  • Patent number: 6520735
    Abstract: An autonomous remote controlled vehicle for use in the automation of an existing refrigerated flow through storage facility food processing application. The remote vehicle is specifically designed to operate within a network of centrally controlled remote vehicles that are adapted to receive selectable items from production and temporarily store them for later retrieval. The system is adapted to minimize travel time for the remote vehicle and optimize cycle time. The system is specifically adapted to handle cardboard shipping boxes containing meat products.

  • Patent number: 5319273
    Abstract: A fixed gain electromagnetic actuator for controlling the position of a body including at least two pair of a magnetically permeable pole spaced from the body, bias coils about each pole, separate control coils about each pole, a bias source for the bias coils providing a current in the bias coils producing a steady-state equal strength magnetic field on opposing sides of a body, and a control source for the control coils providing a current in the control coils for producing an increase in the magnetic field on one side of the body and a corresponding equivalent decrease in the magnetic field on the opposing side of the body to compensate for any external upsetting forces acting on the body.

  • Patent number: 4961352
    Abstract: A magnetic rotor suspension system including a magnetic rotor having a spin axis, and a generally spherical housing spaced from the rotor. The system includes means attached to the housing for applying magnetic fields to the rotor to fix its lateral and axial position relative to the housing and to adjust the angular orientation of the spin axis of the rotor relative to the housing.

  • Patent number: 4900962
    Abstract: A magnetic bearing system for enabling translational motion includes a carriage and a shaft for movably supporting the carriage; a first magnetic bearing fixed to one of the carriage and shaft and slidably received in a first channel of the other of the carriage and shaft. The first channel is generally "U" shaped with two side walls and a back wall. The magnetic bearing includes a pair of spaced magnetic pole pieces, each pole piece having a pair of electromagnetic coils mounted on poles on opposite ends of the pole piece proximate the side walls, and a third electromagnetic coil mounted on a pole of the pole piece proximate the backwall; a motion sensor for sensing translational motion along two axes and rotationally about three axes of the carriage and shaft relative to each other; and a correction circuit responsive to the sensor for generating a correction signal to drive the coils to compensate for any misalignment sensed between the carriage and the shaft.

  • Patent number: 4785212
    Abstract: A magnetic suspension system for a rotary machine including two magnetic actuators spaced from each other. Each actuator includes a stator which has a support shell with a plurality of coil windings, and a rotor which has an inclined annular gap for rotatably receiving the shell and a device for providing a magnetic field in the gap. The system selectively excites the coils to interact with the magnetic field in each gap and produce Lorentz forces for suspending the rotor of each actuator.

  • Patent number: 4723735
    Abstract: An energy storage attitude control and reference system for a craft including at least two flywheels with their angular momenta balanced to produce zero net angular momentum and at least two motor/generator units each including one of the flywheels in its rotor structure. The system further includes one pair of bearings for supporting each of the flywheels, means for measuring the position of each flywheel relative to its bearings, means for resolving current to and from said motor/generator units, means for applying torques to each flywheel through its respective bearings for controlling attitude of the craft about two mutually perpendicular axes, and means for exerting torques to each flywheel through its respective motor/generator to provide attitude control of the craft about a third axis perpendicular to the first two and for controlling the energy storage level of the flywheels.

  • Patent number: 4700094
    Abstract: A magnetic suspension system including a first control coil for establishing circumferential current flow, and second and third control coils for establishing axial current flow. A support member of magnetic material has a gap for receiving the coils and there is a magnet for producing a magnetic field in the support member through the gap in the coils for generating Lorentz forces to support the coils in the axial and two mutually perpendicular radial directions.
