Abstract: Techniques are directed to identifying focus points of a body part of a user as alignment features for calibration verification. In some implementations, a body part of the user may be a hand, and the focus points are joints. A calibration verification involves, in some implementations, capturing an image of a user's hand and detecting the joints of the hand. The calibration verification then involves, in such implementations, determining distances between joints and computing a metric based on the distances. This metric is then compared to a ground truth metric and the calibration is evaluated based on the verification.

Abstract: Implementations receive, via a client device, user input to initiate a telephone call with an entity, and, in response to receiving the user input to initiate the telephone call with the entity and prior to initiating the telephone call with the entity: obtain pre-call information that is stored in association with the entity, and cause the pre-call information that is stored in association with the entity to be provided for presentation to the user via the client device. The pre-call information may include any information that would be provided for presentation to a user subsequent to initiation of the telephone call with the entity. Further, implementations determine, based on user consumption of the pre-call information, whether to (1) proceed with initiating the telephone call with the entity, or (2) refrain from initiating the telephone call with the entity, and cause the client device to implement the appropriate action.

Abstract: Aspects of the disclosure are directed to generating cache configurations for caching data for a database. A database management system (DBMS) can search for column data to cache in a database cache to improve performance of the DBMS in resolving queries. Column data selection can be performed automatically and in the background of a deployed DBMS. Periodically, the DBMS can assess the performance benefit of having certain data cached in the database cache and select data for caching based on the assessed performance benefit. The DBMS can also determine the performance benefit of cached data when not cached, as well as select some portions of data to cache over others. The DBMS can also select data for caching based on different degrees of compression, to further improve query resolution performance.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for processing local search results. In one aspect, a method determines a first local document in a set of local documents for search results is eligible for a demotion operation. The determination is based at least in part on a proximity measure based on the location of the user device and a location specified for the first local document. In response to the determination, for each other local documents in the set of local documents, a proximity measure location of the user device and the location specified for the other local document is determined. The first local document is demoted in its ranking when at least one of the proximity measures indicates a respective other local document has a specified location that is within a threshold distance of the location of the user device.

Abstract: A method includes receiving a build request containing build step instructions from a user.

Abstract: A method for a soft acceptance of a hotword receives audio data characterizing a soft hotword event detected by a hotword detector in streaming audio captured by a user device. The method also processes the audio data to determine that the audio data corresponds to a query specifying an action to perform on the user device. Without triggering performance of the action on the user device or the other device, the method provides a notification for output from the user device where the notification prompts a user associated with the user device to provide an affirmative input indication in order to trigger performance of the action on the user device or the other device and, when the user fails to provide the affirmative input indication, instructs the user device or the other device to not perform the action specified by the query.

Abstract: A new reference framework is described that ranks reference frames based on a normative procedure (e.g., a calculated score) and signals the reference frames based on their ranks. The bitstream syntax is simplified by using a context tree that relies on the ranking. Moreover, mapping reference frames to buffers does not have to be signaled and can be determined at the decoder. In an example, the identifier of a reference frame used to code a current block can include identifying a syntax element corresponding to the identifier, determining context information for the syntax element, determining a node of a context tree that includes the syntax element, and coding the syntax element according to a probability model using the context information associated with the node. The context tree is a binary tree that includes, as nodes, the available reference frames arranged in the ranking.

Abstract: A computerized method for associating cyberthreat actor groups responsible for different cyberthreats is described. The method involves generating a similarity matrix based on content from received clusters of cybersecurity information. Each received cluster of cybersecurity information is assumed to be associated with a cyberthreat. The similarity matrix is composed via an optimized equation combining separate similarity metrics, where each similarity metric of the plurality of similarity metrics represents a level of correlation between at least two clusters of cybersecurity information, with respect to a particular aspect of operations described in the clusters. The method further involves that, in response to queries directed to the similarity matrix, generating a listing of a subset of the clusters of cybersecurity information having a greater likelihood of being associated with cyberthreats caused by the same cyberthreat actor group.

The systems and techniques use supporting circuitry, such as wiring connectors, in a transmission device that uses diversity antennas to present a conductor connected to electrical ground to receive a portion of a transmission signal generated by at least one of the antennas to couple the signal to ground. In this manner, the isolation element helps to prevent signals from the diversity antennas from merging and thereby supports the diversity antennas' capability of successfully transmitting a signal when an obstacle may impede the signal transmitted by one of the antennas.

Abstract: An impedance-tuned microphone tunnel for an electronic device is disclosed. The impedance-tuned microphone tunnel includes a ring-like structure having a central opening positioned within a microphone tunnel of an electronic device. The central opening of the ring-like structure has a diameter that is smaller than diameters of other central openings within the microphone tunnel. The ring-like structure may be used to tune an impedance of the microphone tunnel by varying the diameter of the central opening. In this way, the impedance of the microphone tunnel may be tuned to a frequency response target to reduce a resonant peak of the microphone tunnel. The ring-like structure may be coated with a non-stick material, such as with polyethylene terephthalate (PET), biaxially orientated polyethylene terephthalate (BoPET), polyimide (PI), and the like.
