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 gas detection and cleaning system for a vehicle is disclosed and includes an external modular base, a gas detection module and a cleaning device. The gas detection module is connected to a first external connection port of the external modular base to detect a gas in the vehicle and output the information datum. The information datum is transmitted through the first external connection port to a driving and controlling module of the external modular base, processed and converted into an actuation information datum for being externally outputted through a second external connection port of the external modular base. The cleaning device is connected with the second external connection port through an external port to receive the actuation information datum outputted from the second external connection port to actuate or close the cleaning device.
