An ultrasonic motion generator includes a non-resonant inverter, an ultrasonic transducer, and a comparator. The non-resonant inverter inverts direct current (DC) to alternating current (AC) having a first frequency. The ultrasonic transducer is electrically coupled with the non-resonant inverter and generates an ultrasonic motion based on the inverted AC. The comparator automatically detects a deviation of the first frequency from a resonant frequency of the ultrasonic transducer based on motion current passing through the ultrasonic transducer and generates an output signal based on the deviation to drive the non-resonant inverter.

The invention provides a pattern recognition processing apparatus and a technique for realizing a neural network of a complex structure within the processing apparatus. The apparatus includes a neural network having two-dimensional layers connected to form a feed-forward systolic array. Each two dimensional layer includes a feature extraction layer connected with a positional error absorbing layer. A host system provides inputs to the network. Each layer within the network includes processing elements such as a MOS analog circuit that receives input voltage signals and provides output voltage signals.
