transmission traverses each clockwise and counterclockwise stroke specifically the motor load is a minimum during agitation hesitation and a maximum during each mid stroke and the total branch circuit phase lag is a maximum during hesitation and a minimum during mid stroke this information may be processed to monitor both the average agitator mid stroke torque and the precise stroke rate since each manufacturer uses a unique gear ratio it is also possible to infer both the manufacturer and the motor speed 4 6 or 8 pole active motor winding from precise knowledge of the stroke rate unlike the above compressor motor slip rpm measurement washer agitator torque rhythmicity does not require separation of odd and even ac phase lag data hence a sure means exists to avoid confusing washer and refrigeration compressor branch circuit data from a remote location even if the installer electrician mis identifies a branch circuit various circuits and algorithms for determining the functionality discussed above as well as other functionality of various appliances are described in u s pat nos 4 481 786 5 006 778 5 101 575 5 130 624 5 038 091 5 166 592 5 237 256 5 280 227 5 281 956 and 5 564 831 in another embodiment shown in fig2 a plurality of circuit breaker switches may each be connected to a core 24 as discussed above the secondary winding of each core is connected to a multiplexer 40 which is in turn connected to the processor 32 in one approach the multiplexer 40 may be a multi channel analog multiplexer circuit such as national semiconductor mm74hc4051 the multiplexer 40 may be controlled by the processor 32 to.
