Patents by Inventor Winston G. Walker

Winston G. Walker 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).

  • Patent number: 5444339
    Abstract: A mini-blind actuator has a motor and a housing that holds the motor and a dc battery. The rotor of the motor is coupled to the baton of the mini-blind for rotating the baton and thereby opening or closing the slats of the mini-blind. A control signal generator generates a control signal for completing the electrical circuit between the battery and the motor. The control signal can be generated in response to a predetermined amount of daylight or in response to a user-generated remote command signal.
    Type: Grant
    Filed: June 11, 1993
    Date of Patent: August 22, 1995
    Assignee: Harmonic Design, Inc.
    Inventors: Douglas R. Domel, Winston G. Walker
  • Patent number: 5391967
    Abstract: A mini-blind actuator has a motor and a housing that holds the motor and a dc battery. The rotor of the motor is coupled to the baton of the mini-blind for rotating the baton and thereby opening or closing the slats of the mini-blind. Alternatively, the rotor is coupled to the tilt rod of the blind to rotate the tilt rod and thereby open or close the slats of the mini-blind. A control signal generator generates a control signal for completing the electrical circuit between the battery and the motor. The control signal can be generated in response to a predetermined amount of daylight or in response to a user-generated remote command signal.

  • Patent number: 4163161
    Abstract: An automatic voltage regulating system for an integrated circuit having a plurality of enhancement mode metal oxide semiconductor field effect transistors on a common semiconductor crystal, the regulation system including a group of series connected metal oxide semiconductor field effect transistors on the same crystal, wherein the combined threshold voltage of such regulating transistors forms a reference to control the bias voltage for the remaining transistors.
