摘要： A low-friction, low-play bearing system for use in a carriage coupling drive system for a pen plotter including a moving carriage slidably mounted on a shaft between the ends of and carrying a U-shaped pen-carrying yoke in combination therewith for sliding motion along the shaft and rotary motion about the shaft. A pair of annular ball-bearing thrust bearings are disposed over the shaft between respective ends of the U-shaped yoke and the moving carriage. An annular bias spring such as a wave spring is disposed over the shaft between the moving carriage and one of the thrust bearings to create a longitudinal expansion force resisting play between the moving carriage and the U-shaped yoke.

摘要： A method and apparatus for routing, holding, and hiding cables associated with electronics devices. The preferred embodiment is an extrusion for application to a surface of an electronics device or incorporation into the framework thereof defining a groove capable of routing, holding, and hiding the electrical cable(s). The extrusion has a cross-section comprising a plurality of sides connected to one another to define a desired shape for the extrusion. A pair of the sides have a generally V-shaped orientation with respect to one another thereby forming a longitudinal slot in the extrusion capable of containing the cable therein. The slot-forming pair of sides each includes opposed portions comprising a plurality of adjacent V-shaped segments thereby forming opposed longitudinal teeth in the sidewalls of the slot capable of releasably gripping a cable disposed in the slot.

摘要： A system (34) for determining deviations in the state of motion of a projectile (10) from its intended state includes a comparison module (38) that receives the outputs S of a sensor array (36). The comparison module (38) converts the sensor outputs to a measurement vector Z.sub.m and computes the deviation of this measurement vector from an intended measurement vector Z.sub.0 received from a control system. The comparison module (38) then determines the difference E.sub.Z between this measured deviation and the deviation predicted by a Kalman filter (44, 46). In generating the measurement vector Z.sub.m from the outputs of the sensor array (36), the comparison module (38) "de-spins" the array outputs in accordance with the output of a phase reference (42), whose purpose is to indicate the phase with respect to gravity of the spin of the projectile (10) about its longitudinal axis. The Kalman filter's state-deviation estimator (46) weights the vector output of the comparison module (36) and adds it to the output of the Kalman filter's state-deviation predictor (44) to provide an updated state-deviation estimation E.sub.X (t:t), which the state-deviation predictor (44) then uses as a basis for its next cycle. The output of the comparison module (38) constitutes a measure of the performance of the state-deviation predictor (44) and is used as a correction factor for the phase reference (42) so that the system acts as a phase-locked loop to lock the phase reference (42) onto the projectile spin without the need for an external sensor to determine the direction of gravity.

摘要： An assembly for positioning a print head so as to transfer ink from an ink ribbon to a printing medium positioned on a movable platen adjacent to said ribbon supports the print head on a rocker member which enables the head to be swung between a print position wherein it engages the ink ribbon and a feed position wherein the head is spaced from the ribbon enabling ribbon to be moved. The rocker is rocked to move the head between its two positions by a rotary cam driven by a small low-power electric motor. When the cam engages the rocker member at selected angular positions, the head is maintained in its retracted feed position; otherwise, the head resides in its print position. The assembly also includes provision for detecting the angular position of the cam so as to produce signals to facilitate repositioning the cam and head promptly.

摘要： A method and apparatus for simulating a network comprising a plurality of processing elements useful in simulating, for example, complex digital combinatorial electronic logic circuits. Each type of digital logic element is assigned a symbol, and the symbols are stored in an array pattern in a memory, with the row and column addresses of the symbols in memory corresponding to their position in the network. The simulator sequentially retrieves each element in the network starting from an input and determines the element response to an input signal based on the type of element and the signals input to it. After all of the elements in the network have been processed, the simulated output of the network is available at the network output elements.

摘要： An optical element includes an ogival reflective surface which diverges an incident radiant energy beam substantially uniformly into a 2.pi. solid angle. The precise shape of the reflective surface is defined mathematically in relation to the desired solid angle of divergence and energy distribution of the incident beam. To facilitate mounting and alignment of the reflective surface in an optical system, it is formed internally of a body of optically transmissive material. The external surface of the transmissive body is shaped so as to provide normal incidence for rays reflected from the reflective surface. The element may be used as a beam diverger, or alternatively in reverse, to converge and collimate radiation.

摘要： The effects of impulse noise on the operation of a microprocessor-controlled Loran-C receiver are reduced by muting or attenuating the received signals in the front end of the receiver ahead of the receiver gain during a time period which preceeds the start time of the pulses being tracked. The attenuation is selectively removed after the start time of each pulse being tracked to permit the receiver to perform its time difference of pulse arrival measurements in the normal manner. The attenuation is also selectively removed during those time periods in which the receiver performs its envelope slope, skywave/groundwave and other such samplings. The attenuation is provided by a muting circuit which is controlled by a time gate signal that derives from the microprocessor of the receiver.

摘要： A precision microwave delay line fabricated using stripline techniques, but having features of a coaxial transmission line. The delay line is assembled from three pieces: a center board, an upper housing, and a lower housing. The center board is a nonconductive substrate with a stripline conductor. The stripline conductor defines a transmission path. The housings are made of conductive material. A channel is formed on the inner surface of each of the housings. The channels are arranged such that when the center board is sandwiched between the housings, the transmission path is contained within a uniform cross-section cavity formed by the channels. The housings are electrically connected to each other through the center board with plated-through holes at locations along the sides of the transmission path.
