1. A compound device having an interior volume and an exterior surface comprising:
- a wall located between the interior volume and an exterior of the compound device;
a protected component surrounded by an enclosure, said enclosure at least partially located in the interior volume;
a seal for closing said enclosure and isolating said protected component from said wall and for sealing the protected component from atmosphere;
an active area formed on at least a portion of the exterior surface;
a cover shielding said active area from said exterior; and
,a coupler attaching said seal to said cover, such that withdrawal of said coupler away from said active area synchronizes removal of said cover and unsealing of said enclosure.

Abstract
In accordance with some embodiments of the present invention there is provided a method of preparing a compound device for use. The device may include a sealed component and an active outer surface. The outer surface may be protected by a surface cover. Preparing the device may include activating the active outer surface by removing the surface cover and exposing an internal portion of the sealed component to the exterior of the device by unsealing the sealed component and synchronizing the activating and said unsealing using a coupler attached to the surface cover and the sealed component.

12. A method of preparing a device for use, the device including an active outer surface and a protected component isolated from a wall of the device and sealed from atmosphere by a sealed enclosure;
- the active outer surface protected by a surface cover and a coupler attaching said sealed enclosure to said cover, the method comprising;
withdrawing said coupler away from said active outer surface, and, in turn activating the active outer surface by removing the surface cover and exposing the protected component to the wall of the device by unsealing the sealed enclosure in a synchronized manner. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A compound device having an interior volume and an exterior surface comprising:
-
a wall located between the interior volume and an exterior of the compound device; a protected component surrounded by an enclosure, said enclosure at least partially located in the interior volume; an adhesive layer on at least a portion of the exterior surface; a surface cover shielding said adhesive layer from said exterior; a hard cap placed over the surface cover and being attached thereto; a seal for closing said enclosure, isolating said protected component from said wall and sealing the protected component from atmosphere; and
,a coupler attached to said seal, wherein withdrawal of said coupler away from said adhesive layer withdraws said seal from said enclosure and engages said seal with said hard cap, to, in turn, withdraw said hard cap away from said adhesive layer, thereby peeling the surface cover from the adhesive layer. - View Dependent Claims (20, 21, 22, 23)
