Characteristics of Oestrus Measured Using Visual Observation and Radiotelemetry

Animal Reproduction Science, 2003
The aim of this study was to measure the level of agreement between characteristics of oestrus measured using visual observation and radiotelemetry. Oestrous cycles in 20 non-lactating Holstein cows were synchronised by treatment with an intravaginal ...

Detection of Estrous Behavior in Buffalo Heifers by Radiotelemetry Following PGF2α Administration During the Early or Late Luteal Phase

Animal Reproduction Science, 2014
This study examined the usefulness of radiotelemetry for estrous detection in buffalo heifers and the impact of prostaglandin F2α (PGF2α) administration during the early or late luteal phase on estrous behavior and ovulatory follicle variables. Induction

Radiotelemetry of avian electrocardiogram

Medical & Biological Engineering & Computing, 1980
A radiotelemetry system has been developed which is capable of transmitting electrocardiogram signals from domestic fowl. The transmitter circuit consists of a frequency-modulated Colpitts oscillator operating at 104·5 MHz, followed by a single-ended amplifier. The devices are fabricated as thin-film hybrid microcircuits. Transmitters were encapsulated

Value of radiotelemetry in a community hospital

The American Journal of Cardiology, 1984
The use of radiotelemetry for continuous electrocardiographic monitoring of patients outside of special care units, although common practice in many community hospitals, has not been adequately studied. Two-hundred five consecutive patients placed on telemetry over a 3-month period were prospectively studied to determine the benefits of radiotelemetry.

An assessment of radiotelemetry in the monitoring of labour

BJOG: An International Journal of Obstetrics & Gynaecology, 1982
Summary. Conventional and telemetric monitoring of labour were compared in a randomized study of 200 patients to assess the effect on the pattern of labour, outcome and attitude of the patients. All the telemetry patients had the option of mobility, but only 45% elected to get out of bed, and then often only for short periods.

Combined telephone and radiotelemetry of the EEG

Electroencephalography and Clinical Neurophysiology, 1969
Abstract Multichannel local radiotelemetry of the EEG has been combined with onward transmission of the EEG data by telephone as frequency modulated audio subcarriers from the radio receiver located in the subject's house. Records are presented from a normal 10-year-old child, and are free from major artifacts. On-line spectral analysis was performed,

Pacemaker Malfunction With Radiotelemetry

JAMA: The Journal of the American Medical Association, 1971
To the Editor.— Electrical and radiofrequency devices have long been known to interfere with cardiac pacing and as such have represented potential hazards. 1,2 Lichter et al 3 reported two patients who had ventricular fibrillation when electric cautery was used to open the pericardium.

A Full-Duplex Radiotelemetry Transceiver

2021 5th International Symposium on Instrumentation Systems, Circuits and Transducers (INSCIT), 2021
A Full-duplex radio transceiver suitable for telemetry and sensor networks operating in the license-free ISM band at 27 MHz and capable of wirelessly transferring information and energy is presented. The transceiver’s analog blocks include a crystal oscillator, ASK modulator-demodulator, and LDMOS power amplifier.

Radiotelemetry of the Respiration of a Flying Duck

Science, 1962
Respirations of a flying wild mallard duck, Anas platyrhynchos , appear to be synchronized with wing beat in a ratio of 1 to 2. Wing beats come during exhalation and between respirations. The average number of respirations was 14 per minute for a resting duck and 96 per minute for a flying duck.
