Abstract: A method for manufacturing a thermoelectric module that involves obtaining a first printed circuit board having a first dielectric layer sandwiched between a first metallic substrate and a first electrical conductive layer, obtaining a second printed circuit board that comprises a second dielectric layer sandwiched between a second metallic substrate and a second electrical conductive layer, and positioning a plurality of N-type and P-type thermoelectric elements having first ends and second ends between the first and second electrical conduction layers so that the first ends of the thermoelectric elements are situated on the first electrical conductive layer and the second ends of the thermoelectric elements are situated on the second electrical conductive layer and arranged to form an electrical circuit that alternates between the N-type and P-type thermoelectric elements.

Abstract: A domestic gas appliance is disclosed. In one implementation the appliance includes a burner and a gas control valve situated to deliver and vary a flow of a gas to the burner. The gas control valve has an actuator that induces an opening and/or closing of the flow control valve dependent on a control signal delivered to the actuator. A control device is electrically coupled to the actuator and is used to control the opening and closing of the gas control valve. The control device is coupled to an audio input and is configured to receive an analog sound signal and to generate the control signal based on the analog sound signal. A method of modulating a flame in a burner of a domestic gas appliance is also disclosed. In one implementation the method includes producing an analog sound signal and subsequently creating a reference signal based on the analog sound signal.
