The invention may be broadly conceptualized as an approach in which a microwave oven receives a plurality of program recipes from a network that are executed by scanning with a scanner a symbol and associating the scanned symbol with one of the plurality of program recipes while keeping a real-time clock synchronized and correctly set by receiving period time synchronization messages. An amorphous silicon thin film transistor is formed on a substrate, and then the Infrared heating process is used. The compliant pin header assembly has compliant pins for engaging corresponding features on the printed circuit board to connect the compliant pin header assembly electrically to the printed circuit board. A training process is disclosed that utilizes the pseudo-rank likelihood objective function to identify model parameters that will result in a pattern recognizer with the lowest possible recognition error rate.
