  • Hybrid MEMS microfluidic gyroscope
    Patent number: 10563982
    Abstract: A hybrid MEMS microfluidic gyroscope is disclosed. The hybrid MEMS microfluidic gyroscope may include a micro-machined base enclosure having a top fluid enclosure, a fluid sensing enclosure and a bottom fluid enclosure. The hybrid MEMS microfluidic gyroscope may include a plurality of cantilevers disposed within the bottom semi-circular portion of the micro-machined base enclosure or a single membrane disposed within the bottom semi-circular portion of the micro-machined base enclosure.
    Type: Grant
    Filed: August 28, 2017
    Date of Patent: February 18, 2020
    Assignee: The University of Cyprus
    Inventors: Julius Georgiou, Charalambos Michael Andreou

  • Real time dynamic optimization of deadtime
    Patent number: 8760891
    Abstract: A deadtime optimization apparatus and method may determine when it is safe to turn a switch ON, eliminating the need to have a switch controller purposely insert a deadtime period in the algorithm (i.e., it can go back to producing ideal PWM). Since the decision of when it is safe to turn ON the switch may be achieved through measurement, it is expected that the length of time may change for each pulse as the operating conditions change. Therefore, the apparatus and methods of the present invention may take on a dynamic characteristic because the safe to turn ON (STTO) time may vary for each pulse.
