One-way travel computation detect device for exerciser

摘要

A one-way travel computation detector device for an exerciser having at least three sensors provided with an operation route of any movable exerciser wherein the sensors are equally spaced from one another. The sensors send feedback signals which are different from one another to facilitate signal identification by a central processor. A permanent magnetic wave transmitter is provided on a mobile part and has a working area capable of covering the entire exercise path. One way travel of the mobile part can be accurately computed upon acquiring of a one-way signal sequence from each of the sensors. The central processor accepts only a predetermined signal sequence.
