  • Remotely activated retractable reel prisoner control system
    Patent number: 6368262
    Abstract: A prisoner control harness has a retractor reel with a cord leading to a cuff worn at one of the prisoner's extremities. Engageable ratchet means are provided for limiting the motion of the retractor reel and remote control means under the control of a custodian or guard, are provided for activating the ratchet so that if the custodian needs to disable the prisoner, a signal from the remote control activates the ratchet so that the cord reels in but will not reel out, limiting the prisoner's ability to escape.
