Abstract: The present disclosure discloses a design method for lightweight wired Mesh networking. The design method includes: designing a protocol format of a lightweight wired Mesh network message; designing an input parsing module of the lightweight wired Mesh network message; designing a heartbeat logic module between devices of the lightweight wired Mesh networking; designing a route management module of a lightweight wired Mesh network; designing a forwarding and processing module of the lightweight wired Mesh network message; and designing an underlying hardware interface management module.

Abstract: A battery includes a casing having two first peripheral portions and two second peripheral portions, a cell disposed within the casing, two conductive tabs electrically connected to the cell and exposed from at least one of the first peripheral portions, and an absorbent. Each of the second peripheral portions has a sealed region that has a sealed edge adjacent to the cell. The sealed region of at least one of the second peripheral portions has an inner sealed section disposed adjacent to the sealed edge, an outer sealed section, and an isolating section disposed between the inner sealed section and the outer sealed section. The absorbent is received in the isolating section for absorbing moisture or gas.

Abstract: A tab includes a tab body, where the tab body includes a first end, a second end, and a side connected to the first end and the second end along a length direction. The tab further includes a plurality of protruding portions and/or recessed portions disposed on the side, where the plurality of protruding portions have different maximum heights or the plurality of recessed portions have different maximum depths. During packaging, the tab helps improve packaging reliability.
