Patent number: 8058970Abstract: A discrete add-on control system for a barrier operating system is provided. The control system includes a mobile transmitter, a barrier state transmitter a controller and an indicator. The mobile transmitter automatically and periodically generates a mobile signal. The barrier state transmitter generates a barrier state signal. The controller is connected to the barrier operating system, receives the mobile signal and the barrier state signal, and commands the barrier operating system to move a barrier based upon the mobile signal and the barrier state signal. The indicator indicates a condition of the barrier.Type: GrantFiled: October 20, 2010Date of Patent: November 15, 2011Assignee: HomeRun Holdings CorporationInventors: Willis Jay Mullet, Yan Rodriguez, Michael Scott Swift

Patent number: 8058832Abstract: A motor driving circuit includes a control device, a detection module and a driving module. The control device is controlled by a control signal and is coupled to a motor. The control device includes a first terminal, a second terminal and a control terminal, wherein a driving current flowing through the motor flows through the first terminal and the second terminal. The detection module is used for detecting a voltage of the first terminal. The driving module is used for generating the control signal to control the driving current, wherein the detection module adjusts the driving capability of the driving module, thereby adjusting a slew rate of the control signal.Type: GrantFiled: September 25, 2008Date of Patent: November 15, 2011Assignee: Leadtrend Technology Corp.Inventor: Ching-Tsan Lee

Patent number: 8035327Abstract: A motor drive unit includes a controller configured to drive a motor to a target position by using a first driving mode in which a state of energization of coils of the motor is switched in accordance with outputs from rotor position detectors and a second driving mode in which a state of energization of the coils is switched on the basis of a predetermined time interval. The controller turns on the energization of the coils during a predetermined time under an energization condition at a completion of driving to the target position when the rotor position detectors detect that the rotor position shifts from the target position after turning off the energization of the coils according to the completion of driving to the target position.Type: GrantFiled: January 27, 2009Date of Patent: October 11, 2011Assignee: Canon Kabushiki KaishaInventor: Masao Mizumaki
