Abstract: Removable and re-attachable grips design to allow simple, fast changing of grips on shaft. The present disclosure relates in general to a re-changeable or interchangeable grip particularly suited for golf whose attachment requires three basic securing movements. In the first movement, heel components of the grip are first positioned onto the shaft, by either rotational torque or downward pressure, which result in securing the upper, proximal portion of the gripping sleeve onto the shaft. In the second movement, once the grip is situated and secured into place on the shaft, the grip is centered on the shaft by fastening toe components at the lower, distal portion of the grip sleeve onto the shaft.

Abstract: Systems and methods for obtaining and displaying a collimated X-ray image are described. The methods can include providing an X-ray device having an X-ray source, a square or rectangular X-ray detector, and a collimator. The collimator can be sized and shaped to collimate an X-ray beam from the X-ray source that exposes a receptor region on the detector. The collimator can allow the X-ray image received by the X-ray detector to have any suitable shape that allows a relatively large view of the image to be displayed and rotated on the display device without changing the shape or size of the image as it rotated. In some instances, the collimator provides the image with superellipse shapes or cornerless shapes having four substantially straight edges with a 90 degree corner missing between at least two edges that run substantially perpendicular to each other. Other embodiments are described.
