Patent number: 12339813Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for providing an embedded web view of a folder in a content management system on a web page. For example, a user can request from a content management system code for embedding a web view of a content item or group of content items (e.g., folder) into a web page. After the code is embedded into the webpage, the web page can present a web view of the content item or group of content items that is dynamically updated when the content item or group of content items is updated. Thus, the user is relieved of the burden of updating the web page with new links to reflect changes in content items stored in the online content management system.Type: GrantFiled: March 29, 2024Date of Patent: June 24, 2025Assignee: Dropbox, Inc.Inventors: Roger Tu, Aisha Ferrazares, Jennifer Lee, Sang Tian

Patent number: 6924913Abstract: A multiple-resolution scanning device introduces an image information obtained by scanning a document into a light folding device and the image information is reflected in the light folding device. The image information comes out from the light folding device and received and reflected by a final reflection mirror unit, and passes through a lens unit and then focused on an optical sensor. By adjusting the light folding device or the final reflection mirror unit, or by adjusting the light source and the light folding device to change the position or angle thereof to achieve the purpose of changing the path of light of the image information and obtain the scanned results having different resolutions.Type: GrantFiled: March 6, 2002Date of Patent: August 2, 2005Assignee: Avision Inc.Inventors: Thomas Sheng, Chi Yao Chen, Hyman Shiao, Yueh Shing Lee, Roger Tu, Yung Chuan Wu

Publication number: 20050119636Abstract: The invention discloses a trabecular stent and methods for treating glaucoma. The stent may incorporate an intraocular pressure sensor comprising a compressible element that is implanted inside an anterior chamber of an eye, wherein at least one external dimension of the element correlates with intraocular pressure. In some embodiments, the sensor may be coupled to the stent. Also disclosed are methods of delivery of the stent and the sensor to the eye.Type: ApplicationFiled: September 24, 2004Publication date: June 2, 2005Inventors: David Haffner, Roger Tu, Gharib Morteza

Patent number: 5769780Abstract: Variably compliant natural tissue valve leaflets and vascular bioprosthetics incorporating variably compliant leaflets are provided along with methods for their manufacture. The variably compliant leaflets are fixed with the leaflet base section under greater pressure than the leaflet tip section rendering them relatively stiff along the leaflet base section and more flexible at the leaflet tip section. The radially variable flexing characteristics of the valve leaflets promote even distribution of mechanical stress on the valve assembly during the cardiac cycle leading to improved hemodynamic performance while retarding the calcification of the leaflet tissue.Type: GrantFiled: October 9, 1997Date of Patent: June 23, 1998Assignee: Baxter International Inc.Inventors: Cary Hata, Roger Tu, Hsing-Wen Sung, Shih-Hwa Shen

Patent number: 5376110Abstract: Preparing chemically cross-linked collagenous biological graft material by preparation processes which include the step of altering the locations and/or orientations of chemical cross-linkages formed during the collagen cross-linking process. Embodiments of the method include various processes whereby physical force, stress or movement is applied to alter the relative positioning of the collagen fibers within the graft materials during at least the initial period of exposure to the collagen cross-linking reagent.Type: GrantFiled: June 9, 1993Date of Patent: December 27, 1994Assignee: Baxter International Inc.Inventors: Roger Tu, Edwin Wang, Chris Kuo, Cary Hata

Patent number: 5061276Abstract: A vascular graft having a composite structure prepared by wrapping about the external surface of a tube having one or more layers of polytetrafluoroethylene or a polytetrafluoroethylene-elastomeric polymer blend, either alone or in combination, an elastic fiber, while maintaining the fiber under tension. The elastic fibers can be wound about the entire length of the tube while being maintained under the same of different degrees of tension. Furthermore, the elastic fibers may be wound about the tube under a higher degree of tension along locations adjacent the opposite ends the tubing.Type: GrantFiled: December 19, 1988Date of Patent: October 29, 1991Assignee: Baxter International Inc.Inventors: Roger Tu, Edwin Wang

Patent number: 5024671Abstract: A vascular graft at least partially formed from porous hollow fibers, with at least some of the porous hollow fibers being located adjacent an inner surface of the vascular graft. The vascular grafts of the invention have a relatively small pore size for promoting tissue growth while inhibiting bleeding during the healing process. The porous hollow fibers used to form the vascular grafts of the invention further provide a storage situs for temporarily holding a drug or other material for delivery into the blood stream during the healing process. This storage capability may also be used for holding an inert gas while providing the graft with greater resilency and cushioning characteristics than achievable with presently available vascular grafts.Type: GrantFiled: September 19, 1988Date of Patent: June 18, 1991Assignee: Baxter International Inc.Inventors: Roger Tu, David Chen, Wilfred F. Mathewson
