Abstract: A touch sensor for sensing user input comprising one or more elements. At least a portion of one or more of the elements is configured to be desensitized, in order to determine the location of one or more user inputs.

Abstract: The disclosure relates to a touch pad and a corresponding touch position determining unit (TPDU). The touch pad comprises a plurality of sensing elements that each extend in a first direction and are displaced from one another in a second direction, wherein the plurality of sensing elements is provided in a single layer. The TPDU comprises a sensing element configured to present an electrical property associated with one or more touch properties of one or more fingers along a length of the sensing element, the TPDU configured to: set an attenuation setting to a plurality of different attenuation settings; generate a plurality of touch signals, wherein each of the plurality of touch signals is generated in accordance with the electrical property at a different attenuation setting; and determine the one or more touch properties using the plurality of touch signals.

Abstract: A touchpad is formed of an electrically insulating membrane (10) with a first series of spaced apart conductors (12) on a first face of membrane (10) and a second series of spaced apart conductors (14) on or proximal thereto, in which there is no electrical contact between the first and second series of conductors (12, 14) Each conductor in the first and second series of conductors is sensitive to the proximity of a finger to modify the capacitance of the proximate conductor to detect the presence of the finger positioned close to that conductor. A scanning system operative to sample one of the conductors in turn from both the first and second series of conductors (12, 14) in order to measure and store a capacitance value associated with that respective conductor. The scanning system is operative to maintain all conductors (12-n, 14-n) at a common potential equal to the potential of the conductor being sampled when the remaining conductors are not actively being sampled by the scanning system.

Abstract: A touchpad, which may include a keypad array, digitizing tablet, touch screen or an electronic mouse, is operable through a suitable dielectric medium, operating by capacitive effect and suitable for use as a computer interface in conjunction with a monitor screen, or as a computer input device in a number of applications, for example, as a cash till keypad.
