Tire condition detecting system for wheeled vehicle
First Claim
1. A wheeled vehicle comprising a frame assembly, at least one wheel coupled to the frame assembly, the wheel including a rim and a tire mounted on the rim, a sensor detecting a condition of the tire and generating a signal indicative of the condition of the tire, a transmitter transmitting the signal at various transmission intervals, a receiver receiving the signal from the transmitter, and a controller controlling the transmitter, the controller determining the transmission intervals based upon the signal.

Abstract
A wheeled vehicle includes a tire condition detecting system in which a sensor (or possible a plurality of sensors) of the system detects one or more tire conditions (e.g., pressure and/or temperature) of at least one wheel of the vehicle. A transmitter transmits a signal indicative of the tire conditions sensed by the sensor at various transmission intervals. A receiver located on a frame assembly of the vehicle receives the signals from the transmitter. A controller is provided to control the transmitter. The controller determines the transmission intervals based upon the tire condition signal(s) sent by the sensor(s) so as to reduce power consumption by the system when possible. A rechargeable power source preferably powers at least the transmitter or the controller. The power source can be recharged using a hole in a rim of the wheel.
