Abstract:

An emergency position indicating radio beacon ("EPIRB") includes a watertight housing with an ON-OFF switch on the outside of the housing which does not require holes through the housing wall. A floatation collar on the housing maintains the EPIRB in an upright position in the water and provides a storage cavity for a lanyard. Conductive grids on the interior of the housing either shield the EPIRB electronics from antenna radiation and form the lower half of the antenna, or couple the antenna to the water which acts as a ground plane, depending on whether the EPIRB is floating in the water or is surrounded by air.

Abstract:

A rolling chair frame that includes a one-piece tubular frame, a platform, movable mounting apparatus, and preventing apparatus. The one-piece tubular frame is attachable to a movable object. The platform is sidewardly movably mounted to the one-piece tubular frame and is adapted to replaceably receive a chair. The movable mounting apparatus sidewardly movably mounts the platform to the one-piece tubular frame and maintains the platform level as the movable object moves. And, the preventing apparatus prevents removal of the platform from the one-piece tubular frame, so that the platform cannot be unintentionally removed from the one-piece tubular frame.
