  • Publication number: 20220353101
    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. A graphical user interface is presented that enables a user to edit highlighting to select portions of a conference recording for inclusion in the conference summary. The user can edit highlighting on strings of a transcript and/or on a playback slide bar and the highlighting edits are propagated to both of these interfaces. Video clips selected for inclusion in a summary based on timestamps of strings in a transcript may be extended forward in time to incorporate a nearest I-frame of video. The short video or audio summary may be presented to users along with a text summary of the conference to enable efficient storage and transmission of information from the conference within a unified communications system.

  • Publication number: 20220316413
    Abstract: A method of controlling fuel injection to an internal combustion engine to reduce cylinder wall wetting, smokiness, and unclean combustion, on a cumulative basis, applies a self-adaptive control on a gasoline injection initial angle. Gasoline injection initial or original angle is known, being preset, and a self-adaptive controlling volume is added. The self-adaptive controlling volume is the addition of a first self-adaptive controlling volume and a second self-adaptive controlling volume to the original angle. The first self-adaptive controlling volume relates to predicted load and an engine coolant temperature. The second self-adaptive controlling volume is based on the rotating speed of the engine. Cylinder wall wetting is reduced or avoided, smoke is reduced, and cleaner combustion is achieved. An engine fuel injection control apparatus applying the method is also provided.

  • Patent number: 11445484
    Abstract: A method, device, and storage medium are disclosed that determine beam information of an antenna port for a frequency domain resource not used for transmitting uplink data and/or uplink control information. In one embodiment, a first device determines, based on first configuration information, that a beam for sending a first uplink reference signal on a first antenna port is also a beam for sending a second uplink reference signal on a second antenna port, and sends the first uplink reference signal on the first antenna port. Beam information of the first antenna port can be determined based on beam information of the second antenna port, and the first uplink reference signal can be sent based on the determined beam information of the first antenna port. This can spare beam configuration performed by a network side for the first frequency domain resource, and reduce overheads for transmitting configuration information.
