Title: Direct digital measurement of DC voltage - using simple programmed sequence so enable direct reading by computer via MOS buffer amplifier
Inventor: PEPERSTRAETE J A
IPC: G01R19/255
Filed: 1986-01-20
Abstract: The d.c voltage to be measured is connected to a capacitor via a series resistor. At the start of a measuring cycle, the output of the digital measuring circuit is fed to a bidirectional buffer amplifier to discharge the capacitor. When the capacitor is discharged, the amplifier direction is changed and a digital counter is started. - The capacitor is charged by the voltage under test via the resistor, until the voltage across the capacitor has risen to a predetermined level. At this point, the amplifier stops the counter. The number stored in the counter is proportional to the d.c voltage of the source. (8pp Dwg.No.0/1)

Abstract: ABSTRACT OF THE DISCLOSURE             In an electrical multi-channel signal transmission system having channels with signal carriers of predetermined frequencies, each frequency is an integral multiple of a constant which is a measure of frequency spacing between channels with the addition or subtraction of an integral multiple of one or more other constants. The integral multiples of the one or more other constants are selected to cause the frequencies of significant intermodulation products produced by simultaneous treatment of carriers by electrical components, such as amplifiers, to be equal to other carrier frequencies. The frequencies are obtained from a plurality of oscillators with frequencies related to the constants.  The invention is especially useful whit cable television systems transmitting programs on low, mid and high band channels.     # 1089 P/2 CA

Abstract: ABSTRACT OF THE DISCLOSURE         A characteristic message exchange procedure is per-formed by a set of controller units at separate stations and of functionally identical design.  The combination of a con-troller unit and a utilization unit that characterizes the application of the station constitutes a complete station. Among other things, the controller units provide sequencing of the transmitting privilege among the stations one by one.  All message data are classified into four basic message models representing the applications of the stations.  The stations are interconnected by a single common transmission channel and the controllers are equipped to be sensitive to only four basic message models.  No central control unit is required for monitoring transmissions between stations.  All active stations receive all messages essentially simultaneously.  The channel may be a unidirectional wire  line looping the stations, in which case essentially simultaneous reception by all is provided by passing on the received signals, even at an addressed station, without intermediate storage and continued circulation is prevented only by blocking the received message at the station that is transmitting.

Abstract: OPTICAL READER CORRELATION CIRCUIT     Abstract of the Disclosure Bar codes imprinted or otherwise applied to an object are read and decoded by focusing light reflected from the code by means of an objective lens to an image intensifier tube.  Light energy reflected from the code impinges on the photo cathode of the image intensifier tube thereby causing an electron beam to generate a display on a phosphor screen with the electron beam deflected to center the code image on the phosphor screen.  A fiber optic array channels light from the phosphor screen to an array of zones of photo sensors each zone having an output coupled to a correlation circuit.          Output voltages from the correlation circuits are simultane-ously coupled to acquisition, tracking and reading logic.          Initially, upon detecting the presence of a code on an object, the acquisition and tracking logic responds thereto to produce deflection voltages to the image intensifier tube to provide centering on the phosphor screen.  Once centered, outputs from the correlation circuits are coupled to reading logic to generate an output waveform representative of the bar coded data.

Abstract: ELEVATOR TRAFFIC DEMAND DETECTOR            ABSTRACT OF THE DISCLOSURE         The detection of traffic demand for elevator cars serving a plurality of floors is related.  A device is provided for detecting the latest information on traffic demand based on the number of passengers actually boarding and alighting from cars (herein-after referred to as the "boarding and alighting passengers").  On the basis of the respective floors at which cars are stopped to serve, the direction of travel of the cars, and the number of passengers boarding and alighting from the cars at the respec-tive floors, the number of boarding and alighting passengers by direction is detected for each floor.          The detected numbers for the respective floors are totaled to detect the traffic demand at each floor by direction.  Further, the total is made for each traffic demand pattern to detect the traffic demand at each floor by traffic demand pattern and by direc-tion.  By taking the cumulative total of the totaled numbers of boarding and alighting passengers for all the floors by direction, the total number of boarding and alighting passengers is calculated.  The results of these calculations are used to detect various types of information on traffic demand.
