A speckle contrast reducing method for a laser scanning projection system includes the following steps. Firstly, a laser beam is provided. The laser beam is projected on a projection surface according to a first scanning trajectory, thereby generating a first image frame. Sequentially, the laser beam is projected on the projection surface according to a second scanning trajectory, thereby generating a second image frame at an image refresh rate. Moreover, the second scanning trajectory of the second image frame is shifted by a displacement from the first scanning trajectory of the first image frame along a slow-axis direction.

A paper pallet made of paper includes two supporting stringers and a plurality of deck rods. The supporting stringers extend horizontally in a first direction, and are spaced apart from each other in a second direction transverse to the first direction. The deck rods extend horizontally in the second direction, are arranged in the first direction, and are disposed on and connected to top surfaces of the supporting stringers. Each deck rod includes an elongated plate portion elongated in the second direction and having two elongated outer edges opposite to each other in the first direction and two elongated tubular portions. The elongated tubular portions of each deck rod are disposed juxtaposed with each other in the first direction. Each elongated tubular portion of each deck rod extends from a respective one of the elongated outer edges and is bent into a rectangular tubular structure.

A watertight switch comprises a cover and a base assembled together to form an accommodating space for mounting a switching module therein. The cover and the base, at the combination interface therebetween, respectively have a first junction interface and a second junction interface, which are inwardly shrunk to form a binding gap, the binding gap is gummed by an adhesive for fixedly combining and positioning the first and the second junction interfaces, and the adhesive will fill the binding gap without flowing over the first and the second junction interfaces.
