Abstract: The present invention relates to a polyester sound absorption material having improved moldability and decreased weight and a method of manufacturing a molded product using the same, and more particularly to a polyester sound absorption material, which is capable of integrally molding a skin member and a sound absorption material using a felt including a polyester base fiber, a low-melting-point polyester adhesive fiber and a polyester hollow fiber, without the need to attach an additional sound absorption pad onto a skin member.

Abstract: Memory systems and components thereof perform clustering on workload items. Such a memory system comprises a memory device from which data is read and to which data is written; and a memory controller that receives from a host workload items in a workload sequence, each workload item being defined by at least a start logical block address (LBA) and a length. The memory controller merges sequential workload items in the workload sequence to constitute a single workload item; identifies a start workload item for a candidate cluster; stores the LBA and a hit count of the start workload item in a hash table of the memory controller; identifies an end workload item for the candidate cluster; determines whether the candidate cluster is found in the workload sequence more than a threshold number of times; and, if so, accepts the candidate cluster.

Abstract: A controller comprising: a scheduling unit suitable for scheduling a garbage collection recovery operation to be performed in a runtime state after end of abnormal situation using first and second operation logs; a scanning unit suitable for scanning a destination block to detect one or more valid pages during the garbage collection recovery operation; and a map updating unit suitable for updating L2P mapping information of the detected valid pages, wherein the first operation log indicates a location of a valid page, into which source block data is most recently copied, in a destination block, and wherein the second operation log indicates a location of a valid page, L2P mapping information of which is most recently updated, in the destination block.

Abstract: Disclosed is an adaptive polling method of a router including establishing initial values required for carrying out a polling on ports respectively, polling the respective ports in accordance with the established initial values for an established polling interval time, and re-establishing values required for polling to be carried out properly by considering traffic states of the respective ports. The present invention establishes higher polling on ports having larger traffic volumes and lower polling on ports having smaller traffic volumes, so as to improve the performance of a router.
