Us Patents

  • Multiple Matrix Switching System

    view source
  • US Patent:
    43002072, Nov 10, 1981
  • Filed:
    Sep 25, 1979
  • Appl. No.:
    6/078900
  • Inventors:
    Donald J. Eivers - Massapequa NY
    Eddie J. Kovacs - Kings Park NY
  • Assignee:
    Grumman Aerospace Corporation - Bethpage NY
  • International Classification:
    G01R 3128
  • US Classification:
    364900
  • Abstract:
    A multiple matrix switching system for use in connecting a unit under test to one or more external instruments which may either provide a signal input to the unit under test or measure the output of the unit under test is disclosed. Matrix switching allows connections between the unit under test and each external instrument to be effected with only two switching elements. Switching system control to select a signal path is accomplished by means of a microprocessor which resolves switching path conflicts through switching system status monitoring.

  • US Patent:
    47194596, Jan 12, 1988
  • Filed:
    Mar 6, 1986
  • Appl. No.:
    6/836929
  • Inventors:
    Eddie T. Kovacs - Kings Park NY
    Donald J. Eivers - Massapequa NY
  • Assignee:
    Grumman Aerospace Corporation - Bethpage NY
  • International Classification:
    H04Q 1100
    G01R 3128
  • US Classification:
    340825800
  • Abstract:
    The signal distribution function in a signal distribution system is performed in a switching matrix under the control of a hybrid controller. With respect to the switching matrix, there are approximately 120-140 available interface I/O connections such that an equipment under test can be selectively connected to any one of a plurality of test instruments. The relays within the switching matrix are selectively activated such that a signal path connecting the equipment under test to a particular test instrument can be accomplished with a minimum amount of switching path conflicts.

  • Signal Distribution System Hybrid Relay Controller/Driver

  • US Patent:
    47631244, Aug 9, 1988
  • Filed:
    Mar 6, 1986
  • Appl. No.:
    6/836927
  • Inventors:
    Eddie T. Kovacs - Kings Park NY
    Donald J. Eivers - Massapequa NY
  • Assignee:
    Grumman Aerospace Corporation - Bethpage NY
  • International Classification:
    H04Q 900
    G01R 3128
  • US Classification:
    340825800
  • Abstract:
    A hybrid controller is used to control a plurality of relays, within a switching matrix, for effecting connection of an equipment under test to at least one of a plurality of test instruments. To do so, the hybrid controller utilizes latch drivers which are capable of driving 24 relays simultaneously. To check whether or not the correct relay is activated, drivers are used to sense the statuses of the relays and forward the information to a central processing unit for comparison. The drivers are controllably actuated by a decoder means, which in turn is controlled by the central processor.
