摘要： A touch-responsive circuit uses an ohmic contact connected via a dc blocking capacitor to the high impedance input of an amplifier. A controllable impedance element shunts the capacitor and amplifier input. When the element is in the high impedance state, a weak voltage induced by touching the ohmic contact causes the amplifier to produce an output signal indicative of such touching. Touch response is disabled when the element is in the low impedance state. Advantageously, the controllable impedance element comprises a series-connected pair of diodes that are selectively forward or reverse biased; the element also may comprise an active electronic device such as a transistor.A data input terminal employs a matrix of ohmic contacts each having an associated touch-responsive circuit. Column scanning is accomplished by conditioning the controllable impedance elements in all but a selected one column to the low impedance state so that touch response is enabled only in that one selected column. The ohmic contacts in each row are connected to a common amplifier for that row. A priority encoder provides an encoded signal designating which amplifier produces a touching-indicative signal, and hence designating which row in the enabled column contains the touched ohmic contact.

摘要： A capacitively coupled tablet for use with an electrically conductive pen comprises segments each including at least one lattice point of a matrix which comprises groups of spaced conductors which are disposed along coordinate axes. The segments are mutually electrically isolated by an electrically conductive shield layer having apertures which correspond to the surface area of the respective segments, and are marked with corresponding characters to serve as keys. An electrically insulating layer is disposed between the shield layer and the groups of conductors, and a similar surface layer is disposed on the shield layer.

摘要： Each of the inputs of an analog multiplexer are connected to a plurality of capacitive keyswitches and a reference capacitor. At the first multiplexer scan position, the reference capacitor is charged through a charging resistor and when a predetermined voltage is reached a threshold amplifier is caused to respond. The time period required to charge the reference capacitor is stored and compared with the time period required to charge each of the keyswitches. A control signal is generated in response to this comparison providing a signal representative of the capacitive value of the keyswitch in relation to the reference capacitor and thus the operative condition of the keyswitch.

摘要： Keyboard switching arrangements have been described that employ a plurality of independent back electrodes, supported at defined touch locations, and a single sheet of foil electret material supported in close proximity to the back electrodes. As the foil is subjected to a tactile force at one of the touch locations, it is displaced to generate a signal in a circuit connected to the electrode associated exclusively with that touch location.

摘要： A n-key capacitive keyboard is coupled to an n-bit shift register. Each key is sequentially ''''interrogated'''' and, if actuated, an output pulse appears which is applied to the input of the shift register. The output pulse is also compared to the output of the shift register, corresponding to the ''''state'''' of the key in the prior cycle. An output pulse is generated on the first occurrence of a signal representing actuation of the key. The output of the shift register is also applied to make the key circuit more sensitive and therefore require less key travel to pass the interrogating pulse.
摘要翻译： n键电容式键盘耦合到n位移位寄存器。每个键顺序地“询问”，并且如果被启动，则出现输出脉冲，其被施加到移位寄存器的输入。输出脉冲也与移位寄存器的输出进行比较，对应于前一周期中的键的“状态”。在表示键的启动的信号的第一次出现时产生输出脉冲。移位寄存器的输出也被应用于使键电路更加敏感，因此需要较少的键行程来通过询问脉冲。

摘要： A system for identifying a particular position on the face of a display device by simply touching the area with the finger. The area is a conductive pad connected to a relaxation oscillator whose frequency is lowered by the touch. The oscillator is therefore identifiable and a digital computer is enabled to perform a prescribed act such as new information transferred to the display device, dependent upon the location of the area touched.
