Abstract: A control device for a gearbox which includes a mechanical pump and an electric pump, with the mechanical pump having a first-stage displacement and a second-stage displacement, and the first-stage displacement being less than the second-stage displacement. The control device includes a sensor module for detecting an input speed of a wind wheel, and a rotation speed of the electric pump. The control device also includes a mechanical pump control module for, when the input speed of the wind wheel is greater than or equal to a speed threshold, controlling the mechanical pump to operate at the first-stage displacement, and when the input speed of the wind wheel is less than the speed threshold and the rotation speed of the electric pump is less than a rotation speed threshold, controlling the mechanical pump to operate at the second-stage displacement.

Abstract: A control device for a gearbox which includes a mechanical pump and an electric pump, the mechanical pump having a first-stage displacement and a second-stage displacement, and the first-stage displacement being less than the second-stage displacement, the control device including a sensor module for detecting an oil pressure of a lubricating oil of the gearbox and a mechanical pump control module for, when the oil pressure is above an oil pressure threshold, controlling the mechanical pump to operate at the first-stage displacement, and when the oil pressure is below the oil pressure threshold, controlling the mechanical pump to operate at the second-stage displacement.

Abstract: An air mattress and a production method of an air mattress are provided. The air mattress includes a first sheet and a second sheet, where the first sheet includes a first surface sheet; a periphery of the first surface sheet is provided with multiple first side sheets; the multiple first side sheets are integrally formed with the first surface sheet; adjacent side edges of each two adjacent first side sheets are connected, such that the multiple first side sheets are sequentially connected to form a first enclosing sheet; and the second sheet is connected to an end of the first enclosing sheet away from the first surface sheet.

Abstract: A control device for a gearbox which includes a mechanical pump and an electric pump, the control device including a sensor module configured to detect a system oil pressure of a lubricating oil of the gearbox, a differential, a clutch, a brake, and a control module. The differential includes an input bevel gear meshing with a bevel pinion of an output shaft of the gearbox, a differential housing connected to the input bevel gear, and a first half shaft and a second half shaft which are provided in the differential housing and mesh with a bevel pinion of the differential housing. The second half shaft is connected to an input of the mechanical pump. The brake includes a brake caliper, a brake disc, and a brake disc shaft fixedly connected to the brake disc. The brake disc shaft is fixedly connected to the first half shaft.

Abstract: A planetary carrier, including an input flange, a first web plate connected to the input flange, a second web plate arranged opposite the first web plate, a first support plate connected to a side of the first web plate that faces the second web plate and parallel to the first web plate, and a second support plate connected to a side of the second web plate that faces the first web plate and parallel to the second web plate, the first and second support plates being arranged opposite each other. The side of the first support plate includes a plurality of first support portions. A number of first support portions is the same as that of planetary gear shafts. The side of the second support plate includes second support portions corresponding to the first support portions. Each first support portion and respective second support portion support one planetary gear shaft.

Abstract: A microelectrode sensor for detecting Staphylococcus aureus and a preparation method and an application method thereof are provided. The microelectrode sensor is a three-electrode system sensor with a platinum wire electrode as a counter electrode and an Ag/AgCl electrode as a reference electrode, and a working electrode is a silver microelectrode modified by chitosan, catechol and Staphylococcus aureus aptamers. The microelectrode sensor is constructed based on the microelectrode with micro/nano structure on the surface, dual media (Fc-Ru3+), chitosan, and catechol. The working electrode can specifically capture Staphylococcus aureus. During the CV test of the microelectrode sensor, the Cl? in bacteria will be leaked to a surface of the working electrode under the action of local high-field strength, and when Cl? ions exists, the cathodic reduction peak of the working electrode can be specifically enhanced between 0 to ?0.1 V, the goal of specific detection of bacteria can be achieved.
