  • Patent number: 12206722
    Abstract: Some implementations described herein provide apparatuses and techniques for correcting a network disruption during a virtual meeting. In response to detecting audio and/or video input to a first device, audio and/or video data is recorded and stored in a temporary buffer of the first device. After the network disruption, and using time stamps, a network disruption server may request the audio and/or video data from the first device and transmit the audio and/or video data to a second device at an accelerated rate.

  • Publication number: 20240404944
    Abstract: A semiconductor IC device includes a conductive through device connection. The connection may be located within a double diffusion break (DDB) region that separates active regions. The connection may include a faux S/D region between a frontside contact and a backside contact. The semiconductor IC device may further include a first and/or second diffusion break isolation rail. The connection may be between the first and second diffusion break isolation rails. The connection location within the DDB region may resultantly increase packing densities of the semiconductor IC device. Further, the connection may reduce routing complexities and resistance through the semiconductor IC device, which may improve semiconductor IC device performance. Further, the connection may utilize mirrored structure instances (e.g., frontside contact, backside contact, faux S/D region, or the like) as that are used by microdevices (e.g., transistors, or the like) within the active regions, which may decrease fabrication complexities.

  • Patent number: 11956296
    Abstract: Stream alterations under limited bandwidth conditions is provided. A router on a local network continuously monitors incoming network traffic from a source external to the local network to detect that a bandwidth of the incoming network traffic exceeds a first threshold. The router sends a request to a source of the incoming network traffic to temporarily redirect the incoming network traffic to an optimization analyzer. Analysis is performed on the incoming streams to identify one or more streams for alteration. In response to identifying one or more of the incoming streams for alteration, for each identified incoming stream, continuously altering the identified incoming stream, and re-directing the altered stream to the local device.
