Abstract: Methods and electronic devices are provided in which first fingerprint information of a first portion of the user's fingerprint is obtained upon the user's fingerprint contacting the fingerprint sensor. A display object is output within a target area for the fingerprint registration, in response to obtaining the first fingerprint information.

Next fingerprint information of the next portion of the user's fingerprint is obtained upon the user's fingerprint contacting the fingerprint sensor guided by the guiding object. Upon modifying the display object based on the obtained next fingerprint information, the steps of outputting a guiding object and obtaining a next fingerprint information are repeated until fingerprint information at least partially surrounding the first portion is obtained.

Abstract: An electronic device includes a processor, and a memory containing instructions that, when executed by the processor, cause the electronic device to learn a sound emitted by a legacy device and to issue an output when the electronic device subsequently hears the sound. For example, the electronic device can receive a training input and extract a compact representation of a sound in the training input, which the device stores. The device can receive an audio signal corresponding to an observed acoustic scene and extract a representation of the observed acoustic scene from the audio signal. The electronic device can determine whether the sound is present in the observed acoustic scene at least in part from a comparison of the representation of the observed acoustic scene with the representation of the sound. The electronic device emits a selected output responsive to determining that the sound is present in the acoustic scene.

Abstract: Systems and techniques for removing non-stationary and/or colored noise can include one or more of the three following innovative aspects: (1) detection of an unwanted target signal, or component thereof, within an observed signal; (2) removal of the target (component) from the observed signal; and (3) filling of a gap in the observed signal generated by removal of the unwanted target (component). Removal regions, frequency bands, and/or regions of the observed signal used to train the gap filler can be adapted in correspondence with local characteristics of the observed signal and/or the target signal (component).

And, a corrected signal in machine-readable form can be converted to a human-perceivable form, and/or to a modulated signal form conveyed over a communication connection.
