  • Patent number: 4673146
    Abstract: An improved missle tail fin assembly. The missile utilizes four tail fin assemblies, each assembly comprising a fitting having three locking portions, each of which comprises a gudgeon having a pair of locking teeth, and a fin having mating recesses for the locking portions. A portion of the material associated with recesses of the two forward locks of each fin is removed, leaving clearances which permit limited rotation about the fin pivot axis in one direction only. When the fin is loaded in a direction to produce clockwise torque, all three locks which form the lock assembly are loaded approximately equal and this locates the elastic axis of the tail lock approximately just aft of the center of pressure which produces a small increase in cant angle with load. When the tail is loaded in the direction to produce a counterclockwise torque, the aft lock of the assembly will take all the torque. This moves the elastic axis further aft thus producing a larger increase in cant angle with load.

  • Patent number: 4674029
    Abstract: An open-loop system for controlling a plant, including a sampling circuit for providing an actuating signal as a series of impulse signals, and a computer for providing a control signal to operate the plant in response to the actuating signal in accordance with a control function defined by a control algorithm based upon a calculated response of the plant in an equivalent closed-loop linear control system. The computer provides the control signal as a function of time following the application of each impulse signal. The control algorithm is a time-domain algorithm based upon an inverse LaPlace transform of the equivalent system. The interval between impulse signals, as defined by the sampling rate, is on the order of the time constant of the equivalent system; and the computation speed of the computer is sufficiently fast to provide a control signal that is effectively continuous relative to the operating dynamics of the plant.

  • Patent number: 4669054
    Abstract: A two-dimensional optical correlation apparatus includes a transmissive optical mask having a transmissivity pattern corresponding to a two-dimensional reference image and an input image buffer that stores a sequence of pixels corresponding to a raster-scanned input image. The input buffer includes a subimage frame corresponding to a particular segment of the raster-scanned format. As the pixels are serially shifted through the image buffer, every subimage in the input image appears at some time in the subimage frame. The subimage frame is connected to an array of optical emitters. As the input image pixels are serially shifted, the emitter array produces a succession of two-dimensional optical signals corresponding to the succession of input image subimages shafted through the subimage frame. The output of the emitter array is projected onto the transparent mask.

  • Patent number: 4667899
    Abstract: A self-erecting wing structure for increased missile performance and maneuverability without significant sacrifice of payload space includes a wing pivotally attached to an air frame in a retracted position in which the wing is both rotated about its spanwise axis relative to an erected position and pivoted forward alongside the air frame. Rotational components enable passing air to swing the wing to the erected position when it is released from the retracted position during flight. A secondary wing surface is included that automatically deploys to increase wing area.

  • Patent number: 4660170
    Abstract: A system for providing information to alter the software of an electronic data processor embedded in an electronic module includes a remote reprogramming module that conducts a sequence of operations to provide data to the processor which the processor uses to reprogram itself. The system employs a data link having a bi-directional transmission path connecting the processor and the reprogramming module. A controlled switching circuit is provided at each end of the transmission path. Under normal operating conditions, the transmission path is used to transit a function signal for a function performed by the electronic module. Periodically, the processor operates one switching network to capture the path for transmission of a reprogramming inquiry signal to the reprogramming module. At the same time, the function signal is diverted to an alternate path internal to the electronic module.

  • Patent number: 4651297
    Abstract: The electro-optical correlator performs pattern-recognition by forming the columnar dot product of an input image with a reference image at video through-put rates. The correlator incorporates an analog-to-digital converter for digitizing the input-image data, a plurality of serially arranged delays having a delay time equivalent to one input-image data line, each delay for receiving in turn the digitized input data and for producing a parallel output signal, and a vertical column of photodiodes for receiving the respective multiple parallel delayed signals and for converting same to an optical output. The optical output is fed through a lens, reference image mask, and lens unit and is focused on a plurality of photodiodes that are connected to a time-delay-and-integrate (TDI) array. The data from the time- delay-and-integrate array are clocked through an analog-to- digital converter which produces the final system output. The time delay and integrate array may be a charge-coupled device (CCD).

  • Patent number: 4647873
    Abstract: An apparatus and method for generating an output signal having portions thereof being linearly swept in frequency. A controller, responsive to external signals, generates a series of control signals. An oscillator, responsive to each one of the control signals, produces an output signal. The output signal includes a series of output waveforms each linearly swept in frequency and corresponding to a respective one of the control signals. A first servo, responsive to each one of the output waveforms, produces a series of first correction signals each dependent upon the linearity error in a corresponding one of the output waveforms. The first correction signals modify a corresponding control signal as applied to the oscillator so as to correct linearity errors occurring in a corresponding one of the output waveforms. A second servo, responsive to each one of the first correction signals, produces a series of second correction signals each dependent upon the correlations in the first correction signals.

  • Patent number: 4620293
    Abstract: An optical computing system is provided for performing a linear multiplication operation involving a matrix with bipolar values. A plurality of beams representing the values of a N.times.1 column matrix Q illuminate an optical mask having elements disposed in a two-dimensional (M+1).times.N array. Each element of the first M rows of the mask represents the offset of the value of a corresponding element in a known M.times.N matrix by a scalar constant c. Each element of row M+1 of the mask represents the value c. An array of photodetectors collects the light passing through the mask, with the light from each row of elements detected by a respective photodetector. The outputs of the first M photodetectors represent the product of Q and M after M has been offset by c. The output of photodetector M+1 represents the scalar value produced by the multiplication of Q and a row matrix represented by row M+1 of the mask matrix.

  • Patent number: 4604570
    Abstract: A ballistic comparative ohmmeter for use in testing the resistance between different selected pairs of a plurality of terminals in a test circuit in comparison to the resistance between corresponding pairs of terminals in a reference circuit. the ohmmeter is particularly useful for making resistance tests in circuits included in assembled products. The ohmmeter makes comparative resistance tests during a transient response period following application of the current to the selected pair of terminals as well as under steady state conditions. Solid state stepping switches that are sequentially stepped by pulse counters are utilized to sequentially connect different combinations of terminals in the test circuit and the reference circuit. Protection circuits limit the voltages applied across the test circuit and master circuit terminals. Indicator panels immediately provide a steady state indication of the pair of terminals in the test circuit at which a fault is detected.
