  • Patent number: 12273807
    Abstract: Techniques for establishing connections between user devices and headless devices attempting to connect to networks. A headless device may attempt to connect to an access point that requires interaction with a captive portal webpage for access to a network. However, the headless device my lack a display to present the captive portal webpage. The headless device may establish a connection with a user device using a PAN protocol. The headless device may then receive the captive portal webpage received from the access point, and relay the webpage to the user device using the PAN protocol. A user may use the user device to interact with the captive portal webpage, and the user device may then relay interaction data back to the headless device using the PAN protocol. The headless device may then provide that interaction data to the access point to be provided access to the network.

  • Patent number: 12270807
    Abstract: A reacting device of dual path synchronous immunochromatographic platform includes a seat, an upper housing, and a fluid dividing funnel. The seat contains two immunochromatographic carriers. The hollow pipe portion has two sloped structures. A force bearing portion of the fluid dividing funnel can be pressed down, so two fluid exits of the fluid dividing funnel move towards these two sloped structures. The specimen drops and is guided into these two immunochromatographic carriers respectively. A reaction result can be observable. The fluid dividing funnel can divide the specimen into two immunochromatographic carriers evenly. The sloped structure can increase the accuracy of specimen supply. Excess specimen can be scraped off for enhancing the solving accuracy. In addition, it can decrease the possibility of false positive problem.

  • Patent number: 12274023
    Abstract: Methods and systems for thermal management of hardware resources are disclosed. To improve the likelihood of the computer implemented services being provided, the systems may include information transmission topologies that are more likely to properly transmit operating point information (e.g., actual fan rates, rates at which fans are to operate, etc.) between management entities such as thermal managers and entities managed by the thermal managers such as fans (and/or other types of gas flow control components). By doing so, the system may be more likely to provide thermal management services as intended by using the transmitted information that is more likely to be accurate.

  • Patent number: 12271598
    Abstract: Techniques for transferring data involve: determining a first physical block in a first storage device, the first physical block having a plurality of data blocks stored thereon. The techniques further involve: determining, based on a first data block of the plurality of data blocks, whether a set of logically contiguous data blocks that comprise the first data block exist in the first physical block, the set of data blocks having a target heat greater than a threshold heat. The techniques further involve: transferring, in response to the existence of the set of data blocks in the first physical block, the set of data blocks into a second storage device for contiguous storage in a second physical block of the second storage device. Accordingly, relatively high heat data blocks are transferred to device with higher access speed, thereby reducing data access time, increasing data processing efficiency, and improving user experience.

  • Patent number: 12267531
    Abstract: A video coding mechanism is disclosed. The mechanism includes receiving at a decoder, a bitstream including a video coding layer (VCL) network abstraction layer (NAL) unit containing a slice of image data divided into a plurality of tiles. A number of the tiles in the VCL NAL unit are determined. A number of entry point offsets for the tiles is also determined as one less than the number of the tiles in the VCL NAL unit. Each entry point offset indicates a starting location of a corresponding tile in the VCL NAL unit. The number of entry point offsets is not explicitly signaled in the bitstream. The entry point offsets for the tiles are obtained based on the number of entry point offsets. The tiles are decoded at the entry point offsets to generate a reconstructed image.
