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: In some aspects, an electronic device may display a keyboard user interface on a touchscreen display panel. The electronic device may detect a key press interaction with the keyboard user interface. The electronic device may trigger one or more haptic actuators to generate a vibration waveform associated with a haptic pattern that is based at least in part on a context associated with the key press interaction. Numerous other aspects are described.

Abstract: Some disclosed methods may involve receiving an indication of a digit touching a surface of an apparatus in an active fingerprint sensor area, obtaining current fingerprint image data from the digit and performing a first authentication process based, at least in part, on the current fingerprint image data. Responsive to determining that the first authentication process is an unsuccessful authentication process, some methods may involve obtaining non-digit image data after the digit has been removed from the surface, performing a second authentication process based, at least in part, on the non-digit image data and providing a notification regarding the outcome of the second authentication process. In some examples, the non-digit image data may be obtained and the second authentication process may be performed without providing a notification regarding the unsuccessful outcome of the first authentication process.

Abstract: Some methods may involve receiving fingerprint image data and a first set of background image data from a fingerprint sensor and determining first processed fingerprint image data via a subtraction of the first set of background image data from the fingerprint image data. Some methods may involve obtaining force data corresponding to a force applied to the fingerprint sensor when the fingerprint image data were obtained. Some methods may involve obtaining a second set of background image data corresponding to the force data. Some methods may involve determining second processed fingerprint image data based, at least in part, on the first processed fingerprint image data and the second set of background image data, and outputting the second processed fingerprint image data. In some examples, determining the second processed fingerprint image data may involve a machine learning model. Some examples may involve estimating residual noise based on the force data.
