  • Publication number: 20140133283
    Abstract: A TAMR (Thermal Assisted Magnetic Recording) write head uses the near field energy of optical-laser excited plasmon eigenmodes in a plasmon resonator to locally heat a magnetic recording medium and reduce its coercivity and magnetic anisotropy. The plasmon resonator is formed as a conducting disk-shaped structure with an extending peg that serves to further confine the near fields within a small region of the recording medium. The resonator eigenmodes are excited, through direct or evanescent coupling, by an interference pattern formed by the overlap of optical waves within a dual-channel waveguide, the interference pattern being the result of the waves in one branch being phase-shifted relative to the waves in the other branch.

  • Publication number: 20140123473
    Abstract: A method of forming a TAMR (Thermal Assisted Magnetic Recording) write head that uses the energy of optical-laser excited plasmons to locally heat a magnetic recording medium and reduce its coercivity and magnetic anisotropy. The magnetic field of the write head is enhanced by the formation of a leading shield that is formed in a concave geometrical shape and partially surrounds the waveguide portion of the head within the concavity, which allows the distal end of the waveguide to extend to the ABS plane of the write head. This arrangement reduces the gap between the shield and the magnetic pole and does not interfere with the ability of the waveguide to efficiently transfer its optical energy to the plasmon generator and, ultimately, to the surface of the magnetic recording medium.

  • Patent number: 8621534
    Abstract: The present invention discloses a method, system, and device for admission control and pertains to the communications field. The method includes: admitting a subscriber for watching a multicast video only if each multicast bandwidth management device has sufficient remaining bandwidth after receiving a multicast video request from the subscriber; refusing the subscriber for watching the multicast video if any multicast bandwidth management device has insufficient bandwidth and fails to borrow bandwidth from a unicast bandwidth management device; and after receiving a unicast video request from the subscriber, admitting the subscriber for watching a unicast video only if remaining unicast bandwidth corresponding to a multicast bandwidth management device in each level is sufficient, or else, refusing the subscriber for watching the unicast video. Through bandwidth negotiation between the unicast bandwidth management device and each multicast bandwidth management device, admission control is implemented.

  • Patent number: 8429465
    Abstract: A method, device and system for managing resources in networks are provided, which relate to the field of data communication. The method includes the following steps. A resource manager (RM) sends a first request message according to a received resource request message, to request an access node (AN) to perform admission control. After receiving an admission control result indicating whether a resource requested by the resource request message is admitted, the RM sends a response message of the resource request message. Therefore, when multicast/unicast connection admission control (CAC) that supports shared bandwidth is realized, flow fusions of user line configuration between the AN and a broadband remote access system (BRAS, and policy distribution between a resource and admission control subsystem (RACS) and the BRAS are guaranteed; and sharing of bandwidth resources is realized to avoid waste of the bandwidth resources.

  • Publication number: 20090194625
    Abstract: Winding cores for elastically stretched or shrinkable materials are designed to significantly reduce the amount of roll strain energy developed during winding. This is accomplished by building into the core an energy-absorbing zone that can be collapsed by a substantial amount and in a relatively controlled fashion over a substantial period of time under the influence of a continued radially inward pressure exerted by the roll of wound material. The energy-absorbing zone is formed by one or more collapsible layers having repeated atomic regions projecting out of a plane of the sheet and each defining a plurality of normal vectors in different sub-regions of the atomic region, wherein the normal vectors, when projected onto the two-dimensional plane of the sheet, are in a plurality of different directions in the plane.

  • Publication number: 20060060008
    Abstract: A test device includes a stationary web roll support assembly comprising a base and a pair of core supports spaced apart and affixed to the base with the core supports projecting upwardly from the base, the core supports structured and arranged to engage opposite ends of a core of a web roll so as to support the web roll. The test device also includes a movable weight load simulating assembly comprising a flexible belt having opposite ends, and a belt holder structured and arranged to secure the opposite ends of the belt to the belt holder with the belt forming a generally U-shaped loop about an outer surface of the web roll intermediate the opposite ends of the core. Movement of the belt holder away from the stationary web roll support assembly causes the belt to exert a load on the web roll, simulating weight load on the core and core supports.
