Patent ID: 11466505

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. A motor is coupled to the covering element, wherein said motor selectively moves the covering element to at least partially unblock the opening based on a wireless activation signal and a distance between the activating element and the receiving element being within a predefined distance and to completely block the opening based on the wireless activation signal and the distance between the activating element and the receiving element being greater than the predefined distance, effectively limiting the exchange of contaminated or adverse environments between an internal area of the protective covering and an area outside the protective covering. The covering element can be an integral covering or an iris diaphragm arrangement.
