  • System and method for determining barrier motor parameters without using sensors
    Patent number: 7372224
    Abstract: A barrier operator comprises a first measuring apparatus for measuring a current used by a direct current (dc) motor to move a barrier and a second measuring apparatus for measuring a generated voltage of the dc motor. A controller is coupled to the first measuring apparatus and the second measuring apparatus. The controller is programmed to calculate a torque of the dc motor by using the current and to determine when an obstruction exists in the path of the barrier based upon the calculated torque.

  • Barrier movement operator human interface method and apparatus
    Patent number: 7181203
    Abstract: A programmable transmitter that verbally questions a user with audible questions to determine a type of a transmitter being emulated. The transmitter receives indicia of the type the transmitter and determines the type of the necessary transmission parameters based upon the received indicia. For operator system types that utilize DIP switch programming, the transmitter provides a voice menu of possible DIP switch settings and the user responds to the voice menu. The transmitter receives responses from the user via buttons and/or the user's voice commands.
