Abstract: A system and method for jointly displaying an image and a map is disclosed. The method may including obtaining an image captured by a camera. The image may include a target in a surrounding environment of the camera. The method may further include obtaining a map of the surrounding environment. The map may at least include a location corresponding to the target and a location corresponding to the camera. The method may jointly display the image and the map, wherein a representation of the image is aligned with the location corresponding to the target and the location corresponding to the camera in the map.

Abstract: A hoist for transferred materials in an underground auxiliary transportation system and a method thereof. The hoist includes a hoist body, guiding plates mounted at two ends of the hoist body through bolts, twist locks mounted at four ends of the hoist body, a driving unit configured to drive twist locks to rotate, transmission assemblies configured to connect the twist locks with the driving unit, ejector pins configured to prevent the twist locks from rotating mistakenly, and a sensor configured to control the hoist to operate and provide protection safety.

Abstract: A grooming method and apparatus for a packet optical transport network are disclosed. The method includes: according to an arrangement order of various services, planning a path from a service source node to a service target node in an ith service in a topology set graph; when the path includes a wavelength link in a physical link, removing the wavelength link, and establishing a virtual link between a link source node and a link target node of the removed wavelength link; updating capacities of various links in the path; calculating a weight of a newly established virtual link, and adding the newly established virtual link and the corresponding weight to the topology set graph; and planning a path from a service source node to a service target node in an i+1th service in the topology set graph, until all services are finished.

Abstract: The present invention relates to a back sheet for solar cell and a method of manufacturing the same. The back sheet for solar cell comprises a substrate and a fluoropolymer layer, wherein the components by weight of the fluoropolymer layer are as follows: 25˜45 parts of fluororesin; 1.5˜3 parts of modified resin; 0.5˜3 parts of polymeric filler; 0.1˜1 parts of inorganic filler; and 50˜70 parts of solvent. The back sheet for solar cell provided by the present invention has low cost and excellent performances, such as high peeling strength, good waterproof performance, and good weathering resistance. The method of manufacturing the back sheet for solar cell provided by the present invention is simple in process, and thus can achieve continuous industrial production.
