Joseph Gabris has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Programmable synchronous sequential state machine or sequencer having decision variable input mapping circuit responsive to feedback signals
    Patent number: 4755967
    Abstract: A programmable sequencer 10 uses an input mapping circuit 20 including a programmable logic array 30 to map decision variable input conditions onto branch address signals, which are used with primary address signals to form a next state address for state word memory 50. Input mapping circuit 20 preferably includes a branch control circuit 40, controlled by feedback signals from the output of state word memory 50, to selectively transform branch address signals to allow different states to use state word locations sharing the same primary address in state word memory 50. The preferred embodiment also includes a diagnostic circuit 80 useful for programming, and/or diagnosing operation of, sequencer 10.
