1. A wheel unit comprising at least:
- an environmental sensing component configured to measure at least one parameter indicative of at least one environmental condition within or of a tire,a non-volatile memory configured to store a first program, a second program, and configuration code,a processing unit configured to control the wheel unit and configured to execute at least one of the first program and the second program,a wheel unit communication module further comprising;
a wireless transmitter configured to transmit at least tire condition related information anda receiver configured to receive at least one of the first program, the second program, and the configuration code, the receiver being wireless or wired,wherein the first program comprises a first upload manager operably cooperated with the wheel unit communication module to receive and load into the non-volatile memory the second program,wherein the second program is adapted to use the first upload manager to receive the configuration code or comprises a second upload manager to receive the configuration code, andwherein the configuration code is adapted to provide information about at least one tire-pressure monitoring (TPM) system to the second program;
wherein the information is adapted to be used by the second program to configure the behavior of the wheel unit so as to adapt the wheel unit to operate according to requirements of the at least one TPM system.

Abstract
A wheel unit including an environmental pressure sensor, a non-volatile memory for storing a first program and a second program and configuration code, a processing unit for executing the programs, a communication module comprising a wireless transmitter for transmitting at least one parameter indicative of conditions within a tire and a wireless or wired receiver for loading the second program into the non-volatile memory and a battery for powering the wheel unit. The second program may be loaded to the memory by the first program and configured by the configuration code to operate within a specific TPM system.
