Publication number: 20160152324Abstract: A system, apparatus, device, and method for controlling fluid flow, including one or more devices generating one or more secondary fluid flow structures, wherein the fluid flow structures emanate from the aerodynamic or hydrodynamic surface, have a strength that is controlled independently of the primary flow, and enhance the aerodynamic or hydrodynamic force generated by primary flow predominantly by changing direction of said primary flow whether the flow is attached or separated from the surface, and/or interrupting and re-starting said primary flow forming regions that are not directly affected by the fluid flow structure regardless of whether said primary flow is attached or separated.Type: ApplicationFiled: April 1, 2014Publication date: June 2, 2016Inventors: Emilio Graff, Israel Wygnanski

Patent number: 8456645Abstract: Described is a method and system for fast three-dimensional imaging using defocusing and feature recognition is disclosed. The method comprises acts of capturing a plurality of defocused images of an object on a sensor, identifying segments of interest in each of the plurality of images using a feature recognition algorithm, and matching the segments with three-dimensional coordinates according to the positions of the images of the segments on the sensor to produce a three-dimensional position of each segment of interest. The disclosed imaging method is “aware” in that it uses a priori knowledge of a small number of object features to reduce computation time as compared with “dumb” methods known in the art which exhaustively calculate positions of a large number of marker points.Type: GrantFiled: December 1, 2011Date of Patent: June 4, 2013Assignee: California Institute of TechnologyInventors: Morteza Gharib, Emilio Graff, Francisco Pereira

Patent number: 8259306Abstract: A device and method for three-dimensional (3-D) imaging using a defocusing technique is disclosed. The device comprises a lens having a substantially oblong aperture, a sensor operable for capturing light transmitted from an object through the lens and the substantially oblong aperture, and a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object. The aperture may have an asymmetrical shape for distinguishing objects in front of versus in back of the focal plane. The aperture may also be rotatable, where the orientation of the observed pattern relative to the oblong aperture is varied with time thereby removing the ambiguity generated by image overlap. The disclosed device further comprises a light projection system configured to project a predetermined pattern onto a surface of the desired object thereby allowing for mapping of unmarked surfaces in three dimensions.Type: GrantFiled: February 8, 2011Date of Patent: September 4, 2012Assignee: California Institute of TechnologyInventors: Morteza Gharib, Emilio Graff, Francisco Pereira
