Patent
Blood pressure and heart rate measuring watch
TL;DR: In this paper, a digital watch is employed to measure systolic and diastolic blood pressure as well as heart rate using a piezoelectric transducer that is held in contact with the wrist adjacent to the radial artery.
Patent
Portable blood pressure measuring device and method of measuring blood pressure
TL;DR: In this paper, a continuous blood pressure monitoring device includes a transducer mounted to detect arterial wall movement caused by blood flow through an artery of the user and means for measuring the output signals of the transducers and accurately converting these signals to systolic and diastolic blood pressure readings on a continuous basis.
Journal ArticleDOI
A Beat-to-Beat Heart Rate Meter
TL;DR: A new technique for computing beat-to-beat heart rate using a programmable counter is described, which is much less complex and consequently more economical than the circuits described elsewhere in the literature.
Journal ArticleDOI
A Precision Digital Instantaneous Heart Rate Meter with a Wide Range
TL;DR: A precision digital instantaneous heart rate meter with a wide range of 0-1023 beats/min was developed for converting the time interval between two successive heart beats to frequency and it has a wider range than other conventional tachometers.
Journal ArticleDOI
New Heat Rate Meter Based on Frequency Grading
L. Basano,P. Ottonello +1 more
TL;DR: A wide-range and high-resolution heart rate meter whose design is based on the automatic grading of the clock frequency, which allows a very efficient use of the memory capabilities of two suitably programmed EPROM's.

A wide-range linear beat-by-beat cardiotachometer.
Caldwell Wm,Smith Ld,Wilson Mf +2 more
TL;DR: A heart ratemeter operating over a range of 30–900 beats per minute has been designed, which is triggered from any measured cardiac variable to produce a linear d.c. beat-by-beat readout.

Journal ArticleDOI
An instantaneous heart-rate meter with digital display.
TL;DR: A portable battery-driven instrument is described which displays the instantaneous heart rate in digital form which no controls are required except the on/off switch and dry electrodes can often be used.
Journal ArticleDOI
Analogue-display rate meter built around digital switching elements.
TL;DR: This note describes a method of converting standard event pulses derived from a trigger into a rate output and a specific amplifier and trigger design are not considered.
