Abstract: An improved method and system for image alignment of an inspection image are disclosed. An improved method comprises acquiring an inspection image, acquiring a reference image corresponding to the inspection image, acquiring a target alignment between the inspection image and the reference image based on characteristics of the inspection image and the reference image, estimating an alignment parameter based on the target alignment, and applying the alignment parameter to a subsequent inspection image.

Abstract: A heat dissipation device includes a first radiator, a second radiator, and a first connecting device. The first radiator and second radiator are fastened onto a printed circuit board (PCB) by the first connecting device. The first radiator is over a first electronic device, and the second radiator is over a second electronic device. The first connecting device includes a first fixing pipe, a first fixing post and a first elastic element. The first radiator is fixed with the first fixing pipe, the first fixing post is sleeved in the first fixing pipe, an upper surface of the first fixing pipe abuts against a lower surface of a first convex portion of the first fixing post, a lower surface of the first fixing pipe abuts against an upper surface of the PCB, and the first fixing post extends through the second radiator and the first radiator from top to bottom.

Abstract: A method and system for automatic zoom adjustment is disclosed. Content is displayed on a display screen for a user. In an auto-zoom mode, a first and a second pictures are acquired. Pre-determined features are detected from the first and second pictures. A first and a second feature distances are computed based on the pre-determined features detected from the first and second pictures, respectively. The first and second feature distances relate to the user's head movement relative to the display screen. An adjustment to the zoom of the content on display is determined based on the difference between the first and the second feature distances.
