Abstract: A method for synchronizing common values in a distri­buted system, at least one node of which is a cyclic, rule-based, object-sensitive production system. Values altered in one part of the system are implicitly rather than explicitly communicated and processed to and from the rule-based node. All communications to the rule-based node of common values changed by the nonrule-based nodes are by way of a list independent of and concurrently with any procedural request of the rule-based node, there being no necessary relation between the list contents and the proce­dural request.

Abstract: Disclosed is a unit for attenuating frequency components generated in a sideband of a frequency of an AC voltage applied to an electro-mechanical energy conversion element. This attenuation is achieved by modulation performed in a speed control apparatus for a vibration driven motor. The control apparatus includes a filter for cutting frequency components of a smaller frequency difference (fd) or more of an absolute value of a frequency difference between a natural frequency of an n-th order vibration and a natural frequency of an (n-1)th- or (n+1)th-order. A filter output is input to a modulator in a driving circuit, and noise of the vibration driven motor can be greatly reduced.

Abstract: A half-bridge is made insensitive to transient induced common mode currents in a pair of control lines between a level shifter and a floating driver for a power transistor of the half-bridge by the provision in the receiver portion of the floating driver of a double differential amplifier responsive to the difference between the voltages developed across sense resistors in series with the control lines. The amplifier produces a pair of output voltages for selectively setting and resetting a flip-flop which controls the conductive state of the driven power transistor. The double differential amplifier has an inherent central dead zone, providing noise immunity, and optional clamp means to limit the extremes of the voltages developed across the sense resistors. The transmitter portion of the level shifter contains elements thermally and resistively matched to the receiver for determining the amplitudes of the transmitted control currents.

Abstract: A circuit is tested for unwanted shorts and opens by positioning the circuit (14) between a pair of electrodes (26, 32) in a chamber filled with an inert gas with the circuit conductors facing one of the electrodes. The circuit is charged by applying a selected voltage to the electrodes to produce an electric field extending generally perpendicular to the circuit, the voltage polarity being such that the one electrode (32) carries the negative electrical charge. The circuit is then subjected to a pulsed laser beam brought to a focus between the one electrode and a selected spot on a conductor of the circuit so as to ionize the chamber gas at the beam focus to form a plasma so that an electric charge is imparted to that spot and to other circuit conductor portions having electrical continuity with that spot. The circuit is then discharged by reversing the polarity of the applied voltage and increasing the voltage magnitude substantially to the breakdown voltage of the chamber gas so as to form a glowing discharge plasma in the chamber gas opposite the charged portions of the circuit conductors. The circuit is observed to determine which portions of its conductors are glowing and therefore have electrical   continuity with the selected conductor spot and which portions are not.

Abstract: The disclosure relates to a closure system for a film wall package including profile strips (2,4) having a reclosable seal (6,8) of the interlocking type, flange elements (10,12) and, adjacent the reclosable seal, an adhered strip of peelable material (22,24). The peelable material (22,24) and the profile strip (2,4) may be co-extruded. With packaging film attached to the profile strips, typically to the flange elements, the resulting product may be used in a horizontal form, fill and seal operation, at which time the reclosable elements are mated and a peel seal is formed. The peel seal may be disposed on either side of the reclosable seal with respect to the interior of the package. The benefits of both peel seals and reclosable seals may be obtained by using optimum materials for those elements while, at the same time, allowing the use of a different material for the walls of the package.

Abstract: A fault tolerant sequential memory includes primary and redundant memory rows (or columns) and primary and redundant shift registers. The redundant memory rows (or columns) and redundant shift registers are formed at the end of the serial chain. Each shift register of each primary and redundant memory block is interconnected with an independent, separately programmable multiplexer logic circuit. Each multiplexer logic circuit includes an independently programmable repair buffer for logically bypassing a defective primary memory block and associated shift registers within the primary memory array. Each redundant memory block includes a multiplexer logic circuit having an independently programmable repair buffer for logically enabling a redundant memory block and shift register at the end of the serial chain. Consequently, a faulty memory block, including its shift register and memory row (or column) is bypassed and is effectively removed from the shifting sequence. The redundant memory block, including a redundant shift register and a redundant row (or column), is inserted at the end of the shift register chain by opening a programmable fuse element.
