A remote controller device includes a wireless user-operated module and a multi-function module. The wireless user-operated module is operable so as to generate control signals for controlling operation of an electrical appliance, and includes a signal receiver, a sound generator, and a signal processor coupled to the signal receiver and the sound generator. The multi-function module is operable so as to transmit a paging signal for wireless reception by the signal receiver of the user-operated module. The signal processor responds to the paging signal received by the signal receiver of the user-operated module by activating the sound generator to generate an audible sound output.

A thermocouple structure capable of providing a more compact thermopile-based thermal sensor. The thermocouple structure has a stacked configuration that includes a plurality of first conductors on a surface, a dielectric layer on each of the first conductors, and a plurality of second conductors on the dielectric layer and formed of a different material than the first conductors. Each first conductor has first and second ends, and each second conductor has a first end overlying and contacting the first end of one of the first conductors, and a second end overlying but separated from the second end of the first conductor by the dielectric layer. A plurality of third conductors electrically interconnect one of the second ends of the second conductors with one of the second ends of the first conductors. Each third conductors is thicker than the second conductors to promote the robustness of the connection.
