Speedometer for in-line skates
First Claim
1. A wireless apparatus for in-line skates comprising:
- an in-line skate having a skate unit disposed on the in-line skate, said skate unit having a wireless transmitter, a transducer and a processor, the processor processing a signal from the transducer into a digital data stream and the transmitter emitting a radio signal representing the digital data stream with a transmission signal strength reaching the upper regions of a skater'"'"'s body, anda remote receiver unit having a receiver and processor disposed in an upper region of a skater'"'"'s body, capable of receiving the digital data stream from the transmitter and displaying a visual representation of the data stream on an output device.

Abstract
An in-line roller skate includes a transducer portion capable of sensing the rotary movement of at least one wheel on the roller skate and transmitting information concerning the same to a receiver worn on a user'"'"'s wrist. In the preferred embodiment, the transducer portion includes a magnet attached to one of the plurality of wheels and a sensor positioned in a shoe portion to detect the magnet and produce electrical pulses containing information corresponding to the angular velocity of the wheel. The transducer portion also includes a micro-controller, a transmitter and an antenna. The micro-controller creates a digital data stream containing information corresponding to the angular velocity of the wheel, which is then modulated onto a carrier wave produced by the transmitter. The transmitter transmits the coded signals to the receiver. The receiver demodulates the carrier wave, reproducing the digital data stream. A microprocessor processes the modulated signals and drives the display to produce a real time visual representation of selected portions of information contained in the digital data stream, including speed and distance travelled by the skate.
