Abstract

An embodiment of the present invention comprises a method of securing a room from removal of contaminants from the room, comprising a chamber and a portal with a door, wherein the method comprises: locking the door of the portal of the room; electronically sensing flesh of a hand of an occupant with a detecting device to determine if the flesh is exposed; automatically unlocking the door of the portal in response to electronically sensing the flesh in contact with the detecting device.

Claims

1. A method of securing a room from removal of contaminants from the room, comprising a chamber and a portal with a door, wherein the method comprises:

(a) locking the door of the portal of the room;

(b) electronically sensing flesh of a hand of an occupant with a detecting device to determine if the flesh is exposed;

(c) automatically unlocking the door of the portal in response to electronically sensing the flesh in contact with the detecting device.

2. The method of claim 1, wherein the step of electronically sensing further comprises electronically sensing at least one hand.

3. The method of claim 2, wherein the step of electronically sensing at least one hand requires sensing the flesh of at least one finger tip of the hand.

4. The method of claim 3 wherein the step of electronically sensing at least one hand requires sensing the flesh of five fingertips of the hand.

5. The method of claim 1, wherein the step of electronically sensing further comprises electronically sensing two hands of the occupant to determine if flesh is exposed in both hands.

6. The method of claim 5, wherein the step of electronically sensing two hands requires sensing the flesh of at least one finger tip on each hand.

7. The method of claim 6, wherein the step of electronically sensing two hands requires sensing the flesh of five finger tips on each hand.

8. The method of claim 1, wherein the step of electronically sensing is performed by measuring the capacitance between the hand and a sensor.

9. The method of claim 1, wherein the step of electronically sensing the hand requires sensing the flesh of five finger tips of the hand.

10. The method of claim 1, wherein the door has a lock which is electronically triggered.

11. The method of claim 1, wherein a receptacle intended for glove disposal is provided.

12. The method of claim 1, wherein an emergency over-ride system is present that allows unrestricted egress in times in times of emergency.
