Input device securing techniques
First Claim
1. An input device comprising:
- a sensor substrate having a first set of one or more conductors of a first pressure sensitive key and a second set of one or more conductors of a second pressure sensitive key;
a spacer layer disposed proximal to the sensor substrate and having first and second openings that expose the first and second sets of conductors, respectively; and
a flexible contact layer spaced apart from the sensor substrate by the spacer layer and configured to flex through the first and second openings responsive to an applied pressure to contact, respectively, the first and second sets of conductors to initiate respective first and second inputs, in which an arrangement of adhesive that secures the flexible contact layer to the spacer layer along one or more edges of the first opening corresponding to the first pressure sensitive key is different than an arrangement of adhesive that secures the flexible contact layer to the spacer layer along one or more edges of the second opening corresponding to the second pressure sensitive key, the arrangements including discrete portions of applied adhesive, and defining portions along the edges of the openings corresponding to the first and second pressure sensitive keys, respectively, that do not include adhesive.

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.

12. An input device comprising:
-
a sensor substrate having a plurality of conductors that support a plurality of pressure sensitive keys; a spacer layer disposed proximal to the sensor substrate and having openings that expose the plurality of conductors of the plurality of pressure sensitive keys, respectively; and a flexible contact layer spaced apart from the sensor substrate by the spacer layer and configured to flex through the openings responsive to an applied pressure to contact respective said conductors of the respective said keys, in which arrangements of adhesive along edges of the openings that secures the flexible contact layer to the spacer layer varies for first and second said pressure sensitive keys, one to another, the arrangements including discrete portions of applied adhesive, and defining portions along edges of the openings corresponding to the first and second said pressure sensitive keys, respectively, that do not include adhesive. - View Dependent Claims (13, 14, 15, 16, 17, 18)
