  • Method and apparatus for determining motor operation states
    Patent number: 10451474
    Abstract: An apparatus and method for determining an operational state of a motor are described. The apparatus includes a sensor or detecting vibration and a processor coupled to the sensor. The processor converts sensed vibration signals into the frequency domain to produce a vibration characteristic, and determines a current operational state of the motor based on the vibration characteristic, wherein the current operation state is determined from at least two different operational states including at least one idle state and at least one working state.
    Type: Grant

  • Vehicle locating unit with input voltage protection
    Publication number: 20060261934
    Abstract: A vehicle locating unit with a receiver for receiving a signal from a network of communication sources, a transponder activated when a communication source sends a message to the receiver, and a power supply regulating circuit for regulating a nominal input voltage and powering the receiver and the transponder. A protection circuit is responsive to an injected input voltage and configured to clamp the injected (high level) input voltage at a predetermined maximum voltage.
