  • Publication number: 20100070060
    Abstract: A method for designing a light guide plate includes the following steps. A raw light guide plate having a light input surface and a light output surface is provided. A region of the light input surface is divided into several annuluses according to a luminance distribution E(?,?) of the light output surface. A scattering dots density D(?,?) of each annulus on the light input surface is figured out. A total number N of the scattering dots of each annulus on the light input surface are gained, and the scattering dots is randomly distributed in the each annulus defined on the light input surface, whereby a designed light guide plate is obtained.

  • Publication number: 20090252147
    Abstract: A storage server implemented by an internet small computer systems interface (iSCSI) in a Linux system includes a network subsystem and a small computer systems interface (SCSI) subsystem, and an iSCSI module and a SCSI module are respectively embedded in the network subsystem and SCSI subsystem. When receiving a link request packet from an initiator, the network subsystem creates a SCSI identifiable format packet for the SCSI subsystem by the embedded iSCSI module and the embedded SCSI module. The iSCSI module and SCSI module are respectively embedded in the network subsystem and SCSI subsystem. The iSCSI module and SCSI module can be immediately called without waiting the switch of processing, thereby solving performance bottleneck in the storage server and improving the operation speed of the storage server.

  • Publication number: 20090127949
    Abstract: A permanent-magnet synchronous gearless traction machine. The traction machine includes a permanent-magnet synchronous motor having a spindle; a traction wheel coupled to the spindle of the permanent-magnet synchronous motor; a first brake; and a second brake, wherein at least one of the first brake or the second brake is coupled to the traction wheel. As such, in the traction machine, since at least one of the first or second brakes is coupled to the traction wheel, the braking torque generated by the brake coupled to the traction wheel can brake the traction wheel directly, and thereby the operation safety of the elevator can be improved effectively.
