Abstract: Systems and methods are described for supporting routing intelligence for evaluating routing paths based on performance measurements. The routing intelligence may include processes executed in a self-contained device. This device may control one or more edge routers, based on performance data from end users. In other embodiments, the routing intelligence device may be used solely to monitor one or more edge routers, producing reports but not effecting any changes to routing. Routing decisions may be injected to the edge routers via BGP updates. The devices may be stationed at the premises of a multihomed organization, such as an enterprise, ISP, government organization, university, or other organization supporting a sub-network coupled to an internetwork. In other embodiments, the routing intelligence comprises processes executed on a router.

Abstract: Systems and methods are described for enabling routers to coordinate via a back-channel communication medium. The information exchanged over the back-channel is used to increase the number of paths considered for the routers during route optimization. The Decision Makers may assert routes and prefixes to the routers under their control. This may be done via a Border Gateway Protocol (BGP) feed. The Decision Makers, in turn, communicate separately with one another, in order to coordinate routing policy amongst themselves. This coordination may be performed over a back-channel, which may take the form of physical or logical connections between the Decision Makers.

Abstract: The present invention is directed to computerized vehicle servicing and diagnostic systems that communicate with or access remotely located computers via the Internet that have pre-stored data or utilize pre-store data and parameters. The present system provides a navigational framework with two modules, the Menu Mode (random) and the Wizard Mode (sequential). The Menu Mode provides direct access to any required process and Wizard Mode provides a flexible control of process sequences and allows for user modification.

Abstract: A pharmaceutical composition for the nasal delivery of compounds useful for treating osteoporosis, comprising an effective amount of a physiologically active truncated analog of PTH or PTHrp, or salt thereof, in which amino acid residues (22-31) form an amphipathic .alpha.-helix, said residues (22-31) selected from (SEQ ID NOS: 85, 86, 26, 27, 28, 29, and 30); an absorption enhancer selected from the group consisting of dimethyl-.beta.-cyclodextrin and the bile acid surfactants; and water is provided.

Abstract: A method for the automatic sharp separation and removal of layers of fluids from a container through a headspace in the container comprises the use of two separate and simultaneous flow streams to draw fluid from the upper layer as the apparatus descends in the fluids. The entry of the lower fluid into the apparatus is detected as a result of the different physical properties of the lower fluid by which the apparatus is caused to stop its descent into the fluid and to interrupt the flow of fluid through one of the flowsteams. The flow of the flowstream is interrupted by the entry of a gas into that stream. The apparatus is subsequently lowered into the remaining fluid and the withdrawal of the fluid through the apparatus is begun again.

Abstract: A coal fired power plant includes a coal gasification zone where coal is gasified in the presence of an oxidant-lean atmosphere under partial coal gasifying conditions to produce a carbonaceous char and a crude gas stream, an acid separating zone where sulfur-containing compounds are separated from the crude gas stream to produce a combustible gas stream, and a converting zone where the sulfur-containing compounds are converted to elemental sulfur. The combustible gas stream and the carbonaceous char are fed into a boiler which drives a generator to produce electricity; portions of the carbonaceous char product and the combustible gas stream are diverted into a gypsum desulfurization zone. SO.sub.2 -containing flue gas from the boiler is fed into a flue gas desulfurization zone. There, the SO.sub.2 -containing flue gas is contacted with lime and limestone to produce gypsum.

Abstract: A wheel chair motor control circuit for a wheel chair having two independently controllable motor-driven wheels. The user has a "joystick" control operable from a datum position to move the wipers of two potentiometers both independently and simultaneously from their corresponding datum positions. A first, proportional control circuit is provided for each motor to supply it with drive power proportional to the magnitude of the deviation of its corresponding potentiometer wiper from datum and a second reversing circuit is provided for each motor to operate a reversing relay connected thereto in accordance to the direction of the deviation of its corresponding potentiometer wiper.
