  • Miniature ingestible telemeter devices to measure deep-body temperature
    Patent number: 3971362
    Abstract: A miniature, ingestible and encapsulated telemeter device for transmitting information relating to deep-body temperature of a subject comprising a battery source of power, and a free running multivibrator circuit having fixed biasing means connected to oscillator having a predetermind resonant frequency. A thermistor having a negative temperature coefficient of resistance is connected to the battery and the fixed biasing means and is operative to vary the output frequency of the multivibrator circuit in proportion to the temperature of the thermistor, the oscillator being pulsed into alernate states of conduction and non-conduction at the output frequency of the multivibrator to produce an output consisting of bursts of energy at the predetermined resonant frequency, preferably in the range 88 - 108 MHz.
