  • Method and apparatus for driving a brushless DC motor
    Patent number: 7417390
    Abstract: A drive circuit for a brushless DC motor includes a switch constructed and arranged to drive the motor with a pulse signal responsive to a control signal, and control circuitry coupled to the switch and constructed and arranged to generate the control signal responsive to rotor position information from the motor so as to synchronize the pulse signal to the rotor position. A current sensing device can be used to provide the rotor position information to the control circuitry by sensing current flowing through the motor.
    Type: Grant
    Filed: July 25, 2005
    Date of Patent: August 26, 2008
    Assignee: Analog Devices, Inc.
    Inventors: Robin Laurie Getz, David Edward Hanrahan
  • Method for automatic thermal calibration of a cooling system
    Patent number: 7047756
    Abstract: This disclosure describes a method for operating a cooling device in a thermal system that is responsive to an operating parameter and dynamically changes the operating parameter to achieve a maximum operating temperature for any system regardless of the subsystem variation.
