A fabrication arrangement using plural LSI chips to make a bit stream detection system requiring a programmable logic array which is too large to fit on a single LSI chip. Due to the small number of input/output pins available on any LSI chip, the fabrication arrangement divides among the chips an input shift register, the array, and array input latches. Each LSI chip also has time-multiplexed array outputs and time-multiplexed feedback inputs that minimize the pins and enable interconnection am...

A system for measuring the accuracy of an internal timing source of a device having a light emitting display which is energized at a rate derived from the timing cycle of that timing source includes an optical pickup disposed for receiving light emission from one element of the display and generating a signal having the same frequency as the frequency of such light emission. In one embodiment, the pulses of that signal which occur within a given time period are counted and the number of such cou...

An improved image dissector camera tube system for improving the signal-to-noise ratio in which the aperture plate of the image dissector has a plurality of apertures, the apertures individually biased by an electronic control network to accomplish a Hadamard encoding of the electron image.

A data processing system is disclosed for selecting the correct form of a garbled input word misread by an optical character reader so as to change the number of characters in the word by character splitting or concatenation. Dictionary words are stored in the system, having characters which are flagged for segmentation or concatenation OCR misread propensity. The OCR word and a dictionary word are loaded into a pair of associated shift registers, aligning their letters on one end. The dictionar...

A system is disclosed for determining and recording a plurality of individual rates of occurrence of predetermined events over a time span wherein the system utilizes a sensor-accumulator which senses the occurrence of a plurality of events over a predetermined time and translates the accumulated total into a binary expression. The binary expressions are periodically written into a dynamic recirculated memory in a serial fashion and after a predetermined time are all read out to a printing devic...

A pattern preliminary processing system wherein high and low frequency noise other than the pattern signal from a pick-up tube are eliminated by a filtering circuit thereby to "relieve" the pattern against the background and the thus obtained pattern signal is tri-valued into signals of high, medium and low levels by means of a processing circuit having two different threshold values, and then the signal of the medium level is converted into a signal of high or low level with reference to periph...

A multi-channel multi-genre character recognition discriminator is disclosed which performs the decision making process between strings of characters coming from a multi-channel (i.e., three or more channels) alpha-numeric output optical character reader (OCR) system for use in such applications as, for example, text processing and mail processing. The multi-channel output OCR uses separate recognition processes for each genre or character set indicative of a distinct group with respect to style...

Improved features for a fabrication arrangement that reduces the number of LSI chips required in a bit stream measurement system comprised of a plurality of measurement elements, each element including a large programmable array. The improvements are on the basic fabrication arrangement of patent application Ser. No. 482,824. The improvements relate the chip and measurement element fabrication to the detection significance of parts of the bit stream by substituting delay shift registers for arra...

An adaptive imaging system is described incorporating: a two-dimensional electro-optical detector array with as many as one hundred million detectors; a time-sharing multiplexer which samples each preamplified detector signal; an A/D converter and digital filter; and a computer which generates adaptive control signals to the rest of the system according to criteria observed and recognized by the system. Coupling conductors between detectors and their respective amplifiers are three-dimensionally...

The invention relates to a method for the automatic recognition of characters, preferably of figures, which may be hand-written on an information carrier provided with an arrangement of demarcated rectangles- one for each character. These handwritten characters are projected on to a matrix, where a camera tube ensures the scanning of the matrix, and the information thus read is recorded in a store and subsequently handled by a processor. A device for carrying out this method comprises a characte...
