A wireless repeater system includes an antenna configured to receive a magnetic wake-up signal, a near field communication (NFC) receiver configured to receive a wake-up pattern and compare the received wake-up pattern with a stored wake-up pattern, and an NFC transmitter configured to transmit an output magnetic signal using the stored wake-up pattern to an external device, wherein the transmission of the output magnetic signal is synchronized with the received wake-up pattern to form a superimposed magnetic signal.

NFC repeater system

A device for reading magnetic information, having at least one read head including at least one magnetoresistive bar MR for generating data pulses representative of information read by the head. To enable the bar to be biased accurately without requiring a measurement of the quiescent resistance of the bar, the device includes a control loop for controlling the power dissipated in the magnetoresistive bar, the control loop having a time constant which is large with respect to the duration of the data pulses.
