    Abstract: An automated steering system for an agricultural vehicle operating in a row crop field. The automated steering system includes a correction system having a controller and an alignment sensor. The alignment sensor is disposed between two adjacently spaced crop rows and generates output signals indicative of the alignment sensor's lateral position relative to the two adjacently spaced crop rows as the vehicle advances in the forward direction of travel. The controller receives the generated output signals from the alignment sensor and determines an offset distance of said alignment sensor from a centerline between the two adjacently spaced crop rows. The controller outputs a modified vehicle position signal corresponding to the latitude and longitude position received from said GPS receiver shifted by the offset distance. The vehicle's on board navigation controller causes the vehicles on-board steering control system to steer the vehicle based on the modified vehicle position signal.

  • Patent number: 9172287
    Abstract: A rotary drive includes: a support structure; and a linear actuator supported by the support structure. The linear actuator includes: a first member; a second member that moves in a linear direction relative to the first member when a drive signal is applied to the linear actuator; and a bearing arrangement supporting the first and second members within the support structure and enabling independent movement of the first member and the second member relative to the support structure. The rotary drive also includes a linear-to-rotary converter to which the second member of the linear actuator is coupled. The linear-to-rotary converter includes an output member having a rotational axis. During operation, the linear-to-rotary converter converts linear reciprocating movement of the second member of the linear actuator to rotary movement of the output member about the rotational axis.

  • Patent number: 9118221
    Abstract: The present disclosure relates to a magnetic motor including a drive magnet, a motion magnet, and an acceleration field. The drive magnet includes magnetic shielding, typically on a portion thereof, altering the magnetic field of the drive magnet. In some embodiments, the motion magnet has a cross-section that is generally in the shape of a ‘V’ or ‘A’. The acceleration field is created by the interaction between the drive magnet and the motion magnet as the motion magnet is passed through the altered magnetic field of the drive magnet. The altered magnetic field of the drive magnet may often be near a first end of the drive magnet. In further embodiments, the motion magnet can be operably coupled to an output shaft and rotate around the central axis of the output shaft. The present disclosure, also relates to a device, including the magnetic motor, for generating energy from a turbine.

  • Patent number: 9050907
    Abstract: A rail guide that has at least one rail pair consisting of a floor rail (22) and a seat rail (24). The seat rail (24) has connectors (30) for fastening a seat frame to be arranged above the rail pair. The rails can be moved relative to each other in a longitudinal direction along a movement path (20). The floor rail (22) and the seat rail (24) are curved by the same circular radius of curvature (42) that ranges between 1,500 and 3,000 mm, in particular between 1,800 and 2,500 mm. The center point of curvature (44) is on the side of the rail pair facing away from the seat frame. The rail guide is a longitudinal adjustment device having a stationary spindle (52) and an associated spindle nut (54) that is longitudinally movable thereon, the spindle (52) being curved at the same circular radius of curvature (42). Also described is a suitable method for producing said curved rails by at least one stamping mold (68) or by bending strips (96).
