Abstract: A system and method for communicating an orthopedic parameters signal between a remote communication unit and a central site monitoring station is provided. The orthopedic signal includes a value representative of a total torque output by an individual over a period of time as measured by a personal orthopedic restraining device. The restraining device is restrains movement of a first flexibly connected body portion relative to a second body portion. Communication is accomplished by receiving the orthopedic parameters signal at the remote unit from the orthopedic device. Subsequently, the received signal is protected from potential transmission errors through encoding. The encoded signal is prepared for transmission through modulation. Finally, the modulated signal is transmitted over a communication channel from the remote unit to the central station such that movement of flexibly connected body portions can be monitored. In addition, the operations of the central site monitoring station are described.

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.

Abstract: A method and apparatus is provided to facilitate coherent communication in a random access channel. In encoding, reference symbols are inserted into a stream of access channel message data symbols and appended to a synchronization message to form a reference coded access channel transmission. Subsequently, the access channel transmission is prepared for transmission over a communication channel by being spread with a spreading code. In decoding, a known synchronization sequence is correlated with a received communication signal to generate a correlation peak when a synchronization message is present. The received communication signal is despread with a spreading code to derive a stream of reference samples and data samples. A channel response is determined from the correlation peak and revised based on estimates derived from the stream of reference samples. Finally, an estimated data symbol is detected from the stream of data samples by utilizing the revised channel response.
