Abstract: A massaging apparatus comprises a pair of massaging wheels obliquely and eccentrically attached to a main shaft, a shifting mechanism for shifting the massaging wheels and main shaft in the direction of the length of a chair back rest or a bed, and a spacing changing mechanism for changing the spacing between the massaging wheels. The apparatus is designed to detect the position of the pair of massaging wheels and the spacing therebetween. It further comprises position selecting switches associated with the neck, shoulders, back and waist of the human body. When any one of these position selecting switches is operated, the shifting mechanism and the spacing changing mechanism as well as the rotative direction of the main shaft are automatically controlled in accordance with the detected shifted position and spacing of the massaging wheels.

Abstract: A method and apparatus for monitoring and digitally displaying primate heart rate and systolic blood pressure product information. The apparatus has a microprocessor programmed to respond to signals relating to heart rate and systolic blood pressure and provide a digital output of the current product information and a two minute average of the product information. Separate LED displays are used to present the current and two minute average product information. An audible alarm operates to alert the personnel caring for the patient in the event that the pulse rate and blood pressure product exceeds a selected level. Operator controls are operable to read the input values, silence the alarm, read the external preset trip point, read the internal power supply and reference voltages, and verify the operations of all segments of all digits.
