Patents by Inventor Dave Rutkowski

Dave Rutkowski 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).

  • Saturated transistor based temperature sensor
    Patent number: 7600913
    Abstract: A system for measuring a temperature of an electrical device is provided. The system comprises a transistor and a microprocessor. The transistor is part of an electrical device and is operable to perform a first function for the electrical device. For example, the transistor is operable in a saturated state to control activation of a pre-charge circuit in an electronic power assisted steering system. The microprocessor is responsive to a voltage at the transistor. The voltage of the transistor varies as a function of temperature (i.e., heat emitted from the electrical device). The microprocessor is operative to determine a temperature of the electrical device as a function of the voltage, where the sensing of temperature of the electrical device is different than the first function.
