ABSTRACT:
A wireless inline skate or skate board pulse watch which includes an inline skate or skate board transmitter worn on the user's foot to detect his body motion through a vibration switch and to moderate the detected signal into a radio signal is described. The watch further includes a heart rate pulse signal transmitter secured to the user's chest to detect his heart rate through a vibration switch and to modulate the detected signal into a radio signal. A timer is also provided, and a display unit which is worn on the user's wrist to receive and demodulate the output signals of the transmitters to show the data of speed/distance of the user's body motion and the number of beats per second of the user's heart through two separate display screens.
