Abstract:
The invention relates generally to the field of motorized garage door openers. In particular, the invention relates to wireless safety sensors for garage door openers and garage door opener with a wireless safety sensor. The wireless safety sensor has a wireless communication link with a main control unit of the garage door opener. The wireless safety sensor also has an internal wireless link, i.e., a detection beam link, between a master unit and a slave unit. The wireless safety sensor periodically verifies that the wireless communication link has good signal quality and maintains the quality of the wireless communication link.

Claim (Index 31):
A wireless safety sensor for a garage door opener system, the garage door opener system comprising a main control unit for controlling operation of an electric motor to mobilize a garage door towards or away from a fully closed position along a door closing path, the main control unit including a main unit radio transceiver for communication with the wireless safety sensor and for receiving obstacle detection alert signal from the wireless safety sensor, the wireless safety sensor comprising:\n a sensor radio transceiver tunable to one or more frequency channels in a set of pre-selected frequency channels for wireless communication with the main unit radio transceiver, a microprocessor for controlling operations of the wireless safety sensor, a power management circuitry, the power management circuitry cooperating with the microprocessor to place the sensor radio transceiver in one of a sleep mode and a normal operation mode, and the sensor radio transceiver being placed in the normal operation mode periodically to transmit a radio initiation signal to the main unit radio transceiver for initiating verification of and to verify communication quality of the wireless communication with the main unit radio transceiver and being placed in the normal operation mode upon receiving a wireless door closing signal from the main unit radio transceiver; a detection unit, said detection unit comprising a master unit and a slave unit, the master unit being directable by at least one of the sensor radio transceiver and the microprocessor to emit a blockable detection beam to the slave unit and receive a return signal from the slave unit, the master unit providing an indication of no obstacle to the at least one of the sensor radio transceiver and the microprocessor upon receiving the return signal and providing an indication of obstacle detected to the at least one of the sensor radio transceiver and the microprocessor when fail to receive the return signal; and the sensor radio transceiver being configured to transmit a wireless signal to the main control unit according to the indication received from the master unit.
