Abstract: The present application provides a method and apparatus for controlling a device based on tapping and a storage medium. The method includes: in response to a tapping action from a user, acquiring sound information triggered by the tapping action; performing recognition processing on the sound information according to a preset recognition model set to determine a recognition result of the sound information, where the recognition model set includes at least one recognition model; and controlling the device according to the recognition result.

Abstract: The present invention provides a novel process of synthesizing a cathode material. A metal selected from Fe, Mn, Co, Ni, Cu, Zn, Al, Ca, Mg, Ti, V, Cr, Mo or any combination thereof is partially oxidized with an agent such as H3PO4. Then, the metal is fully oxidized with an oxidizing agent such as H2O2. Finally, preparation of the cathode material is completed. The process exhibits numerous technical merits such as less water consumption, less electricity usage, improved product purity, and less usage of base raw materials (e.g. NaOH, Na2CO3, NH3·H2O), among others.

Abstract: An assembly auxiliary jig facilitates assembly of an electronic device having a casing, a first fitting, a second fitting, and a wire. The assembly auxiliary jig includes: a base having therein a receiving space for positioning and receiving the casing and an accessing recess configured to communicate with the receiving space and facilitate access to the casing; a first platform disposed at the base and having a positioning groove in communication with the receiving space to thereby receive the first fitting; a first lid hinged to the first platform and configured to close the positioning groove; a second platform disposed at the base and defined with a positioning recess in communication with the receiving space to receive the second fitting; and a second lid hinged to the second platform and configured to close the positioning recess.
