Wideband, High-Input-Impedance Buffer Amplifier
Improved buffer amplifier offers high input impedance to signal source. Input impedance remains high, relatively constant, and essentially resistive over wide range of frequencies.

Implantable, Ingestible Electronic Thermometer
Small quartz-crystal-controlled oscillator swallowed or surgically implanted provides continuous monitoring of patient's internal temperature. Receiver placed near patient measures oscillator frequency, and temperature inferred from previously determined variation of frequency with temperature. Frequency of crystal-controlled oscillator varies with temperature. Circuit made very small and implanted or ingested to measure internal body temperature.
