Abstract: The present disclosure relates to snowboards and skis that include a pair of edges for each longitudinal side of the snowboard or ski. The edges are laterally spaced apart, with one edge being an outer edge and the other edge being an inner edge. The inner edge is positioned vertically lower than the outer edge. The inner edge generally engages the snow surface prior to the outer edge, and is thus a transitional edge. Transitional edges may be rounded edges. The top surface of dual-edges snowboards or ski include an inner portion flanked on each lateral side by a lateral offset. A portion of the inner portion is recessed relative to the lateral offsets. The outer edges are positioned on a base surface of the lateral offsets. The inner edges are positioned on a base surface that is below the interface between the lateral offsets and the inner portion.

In one embodiment, the strength training apparatus includes a base member and a tower structure coupled with the base member. At least one arm is pivotally coupled with the tower structure. A flywheel and a cable and pulley system are associated with the at least one arm, wherein displacement of at least one cable of the cable and pulley system effects rotation of the flywheel. The strength training apparatus may include a selectively adjustable magnetic braking mechanism associated with a flywheel that is configured to apply a selected resistance to the rotation of the flywheel. A torque sensor may be associated with the flywheel and the measured torque during operation of the apparatus may be used to calculate the work expended in rotating the flywheel. In one embodiment, the calculated work may be expressed in units of watts.

Abstract: A level measurement system configured to measure minute changes in fluid level. The system integrates a linear variable differential transformer (LVDT) to provide highly accurate level measurement. Low friction materials and a timed vibrator are used to minimize fluid static friction effects on level measurement. A second LVDT can be utilized to compare the level of a fluid containment structure with level changes caused by environmental factors such as evaporation, tidal effects, wind, or the like. The system also includes a computing device to record and compare level changes over time. A housing connects the elements of the system.

Abstract: A vertical vat comprising a first shaft provided with at least one agitator panel, a second shaft provided with at least one agitator panel, wherein said first shaft and said second shaft are arranged to counter rotate.

Abstract: Incline mechanisms are provided for adjusting an incline of an inclinable portion of an exercise device. The incline mechanism may include one or more racks disposed on a frame, such as a generally upright support structure of a treadmill. One or more pinions may be movably connected to the inclinable portion of the exercise device, such as a treadbase of a treadmill, and may engage the one or more racks. An incline motor may rotate the pinions, which causes the pinions to ride up or down the racks. As the pinions rides up or down the racks or linear gear bars, the incline of the inclinable portion of the exercise device is increased or decreased. The pinions may rotate between various positions on the racks which correspond to various inclines and declines, including fully inclined, fully declined, and neutral positions.

Abstract: An abdominal exercise device includes a support structure, a track movable relative to the support structure, and a body support member movable relative to the support structure and track. A locking mechanism attaches to the track, and selectively secures the track at a fixed orientation relative to the support structure. In a first state, the locking mechanism restricts the track from rotating relative to the support structure. In a second state, the locking mechanism allows the track to rotate relative to the support structure. In using the exercise device, the user may obtain any of three motions. A first motion is provided by sliding the body support member along the track. A second motion is provided by rotating the track relative to the support structure. A third motion is a combined motion in which the body support slides along the track and the track rotates relative to the support structure.
