  • Patent number: 10409683
    Abstract: A data storage system configured to perform a data rebuild operation via a reduced number of read requests includes a host and a redundant array of independent disks (RAID) device including a plurality of data storage devices. When the host receives data of a first region and data of a second region of a read-requested region of each of the data storage devices in response to a rebuild request, the host receives failed address list information of the second region. The first region is a normal region, and the second region is a faulty region. The host rebuilds the data of the second region based on the failed address list information.

  • Patent number: 10400370
    Abstract: The present invention relates to a nonwoven fabric or nonwoven composite material comprising the nonwoven fabric for shielding and absorbing electromagnetic waves, manufactured by using a carbon fiber plated with metal (copper and nickel) produced in an electroless or electrolysis continuous process. The nonwoven fabric of the present invention is thinner and stronger than the conventional art, and has an advantage of being capable of controlling conductivity by controlling only the content of the carbon fiber plated with metal, without need for further addition of conductive powder.

  • Patent number: 10385208
    Abstract: The present invention relates to a preparation method for an electromagnetic wave shield composite material and the electromagnetic wave shield composite material prepared by the method. The present invention uses a highly conductive carbon fiber prepared by electroless and electrolytic continuous processes, and thus is suitable for an EMI shield due to having an excellent conductivity and low surface resistance, and is capable of providing the electromagnetic wave shield composite material having an excellent productivity and economic value. Furthermore, the electromagnetic wave shield composite material of the present invention can be used for blocking electromagnetic waves by being inserted into a cell phone cover and a cell phone pouch, and can also be applied to a bracket for protecting an LCD of a portable display product.

  • Patent number: 9547228
    Abstract: An image correction method is disclosed. The method includes at least: identifying an overlapped area in an image projected by a plurality of projectors; determining a difference of at least any one of brightness and color of the overlapped area and a non-overlapped area of the image; and adjusting a factor among the brightness and the color in which the difference is generated.

  • Publication number: 20160212467
    Abstract: Disclosed herein is the playback of content in a multi-projection theater equipped with a plurality of projection surfaces. More particularly, the present invention relates to obtaining content information about main content from screening-related apparatuses, obtaining organization information about the main content from an external server, and generating a single time line by mapping the content information to the organization information. The generated time line is used to determine the playback schedule of sub-content to be played back in auxiliary projection surfaces of a plurality of projection surfaces. The present invention relates to an integration playback apparatus and integration playback method for organically integrating and playing back main content and sub-content in a multi-projection screening environment.
