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: 8198890Abstract: In a method for determining a parameter set describing electric parameters of a route section of a magnetic suspension railway, the route section contains a stator section forming a drive section of the magnetic suspension railway and a route cable connecting the stator section to an associated converter device. In the method, the current and voltage values are measured at the electric connecting point between the route cable and the converter device. The parameters of the parameter set are determined using the measurement values, thus forming the parameter set. Accordingly, the current and voltage values are additionally measured at the electrical connecting point between the route cable and the stator section and the current values at the neutral point side of the stator section, if the stator section is electrically connected to the route cable. The additional measurement values are also considered when determining the parameters.Type: GrantFiled: April 26, 2007Date of Patent: June 12, 2012Assignee: Siemens AktiengesellschaftInventor: Rizqa Derfiora

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.

Patent number: 8085037Abstract: A method for measuring the pole position of a magnetic levitation vehicle in a magnetic levitation railway, wherein a supporting magnetic field is generated on the maglev vehicle as a result of a supporting magnetic current on the vehicle side being fed to at least one supporting magnet. The voltage in the stator on the track is measured and the pole position angle between a reference axis of the stator and a reference axis of the maglev vehicle is determined. The magnitude of the supporting magnetic current on the vehicle side and thus the supporting magnetic field is temporally modified and a voltage induced in the stator by the temporal modification of the magnitude of the supporting magnetic field is detected. The pole position angle is formed using the measured values for the induced voltage.Type: GrantFiled: January 7, 2008Date of Patent: December 27, 2011Assignee: Siemens AktiengesellschaftInventor: Robert Schmid
