Filed:

Dec 19, 2007

Appl. No.:

11/960605

Inventors:

Christopher Perkins - Westlake Village CA, US
John V. Cole - Laguna Miguel CA, US
Clark Foster - Mission Viejo CA, US

Assignee:

Advanced Maglev Systems, LLC - Shoreline WA

International Classification:

B60L 13/04

US Classification:

104281, 104282, 104283, 104284

Abstract:

The networked guideway transit system uses materials and methods of constructing guideway elements. The materials and methods are designed to reduce the static weight, cost and physical size of the guideway structure. Installation cost is also significantly reduced by the modular nature of the guideway components, which can be manufactured in a controlled factory environment using mass production methods. As a result, the supporting structure of the guideway can be quickly erected and the modular blocks inserted with simple equipment. In addition, complex alignment procedures are not required. In particular, the guideway component includes motor coils having the shapes and configurations that facilitate the easy insertion of the guideway component without the need for interleaving coils in adjacent guideway components and without creating dead spots in the magnetic fields between guideway components.

International Classification:

G06K009/00

US Classification:

382/154000

Abstract:

A method and system for processing stereoscopic images includes a computer program operable to acquire stereoscopic data from image sensors. The computer program is further operable to process the stereoscopic data from image sensors into output that can be satisfactorily resolved by human vision.

International Classification:

F03D 9/00
H02K 7/09
H02K 7/18

US Classification:

290 44, 290 52, 290 55, 310 905

Abstract:

An electric power generation system may be constructed of multiple similar generator modules arranged between a rotor and a stator. The rotor may be coupled to and/or integrated with a turbine that is configured to rotate in the presence of a fluid stream such as wind or water. Each generator module may have a rotor portion configured to generate a magnetic field having at least one characteristic that changes with respect to the rotational speed of the rotor. Each generator module may further have a stator portion configured to generate an alternating electric current responsive to the magnetic field. The generated electric current may be controlled by the stator portion of the generator module in order to magnetically control the rotational speed of the rotor and the turbine. Separation between the rotor and stator portions of the generator module may be magnetically maintained.
