  • Method to calibrate a fiber optic strap on a body worn device
    Patent number: 9024750
    Abstract: The subject matter discloses a method and system for calibrating an electronic monitoring device having a housing and a strap being connected to a first end and a second end of the housing. The method provides for calibrating a transmission power level for signals transmitted along the strap. Then, the signal is generated and transmitted along the strap from the first end of the housing to the second end of the housing. Calibrating the transmission power level for signals transmitted along the strap provides for minimizing the power level to a lowest transmission power level detectable by a receiver located in the housing or until the signal is lower than a predefined threshold.
