Publication number: 20240103301Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: Victoria C.

Patent number: 6830130Abstract: A vertically placed ladder is positioned approximately 3 to 5 feet from a building and has attached thereto a horizontal beam which is also attached to a vertical stand placed on the roof of the one-story building. The horizontal beam has a U-shaped interior channel within which there is located a roller assembly designed to roll along tracks within the interior of the U-shaped channel, either flat or semi-circular, along the length of the horizontal beam and has attached thereto a winch line which is connectable to a load to be lifted from the earth's surface in a vertical line. The roller assembly also allows the load to be moved along a straight horizontal line until the load is above the surface upon which the load is to be deposited, and then the winch line allows the load to be lowered to the surface upon which the load is to be deposited.Type: GrantFiled: June 18, 2002Date of Patent: December 14, 2004Inventors: Wallace W.
