  • Missile Telemetry Data Interface Circuit

  • US Patent:
    56546980, Aug 5, 1997
  • Filed:
    Apr 8, 1996
  • Appl. No.:
    8/631287
  • Inventors:
    Andrew H. Snelgrove - Ventura CA
    Guy R. Buchwitz - Oxnard CA
    Paul H. Sailer - Ventura CA
  • Assignee:
    The United States of America as represented by the Secretary of the Navy - Washington DC
  • International Classification:
    G08C 1916
  • US Classification:
    34087001
  • Abstract:
    An interface circuit which receives a PCM telemetry data stream comprising waveform divided into 100 words including a three word frame sync signal. The PCM data stream is supplied to a comparator which converts input telemetry signal to a TTL compatible signal. When the PCM data is unencrypted, the PCM data stream is supplied to a de-randomizer circuit which de-randomizes the randomized data. A bit sync circuit which also receives the PCM data stream generates a 320 kHz clock signal which is synchronized to the incoming PCM data stream. The de-randomized PCM telemetry data stream which is in a serial format and the 320 kHz clock signal pass through a digital multiplexer to a universal synchronous asynchronous receiver transmitter. When the receiver transmitter detects a PCM frame sync signal for a frame of PCM data, it interrupts a master microprocessor which then retrieves each word of PCM data from the frame. The master microprocessor writes the frame of PCM data into one bank of a dual Port RAM.

  • US Patent:
    56105983, Mar 11, 1997
  • Filed:
    Mar 18, 1996
  • Appl. No.:
    8/619289
  • Inventors:
    Guy R. Buchwitz - Oxnard CA
    Andrew H. Snelgrove - Ventura CA
    Paul H. Sailer - Ventura CA
  • Assignee:
    The United States of America as represented by the Secretary of the Navy - Washington DC
  • International Classification:
    G08C 1916
  • US Classification:
    34087007
  • Abstract:
    An interface circuit for receiving an analog PAM telemetry data stream from missile's telemetry unit. The PAM data stream comprises a waveform divided into 64 channels and includes a sync signal. The PAM data stream is supplied to a filter which removes from the PAM data stream subcarrier channel oscillator frequencies. The filtered data stream is next supplied to an analog-to-digital converter which converts each sample of the data stream to an equivalent twelve bit PAM data word which is supplied to a slave microprocessor. The slave microprocessor processes each of the sixty four PAM channels by utilizing a 25. 6 kHz PAM clock signal generated by a PAM signal processing circuit. The slave microprocessor first checks for the sync signal. When the sync signal is decoded, the slave microprocessor sends a message to a master microprocessor via a dual port RAM indicating that the sync signal was located. The master microprocessor will respond with an acknowledgement message to the slave microprocessor.

  • US Patent:
    54954169, Feb 27, 1996
  • Filed:
    Nov 7, 1994
  • Appl. No.:
    8/335560
  • Inventors:
    Guy R. Buchwitz - Oxnard CA
    David H. Muskat - Camarillo CA
  • Assignee:
    The United States of America as represented by the Secretary of the Navy - Washington DC
  • International Classification:
    G01C 2100
  • US Classification:
    364449
  • Abstract:
    An audio information apparatus for providing position information as to the ocation of a target comprising a global positioning system receiver affixed to the target for generating a string of fifty ASCII characters representing the latitude and longitude spherical coordinates of the target. The fifty ASCII characters are supplied to a microprocessor which converts a predetermined number of the fifty characters to a plurality of a four bit addresses. The four bit addresses are supplied to a digital voice module which generates an analog audio voice signal in response to the four bit addresses. The analog audio voice signal which represents the location of the global positioning system receiver is supplied to a speaker. The speaker then broadcast the exact location of the global positioning system receiver. The analog audio voice signal is also supplied to a transmitter for transmission of the signal to a ground station.

    55529933, Sep 3, 1996
  • Filed:
    Dec 5, 1994
  • Appl. No.:
    8/349757
  • Inventors:
    Guy R. Buchwitz - Oxnard CA
    David H. Muskat - Camarillo CA
  • Assignee:
    The United States of America as represented by the Secretary of the Navy - Washington DC
  • International Classification:
    G06F 1550
  • US Classification:
    364449
  • Abstract:
    An audio information apparatus for providing position information as to the ocation of a target comprising a global positioning system receiver affixed to the target for generating a string of fifty nine ASCII characters representing the latitude and longitude spherical coordinates of the global positioning receiver affixed to the target. The ASCII characters are supplied to a microprocessor, which in response to the ASCII characters, formulates a position message indicating the current location of the global positioning system receiver. A pair of voice recorder/playback circuits, coupled to the microprocessor, have a message table which includes 27 messages or words which when assembled in a predetermined sequence form a longitude and latitude coordinate position message. When the voice recorder/playback circuits are in a message cueing mode, the microprocessor provides a predetermined number of active low chip enable pulses to a selected one of the pair of voice recorder/playback circuits to select the desired word from the table. The microprocessor then disables the message cueing mode which, in turn, enables an audio amplifier of the selected one of the voice recorder/playback circuits.
