  • Publication number: 20190346997
    Abstract: A system and method for displaying a non-biasing VAS that automatically adjusts to different screen aspect ratios resolutions of a computing device, while preserving the reliability of the VAS. The system and method can calculate a number of pixels available on a screen display to display a VAS. Further, the system and method can generate a VAS comprising equally sized intervals of distance to fit the available screen display. In addition, the system and method can include an anchor line at each end of the VAS that indicates an upper and lower value of a range of values measured by the VAS. The system and method can also include a unit cursor on the VAS that allows a subject to indicate, by pixel, interval or target area, a position on the VAS.

  • Patent number: 4888836
    Abstract: Furniture which resides in one of a levitated position and a sunk position is disclosed. The furniture includes a bladder which is shaped to remain stable when placed on a floor and which is shaped to support a body. The bladder contains a lighter-than-air gaseous substance, such as helium, confined therein. The gaseous substance operates in conjunction with the bladder to define the furniture shape. The bladder is dimensioned to contain a sufficient quantity of the gaseous substance so that buoyancy in the atmosphere causes it to rise to a ceiling of a room when the furniture is out of use. The furniture additionally includes a tether attached to a bottom surface thereof. The furniture is moved from a levitated, out-of-use, position to a sunk, in-use, position by grasping the tether and pulling the furniture downward from the ceiling. The furniture may then be maintained in the sunk position, wherein it rests on a floor of the room, by using the furniture in a conventional manner to support a body.
