Publication number: 20090253369Abstract: The emittance value is a measure of an amount of energy expelled from a given surface area relative to a black-body reference. Depending on the specific coating a change in the emittance value is actively or passively effected. There are known active variable emittance thermal control coatings. However, such coatings are actually panels housing a mixture of both high and low emissivity materials that are electrically manipulated to control the emittance value of the panel. These “coatings” are classified as either electrochromic or electrophorectic. Both electrochromic and electrophorectic coatings require an applied voltage to cause a change in the emittance value of the coating. By contrast, aspects of the present invention do not include active variable emittance thermal control coatings. Aspects of the present invention do include passive variable emittance thermal control coatings and materials.Type: ApplicationFiled: September 8, 2006Publication date: October 8, 2009Applicant: MPB COMMUNICATIONS INC.Inventors: Roman V.

Publication number: 20080113160Abstract: One or more cavities are formed in the bonding surfaces of one, all, or some of the elements to be bonded. These cavities serve as receptacles for the bonding material and are where the bonds are localized. The cavities are of sufficient size and shape so that their volume is greater than the volume of bonding material forming the bond. This ensures that when the elements are brought into contact with one another to mate, the bonding material, which can flow prior to solidifying into a bond, will flow into the cavities and will not impede the separation of the parts. This allows the parts to be mated with nominally zero separation. Once solidified, the bonding material forms a localized bond inside each cavity. Different cavity shapes, such as, rectangular, circular, or any other shape that can be injected or filled with adhesive material may be used.Type: ApplicationFiled: November 14, 2006Publication date: May 15, 2008Applicant: Glimmerglass Networks, Inc.Inventors: Andres Fernandez, Bryan P.

Publication number: 20030012930Abstract: A single-electron transistor includes a projecting feature, such as a pyramid, that projects from a face of a substrate. A first electrode is provided on the substrate face that extends onto the projecting feature. A second electrode is provided on the substrate face that extends onto the projecting feature and that is spaced apart from the first electrode. At least one nanoparticle is provided on the projecting feature between the first and second electrodes. Accordingly, the geometric configuration of the projecting feature can define the spacing between the first and second electrodes.Type: ApplicationFiled: July 13, 2001Publication date: January 16, 2003Inventor: Louis C. Brousseau

Patent number: 6471881Abstract: A method is disclosed for providing a TBC system including grooves or other features between the bond coat/substrate and the ceramic thermally insulating layer. The features are initially provided by selectively removing material to define the features, for example by laser. Any disturbed surface layer, e.g., re-cast material in the case of a laser or plastically worked material in the case of machining, is then chemically removed, leaving the remaining material with a microstructure of a more uniform geometry, and free of disturbed material. The ceramic layer is then applied. TBC systems using the method show improved durability, with lives up to 4× longer than prior TBC systems.Type: GrantFiled: November 23, 1999Date of Patent: October 29, 2002Assignee: United Technologies CorporationInventors: Yan Chai, Gary M. Lomasney, Keith Douglas Sheffler

Publication number: 20020127373Abstract: The present invention is a process and its product by embossing or processing the transparent soft or solid thermoplastic polyvinyl chloride(PVC) sheet, the thermoplastic polyethylene(PE) film sheet, the ethylenevinyl acetate copolymer(EVA) film sheet, and the PEVA (the mixture) film sheet; and more particularly a product by utilizing said thermoplastic material plastic sheet printed by lithographic or gravure printing; whereon a pattern arranged by a computer is printed. The plastic sheet is further embossed by a embossing machine on both front and rear sides to produce a coordinated indension so as to produce a product with a stereo flash effect.Type: ApplicationFiled: March 8, 2001Publication date: September 12, 2002Inventor: Tai-Hsiung Lin

Publication number: 20020106488Abstract: A foam rubber sheet comprises a substrate made from rubber material and two cloth layers respectively bonded to two sides of the substrate. Each cloth layer has an outer surface comprising a plurality of recessed portions and a plurality of protruded portions. The foam rubber sheet is made from a foam rubber sheet raw material having the substrate and two second cloth layers bonded to both sides of the substrate. A pair of embossing rolls is provided for drawing the foam rubber sheet raw material to pass through the embossing rolls. Each embossing roll includes an outer surface with a pattern, the pattern being configured to form the recessed portions and the protruded portions on each second layer cloth when the foam rubber sheet raw material is passing through the embossing rolls, thereby forming the foam rubber sheet with the cloth layers having the recessed portions and the protruded portions.Type: ApplicationFiled: February 7, 2001Publication date: August 8, 2002Inventor: Chien Chung Hu

Patent number: 6383608Abstract: A foam body structure formed of plastic foam with one or more flame retardant reception cavities formed in the main body either simultaneously with an initial foam body formation process such as expandable plastic bead molding or subsequent to the foam body formation such as by melting, drilling or cutting. A solid flame retardant such as one in granular form is preferably supplied in sufficient quantity as to entirely fill the volume defined by the reception cavities. A covering or coating is provided over the flame retardant material to fix the material within the cavities. The volume and distribution of the reception cavities and the amount of the chosen flame retardant received in the cavities is sufficient to provide an essentially common flame retardation quality or characteristic over the entire volume of foam body (or at least the volume that could be exposed to a flame in its intended use).Type: GrantFiled: September 16, 1998Date of Patent: May 7, 2002Inventors: William Burkett, Marvin Carnahan

Publication number: 20020045030Abstract: This invention describes methods of synthesis and applications of planarized photonic crystals. Provided are simple, quick, reproducible and inexpensive methods that combine self-assembly and lithography to achieve the first examples of vectorial control of thickness, structure, area, topology, orientation and registry of colloidal crystals that have been patterned in substrates for use in lab-on-chip and photonic chip technologies. 1-, 2 and 3-D colloidal crystals patterned either on or within substrates can be used for templating inverted colloidal crystal replica patterns made of materials like silicon as well as building micron scale structural defects in such colloidal crystals.Type: ApplicationFiled: October 16, 2001Publication date: April 18, 2002Inventors: Geoffrey Alan Ozin, San Ming Yang, Hernan Miguez
