摘要： A current mode subscriber line interface circuit (SLIC) for telephone system in which AC and De impedances for tip and ring connections of the SLIC are separately set. A DC filter separates the DC and AC components of tip and ring currents, and a current amplifier amplifies the AC components separately from the DC components. A pair of resistors set the AC impedance value, and also may be used to set SLIC four-wire to two-wire gain separately from SLIC two-wire to four-wire gain.

摘要： A splined radial panel solar collector structure approximates compound curvature surfaces by a three-dimensional arrangement of compactly stowable flat reflective panel segments mounted on a collapsible, space-deployable support structure of linear components. The support framework is formed of an umbrella-like framework of radially-extending ribs, struts and cords which deploy away from a central hub to form a system of radial trusses. A semirigid reflective surface structure is divided into sections of radial panels which are supported and shaped by an arrangement of radially tensioned flexible tape members aligned with the ribs. Connecting ties between the tapes and the ribs cause the tapes to assume a catenary curve. The ribs and flexible tape members are bridged circumferentially by sets of cords and ties to which the panels are joined. These cord and tie pairs place the panels in bending to effect a "splined" approximation of a parabola in the radial direction. The panels are arranged in a side-by-side relationship so as to be foldable in the circumferential direction during stowage. The panels are also discontinuous in the radial direction along lines connecting adjacent rib hinges in order to allow the reflective surface to be folded at the hinge points during stowage. As a result, each gore is effectively subdivided into a number of radial sections determined by the number of hinges along each rib and associated tape member. Openings are provided between the ends and sides of the panel strips so as to permit relative movement during folding and deployment, and to allow the panels to expand and contract with temperature change.

摘要： A linear force actuator system for stabilizing a support structure employs a linear dc motor whose primary winding is driven by a pulse width modulation control signal representative of a force input, through which the secondary member of the motor which acts as an inertial mass, is to be controllably translated. For improved control accuracy, the actuator system of the invention employs a pair of feedback loops, one of which monitors the current in the motor's primary winding to maintain a constant force output to the secondary member and a secondary of which monitors long term deviations from the center of the secondary member and corrects for centering offsets. An opto-electronic position sensing arrangement monitors the movement of the secondary member whereby precise control of commutation of the coils of the primary winding and a smooth translation of the secondary member are obtained.

摘要： A space deployable solar energy concentrator is formed of a dome-shaped arrangement of compactly stowable flat panel segments mounted on a collapsible, space-deployable support structure of interconnected linear components. The support structure is comprised of a plurality of tensioned, curvilinear edge strips which extend in a radial direction from a prescribed vertex of a surrounding umbrella-like framework of radially extending rib members. Between a respective pair of radially-extending, curvilinear edge strips an individual wedge-shaped panel section is formed of a plurality of multi-segment lens panel strips each of which is supported in tension between the pair of edge strips by a pair of circumferentially extending catenary cord members connected to a pair of ribs of the surrounding umbrella-like framework. A respective lens panel strip is comprised of a plurality of flat, generally rectangular-shaped, energy-directing panels arranged side-by-side in the circumferential direction of the dome. Adjacent panels are interconnected by flexible U-shaped hinges which overlap opposing edges of adjacent panels and engage respective cylindrically-shaped, load distribution bars that slide within the flexible hinges. Because each U-shaped hinge is flexible, it is permitted to shift in the circumferential direction of the panel section to facilitate stowage and deployment of the dome.

摘要： An improved narrowband continuous phase modulation system incorporates a filtering mechanism in the transmitter and receiver sites that enables the radiated spectrum characteristic to have a substantially reduced response at frequencies other than the channel of interest and thereby achieve a significant reduction in unwanted adjacent channel interference. Each of the transmitter and receiver sites contains a square root Nyquist filter upstream and downstream of the modulator and demodulator, respectively. The output of the Nyquist filter in the receiver is coupled to an accumulator which sums successive samples of the demodulated data signals (including noise). The noise is reduced as a consequence of its inherent negative correlation properties (utilized in the accumulation of successive samples of the recovered signal).

摘要： The separation constraint between the respective junctions formed between the drain regions of the complementary transistors and the semiconductor material in which they are formed is obviated by a structure which permits the respective drain regions of the opposite conductivity type transistors to have a reduced (effecting to zero) mutual separation and, at the same time, prevent the depletion regions fomed between the junctions defined by these source regions and the semiconductor material in which they are formed from spreading into contact with one another and thereby shorting the transistors together. This objective is achieved by a structure in which the source regions of the respective P and N channel transistors are formed so as to directly abut against one another and to be contiguous with a layer of buried dielectric isolation therebeneath. The buried dielectric layer extends from the bottom portions of the drain regions to a prescribed depth in each of the P-well region and the N-type substrate, so as to effectively provide a barrier between depletion region associated with the junction defined by the P well and N substrate the depletion regions formed between the N+ drain region and the P-well and the P+ drain region and the N-type substrate.

摘要： A navigation system contains a modified Kalman filter processor which continuously receives both TERCOM and SITAN control information so that the operation of the SITAN processing is effectively continuously optimized. The system employs an over flight terrain data storage map to which position and altitude signals are coupled for extracting both elevation and slope information from the stored map. The extracted elevation and slope data are coupled, together with the outputs of baromatic and radar altimeter sensors and estimated altitude and position data outputs from the navigation unit, to a correlation/modified Kalman filter processor. Elevation profile data accessed from the map is correlated with elevation profile signals derived from aircraft on-board sensors, in order to find that flight path on the stored map, parallel to, but displaced from the flight path indicated by the navigation unit, for which successive elevation data values correspond most closely to the elevations measured by the altimeter sensors. In this correlation processing operation the "most likely" path is selected by defining a performance index associated with each path and selecting that path with the best performance index. The result of the correlation processing provides a position fix to be combined with the position estimates in the modified Kalman filter.

摘要： A high speed signal processor contains a set of repetitive architecture functional units including an input data storage unit for storing quantized data values, a data shifting unit, an output data accumulator and a control code generator. The data shifting unit is coupled in parallel to each of a plurality of controllable data accumulator sections of the output data accumulator. Each accumulator section has a control input coupled to a respective output of the control data generator for defining the logic operation of the data accumulator section with respect to the contents of the data shifting unit. The data shifting unit has a plurality of stages each of which is coupled in parallel to the output stage of successive stages of the input data storage unit to which successive digitized data samples of a signal waveform to be processed are coupled. As each respective data sample is coupled to the data shifting unit, the contents of the data shifting unit are incrementally shifted and the resulting digital value is coupled in parallel to each of the sections of the output data accumulator. For each shifted value the parallel arrangement of data accumulator sections controllably combine the contents of the data shifting unit with the current data value stored in each accumulator section in accordance with control codes supplied from the programmable control signal generator.

摘要： An apparatus for detecting the onset of a potential lightning discharge condition monitors the odd harmonics of an RF signal radiated from a conductive probe (antenna) for fluctuations that are representative of an electrostatic condition-induced corona. In response to the such fluctuations, an output signal representative of the onset of said condition is generated. This output signal may be employed to decouple communication equipment from its antenna until the lightning condition has subsided. In accordance with a further aspect of the present invention, there is provided a device for discharging static charge accumulation from a moving body (e.g. an aircraft) which is comprised of at least one discharging conductive wick arranged to be affixed to the trailing edge of a wing, so that charges may flow from the aircraft into the wick and be discharged therefrom. To enhance discharging of the aircraft, a tuned (LC) circuit, resonant at a frequency within an RF spectrum of frequencies of corona discharge currents that flow through the wick, is coupled between the wing and the wick. Once the level of static charge build-up on the aircraft is sufficient to initiate corona discharge, current flow through the resonant circuit begins to self-oscillate and continues to `ring` after the D.C. voltage level on the body has dropped below that level at which corona was initiated.

摘要： A mechanism for correcting for time-varying errors that affect the pointing accuracy of a shipboard mounted antenna employs a Kalman filter for realizing an optimal correction estimator through which inputs to the antenna aiming control hardware are adjusted. A series of coordinate system transformations, corrected by the Kalman filter error estimator, are carried out to provide a command input to an antenna pointing servo system. The servo control system produces a servo error signal representative of a deviation in the actual direction of the antenna pointing mechanism from the command input to the servo loop as defined by the corrected aiming signal. The actual direction in which the servo control system points the antenna is compared with a reference (the actual direction to the satellite). As a result of this comparison, a pointing deviation signal representative of any offset from the intended pointing direction is generated. Because this pointing deviation signal depends upon the output of the servo control mechanism, it inherently contains any error in that output. Such error is removed by subtracting the servo error signal from the pointing deviation signal and applying the resultant difference signal to the Kalman filter error estimator.
