Abstract: A communication device (140) for receiving and decoding a codeword of predetermined length, wherein the codeword includes information and parity bits, comprises a memory (315) for storing the codeword in the form of segments, wherein each segment comprises multiple bits forming bit combinations. A first look-up table (326, 327, 328, 329) included in the communication device (140) stores parity vectors corresponding to the bit combinations, and a second look-up table (325) stores values corresponding to syndrome vectors. A processing unit (310) coupled to the memory (315) and the first and second look-up tables (325-329) uses the bit combinations of the segments as indices into the first look-up table (326-329) to locate corresponding parity vectors, adds the corresponding parity vectors using modulo 2 arithmetic to form a resulting syndrome, and uses the resulting syndrome as an index into the second look-up table (325) to locate an erroneous bit included in the codeword.

Abstract: An improved method of automatic sawing employs a programmable automatic saw and a remotely located computer which provides additional control for the saw or a group of saws. The saw is equipped with a programmable controller that is capable of storing a series of jobs. The programmable controller allows an operator to run one saw job while contemporaneously programming another saw job. A third person, such an engineer or supervisor, may be programming an additional job or ranges of jobs for the saw while the operator is running and programming other jobs. The improved system provides control for a group of saws thereby assisting in the distribution of work flow, enabling efficient use of materials and improving inventory controls.

Abstract: A method of moving a cutter blade along a contour defined by a plurality of segments each connected end to end with one another and having at least one angle disposed between consecutively ordered segments calculates a distance from a corner point along one and another line segments and fits an arc to be followed by the blade between the line segments for eliminating repeated high force short time system inputs and replacing them with lower force longer duration inputs to affect the reduction and mechanical wear and the reduction of shocks to the system. The method further includes a process by which individual velocity profiles are determined for each contour in order to run the system at maximum velocity at all times during the course of a cutting operation.

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.

Abstract: A multi-lane controller providing redundancy comprises two lanes. Each lane comprises an input/output interface, a data flow controller and a control data processor. Each data flow controller receives input data from and supplies output data to both input/output interfaces. The information exchange between each lane does not rely on the proper operation of either the control data processor or data flow controller of any of the lanes.

Abstract: A safety operation system for a manipulator is provided with a first operation section. The first operation section has a first movable section, and outputs a first operation signal representing the position and angle of the first movable section. A failure detecting section detects failure of the first operation section on the basis of the first operation signal, and outputs a detection signal. When failure of the first operation section is not detected, a conversion section converts the first operation signal into a control signal. A second operation section has a second movable section which moves in accordance with movement of the first movable section, and outputs a second operation signal generated in accordance with movement of the second movable section. A comparison section compares the control signal with the second operation signal, and outputs a deviation signal used for opening the second movable section.

Abstract: A machining-error of a non-circular shape machining apparatus is corrected by controlling a movement of a tool which is synchronous with a rotation of a workpiece. A position of the tool is detected when the tool is according to a command position which is coincident with or close to a target position of the tool. At least an amplitude ratio and a phase difference of an amplitude ratio, a phase difference, and an offset difference between the target position and the detected position; is obtained. At least a process of increases and/or reducing the command position and a process of phase shift of the process for increasing and/or reducing the command position on the basis of the amplitude ratio, a process for shifting a phase on the basis of the phase difference, and a process for changing an offset of the command position on the basis of the offset difference are performed, whereby a first corrected command position is obtained.

Abstract: A compensator that enables an adaptive filter to be placed within a closed loop control system so as to reduce the effects of both measurable and unmeasurable disturbances on the output of the control loop. The disturbances may have spectra that lie within or outside the bandwidth of the control loop. The effectiveness of the reduction is dependent upon the capabilities of the loop actuator and/or the control electronics. The reduction is not limited only to the bandwidth of the control loop, as in conventional disturbance rejection, and is equally effective against feedback path disturbances which are unreduced in conventional approaches. A further aspect of the invention relates to a reduction of an intrinsic noise floor associated with control systems, including open loop and closed loop control systems, that does not require an independent noise measurement to be made.

Abstract: A method for moving with at least three degrees of freedom, particularly in theatre area on or below a stage, a complex three-dimensional structure, which is borne by several lifting machines or the like to be driven independently, is described. Three virtual parallel reference axes are installed in the space on which, as a function of one positioning signal in each case per point of application up or down movements are made. A virtual surface is drawn by these points of application. Several independent lifting machines or the like are installed above or below this surface. A weighting is determined for each lifting machine as a function of their position compared to each reference axis, which weighting is a measure of the amount by which the running of the relevant machine is influenced by the movement of the points of application on the reference axes. The movement and speed of movement of the points of application on the reference axes are predefined as positioning signals.

Abstract: In a device controlled by an original control signal for correcting a header error in an original STM signal comprising first through P-th header blocks and an HEC (header error check) block, each header block comprising first through N-th ATM cell header units, the HEC block comprising first through N-th ATM cell HEC units, a delay circuit (49) produces a delayed STM signal (S') by giving the original STM signal (S) a delay equal to (P.times.N) times an interval of each of the header and the HEC units. Another delay circuit (51) produces a delayed control signal (C') by giving the original control signal (C) the delay.
