  • Publication number: 20240183579
    Abstract: A gas-fired steam boiler, including multiple heat exchange tubes, an upper steam header, a lower steam header, a casing, a burner, a condenser, a chimney, and a controller. The heat exchange tubes are vertically arranged to form an annular tube row. A space enclosed by the annular tube row is configured as a furnace. Adjacent two heat exchange tubes are combined to form a gap channel evenly distributed along a circumferential direction. A width of the gap channel is 0.1-4 mm, and a circumferential length of the gap channel is 50-300 mm. A length of the gap channel along an axial direction of the heat exchange tube is the same as a length of the heat exchange tube.

    Abstract: Techniques for generating content associated with a user input/system generated response are described. Natural language data associated with a user input may be generated. For each portion of the natural language data, ambiguous references to entities in the portion may be replaced with the corresponding entity. Entities included in the portion may be extracted, and image data representing the entity may be determined. Background image data associated with the entities and the portion may be determined, and attributes which modify the entities in the natural language sentence may be extracted. Spatial relationships between two or more of the entities may further be extracted. Image data representing the natural language data may be generated based on the background image data, the entities, the attributes, and the spatial relationships. Video data may be generated based on the image data, where the video data includes animations of the entities moving.

  • Publication number: 20230370074
    Abstract: A method for implementing an atomic clock based on NV-15N coupling spin system in diamond and a device are provided. The method includes: applying a pulse sequence to jointly initialize NV electron spins and 15N nuclear spins; performing a Ramsey interferometry to compare a RF frequency and a 15N hyperfine coupling; entangling the NV electron spin and the nuclear spin, reading out a state of nuclear spins by collecting a fluorescence signal; calculating a frequency difference between the RF frequency and the 15N hyperfine coupling according to the fluorescence signal, thereby locking the RF frequency to the 15N hyperfine coupling; and outputting the RF frequency as a frequency standard. This system is located in a stable solid environment and is not affected by environmental conditions such as an external magnetic field, electric field, and temperature, and therefore it has an excellent robustness.

  • Publication number: 20230298611
    Abstract: In accordance with implementations of the subject matter described herein, a solution for speech enhancement is proposed. In this solution, a target time-frequency representation at least indicating intensities of an input audio signal at different frequencies over time is obtained. The input audio signal comprises a speech component and a noise component. Frequency correlation information and time correlation information of the input audio signal is determined based on the target time-frequency representation. A target feature representation is generated based on the frequency correlation information, the time correlation information, and the target time-frequency representation. The target feature representation is for distinguishing the speech component and the noise component. An output audio signal is generated based on the target feature representation and the target time-frequency representation. The speech component is enhanced relative to the noise component in the output audio signal.

  • Publication number: 20230080210
    Abstract: The subject disclosure provides systems and methods for providing access to media content from a server based on a user interface of a client device through which the access is requested. A user may access certain media content, such as a song, album, playlist, a radio station, etc., only if a request for that content is initiated via a specific user interface, and when the user is a subscriber to a reduced subscription tier to a service of the server. To restrict the access in this way, an interface-specific token is generated at a server for each media content. The interface-specific token is received by a user device and is used for further access to the media content from the server.

  • Patent number: 11522965
    Abstract: In some implementations, a computing system can manage access to media sources associated with a user's media account. For example, the system can coordinate access to a user's media account between local and network devices such that when access to the user's media account is granted to an application on a user device, the application can access both local and network media sources associated with the user's media account. Similarly, when access to the user's media account is revoked from an application at a user device or at a network device, the application is prevented from accessing both local and network media sources associated with the user's media account.

  • Publication number: 20200210459
    Abstract: A candidate sample (T) and respective features (Ft) of the candidate sample (T) are obtained. A predetermined positive integer (N) samples are selected from a classification sample library. A feature similarity (SIMi) is determined between the candidate sample (T) and each of the N samples (i), where the feature similarity (SIMi) is determined based on the respective features (Ft) of the candidate sample (T) and respective features (Fi) of each sample (i). A sample quality (Qi) of each sample (i) is obtained. As comprehensive similarity measures (Si), a comprehensive similarity measure (Si) is determined between the candidate sample (T) and each sample (i) at least based on a difference (ri) between the feature similarity (SIMi) and the sample quality (Qi). Based on the comprehensive similarity measures (Si), a determination is performed as to whether the candidate sample (T) belongs to a classification within the classification sample library.
