Patent number: 10544613Abstract: This invention is about an improved garage door opener system, with design features for preventing garage door break-in from outside of the garage using an object such as a hanger. Typically, a person pulls down a cord connected to a release handle to release emergency release of a garage door opener, allowing the door to be manually open or closed. An unauthorized person may attempt to pull down the cord using a hanger from outside the garage or to pull or push down the release handle, to open the door from outside and gain unauthorized entrance. The improved garage door opener system provides a mechanism to reverse the pulling direction of the cord and also protects release handle from being accessed from outside the garage, for increased security.Type: GrantFiled: February 9, 2018Date of Patent: January 28, 2020Inventors: Philip Yu Wing Tsui, Gallen Ka Leung Tsui

Patent number: 9343990Abstract: The invention provides a low current consumption control switch device and method related thereto. The control switch device includes a switch control component, a microprocessor, a wireless signal receiver for receiving control signal and a DC power supply. The DC power supply draws an AC current from the AC power supply to power the wireless signal receiver, the microprocessor and the switch control component. The switch control component has a control input for receiving control instructions to control current supply from the AC power supply. The microprocessor is operatively connected to the switch control component for providing control instructions to alter its switching state. The control signal comprises a preamble and a message portion. The wireless signal receiver is configured to alternate between at least two current consumption modes and to remain in a higher current consumption mode upon detection of the preamble.Type: GrantFiled: September 15, 2011Date of Patent: May 17, 2016Inventors: Philip Yu Wing Tsui, Gallen Ka Leung Tsui

Patent number: 8976002Abstract: A universal remote control system is disclosed. The universal remote control includes a receiver that has a wireless signal receiver unit, an electric motor that drives a mechanical arm and a microprocessor. When the receiver receives a control signal from a wireless signal transmitter, the microprocessor will energize the motor which drives the mechanical arm toward a pushbutton switch of a controlled device, such as a garage door opener, and depresses the push button, therefore activating the garage door opener. A feedback signal, for example, from the mechanical arm or the motor, may be provided to the microprocessor to inform the microprocessor when the pushbutton switch is sufficiently depressed and is in an engaged state. When the switch is in the engaged state, the motor will reverse its direction, causing the mechanical arm to raise and move back to a standby position.Type: GrantFiled: August 20, 2013Date of Patent: March 10, 2015Inventors: Philip Yu Wing Tsui, Gallen Ka Leung Tsui
