  • Publication number: 20220113833
    Abstract: Disclosed are a processing method and system for touch signals, and an all-in-one touch machine. The method includes: obtaining current infrared signal data on a surface of an infrared touch bezel; obtaining touch-obstructed areas according to the current infrared signal data; determining whether the number of the touch-obstructed areas is greater than a predetermined value, uploading the current infrared signal data to the control mainboard if the number is greater than the predetermined value, or performing simple touch-control calculations on the current infrared signal data through the infrared touch bezel if the number is less than or equal to the predetermined value and obtaining coordinate information of a touch point; performing complex touch-control calculations by the control mainboard according to the current infrared signal data received, and obtaining the coordinate information of the touch point and returning the coordinate information to the infrared touch bezel.

  • Publication number: 20210161131
    Abstract: The present invention discloses the preparation method of cis-p-menthane-1,8-di-secondary amine compounds and their application in weed control. The preparation method is as follows: cis-p-menthane-1,8-di-Schiff base compounds are used as the raw material, and the reducing agent is added in batches into the raw material in a polar organic solvent at ?10˜50° C. to react for 1˜24 h; after the reaction is complete, the reaction solution is quenched with distilled water and extracted with dichloromethane, and the extract phase is dried with anhydrous sodium sulfate, filtered with a filter and then distilled under reduced pressure to obtain crude cis-p-menthane-1,8-di-secondary amine compounds, which are purified into the pure product through recrystallization or silica gel column chromatography.

  • Patent number: 10674723
    Abstract: This invention discloses a type of 1,8-bis(Schiff base)-p-menthane derivatives as well as their preparation method and applications. The reaction of 1,8-diamino-p-menthane with a substituted benzaldehyde was carried out in a polar organic solvent at 0° C.-75° C. for 1-48 h. After the completion of the reaction, part of the solvent was distilled off to perform recrystallization to get a 1,8-bis(Schiff base)-p-menthane derivative, whose pre-emergence herbicidal activity against ryegrass was determined by using the Petri dish seed germination method. The 1,8-bis(Schiff base)-p-menthane derivatives, obtained with this method in high yield and mild reaction conditions, have a good inhibitory effect on the growth of annual ryegrass, and low toxicity.

  • Publication number: 20200111599
    Abstract: An inductor is disclosed. The inductor includes a magnetic core and a coil. The coil includes a first part coil and a second part coil. The first part coil is conductive paths disposed on a circuit board. The second part coil is a group of conductors plug-connected to the circuit board. The conductive paths of the circuit board and the conductors plug-connected to the circuit board are interconnected. For the inductor, the conductors are plug-connected to the circuit board, to form a continuous conductive winding wound around the magnetic core. In the inductor, different types of conductive media are combined to form the coil of the inductor, so that a repeated wire winding action required of a single coil does not need to be performed in a manufacturing process, and the magnetic core does not need to be cut and bonded in the manufacturing process.
