Abstract: An access control apparatus having a protective covering configure to cover at least one of a subject or an object inside said protective covering is provided, where an opening is configured to provide access to the at least one of a subject or an object and a covering element configured to selectively cover said opening. A receiving element is provided on the protective covering and an activating device with an activating element is provided external to the protective covering.

Abstract: The invention provides a retraining system that requires EM sensors, programmable computers and mechanical structures that are controlled by the programmable computers so that injured body parts of injury subjects are moved by the mechanical structures. The retraining methodology proposes the use of electromyograph (EMG) signals from a healthy subject having a healthy body part to control the mechanical structures that are coupled to the injured body parts of injury subjects. As part of the retraining system, the EMG signals of the same injured subject are also sensed by an EM sensor coupled to said injured subject in order to move the mechanical structures coupled to the injured subject. The system is calibrated to store in the programmable computers specific motions associated to the EMG signals of the healthy subject and to ensure that the EMG signals of the healthy subject and the EMG signals of the injured subject are significantly matched.
