  • Patent number: 12008836
    Abstract: This document describes systems and techniques for spatially and temporally dynamic illumination for fingerprint authentication. In aspects, a method is disclosed that involves receiving user input at a display of an electronic device, initiating biometric authentication, and instructing a display-driver integrated circuit (DDIC) to implement a local high-brightness mode, which causes a predetermined portion of the display to increase in luminance to a target luminance for at least a first interval and a second interval. The DDIC is also instructed to cause a variable portion of the display to increase in luminance for the first interval and, at the expiration of the first interval, decrease luminance. During the first and/or second interval, an under-display fingerprint sensor captures one or more images. It is then determined, based on analysis of the one or more images, whether the user input is indicative of an authorized user.

  • Patent number: 12003671
    Abstract: Voicemail spam detection is performed based on content of voicemail messages. The content of an incoming voicemail message is compared to a spam template that includes a representation of a spam voicemail. Spam templates may be generated based on spam indications provided by users for voicemail messages they have received. User indications for sufficiently similar voicemail messages may be aggregated by maintaining a vote count for a spam template that reflects how many times a user has indicated a matching voicemail message is spam. A spam template may also include an occurrence count that reflects how many times voicemail messages matching a spam template have been detected in a telephony system. An incoming voicemail message may be compared to spam templates and, responsive to a match of content and/or a corresponding vote count or occurrence count meeting a condition, the voicemail message may be identified as spam.

  • Publication number: 20240177687
    Abstract: Techniques and apparatuses are described that perform frequency compensation for a display. In aspects, a first uniformity of multiple regions of the display can be measured at a reference frequency. The display can then be driven at a second frequency and a second uniformity of the multiple regions of the display can be measured. The differences between the first and second uniformity can then be used to generate a compensation mask. XYZ domain data from the first and second uniformity measurements can be used to generate a color model characterization. The color model characterization can be used to convert the XYZ domain data into RGB data when the display is driven at the second frequency to compensate for the differences in uniformity across the multiple regions of the display.

  • Publication number: 20240163400
    Abstract: A transcript of a conference (e.g., a video conference, an audio conference, or a telephone call with two or more participants) is processed to extract a conference summary. The transcript includes strings that are associated with respective timestamps and respective speaker identifiers. Speaker segments—sequences of consecutive strings attributed to the same speaker—are identified in the transcript. A speaker segment is selected based on its duration in time and one or more strings are selected from with the selected speaker segment for inclusion in the conference summary. A short video conference summary or a short audio conference summary is then generated using timestamps from the transcript associated with strings (e.g., sentences) that have been selected for inclusion in the conference summary. The short video or audio summary may be presented to users to enable efficient storage and transmission of information from the conference within a unified communications system.

  • Publication number: 20240135854
    Abstract: A method involves measuring, for an optical property of the display panel for an input gray level and at a first refresh rate, first and second values at respective first and second ambient brightness levels. The method also involves determining a compensation factor for the input gray level at the first refresh rate. The method further involves determining a modified gamma value at a second refresh rate, wherein the modified gamma value reduces a perceived optical defect of the display panel when operating at the second refresh rate by maintaining a consistent delta difference in values for the optical property between the first and second refresh rates at different ambient brightness levels. The method additionally involves storing the modified gamma value, where the device is configured to adjust input display data using the modified gamma value when transitioning from the first refresh rate to the second refresh rate.
