TIRE INFLATION PRESSURE DETECTING APPARATUS CAPABLE OF TRIGGERING ONLY SELECTED TRANSCEIVER TO PERFORM TASK
First Claim
1. A transceiver comprising:
- a receiver that receives a trigger signal transmitted by a triggering device, the trigger signal indicating both a signal strength range and a command;
a signal strength determiner that determines strength of the trigger signal received by the receiver; and
a controller configured to;
determine whether the strength of the trigger signal determined by the signal strength determiner is within the signal strength range indicated by the trigger signal, andperform a task in accordance with the command indicated by the trigger signal only when the strength of the trigger signal is within the signal strength range.

Abstract
A transceiver according to the present invention includes a receiver, a signal strength determiner, and a controller. The receiver receives a trigger signal transmitted by a triggering device; the trigger signal indicates both a signal strength range and a command. The signal strength determiner determines the strength of the trigger signal received by the receiver. The controller is configured to: 1) determine whether the strength of the trigger signal determined by the signal strength determiner is within the signal strength range indicated by the trigger signal; 2) and perform a task in accordance with the command indicated by the trigger signal only when the strength of the trigger signal is within the signal strength range.

4. A wireless communication system for a vehicle, the system comprising:
-
first and second transceivers that are respectively located on first and second wheels of the vehicle, each of the transceivers being configured to; receive a trigger signal that indicates both a signal strength range and a command, determine strength of the trigger signal thereat, determine whether the determined strength of the trigger signal is within the signal strength range indicated by the trigger signal, and perform a task in accordance with the command indicated by the trigger signal only when the determined strength of the trigger signal is within the signal strength range; a triggering device that transmits the trigger signal, the triggering device being located on a body of the vehicle at different distances from the first and second transceivers, so that the strengths of the trigger signal at the transceivers are different from each other; a controller that is located on the body of the vehicle and configured to; select one of the first and second transceivers, set the signal strength range indicated by the trigger signal so that only the strength of the trigger signal at the selected one of the first and second transceivers is to fall within the signal strength range, and control the triggering device to transmit the trigger signal, thereby triggering only the selected one of the first and second transceivers to perform the task in accordance with the command indicated by the trigger signal. - View Dependent Claims (5, 6, 7)
