  • Patent number: 12294507
    Abstract: This application discloses a service level configuration methods and apparatuses, and belongs to the field of communications network technologies. According to an example method, a target service level used by a first forwarding node to forward a data flow is directly determined based on a transmission parameter of the data flow and service level information of the first forwarding node, and service level configuration is performed on the first forwarding node. Because a transmission parameter of the target service level of the first forwarding node and the transmission parameter of the data flow meet a first target condition, if the first target condition is a delay requirement required by a special service and the first forwarding node transmits the data flow by using the target service level, transmission of the data flow may meet the delay requirement required by the special service.

    Abstract: A method of customizing interactive control for a large-format touch-sensitive display device (LFTSDD) is disclosed. One or more images of a scene in front of the LFTSDD are received via a camera of the LFTSDD. The one or more images are computer-analyzed to recognize a human subject in the scene and a location of the human subject relative to the LFTSDD. A variable interaction zone of a display screen of the LFTSDD is determined based at least on the recognized location of the human subject relative to the LFTSDD. The variable interaction zone is smaller than the display screen and positioned a designated distance in front of the human subject on the display screen based at least on the recognized location of the human subject relative to the LFTSDD. A touch control affordance is visually presented in the variable interaction zone of the display screen of the LFTSDD.

  • Publication number: 20250106568
    Abstract: This invention unveils an optical microphone utilizing diamond cantilevers and its associated acoustic sensing system. The core component is a diamond cantilever, featuring a diamond diaphragm with a centrally located U-shaped groove. The manufacturing process involves several key steps: initially preparing the diamond diaphragm using silicon in a chemical vapor deposition setup, where methane and hydrogen are reacted under specific temperature and pressure conditions to form a diamond polycrystalline film on the silicon. This film is then separated from the substrate to create the diaphragm. Subsequently, a U-shaped groove is crafted on the diaphragm by applying a dry etching template and etching, resulting in the formation of the diamond cantilever, with a thickness ranging from 10 to 100 ?m. This method establishes a novel approach to creating sensitive and durable optical microphones.
