Abstract
Disclosed is an apparatus and methodology for providing a semi-passive transponder system in a vehicle. A semi-passive module employing backscatter technology is provided with an internal energy source that provides operating energy for at least a portion of the modules operating circuitry to reduce the energy requirements of a corresponding interrogator device. The module may be associated with tires mounted on a vehicle such that bi-directional communications may be established between the module and a centrally located interrogator module on the vehicle. The internal energy source may correspond to a battery, a fuel cell, a rechargeable device, an energy harvesting device, or similar devices.
