20130076500COLLISION AVOIDANCE METHOD FOR TRANSMITTING DATA FROM MULTIPLE WIRELESS TIRE CONDITION SENSORS - A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.03-28-2013

20120235807DETECTING A TIRE ROTATION ON A TELEMATICS-EQUIPPED VEHICLE - A system and method for detecting a rotation of the vehicle tires between different wheel locations.

20090015393APPARATUS FOR DETECTING POSITIONS OF WHEELS OF VEHICLE AND APPARATUS FOR DETECTING TIRE INFLATION PRESSURE USING THE SAME - An apparatus for detecting positions of wheels of a vehicle is provided. In the apparatus, a triggering signal is transmitted from the body side to each transceiver mounted at each wheel. In each transceiver, the strength of the received triggering signal is measured and formatted into a frame of data to be transmitted to a receiver mounted to the vehicle body.

When no replay comes from the transceiver, the strength of noise is measured in the transceiver in response to a command from the receiver. When the noise strength is less than a threshold, the receiver commands an alarm member to issue alarm.01-15-2009
