ABSTRACT:
An ergometric exerciser of the constant work type using a mechanical to electrical transducer as its basis is described. The exerciser is controlled by a single chip microcomputer and associated electronic interfacing means to perform a multiplicity of selected functions. For example, the ergometric exerciser provides; adjustable work loading from 300 to 2100 kpm per minute; a flashing indicator light to warn of a low pedal speed; a pulse rate measurement from 40 to 200 beats per minute; a sonic pulse alert system adjustable from 60 to 200 beats per minute; an accurate electronic start/stop timer adjustable from 1:00 to 60:00 minutes; and a microcomputer controlled work computer which accurately calculates work done to a maximum of 99,990 kpm. All of the above functions can be conveniently performed by virtue of a control panel and visual display which is very easy to use to accurately and efficiently perform the above functions.
