  • Publication number: 20110002989
    Abstract: The present invention provides methods, dosage forms and kits for treating with an effective amount of ziprasidone a CNS disorder in a human when the human is in a fasted state. In one embodiment, the invention relates to a method for treating a CNS disorder in a human, which method comprises administering to the human in a fasted state, a solid oral dosage form comprising an amount of ziprasidone effective to treat said CNS disorder, wherein the area under the serum concentration versus time curve (AUC0-inf) of the ziprasidone in the human subsequent to said administering is from 70% to 140% of the mean area under the ziprasidone serum concentration versus time curve (AUC0-inf) resulting from administration of a control ziprasidone immediate release oral capsule containing the same amount of ziprasidone to a cohort of humans in a fed state.

  • Publication number: 20100168976
    Abstract: A method and system are provided for controlling overspeeding of a vehicle carrying an internal combustion engine having one or more exhaust brake devices controllable to apply braking torque to the engine. The system may be operable determine a desired speed of the vehicle, to determine a road speed of the vehicle, and if the road speed of the vehicle exceeds the desired speed of the vehicle by more than a threshold speed, to determine a target brake torque required to reduce the road speed of the vehicle speed to the desired speed of the vehicle, and to then control the one or more exhaust brake devices to apply the target brake torque to the engine to thereby control the road speed of the vehicle to the desired speed of the vehicle.

  • Patent number: 7535831
    Abstract: A method for providing grades of service to unprotected traffic on an optical network that provides protection channels associated with working channels, defines a linearly ordered set of protection switch request priorities, and two or more grade of service priorities, and uses those priorities to enforce a protection access policy. The unprotected traffic may be of a high priority, approximating non-pre-emptable unprotected traffic (NUT); of low priority, like extra traffic; or may be of an intermediate priority between the two. This allows data transport providers to offer different unprotected transport services at different rates on protected links, in which the different unprotected transport services are associated with different probabilities of pre-emption.

  • Publication number: 20050088963
    Abstract: A method for processing automatic protection switch (APS) messages at a network element in a tunnel provisioned across a data transport network in order to provide for distributed processing of protection switch request messages involves receiving new APS message at the NE; determining whether the NE is an end point of the tunnel, or a tandem of the tunnel and processing the message accordingly. If the NE is a tandem, message processing involves using local information about tunnel segments of the tunnel only maintained by the NE, to update the local information, and to selectively forward the updated information to adjacent NEs of the tunnel. If the NE is an end point, it updates a status of the tunnel. In a preferred embodiment all NEs are responsible for controlling pending and preemption indicators, and for initiating tunnel condition messages, and the end point NEs are responsible for initiating all other messages.

  • Publication number: 20050058060
    Abstract: A method for permitting a network element to transmit to a second network element a message over a link, that identifies a tunnel segment occupying predefined proportion of the data transport on the link, and a status of the tunnel, so that each tunnel may be provided with independent protection switching messaging involves providing an identifying scheme for locally identifying the tunnels passing through the tunnel segment. In order to permit this information to be sent over existing (narrow) automatic protection switching (APS) channels, the identifying scheme only provides a local identifier of the tunnel. To permit extended messaging to include messages that do not fit in a single K-byte overhead, extension bits are used to identify continuation of a message across multiple frames.

  • Patent number: 5338571
    Abstract: A method is provided for forming a fullerene layer on a substrate by chemically treating a surface of the substrate to provide a bond-forming species at the surface effective to covalently bond with fullerenes in solution and contacting the treated substrate surface with a solution of fullerenes to form a fullerene layer covalently bonded to the treated substrate surface. Alternately or in addition, a fullerene layer is formed on a substrate by chemically modifying fullerenes to provide a bond-forming species thereon, chemically treating a surface of the substrate to provide a bond-forming species effective to covalently bond with the bond-forming species of the fullerenes in solution, and contacting a solution of treated fullerenes with the treated substrate surface to form a fullerene layer covalently bonded to the treated substrate surface.
