Expandable Wheel Body Patents (Class 301/16)
  • Patent number: 11454737
    Abstract: Disclosed is a method for predicting the future magnetic alignment of a runway. Extrapolating from previous historical records, the future trajectory of the Earth's eccentric geomagnetic axial pole (“ED”) is predicted. With that predicted trajectory as the basis, the future azimuthal change between the location of the ED and the location of an airfield is calculated. At the location of the airfield, a future change in the declination between true north and geomagnetic north is then calculated based on the predicted azimuthal change. The predicted change in declination then becomes the predicted change in magnetic alignment of any runway at the airfield. By predicting future changes in the magnetic alignment of a runway, preparations for changing the name of the runway can be made.

  • Patent number: 10352721
    Abstract: A device can determine route information associated with a route of a vehicle. The device can identify, based on the route information, feature data associated with the route of the vehicle. The device can determine, based on the feature data, notification information associated with a feature on the route of the vehicle. The feature can include at least one of: a passing zone on the route of the vehicle, a school zone on the route of the vehicle, a potential roadway hazard on the route of the vehicle, a segment of the route with a speed limit that is different from a speed limit of another segment of the route, or a segment of the route with a number of lanes that is different from a speed limit of another segment of the route. The device can provide the notification information associated with the feature.

  • Patent number: 7963618
    Abstract: There is presented a system and method for providing aircraft runway guidance. One delineated runway alert system for a host aircraft comprises: a processor for executing one or more instructions that implement one or more functions of the runway alert system; a data storage device including geographical runway information; a receiver for obtaining current location data of the host aircraft; an apparatus to provide a current heading of the host aircraft; a data entry device for receiving data indicating a desired runway; memory for storing the one or more instructions for execution by the processor to implement the one or more functions of the runway alert system to: receive the identity of the desired runway; provide an indicia of: the desired runway; and the position of the host aircraft in relation to the desired runway.

  • Patent number: 7416261
    Abstract: The quick-change adjustable track center front hub assembly is secured to a spindle axle of a sprint car by a friction drive bearing system located between the spindle axle and the front hub assembly. The bearings are spaced apart to provide increased side and torsional load carrying capability. In addition, the hub includes a section of external splines for accepting at least one spacer and a wheel center section both having internal splines for mating with the external splines on the hub. A single lug nut connects to the outboard end of the hub for securing the spacers and wheel center sections to the front hub assembly to provide a quick-change arrangement not found before in sprint-type cars. A brake rotor is attached to the hub inboard of the spacers and wheel center section, thus allowing unimpaired accessibility to the wheel center section and spacers for quick-changing and adjusting the track center of the front wheels of the sprint-type cars.

  • Patent number: 5839795
    Abstract: A variable outer diameter wheel includes a generally cylindrical pipe or drum having four equally spaced penetrating holes or receiving parts in the cylindrical wall, a diaphragm sealing member corresponding to each of the penetrating holes and fitted to the pipe support, and sliders forming a wheel peripheral face so that the sliders can smoothly slide in the penetrating holes. The sliders are pushed or activated and moved outward from the pipe in a direction so the wheel outer diameter is enlarged by compressed air supplied through a passage and a hole provided in an axle which support the wheel. Exhausting the compressed air causes the wheel outer diameter to decrease and restores the wheel to its original size. Variable outer diameter wheels permit safe operation of vehicles on frozen, snow-clad or irregular surfaced roads.

  • Patent number: 4178042
    Abstract: Agricultural tractors having variable-track wheels for working in different conditions, particularly in row-crops, are known. The track-width of their driving wheels has sometimes been made power-adjustable by fixing brackets having respective grooves on the periphery of each hub and releasably clamping the brackets to respective helical rails fixed inside each rim and engaging the grooves. Due to the increasing size and power of tractors, and also to eventual wear of the components, it is difficult to achieve effective clamping. In an attempt to solve the problem, shims have been inserted where necessary between the brackets and the periphery of each hub. It is now proposed to solve the problem more positively by providing at least some of the brackets of each wheel with screws by which the brackets so provided can be adjusted in position radially of the hub before being fixed thereto.
