    摘要: A vehicle disc brake unit comprises a rotatable brake rotor and non-rotatable brake pad of caliper. During the vehicle braking, the non-rotatable brake pad presses against the rotating brake rotor, producing friction heat on frictional contact bands where the brake rotor and the brake pad engages with each other. A plurality of longitudinal vortex generators configured in fins is mounted either to a rotatable vehicle component such as hat of a brake rotor, or a non-rotatable vehicle component such as a protective plate, generating longitudinal vortices in the cooling air flows around the brake rotor, especially across the hottest frictional contact bands. The induced longitudinal vortices in the cooling air flows optimize the heat dissipation from brake rotor into atmosphere.

    摘要: A two-dimensional locating method of a motion platform based on a magnetic steel array involves the following steps: placing more than four linear Hall sensors at any different positions within one or more polar distances of the magnetic steel array on the surface of the motion platform in a motion system; determining a magnetic flux density distribution model according to the magnetic steel array; determining the mounting positions of the above-mentioned linear Hall sensors, which are converted into phases with respect to the mass center of the motion platform; recording the magnetic flux density measured values of the linear Hall sensors as the motion proceeds; solving the phases of the mass center of the motion platform in a plane, with the measured values being served as observed quantities and the magnetic flux density distribution model being served as a computation model; and determining the position of the mass center of the motion platform with respect to an initial phase according to the phase, so as to realize the planar location of the motion platform. The present invention provides a simple, fast and robust method for computing mass center positions for a motion system containing a magnetic steel array.

    摘要: Using location-independent names to identify content, a service for mapping endpoint requests to requested content. Content requested by an endpoint of the network is mapped to a dynamic “swarm” of server, peer, or other endpoints capable of supporting the content download. Content names are mapped to a dynamically generated content swarm, presenting a current set of hosts, which can provide the requested content. Optionally, varying degrees of explicit visibility into routing paths and the performance tradeoffs between those routing paths is supported. Based on a set of class of service parameters for a given request for content, a host can initiate route selection based on class of service parameters, predicated on routing metrics maintained by the network by cooperating endpoints and/or network routers.

    摘要: An Alternate Current (AC) white Light-Emitting Diode (LED) device is provided, which belongs to the technical field of white LED manufacturing. The problem to be solved by the present invention is to low-costly overcome a series of deficiencies such as the stroboflash of an AC driven LED, and the heat dissipation difficulty caused by an integrated packaging of multiple LEDs. A white LED unit includes an LED chip and a light emitting material that can emit light when being excited by the LED chip. The luminous lifetime of the light emitting material is 1-100 ms. The LED chip only comprises one PN junction. The light emitted by the LED chip is mixed with the light emitted by the light emitting material to form white light. The white LED unit is driven by AC with a frequency not more than 100 Hz. The white LED device of prevent invention uses the single PN junction chip, rather than the prior integrated packaged AC multi-LED chip.
