Surender K. Gulati 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).

  • Multiple self-contained logic gate counter circuit
    Patent number: 4513432
    Abstract: A multibit counter circuit uses a plurality of essentially identical stages which each have a feedback circuit, a flip-flop, and a carry circuit. Each of the stages is connected together in essentially the same way. A counter circuit of any desired bit capacity can be relatively quickly and easily formed with a saving in silicon area compared to standard configurations.

  • Noise rejection Set-Reset Flip-Flop circuitry
    Patent number: 4506165
    Abstract: Set-Reset Master-Slave Flip-Flop circuitry uses a feedback circuit connected to a circuitry output terminal and to set and reset input terminals to limit the effect of spurious signals such that only signals applied to set and reset terminals which are of the appropriate state at least prior to and during the transition of a clock signal from the low to the high state cause the output terminals of the Flip-Flop to be set to or maintained in preselected levels.
