Abstract: A latch locking type connector has one elastic cantilever and an actuation plate respectively disposed with an inclined plate and a slide corresponding to each other. The upward movement of the inclined plate resulting from the sliding contact of the slide and the inclined plate raises a free end of the elastic cantilever to separate a connector casing from a lead frame. The elastic cantilever pushes and contacts in an opposite direction to return the actuation plate to its original place while allowing a free end of the elastic cantilever to return to its normal position to produce an expected latch locking function when the connector casing and the lead frame are connected to each other once again.

Abstract: An image stabilization method for a camera is provided. The image stabilization method controls the shutter of the camera. The image stabilization method, according to the present invention, first detects whether a trigger signal has been inputted, wherein the trigger signal is inputted by a user and starts an image capturing process. Next, the time when the trigger signal was inputted is detected and recorded as a first time. Afterwards, a stabilization time is delayed based upon the first time. Finally, a drive signal is generated when the stabilization time ends, wherein the drive signal drives the shutter to turn on for executing the image capturing process.

Abstract: An aberration compensation system for digital camera and a method therefor are provided, wherein the system includes an optical lens, an axial moving mechanism, a photosensitive element, and an image unit. The photosensitive element is loaded on the axial moving mechanism, and generates a first and a second image at a first and a second focus position. After receiving the first and second images, the image unit respectively calculates a first and a second image capture region and then synthesizes the two regions into a third image. The method includes using the optical lens to project the light beams of an object to be shot, generating the first image and second images, and capturing the distinct portions of the first and second images to be synthesized into the third image. Thereby, the system and method can solve the non-uniformity of the definitions at the center and periphery of each image.

Thereby, the device with a lens-rotation mechanism proposed by the present invention can control the rotation of a lens.

Abstract: A method for smoothing a printed circuit board (PCB), comprising: providing a PCB having a first smooth outer surface and an opposite second outer surface, the second outer surface including a smooth region and a plurality of dimples; applying a liquid photoresist layer onto the second outer surface of the PCB to fill the dimples; solidifying the liquid photoresist in the dimples to obtain a solidified photoresist layer; polishing the solidified photoresist layer until a surface thereof being coplanar with the smooth region; and polishing the entire second outer surface until the solidified photoresist layer is removed, thereby obtaining a plain outer surface parallel to the first smooth outer surface.

Abstract: A knob structure includes a holder, a steel ball, an elastic metallic piece, a swiveling element and a connecting element. The holder has at least one through hole. The steel ball is slidably placed inside the through hole. The elastic metallic piece and the swiveling element reside at either sides of the holder. The elastic metallic piece slidably lies against the steel ball. The swiveling element has a sliding portion which has a plurality of notches spaced at intervals. The sliding portion slidably lies against the steel ball so that the steel ball slides into or out of the notches by turning the swiveling element. The steel ball has a smooth surface and is in point-to-point contact with the sliding portion and with the elastic metallic piece. Therefore, frictions therebetween are so small that no scraps generate due to the frictional operation.
