摘要： A fabric touch sensor for providing positional information related to a touched region points. The improved electrographic touch sensor (10) is fabricated using at least one resistive fabric layer (12) in the form of conducting threads. This fabric is constructed using either unidirectional threads (16) or crossed threads (16. 18). The fabric (12) is separated from a second resistive layer (14) to prevent unintentional contact. In a preferred embodiment, both resistive layers are fabrics (12, 14) formed from conductive threads. Prevention of Moire-type visual patterns is achieved by orienting the threads in one fabric layer at an oblique angle to those of the second fabric layer. This sensor results in ease of fabrication, reduction of costs, reduction of parallax and eliminates substrate problems associated with those sensors employing the same. No preforming is required to adapt this sensor to a contoured object when both resistive layers are fabric.

摘要： A resistor electrode type touch sensor having enhanced area of linear response by reducing the bow in perimeters of the sensor and the method of accomplishing the same. A resistive coating is applied to one surface of a substrate. Within this coating orthogonal electrical fields are produced to give coordinates of a selected position. Overlying, but spaced from, the resistive coating is a flexible pick-off sheet having a conductive layer facing the resistive layer which will contact the resistive coating when the pick-off sheet is touched at a selected position. A resistance element is positioned proximate, but insulated from, the perimeter of the resistive coating. Electrodes of a selected effective size and spacing are located along selected paths proximate the edges of the resistive coating. Each electrode is attached to the resistive coating and connected to selected positions along the resistance element to provide selected voltages to the resistive coating. The effective size and spacing of the electrodes, and the positions of connection to the resistance element, are selected to produce an effective voltage gradient at the electrodes that progressively decreases from corners of the sensor to the center line of each edge of the sensor to counteract any voltage drop along the resistance element when voltage are applied thereto so as to substantially eliminate the bow of electrical fields produced in the resistive coating.

摘要： An electrographic touch sensor having Z-axis capability. In one embodiment, a uniform resistive coating (30) is applied to one surface of a substrate (12) and within this coating (30) orthogonal electrical fields are produced. Overlying the resistive coating is a flexible sheet (40) having a conductive layer, and interposed between the resistive coating and the conductive layer is an array of a material (32) having a substantially greater resistivity than that of the resistive coating (30). A Z-axis coordinate of a touched point on the sensor, related to the pressure force applied, can be obtained. This Z-axis coordinate is related to the change in the effective contact resistance between the resistive coating and the pick-off sheet caused by the pressure/force, and that change is "enhanced" by the high resistance array and thereby enables different values of pressure/force to be determined.

摘要： An electrographic touch sensor (10) having an increased proportion of area for providing linear output signals. The sensor utilizes a resistive layer (18) of a substantially uniform resistivity throughout. A resistance element (16) borders and is in contact with the resistive layer (18). Positioned along a selected path proximate the resistance element borders (16) are a plurality of insulator regions (26) having a selected effective length therebetween. These spaces, having the resistive layer therein, define resistive electrode elements (24) by which voltages are applied from the resistance element borders (16) into the resistive layer (18) whereby orthogonal electrical fields can be generated in the resistive layer. The effective length of the insulator regions (26) and the spaces are chosen to produce a voltage gradient along the path that substantially compensates for any voltage drop along the resistance element while orthogonal fields are being generated.
