Abstract: The present application describes one or more map data transmission methods, cleaning devices and storage media. A method may comprise obtaining a first map data corresponding to a current cleaning position and a second map data corresponding to a previous cleaning position. Both the first and second map data may be divided into at least two map layers. The method may further comprise extracting a first map layer data from the first map data and extracting a second map layer data from the second map data. The method may further comprise obtaining the changed first map layer data with respect to the second map data of the same map layer; and sending the changed first map layer data to a computing device (e.g., a cloud server).

Abstract: The present invention provides a method for constructing a high-throughput sequencing library, which comprises: fragmenting genomic DNA; end-repairing the DNA fragments; adding a base A to the 3? end of the end-repaired DNA fragments; connecting the DNA fragments having cohesive end A with a methylated adapter; carrying out hybrid capture on the connection products by using specific probes to obtain object fragments; treating the object fragments with bisulfite, to convert non-methylated cytosines to uracils; PCR amplifying the converted object fragments; and separating and purifying the amplification products, wherein the amplification products constitute the high-throughput sequencing library. The present invention also provides a method and an apparatus for identifying methylation information in specified genome regions of a sample.

Abstract: A DNA library, and a preparing method thereof, a method of determining DNA sequence information, an apparatus and a kit for detecting SNPs, and a method for genotyping may be provided. The method for preparing the DNA library may comprise the steps of: digesting a genomic DNA sample using a restriction endonuclease to obtain a digested product, wherein the restriction endonuclease comprises at least one selected from the group consisting of Mbo II and Tsp 45I; separating the digested product to obtain DNA fragments having a length of 100 bp to 1,000 bp; end-repairing the DNA fragments to obtain an end-repaired DNA fragments; adding a base A to the end of the end-repaired DNA fragments to obtain DNA fragments having a terminal base A; and ligating the DNA fragments having the terminal base A with sequencing adaptors to obtain the DNA library.
