Abstract: A method includes: obtaining, by a first electronic device, a photographing instruction; determining location information of to-be-photographed content corresponding to the photographing instruction or a photographing mode according to the photographing instruction, and determining, a camera at the most suitable location for photographing the to-be-photographed content from at least two cameras controllable by the first electronic device as a target camera, where the at least two cameras include a camera on the first electronic device and a camera of a second electronic device, and the first electronic device is different from the second electronic device; and controlling, by the first electronic device, the target camera to execute the photographing instruction to obtain image data acquired by the target camera.

Abstract: A refrigerator includes a top cover which separates a storage liner on a bottommost portion into a storage space located on an upper portion and a cooling space located on a lower portion. At least one return air hood is arranged at a front end of the top cover, the cooling space is jointly defined by the return air hood, the top cover and a bottom wall of the storage liner, and an evaporator is arranged in the cooling space. The return air hood includes a return air frame located on a front side and a return air rear cover inserted into the return air frame from an open rear end of the return air frame. The return air rear cover is arranged to separate a first opening formed in a front wall face of the return air frame into a first front return air inlet located on an upper portion and a second front return air inlet located on a lower portion, so that the visual attractiveness is achieved, and the fingers of children or foreign matter can be effectively prevented from entering the cooling space.

Abstract: The present disclosure provides mint-containing composite cellulose fibers and production methods thereof. A mint-extract crude solution is prepared from a whole mint plant after at least one water extraction process and at least one ethanol extraction process to provide a mint-extract filtrate and mint-extract residues. The mint-extract filtrate is used as the mint-extract crude solution. The mint-extract crude solution is treated to prepare a mint-extract stock solution by at least a quenching process. A viscose spinning solution is prepared by mixing the mint-extract residues with one or more pulps selected from a cotton pulp, a wood pulp, a bamboo pulp, a wool pulp, a linen pulp, a silk pulp, a Tencel pulp, and a Modal pulp. The one or more pulps contain cellulose. A mint-viscose blend is prepared by dynamically mixing the mint-extract stock solution with the viscose spinning solution and then spun into the mint-containing composite cellulose fiber.

Abstract: A multilingual apparatus detects the linguistic encoding type of a digital string encoding a domain name. It accomplished this using a tree or graph comprised of nodes holding linguistic digits representing the digital sequence of a character or a portion of a character. These nodes are compared against digital sequences of characters in the domain name under consideration. Each comparison results in a step down the graph. Then another comparison is performed, often with the next successive character in the domain name. Ultimately the process reaches a terminal node of the graph. This terminal node specifies the encoding type of the domain name under consideration.
