Abstract: A golf ball has a first hemisphere and a second hemisphere and a plurality of dimples arranged in a pattern divided into dimple segments separated by n longitudinal lines. Within each hemisphere, the plurality of dimples consists of shared dimples that are intersected by the longitudinal lines and segment dimples that are each wholly within one of the n number of dimple segments. The arrangement of the shared dimples on each of the longitudinal lines is identical. The n number of dimple segments comprise at least two segments, S1 and S2, in each hemisphere that have a different longitudinal angle from each other. The S1 segment has a first value for a segment parameter and the S2 segment has a second value for the segment parameter. The first value is different than the second value.

Abstract: A motion platform comprises a base portion and an occupant carrier portion. The occupant carrier portion is linearly moveable along, and rotationally moveable about, first, second, and third orthogonal axes. The base portion comprises first, second, and third control pillars each extend along the third axis with a predetermined height. The control pillars are linearly moveable in a plane defined by the first and second axes and are mechanically constrained to move only in that plane. The occupant carrier portion comprises first, second, and third guide portions that are pivotally connected to the first, second, and third control pillars respectively by a respective coupling member. Each of the guide portions is angled with respect to the plane defined by the first and second axes such that they are not parallel to the plane. The guide portions are also angled with respect to each other such that they are not parallel with each other.

Abstract: The present teachings generally include flexible pickleball paddles and/or frames thereof. In an aspect, a frame of a paddle includes a region adjacent to a throat portion of the paddle that is thinner than other regions of the frame, e.g., thicker regions disposed along its sides, top, and/or handle. The lack of material in this portion of the frame—e.g., disposed directly above the handle—may provide advantageous flexing of the paddle during play (e.g., how fast the paddle can return to the original shape after being flexed), improving power characteristics, control, feel, responsiveness, and/or the like. Moreover, a gap formed by the lack of material in this portion of the frame can provide a region for enhanced weight control (e.g., by filling the gap with a weighted material), and/or for enhanced sound or vibration control (e.g., by filling the gap with a sound dampening and/or vibration dampening material).
