Abstract: Some disclosed methods involve randomly or pseudo-randomly selecting one fingerprint authentication case from a plurality of fingerprint authentication cases stored in a memory, each of the fingerprint authentication cases corresponding to one or more fingerprints used during an authentication process, the fingerprint authentication cases including a plurality of multiple-fingerprint authentication cases for which two or more fingerprints are used during the authentication process. Upon determining that the selected fingerprint authentication case is a multiple-fingerprint authentication case, some methods involve controlling a display system to provide a multiple-fingerprint authentication graphical user interface (GUI) indicating at least two digit placement areas corresponding with a fingerprint sensor system area of a fingerprint sensor system, controlling the fingerprint sensor system to obtain fingerprint sensor data corresponding to each of the at least two digit placement areas and performing the authentication process based, at least in part, on the fingerprint sensor data.

Abstract: Systems and methods for detecting and mitigating a contaminant on a display are disclosed. In an aspect, a mobile device may scan the display. The mobile device may generate one or more images related to the contaminant based on the scanning. The mobile device may detect the contaminant on the display based on the one or more images. The mobile device may identify the contaminant on the display using the one or more images. The mobile device may perform a mitigation action to mitigate the contaminant based on the identification of the contaminant.

Abstract: Apparatuses, systems, and methods are provided for ultrasonic fingerprint sensors that feature an ultrasonic transmitter and multiple subsets of ultrasonic sensor pixels, each subset of ultrasonic sensor pixels associated with a different ultrasonically sensitive display surface, at least two of which are non-coplanar with one another. In some implementations, the ultrasonically sensitive display surfaces may be provided by different portions of a flexible display that has been flexed into a configuration in which two or more portions thereof are non-coplanar. In some instances, a controller may be provided that selectively reads ultrasonic sensor signals from subset(s) of the ultrasonic sensor pixels that are associated with the ultrasonically sensitive display surfaces that a touch-sensing system indicates are experiencing touch events.

Abstract: Methods, devices and systems for controlling an active fingerprint sensor area of a fingerprint sensor system are disclosed. In some examples, the one or more active fingerprint sensor area criteria may involve, or correspond to, a security level. The security level may correspond to a data security level, a software application security level, or a combination thereof. According to some examples, controlling the active fingerprint sensor area may involve activating a relatively larger fingerprint sensor area for a relatively higher security level. Alternatively, or additionally, the one or more active fingerprint sensor area criteria may correspond to a fingerprint sensor area used for obtaining fingerprint sensor data from one or more digits involved in an enrollment process, the size of one or more digits used during the enrollment process, the size of one or more digits used for one or more recent authentication attempts, or combinations thereof.

Abstract: Methods, systems, computer-readable media, and apparatuses for an authentication-based communication link with a peripheral device are presented. In some embodiments, the peripheral device receives, from a host device, and stores, in a memory of the peripheral device, registration data including, for instance, a user credential, a user identifier, and/or a device identifier. Upon a request to pair the peripheral device with the same or a different host device, the peripheral device requests and receives, from such a host device, authentication data including a user credential, a user identifier, and/or a device identifier. The peripheral device determines whether a match exists between the received authentication data and the registration data. If so, a communication link is established with the host device.

Abstract: Aspects generally relate to an apparatus for authenticating a user. The apparatus can include a screen, and located under the screen are a plurality of fingerprint scanners, the plurality of fingerprint scanners corresponding to respective regions of the screen. An interface requests a location of the screen that an application uses for a fingerprint scan. A screen location touched by a user is identified, and based on the screen location touched by the user and the location of the screen that an application uses for a fingerprint scan, enabling fingerprint scanners covering the region of the location of the screen.

Abstract: This disclosure provides systems, methods and apparatus for controlling a device operational mode. Some examples involve receiving an indication of an authentication attempt, determining an authentication mode corresponding with the authentication attempt and determining a device operational mode corresponding with the authentication mode. Responsive to determining that an authentication process corresponding with the authentication attempt completed successfully, a device operational mode corresponding with the authentication mode may be implemented. Examples of device operational modes include a limited access mode and a distress mode, both of which may involve blocking access to at least one type of device functionality or access to at least one type of data. The distress mode also may involve sending SOS data to one or more other devices. The quick launch mode may cause one or more selected software applications to initialize. Some authentication modes may involve obtaining fingerprint data from a specific combination of digits.

Abstract: Systems, methods, and non-transitory media are provided for managing thermal profiles for an electronic device. For example, a method may include setting an electronic device to first thermal profile based on a first context, receiving a context change indicating that the electronic device is associated with a second context and, based on the second context, setting the electronic device to a second thermal profile. The setting of the electronic device to the second thermal profile can occur in an interactive mode in which user input is received or a non-interactive mode in which the electronic device automatically selects the second thermal profile.

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.
