Abstract:
An input device for fingerprint sensing and proximity sensing includes a cover layer, where a top surface of the cover layer is configured to provide an input surface for a finger, a substrate having a cavity disposed below the cover layer, and a fingerprint sensor disposed below the cover layer and in the cavity of the substrate. A first adhesive layer is disposed between a top surface of the fingerprint sensor and a bottom surface of the cover layer in a fingerprint sensing area. A second adhesive layer is disposed between a top surface of the substrate and the bottom surface of the cover layer in a proximity sensing area.
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:
A key assembly is for use in a keyboard of the type including a key guide having a planar translation effecting (PTE) feature. The key assembly includes a key base having a PTE mating feature configured to interact with the PTE feature during a key press, and a key cap configured to be attached to the key base. The key base is made of a first material and the key cap is made of a second material different from the first material. A conductive portion and/or a magnet may be wedged between or secured within the key base or the key cap.
