<div class="section abstract"><div class="htmlview paragraph">ABSTRACT</div><div class="htmlview paragraph">A new magnetic circuit design for the Wiegand Effect has resulted in a rugged, stable transmission-mounted speed signal generator to provide a digital speedometer/odometer readout, and to provide an input for microprocessor vehicle management systems. The device requires no electrical input, and delivers a uniform signal at TTL level from zero speed. It can directly replace existing flexible cable drives.</div></div>
