Input device securing techniques
First Claim
1. A key comprising:
- a sensor substrate;
a spacer layer disposed proximal to the sensor substrate and having at least one opening that exposes the sensor substrate, the opening defining a plurality of edges of the key; and
a flexible contact layer spaced apart from the sensor substrate by the spacer layer and configured to flex through the opening in response to an applied pressure to initiate an input through contact with the sensor substrate, the flexible contact layer secured to the spacer layer such that;
at a first said edge, the flexible contact layer is secured with adhesive to the spacer layer at one or more discrete portions of the first said edge thereby defining portions along the first said edge that do not include adhesive; and
at a second said edge, the flexible contact layer is secured with adhesive to the spacer layer at one or more discrete portions of the second said edge thereby defining portions along the second said edge that do not include adhesive, the one or more discrete portions of the first said edge different than the one or more discrete portions of the second said edge.

Abstract
Input device adhesive techniques are described. A pressure sensitive key includes a sensor substrate having one or more conductors, a spacer layer, and a flexible contact layer. The spacer layer is disposed proximal to the sensor substrate and has at least one opening. The flexible contact layer is spaced apart from the sensor substrate by the spacer layer and configured to flex through the opening in response to an applied pressure to initiate an input. The flexible contact layer is secured to the spacer layer such that at first edge, the flexible contact layer is secured to the spacer layer at an approximate midpoint of the first edge and is not secured to the spacer along another portion of the first edge and at a second edge, the flexible contact layer is not secured to the spacer layer along an approximate midpoint of the second edge.

10. An input device comprising:
-
at least one key; a sensor substrate; a spacer layer disposed proximal to the sensor substrate and having at least one opening that exposes the sensor substrate, the at least one opening defining a plurality of edges of the at least one key; and a flexible contact layer spaced apart from the sensor substrate by the spacer layer and configured to flex through the opening in response to an applied pressure to initiate an input through contact with the sensor substrate, the flexible contact layer secured to the spacer layer such that; at first said edge, the flexible contact layer is secured with adhesive to the spacer layer at one or more discrete portions of the first said edge thereby defining portions along the first said edge that do not include adhesive; and at a second said edge, the flexible contact layer is secured with adhesive to the spacer layer at one or more discrete portions of the second said edge thereby defining portions along the second said edge that do not include adhesive, the one or more discrete portions of the first said edge different than the one or more discrete portions of the second said edge. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
