Abstract

A system and method for locally monitoring an orthopedic restraining device is provided. The restraining device restrains movement of a first flexibly connected body portion relative to a second body portion of an individual wearing the restraining device. Communication is accomplished by receiving a message signal from a restraining device controller operatively coupled to the personal orthopedic restraining device. The message signal is encoded into a display compatible signal. Subsequently, the display compatible signal is prepared for subsequent transmission by modulating the display compatible signal. Finally, the modulated display compatible signal is transmitted over a communication channel to the local monitoring unit such that the individual wearing the restraining device can receive messages from the restraining device controller. In addition, the operations of the local monitoring unit which displays a message from the restraining device controller based on contents of the display compatible signal are described.

7. A local monitoring unit, comprising:

(a) receiver means for receiving a modulated display compatible signal over a communication channel from a personal orthopedic restraining device controller;

(b) demodulator means, operatively coupled to the receiver means, for demodulating the received modulated display compatible signal into a display compatible signal; and

(c) video display means, operatively coupled to the demodulator means, for displaying a message from the restraining device controller based on contents of the display compatible signal.

8. The local monitoring unit of claim 7 wherein the communication channel is selected from the group consisting of an electronic data bus, radio communication link, wireline, and optical fiber link.

9. The local monitoring unit of claim 7 wherein the receiver means comprises means for receiving the modulated display compatible signal over a communication channel of a type selected from the group consisting of a serial port wireline, a parallel port wireline, an infra-red link, and a radio link.

10. The local monitoring unit of claim 7 wherein the message from the restraining device controller is selected from the group consisting of:
