Journal of Experimental Child Psychology, 1969
Abstract The development of biotelemetry is traced out from its beginnings with the transistor 20 years ago and the endoradiosonde about 10 years ago. The areas studied up to this point are then reviewed, and possible applications of the technique are considered in relation to child study.

Optimization of infrared biotelemetry systems
Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002An infrared telemetry system is analysed, particulary on the receiver side. How an array of photodiodes and choice of optimal load resistance can improve the photoreceiver sensitivity in current and photovoltaic mode is shown. In photovoltaic mode also a parallel load resistor to each diode is necessary to obtain highest photo voltage. Pulse modulation

Securing Mobile Devices with Biotelemetry
2011 Proceedings of 20th International Conference on Computer Communications and Networks (ICCCN), 2011As the value of information placed on mobile devices increases, so does the risk that the information will be lost or stolen. In dire scenarios, such as soldiers on the battlefield, there is a tension between accessing critical information quickly and protecting that information from unauthorized viewers.

A Micropower, Multichannel Biotelemetry System
Psychophysiology, 1974ABSTRACTIn order to gather biodata in the home environment, we have developed a compact and inexpensive FM multichannel subcarrier system employing micropower integrated circuits of the unique lateral PNP design. The subcarrier system may be used with or without a wireless transmitter.

Biotelemetry and Computer Analysis of Electrocardiograms
Methods of Information in Medicine, 1969Routine transmission of electrocardiograms and their computer interpretation via long-distance telephone lines has been proven feasible in the Automated Electrocardiogram Project of the Missouri Regional Medical Program. Though this Pilot Project — the first on a state-wide basis — is still viewed as an applied research effort rather than a service ...

A novel filter bank for biotelemetry
Australasian Physics & Engineering Sciences in Medicine, 2001In a multichannel biotelemetry system, signals taken from a patient are distributed along the available frequency range (bandwidth) of the system through frequency-division-multiplexing, and combined into a single composite signal. Biological signals that are limited to low frequencies (below 10 Hz) modulate the frequencies of respective sub-carriers ...

A multichannel biotelemetry system
Proceedings of the 1992 International Biomedical Engineering Days, 2003A radiotelemetry system is developed to analyze several physiological parameters from free ranging patients within a transmission range of 100 meters. Parameters considered are two independent electromyogram (EMG), an electrocardiogram (ECG) and body position information. A battery status indicator signal is also transmitted. >

Biotelemetry, 1977
A summary of considerations for design and application of multichannel biotelemetry systems is given. The advantages but also the problems of wired, wireless, combined and storage telemetry are discussed in connection with its application. Modulation and multiplexing techniques are described extensively; however, this review focuses not only on the ...
