Patent number: 7851017Abstract: A method for forming a duct access region through one side of a previously installed air duct, wherein the air duct has an air flow with an air flow direction by inserting an aerosol injector into a previously installed air duct through the access region. The aerosol injector includes a liquid tube having a liquid tube orifice for ejecting a liquid to be atomized; and a propellant cap. The method is accomplished by aligning the aerosol injector with the direction of air flow in the duct; activating an air flow within the duct; and spraying a sealant through the aerosol injector to seal the duct in the direction of the air flow.Type: GrantFiled: August 29, 2006Date of Patent: December 14, 2010Assignee: The Regents of the University of CaliforniaInventors: Duo Wang, Mark P.

Publication number: 20080019604Abstract: The invention provides a method for dynamically processing an image. In an exemplary embodiment, the image comprises a plurality of pixels. First, a value of a target pixel of the pixels is subtracted from values of surrounding pixels of the target pixel to obtain a plurality of difference values. A plurality of absolute values of the difference values is then calculated. The absolute values are then summed to obtain an accumulation value. The accumulation value is then compared with N reference values to select a target interval corresponding to the accumulation value. A filter coefficient set corresponding to the target interval is then determined. Finally, the target pixel is filtered according to the filter coefficient set.Type: ApplicationFiled: June 8, 2007Publication date: January 24, 2008Applicant: VIA TECHNOLOGIES, INC.Inventors: Zhen-Yong Gao, Wan-Duo Wang, Jiunn-Shyang Wang, Seng-Che Tsao

Publication number: 20070269988Abstract: The present invention relates to a method for forming a contact opening. First, a substrate having at least a dielectric layer formed thereon is provided. Then, a photoresist layer having a first opening is formed on the dielectric layer. A plasma etching operation is performed to form a second opening in the dielectric layer, and the first opening is located above the second opening. The bottom part of the first opening has a diameter smaller than that of the top part of the second opening. Thereafter, the photoresist layer is removed from the dielectric layer. Accordingly, at least a portion of the exposed contact opening will not be oxidized to prevent an increase in the resistance between the conductive pattern and the conductive layer that fills in the contact opening.Type: ApplicationFiled: May 18, 2006Publication date: November 22, 2007Inventors: Ying-Chou Chi, Rong-Duo Wang, Ying-Tsung Tu, Chao-Huan Hsu

Patent number: 7207228Abstract: A method and apparatus for measuring fluid flow in a duct is disclosed. The invention uses a novel high velocity tracer injector system, an optional insertable folding mixing fan for homogenizing the tracer within the duct bulk fluid flow, and a perforated hose sampling system. A preferred embodiment uses CO2 as a tracer gas for measuring air flow in commercial and/or residential ducts. In extant commercial buildings, ducts not readily accessible by hanging ceilings may be drilled with readily plugged small diameter holes to allow for injection, optional mixing where desired using a novel insertable foldable mixing fan, and sampling hose.Type: GrantFiled: August 11, 2004Date of Patent: April 24, 2007Assignee: The Regents of the University of CaliforniaInventor: Duo Wang

Publication number: 20070001030Abstract: A clog-resistant injector spray nozzle allows relatively unobtrusive insertion through a small access aperture into existing ductwork in occupied buildings for atomized particulate sealing of a ductwork. The spray nozzle comprises an easily cleaned and easily replaced straight liquid tube whose liquid contents are principally propelled by a heated propellant gas, such as heated air. Heat transfer is minimized from the heated propellant gas to the liquid tube until they both exit the injector, thereby greatly reducing the likelihood of nozzle clogging. A method of duct sealing using particles driven by heated propellant gas is described, whereby duct-sealing operations become both faster, and commercially practicable in inhabited commercial and residential buildings.Type: ApplicationFiled: August 29, 2006Publication date: January 4, 2007Inventors: Duo Wang, Mark Modera
