Abstract
An electronic pedometer to accurately measure stride length of a walker includes a processing unit with an ultrasonic sound wave receiver attached to one foot and an ultrasonic sound wave generator attached to the other foot. Pressure sensitive switches close when each foot makes a step, providing signals to the processing unit to record the number of strides. The processing unit computes stride length by calculating distances using the ultrasonic sound waves.
