ABSTRACT:
Arrangement for providing a boosted signal from a signal-generating device, such as a SAW device or an RFID tag, including an antenna and a circulator having a first port connected to the antenna to receive a signal therefrom and a second port connectable to the device to provide a signal thereto and receive a signal therefrom. The circulator amplifies the signal from the antenna and the signal received from the device such that a twice-amplified signal is directed to the antenna. A receiving and processing module transmits a signal to the antenna causing the antenna to generate its signal and receive a signal from the antenna derived from the twice-amplified signal. Various pumping systems for vehicle tires and electricity generating systems which generate energy upon rotation of a tire are also disclosed.
