TL;DR: It was concluded that the kayak paddle power meter tested is a valid means of recording work rate and stroke kinetics during kayaking in the field.
Abstract: The ability to quantify power within the sport of slalom kayaking would provide coaches and athletes objective data to monitor performance. This study determined the validity of a kayak paddle power meter and subsequent relationship between work rate and stroke kinetics. One participant completed multiple trials of a flat-water, straight-line sprint and a sequence of slalom gates at numerous intensities to attain the velocity:power relationship. Laboratory results identified the kayak paddles’ strain gauges were valid and reliable, and field tests presented a cubic relationship for power as a function of velocity in the straight-line sprint (R2=0.982) and the slalom-specific test (R2=0.993). Further analysis of stroke kinetics identified velocity of hand movement at individual peak force capability to be critical in the highest work rates achieved for both slalom and flat-water sprinting. It was concluded that the kayak paddle power meter tested is a valid means of recording work rate and stroke kinetics during kayaking in the field.

TL;DR: In this paper, a two-axis tracking mechanism for a concentrated photovoltaic system is described, where two or more paddle structures containing multiple CPV modules are installed onto each tilt axle on the common roll axle as part of the tracking mechanism's solar array.
Abstract: Methods and apparatus are described for a two axis tracking mechanism for a concentrated photovoltaic system. Two or more paddle structures containing multiple CPV modules are installed onto each tilt axle on the common roll axle as part of the two-axis tracking mechanism's solar array. The two or more paddle structures couple across the common roll axle on that tilt axle. The common roll axle and each paddle assembly are manufactured in simple modular sections that assemble easily in the field while maintaining the alignment of the tracker assembly.

TL;DR: A swimming aid includes a paddle with two blades for alternating arm strokes and a vertical blade attached to both feet for side-to-side leg motion in cooperation with the arm strokes as discussed by the authors.
Abstract: A swimming aid includes a paddle with two blades for alternating arm strokes and a vertical blade attached to both feet for side to side leg motion in cooperation with the arm strokes. The two paddle blades are at opposite ends of a hand held shaft. Each blade has a rigid leading edge and a flexible following portion. When pushed forward, the blade lies in a plane for minimal hydrodynamic resistance. When pulled backward on a power stroke, the following portion bends out of the plane, creating increased hydrodynamic resistance for enhanced forward propulsion. This pulling action causes the legs to move laterally, alternating from side to side as the arm strokes alternate. A vertical blade has a narrow anterior portion with foot pockets for both feet side by side. The blade is widest at its trailing edge which may be forked and acts like a fish tail fin forcing the body forward. The propulsion is provided by the torso muscles moving the legs side to side not by leg muscles kicking as in swim fins.

TL;DR: In this paper, a package for adhesives having first and second parts including a card slideable within a box, premeasured adhesive portions in compartments shaped to conform to a dispensing and mixing paddle, and a mixing vessel dimensioned to receive the compartments therein is described.
Abstract: A package for adhesives having first and second parts including a card slideable within a box, premeasured adhesive portions in compartments shaped to conform to a dispensing and mixing paddle, and a mixing vessel dimensioned to receive the compartments therein The card may be capable of interlocking engagement with the box to prevent card removal The conformity of the compartment shape to the dispensing and mixing paddle allows substantially the entire contents of the compartment to be removed with one pass of the paddle
