Apparatus is disclosed for accumulating (counting) the occurrences of different types of events (such as trips travelled by an automobile) and storing these counts in substantially permanent form. The apparatus includes a logic element for determining both the occurrence of an event (trip travelled) and the type of event (length of trip), and a non-volatile memory such as a 'fusable-link' PROM or UV-erasable PROM, associated with and connected to the logic element, for accumulating and substantially permanently storing the statistical information.

Apparatus for accumulating and permanently storing statistical

Apparatus is disclosed which is capable of determining the two-dimensional connectivity profile of a prescribed binary variable associated with a surface. This apparatus comprises a 'connectivity-matrix' of switch cells and a two-dimensional sensory array of sensor cells. The sensor cells are responsive to the presence or absence of the binary variable and control corresponding ones of the switch cells in the connectivity matrix.

Apparatus for determining the two-dimensional connectivity of a

This invention is a two-dimensional pressure sensor which can be used to determine a pressure distribution across a two-dimensional object which comes in contact with the sensor. The sensor includes a light source, a matrix of light transmitting fiber endings which includes an alternate pattern of transmitting and receiving light fibers, a transmitting fiber sub-array located a distance from the matrix and composed of transmitting fibers, a receiving fiber sub-array located a distance from the matrix and composed of receiving fibers, a semi-transparent deformable medium located above the matrix, a retro-reflective material located on top of the deformable medium, a flexible membrane located adjacent said retro-reflective material and positioned to contact an object, and apparatus such as a photodetector array, for detecting light which is reflected by the retro-reflective material and transmitted to the receiving fiber sub-array.

Apparatus is disclosed for detecting the position of an object within a viewing field, such as a CRT display screen. The apparatus includes point sources of radiation arranged at spaced locations around the edge of the viewing field and a retro-reflective surface disposed around the perimeter of the viewing field. The retro-reflective surface reflects radiation received from its originating source back toward this source. A radiation receiver is arranged adjacent to each source to receive the radiation reflected back from the retro-reflective surface and to determine the angular position of an object within the viewing field which interrupts the path of radiation.

The sensor incorporates a sensing member which has a sensing surface for receiving a fingerprint and sensing means for sensing the ridges and valleys of the skin of the finger under investigation. The sensing member contains a multitude of small capacitors. When the finger is pressed against the sensing surface, the capacitances of the capacitors are locally changed in accordance with the ridges and valleys. The information about the capacitance distribution is transformed into an electric signal.
