Abstract: Some disclosed methods involve controlling a fingerprint sensor system to scan a portion of a user's digit and obtaining fingerprint image data corresponding to the portion of the user's digit. Some such methods involve obtaining defect data identifying one or more defective areas corresponding to an active fingerprint sensor area and determining whether the defect data indicates one or more defective areas corresponding to a touched portion of the active fingerprint sensor area from which the fingerprint image data were obtained. Some such methods involve determining, responsive to determining that the defect data indicates one or more defective areas corresponding to the touched portion, whether fingerprint image data corresponding to the one or more defective areas can be rectified and, responsive to determining that the fingerprint image data can be rectified, rectifying the fingerprint image data corresponding to the one or more defective areas.

Abstract: Apparatuses, systems, and methods are provided for use with expandable displays. In some implementations management techniques and/or systems are provided that allow for access to expandable display functionality to be managed to as to potentially prolong device battery life. In other or additional implementations, techniques and/or systems are provided for potentially safeguarding devices with expandable displays from damage in the event of a fall or drop event. In yet other or additional implementations, techniques and/or systems are provided for determining the expansion state of an expandable display, thereby allowing corrective measures to be taken if the actual expansion state of the expandable display does not align with the expected expansion state of the expandable display.

Abstract: Some disclosed methods involve controlling a fingerprint sensor system to scan a portion of a user's digit on a surface of an apparatus using a plurality of trial fingerprint sensor system parameters and selecting, from among the trial fingerprint sensor system parameters, one or more personalized fingerprint sensor system parameters for inclusion in a set of personalized fingerprint sensor system parameters. Some disclosed methods involve selecting, based on the one or more personalized fingerprint sensor system parameters, an existing fingerprint sensor system parameter data structure that includes a set of existing fingerprint sensor system parameters, obtaining additional fingerprint sensor system parameters from the set of existing fingerprint sensor system parameters for inclusion in the set of personalized fingerprint sensor system parameters, and storing the set of personalized fingerprint sensor system parameters for future scans of the fingerprint sensor system.

Abstract: Some disclosed methods involve controlling, via a control system of an apparatus, a touch sensor system to obtain touch sensor data in a touch sensor system active area of the apparatus. Some disclosed methods involve controlling, via the control system, a fingerprint sensor system of the apparatus to obtain fingerprint sensor data in a fingerprint sensor system active area of the apparatus. Some disclosed methods involve determining, via the control system and based on the touch sensor data, n touch locations corresponding to n last user touches and controlling, via the control system, a size of the touch sensor system active area based, at least in part, on the n touch locations.

Abstract: Apparatuses, systems, and methods are provided for ultrasonic fingerprint sensors that are able to be used to detect fingerprints from opposing sides of an apparatus, e.g., a smartphone with screens on both sides of the housing. Some implementations of such sensors may include, for example, two piezoelectric and sensor pixel layer assemblies coupled to a common controller. Other implementations of such sensors may include, for example, a single piezoelectric and sensor pixel assembly coupled with a controller configured to apply a range-gate delay to obtain fingerprint scans from either opposing side of an apparatus. Yet further implementations of such sensors may include acoustic masking layers to spatially filter ultrasonic waves propagating to either side of an apparatus.
