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: A vehicle antenna module is adapted to be assembled with a vehicle roof plate and includes a Telematics-Box and an antenna assembly. The Telematics-Box is fixed on the vehicle roof plate and includes at least one first sliding portion, at least one first latching portion and a first connector. The first sliding portion, the first latching portion and the first connector protrude out of at least one assembling hole in the vehicle roof plate. The antenna assembly is slidably arranged on the Telematics-Box, and the vehicle roof plate is located between the antenna assembly and the Telematics-Box. The antenna assembly includes at least one second sliding portion, at least one second latching portion and a second connector. When the second sliding portion slides along the first sliding portion, the second latching portion is latched to the first latching portion, and the second connector is electrically connected to the first connector.

Abstract: A touching rib of an input unit is provided. The input unit comprises the touching rib and a pressing portion including a top face and a bottom face. The present touching rib comprises a main body and at least one auxiliary structure. The main body is disposed on the bottom face for touching an electronic switch in a predetermined distance. The main body has a first predetermined height. The auxiliary structure is formed integrally with the main body and disposed on the bottom face and side by side with the main body. The auxiliary structure has a second predetermined height shorter than the first predetermined height. The auxiliary structure is needed for maintaining the main body having an accurate height, which is corresponding to the first predetermined height, and a smooth surface for touching the electronic surface.
