Patent number: 7582349Abstract: The present invention relates to a morphing cellular structure. The morphing cellular structure comprises a group of unit cells with each unit cell configured to have a cellular geometry. The group unit cells are formed of an active material, where the active material has both a first state and a second state. The active material is responsive to an actuation signal such that when the actuation signal is actuated, the active material is deformed from the first state to the second state, thereby changing the volume of each unit cell affected by the actuation of the actuation signal and morphing the cellular structure. Furthermore, both a passive material and at least one additional active material can be attached with the active material, allowing a user to selectively change the shape of the cellular structure.Type: GrantFiled: February 3, 2005Date of Patent: September 1, 2009Assignee: HRL Laboratories, LLCInventors: Guillermo A.

Patent number: 7562507Abstract: The present invention relates to vacuum insulated building panels. The insulating building panel of this invention uses suction pressure created by a vacuum as the sole means of attachments between two parallel steel (10) or glass (12) panel plates and a post frame (14). When vacuum is applied, the plates engage the post frame in an airtight manner and spheres (112) are used as spacers to maintain separation of the plates and they roll without resistance to accommodate any movement of one plate in relation to the other. These features of the building panel eliminate warping which is caused by expansion or contraction of weather exposed faces of the panel plates due to fluctuating outside temperatures and also eliminate stress upon support structures.Type: GrantFiled: April 1, 2005Date of Patent: July 21, 2009Inventor: Wallace E.

The flexible layer may be permanently deformed along the part surface or part surfaces that are in abutment against, but not adheringly bonded to the base layer, so that it substantially deviates from being in abutment against the base layer. Methods of producing a multilayer structure and a packaging laminate, as well as packaging containers produced from the packaging laminate are also disclosed.Type: GrantFiled: November 15, 2002Date of Patent: August 31, 2004Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Rolf Lasson, Karl-Håkan Sandell

Patent number: 6773785Abstract: A three dimensional air cushion having a sealed outer peripheral edge of a geometric shape. The projected area of the hollow interior sealed by the outer peripheral edge is smaller than the upper surface area of the air cushion. Air chambers are provided in an upper surface and a lower surface of the cushion, giving excellent buffering function. Two opposite sides of the cushion have a level higher than an intermediate portion to force an object it protects, or a shock source, to move to the center, with the shock energy converted into side support energy, thus obtaining great stability.Type: GrantFiled: July 9, 2001Date of Patent: August 10, 2004Inventor: Ing-Jing Huang

Publication number: 20040105953Abstract: The invention relates to an insulating member and a method of producing said member. Such an insulating member consists of two sheet metal walls 1, 2, a sealing profile 3 connecting the walls 1, 2 hermetically at the edge, and dimensionally stable sealing material 4, more particularly an open-pored cellular material, which is accommodated in the evacuated cavity formed by the walls 1, 2 and the sealing profile 3 hermetically connected thereto. The sealing material 4 is dimensionally stable and supports the walls 1, 2. To improve the insulating effect of the insulating member in the edge zone also, the hermetic connection of the sealing profile 3 to the walls 1, 2 takes the form of a heat sealing, and the sealing profile itself does not consist of sheet metal, but of a material having a lower thermal conductivity, low vapour permeability and satisfactory hot sealing properties.Type: ApplicationFiled: July 10, 2003Publication date: June 3, 2004Inventor: Ekkehard Nowara

Publication number: 20040058119Abstract: A core panel or box of rigid plastics microporous foam is provided with parallel spaced passages or thin grooves and is placed within an envelope or bag of flexible multi-layer barrier film impervious to the passage of gas. The bag includes an integral evacuation tubular portion which is releasably coupled to an evacuation nozzle connected by a manifold with solenoid valves to a vacuum pump. After air is substantially evacuated from the foam core and the bag to collapse the bag against the foam core and into the grooves, a vacuum sensor operates a computer which controls the valves for checking the vacuum level within the bag and for optionally admitting an additive gas. Closely spaced grooves within opposite sides of the foam panel provide for bending the evacuated panel, and a thin layer of foam is applied to the outer surface of the vacuum insulated panel to provide a protective outer surface.Type: ApplicationFiled: September 18, 2003Publication date: March 25, 2004Applicant: Energy Storage Technologies, Inc.Inventor: Nicholas Wynne

Publication number: 20040018335Abstract: The invention provides an edge insulation piece (1) comprising a thin sheet of material (2) which is manipulated by bending, rolling or other forming to effect a long conductive path within a small cross-sectional area. In a preferred embodiment, a thin layer of insulation material (3) is interleaved between two layers of the thin sheet of material (2), which is folded around the insulation layer (3) during forming of the edge piece (1). A further layer of insulation material (4) may be rolled within the edge piece (1) as it is. This interleaving of thin layers of insulation material (3, 4) prevents the surfaces of the thin sheet of material (2) from touching each other and also insulates the material (2) from the top and bottom panels (5, 6) of a vacuum insulation panel (7) when the edge piece (1) is inserted around the edge of the panel (7). The edge piece (1) may be further coated over part or all of its length with a low emissivity material (13) to minimise radiative losses.Type: ApplicationFiled: August 14, 2003Publication date: January 29, 2004Inventor: Frederick G. Best

Patent number: 6645598Abstract: Heat insulation blanket (10) includes a layer of inner cells (16) containing a phase change material, and opposed outer cells (18 and 19) containing dead air or other undisturbed gas. When placed in an attic or other insulated area, the phase change material changes phase when the outside atmospheric temperature passes the phase change temperature, resulting in a delay in the transfer of heat between the interior space and the atmosphere because of the heat required for or given up by the PCM during its change of phase. The outer plies of sheet material that form the superposed cells of the cell blanket are formed with a coating of heat reflective material that faces the interior of the cell blanket, whereby the reflective surfaces are protected against deterioration and retain their capacity to reflect radiant heat.Type: GrantFiled: March 21, 2002Date of Patent: November 11, 2003Inventor: Robert J. Alderman

Patent number: 6630220Abstract: A method is disclosed for producing an air-holding vehicle restraint system, wherein a textile fabric is coated on at least one side with a thermoplastic polymeric material and folded along its lengthwise direction to form a closed bottom end and two open upper ends, with the coated side of the fabric facing inwardly. The method also comprises folding a portion of each of the upper open ends of the textile fabric so that they turn outwardly to form a coated platform, and laying a sealing tape upon the coated platform. The sealing tape is then secured to the coated platform and sealed to the coated platform. The method further comprises cutting the coated textile fabric along predetermined side edges to form an air-holding vehicle restraint system of desired shape, and sealing the cut side edges of the coated textile fabric.Type: GrantFiled: May 17, 2000Date of Patent: October 7, 2003Assignee: Bradford Industries, Inc.Inventor: Manuel J.
