Title: Method for controlling locomotive operation in tunnel conditions
Inventor: ARMBRUSTER ROBERT A
IPC: B61L23/04
Filed: 2004-10-12
Abstract: A method of controlling operation of a train (T) for passage of the train through a tunnel. The train has a plurality of locomotives (L1-Ln) pulling the train. The position of the lead locomotive relative to the tunnel entrance is determined, as is the amount of time before the train enters the tunnel. Each locomotive is separately configured for passage through the tunnel as a function of performance characteristics of the locomotive and the locomotive's current operating status, as the train approaches the tunnel. Once the train enters the tunnel, the performance characteristics of each locomotive are continually monitored. The performance requirements for one or more of the locomotives are then dynamically changed as a function of conditions within the tunnel and the current performance characteristics of each locomotive.  This is done to maintain a sufficient combined performance capability from the locomotives to move the train through the tunnel. Upon exiting the tunnel, the locomotives' full operating capabilities are quickly restored by enhancing their thermal recoveries.

Abstract: A surgical implant device for treating glaucoma includes an elongate duct structure formed from a material comprising polyisobutylene and a glassy segment. The material of the elongate duct structure preferably has a general block structure with a central elastomeric polyolefinic block and thermoplastic end blocks (e.g., a triblock polymer backbone comprising polystyrene-polyisobutylene-polystyrene). The elongate duct structure provides a fluid passageway for diverting aqueous humor from the anterior chamber of the eye. Preferably, the elongate duct structure defines a lumen channel having an inside diameter between 0.05 mm and 0.3 mm. The material of the elongate duct structure is biocompatible and biostable. Moreover, the material will not encapsulate in the eye and thus provides an unobstructed flowpath that diverts aqueous humor from the anterior chamber. Different embodiments of the implant device divert the aqueous humor to different parts of the eye (e.g., a space between the conjuctiva and sclera, Schlemm's Canal, or a fluid reservoir formed on a posterior surface of the eye).

Inventor: KING JOHN ROBERT
IPC: H04J14/02
Filed: 2005-07-12
Abstract: A method of selecting a wavelength for use in transmitting optical data along a path in an optical network is disclosed. Previously known methods for selecting wavelengths do not consider how a wavelength selection decision will affect future connection attempts along paths that have one or more links in common with the path for which the wavelength is being selection.  Consequently, a future connection attempt may be blocked because there are no wavelengths available end-to-end along the entire path that is to be set up.  In the proposed method, the wavelengths that are available for use end-to-end along the path are found, the wavelengths that are available on each link attached to each node on the path are found and a wavelength that is available end-to-end and that is more available on the links attached to the nodes on the path than other wavelengths is selected.
