Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products for indicating a reference song. A computing device stores reference song characterization data that identifies a plurality of audio characteristics for each reference song in a plurality of reference songs. The computing device receives digital audio data that represents audio recorded by a microphone, converts the digital audio data from time-domain format into frequency-domain format, and uses the digital audio data in the frequency-domain format in a music-characterization process. In response to determining that characterization values for the digital audio data are most relevant to characterization values for a particular reference song, the computing device outputs an indication of the particular reference song.

Abstract: Described is a technique for optimization an image for facial detection. More specifically, described is a process of predicting the location of a face within an image and adjusting image settings based on at least a portion of the predicted location of the face. An image may be adjusted based on the characteristics of a metering region, which may be selected prior to performing facial detection. For example, the metering region may be a specified shape with dimensions equal to a certain percentage of the input image and placed at a specified location. The result of using such a metering region is that the image adjustments may be based on a portion of the face, and therefore, may be optimized for facial detection.

Abstract: Apparatus, systems, methods, and computer program products are disclosed for providing software updates to client devices.

Abstract: Techniques and apparatuses are described that enable radar attenuation mitigation. To improve radar performance, characteristics of an attenuator and/or properties of a radar signal are determined to reduce attenuation of the radar signal due to the attenuator and enable a radar system to detect a target located on an opposite side of the attenuator. These techniques are beneficial in situations in which the attenuator is unavoidably located between the radar system and a target, either due to integration within other electronic devices or due to an operating environment. These techniques save power and cost by reducing the attenuation without increasing transmit power or changing material properties of the attenuator.

Abstract: Aspects of the technology implement a authenticating protocol that enables a Trusted Provider to vouch for a requesting entity when that entity seeks verification from an authenticating entity (FIG. 1). This is done without sharing the requesting entity's confidential or other personal information directly with the authenticating entity (FIG. 1). Instead, the Trusted Provider is able to use specific information about a requesting entity, such as contact information that forms an identity record (404), and generate a hash of the record (408). The hash is sent to an authenticating entity (410), which returns a secure token to the Trusted Provider (508). The secure token and identity record information are used to create a verification URL (414), which is shared with the requesting entity (416). The verification URL, when clicked, links back to the authenticating entity (FIG. 1), which validates the requesting entity (512, 514).

Abstract: Instead of accepting competing ads and using an arbitration function (e.g., an auction) to choose winning ads to be served with a document, sets of ads (perhaps having different characteristics) can be generated, and an arbitration function can be used to select the winning set of ads. Such arbitrations on sets of ads can consider how ads, search results, colors, positions, fonts, etc., all interact with each other and affect the usefulness of the sets of ads to advertisers, end users, document publishers, and/or an ad serving entity.

Abstract: Systems and/or methods provide a user of a first computing device with the ability to authenticate themselves on a remotely provided process or service using a second computing device on which the user is already authenticated. For example, the techniques of this disclosure provide a user with the ability to securely log into a remotely provided service or application (such as e-mail, cloud computing service, etc.) on a first computing device (e.g., a desktop computer, laptop, tablet, etc.) using a second computing device (e.g., mobile phone) on which the user is already logged into the service or application, without requiring manual entry of authentication information on the first computing device.

Abstract: This document describes techniques and systems that enable a radar-image shaper for radar-based applications. A radar field enables an electronic device to accurately determine a characteristic disposition (e.g., a location, orientation, velocity, or direction) of an object in the radar field. The characteristic disposition is determined by detecting a radar cross-section (or radar signature) of a radar-image shaper that is included in the object. The shape of the radar-image shaper produces a known signature when illuminated by the radar field. Using these techniques, the electronic device can determine a characteristic disposition of the object, which allows the object to be used to interact with the electronic device using gestures and other position-based techniques. Because the radar-image shaper enables a passive object to control applications on the electronic device, users have an interaction method with a rich library of gestures and controls that does not require additional components or a battery.

Abstract: An originating server of a payment processing system comprising multiple communicating servers first processes a transaction event, generates a correlating identifier and transmits the correlating identifier and processing information to a central data log accessible by the multiple communicating servers. One or more intermediate servers and a terminating server then process the transaction event, each successive intermediate server and the terminating server receiving the transaction event and a correlation identifier associated with the transaction event generated by the previous server which processed the transaction event. Each successive intermediate server and the terminating server generates a correlation identifier, and transmits both the received and generated correlation identifiers to the central transaction log. A query comprising a correlation identifier associated with the transaction event is received.
