Sensor stack venting
First Claim
1. An apparatus comprising:
- a pressure sensitive sensor stack having a plurality of layers that include one or more feature elements to implement accessory functionality provided by the apparatus;
one or more vent structures formed in the pressure sensitive sensor stack to convey gases released by the feature elements between the plurality of layers to designated escape points disposed in one or more of the plurality of layers; and
a designated vent layer configured to include the designated escape points to handle the gases that are conveyed to the designated vent layer via the vent structures from at least one other layer of the plurality of layers.

Abstract
Sensor stack venting techniques are described. In one or more implementations, one or more vent structures are formed within layers of a pressure sensitive sensor stack for a device. Vent structures including channels, holes, slots, and so forth are designed to provide pathways for gas released by feature elements to escape. The pathways may be arranged to convey outgases through the layers to designated escape points in a controlled manner that prevents deformities typically caused by trapped gases. The escape points in some layers enable at least some other layers to be edge-sealed. Pathways may then be formed to convey gas from the edge-sealed layer(s) to an edge vented layer(s) having one or more escape points, such that feature elements in the edge-sealed layer(s) remain protected from contaminants.

12. A method comprising:
-
forming vent structures within one or more of a plurality of layers of a pressure sensitive sensor stack including formation of designated escape points in at least one of the plurality of layers; and assembling the pressure sensitive sensor stack to align the formed vent structures to produce pathways across multiple layers of the plurality of layers for gases released by feature elements such that the gases from the feature elements disposed in the plurality of layers are conveyed via the vent structures within the plurality of layers to the designated escape points. - View Dependent Claims (13, 14, 15, 16)

17. An computing device comprising:
-
a pressure sensitive sensor stack having a plurality of layers including; a sealed layer having one or more feature elements; a vented layer of the plurality of layers with one or more escape points exposed to an exterior of the pressure sensitive sensor stack to allow gases to escape, the escape points including edge vents spaced along an edge of the vented layer; and one or more vent structures formed in the plurality of layers to facilitate conveyance of the gases released by the feature elements in the sealed layer to the escape points in the vented layer. - View Dependent Claims (18)
