Abstract: Methods and devices are described for operating an input device for an electronic system which includes a housing. The input device includes an input surface and a first substrate having a first plurality of sensor electrodes configured to sense input objects proximate the input surface, and a pair of force sensing electrodes on the bottom of the first substrate. The input device includes a second substrate having a planar spring plate including a perimeter region surrounding an interior region, the perimeter region including a leaf spring coupled to the housing, and a spacing layer configured to physically couple the interior region of the second substrate to the first substrate. A force applied to the input surface deflects the first substrate and the interior region relative to the perimeter region, changing a variable capacitance formed between the force sensing electrodes.

Abstract: An input device may include a sensor substrate that including various sensor electrodes. The sensor electrodes may detect a location of one or more input objects. The input device may include a contact area coupled with the sensor substrate. The contact area may include a protective coating residue and a solder element array disposed on the contact area. The input device may include an electrical ground ohmically coupled to the contact area through the solder element array.

Abstract: An input device and method for use with an electronic system include a chassis having an interactive region; an input surface configured to deflect relative to the chassis in response to applied force, the input surface having a first region and a second region; and a processor communicatively coupled to the input surface and configured to disambiguate the first and second regions based on interaction between the input surface and the interactive region.

Abstract: A capacitive input device including a substrate, a first plurality of sensor electrodes disposed proximate a top surface of the substrate and extending along a first direction, a second plurality of sensor electrodes disposed proximate a bottom surface of the substrate and extending along a second direction different from the first direction, and a plurality of routing traces coupled to the second sensor electrodes. Each routing trace is configured to extend along the first direction between respective first sensor electrodes, and to extend along the second direction underneath a second sensor electrode.
