    摘要: An appliance operation signal processing system including an input for receiving an appliance operation signal. The appliance operation signal includes information relating to operation of an appliance. The system further includes an output for outputting information relating to degradation of the appliance and a processor configured to determine a probability that the appliance or a component of the appliance is in at least one degradation state by applying a classifier to a feature vector including information relating to frequency data extracted from the appliance operation signal.

    摘要: An appliance operation signal processing system comprises: an input for receiving an appliance operation signal, the appliance operation signal comprising information relating to operation of an appliance; an output for outputting information relating to a recall status of the appliance; and a processor configured to: monitor an input appliance operation signal for a change in magnitude; if a change is detected: identify a component event corresponding to the change; determine whether the component event is a designated sequence start component event; if the component event is determined to be a designated sequence start component event: extract one or more features from the input appliance operation signal between the sequence start component event and a sequence stop point; determine information relating to a recall status of the appliance by inputting the one or more features into a first algorithm.

    摘要: A utility management device, comprising an input for receiving a utility consumption signal for a premises, an output for outputting utility management information, and a processor configured to monitor the input utility consumption signal for a change in magnitude. If a change is detected, the processor is configured to identify an appliance event corresponding to the change, obtain information relating to the projected utility consumption of the appliance for an upcoming time period, update a projected utility consumption of the premises based on the obtained information, determine whether any projected stored and/or generated utility amount at the premises is sufficient for the projected utility consumption of the premises, and, if not sufficient, cause the device to output a request to receive a utility amount from one or more other premises connected to the premises via a communication network.
