  • Publication number: 20200410221
    Abstract: Embodiments of this disclosure provide an arm action identification method and apparatus and an image processing device. A human body detection is performed on an image to obtain multiple key points of the human body in the image. An arm action is identified to be an upward action or a downward action by using a shoulder key point, an elbow key point and a wrist key point in the multiple key points. Arm actions indicative of upward, downward, or forward, actions may be identified based upon, for example, lifting, putting down, holding forward, actions, by using the key points of the human body, thereby achieving computer-level action identification, and lowering complexity of computation.

  • Publication number: 20200323353
    Abstract: The present invention concerns a spring core (1, la, 12, 13, 17, 18) that may be used in e.g. bed mattresses, chairs or sofas. The spring core (1, 1a, 12, 13, 17, 18) comprises springs placed inside pocket (3). The pockets (3) are placed in a number of rows, which rows of pockets (3) are placed side by side. The spring core (1, 1a, 12, 13, 17, 18) is held in a compressed state by means of at least one cord (5). The at least one cord (5) is formed into braids (6) at opposite outer ends (7) of each row of pockets (3). Further, the at least one cord (4) forms a number of loops (8) on at least one side of each row of pockets (3). By pulling at one free end (10) of the at least one cord (5) the braids (6) and loops (8) are dissolved, allowing the spring core (1) to return to the non-compressed state.

  • Publication number: 20200198961
    Abstract: Disclosed are a bagged spring bed core with a side connected to a strip-shaped material and a manufacturing device and method thereof. The bed core is formed by arranging and bonding bagged spring strings connected to a strip-shaped material. The device includes a string feeding mechanism, a feeding mechanism, a tidying mechanism, and a sealing and cutting mechanism. The sealing and cutting mechanism cuts off the bagged spring string and the strip-shaped material to form bagged springs connected to the strip-shaped material. By bonding the strip-shaped material, the bagged spring string is no longer easily elongated or shortened by the action of an external force, so that the finally formed bagged spring bed core has good dimensional stability and can be compressed and coiled for packaging. Moreover, the strip-shaped material is provided between adjacent bagged spring strings in the bed core, so that the bed core has better durability.
