    Biotelemetry system for ambulatory patients (1978)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Compact transmitter for multichannel telemetry of medical data is carried in patient's belt. Pulse-code modulation (PCM), is used for high-quality signal, and low-power CMOS integrated circuits make miniaturization possible. Transmitter is useful for electro-encephalograms (EEG) and electro-cardiograms (EKG) and other biomedical patient-monitoring situations.

    Multichannel implantable telemetry system (1977)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Multiplexed biotelemetry system for animal research combines several power-saving features. Implantable sensor measures up to eight parameters simultaneously, including blood flow. Microamp transistors, switching circuits, and CMOS technology are used to lower power requirements. However, when blood flow is monitored, these measures are insufficient to reduce power enough for long-term operation from implantable primary battery.

    Remotely-powered intracranial pressure monitor (1979)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Implantable RF powered monitor uses capacitive transducer and stiff metal diaphragm that gives high stability for long term intracranial pressure monitoring. Design of monitor reduces risk of infection while improving patient comfort and mobility.
