An apparatus (5) can receive and transfer data and energy between adjacent apparatus (5) in a chain. Each apparatus (5) comprises an input antenna (10) for receiving an input signal (12) which is tuned and impedance matched (14) for a receiver and demodulator (40) in a control circuit (18). The demodulated signal is provided as input to a transmitter module (42) to create an output signal (34). The input signal (12) is then impedance transformed (20) to generate a sufficient voltage to energize a power supply (24) which charges a battery (26). The input signal (12) and the output signal (34) can be a radio signal, a magnetic induction signal, or a combined radio and magnetic induction signal. A controller (38) in the control circuit (18) monitors the condition of the battery (26) and power supply (24) and controls a switch (44) operable to selectively power parts of the apparatus (5) dependently upon their monitored condition. |
