    Abstract: According to one embodiment, a constant velocity (CV) joint includes a first yoke, a second yoke, and three bearings. The first yoke is configured to be rotatably coupled to an input device about a first axis and configured to receive the input device through a first opening. The second yoke is rotatably coupled to the first yoke about a second axis and rotatably coupled to an output device about a third axis. The first bearing is disposed about the first axis adjacent to the first yoke, the second bearing is disposed about the second axis adjacent to the first yoke or the second yoke, and the third bearing disposed about the third axis adjacent to the second yoke. The first and third bearings torsionally constrain movement the first yoke and the second yoke so as to achieve a substantially CV characteristic between the input device and the output device.

    Abstract: The present application relates to a system and method for providing real-time indications of economic impact of aircraft operations to an aircraft operator. The system and method allow the aircraft operator to reduce economic impact during flight of the aircraft. Such an analysis and cue to the aircraft operator allows the operator to make real-time changes during flight to reduce damage of life-limited aircraft components, thereby reducing the economic impact of aircraft operation that is directly associated with maintenance and component replacement. The system and method can also include pre-flight and post-flight analysis methods for reduction of economic impact of flight operations.

    Abstract: A bi-directional drive system for turf grooming and brushing operations includes first and second accessory attachment assemblies connected to a reel deck assembly. A first drive housing connected to the first accessory attachment assembly has a first positive engagement drive member rotatable with respect to the first drive housing. A second drive housing connected to the second accessory attachment assembly has a second positive engagement drive member rotatable with respect to the second drive housing. An attachment member is releasably connected to each of the first and second positive engagement drive members and axially rotated in either a first or an opposite second axial rotation direction. First and second fasteners individually received through one of the first or second positive engagement drive members releasably couple the attachment member to the first and second positive engagement drive members. Attachment member removal is provided by releasing only the first and second fasteners.
