System and method for identifying appliances under recall

Abstract

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; anda 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.

1 . An appliance operation signal processing system comprising:
 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.
