System and method for locating and performing fine grained classification from multi-view image data
Patent number: 10534960Abstract: Some embodiments of the invention provide a method for identifying geographic locations and for performing a fine-grained classification of elements detected in images captured from multiple different viewpoints or perspectives. In several embodiments, the method identifies the geographic locations by probabilistically combining predictions from the different viewpoints by warping their outputs to a common geographic coordinate frame. The method of certain embodiments performs the fine-grained classification based on image portions from several images associated with a particular geographic location, where the images are captured from different perspectives and/or zoom levels.Type: GrantFiled: April 3, 2017Date of Patent: January 14, 2020Assignee: California Institute of TechnologyInventors: Pietro Perona, Steven J.

Patent number: 6613700Abstract: A method for spin coating high viscosity materials. Two dispense steps are used. The first dispense step dispenses a small amount (102) of high viscosity material at the center of the wafer (100). A high-speed wafer rotation spreads the material to form a thin layer (104) to prime the surface of the wafer (100) and lower the surface tension without regard to uniformity. A second dispense step occurs at lower RPM and coats (108) the wafer (100) more uniformly.Type: GrantFiled: November 30, 2001Date of Patent: September 2, 2003Assignee: Texas Instruments IncorporatedInventors: David C.

Patent number: 6408873Abstract: A flush valve for use with urinals or water closets includes a hollow valve body having an inlet, an outlet, and a valve seat therebetween. There is a piston assembly movable in the hollow valve body to a closing position on the valve seat to control flow through the valve. A pressure chamber is above the piston assembly for holding it on the valve seat. There is a bypass passage to the piston assembly to connect the inlet with the pressure chamber to provide fluid to move the piston assembly to the closing position. The bypass passage includes a filter and an orifice, with the filter including multiple filters in series between the inlet and the bypass.Type: GrantFiled: July 24, 2000Date of Patent: June 25, 2002Assignee: Sloan Valve CompanyInventors: David C.
