ABSTRACT:
A device that measures the distance traveled, speed, and height jumped of a moving object or a person while running or walking. Accelerometers and rotational sensors are placed in the object or in the sole of one shoe, or in a wrist watch or the waist of the user, along with an electronic circuit that performs mathematical calculations to determine the distance and height. A microprocessor calculates an output speed based upon step-distance and elapsed time, and the distance traveled from the sum of all previous steps. The output of the microprocessor is coupled to a display that shows the distance traveled, speed, or height jumped.
