Patent number: 8902322Abstract: An imaging system comprises four image sensors each pointing outwardly from the vertices of a notional tetrahedron with the optical axes of the image sensors substantially collinear with respective medians of the notional tetrahedron, with the focal plane array of each image sensor positioned between the lens system of its respective image sensor and the centroid of the notional tetrahedron. The imaging system and can be used to obtain image data for generating a spherical image of the space surrounding the imaging system. A method for generating a spherical image from this image data assigns spherical coordinates to the pixels in the images according to a cylindrical projection that is individually aligned with the image plane of each image, and blends overlapping pixels and fills blank pixel spaces. The method can be applied to image data representing outward views from the vertices or centroids of faces of any Platonic solid.Type: GrantFiled: November 9, 2012Date of Patent: December 2, 2014Assignee: Bubl Technology Inc.Inventors: Sean Geoffrey Ramsay, Daniel Chantal Mills, Dylan Stephen Horvath, Scott Andrew Robinson Bodaly

Patent number: 4490349Abstract: Method and apparatus for deriving hydrogen from superheated steam. Superheated steam is passed into chamber between opposing chamber walls. One of chamber walls is formed of a reactant such as iron which reacts exothermally with the superheated steam to liberate free hydrogen and to produce an oxidized compound such as ferric oxide. The other chamber wall is formed as a thin diffusion membrane permeable to hydrogen but relatively impermeable to steam and oxygen and hydrogen is extracted from the chamber by diffusion therethrough. The membrane is preferably made of palladium or a palladium-silver alloy to further decompose the superheated steam and enhance extraction of hydrogen. The reactant wall is heated at its side remote from the chamber in a reducing atmosphere to cause dissociation of the oxidized compound and removal of oxygen so as continuously to regenerate the reactant.Type: GrantFiled: August 17, 1981Date of Patent: December 25, 1984Assignee: Beeston Company LimitedInventor: Stephen Horvath

Patent number: 4454850Abstract: Process and apparatus for liberation of energy by controlled nuclear fusion reaction involving isotopes of hydrogen gas. Highly ionized hydrogen gas containing a higher proportion of deuterium than in naturally occurring hydrogen is pressurized, together with an oxidizing gas within combustion chamber of reciprocating piston and cylinder engine. An electrical discharge within the combustion chamber causes generation of heat by atomic dissociation and exothermal recombination of hydrogen atoms and electrical excitation of ionized gas. Ionized deuterium in the hydrogen gas undergoes a nuclear fusion reaction with consequent liberation of heat energy and remaining hydrogen gas burns in the oxidizing gas to provide control on fusion reaction. Apparatus for producing ionized hydrogen gas in appropriate form by treatment of normal industrial hydrogen gas is disclosed, and also gas mixing apparatus for mixing the ionized hydrogen with atmospheric air as the oxidizing gas.Type: GrantFiled: November 4, 1981Date of Patent: June 19, 1984Assignee: Beeston Company LimitedInventor: Stephen Horvath

Patent number: RE30263Abstract: A catch mechanism for installation in a door frame to cooperate with a door lock on a fire door. The mechanism includes a catch member pivotable between an operative position in which to serve as a door catch and an inoperative position to enable release of the door no matter what the condition of the door lock. The mechanism includes a heat responsive locking device which locks the catch member in its catch position in the event of a fire generating high temperatures. The locking device may comprise a biased locking plunger mounted in a cavity within the catch member and normally held in a retracted position by a heat fusible metal plug but extendible on melting of the plug to engage the catch body and so lock the catch member.Type: GrantFiled: July 21, 1978Date of Patent: April 29, 1980Assignee: Access Controls System Pty. Ltd.Inventor: Stephen Horvath
