System and method for tire pressure monitoring
First Claim
1. A system for monitoring at least one parameter of a tire of a vehicle, the system comprising:
- a receiver having a storage memory comprising a set of locally unique identifiers and a code, the receiver configured to;
receive a transmitted signal comprising an encrypted portion and a data portion;
decrypt the encrypted portion using at least one of the code and the locally unique identifiers to produce a decrypted portion;
determine if the decrypted portion matches one of the code and the locally unique identifiers; and
process the data portion when the decrypted portion matches one of the code and the locally unique identifiers; and
a transmitter corresponding to the tire and having a programmable memory storing the code and one of the set of locally unique identifiers, the transmitter configured to;
generate the encrypted portion based on the stored locally unique identifier and the code;
generate the data portion based on sensing the at least one parameter of the tire; and
transmit the transmitted signal comprising the encrypted portion and the data portion.

Abstract
A system for monitoring at least one parameter of vehicle tire includes a receiver and a transmitter. The transmitter corresponds to the tire and has a programmable memory storing a code and one of a set of locally unique identifiers. The transmitter generates an encrypted portion of a transmitted signal based on the locally unique identifier and the code. The transmitter generates a data portion of the transmitted signal based on sensing at least one parameter of the tire. The receiver stores a set of locally unique identifiers and the code. The receiver receives the transmitted signal. The encrypted portion is decrypted using at least one of the code and the locally unique identifiers to produce a decrypted portion. A check is made to determine if the decrypted portion matches one of the code and the locally unique identifiers and, if so, the data portion is processed.

9. A method for monitoring a vehicle tire comprising:
-
storing in a transmitter a locally unique tire identifier and a code, the transmitter associated with the monitored vehicle tire; generating an encrypted portion of a transmission signal based on the locally unique tire identifier and the code; generating a data portion of the transmission signal based on at least one parameter sensed for the vehicle tire; and transmitting from the transmitter the transmission signal. - View Dependent Claims (10, 11, 12, 13)

14. A method for monitoring a particular tire on a particular vehicle, the particular vehicle one of a plurality of vehicles, the particular tire one of a plurality of monitored tires on the plurality of vehicles, the method comprising:
-
assigning to the particular tire one of at least one locally unique identifiers, each locally unique identifier different from any other tire identifier associated with a receiver on the particular vehicle but not necessarily different from any other tire identifier associated with a different vehicle in the plurality of vehicles; assigning to the receiver a unique code; receiving in the receiver a transmission signal including an encrypted portion and a data portion; decrypting the encrypted portion using at least one of the code and at least one of the locally unique identifiers to generate a decrypted portion; comparing the decrypted portion with at least one of the code and the at least one of the locally unique identifiers and, if the comparison results in a match, processing the data portion. - View Dependent Claims (15, 16, 17, 18)
