  • Patent number: 8891547
    Abstract: The present invention discloses a link scanning method for cascaded RCUs and a remote electrical tilt antenna system. The method includes: receiving, a link scanning message and sending the link scanning message to the RCU in the next cascaded RCU; generating, a link scanning response message, sending the link scanning response message to the RCU in the preceding cascaded RCU, and reporting the link scanning response message to the CCU, and sending, the link scanning message to the CCU. In the present invention, by adding a time delay in the link of the remote end serial communication bus, each RCU does not respond to the link scanning message simultaneously, the time-delayed link scanning response messages in the link of the remote end serial communication bus of each RCU are not aliased, therefore, the bus conflict problem of the link scanning when the RCUs are cascaded is effectively solved.

  • Publication number: 20140305849
    Abstract: The present application provides a magnetic rack for separating magnetic particles from a non-magnetic medium. The magnetic rack comprises a supporting housing having a top side, a bottom side, two opposite lengthwise sides, and a cavity, wherein at least one magnet is disposed in the cavity, each lengthwise side is attached with a receiving member, and the top side has at least two sockets. The magnetic rack further comprises a pair of supporting walls, wherein each supporting wall has a fixing member introduced onto or into the receiving member to tightly connect the supporting housing with the pair of supporting walls. With the coupling of the receiving member and the fixing member, the supporting wall and the supporting housing can be tightly connected together, therefore the shake of the magnetic rack or the sample vials inserted in the magnetic rack can be significantly avoided. In this way, the magnetic particles can be effectively separated from a non-magnetic medium in the sample vial.

  • Patent number: 8852359
    Abstract: A method of bonding a metal to a substrate involves forming an oxide layer on a surface of the substrate, and in a molten state, over-casting the metal on the substrate surface. The over-casting drives a reaction at an interface between the over-cast metal and the oxide layer to form another oxide. The other oxide binds the metal to the substrate surface upon solidification of the over-cast metal.
