Abstract: The present disclosure describes a domestic appliance communication system that provides consumers with the ability to remotely access information about their domestic appliances, and in particular domestic appliances which utilize consumable resources which may need to be periodically replaced or replenished. The domestic appliance communication system may periodically receive status information from the domestic appliances owned by a consumer or household and provide updated status information to the consumer, either on demand or via alerts triggered in response to certain events. The present disclosure also describes implementations and improvements which may be made to domestic appliances in order to provide periodic measuring and transmitting of status information to a remote system, such as the domestic appliance communication system.

Abstract: Stimulating power line carrier injection with reactive oscillation comprises exciting a tank circuit to oscillate at the carrier frequency by sinking pulses of current between one node of a capacitor in the tank circuit and the other node of the capacitor. A power transformer is connected to a distribution system to inject a power line carrier onto the power line. An excitation circuit sinks short pulses of current between one node of a capacitor and the other node of the capacitor that is connected in a tank circuit arrangement with an inductor and the secondary winding of the power transformer. The tank circuit oscillates at the frequency of the excitation pulses if the resonant frequency of the tank circuit is close to the frequency of excitation. The oscillating current is coupled onto the power line system through the power transformer. The phase of the power line carrier signal is shifted by shifting the phase of the excitation pulses.
