Tibor A Nappholz, Ronald C Bradbury, Bruce R Satchwell: Dual chamber heart pacer with improved ventricular rate control. Telectronics, Gottlieb Rackman & Reisman, February 7, 1984: US04429697 (51 worldwide citation)

A dual-chamber heart pacer whose ventricular pacing rate is closely matched to the physiological requirements of the patient. A "true" atrial rate is determined by counting over a 3-second interval the number of sensed atrial beats, including those which occur during atrial refractory periods. When ...

Tibor A Nappholz, David K Money, Stephen Swift, Ronald C Bradbury: Heart pacer end-of-life detector. Telectronics, Gottlieb Rackman & Reisman, May 15, 1984: US04448197 (24 worldwide citation)

A heart pacer in which the magnitude of the end-of-life test current source is programmable. This effectively allows the physician to program the condition which will control a switch-over to end-of-life operation. It also allows the physician to override end-of-life operation after it initially tak ...

Royden J W Lake, Ronald C Bradbury, Rainer Kunnemeyer: Fat depth measuring apparatus. Meat Research Corporation, University of New England, Thomas M Freiburger, May 28, 1996: US05520183 (15 worldwide citation)

A fat depth measuring apparatus and method for use in measuring in an animal the depth of a fat layer between hide and muscle. An ultrasonic generator generates ultrasonic pulses and an ultrasonic echo detector generates echo signals indicative of ultrasonic pulses received by the detector after ref ...
