Method and apparatus for controlling web tension by actively controlling velocity and acceleration of a dancer roll
InactiveUS6314333B1The result is accurateAutomatic control devicesPrecision positioning equipmentControl systemEngineering
This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to controlling tension in such continuous webs during the processing operation. Tension is controlled in a dancer control system by connecting a corresponding dancer roll to an actuator apparatus or the like, sensing variables such as position, tension, velocity, and acceleration parameters related to the web and the dancer roll, and providing active force commands, in response to the sensed variables, to cause translational movement, generally including a target acceleration, in the dancer roll to control tension disturbances in the web. In some applications of the invention, the dancer control system is used to attenuate tension disturbances. In other applications of the invention, the dancer control system is used to create tension disturbances.

Quiet vertical takeoff and landing aircraft using ducted, magnetic induction air-impeller rotors
InactiveUS7032861B2Improve performanceImprove stabilityAircraft navigation controlUnmanned aerial vehiclesFlight control modesRudder
A hover aircraft employs an air impeller engine having an air channel duct and a rotor with outer ends of its blades fixed to an annular impeller disk that is driven by magnetic induction elements arrayed in the air channel duct. The air-impeller engine is arranged vertically in the aircraft frame to provide vertical thrust for vertical takeoff and landing. Preferably, the air-impeller engine employs dual, coaxial, contra-rotating rotors for increased thrust and gyroscopic stability. An air vane assembly directs a portion of the air thrust output at a desired angle to provide a horizontal thrust component for flight maneuvering or translation movement. The aircraft can employ a single engine in an annular fuselage, two engines on a longitudinal fuselage chassis, three engines in a triangular arrangement for forward flight stability, or other multiple engine arrangements in a symmetric, balanced configuration. Other flight control mechanisms may be employed, including side winglets, an overhead wing, and / or air rudders or flaps. An integrated flight control system can be used to operate the various flight control mechanisms. Electric power is supplied to the magnetic induction drives by high-capacity lightweight batteries or fuel cells. The hover aircraft is especially well suited for applications requiring VTOL deployment, hover operation for quiet surveillance, maneuvering in close air spaces, and long duration flights for continuous surveillance of ground targets and important facilities requiring constant monitoring.

Seating with shape-changing back support frame
A back includes an integrated articulating back frame and a back support. The back frame has a lower segment pivoted to a chair control, an upper segment for thoracic support, and links forming a four-bar linkage with the upper and lower segments, with a joint being formed at the lumbar region. The back support is stretchable in limited directions to accommodate shape change in the articulating back frame but to provide adequate support to a seated user. Upon receiving a rearward pressure on the lumbar joint, the back frame itself changes shape. The pivot locations in the four bar linkage create a mechanism that simultaneously controls rotational and translational movement of the upper segment during flexure of the lumbar. The back frame is close to the back support to provide significant design flexibility, but permit substantial lumbar flexure. Various back supports are contemplated that accommodate articulation of the back frame.

The second end of one link of each set of links is pivotally pinned to the actuator and the second end of the other link of each set of links is pivotally pinned to the hub. Rotation of the actuator relative to the hub controls the arcuate separation of these second ends such that bringing these second ends toward contiguity moves the segments radially outwardly, and conversely, moving these second ends arcuately apart serves to move the segments radially inwardly of the drum. A hand wheel establishes maximum and minimum rotational movement of the actuator and provides a visual indication of the radial positions of the several segments, i.e. the diameter of the drum.
