    摘要: A tamper detection monitoring apparatus and body. The monitoring apparatus includes a housing (14) having a first (15) and second (16) side, a light detector and a first connector (15a) on the first side, and a light emitter and a second connector (16a) on the second side. The monitoring apparatus further includes a strap (12) having a first end for coupling to the first connector and a second end for coupling to the second connector, wherein the strap contains an optical fiber. The monitoring apparatus further includes a first focusing lens disposed between the light detector and the first end of the strap and a processor configured to measure the variation in light received by the light detector.

    摘要: A tracking device, including a communication interface encased in a encasement with a receptacle on two opposite sides of the encasement, a strap, including one or more thin elongated flexible sheets, links coupled to one side of the one or more thin elongated flexible sheets, a fiber optic cable extending from a first end of the one or more thin elongated flexible sheets to a second end of the one or more thin elongated flexible sheets, a head connected to each end of the one or more thin elongated flexible sheets; wherein the heads are configured to fit into the receptacles and lock the strap in the receptacles thus preventing the strap from sliding out of the receptacles; and wherein the communication interface is configured to detect tampering with the strap by transmitting an optical signal through the fiber optic cable.
