Abstract
A device is provided for sensing a condition of a non-rotating pneumatic tire preferably of the type used on an automobile wherein the tire is mounted on a tire rim. The device comprises a housing, a band for mounting the housing to the tire rim, a sensor for monitoring the condition within the tire, circuitry operatively connected to the sensor for generating radio signals indicative of the tire condition, a power supply operatively connected to the circuitry, an externally controlled switch, and a receiver for receiving the radio signals. The externally controlled switch is manually or electromagnetically operable to cause the condition sensor to generate radio signals when the pneumatic tire is stationary. A method of mathematically cross-linking data and identification information is provided to ensure data integrity. Also, the system includes a data logging capability for storing time series tire condition information for use as a historical log of tire use. Predictive capabilities retrieve manufacturer's specifications stored in a memory for comparison against real time use data to predict or otherwise anticipate possible hazardous conditions or tire life expectancy.
