The invention relates to a scale system which employs a microcomputer forming an integral part of the analog to digital conversion means in which the microcomputer controls the sequence of operations for performing the conversion, accumulates and stores digital data derived during the conversion of the analog signal and combines and processes that data to provide the digital output data resulting from the conversion, all in addition to performing other scale functions. The invention relates to a...

A digital correlator compares two digital words a plurality of times. Each time the second digital word is shifted by one additional bit with respect to the first digital word. The results of the various comparisons are stored. The stored results are then searched to find the location of the results indicating the greatest similarity between the bits of the first and second digital words. This location is indicative of the number of bits by which the second digital word is displaced with respect...

A digital display clock including a one-minute indicating wheel, a ten-minute indicating wheel and an hour indicating wheel which are driven by intermittent and segmental rotations through separately provided Geneva-gear mechanisms for each individual indicating section, a driving system arranged in the back of digital clock, so that the clock is able to provide a wide and effective display area in front of the clock and an excellent design for a 24 hour display digital clock with diversity.

A system for converting an electrical signal to a number of pulses and counting those pulses to provide a digital signal related to the average of the original electrical signal. An accurate electronic clock is included to provide time information and to determine the period of measurement and of averaging. Digitized signal, average, and time information are displayed and provided for interfacing with other digital equipment. An output analog signal is derived alternately from the digitized inpu...

A digital speedometer is provided for use in an automotive vehicle and includes a transducer for connection to a conventional speedometer cable driver. The transducer is equipped with an optical encoder that produces electrical pulses in response to rotational motion of the speedometer cable driver. The electrical pulses are transmitted to a counting circuit which is reset by a variable reference oscillator. The frequency of the oscillator is much lower than the frequency of pulses from the tran...

A bearingless digital flowmeter consists of toroid-shaped cavity and of tangential inlet/outlet channels. A ball in the cavity revolves in proportion to the flow rate. The frequency of revolution of the ball is detected by photoelectric or magnetic pickup device. The flowmeter is linear even at small flow rates and measures flow in both directions. The inlet and outlet are on opposite sides of the toroid in opposed relationship, which not only improves accuracy, but permits the meter to register...

An apparatus for testing digital logic circuits without a computer and associated software employs a pseudorandom stream of input data to produce an unstructured output data stream which is analyzed by an efficient data collector and analyzer. Test signal generation is implemented by a pseudorandom number generator and a pseudorandom clock/reset generator while the resulting test data at the output terminals of the device under test is analyzed by a cycle redundancy code checker. Fault localizat...

A digital typesetter for imaging graphics quality characters of a specified font. The typesetter includes an electronic data processing system which receives first digital data defining the identity, form, size and placement of characters to be typeset; receives second digital data defining the contour of each character to be typeset with respect to a normalized encoding set of first and second coordinates; and produces third digital data defining the character boundaries intersecting a raster (...

The digital indicator measures surface deviations from a reference measurement point and employs a probe or plunger positionable against a part that is being measured such as a machine part. The device basically comprises, in addition to the probe or plunger, strain gage means, an amplifier for receiving signals from the strain gage means, a digital volt meter, a digital display, and a momentary setting swtich. A preliminary signal from the strain gages at an initial pressure level is coupled vi...
