Patent number: 7371329Abstract: Methods for filtering particles from a fluid are disclosed, wherein an array of microstructures defining respective microchannels having respective minimum widths are used to separate the fluid from particles to be filtered. The fluid flows through the minimum widths into the microchannels defined between adjacent microstructures. The particles to be filtered are prevented from passing through the respective minimum widths, resulting in filtration of those particles from the fluid. The microchannels can be provided with gradient characteristics to separate particles in the fluid according to size.Type: GrantFiled: March 6, 2006Date of Patent: May 13, 2008Assignee: OC Oerlikon Balzers AGInventors: Johannes Edlinger, Claus Heine-Kempkins, Othmar Zuger

Publication number: 20080074738Abstract: A solar control member for determining solar control for a window includes an optically massive layer between a gray metal layer and a titanium nitride layer. The optically massive layer has sufficient thickness to retard or prevent constructive and destructive interference of reflected light. The optically massive layer may be an adhesive, but also may be one or more polymeric substrates. The gray metal layer is preferably nickel chromium, but other gray metal materials provide superior results as compared to the prior art. Also in the preferred embodiment, the titanium nitride layer is closer to the window (e.g., glass) than the gray metal layer.Type: ApplicationFiled: September 21, 2006Publication date: March 27, 2008Inventors: Yeo Boon Khee, Yisheng Dai, Sicco W.T.

Patent number: 7347592Abstract: A reflector for use in a projection system comprises an anodized metal substrate having a metal oxide layer. The metal oxide layer has a plurality of pores. A light absorbing pigment is deposited into each of the pores such that the light absorbing pigment and the metal oxide layer form a light absorbing layer on the metal substrate.Type: GrantFiled: July 14, 2005Date of Patent: March 25, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventors: Peter Mardilovich, Kurt Ulmer

Patent number: 7342715Abstract: A multilayer film reflector for X-rays has alternately stacked layers formed on a substrate and comprising a layer (high refractive index layer) comprising a material having a large difference between a refractive index to soft X-ray and a refractive index in vacuum, and a layer (low refractive index layer) comprising a material having a small difference between a refractive index to soft X-ray and a refractive index in vacuum, wherein at least one intermediate layer having a crystalline structure is provided between the low refractive index layer and the high refractive index layer. Thereby, the crystallization of the low refractive index layer is promoted, the refractive index of the low refractive index layer is lowered, so that the reflectance of the multilayer film reflector is improved.Type: GrantFiled: March 24, 2005Date of Patent: March 11, 2008Assignee: Canon Kabushiki KaishaInventors: Kyoko Imai, Kenji Ando, Hidehiro Kanazawa, Koji Teranishi, Takayuki Miura, Kazue Takata

Publication number: 20080055717Abstract: In accordance with the invention, a filter is fabricated by a modified form of the process disclosed in U.S. Pat. No. 7,068,430. In particular, the method is modified to take into account the effect of absorption by filter material. The method is exemplified by the fabricating of an ultraviolet light transmission filter for transmitting a band within the range 230-320 nanometers. The resulting filter comprises plurality of hard-coating, thin-film layers of alternating high and low index of refraction. The improved filter provides high transmission, sharp edge slopes, and deep and extended out-of-band blocking. As compared with currently available filters, the filter provides transmission up to three or more times greater, edge slopes up to four times sharper, and deep extended out-of-band blocking extending further, even through the visible range.Type: ApplicationFiled: August 31, 2007Publication date: March 6, 2008Inventors: Atul Pradhan, Jay Anzellotti, Joseph T.
