Abstract: Systems, methods, and computer-readable media for providing tools to validate color contrast are provided. To do so, three discrete color check processes are performed to ensure a user is able to identify when an icon is at risk of being inaccessible by some users. A border score considers each pixel at the edge of an icon compared to the background in which it is placed. An area score considers each discrete pixel of an icon compared to the background in which it is placed. A grid score considers a subdivision of an icon compared to the background in which it is placed. Using each of these three independent process, a summative score is provided. The summative score categories the icon into a risk level. Depending on the risk level, the icon may need to be refined to ensure it becomes more accessible.

Abstract: A vibration attenuator for an aircraft has first and second coaxial spinners configured for rotation about a mast axis and relative to a rotor. Upper and lower weights of each spinner are spaced radially from the axis and positioned 180 degrees from each other about the axis. The weights of each spinner are spaced from each other a distance parallel to the mast axis, each weight rotating about the mast axis in a different plane. The spinners rotate together relative to the rotor at a selected angular rate and are selectively rotatable relative to each other between a minimum-moment configuration, in which the upper weight of each spinner is angularly aligned with the lower weight of the other spinner, and a maximum-moment configuration, in which the upper weights are angularly aligned and the lower weights are angularly aligned, producing a whirling moment about the mast axis as the spinners rotate.
