Abstract: The invention provides a remote controlling system for controlling a plurality of electronic equipments disposed within a situation, such as a home, a classroom, an office . . . etc. By use of the remote controlling system, a user can conveniently control the electronic equipments in the situation through a user interface or an external communication network such as a radio telecommunication network.
Abstract: The invention provides an omni-directional radiation-based signal transmitting apparatus which includes a circuit board and a plurality of radiation-based signal transmitting components. In particular, the radiation-base signal transmitting components are soldered and arranged on the circuit board such that the signal coverage zone of each radiation-based signal transmitting component overlaps the signal coverage zones of the neighboring radiation-based signal transmitting components.
Abstract: The invention provides a remote controlled power switch including a line interface, a radiation-based receiver and a processor. The line interface is electrically connected in series to a power line. The radiation-based signal receiver functions as receiving a radiation-based signal and converting the radiation-based signal into an operative code. And, the processor controls, based on the operative code, the line interface to cut off or provide transmission of electric power transmitted through the power line.
