Abstract: A touch pad for controlling electronic equipment includes a deformable touch surface and a compressible pad body in contact with the touch surface. The compressible body is formed from a material which scatters or diffuses light within the material. Multiple sources of light or other wave energy are directed into the interior of the substrate to form multiple illuminated cells inside the pad body. Each illuminated cell forms an integrated cavity within the pad body. A detector in communication with the compressible material detects light intensity within the integrated cavity. A processor receives signals from the detector and converts the signals into useable information relating to the position of regions of compression of the pad.

Abstract: The invention provides a bed occupant monitoring system comprising a pressure sensitive member attached to a support member for supporting a bed occupant, the pressure sensitive member comprising a plurality of pressure sensors. Each of the pressure sensors is configured to provide a reflected wave energy pressure signal by reflecting incident wave energy with an intensity which varies with a pressure applied to the sensor. A pair of fibres are coupled to each pressure sensor, each pair of fibres comprising an input fibre and an output fibre. The fibres are coupled to interface electronics comprising a wave energy source coupled to the input fibre of each of the pairs of fibres for providing the applied light energy, and, a wave energy detector coupled to the output fibre of each of the pairs of fibres for converting the scattered light energy into an electrical signal.

Abstract: A method for verifying the identity of a person comprises providing a plurality of pressure transducers and deriving a key from pressures measured by the pressure transducers when a person presses a hand (or other body part) against the pressure transducers. The key can be compared to a previously stored reference key. Apparatus for verifying the identity of a person may have an array of pressure transducers coupled to a controller. The controller produces the key and compares it to a reference key.

Abstract: An input device has a flexible surface on which are formed deflection sensors. The flexible surface can be deformed against an adjacent resilient layer. The deflection sensors detect the deflection of the surface. Electronic circuits for processing signals from the deflection sensors to yield information regarding the locations and magnitudes of forces deflecting the surface may be deposited all, or in part on the flexible surface. The input device may be combined with a display to yield a touch-sensitive display suitable for use in a wide range of applications.
