Abstract: A method of controlling an electromechanical brake system. The method comprises measuring a voltage of a motor, measuring a current of the motor, and estimating a position of a component of the electromechanical brake system based on the voltage and the current. The method comprises estimating a force imposed by the component based on the voltage and the current, and estimating a hydraulic pressure associated with a hydraulic brake system. In an apply operation, the force of the component is corrected based on the hydraulic pressure. In a release operation, the position of the component is corrected based on the hydraulic pressure.

Abstract: A surgical positioning system and a positioning method thereof arrange positioning elements on a user. An image-capturing device prescans the body of the user to generate a set of scanned images that include first marker points representing the positions of the positioning elements. A host creates a 3D model of the body with the set of scanned images. An X-ray machine scans the body of the user to generate a set of 2D images including second marker points representing the positions of the positioning elements during the operation of the user. The host aligns the second marker points to the first marker points to reconstruct the 3D model, thereby generating a 3D surgical model representing a posture of the user during surgery. The present invention can generate a 3D surgical model corresponding to the user's current posture during surgery to accurately locate the position of the lesion.

Abstract: A bone fixture with various moduli has an implant body. The implant body includes a first implanting segment adapted to be implanted into a cortical bone of a bone and a second implanting segment adapted to be implanted into a cancellous bone of the bone and located below the first implant segment. A first young's modulus of the first implanting segment is smaller than a second young's modulus of the second implanting segment. Because the first young's modulus of the first implanting segment adapted to be implanted in the cortical bone is smaller than the second young's modulus of the second implanting segment adapted to be implanted in the cancellous bone, forces applied to the bone fixture can be evenly distributed to avoid the stress concentration at the cortical bone of the bone.

Abstract: A connectable locking plate assembly comprises a locking plate unit, a connection unit, and a locking component. The locking plate unit comprises multiple interconnecting fixing parts. The connection unit comprises multiple interconnecting positioning parts, and at least one of the positioning parts has an assembly recess. One of the fixing parts is inserted into the assembly recess. The locking component is mounted through the screw connecting hole on the connection unit and is screwed into the screw setting hole of the locking plate unit. Therefore, the connectable locking plate assembly can be assembled into an appropriate structure by assembling the locking plate unit, the connection unit, and the locking component to meet the sizes and outer shapes of the bones at the fracture site. Therefore, the assembly can increase the fitting and fixing effect to the bones, and can enhance convenience during assembling.
