  • Publication number: 20240114441
    Abstract: A wireless device sends, to a network, a message indicating an enhanced steering of roaming (SOR) capability for network access information for one or more non-public networks (NPN). The wireless device receives, from the network, network access information comprising an identifier of a first NPN and a condition for whether the wireless device is allowed to access the first NPN. The wireless device sends, to the first NPN and based on the condition being met, a registration request message.

  • Publication number: 20240107406
    Abstract: A base station may communicate with one or more other base stations. A first base station may hand over one or more wireless devices served by its cell to a second base station (e.g., a neighboring base station), for example, to save overall energy consumption in the network. Feedback information (e.g., one or more messages) associated with performance of the second base station after the handover may be provided by the second base station to the first base station help further decision-making related to handing over other wireless device(s).

  • Publication number: 20200038595
    Abstract: The present invention provides medical syringe for preventing needle-stick injury, wherein an inner diameter of a middle part of an elastic disengaging ring is larger than an inner diameter of a front part and an inner diameter of a rear part. The elastic disengaging ring is located between a distal wall of a syringe barrel and a needle. When the middle part of the elastic disengaging ring plugged onto the conical fitting of the syringe barrel is radially pinched flat, the proximal end of the elastically deformed elastic disengaging ring leans against the distal wall of the syringe barrel, and the front end of the elastically deformed elastic disengaging ring leans against the proximal end of the needle and pushes the needle to move forward, so that the needle is disengaged from the conical fitting of the syringe barrel.

  • Patent number: 9216020
    Abstract: An endoscopic surgical cutting stapler with a chain articulation is provided, in which a joint is implemented by a chain articulation, teeth are provided at two ends of a chain plate of the chain articulation, and teeth of adjacent chain plates in the same row are engaged. Through mesh transmission of engaged teeth of the adjacent chain plates in the same row, an angle of a most proximal chain plate of the chain articulation is gradually multiplied at several stages and transmitted to an end effector. The end effector can rotate for 90° with small drive motion of the operating mechanism, thereby achieving precise placement of the chain articulation after rotation. The end effector can be precisely aligned with a part to be cut and stapled, and a radius of curvature of the chain articulation can be significantly increased.
