摘要： The present invention is a method and apparatus for performing neighborhood processing operations on an n dimensional processing plane. In a simple, two dimensional, example, an M by N processing plane is successively scanned by rows. The output information from each row is presented on column lines. The analog data resulting from a fixed number of successive scans are temporarily held in a multi-stage analog buffer. A computing array is configured to perform the neighborhood operations or other limited co-operand operations on the shifted data. The computing array examines information from a slice made up of selected numbers of successive rows of the entire array, performs the operations on that portion, and provides a series of output signals representative of the result. The analog buffer is pipelined; information from a new row represents only a single row of new data and the contents of the latch stage containing the oldest information is replaced with this new analog data, causing the information from the transducers of the oldest row to be lost. The operation is then performed on the new slice. This sequence is repeated until all representative slices of the total array have had the neighborhood operations performed on them.

摘要： A proximity sensor system includes a touch-sensor pad with a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed. A conductive paintbrush-type stylus is used to produce paint-like strokes on a display associated with the touch-sensor pad.

摘要： An integrated circuit amplifier having a random input offset voltage is adaptable such that the input offset voltage may be cancelled out. An input node is a floating input node and is coupled to a source of input signal by a first capacitor. A second capacitor is connected between the output of the amplifier and the floating node. An ultraviolet window above the second capacitor allows the floating node to be charged, by the application of ultraviolet light, to a voltage which effectively cancels the input offset voltage.

摘要： A moving object classifier is integrated onto a single integrated circuit chip and includes a retina comprising a two-dimensional array of photosensors upon which the image of the object of interest is focused. A position classifier receives inputs from the retina and determines where in the retina the image of an object is located. An object classifier receives inputs from the portion of interest of the retina and computes the degree of membership of the image to each class to be classified and determines which class has the largest membership function. A scan controller controlled by the position classifier limits the object classifier data to the portion of the retinal image which contains the object. An interface controller interfaces the other elements on the integrated circuit chip with a microcontroller, which comprises a standard CPU, memory and input/output lines interfacing to the interface controller.

摘要： A circuit for use as a channel of a minimum selector and subtractor circuit includes a P-Channel MOS transistor having a gate connected to an input node, a source connected to the output of a current source, and a drain connected to a fixed voltage source. The source of the P-Channel transistor is connectable to a common conductive line through a first switch. The source of the P-Channel transistor is also connected to the non-inverting input of a transconductance amplifier. The inverting input of the transconductance amplifier is connected to a first plate of a capacitor. The second plate of the capacitor is connected to a fixed voltage source such as ground. The output of the transconductance amplifier is connectable to its inverting input through a second switch. The output of the transconductance amplifier forms the output of the minimum selector and subtractor circuit. A plurality of individual channel circuits may all be connected to the common conductive line. The input nodes of the individual channel circuits are each individually connected to a different one of a plurality of analog input lines. The minimum selector and subtractor circuit determines the minimum analog value appearing on the plurality of lines and subtracts that value from the input values on all of the input lines. A maximum selector and subtractor circuit is formed by reversing transistor types.
