Abstract:

A system is disclosed that can measure the vertical height and/or the hang time of a jump. The system includes an acceleration detector, a controller, a display, a power source and a case that houses the components in a manner that allows the device to be worn or held by a person or object. The acceleration detector is used to determine the start of a jump and the end of a jump. Based on the time elapsed between the start of the jump and the end of the jump, the controller can determine the vertical height of the jump and/or the hang time.
