Abstract: This disclosure is directed to solutions of detecting and classifying wafer defects using machine learning techniques. The solutions take only one coarse resolution digital microscope image of a target wafer, and use machine learning techniques to process the coarse SEM image to review and classify a defect on the target wafer. Because only one coarse SEM image of the wafer is needed, the defect review and classification throughput and efficiency are improved. Further, the techniques are not distractive and may be integrated with other defect detecting and classification techniques.

Abstract: An image sensing device and a control device of an illumination device thereof are provided. The control device includes a control circuit, an operation circuit, and multiple driving signal generators. The control circuit generates multiple control signals. The operation circuit performs a logical operation on the control signals and an image capturing signal to generate multiple operation results. The driving signal generator respectively provides multiple driving signals to the illumination device according to the operation results, and the driving signals respectively have multiple different output powers.

Abstract: A disassembler for an iron sleeve of a drag arm is disclosed. It comprises a top push casing, a bolt nut, a first screw inserted into an iron sleeve of a drag arm and screwed on the top push casing and the bolt nut, a casing for accommodating a bushing, a clamping seat, two positioning elements disposed on the clamping seat for clamping the casing and the bushing and for positioning the casing on the bushing, and a second screw screwed on the casing and contacting the top push casing in the bushing.

Abstract: A pin puller is revealed. The pin puller includes a cylinder mounted with an actuating rod therein. A front end of the actuating rod is connected to and fixed on a pin connection unit. The pin connection unit is fitted over and connected to one end part of a positioning pin while a binding sleeve is disposed around the pin connection unit. The other end part of the positioning pin is mounted and connected to a fixing unit for pin-disassembling or a fixing unit for pin-assembling for driving the cylinder to move the actuating rod. The positioning pin is further pulled to be disassembled or assembled by the pin connection unit. Thereby the pin puller has simpler structure. Thus the manufacturing cost is lowered and the pin puller is having simpler structure and more convenient in operation and use.

Abstract: A surveillance device including a processing module, a lighting module, a movable module, a first camera module and a second camera module. The lighting module is coupled to the processing module to emit light and illuminate a surrounding environment. The movable module is coupled to the processing module. The first camera module is coupled to the processing module. The second camera module is coupled to the processing module, and is disposed on the movable module. When the processing module determines that the amount of light received by the first camera module is lower than a predetermined value, the processing module controls the lighting module to emit light. The processing module uses the movable module to control the second camera module to face towards a direction to the surrounding environment so that the second camera module acquires an image of the surrounding environment.
