Abstract: Two machines, one linear type and one rotative type, rotate some eccentric masses to generate the centrifugal forces, then guide these centrifugal forces into a direction, linear or circular, to extract energy.

Abstract: A hanger with some interlocking cam clips that grip some garments together with the hanger. The clip has a pair of arms hinged together at about their middles by a resilient bar and an interlocking cam joined to one arm's end by cylindrical axles. By pushing the cam into the gap of the arms, the jaws, on the other ends of the arms, close with a clamping force.

Abstract: A method and apparatus for transporting IP datagrams over SONET at a guaranteed quality of service are described. The method utilizes a multi-level bandwidth management hierarchy. A bandwidth allocation manager provides real time high level control of bandwidth allocation in each SONET domain. A bandwidth client at each node in the domain negotiates bandwidth requirements for IP services connected to the node. This enables low error bit rate, scalability and reliable service that can provide guaranteed quality of service for IP applications. All aspects of connection setup, bandwidth allocation, bandwidth size adjustment and connection termination are negotiated by the bandwidth client with the bandwidth allocation manager. Multiple domains can be interconnected to form larger networks providing reliable connections at a guaranteed QOS.
