Levitation and Propulsion Unit-2 (LPU-2) is a thrust generating device able to generate resultant force to create motion without mass flow and/or momentum exchange. The technology primarily uses electromagnetic energy, permanent magnetic repulsive energy and kinetic energy, to generate internal resultant thrust or motion. This thrust generating device comprises of one or two rapid action enable and high driving force electromagnet moving magnet linear actuators with minimum moving parts. The technology mainly leverages on compression and expansion of compressed repulsive magnetic flux. Through regulation and systematic control of current to each electromagnet, the device is able to generate resultant force or motion without external interaction.

An overhead transport system includes a suspended railway and a motorized carrier configured to travel along the suspended railway. The motorized carrier includes a motorized trolley configured to move the motorized carrier along the suspended railway, chassis/beam configured to carry an object below the motorized trolley, and a bumper and deflection system configured to prevent the object from contacting another object.

A semiconductor device of an embodiment includes a first trench extending in a first direction in a silicon carbide layer; a second trench and a third trench adjacent to each other in the first direction; a first silicon carbide region of n type; a second silicon carbide region of p type on the first silicon carbide region; a third silicon carbide region of n type on the second silicon carbide region; a fourth silicon carbide region of p type between the first silicon carbide region and the second trench; a fifth silicon carbide region of p type between the first silicon carbide region and the third trench; a gate electrode in the first trench; a first electrode, part of which is in the second trench, the first electrode contacting the first silicon carbide region between the fourth silicon carbide region and the fifth silicon carbide region; and a second electrode.

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. The extension continues switching of vehicle direction at the diverge by contacting the septum. Still other aspects of the invention provide a transport system, e.g., as described above, that includes a merge region with a flipper and a broadened region of the running surface. The flipper applies a lateral force to the vehicle to alter an angle thereof as the vehicle enters the merge region, and the broadened region continues the merge by contacting the septum of the vehicle, thereby, providing further guidance or channeling for the merge. The flipper, which can be equipped for full or partial deployment, is partially deployed in order to effect alteration of the vehicle angle as the vehicle enters the merge.

Vehicle guidance system that includes a first guidance bogie selectively positionable in a first position for travel and a second position for direction change and a second guidance bogie selectively positionable in a third position for travel and a fourth position for direction change. At a common crossing, one of: the first guidance bogie is selectively positioned into the second position, or the second guidance bogie is selectively positioned into the fourth position.

A cable transportation system without a hauling cable and comprising: a plurality of transporting units; two supporting cables for supporting the transporting units in a suspended configuration; a plurality of trolleys, wherein each trolley supports a transporting unit in a suspended configuration and comprises rolls configured for resting and rolling on the supporting cables and at least one electric motor configured for moving the trolley along the supporting cables.

A transport system comprising linear motor modules utilized both straight and curved track modules, with movers displaced on the track modules by control of power applied to coils of the modules. Curved track modules have modified spline geometries to provide desired acceleration and jerk characteristics. The modified spline geometries may be defined by more than one generators, such as an equation generator and a spline fit between the equation-generated segment and one or more constrained points or locations. The curved track modules may be divided into 180 degree modules, or may be reduced to 90 degree, 45 degree or other fractional arcs to provide for modular assembly, mirror-image geometries and motion profiles, and the like. The system may be adapted to provide improved motion characteristics based on modification of a conventional spline geometry.

Disclosed is a guide module and a driving device having the guide module. The driving device includes a moving unit mounted on a pinion interacting with a rack and moving with the pinion along a trajectory of the rack, and a guide module arranged at at least any one side of the rack, connected to the moving unit, and guiding a movement of the moving unit that moves with the pinion along the trajectory of the rack.
