A chair is stabilized in two orthogonal axis, pitch and roll, can hold a person stable in relation to the horizon. This solution to motion sickness is effective because the fluid in the inner ear no longer moves in relationship to the vehicle motion upon which the person is located. Therefore a main cause of motion sickness is substantially reduced or eliminated. Additionally, the invention can be a table, a bed, or even an entire room that is isolated from the rolling, pitching and jolting imparted by the host vehicle. Additionally, some applications such as a chair and table, may be stabilized in a third orthogonal axis, azimuth.

A design and construction method reduces the amount of structural material (e.g., steel) required when applying the corrosion allowance to the design of floating offshore structures. The (hull) structural elements involved are typically flat or curved panels where at least one side is wet, e.g.; inside a ballast tank or exposed to seawater. The method minimizes the area to which the largest corrosion allowance is applied. One principle of this method is to have a maximum of one wet side for each hull watertight plating element. The stiffening of this hull structural element is applied to the dry side, i.e., the side that requires the lesser amount of corrosion allowance. Practice of the method typically results in a hull design wherein ballast tanks do not share a common structural element with either another ballast tank or the hull external shell.
