Appl. No.:

11/256304

Inventors:

Steven Crow - Denver CO, US

International Classification:

G06F 19/00

US Classification:

702 23, 702138, 738651

Abstract:

The invention disclosed herein employs an algorithm, the Gas Formation Model (“GFM”), to calculate the formation of free gas in a human body. The GFM is based on a novel theory of the formation of free gas relative to the physiology of the human cardiovascular system. Additionally, the GFM utilizes a novel means for the solution of integro-differential equations, the type of equations that derive from the introduction of physiological parameters. GFM-based dive computers utilize novel inputs, including a measure of exercise at depth to reflect the state of an individual's cardiovascular system. GFM-based dive computers also produce novel outputs, including the actual volume of free gas present in a diver's cardiovascular system. The GFM is implemented as a practical computational tool by means of a incorporating the algorithm into a dive computer.

Abstract:

A single-crystal solid oxide material, rather than a polycrystalline ceramic, is used for electrolytic and fuel-cell applications. For the electrolytic production of oxygen from carbon dioxide, a yttria-stabilized zirconia crystal is coated with platinum electrodes and encased in a platinum structure to provide a thermally stable electrolytic cell. A multilayered device is constructed by stacking crystals and spacers in alternating arrangement and by plumbing the active surfaces of the crystals in parallel through perforations drilled directly in the solid-oxide crystals, so that manifolding and sealing problems are minimized.

Abstract:

A roadable airplane consists of a single-seat three-wheeled vehicle with wing panels hung longitudinally on the sides of the chassis for road use and attached transversely to a spar box for flight. A power train is used that enables the simultaneous powering of two rear wheels and an overhead pusher propeller for transition from road to air travel. A transaxle for a four-wheel automotive vehicle was found to be advantageously suitable for this purpose. Multiple gears and differential outputs drive the wheels, providing a normal automotive performance on the road. Multiple gears are also available to drive the propeller, thereby providing the function of variable-pitch performance using a fixed-pitch propeller. The vehicle includes a standard automotive gear shift and pedal controls for clutch, brake and accelerator operation; a novel joystick assembly is used to steer the front wheel and to control wing flaps, an elevator and a rudder.
