Systems, apparatus, and methods may control movement of an object through a fluid. The systems, apparatus, and methods may utilize a rotatable control unit including a pair of fins to generate a control force at least partially perpendicular to a direction of travel of the object through the fluid. One fin may be configured to generate a different amount of rolling moment than the other fin to provide rotational acceleration and energy production.

Drogue control systems and apparatus

Systems, apparatus, and methods may control movement of an object through a fluid. The systems, apparatus, and methods may utilize one or more rotatable control units, each including a plurality of control fins to generate a force at least partially perpendicular to a direction of travel of the object through the fluid.

The gathering, conveyance, and assembly of printed material utilizing one or more aerodynamic positioning devices in conjunction with binding machinery is disclosed. The aerodynamic positioning device utilizes controlled fluid flow via a series of discretely spaced jets that create a low pressure region beneath a signature dropping from an adjacent feeder. The aerodynamic positioning device allows the binding machinery to operate at high speeds with lightweight and unbalanced signatures while maintaining high-quality production with reduced paper jams.
