Abstract: Disclosed are an intelligent dimmer and a structure of an on-off assembly thereof. A first key device in the on-off assembly includes a rocker key and a movable ejector rod, one end of which is connected to an ejector rod spring and the other end of which is arranged in a groove. The movable ejector rod cooperates with a moving contact assembly including two moving contacts and two contact surfaces, the contact surfaces are connected to the corresponding moving contacts, and the moving contact assembly is connected to a circuit in a printed circuit board (PCB). The movable ejector rod is arranged between the two contact surfaces, and the rocker key is capable of driving the movable ejector rod to swing and act on the corresponding contact surface, such that the moving contact assembly swings and is connected to or disconnected from a corresponding stationary contact.

Abstract: Disclosed is an intelligent high-power ground fault circuit interrupter (GFCI) plug. The plug includes a leakage detection device, a driving device and a printed circuit board (PCB), where when the leakage detection device detects leakage, the driving device acts to disconnect a circuit. The driving device includes a coil and a driving rod, a current is input the coil, and the driving rod is driven to act, such that a moving contact is in communication with or disconnected from a stationary contact. A permanent magnet assembly is further included. Due to the position of the permanent magnet assembly, when the moving contact is in communication with the stationary contact, the permanent magnet assembly and the driving rod are magnetically attracted and maintained.

Abstract: A jack device includes a frame, a lifting assembly, a hydraulic assembly, a power unit, and a battery pack coupling portion. The lifting assembly is pivotally connected to the frame, one end of the lifting assembly includes a lifting pad liftable or lowerable, and the lifting pad provides an upward lifting force for a lifted object. The hydraulic assembly is configured to drive the lifting assembly to perform a lifting action or a lowering action. The power unit includes an electric motor, a reduction mechanism, and an actuator, where the reduction mechanism is disposed between the electric motor and the actuator, and the actuator is able to drive the hydraulic assembly to operate. The battery pack coupling portion is used for mounting a battery pack, where the battery pack supplies power to at least the power unit.

Abstract: A cutting tool includes a housing, a battery pack coupling portion, an electric motor, a control board, a control unit, and a display assembly. The battery pack coupling portion is configured to be connected to a battery pack for powering the cutting tool. The electric motor can drive a working accessory to rotate and is electrically connected to the control board. The cutting tool further includes a display mechanism. The display mechanism includes the control unit and the display assembly. The control unit is electrically connected to the control board. The display assembly is electrically connected to the control unit. When the control unit transmits an electrical signal to the display assembly, the display assembly displays a rotation direction of the electric motor or other information.

Abstract: A power tool includes an electric motor including a rotor and three-phase stator windings, where the stator windings have a certain electrical conduction angle when the electric motor operates; a driver circuit having multiple semiconductor switching elements; a parameter detection module for detecting a working parameter of the operating electric motor; and a controller electrically connected to at least the driver circuit and the electric motor. The controller is configured to acquire the working parameter; and according to the working parameter, correct the electrical conduction angle of the stator windings of the operating electric motor. A power tool that can accurately detect a commutation point and adjust the conduction angle of the electric motor windings accordingly is provided.

Abstract: The invention relates to a microcarrier, comprising a continuous medium of a biocompatible polymer for culturing cells and having a three-dimensional scaffold architecture delineated peripherally by a continuous outer wall, in which spherical macropores are stacked to one another and interconnected by connecting pores. The continuous outer wall is formed with exposure pores at positions where it is in contact with the macropores, through which the interior of the microcarrier may be in fluid communication with the ambient culture medium. The microcarrier herein is produced by cast-molding and, therefore, has a continuous outer wall which provides additional mechanical strength while maintaining high porosity. The microcarrier thus produced is configured in the form of a basic geometrical body. The invention further relates to a cast-molding process for producing the microcarrier.
