Abstract: An apparatus and associated method for simulating anatomic and physiological responses to medical procedures involving administering regional anesthetic/analgesic agent in real time using a mannequin. Such simulation allows trainees to perform regional anesthesia techniques that closely mimic real world medical procedures before performing procedures on live patients.

Abstract: A motor vehicle sensing and warning circuit is described that includes a series of N Schmitt triggers with MOS P-channel and N-channel enhancement devices included in a single monolithic structure to perform waveform generation, sensing, comparison and control functions. The Schmitt triggers are configured to deliver as an astable oscillator in circuit with a sensing antenna through a balance circuit as well as deliver as an audio oscillator to drive a piezo element to alert the driver of the presence of an invading object that should be avoided. Shaping and conditioning of the reference waveform are generated by the free running oscillator, as is a comparison function in association with a series of strobing diodes resulting in a strobed output summing function between a Schmitt sensing trigger and a Schmitt reference trigger associated with the free running oscillator.
