  • SYSTEM AND METHOD FOR PROVIDING HOLD-UP POWER TO A LOAD
    Publication number: 20130285449
    Abstract: A power system and method includes a power source; one or more loads that receive power from the power source; a boost circuit for stepping up an input voltage from a primary power source; a capacitor for storing a stepped up voltage from the boost circuit; and a buck circuit for stepping down a voltage from the capacitor, and providing a stepped down voltage to the one or more loads when the power source is unavailable.

  • Systems and methods for minimizing stray current in capacitive sensor data
    Patent number: 8365574
    Abstract: A method for minimizing stray current in capacitive sensor data includes receiving a first input from a first wire of a wire harness, the wire harness comprising a plurality of twisted wires, the first input comprising a first signal comprising first sensor data and stray current; receiving a second input from a second wire of the wire harness, the second input comprising a second signal comprising stray current; and subtracting the second signal from the first signal to determine the first sensor data. A system for minimizing stray current in capacitive sensor data is also provided.
