    Abstract: The systems and techniques described herein generally relate to an electronic device having a touch-sensitive surface or region that is configured to receive force-based user input and dynamically adjust a force threshold used to recognize the force-based user input. In particular, the device may include one or more force sensors that are configured to detect a touch that exceeds a dynamically adjustable threshold. In some embodiments, the threshold is dynamically adjusted in response to a detected or estimated stability condition. By dynamically adjusting the threshold, the device may be better adapted or optimized for use with a particular support accessory or support configuration. In some cases, multiple sub-regions may be defined over the touch-sensitive surface, each sub-region having a different force threshold.

    Abstract: Various structures and methods are disclosed for packaging a biometric sensor, such as a capacitive biometric sensor. Embodiments incorporate various placements of the biometric sensor, structure surrounding a biometric sensor, connection structures (electrical, physical, or both), and techniques for enhanced sensor imaging, sensor retention, and guiding a user's finger to a proper location above a biometric sensor. For example, A biometric sensor assembly can include an aperture formed in a trim with a cap disposed in the aperture. A biometric sensor may be positioned below the cap and a switch positioned below the biometric sensor.
