Abstract: A battery cell includes a shell, an end cover, an electrode assembly, and a current collector component. The shell has an opening, and the inner surface of the shell is provided with a first limit part in a protruding manner. The end cover covers the opening. The electrode assembly and the end cover are respectively located on both sides of the first limit part, and the electrode assembly has a tab on the side facing the end cover. The current collector component includes a body part and a connecting part, and the connecting part is connected to the first limit part. The body part includes a first welding region and a second welding region, the first welding region is located on the periphery of the second welding region, the first welding region and the second welding region are separated by the connection position between the connecting part and the body part.

Abstract: Systems and methods for speech recognition are provided. Some methods can include detecting a relative location of a user within one of a plurality of voice pickup areas of a multi-directional microphone array and the multi-directional microphone array activating a setting of the multi-directional microphone array based on the relative location of the user within the one of the plurality of voice pickup areas.

Abstract: An electronic heat transfer label includes a substrate. A pattern layer is printed on the substrate, and an adhesive is printed on the pattern layer to form a first adhesive layer. A chip is attached onto the first adhesive layer, and an adhesive is printed on the chip to form a second adhesive layer. The second adhesive layer covers the chip, and a hot-melt layer is arranged on the second adhesive layer. A method for preparing the electronic heat transfer label includes: S1: printing an ink on a substrate and drying the ink to form a pattern layer; S2: printing an adhesive on the pattern layer and drying to form a first adhesive layer; S3: attaching a chip onto the first adhesive layer; S4: printing an adhesive onto the first adhesive layer and the chip, and drying to form a second adhesive layer.
