  • Patent number: 12026971
    Abstract: A sensor assembly includes a cover layer and a first sensor apparatus. The cover layer is molded from a first material to have a planar surface and non-uniform thickness, where a thickness of the first material at a first region of the cover layer is less than a thickness of the first material surrounding the first region. The first sensor apparatus is disposed beneath the planar surface of the cover layer, within the first region. The first sensor apparatus is configured to transmit and receive first capacitive sensing signals through a portion of the planar surface coinciding with the first region. For example, the first sensor apparatus may be a fingerprint sensor configured to detect a fingerprint on the portion of the planar surface coinciding with the first region based on changes in the first capacitive sensing signals.

  • Patent number: 11669167
    Abstract: The present implementations relate to a support structure for an input device that supports deflection of an input surface responsive to input forces exerted thereon and vibration of the input surface responsive to haptic feedback generated by a haptic actuator. The support structure includes one or more fixed structures mounted to a housing and a dynamic surface mounted to a sensor layer of the input device. A number of first deformable segments cantilever from the one or more fixed surfaces and deflect in a vertical direction when an input force is exerted on the sensor layer, where the input force is orthogonal to the input surface. A number of second deformable segments connect the plurality of first deformable segments to the dynamic surface and deflect in a horizontal direction when shear forces are exerted on the dynamic surface, where the shear forces are parallel to the input surface.
