Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A method for manufacturing a memory device is provided. The method includes etching an opening in a first dielectric layer; forming a bottom electrode, a resistance switching element, and a top electrode in the opening in the first dielectric layer; forming a second dielectric layer over the bottom electrode, the resistance switching element, and the top electrode; and forming an electrode via connected to a top surface of the top electrode in the second dielectric layer.

Abstract: An image object classification method and system are disclosed. The method is executed by a processor coupled to a memory. The method includes: providing an image file including at least one image object, performing a process of extracting multiple binary-classified characteristics on the image object to obtain a plurality of first results independent of each other in categories, combining the plurality of first results in a manner of dimensionality reduction based on concatenation, performing a process of characteristics abstraction on the combined first results to obtain a second result, and performing a process of characteristics integration on the plurality of first results and the second result in a manner of dot product of matrices to obtain a classification result.

Abstract: A flexible interface (130) may operably couple a head portion (110, 210) and a shaft (120, 220) of a hand tool (100, 200). The flexible interface may include a retention assembly (160) and a locking assembly (150) including an actuator (152, 250, 250?) defining a locked state and an unlocked state for the hand tool. In the unlocked state, an angle of the head portion may be pivotable relative to a pivot axis (225) substantially perpendicular to a direction of extension of the shaft and, in the locked state, the angle of the head portion is fixed. The actuator may be configured to move in a direction substantially perpendicular to the pivot axis to operate the locking assembly to transition between the locked state and the unlocked state, and configured to move in a direction substantially parallel to the pivot axis to operate the retention assembly to retain hand tool in the unlocked state. A hand tool comprising said flexible interface is also related.

Abstract: A hand tool (100,200) may include a head portion (110,210) configured to interface with a fastener, a shaft (120,220) and a grip portion at which an operator is enabled to hold the hand tool during operation, and a flexible interface (130,230) configured to operably couple the shaft and the head portion in a locked state and an unlocked state. The flexible interface is also configured to enable the head portion to pivot relative to the shaft about a pivot axis that extends substantially perpendicular to a direction of extension of the shaft. In the unlocked state, an angle of the head portion may be pivotable relative to the pivot axis. In the locked state, the angle of the head portion may be fixed. The flexible interface may include a locking assembly (150) including an actuator (152, 250, 250?) having a locked position defining the locked state and an unlocked position defining the unlocked state.

Abstract: A light guide for a keypad includes a plurality of through hole portions adapted to correspond respectively to keys on the keypad. Each of the through hole portions is adapted to receive at least a part of the corresponding key, and to receive light incident thereinto from at least one light source. Each of selected ones of the through hole portions has a contour with a non-curved contour portion that includes a light incident face and a reflecting face forming an angle with the light incident face. Light incident on the reflecting face is reflected into at least one other through hole portion. The light guide can also be configured to have a tree-like structure.

Abstract: A rotating mechanism comprises a base, a rotating device and a rebound device. The base includes a base body, a base joint and a first shaft. The base joint and the first shaft are disposed on the base body respectively. The rotating device includes a rotating device joint. The rotating device is capable of rotating the first shaft. The rotating device joint is able to circle around the first shaft. Two ends of the rebound device are pivotally connected to the base joint and the rotating device joint respectively. The rebound device is capable of deforming and rotating the base joint and the rotating device joint.

Abstract: A screw mounting jig. The jig supports an electronic device thereon. The electronic device includes a first surface and a second surface opposite to the first surface. A first screw hole is formed on the first surface, and a second screw hole is formed on the second surface. The jig includes a base and a supporting assembly. The electronic device is received in the supporting assembly. The supporting assembly is disposed on the base in a manner such that it rotates between a first position and a second position. When the supporting assembly is located at the first position, the first surface faces the base so that the second screw hole is exposed for insertion. When the supporting assembly is located at the second position, the second surface faces the base so that the first screw hole is exposed for insertion.
