Abstract: A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

Abstract: Methods, systems, and computer program products for generating revised videos. The method includes, for example, receiving, by one or more processor, first video data of an environment having at least one projection on a screen from a first point of view, and generating, by the one or more processor, revised video data of the environment having the at least one projection on the screen from the first point of view based on the first video data, the revised video data comprising a plurality of frames with the at least one projection on the screen disposed in the first area relative to the environment in a plurality of frames being revised based on data for projecting the at least one projection on the screen in the first video data.
