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.

Claims

1. A wireless inline skate or skate board pulse watch comprising:

a first transmitter installed on the inline skate, said first transmitter comprising a vibration switch moved with the inline skate or skate board to output a voltage signal corresponding to the user'"'"'s foot motion, a CPU for processing data from the vibration switch of said first transmitter with encoder switches S0, S1, S2 thereof into a communication code signal, and a modulation and transmitting circuit which modulates the communication code signal, and a modulation and transmitting circuit which modulates the communication code signal from the CPU of said first transmitter into a radio inline skate or skate board signal and then transmits the radio signal thus obtained into the air;

a second transmitter secured to the user'"'"'s chest in front of the heart to detect the user'"'"'s heart rate, said second transmitter comprising a vibration switch vibrated with the beating of the user'"'"'s heart to output a voltage signal corresponding to the user'"'"'s heart rate, a CPU for processing data from the vibration switch of said second transmission with encoder switches S0, S1, S2 thereof into a communication code signal, and a modulation and transmitting circuit which modulates the communication code signal from the CPU of said second transmitter into a radio signal and then transmits the radio signal thus obtained into the air; and

a timer and display unit worn on the user'"'"'s wrist, said timer and display unit comprising a receiving and demodulation circuit, which receives the radio signals from said first transmitter and second transmitter unit and modulates the received signals into corresponding inline skate/skate board/hear rate pulse signals, a quartz vibrator, which provides a clock signal, a CPU, which counts the number of inline skate/skate board/heart rate pulse signals from said receiving and demodulation circuit and controls the operation of said quartz oscillator to count time, a timer switch, which is controlled to reset the CPU of said timer and display unit, and a display having a first display screen controlled by the CPU of said timer and display unit to display the data of the inline signal and a second display screen controlled by the CPU of said timer and display unit to display the data of heart rate pulse.

2. The wireless inline-pulse watch of claim 1 wherein said receiving and modulation circuit of said timer and display unit is comprised of a frequency variable inductance-capacitance resonance circuit, which is induced to output a corresponding signal upon receipt of a radio signal from said first transmitter unit or said second transmitter, an amplifier circuit, which amplifies the output signal from said resonance circuit, and a waveform rectifying circuit, which rectifies the output signal from said amplifier circuit into a square wave signal and outputs the square wave signal thus obtained to the CPU of said timer and display unit.
