Abstract

A portable electronic device comprises an electromechanical module having an actuator for positioning a mechanical element between first and second positions, and a controller coupled to the electromechanical module. The controller is configured to detect a mechanical event coupling to the electromechanical module, select an actuation signal to position the mechanical element in a safe position between the first and second positions, and transmit the selected signal, such that the mechanical element is positioned in the safe position during the event.

Claims

1. A battery assembly comprising:

a battery element for storing electrical energy;

a battery case comprising first and second casing portions formed about the battery element, the first and second casing portions defining first and second major surfaces of the battery case;

a seal structure for sealing the battery case about the battery element, the seal structure comprising a bond between the first and second casing portions, the bond extending along a side of the battery case, the side extending between the first and second major surfaces;

a fold in the seal structure, wherein the fold positions the seal structure against the side of the battery case in a substantially perpendicular orientation with respect to the first and second major surfaces;

a protective wrap positioned about the battery case;

a first adhesive detachably coupling the protective wrap to the battery case and having a first bonding strength; and

a second adhesive detachably coupling a first portion of the protective wrap to a second portion of the protective wrap and having a second bonding strength greater than the first bonding strength.

2. The battery assembly of claim 1, further comprising a third adhesive provided along the side of the battery case, wherein the third adhesive retains the seal structure against the side of the battery case in the substantially perpendicular orientation with respect to the first and second major surfaces.

3. The battery assembly of claim 1 further comprising an insulating layer formed over an exposed end of the seal structure.

4. The battery assembly of claim 1, wherein the protective wrap provides a compressive coupling to retain the seal structure in the substantially perpendicular orientation along the side of the battery case.

5. The battery assembly of claim 1, further comprising a color-coded tab configured to detach the protective wrap by overcoming a bonding force of the first and second adhesives.

6. The battery assembly of claim 4, wherein the protective wrap comprises a cutout configured to space an edge of the protective wrap from a connector of the battery assembly.

7. The battery assembly of claim 4, wherein the protective wrap comprises a transparent portion to view an indicia on the battery case.

8. The battery assembly of claim 1, further comprising a second seal structure formed by a second bond between the first and second casing portions, the second bond extending along an opposite side of the battery case, wherein a second fold positions the second seal structure in the substantially perpendicular orientation along the opposite side.

9. A portable electronic device comprising the battery assembly of claim 1.
