  • Publication number: 20230418856
    Abstract: A pre-training language model-based summarization generation method, including: acquiring text information of a summarization to be generated, and performing multi-feature weighted language pre-training processing on the text information to obtain a candidate summarization; inputting the candidate summarization into a pre-training language model to obtain output data of the pre-training language model; and inputting the output data of the pre-training language model into a decoder model to obtain a target summarization. The pre-training processing is performed on the text information of the summarization to be generated, and then the target summarization can be generated after processing performed by an encoder and a decoder, improving the quality and readability of the summarization.

  • Publication number: 20230280464
    Abstract: Provided are a direct time of flight (dTOF) sensing module, a terminal device, and a ranging method, to resolve a problem that in a conventional technology, a dTOF sensing module cannot adapt to different detection scenarios to some extent. Every K light sensitive units (401) of W light sensitive units (401) included in the dTOF sensing module share a first storage space. A processing control unit (403) is configured to control gating of N light sensitive units (401). The gated N light sensitive units (401) occupy the first storage space, and Q time slice bins are allocated to each gated light sensitive unit (401), so that the dTOF sensing module operates in a first mode or a second mode. The dTOF sensing module is flexibly applicable to different detection scenarios.

  • Patent number: 9136836
    Abstract: In accordance with an embodiment, a converter includes a circuit and method for charging a bootstrap capacitor. The circuit monitors a voltage across the bootstrap capacitor and enables charging the bootstrap capacitor in response to the voltage across the bootstrap capacitor being less than a threshold voltage.

  • Patent number: 7965068
    Abstract: A controller for a multi-phase switching power supply shuffles the sequence of the phases in response to a load transient to prevent synchronization of one or more phases with high-frequency load transients. The sequence may be shuffled by varying the frequency and/or sequence of the switching control signals to introduce a random variation in the phases.
