A remote controller is provided. The remote controller includes a motion sensing circuit and a wireless communication circuit electrically connected to the motion sensing circuit. The motion sensing circuit determines whether or not a motion of the remote controller complies with one of multiple reference motions. When the motion of the remote controller complies with one of the reference motions, the wireless communication circuit is switched from a sleep state to a working state. The wireless communication circuit that is in the working state determines whether or not a received signal strength indication between the remote controller and a controlled device is greater than or equal to a strength threshold. When the received signal strength indication is less than the strength threshold, the wireless communication circuit is switched from the working state to the sleep state.

A method for suppressing a change of wireless power includes a parameter setting step, a first power verifying step, a power adjusting step and a second power verifying step. The parameter setting step is performed to set a power parameter set. The first power verifying step is performed to verify whether a first power difference is greater than the power adjustment start difference to generate a first verification result. The power adjusting step is performed to drive a processing unit to adjust the power amplifying unit according to the adjustment parameter set. The second power verifying step is performed to verify whether a second power difference is smaller than or equal to the power adjustment stop difference to generate a second verification result. The processing unit determines whether the power adjusting step is performed according to one of the first verification result and the second verification result.

Method and device for suppressing change of wireless power

A lens adjustment device includes a base assembly, a lens assembly, a light blocking member and an elastic member. The lens assembly is disposed on the base assembly and is rotatable relative to the base assembly along an axis. The light blocking member is disposed between the base assembly and the lens assembly. The light blocking member is rotatable relative to the lens assembly and the base assembly. The light blocking member is movable along the axis between a first predetermined position and a second predetermined position. The elastic member abuts against the light blocking member to provide an elastic force for moving the light blocking member from the second predetermined position toward the first predetermined position such that the light blocking member abuts against the base assembly.

Lens adjustment device

A lighting apparatus, a method and a system for processing an emergency procedure are provided. The system includes two or more lighting apparatuses that are interconnected for forming a mesh network over an area. In the method, the lighting apparatus is activated to illuminate a surveillance zone under an emergency mode. In the meantime, a camera circuit is driven to capture a series of images of the surveillance zone for conduct motion detection. When a moving object is detected, the lighting apparatus transmits a beacon signal in response to the detection result. In the meantime, an acknowledgement signal in response to the beacon signal is generated by a signal source and received by the lighting apparatus. After that, the identifier with respect to the lighting apparatus is transmitted to a control center for obtaining the position of the lighting apparatus.
