  • Patent number: 5412577
    Abstract: A control system is disclosed for controlling misregistration between the colors of an image printed on a web. The system includes an imaging device such as a camera or group of cameras, a processor, and image conversion circuits coupled to the processor. The system detects print color misregistration based upon the signals produced by the imaging device as a result of scanning the printed image. The conversation circuits convert the signals to signals usable by the processor to determine the color densities of the various colors within the image. These color densities are compared with reference color densities stored in a memory of the processor, where the reference color densities may be generated from a source such as the printing plates used to print the image for which misregistration is being monitored.

  • Patent number: 5377116
    Abstract: A method of designing a cutting tool uses finite element numerical models to predict a response of the tool during a simulated cutting operation on a workpiece, and to simulate a chip-flow phenomenon occurring during the cutting operation. The chip-flow model incorporates representations of a fracture mechanism describing a chip separation phenomenon, a heat-generating mechanism describing a thermal coupling phenomenon, and a shear localization mechanism describing a shearing phenomenon wherein these phenomena occur during the cutting operation. The predicted tool response and the chip-flow simulation are evaluated by an artificial intelligence system to render rule-based judgments which are embodied in recommendations for continuously modifying the models and input design variables until the simulation and response converge to an optimal result.

  • Patent number: 5365452
    Abstract: At least first and second adjacent parts supply tables of a parts supply apparatus are controlled so as to avoid unnecessary movement of a one of the parts supply tables not being used in successive parts supply operations, while at the same time, ensuring that the parts supply tables are sufficiently close to one another at the time of switching over between the parts supply tables to thereby reduce the duration of the switching operation. Alternately, the two parts supply tables are moved together from one position to another to maintain an interval therebetween which allows for a rapid switch-over between the parts supply tables when necessary. However, the rate at which the parts supply table in use is moved is greater than the rate at which the parts supply table not in use is moved, whereby the two parts supply tables come to a rest at different times to thereby reduce impact vibrations.

  • Patent number: 5363290
    Abstract: An improved irrigation controller of solid state design utilizes a microcomputer which retains and executes a watering schedule input by a user through data input means. One of the parameters of system operation is the times of day in which irrigation will start when the current day is selected to be active. The controller of this invention uses a slide potentiometer having multiple sliders which may be moved in a single slideway for setting multiple start times determined by the slider positions. In addition, a hot post terminal is provided in the controller connected to ground. This terminal can be used to determine station assignment by touching the station wires to the terminal as power is applied along a common line to the actuating devices, i.e. solenoids, of the various stations.

  • Patent number: 5359507
    Abstract: Disclosed herein is a sequence controller capable of executing programmable sequence operations written in its sequence table. The sequence table comprises a group of input condition collecting instructions, a group of branch condition collecting instructions, a table instruction and a group of input instructions, and has an accumulator for combining such instructions organically and selectively to deal with various sequence operation conditions. Thus it is possible to provide complicated control operations by use of the sequence table. The sequence table also contains a step number storing section which stores the original step number upon transition from one step to another, and a step return performing portion. When a predetermined branch condition is met, the step return performing portion initiates a return to the step stored in the section or to the step next thereto.

  • Patent number: 5359610
    Abstract: An encoding system encodes up to 64 kilobytes of data using a binary Bose-Chaudhuri-Hocquenghem (BCH) error detection code. The code has as a generator polynomial g(x):g(x)=(x.sup.20 +x.sup.17 +1)*(x+1)*(x.sup.20 +x.sup.3 +1)*(x.sup.20 +x.sup.3 +x.sup.2 +X+1)which in octal representation is:g(x)=4400001*3*4000011*4000017where * and + represent Galois Field multiplication and addition, respectively. The associated primitive polynomial is x.sup.20 +x.sup.17 +1. The encoder encodes the data using a code based on a polynomial f(x), which is g(x) multiplied by a factor, b(x)=x.sup.3 +x+1, or:f(x)=(x.sup.3 +x+1)*(x.sup.20 +x.sup.17 +1)*(x+1)*(x.sup.20 +x.sup.3 +1)*(x.sup.20 +x.sup.3 +x.sup.2 +X+1)which in octal representation is:f(x)=13*4400001*3*4000011*4000017The inclusion of the factor in the code enhances the code's burst detecting capabilities. The code is capable of detecting 7 random errors, and a single burst error of up to 64 bits or double burst errors of up to 24 bits each.

  • Patent number: 5359520
    Abstract: An adaptive control includes a digital error correction system (DECS) to reduce control system error to near zero by anticipating a problem and feeding forward in time a correction to deal with the problem before it happens. The adaptive control is used in a controlled system of the kind which is cyclical in operation and which operates in response to repetitive cycle commands so that the operation of the system is substantially predictable for a significant number of cycles of operation. The adaptive control is incorporated in a spatial chopping or scanning telescope system of the kind in which a telescope mirror is moved in repetitive cycle motions and in a rigidly prescribed pattern between varied orientations and wherein the mirror is held for a prescribed, relatively long period of time in each orientation and is moved rapidly in a relatively short period of time from one orientation to another.
