Abstract: A noncanonic fully systolic least mean squares adaptive filter architecture encompasses both tap weight updates and filtering and allows cascadability without penalties in speed or accuracy. A systolic tap weight update section is followed by a systolic FIR filter section. An array control and alignment section and a forward loading shift register provides a modified coefficient update circuit which facilitates the interface between the two sections. This architecture allows for efficient microprocessor control of the filter algorithm.

The control device for weft inserting is constructed by inferring a corrected value of at least one parameter for weft inserting by fuzzy inference on the basis of at least one operating information relating to the weft inserting in a weaving machine in order to accept an operating condition of the weaving machine at an objective value, and controlling at least one actuator for weft inserting on the basis of the corrected value inferred by the fuzzy inference.

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.

Conveyor transports are adjacent the conveyor rack assemblies for transferring objects between the conveyor rack assembly and the runner transports.

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.

Abstract: An apparatus ideally suited for the small mailing service is disclosed. The apparatus can take pro-printed, un-addressed mail pieces of non-identical size delivered to the mailing service from different merchants and combine the mail pieces to create mailing bundles at the lowest postal rate and group the bundles to create a single mailing. In the apparatus a computer serves to take the merchant mailing lists, merge and sort the entries thereon into lowest postal rate groupings, and use this merged data base to enable a sequence controller and associated machinery to physically commingle and address the non-identical mail pieces into the single mailing bundle. Provision is also made for generating required postal service documentation and invoices from the mailing service to the merchants.

Abstract: A method of programming a programmable controller in a manner by which a variety of menus, options, or questions seeking limited parameter answers are presented to the user; for example, setup parameters such as the type of labware, source and destination of reagent transfer etc. for conducting a particular biological and chemical assay experiments by an automated laboratory workstation. Software "templates" are used to focus the request for parameters from the user to tailor user needs to the laboratory workstation's capabilities. The software templates are designed to accommodate a wide variety of experimental setups in accordance with the setup parameters input by the user. By providing the parameters with the assistance of the templates, the user may program a complete set of instructions for conducting a biological or chemical assay. The instructions may include the time and method for undertaking the experiment.

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.

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.

Abstract: Through a localized compact workstation (104), the operator is offered all the monitoring, alarming and control functions which have been previously dispersed over many control panels located throughout the control room (100). The information display hierarchy is composed of an IPSO overview display (122), video display units (108) preferably based on CRT technology and qualified video display units (116) preferably based on solid state flat panel display technology. Associated with each display unit is an individual, independent control module to allow process and component control. One control module (112) supports non-safety control functions and avoids separate controllers for components and process control. Another control module (118) is a qualified system which supports safety system control functions and avoids separate controllers for component and process control.

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.

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.

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.

Abstract: The present invention includes processing circuitry (11) interfacing with a multi-process environment (10) for performing a method of determining an average batch size. A processor (12) receives input parameters corresponding to characteristics of the multi-process environment (10) from interfacing circuitry (18). These input parameters generate a first utilization factor which generates a first estimate of the average batch size during a first iteration step. A second utilization factor and in turn a second estimate of the average batch size are generated during a second iteration step.

Abstract: Parallel-working controllers are provided to control processes whose performance is dependent upon working points. These controllers are allocated to selected working points, and their output signals are put into effect, after being weighted, in dependence upon the working-point parameters that have a dominant influence on the process performance. The method is preferably implemented using fuzzy logic. A transition which is smooth in terms of interpolation is possible among the controllers.

Abstract: A method and apparatus are disclosed for inherent, reliable control of real time systems. The technique is based on asynchronously scheduling a plurality of sensor sampling cycles over a suitable sampling interval. The corresponding plurality of sampling signals so obtained are temporally redundant and out of phase with respect to one another. This plurality of sampling signals is processed by a corresponding plurality of controllers. Thereafter, a multiplexor means is used to alternately and asynchronously receive from each controller a subinterval portion of each of the plurality of signals corresponding to each of the plurality of controllers. In this way the sampling interval is responsively partitioned into subintervals wherein each controller of the plurality effectively controls the system for each respective subinterval. Concurrent multiple control of each interval inherently masks and compensates for faults or failures.
