Electronic tire management system
First Claim
1. A system comprising:
- a fuel depot to which a fuel consuming vehicle may be positioned to replenish its fuel store, the vehicle having a plurality of tires;
a sensor for sensing the operational characteristics of the tires of the vehicle;
a transceiver for transmitting information to the fuel depot;
a processor coupled to the sensor for activating the sensor on a first periodic basis, the processor periodically partially awakening to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakening and responding to the valid interrogation signal, via the transceiver, by transmitting at least one of the operational characteristics of the tires; and
a display viewable by a person located at the fuel depot for displaying the operational characteristics of the tires transmitted by the transceiver.

Abstract
An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor coupled to the sensor for activating the sensor on a first periodic basis to measure the device parameter. The microprocessor includes a memory for storing the generated data signal representing the measured parameter. A transmitter and a receiver are coupled to the microprocessor. The microprocessor periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter. In one embodiment, the device is a tire tag mounted inside a tire that measures tire data and transmits that data to a remote source in response to an interrogation request, an alert condition, or automatically on a periodic basis.

6. A vehicle comprising:
-
a plurality of tires;
a sensor for monitoring the operational characteristics of the tires;
a first transceiver associated with the vehicle for transmitting the monitored operational characteristics of the tires; and
a second transceiver associated with a display at the vehicle depot; and
a processor coupled to the first transceiver that periodically partially awakens and searches for a forward link packet from the vehicle depot and, if detected, causes the first transceiver to transmit the operational characteristics to the second transceiver, which routs information relating to the operational characteristics of the tires to the display. - View Dependent Claims (7, 8, 9)

10. A system comprising:
-
a display located at a fixed location;
a transceiver coupled to the display; and
a tire tag associated with a vehicle tire, the tag including a memory for storing characteristics of the tire, the tire tag periodically awakening to examine a transmission from the transceiver and to at least partially identify the transmission as an interrogation signal, the tag transmitting data representative of the tire characteristics to the transceiver in response to the interrogation signal, wherein the display displays the data. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for displaying the operational status of at least one tire of a vehicle when the vehicle moves proximate to a vehicle depot, comprising:
-
a sensor associated with one or more tires of the vehicle for monitoring the operational status of the tires;
a transceiver on the vehicle for transmitting data relating to the operational status of the tires;
a display located at the vehicle depot for viewing data relating to the operational status of the tires; and
a processor, for controlling the sensor and the transceiver, that periodically awakens and searches for a forward link packet from the vehicle depot and, if detected, causes the transceiver to transmit the data relating to the operational status of the tires. - View Dependent Claims (17, 18)
