another object to provide the one active electrode and the one sense electrode on a generally 30 transparent substrate. It is another object to provide the one active electrode and the one sense electrode as generally transparent ITO ink. 3 APLNDC00026865 WO2004/013833 PCT/US2003/024311 It is another object to provide the single-layer touchpad wherein the touchpad is capable of detecting an object touching a zone, and determining in which zone the object has been detected. 5 It is another object to provide the single-layer touchpad wherein the touchpad is capable of simultaneously detecting the presence of multiple objects touching a plurality of different zones of the touchpad. 10 It is another object to provide the single-layer touchpad wherein the one active and the sense electrodes of the touchpad are arranged in a desirable pattern, ,and wherein the desired pattern is made visible when viewing the display screen, but with 15 minimal interference. In a preferred embodiment, the present invention is a single-layer touchpad comprised of a relatively clear substrate, a first active electrode disposed thereon, and a sense electrode disposed thereon, 20 wherein the first active electrode and the sense electrode are comprised of a conductive material, wherein the first active electrode in combination with the sense electrode are used to detect the presence of a pointing object in a zone, determining in which zone 25 the pointing object has been detected, or the simultaneous presence of multiple pointing objects in multiple zones, and wherein the first active electrode and/or the sense electrode are made sufficiently visible so that a pattern is visually detectable to 30 the user when looking at the display screen. These and other objects, features, advantages and alternative aspects of the present invention will become apparent to those skilled in the art from a 4 APLNDC00026866 WO2004/013833 PCT/US2003/024311 consideration of the following detailed description taken in combination with the accompanying drawings. BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS 5 Figure 1 is a perspective view of a portable electronic appliance having a display screen and a clear touchpad disposed thereon to provide input. Figure 2 is an illustration of zones arranged as a column to provide scrolling input. 10 Figure 3 is an illustration of two parallel columns of zones for providing scrolling control for two different inputs. Figure 4 is an enlarged schematic diagram of the layout of electrodes for a clear touchpad that is made 15 in accordance with the principles of the present invention. Figure 5 is an enlarged schematic diagram of a different layout of electrodes for a clear touchpad. Figure 6 is an enlarged cross-sectional view of a 20 clear touchpad having mechanical dome switches disposed thereover. DETAILED DESCRIPTION OF THE INVENTION Reference will now be made to the drawings in 25 which the various elements of the present invention will be given numerical designations and in which the invention will be discussed so as to enable one skilled in the art to make and use the invention. It is to be understood that the following description is 30 only exemplary of the principles of the present invention, and should not be viewed as narrowing the claims which follow. When discussing features of touchpads, it was mentioned that cursor control is often a desired 5 APLNDC00026867 WO2004/013833 PCT/US2003/024311 function of complete functionality touchpads. Other desired functions include scrolling capabilities and navigation keys for moving through documents or controlling navigation through pages in a web browser. 5 However, these features are not always required in the particular device for which the touchpad is being used. Returning to the clear touchpad that was first described, the present invention provides touch zone 10 control in a capacitance sensitive limited functionality touchpad. Touch zone control is a useful feature wherein the clear touchpad of the present invention sends data to a device such as a portable electronic appliance having a display screen 15 as mentioned above. In figure 1, a clear touchpad 100 shown as various electrodes 102 is disposed over a display screen 104. The display screen 104 and clear touchpad 100 are part of a portable electronic appliance 106. 20 The portable electronic appliance can be any mentioned previously in this document, or any other type of device having a display screen that can take advantage of touchpad input. It is noted that the various electrodes 102 are shown without the detail of the 25 electrical connections required to make the clear touch pad functional. These electrical connections are shown in subsequent figures. Furthermore, the various electrodes 102 are shown as very dark lines on the display screen 104. 30 This exaggeration of the darkness of the various electrodes 102 is for illustration purposes only. It should be remembered that the inks or other conductive materials being used for the various electrodes 102 are relatively transparent to the user. 6 APLNDC00026868 WO2004/013833 PCT/US2003/024311 The clear touchpad 100 shown in figure 1 is also notable in that it defines distinct and separate zones as will be shown in greater detail. Data sent by sensing circuitry associated with the clear touchpad 5 100 indicates to the portable electronic appliance 106 the detection of contact by a pointing object. The pointing object can be a finger or other object that can be detected by a capacitance sensitive clear touchpad 100. 10 In addition, the clear touchpad 100 can also indicate in which zone the contact has occurred. Accordingly, the present invention provides the functionality of a one dimensional input device. For example, the clear touchpad 100 can provide the input of buttons. 15 Each separate is a single button. By detecting which zone or button has been touched, a distinct operation can be performed by the portable electronic appliance. Another example of a one dimensional input is a slide or scroll control. 20 Figure 2 illustrates that if the zones 108 are lined up to form a column, then movement from zone to zone can be detected as discrete steps. If more sophisticated touchpad circuitry is provided, then it may be possible to determine finer movement along the column, and thus provide smaller 25 incremental movement along the column. Furthermore, more than one column may be provided as shown in figure 3, so that multiple scrolling regions can be controlled by the same clear touchpad as demonstrated by columns 1 30 (110) and 2 (112), parallel clear touchpade, perpendicular clear touchpads, or some other arrangement of zones as may be desired. The pattern or layout of one dimensional regions or zones may be quite varied, and should not 7 APLNDC00026869 WO2004/013833 PCT/US2003/024311 be considered a limiting factor of the present invention. Figure 4 is an enlarged schematic layout of the presently preferred embodiment of the invention. 5 Figure 4 shows a single-layer substrate 10 which is assumed to be the plane of the figure. active electrode (X or Y) in a zone. 18. is needed to detect touching Assume that the electrodes 20, 22, 24, 26 are X electrodes. 10 Only a single Figure 4 has four zones 12, 14, 16, These four zones are defined only generally be the dotted lines that include each of the item numbers. The four zones 12, 14, 16, 18 are comprised of the corresponding electrodes 20, 22, 24, 26 and the space around them, out to the one sense electrode 30. 15 Notice that the sense electrode 30 is surrounded by a grounding ring 32 that shields the one sense electrode from signals on other electrode wires or other interference. The present invention operates when the active 20 electrodes 20, 22, 24, 26 and the one sense electrode 30 are coupled to a touchpad sensing circuit associated with the clear touchpad 10. The touchpad sensing circuit may be the circuit sold by Cirque ® Corporation in its touchpads. 25 It is noted that a touchpad sensing circuit that is designed for providing complete touchpad functionality can be used in a clear touchpad having a single layer. However, the touchpad sensing circuitry can also be modified to operate more efficiently without an input for an 30 active electrode that is not being used when only providing limited touchpad functionality. An important aspect of the present invention is to also provide the feature of shaping the active electrode, the one sense electrode, or both the active 8 APLNDC00026870 WO2004/013833 PCT/US2003/024311 and the one sense electrodes in desirable patterns. It was stated earlier that it is desirable to make the electrodes as transparent to the user as possible in order to avoid dimming a display screen. 5 However, it may be desirable to make at least a portion of the electrodes visible to a user when looking at the display screen. Thus, an important aspect of the invention is the ability to make visible a desirable pattern as seen 10 when looking at the display screen. Assuming that a single-layer touchpad has been disposed between the display screen and the user, or the touchpad is visible from the underside of the display screen, it may be desirable that the touchpad not be made 15 completely transparent to the user. For example, the electrodes of the touchpad can be made visible to the user by taking advantage of certain characteristics of the materials used in them. Consider a conductive material for the electrodes 20 whose width or thickness can be varied in order to obtain various degrees of visibility. Furthermore, additional materials may be added to the conductive material used for the electrodes, wherein the additional materials darken or lighten the appearance 25 of the conductive material. The purpose of increasing the opacity of the electrodes would seem to be contrary to the goal of making the presence of the clear touchpad unnoticeable. 30 However, making the electrodes at least partially visible in at least one zone enables a seller of a device to make a particular image visible to users of buyers of its product. In other words, the seller can brand the device so that there is no mistake as to the seller of the device when a logo or 9 APLNDC00026871 WO2004/013833 PCT/US2003/024311 other service or trademark is visually discernible to the user or buyer. Using the illustration of figure 4, assume that the logo of the seller is the shape of one of the 5 electrodes 20, 22, 24, or 26. One or all of these electrodes 20, 22, 24, 26 could be made slightly visible when looking at the display screen. The number of zones that can be provided by the clear touchpad can be modified as well, depending upon 10 the characteristics of the clear touchpad being used. The number of zones should not be considered a limiting factor, as the touchpad and its associated touchpad sensing circuitry can be modified to provide many distinct zones of desired. 15 Figure 5 is an enlarged schematic block diagram of another clear touchpad of the present invention. Note that the shape of the active electrodes 40, 42, 44, 46 are different from those of figure 4. This is simply to make it plain that the shape of the 20 electrodes can be modified to be many desirable shapes and patterns. Another important aspect of the invention is that the functionality of the clear touchpad can be combined with other mechanical features. 25 For example, one desirable mechanical feature might be a dome button. Figure 6 is an enlarged and cross-sectional illustration of this concept, wherein a touchpad substrate 50 is shown. The substrate 50 has disposed thereon a desired pattern or layout of electrodes 52 30 of the clear touchpad. Disposed over these electrodes are mechanical dome switches 54. The functionality provided by the electrodes 52 may be that of a scrolling region. The mechanical dome switches 54 would thus provide a different function in the same 10 APLNDC00026872 WO2004/013833 PCT/US2003/024311 space. However, the electrodes 52 might also function as buttons. area. Thus, there could be dual use of the same If the electrodes are active, then an electrode switch might be actuated. 5 If the electrodes are inactive, then the mechanical dome switches maybe actuated to provide a different input. It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. 10 Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention. The appended claims are intended to cover such modifications and arrangements. 15 11 APLNDC00026873 WO 2004/013833 PCT/US2003/024311 CLAIMS What is claimed is: 1.

The claims 1, 2, 4-13, 15-26 and 32-50 are pending. The examination results are as following. Claim Rejections - 35 USC § 103 2. The following is a quotation of 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. 3. Claims 13 and 47-50 are rejected under 35 U.S.C. 103(a) as being unpatentable over Hsu et al. (US 7,030,860) in view of Fujimoto (US 6,061,177). As to claim 13, Hsu disclose in fig. 5D, a display arrangement comprising: a display having a screen for displaying a graphical user interface (see abstract); and a transparent touch panel (transparent touch sensing, see abstract) allowing the screen to be viewed therethrough the sensor (see abstract) and capable of recognizing multiple touch events that occur at different locations on the touch panel (see finger position X/Y, that is different locations at X and Y) at a same time and to output this information to a host device to form a pixilated image (by X/Y positions); wherein the touch panel includes a multipoint sensing (X/Y positions, see abstract) arrangement configured to detect a change in capacitive coupling associate with those touch events (see col. 8, lines 38-41) and should be at distinct points across the touch panel. However, Hsu does not specifically disclose multipoint sensing configured to simultaneously detect and monitor the touch events. APLNDC00026891 Application/Control Number: 10/840,862 Page 3 Art Unit: 2629 Fujimoto discloses in fig. 1, a touch screen input device and method for use with a rearmounted video. The touch screen input device operates equally well in an environment with any level of ambient light or no ambient and can simultaneously detect multiple touches (see abstract, see col. 11, 7-16). It would have been obvious to one of ordinary skill in the art at the time the invention was made to implement the touch screen input device operates and can simultaneously detect multiple touches as taught by Fujimoto into display system comprising graphic user interface and multipoint sensing arranged of Hsu for producing the claimed invention because this would the coordinates of the remaining, approximately finger tip-sized, touches are sent to the computer operation system as touch inputs (see col. 11, lines 13-15). As to claims 47-50, Hsu et al. disclose further the display comprising multipoint sensing (coordinates X/Y) arrangement formed on single side of a substrate or on both sides of a single substrate (see col. 8, lines 1-21), and the transparent substrate is formed from glass (because transparent substrate always formed by glass for human eye can easily detect any systematic misalignment between the trace array patterns (see col. 8, lines 13-21). Allowable Subject Matter 4. Claims 1-2, 4-12, 32-45 are allowed. 5. Claims 24-26 and 46 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. APLNDC00026892 Application/Control Number: 10/840,862 Page 4 Art Unit: 2629 The following is a statement of reasons for the indication of allowable subject matter: None of the cited art teaches or suggests a touch panel having a transparent capacitive sensing medium, wherein the transparent capacitive sensing medium çomprises a transparent eleçtrode laver. the electrode layer inçluding a gurality_of electrically isolated electrodes and electrode traces formed from a transparent çonduçtive material, eaçh of the electrodes being placed at different locations in theJane of the touchlanel, çaçh of the eleçtrodes havinian individual traçe for operatively coupling to capacitive monitorinteirçuitry as claims 1 and 39; or a second layer spatiallX separated from the first layer and having a guralit of transparent geçoad conductive lines that are eleçtrically isolated from one another, the seçond çonduçtive lines being positioned transverse to the first conductive lines, the intergeçtion of transverse lines being positioned at different lgçations in the plane of the touch panel, eaçh of the second conductive lines being operativelv coupled to capacitiyç monitorinicirçuitry wherein the capacitive monitoring cirçuitry is çonfigured to deteçt çhanges in çharge coupling between the first conductive lines and the second conductive lines as claim 7; or wherein the multipoint sensine arrangement nrovides a oluralitv of transnarent canacitive sensine nodes that work independent of one another and that represent different points on the touch as claim 15; or a glass member disposed over the screen of the display; a transparent conductive layer disposed over the glass member, the conductive layer including a pixilated array of electrically isolated electrodes; a transparent cover sheet disposed over the electrode layer; and one or more sensor integrated circuits operatively coupled to the electrodes as claim 24; or a seçond transparent çonduçtiye layer disnosed over the second class member. the second transnarent conductive laver comorising a plurality_of spaced apart parallel lines having the same pitch and linewidths, the parallel lines of APLNDC00026893 Application/Control Number: 10/840,862 Page 5 Art Unit: 2629 the seçond transparent çonduçtiye layer beinLsubstantially perpendiçular to the parallel lines of the first transparent conductive laver: a third_glass membçr disposed eyer the sççond transparent çonduçtiye lay.er; and one or more sensor integrated çirçuits operatively.coupled to the lines as claim 25; or a yirtual_ground çharge amplifier coupled to the touchlanel for detectinghe touçh events on the touch panel as claim 46. Response to Arguments 6. Applicant's arguments with respect to claims 1-2, 4-13, 15-26 and 32-50 filed 2/20/09 have been considered but are moot in view of the new ground(s) of rejection.

(54) Title: A FLEXIBLE TRANSPanvis i TOUCH SENSING SYSTEM FOR ELECTRONIC DEVICES X INPUT PROCNESS NG - ARITHMETIC / L_ GESTURE Finger Presence i UNIT ~ Finger Pressure (57) Abstract: A transparent, capacitive sensing system particularly well suited for input to electronic devices is described. The sensing system can be used to emulate physical buttons or slider switches that are either displayed on an active display device or printed on an underlying surface. The capacitive sensor can further be used as an input device for a graphical user interface, especially if overlaid on top of an active display device like an LCD screen to sense finger position (X/Y position) and contact area (Z) over the display. In addition, the sensor can be made with flexible material for touch sensing on a three-dimensional surface. Because the sensor is substantially transparent. the underlying surface can be viewed through the sensor. This allows the underlying area to be used for alternative applications that may not necessarily be related to the sensing system. Examples include advertising, an additional user interface display, or apparatus such as a camera or a biometric security device. APLNDC00026921 WO01/027868 PCT/US00/27720 A FLEXIBLE TRANSPARENT TOUCH SENSING SYSTEM FOR ELECTRONIC DEVICES 5 BACKGROUND OF THE INVENTION Field of the Invention 10 The present invention relates to touch sensing transducers and systems. More particularly, the present invention relates to flexible and transparent object position recognition devices useful in applications such as cursor movement and user input for computing devices and other applications. 15 Description of the Related Field Touch sensing technology can be used to provide a variety of input to electronic devices, from emulating physical buttons or slider switches to more sophisticated recognition of patterns or gestures. For example, United States Patent No. 5,880,411 to Gillespie, which is hereby 20 incorporated in its entirety for its teaching of touch sensor technology, discloses a capacitive sensor trace array object position detector with edge motion feature and gesture recognition. United States Patent No. 5,305,017 to Gerpheide teaches an object position detector using capacitive sensing and is also incorporated in its entirety by reference for 25 its teaching of touch sensor technology. Another example of capacitive touchpads is United States Patent No. 5,543,588 to Bisset. However, in many applications it is desirable to display the surface underlying the touchpad. For example, the touchpad can be overlaid on an active display such as a LCD or CRT screen to facilitate input to a 30 graphical user interface (GUI). Alternatively, it may be desired to have SUBSTTE SHEET (RJLE 26) APLNDC00026922 WO01/027868 PCT/US00/27720 the underlying surface display static information such as a button pattern to guide user input or advertising. Neither Gillespie nor Bisset disclose or suggest the ability to display a surface underlying the touchpad sensor. The general strategy employed by the prior art to provide 5 transparent touch sensing technology for portable devices utilizes a resistive pad. A typical resistive pad consists of two substantially transparent substrates separated by a thin air gap, typically about 0.006 inches. One substrate is deformable, such as a polyester film, while the other is typically rigid, such as glass or polycarbonate plastic. Both 10 substrates are coated with a substantially transparent, conductive coating like Indium Tin Oxide on the surface where they face one another. On the ITO-coated surfaces, one substrate contains conductors at its left and right edges while the other substrate contains conductors at its top and bottom. To measure position in one axis, a voltage gradient is applied to 15 one set of conductors while voltage is measured on the other set. When an object deforms the resistive pad so that one substrate contacts the other, the point of contact will contain a voltage proportional to the distance from the conductor where the voltage was applied. To measure position in the other axis, the conductors for voltage application and 20 measurement are switched. There are other variations of the previously described 4 wire resistive pad sensors. One example is a 5-wire design which alternately applies an X-axis, than Y-axis voltage gradient to the one layer and then uses the second layer simply to sense voltage. 25 Different prior art techniques deal with the difficulty of maintaining a constant air gap between the two ITO layers and the stretching of the deformable substrate as it wears. For example, substantially transparent dielectric spacer dots, usually about 0.010" in diameter, can be arranged in a regular, grid-like fashion over one of the ITO surfaces. These dots 30 help maintain the air gap to prevent the two ITO layers from accidentally 2 SIESWUISHet ÇRE26) APLNDC00026923 WO01/027868 PCT/US00/27720 contacting. Further, the dots help counteract the decreasing performance of the deformable substrate as it wears and stretches. However, the use of these spacer dots generally reduces the resolution of the touchpad, as not all locations of such a resistive pad will necessarily generate a signal 5 when the two substrates come in contact. In addition to the resistive pad technologies, other examples of prior art include capacitance based technologies, stylus based technologies and pressure actuation technologies. Prior art capacitive touchpads such as United States Patent Nos. 5,457,289 to Huang and 10 4,806,709 and 4,733,222 to Evans suffer from various drawbacks of their own. For example, Huang requires frontal shielding for its capacitive touch sensor system and the Evans '709 requires a uniformly electrically conductive surface. Stylus based pads such as United States Patent Nos. 5,381,160 to Landmeir and 4,945,348 to Ibamoto require an 15 electromagnetic tool to provide input. Finally, pressure actuated touchpads such as United States Patent No. 4,484,038 to Dorman and 3,757,322 to Barkan have moving parts and thus suffer from drawbacks similar to the resistive pad technologies. 20 SUMMARY OF THE INVENTION The invention is a capacitive sensor system comprising a sensor trace and a processor configured to detect capacitance changes in the sensor trace to determine proximity of a conductive object. Preferably, the sensor trace is a part of a first plurality of sensor traces oriented in a 25 first direction and the processor detects capacitance changes in the sensor traces to determine proximity and positioning of the finger in the first dimension. More preferably, the system further comprises a second plurality of sensor traces oriented in a second dimension, wherein the processor is further configured to detect capacitance changes in the first 30 plurality of sensor traces and the second plurality of sensor traces to 3 MST~ñ SHEET ǾLE 26) APLNDC00026924 WO01/027868 PCT/US00/27720 determine proximity and positioning of the conductive object along the first and second dimensions. The preferred conductive object for this invention is a human finger, but a conductive stylus or other suitable device can be used as well. 5 To maximize transparency, the sensor system should have a uniform density of sensor traces. Thus, preferred configurations minimize the overlap of the first plurality and the second plurality of sensor traces. For example, each sensor trace may be configured as a series of diamond shapes aligned along a common axis. Accordingly, each plurality of 10 sensor traces thus creates a pattern of diamond shaped open spaces. By positioning the first plurality of sensor traces over the second plurality so that the diamond shaped sensor traces fall over the diamond shaped open spaces, the amount of overlap between the each plurality of sensor traces is minimized. Transparency is also maximized by utilizing materials 15 having similar indices of refraction. A primary object of this invention is a positioning system that uses a low-cost, highly integrated, low power, capacitive transparent sensor. This invention is suitable for many handheld electronic applications such as, but not limited to, cell phones, pagers, personal digital assistants, 20 remote controls, and computers. Non-handheld devices that require a positioning system with a thin transparent sensor are also appropriate for this invention. Preferably, the sensor system is equipped with a processor capable of recognizing gestures such as tapping or dragging to increase the flexibility of user input. 25 The current invention described offers a number of advantages over resistive pads and the other prior art technologies. First, this art is rugged. Its performance will not degrade over time and is not subject to mechanical wear and stress, being completely solid state and having no moving parts. Because this art does not rely on deforming a substrate, 30 the sensor can be activated with no actuation force. Second, the 4 S ESTITUTE SHEET ǾLE26) APLNDC00026925 WO01/027868 PCT/US00/27720 resolution of sensing is determined by the density of sensor traces and the precision of the A/D converters in the processor, not the physical properties of the materials as in resistive pads. Thus, very high positioning accuracy can be achieved. Because the current invention does 5 not require an air gap to be maintained between the sensing layers, positioning performance is hardly affected by mechanical damage or environmental conditions such as temperature, humidity or power supply voltage. Consequently, the positioning capabilities of this art require little to no user calibration. Furthermore, the lack of an air gap, with an index 10 of refraction much different than the substrate layers, allows this art to achieve greater transparency. Finally, the ability to use flexible substrate material to build the sensor facilitates the integration of this art onto devices that require a touch-sensing system on a curved, three- dimensional surface. 15 Alternatively, the sensor array itself can be directly applied to a rigid, curved three-dimensional surface without the requirement of a flexible substrate.

System 2 accurately determines the proximity and contact of 20 finger 4 or any other conductive object to the sensor 6. Capacitance changes induced by finger 4 on the sensor trace in the sensor 6 are digitized by the input processing block 8. The digitized values of capacitance values are processed by arithmetic unit 10 and then decoded by gesture unit 12 to determine if a finger was present. 25 Gesture unit 12 also processes input signals to determine the difference between constant finger contact and a finger tap. Blocks 8-12 may also incorporate methods to suppress electrical noise that may be sensed by sensor 6. Suitable means of implementing this sensor include the technologies described in United States Patent Nos. 5,880,411 and 30 5,305,017, which were incorporated in their entirety by reference thereto 6 suarrumsH (RJt.E26) APLNDC00026927 WO01/027868 PCT/US00/27720 above for these teachings. Other means of capacitive sensing technology known to those of skill in the art are also suitable. The sensor trace in sensor 6 must be designed so that the trace provides adequate capacitive coupling to the finger. In the preferred 5 embodiment, the sensor trace is a thin line of conductor that is drawn to the location where the finger is designed to contact. At this preferred contact area, the trace widens to a square or a circle approximately the dimensions of a typical fingerprint. This ensures that adequate capacitive coupling will occur between the sensor and the finger. Non-visible 10 portions of the sensor can optionally be drawn with an opaque conductor with better handling properties and lower resistance. Examples of an opaque conductor include, but are not limited to, silver ink and conductive carbon ink. Figure 2 is a cross sectional view of the preferred embodiment of 15 the capacitive sensor 6 (and also one-dimensional capacitive sensor 20 described below). A top transparent and electrically insulating substrate 52 is adhered with an optically transparent and electrically insulating adhesive 54 to another transparent, electrically insulating substrate 58 that is coated with a transparent conductor 56. Typically, the 20 substantially transparent conductor 56 is deposited onto the substrate 58 either by a sputtering process or by a printing method. The pattern of the transparent conductor trace 56 can be done by a photoresist and acidetch process. Alternatively, conductor 56 may be selectively coated, either by sputtering or printing, onto a negative pattern overlaying the 25 substrate 58. Then, removing the negative pattern leaves the appropriate transparent conductor trace pattern. Because sensor 6 only detects contact and proximity, only one sensor trace and one conductor layer is needed. Examples of transparent, electrically insulating substrates 52 and 30 58 include, but are in no way limited to, polyester film, glass, and 7 SUBSTITUTE SHI±l (RJLE 26) APLNDC00026928 WO01/027868 PCT/US00/27720 polycarbonate plastic. One example of a transparent, electrically insulating adhesive is 3M #8142. Examples of substantially transparent conductors include, but are not limited to, Indium Tin Oxide (ITO), transparent conductive plastic, and silver, gold, aluminum alloys. Those 5 skilled in the art will recognize that no material is completely transparent. To improve transparency of the sensor a number of techniques can be utilized. First, substrates 52 and 58 and adhesive 54 can be chosen to have similar indices of refraction. This improves transparency by minimizing the distorting effects of light traveling through materials of 10 different refraction indices. Second, employing the sensing art described U.S. Patent No. 5,880,411 allows the use of high impedance output drivers. Hence, the resistivity of transparent conductor layer 56 can be relatively high and still be usable with such a sensing system. A high resistivity such as, but not limited to, 300 R/square increases 15 transparency of the substantially transparent conductor layer 56. Layer 60 shows the location of an opaque substrate that would be viewable through transparent layers 52-58. Examples of such a substrate include, but are not limited to, a graphical display device such as, but not limited to a Liquid Crystal Display (LCD) or Cathode Ray Tube (CRT), 20 artwork, or additional electronics such a fingerprint recognizer. In some embodiments, layer 60 may be omitted altogether. Alternatively, substrate 58 can be omitted and transparent conductor 56 can be patterned directly on layer 60. In yet other alternative embodiments, layers 52-58 can be reversed 25 without loss of functionality. Furthermore, adhesive 54 can be eliminated so long as substrate 52 is electrically insulating and self-adhering to conductor 56. One example of a self-adhering, transparent, electrically insulating substrate is transparent-coat paint. Figure 3 shows a schematic representation of a one-dimensional 30 position sensing system 16. Such a system can detect not just finger 8 süßSTTUT SHtti (RULE 26) APLNDC00026929 WO01/027868 PCT/US00/27720 contact (like proximity sensing system 2), but also the location of a finger 4 or other conductive object along the direction of the sensor trace array. In Figure 3, sensor 20 contains a plurality of traces oriented along one direction, such as the Y axis, allowing sensing system 16 to determine 5 the position of finger 4 along that direction. Finger location is computed by measuring the capacitance of the traces and then computing finger position based on the increase in capacitance in traces covered or near the finger. Specifically, Y input processing block 22 measures trace capacitance simultaneously in all sensor traces, and digitizes the analog 10 capacitance values. These values are then converted to position and pressure information in arithmetic block 24. Next, position and pressure data are fed into a motion block 26 and gesture block 28. Motion block 26 computes finger motion along the trace array axis based on storing a successive history of finger position values. Gesture block 28 determines 15 if a finger is actually in contact with sensor 20 and whether the finger presence over a short period of time is considered a "tap". If a tap gesture is registered, the gesture unit suppresses the output of the motion unit. Blocks 22-28 also incorporate methods to suppress electrical noise that may be sensed by sensor 20. Suitable algorithms and means 20 for implementing this sensor include the technologies described in United States Patent Nos. 5,880,411 and 5,305,017, incorporated in their entirety by reference thereto as described above. Those skilled in the art will recognize that such algorithms are only illustrative and in no way limiting of the capacitive sensing technology that is possible with this 25 sensor. The one-dimensional sensor 20 is comprised of a plurality of sensor traces equally spaced along a given axis. To achieve adequate positional resolution, spacing of each sensor trace is typically designed so that a finger 4 covers at least two traces at any given location in the sensing 30 area to allow interpolation between the traces. A higher trace density or 9 SUB&T~vTE SH ÇO.E 26) APLNDC00026930 WO01/027868 PCT/US00/27720 higher precision A/D converters improves the resolution to which sensing system 1 6 can compute finger position. To maximize capacitive coupling between a trace and a finger, a trace is typically made as wide as possible (for example, slightly less than a trace spacing) without touching 5 neighboring traces. As described above with respect to the proximity sensing system 2, non-visible portions of the sensor can optionally be drawn with an opaque conductor. A cross-sectional view of one-dimensional position sensor 20 is shown in Figure 2, previously described. In the preferred, but not limiting 10 embodiment, the substrate 58 is uniformly coated with the transparent conductor and then the trace array is patterned using a photoresist and acid-etch process. Alternatively, a negative photoresist pattern can be screened on transparent substrate 62 and 68, the transparent conductor deposited using a sputtering or screening process and then the 15 photoresist pattern removed. As discussed above with respect to the proximity sensing system 2, the stack-up of one-dimensional position sensor 20 comprising layers 52-60 can be reversed and a self-adhering, insulative substrate 52 can obviate the need for adhesive 54. Figure 4 is a schematic representation of a two-dimensional 20 position sensing system 32. Such a system can determine finger presence as finger position along two direction axes. Finger 4 capacitively couples to sensor traces in sensor 36. X input processing block 38 and Y input processing block 40 measure capacitance values of sensor traces in the X and Y trace arrays and digitize the capacitance 25 values. Arithmetic unit 42 computes position and pressure coordinates based on the digitized capacitance values. Next position and pressure coordinates are fed into motion unit 44 and gesture unit 46. Motion unit 44 computes relative movement of the finger compared to the previous position of the finger. Gesture unit 46 determines the finger presence 30 over time and whether it constitutes a gesture such as a tap. If gesture 10 SUBSTITvl SHEET (RJLE 26) APLNDC00026931 WO01/027868 PCT/US00/27720 unit 46 recognizes a particular gesture, it will suppress the output of the motion unit 44. Blocks 38-46 also incorporate methods to suppress electrical noise that may be sensed by sensor 36. Suitable algorithms and means for implementing this sensor include the technologies 5 described in United States Patent Nos. 5,880,411 and 5,305,017, incorporated in their entirety by reference thereto as described above. Those skilled in the art will recognize that such algorithms are only illustrative and in no way limiting of the capacitive sensing technology that is possible with this sensor. 10 Figure 5A shows the preferred embodiment for the array of sensor traces used to compute position in the X-axis in sensor 36. Each trace 64 is a transparent conductor, equally spaced on a transparent, electrically insulating substrate 62. Each diamond 66 increases the trace area and also leaves a pattern of diamond-shaped regions containing no 15 conductive material. Figure 5B is the corresponding preferred embodiment for the array of sensor traces used to compute position in the Y-axis for sensor 36. Each trace 70 is also a transparent conductor, equally spaced on transparent, electrically insulating substrate 68. Diamonds such as diamond 72 increase trace area and leave a diamond20 shaped region where there is no conductive material. The actual number of sensor arrays and the presence of two axes of sensors will depend on the positioning area and resolution requirements of a particular device. To achieve adequate positional resolution, spacing of each sensor trace is typically designed so that a 25 finger 4 covers at least two traces in each axis at any given location in the sensing area. A higher trace density or more precise A/D converters improves the resolution that sensing system 32 can compute finger position. In some embodiments of the art, fewer X and Y traces will suffice to achieve the desired sensing resolution. Non-visible portions of 11 SUBSTB TE SHeel 00.E26) APLNDC00026932 WO01/027868 PCT/US00/27720 the sensor can optionally be drawn with an opaque conductor such as, but not limited to, silver ink. In the preferred, but not limiting embodiment, substrates 62 and 68 are uniformly coated with the transparent conductor and then 5 patterned using a photoresist and acid-etch process. Alternately, a negative photoresist pattern can be screened on transparent substrate 62 and 68, the transparent conductor deposited using a sputtering or screening process and then the photoresist pattern removed. Figure 5C is a top view of sensor 36 with Y-axis traces from 10 substrate 68 on top and X-axis traces from substrate 62 on the bottom. X-traces 66 are positioned so that their trace diamonds 72 fill diamond spaces between the Y axis traces 70. For illustrative purposes, Y-axis trace diamonds 72 are reduced in size to visually distinguish the diamonds in the two different arrays. In the preferred embodiment, these 15 diamonds are enlarged to the size of the spaces between X traces 66 so that sensor 36 appears to have a single uniform layer of transparent conductive material (except for the small regions where an X trace 64 overlaps a Y trace 70). Filling the entire active area with at least one layer of transparent conductor is desirable, but not limiting for the overall 20 transparency of sensor 36 since transparent conductive material such as (but not limited to) Indium Tin Oxide (ITO), gold, and silver are not perfectly transparent. Any region not covered with at least one layer of conductor in sensor 36 may be seen because it will have greater transmissivity compared to a region covered with a conductor. 25 Figure 5D shows a cross sectional view of the preferred embodiment of two-dimensional sensor 36. This stack-up can be reversed in order without loss of functionality. X-axis transparent, electrically insulating substrate 62 is the top surface that the finger or conductive object touches. The bottom side of the transparent, 30 electrically insulating substrate 62 is the transparent conductor traces 64. 12 8 BSTEL/TE SHEET(RULE26) APLNDC00026933 WO01/027868 PCT/US00/27720 A thin, transparent, preferably adhesive, insulator 74 separates X conductive traces 64 from Y conductive traces 70. Similar to X traces, Y conductive traces are coated on transparent, electrically insulating substrate 68. 5 Examples of transparent substrates 62 and 68, insulator 74, and conductive layers 64 and 70 have been described for Figure 2 and are equally applicable for the two-dimensional sensor. Similarly, the same techniques to improve transparency such as, but not limited to, matching indices of refraction among layers, and using a relatively thin layer of 10 transparent conductor, can also be applied to the two-dimensional sensor. Similar to Figure 2, layer 60 is an optional opaque layer that can be viewed through the transparent sensor. . In some embodiments, layer 60 may be omitted altogether. Alternatively, in some embodiments, substrate 68 can be omitted and transparent conductor 70 can be 15 patterned directly on layer 60. 13 80887 TUTE SHEET(ME26) APLNDC00026934 WO01/027868 PCT/US00/27720 A number of additional alternative embodiments of the invention are possible. For example, electrical shielding may be required to isolate sensor traces from electrical noise that arises from electrical circuits that are present below the sensor. One preferred, but not limiting 5 embodiment is shown in Figure 6 on two-dimensional sensor 36. Layers 62-68 are the same art as described in Figure 5D. Beneath transparent substrate 68, another layer of transparent insulator 74 attaches another layer of transparent conductor 78 and substrate 80. Unlike transparent conductor layers 64 and 70, transparent conductor 78 is a uniform layer 10 of conductor that is connected to an electrical ground. Grounding transparent conductor 78 provides sensor 36 with electrical shielding from electrical noise sources that might radiate from the opaque layer 60 or below. Examples of materials suitable for transparent conductor 78 and substrate 80 have already been described in Figure 2. 15 Adding a transparent ground plane using layers 74-80 can also be applied to the contact and one-dimensional sensor stack-ups shown in Figure 2 if such a layer were inserted between layers 58 and 60. In yet another embodiment, Figure 7 shows a two-dimensional transparent capacitive sensor 36. Transparent substrate 84 is adhered 20 using transparent insulator 74 to transparent conductor layer 64. Transparent conductor 64 contains the X trace pattern as shown in Figure 5A and is coated onto transparent substrate 86. On the other surface of transparent substrate 86, transparent conductor layer 70 contains Y trace array shown Figure 5B. Finally, transparent substrate 88 25 is adhered to transparent conductor 70 with transparent insulator 74. This particular embodiment, with substrate 86 coated on both sides with transparent conductor layers may allow for less error when aligning diamonds in the X trace array and the Y trace array. Because substrate 86 contains both conductor layers 64 and 70, the alignment of trace 30 arrays can occur prior to the etching/deposition of the trace arrays with 14 SUBSTTI TE SH = 00.E 26) APLNDC00026935 WO01/027868 PCT/US00/27720 the opaque photoresist pattern, greatly simplifying pattern alignment of X and Y traces. Proper alignment of the X and Y trace arrays is critical to the overall transparency of two-dimensional sensor 36 because the human eye can easily detect any systematic misalignment between the 5 trace array patterns. Examples of transparent, electrically insulating substrates 84,86, and 88 have been described in previous embodiments of two-dimensional sensor 36 and one-dimensional sensor 20. Additionally, for electrical shielding, transparent substrate 88 can be replaced with layers 78 and 80 10 as shown in Figure 6. This invention may also be adapted for use with a stylus in addition to the human finger. One method for doing so is to enlarge the contact area for a conductive stylus until its contact area is similar to that of a finger. This has the obvious disadvantage of the stylus needing to be 15 both conductive and the contact area needing to be large enough to capacitively couple to enough sensor traces. To reduce the contact area of the conductive input, one method is to increase the trace density so that even a fine, pointed conductive stylus can capacitively couple to at least two sensor traces. Alternatively, A/D converter precision can also 20 be increased to detect minute capacitance changes in sensor traces that result from a pointed stylus. One preferred alternative method that removes the restriction of a large contact area involves a resistive transparent coating applied to the top surface of the sensor array, resulting in the stack-up of layers shown 25 in Figure 8. For two-dimensional position sensor 92, the X and Y trace arrays are identical to that described in Figures 5A, 5B, and 5C. The stack-up of layers 62-68 is identical to that described in Figure 5D. Layer 94 is a rugged, resistive transparent coating that spreads the effective contact area of a pointed stylus, thus allowing a pointed stylus's 30 capacitive coupling to the sensor 92 to be similar to a conductive object 15 SUBST Tl TESHttI (ILLE26) APLNDC00026936 WO01/027868 PCT/US00/27720 with a larger contact area (such as a finger). Examples of such a layer 94 can be found, but are not limited to, those commonly used for electroluminescent lighting surfaces. Further details of such a sensing technology can be found in co-pending United States Patent Application 5 Serial No. 09/176,639. An approach for a two dimensional sensor that accepts any stylus input is to include a transparent, deformable layer sandwiched between the bottom sensor array layer and a ground plane. Figure 9 illustrates the stack up of a preferred but not limiting embodiment of such a sensor 92. 10 Layers 62-68 are the same as those described for a finger input twodimensional sensor 36 as described in Figures 5A-D. The only additional requirement for this art is that substrates 62 and 68 be flexible and deformable. An example of such a substrate is, but is not limited to, polyester film. 15 Beneath transparent substrate 68 is transparent insulator 74. This adheres to a transparent, deformable dielectric layer 96. Another layer of transparent insulator 74 adheres deformable layer 96 to a transparent, conductive layer 78 and transparent substrate 80. Transparent substrate 80 is typically made of a rigid material. Examples of such a transparent 20 rigid substrate include, but are not limited to, glass and polycarbonate plastic. Transparent conductive layer 78 is a uniform layer of transparent conductor that is electrically grounded. Functionally, a pointed stylus input will deform the X and Y sensors in layers 62-68 as well as layer 96, bringing the point of contact closer to 25 the ground plane. This deformation increases the capacitive coupling to ground for sensor traces near the point of contact. This capacitance increase is then detected by the sensing electronics. For finger input, capacitance is sensed by sensor layers 62-68 using traditional capacitive means. A detailed description of this art, though not in a transparent 16 SJBS7TUTE SHEET 3DŒ26) APLNDC00026937 WO01/027868 PCT/US00/27720 embodiment, can be found in U.S. Patent No. 5,942,733, which is hereby incorporated in its entirety by reference thereto. Yet another alternative method is to combine the transparent capacitive finger sensor of the present invention with a second 5 independent stylus input device. For example, a flexible transparent capacitive pad could be overlayed on a conventional resistive pad to provide superior finger sensitivity to that achievable with a resistive pad alone. Or, a transparent capacitive pad could be overlayed on a solid state sensor such as an inductive stylus sensor (e.g., U.S. Patent No. 10 4,848,496 to Murakami, hereby incorporated by reference thereto for this teaching) to produce a rugged sensor with high quality finger and stylus performance. The transparent position sensing system has a number of applications for portable electronic devices. Some examples (but not an 15 exhaustive list) of applications include: a) Pointing device for a touchscreen in a handheld electronic device. In the simplest implementation, a transparent two-dimensional capacitive sensor is affixed directly on top of a display device like an LCD screen to detect a finger's location on the display. The X-Y position of a 20 finger atop the sensor (and thus, the display) can then be fed to the device's main processing unit to control the user interface in the device. Such a user interface could include, but is not limited to, the control of a cursor on the screen, detection of taps for on-screen graphics that represent buttons, control of on-screen scroll bars, pull-down menu 25 selection, and stroke or gesture recognition for text-entry. b) Input device for a soft button array or scroll bar. In this application, the transparent sensor covers only the portion of the display device that is dedicated to displaying an array of buttons or a scroll bar. For a scroll bar application or a one-dimensional button array, the 30 transparent sensor would only contain a plurality of sensor traces in one 17 SUBSTITVISNtti ÇRE26) APLNDC00026938 WO01/027868 PCT/US00/27720 axis. By implementing the input device with a transparent sensor, the underlying graphics can change to suit the functionality required by the user interface c) Integration of input devices in a handheld electronic device. For 5 some handheld devices, one surface of the device may contain a display that requires a touch sensitive positioning system while another surface may require a button array. Because this art can be made from transparent, flexible material, the same capacitive sensor could be curved over the handheld device so that one portion of the sensor's trace arrays 10 covers the display surface while another portion of the sensor serves as the button array on another surface. This could reduce the cost of the handheld device by eliminating the need for additional mechanical contact switches. d) Transparent sensor for portable computer. The transparent 15 nature of the transparent two-dimensional position sensor allows the addition of apparatus for applications such as, but not limited to security and video to be designed into portable personal computers without consuming more real estate than a standard, opaque two-dimensional position sensor. In the case of security applications, the pointing nature 20 of the touchpad is a logical location to embed a fingerprint-based security system. Other biometric security systems such as a retinal scanner can also be placed underneath the transparent touchpad. The electronic sensor for the biometric system can be located underneath the sensor array (i.e. layer 60 in Figures 2 and 5D) and will be minimally affected by 25 the transparent sensor. Also, the transparent nature of the touchpad is also a reasonable location for a video camera since the touchpad surface protects the camera from the environment e) Graphic underlays beneath the transparent capacitive sensor (other than a display device). In some applications, the use of a display 30 device such as an LCD screen may not be necessary or cost-effective. In 18 SUBSTVISHet (RJLE26) APLNDC00026939
