Patent number: 10059471Abstract: The present disclosure describes a method of deploying an extensible boom from a housing. Sheets supporting respective arrays of photovoltaic devices are deployed substantially simultaneously so that a first sheet is deployed in a first direction from the housing and a second sheet is deployed in an opposite direction from the housing. Angular momentum imparted by deploying the first sheet is canceled by angular momentum imparted by deploying the second sheet. The housing can be part of a space satellite, such that the first and second sheets are deployed without causing the satellite to move out of its orbit.Type: GrantFiled: June 29, 2017Date of Patent: August 28, 2018Assignee: SolAero Technologies Corp.Inventors: Kenneth Loyd Steele, Theodore Garry Stern

Patent number: 9079673Abstract: A retractable and re-deployable assembly is provided for collecting electromagnetic energy, for instance in outer space. The assembly has two layers: a first layer comprising a substrate and a second layer comprising an array of electromagnetic transducers. The second layer may further include a plurality of panels, each of which has a proximal edge and a distal edge opposite to the proximal edge. The panels also have a reflective surface and opposite the reflective surface a collector surface on which the array of electromagnetic transducers is disposed. The panels may be flexible and pre-formed to a cylindrical parabolic shape such that when this embodiment is in the deployed configuration, the edge of the panel curls away from the substrate layer because of the pre-formed parabolic shape, thus helping focus the energy on the transducers.Type: GrantFiled: March 13, 2015Date of Patent: July 14, 2015Assignee: Alliance SpaceSystems, LLCInventors: Kenneth Loyd Steele, Theodore Garry Stern

Patent number: 9004410Abstract: A retractable and re-deployable boom assembly is provided for collecting electromagnetic energy, for instance in outer space. The assembly may include a boom having a deployable length and a first layer comprising a flexible substrate formed in a lenticular shape that elastically deforms, and a second layer thereon comprising an array of electromagnetic transducers, which may be positioned on adjacent flexible parabolic reflectors. The assembly may be placed into at least two different configurations: a stowed configuration where the majority of the length is elastically deformed; and a deployed configuration where the majority of the length is not deformed, and where the lenticular shape of the boom provides it with rigidity. The assembly may also have a rotational drive mechanism.Type: GrantFiled: November 18, 2014Date of Patent: April 14, 2015Assignee: Alliance Spacesystems, LLCInventors: Kenneth Loyd Steele, Theodore Garry Stern

Patent number: 8439511Abstract: A mirror for terrestrial or aerospace application has a substrate, which is preferably of a laminate of a plurality of Graphite Fiber Reinforced Composite (GFRC) uni-directional fiber plies applied in a laminate with layers oriented to achieve appropriate stable properties. The substrate is cured to form the desired shape with a first surface and a second surface opposite the first surface. A front buffering layer is immediately adjacent to and contiguous with the substrate on the first surface. The front buffer layer is of a material that buffers the surface morphology of the first surface of the substrate. A front specularizing layer is immediately adjacent to and contiguous with the front buffer layer. The specularizing layer is of a material for providing a smooth, low scatter optical surface. The specularizing layer can use an integral aluminized surface or an added vacuum deposited optical thin film coating for enhanced optical properties and durability.Type: GrantFiled: December 22, 2010Date of Patent: May 14, 2013Assignee: Vanguard Space Technologies, Inc.Inventors: Theodore Garry Stern, Stephen Leonard Engelson Wyatt

Patent number: 6713670Abstract: Provided are methods of manufacturing an electrostatically clean solar array panel and the products resulting from the practice of these methods. The preferred method uses an array of solar cells, each with a coverglass where the method includes machining apertures into a flat, electrically conductive sheet so that each aperture is aligned with and undersized with respect to its matched coverglass sheet and thereby fashion a front side shield with apertures (FSA). The undersized portion about each aperture of the bottom side of the FSA shield is bonded to the topside portions nearest the edges of each aperture's matched coverglass. Edge clips are attached to the front side aperture shield edges with the edge clips electrically and mechanically connecting the tops of the coverglasses to the solar panel substrate. The FSA shield, edge clips and substrate edges are bonded so as to produce a conductively grounded electrostatically clean solar array panel.Type: GrantFiled: August 14, 2002Date of Patent: March 30, 2004Assignee: Composite Optics, IncorporatedInventors: Theodore Garry Stern, Duane Eric Krumweide
