20140182478 | TRANSPORT SYSTEM POWERED BY SHORT BLOCK LINEAR SYNCHRONOUS MOTORS - Aspects of the invention provide a transport system powered by short block Linear Synchronous Motors (LSMs). The use of short blocks allows vehicles to move under precise control even when they are in close proximity to each other. The design allows the vehicles to be propelled and guided while negotiating sharp turns and negotiating merge and diverge switches. A coreless LSM can be used to create propulsive force without attractive force so as to allow a relatively high drag vehicle suspension, such as a vehicle sliding on a smooth surface. | 07-03-2014 |
20130074724 | Transport system powered by short block linear synchronous motors and switching mechanism - The invention provides in some aspects a transport system comprising a guideway with a plurality of propulsion coils disposed along a region in which one or more vehicles are to be propelled. One or more vehicles are disposed on the guideway, each including a magnetic flux source. The guideway has one or more running surfaces that support the vehicles and along which they roll or slide. Each vehicle can have a septum portion of narrowed cross-section that is coupled to one or more body portions of the vehicle. The guideway includes a diverge region that has a flipper and an extension of the running surface at a vertex of the diverge. The flipper initiates switching of vehicle direction at a diverge by exerting a laterally directed force thereon. | 03-28-2013 |
20130008336 | Versatile Control of a Linear Synchronous Motor Propulsion System - Control of Linear Synchronous Motors involves a number of low level issues of motor control—such as sensing precise position, controlling current in stator windings, and obeying commands from high level controllers—and high level vehicle control—such as stopping and starting, switching and merging, limiting speed and acceleration, synchronizing relative motion, preventing collisions and accidents, and dealing with failures. In most cases there is a master controller that directs vehicles based on simple commands but in other cases it is desirable to allow an external agent to provide more detailed control—such as synchronizing motion between a vehicle and a robot or allowing human operator control. This patent describes a versatile control scheme that allows both simplified high level control and, when or where necessary, control by an external agent. The result is a transport system and method that provides efficient and precise movement of vehicles on a guideway. | 01-10-2013 |
20100236445 | TRANSPORT SYSTEM POWERED BY SHORT BLOCK LINEAR SYNCHRONOUS MOTORS AND SWITCHING MECHANISM - Aspects of the invention provide a transport system powered by short block Linear Synchronous Motors (LSMs). The use of short blocks allows vehicles to move under precise control even when they are in close proximity to each other. The design allows the vehicles to be propelled and guided while negotiating sharp turns and negotiating merge and diverge switches. A coreless LSM can be used to create propulsive force without attractive force so as to allow a relatively high drag vehicle suspension, such as a vehicle sliding on a smooth surface. Further aspects of the invention provide a switching member that is selectively moveable relative to a guideway in order to change a magnetic force acting on the vehicle transverse to a direction of motion of the vehicle. | 09-23-2010 |

20090107806 | THREE-DIMENSIONAL MOTION USING SINGLE-PATHWAY BASED ACTUATORS - The invention provides novel mechanisms and methods for effecting rotational and translational motion in three dimensions of objects carried by, or coupled to, actuators that move along a pathway. Vehicles or other conveyances (collectively, “vehicles”) that utilize mechanisms and methods can increase the performance of and decrease the cost of transportation, shipping, manufacturing, materials handling and other systems. In one aspect, the illustrated embodiment provides such a vehicle or other conveyance having two (or more) actuators adapted for movement along a pathway. The actuators are propelled or otherwise capable of motion, relative to each other so that the distance between can be increased or decreased. When desired, that distance can also be maintained the same, e.g., regardless of whether the actuators are moving. A pallet, carriage or other moveable part (collectively, pallet) is moveably coupled to the actuators so that at least selected motions by the actuators relative to one another on the pathway effect rotational and/or translational motion of the pallet in three dimensions relative to the pathway, including, for example, movement transverse to the pathway and out of a plane of the pathway. | 04-30-2009 |
