  • Patent number: 11951271
    Abstract: A high aspect ratio in-plane metal microneedle array, a manufacturing method and a clamping and inserting auxiliary device thereof is disclosed. A large-size metal sheet is cut into small metal sheets. A clamping tooling composed of two upper and lower metal cover plates is processed. Inner sides of the upper and the lower cover plates of the tooling are provided with grooves in which the metal sheets are placed and fastened by bolts. Wire cutting is conducted on the tooling and the metal sheets as a whole to obtain a plane metal microneedle array with a plurality of microneedle bodies. In addition, an assembling and clamping device and an inserting auxiliary device of the high aspect ratio in-plane metal microneedle array is provided. The assembled inserting auxiliary device is placed on skin, and the microneedle array is inserted into the skin through the auxiliary device.

  • Publication number: 20240106039
    Abstract: A battery cell includes a housing, an electrode assembly accommodated in the housing, and an end cover configured to buckle to an opening of the housing. The end cover comprises a first body part, a first end wall, and a first peripheral wall. The first body part is configured to be connected to the housing. The first end wall is farther away from the electrode assembly than the first body part. The first peripheral wall is disposed around an edge of the first end wall and connected to the first body part, and the first peripheral wall and the first end wall jointly form a first accommodation space used to accommodate at least a part of a tab of the electrode assembly. The first peripheral wall comprises a first arc wall extending from the first end wall to the first body part along a first arc trajectory.

  • Publication number: 20190306774
    Abstract: A method includes: establishing, by a terminal, a first communication connection to a first access point by using a first workstation; determining, by the terminal, that signal quality of the first access point meets a handover condition, detecting, by the terminal, a second access point, and establishing, by the terminal, a second communication connection to the second access point by using a second workstation; and determining, by the terminal, that signal quality of the second access point is better than the signal quality of the first access point, and breaking, by the terminal, the first communication connection.
