Patent number: 8499697Abstract: A system and method are provided for determining the position of a vehicle on a guideway. For operation, the vehicle includes a magnet system having a wavelength “?”. Further, the guideway includes a propulsion winding for carrying a propulsion current. Structurally, the propulsion winding includes a series of sections, with each section having a wavelength “?”. Further, the propulsion winding includes “N” coils linearly aligned along the guideway, with a phase difference of “?/N” between adjacent coils. Importantly, a transmitter is located on the vehicle for emitting a position current that interacts with the propulsion winding to produce a signal in each coil. Also, the system includes a trap connected to each coil for receiving each respective signal, and a processor for resolving the respective signals to determine the position of the vehicle on the guideway.Type: GrantFiled: February 20, 2009Date of Patent: August 6, 2013Assignee: General AtomicsInventors: Bogdan S.

Patent number: 8221024Abstract: A method of constructing a roadway having an embedded linear synchronous motor (LSM) utilizes prefabricated modules. Structurally, each module comprises a top plate, a multiple-phase winding tied to the top plate, and a concrete mold encapsulating the winding. With the modules prefabricated, the roadway is constructed by first excavating a trench to position a foundation at the trench bottom. Then a mud matt is positioned on the foundation. Next, the modules are laid end-to-end on the mud matt. Thereafter, the windings in adjacent modules are electrically interconnected through joints. Further, the joints are covered by junction boxes, and the trench around the roadway is filled in with aggregate.Type: GrantFiled: September 3, 2009Date of Patent: July 17, 2012Assignee: General AtomicsInventors: Philip L. Jeter, Husam Gurol, In-Kun Kim

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: 8113310Abstract: An all-electric, wheeled vehicle has a magnet array that can be selectively moved between a retracted position and a deployed position, to respectively operate in a motor mode or a generator mode. When in the motor mode, with its magnet array retracted, wheel rotation to move the vehicle is powered by an onboard battery. Alternately, in the generator mode with the magnet array deployed, the vehicle is powered by a Linear Synchronous Motor (LSM). Specifically, the deployed magnet array interacts with a multiple-phase winding (i.e. LSM) embedded into the roadway on which the vehicle travels. Further, rotation of the wheel during vehicle movement in the generator mode recharges the battery.Type: GrantFiled: February 12, 2009Date of Patent: February 14, 2012Assignee: General AtomicsInventors: Husam Gurol, Philip L.

Patent number: 8109353Abstract: A system and method are provided for moving a vehicle along a roadway. The system includes at least one power segment that incorporates a multiple-phase winding. Structurally, the winding is embedded into the roadway for interaction with a magnet system mounted on the vehicle. With this interaction, a Linear Synchronous Motor (LSM) is established between the roadway and the vehicle to drive movement of the vehicle along the roadway. Also, the vehicle includes a mechanism for initially synchronizing a waveform speed of the multiple-phase winding with the speed of the vehicle. Further, the vehicle is able to selectively establish the LSM for use when desired.Type: GrantFiled: April 2, 2009Date of Patent: February 7, 2012Assignee: General AtomicsInventors: Husam Gurol, Philip L.

Patent number: 7255046Abstract: The present embodiments provide methods and apparatuses for use in controlling and directing magnetically levitated vehicles. In some embodiments, a method propels or passes a vehicle along a guideway, magnetically levitates the vehicle as it travels along the guideway, and induces a magnetic drag on the vehicle as it travels along a portion of the guideway. The magnetic drag can be induced by passing the magnet proximate a plate of conductive material. The plate can be positioned on a first side of the vehicle to induce the magnetic drag resulting in a force on the vehicle in a direction toward the first side. The method can further induce the magnetic drag to guide the vehicle along a curve of the guideway, where the plate is positioned on an inward side of the curve such that the force directs the vehicle into the curve.Type: GrantFiled: July 23, 2004Date of Patent: August 14, 2007Assignee: General AtomicsInventors: Robert W.

Patent number: 5479144Abstract: A method and apparatus for correcting harmonics (multipoles) in high energy particle accelerators using superconducting magnets using corrector rods adjacent to accelerator magnets. In such accelerators, superconducting coils are positioned around a non-magnetic beam tube with the magnetic coils designed to guide particles, such as protons, along the tube. Magnetic field non-uniformites in the form of multipoles (harmonics) will disrupt the beam guidance, causing particles to hit the tube walls and be lost, reducing accelerator efficiency. The negative effects of multipoles (harmonics) in such accelerators can be reduced or eliminated by positioning a selected number of pairs of carefully sized and dimensioned rods of magnetic material such as nickel or iron along the exterior of the beam tube or enclosing helium vessel near the magnet ends. The rods are equally spaced and lie parallel to the beam tube axis.Type: GrantFiled: October 1, 1993Date of Patent: December 26, 1995Assignee: Martin Marietta CorporationInventor: Husam Gurol

Patent number: 5389907Abstract: A method and apparatus for correcting harmonics (multipoles) in high energy particle accelerators using superconducting magnets using a pattern of superconducting bands adjacent to the accelerator magnets. In such accelerators, superconducting coils are positioned around a non-magnetic beam tube with the magnetic coils designed to guide particles, such as protons, along the tube. Magnetic field non-uniformities in the form of multipole harmonics will disrupt the beam guidance, causing particles to hit the tube walls and be lost, reducing accelerator efficiency. The negative effects of multipoles (harmonics) in such accelerators can be reduced or eliminated by positioning a non-magnetic tube bearing a pattern of longitudinal superconducting bands, connected by circumferential band segments around the exterior of the helium vessel or other suitable surface near the magnet ends. The bands are formed from a superconductor having a critical temperature above the boiling temperature of liquid nitrogen.Type: GrantFiled: October 7, 1993Date of Patent: February 14, 1995Assignee: General Dynamics CorporationInventors: Husam Gurol, Robert W.
