  • Patent number: 9304910
    Abstract: A storage system and method for interleaving a plurality of logical sectors in the storage system is disclosed. The method includes: dividing each logical sector into a predetermined number of slices; sequentially indexing the logical sectors, wherein each logical sector is identified by a logical sector index; sequentially indexing the predetermined number of slices in each logical sector, wherein each slice of the predetermined number of slices is identified by a slice index within each logical sector; and interleaving the logical sectors according to a slice interleaving process. The interleaving step further includes: a) identifying a first indexed slice of a first indexed logical sector as an initial slice; and b) identifying a subsequent slice by advancing the slice index to a subsequent index in the slice index sequence and advancing the logical sector index to a subsequent index in the logical sector index sequence.

  • Patent number: 9185527
    Abstract: A server includes a communication module, a database and a processor. The communication module receives identification information of a user of a mobile terminal and a movement status and a geographic position of the user from the mobile terminal. The processor determines real time traffic condition of the geographic position of the user according to the real time traffic information of the area where the user is located stored in the database and evaluates a time period to be spent from the geographic position of the user to the display terminal according to the movement status of the user and the real time traffic condition of the area. The communication module further transmits the geographic position of the user, the evaluated time period and the identification information of the user to the display terminal. A system including the server and a method of displaying a user status are also disclosed.
