ABSTRACT:
A system with a self-powered sending unit communicating with a receiving unit. The sending unit interacts with a magnet attached to a rotating or moving member. The sending unit includes an inductor that intercepts the magnetic field from the magnet. The magnetic interaction with the sending unit generates power that is stored for later use by a transmitter. The magnetic interaction also provides a trigger for the transmitter that causes the transmitter to send a signal using the stored energy. In one embodiment, the signal includes a identification code that uniquely identifies the sending unit. A receiving unit includes a receiver responsive to the transmitted signal and, in one embodiment, a display of the measured parameter that is projected by a heads-up display unit.
