Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: An original type damping-adjustable shock absorber is revealed. An adjustment rod is mounted into a through hole of a piston body while a knob is disposed on a top end of a main body of the adjustment rod and a tapered-end rod is connected to a bottom end of the main body. A tapered-head of the tapered-end rod is inserted into a channel under the through hole. An insertion hole is located at a wall of the piston body and communicated with the channel. The depth of the tapered-head of the tapered-end rod inserted into the channel can be adjusted so as to change resistance of hydraulic oil flowing through the channel and damping level of the shock absorber. Thus an original car runs smoothly over roads with various surfaces. Therefore features of the original car including a comfort rid and a sense of value are highlighted.
