SYSTEM AND METHOD FOR DATA RETRANSMISSION THROUGH RF OPAQUE BARRIERS

摘要

A system and method for transmitting an information signal through a radio-frequency opaque barrier are disclosed. A transmitter is positioned on a first side of the barrier and a re-transmitter is positioned on a second side of the barrier. The transmitter includes a controller that modulates a received information signal with a carrier signal and forwards the modulated information signal to a vibration generator which converts the received electrical signal to a corresponding vibration signal. The re-transmitter includes an accelerometer that detects vibration signals and produces a corresponding electrical signal and a controller coupled to the accelerometer which receives the electrical signal from the accelerometer and demodulates the information signal included within the electrical signal received from the accelerometer. The transmitter may also include a vibration energy harvester which converts separate vibration signals received from the re-transmitter to energy that charges an energy storage device that powers the transmitter.

1. A system for transmitting a first information signal through a radio-frequency opaque barrier, comprising:
a transmitter positioned on a first side of and in close proximity to the radio-frequency opaque barrier, the transmitter comprising:
a vibration generator that converts an electrical signal received on an input to a corresponding vibration signal, anda controller that is coupled to the input of the vibration generator and which receives a first information signal, modulates the first information signal with a first carrier signal to produce a modulated first information signal, and forwards the modulated first information signal to the input of the vibration generator; and a re-transmitter positioned on a second side of and in close proximity to the radio-frequency opaque barrier, the second side of the radio-frequency opaque barrier opposite the first side thereof, the re-transmitter comprising:
an accelerometer that detects vibration signals and produces an electrical signal on an output corresponding to the detected vibration signals; anda controller that is coupled to the output of the accelerometer and which receives the electrical signal from the output of the accelerometer and demodulates the first information signal included within the electrical signal received from the output of the accelerometer.
