The invention relates to apparatus and methods for stimulating living tissues to determine nerve conduction properties using a pair of stimulator probes and a plurality of detection electrodes. The invention overcomes the problem of reporting potentially inaccurate nerve conduction results by detecting a stimulator probe short or shunt condition during nerve conduction tests. Detection of a short or shunt condition between two stimulator probes is accomplished by monitoring the magnitude of the stimulus artifact waveform acquired from the detection electrodes and the voltage difference between the stimulator probes. A test is flagged when magnitude of the stimulus artifact waveform is below a first threshold and voltage difference between the two stimulator probes is below a second threshold. The first and second threshold values are determined based on the known spatial relationship between the stimulator probes and detection electrodes. Feedback is provided to the tester to alert defective test conditions.

The ultrasonic thermometer system of the present invention includes a rod or probe of high temperature, grain-stabilized material that has a magnetostrictive or piezoelectric transducer bonded to one end. The transducer is excited by a transducer driver, creating short, periodic, ultrasonic pulses that travel down the length of the rod in a &ldquo;pulse-echo&rdquo; fashion. Along the length of the rod, circumferential grooves are cut which reflect some of the ultrasonic energy back to the transducer thus creating a reflected or echo signal. Two such reflected signals from two adjacent grooves, or a signal from one groove and a signal from the end of the rod, establish a temperature zone. This is the zone of interest to the user, which would be inserted into the user's process that needs to have the temperature monitored. As the temperature of the zone changes, the transition time of the ultrasonic pulse through the zone also changes, thus providing a measurable indication of average temperature and changes in average temperature of the temperature zone. There may be one or multiple temperature zones on one rod. A processor is also provided to correlate the signals generated by the transducer and reflected by the grooves with template signals to generate a temperature reading.
