  • Patent number: 8417928
    Abstract: A computer system includes a hard disk drive and a non-volatile semiconductor memory. The hard disk drive stores a first set of data that includes boot up data. The non-volatile semiconductor memory is distinct from semiconductor memory of the hard disk drive and semiconductor memory of a host of the computer system. A turbo boot driver module stores the boot up data in the non-volatile semiconductor memory and transfers the boot up data from the non-volatile semiconductor memory to a file system of the host during a boot up mode of the host.

  • Publication number: 20120311385
    Abstract: A control sever electronically connects a test server via network interfaces. The test server includes multiple storage mediums that store multiple test programs for testing the test server. The control server includes a switching control unit. The switching control unit selects one storage medium from the storage mediums as a startup device of the test server, and sends a control command to run one or more test programs stored in the startup device. In response to receiving a test result from the test server, the switching control unit selects a next storage medium from the storage mediums as a new startup device, and runs one or more test programs stored in the new staring device until all the storage mediums have been selected as startup devices one by one.

  • Publication number: 20120140704
    Abstract: In order to address the problem of RLC layer relaying in the prior art that downlink user data of a user equipment with an access through a relay station may be lost due to a handover, the invention proposes solutions of a method and apparatus for controlling downlink data transmission in a multi-hop relay communication system so that when a next-hop network device of a base station is a relay station, an RLC entity of the base station transmits an indication message to a PDCP entity of the base station, to trigger the PDCP entity of the base station to discard a PDCP SDU corresponding to at least one PDCP PDU, upon reception of a user equipment delivery acknowledgement message from the access relay station to acknowledge delivery of the at least one PDCP PDU to the user equipment. The access relay generates the user equipment delivery acknowledgement message upon reception from the user equipment of positive acknowledgement messages for all the RLC PDUs corresponding to the at least one PDCP PDU.

  • Patent number: 7929309
    Abstract: A clip is adapted for securing a heat sink on a printed circuit board (PCB). The clip includes a linking portion, an operating portion, a handle, and a pressing portion. The linking portion is located at a lateral side of the heat sink. The operating portion pivotally engages with the linking portion and the heat sink. The handle connects the operating portion. The pressing portion connects the linking portion. A fastener mounted on the PCB extends through the heat sink and the pressing portion. The pressing portion is slidable from a first position to a second position. When the pressing portion is in the second position the handle is operable to drive the operating portion to move upwardly and urge the pressing portion to move along the fastener until the pressing portion abuts against a top portion of the fastener and simultaneously presses the heat sink.

  • Patent number: 7215122
    Abstract: The subject invention relates to a method and apparatus for producing stimulated MRI data. In an embodiment, a remote-controlled “smart phantom” can produce simulated data. The simulated data can be acquired from a MRI system. The subject device can generate control signals and send the generated control signals to secondary coils/probes placed in the subject smart phantom. The control signals determine the current flow in the secondary coils/probes, which act as local spin magnetization amplifiers and thus produce regions of variable contrast to noise ratio. The control signals can be generated with various parameters, such as BOLD models, different levels of contrast-to-noise ratio (CNR), signal intensities, and physiological signals. Comparisons can be made with the widely-used simulated data by computers. Validation of the subject smart phantom can be performed with both theoretical analysis and data of human subjects.
