Patent number: 8224509Abstract: A system for controlling movements of a vehicle along a guideway includes an array of targets that are mounted on the vehicle, and a series of wayside sensors that are mounted on the guideway. A signal processor monitors the passage of targets past appropriate sensors and uses resultant signals to derive parametric values that are characteristic of the vehicle's movements. The parametric values are then coordinated with a controller for the operation of a linear synchronous motor that propels the vehicle.Type: GrantFiled: August 22, 2007Date of Patent: July 17, 2012Assignee: General AtomicsInventors: Philip Lynn Jeter, Karoly Kehrer, Husam Gurol

Patent number: 8171858Abstract: 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.Type: GrantFiled: December 19, 2007Date of Patent: May 8, 2012Assignee: Advanced Maglev Systems, LLCInventors: John Lee Wamble, III, Christopher Perkins, John V.

Publication number: 20110271867Abstract: The invention relates to a linear permanent magnet driving system and a permanent magnet driving maglev train rail system, the linear permanent magnet driving system comprises spiral rotors and stators, wherein at least one of the spiral rotor and the stator adopts the structure having a permanent magnet while the other one adopts the structure having the permanent magnet or a magnetizer; when the spiral rotors are driven by an engine to rotate, linear motion of the spiral rotors is achieved by means of the magnetic force between both, and speed of the linear motion of the spiral rotors can reach supersonic speed at most. By applying the linear permanent magnet driving system to the permanent magnet driving maglev train rail system, the entire rail can avoid the use of both permanent magnet and driving coil, and the construction cost of maglev train rail is equivalent to that of the current high-speed wheel/rail.Type: ApplicationFiled: August 23, 2009Publication date: November 10, 2011Inventor: Zhongchen Liu
