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: In some implementations, a method may involve detecting that touch sensing using a capacitive touch sensor system is inoperable in a given user context. Touch sensing using the capacitive touch sensor is disabled and touch sensing using an alternative sensor system is enabled. The alternative sensor system may include a fingerprint sensor system, an optical sensor system, and a force sensor system. Touch sensing using the alternative sensor system may be limited to a designated portion in a graphical user interface for improved user experience. In some implementations, the designated portion may be coextensive with an active area of the fingerprint sensor system and user interface controls may be arranged into an array of tiles.

Abstract: In some implementations a method may involve presenting a graphical user interface in a first configuration on a display of an apparatus. The first configuration may correspond with a first display area. The method may involve enabling operation of a fingerprint sensor system in a first fingerprint sensor area corresponding with at least a portion of the first display area. The method may involve presenting the graphical user interface in a second configuration on the display and enabling fingerprint sensor system operation only in a second fingerprint sensor area corresponding with the second configuration.

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: Methods, devices and systems for controlling a fingerprint sensor system are disclosed. Some examples involve receiving a contact indication corresponding to a contact of an object with a surface of an apparatus and determining, responsive to the contact indication, multiple force values corresponding to contact of the object with the surface during a force monitoring time interval. Some examples involve determining whether at least a plurality of the multiple force values exceeds a force threshold and controlling a fingerprint sensor system based, at least in part, on whether at least the plurality of the multiple force values exceeds the force threshold.

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.
