A dispatch system for autonomous vehicle is provided. The dispatch system includes a plurality of autonomous vehicles respectively including a communication unit and a control unit. The communication unit obtains a vehicle location information of itself, and communicates with other autonomous vehicles. The control unit obtains a vehicle available information of itself. One of the autonomous vehicles is selected as a dispatch control center for controlling scheduling of all autonomous vehicles. When the dispatch control center receives a transportation request massage, the dispatch control center performs an optimized scheduling assignment and thus generates a scheduling signal. The scheduling signal is transmitted to the other autonomous vehicles by the communication unit, so as to assign one of the autonomous vehicles as a designated vehicle for transportation.

A method for generating a data-bearing image is implemented by an encoding system including a halftoning module and an encoding module that stores encoding rules associated with respective codes. In the method, the halftoning module converts a grayscale image into a halftone image having a plurality of image cells each consisting of a plurality of dots, at least one of which is a first-tone dot and each of the rest of which is a second-tone dot. Afterward, the encoding module generates a data-bearing halftone image encoded with at least one of the codes by maintaining or changing the number of the first-tone dots in one of the image cells based on one of the encoding rules associated with the at least one of the codes.

A side grating based light coupling system comprises an optical fiber, a side grating disposed on one side of the lateral wall of the optical fiber, and a laser array disposed adjacent to the other side of the lateral wall of the optical fiber. The side grating comprises a plurality of grating elements arranged in a non-uniform arrangement. The laser array for generating a laser beam towards and passes through the optical fiber, and the laser beam is converted into at least one laser beam through the plurality grating elements. The diffraction efficiencies of the converted laser beams are different. The converted laser beams propagate inside the optical fiber based on total internal reflection. The plurality of grating elements of the side grating are heterogeneous arrangement without loading the optical collimating lens, and can reduce scattering loss by controlling the asymmetric diffraction efficiency, to improve optical coupling efficiency.

A vertical-transition structure comprises a microstrip line and a combination of a coaxial connector and a metallic ring underneath the microstrip line. A first through hole is created next to the microstrip line and near one end of its signal line. The metallic ring has a second through hole. The coaxial connector has a center conductor including an extended portion to be inserted into the second through hole via its center, and subsequently through the first through hole to connect to the signal line vertically. Specially, the extended portion is not inserted through the center of the first through hole. The present structure can improve the high-frequency insertion loss of the vertical transition caused by the sudden change of electromagnetic field distributions from a coaxial line to a microstrip line and the resonant is response of the coaxial connector, and therefore, increase the 1-dB transmission passband of the vertical transition substantially.
