Abstract: The collapsible baseball equipment hanger apparatus is selectively folded for transport and unfolded for use in removably attaching to a fence or other object via the hooks provided at the top edge of the rear panel. The left side panel, right side panel, and rear panel pivot or fold inwardly to lie atop the base and each other, progressively. The collapsed apparatus thereby provides a relatively small size for transport. The base, with side panels folded out and up, is of sufficient size to hold a helmet therebetween. The drink holder can optionally include insulation for aiding in maintaining drink temperature, and the forwardly positioned container provides for best visual and manual access. The shamrock-shaped bat slot provides for individual access of up to three bats in a very compact area and at the front of the base for easiest access. Accessory hooks provide for removably holding various items.

Abstract: The present invention relates to an improvement of a total internal reflection lens whereby a tilted symmetry axis leads to a net deflection of the output beam away from the surface normal of the exit surface. Linear TIR lenses have a net deflection transverse to their focal strip. Circular TIR lens profiles going beyond 90° are tilted to bring the rim level with the source, the deflected rays exiting the lens to form an off-axis beam.
