Publication number: 20230353368Abstract: Biometric data such as iris, facial, or fingerprint data may be obtained from a user. A public code may be generated from the biometric data, but does not obtain any of the biometric data or information that can be used to identify the user. The public code includes information that can be used to extract from the biometric data a biometric code that is suitable for bitwise comparison. Neither the underlying biometric data nor information from which the biometric data may be determined is stored as only the public code and the actual biometric feature of the user is required to generate the biometric code.Type: ApplicationFiled: February 10, 2023Publication date: November 2, 2023Inventor: Gilles Mathieu

Publication number: 20230246839Abstract: A biometric capture is performed to capture multiple regions of a biometric modality of interest, such as regions of a user's face. A complex representation of the user's biometric data is generated, such that each data point within the complex representation is based on biometric information from multiple of the captured regions. Information that later allows reconstruction of the complex representation from another capture of the user's biometric information is stored in a public code that does not include any of the underlying biometric data from the user or information that can be used to derive the underlying biometric data.Type: ApplicationFiled: March 24, 2023Publication date: August 3, 2023Inventor: Gilles Mathieu

Patent number: 8849639Abstract: An example system includes interconnected modeling modules that share knowledge to create a unified earth model dynamically representing a subsurface site. The system models and may simulate subsurface operations associated with, for example: hydrocarbon production and stimulation, natural gas storage, carbon capture and storage, aquifer maintenance, geothermal energy production, and in-situ leachable ore processing. The system integrates a reporting module, and also an economic module to evaluate cost versus benefit of each subsurface operation. A related example method for performing subsurface engineering includes generating a model of a subsurface site including a geological horizon, obtaining an offset relative to the geological horizon, and locating an operation based on the offset. When field data update the model in real time, positions of 3D objects and 3D surfaces are dynamically updated in the model, including the positions of the modeled operations.Type: GrantFiled: September 17, 2010Date of Patent: September 30, 2014Assignee: Schlumberger Technology CorporationInventors: Alan Lee Brown, Simon David Bulman, Martin Crick, Gilles Mathieu, Russ Sagert, Peter Wardell-Yerburgh

Patent number: 8594388Abstract: (A2) An extended depth of field (DOF) imaging system (10) is disclosed that has a corresponding extended depth of focus (DOF?) by virtue of its optical system (20) having a select amount of spherical aberration. The imaging system has an image processing unit (54) adapted to process the raw images and perform contrast enhancement to form processed images. The image processing includes restoring the defocused modulation transfer functions (MTFs) using a gain function (G) and the amount of defocus. The imaging system can include an illumination system (60) that illuminates the object being imaged to establish a distance (DH) between the optical system and the object, where distance DH is used in the restoring of the MTF. An iris-recognition (I-R) system based on the enhanced DOF imaging system is also disclosed.Type: GrantFiled: February 29, 2008Date of Patent: November 26, 2013Assignee: FM-Assets PTY LtdInventor: Gilles Mathieu

Patent number: 8488044Abstract: An extended depth of field (EDOF) imaging system that has a corresponding extended depth of focus (EDOF?). The imaging system has an optical system consisting of a single lens element and an objectwise aperture stop arrange substantially at a zero-coma axial position. The single lens element is configured so that the optical system has a select amount of spherical aberration (SA) in the range 0.2??SA?2?, where ? is an imaging wavelength. The single lens element generates an amount of axial chromatic aberration that increases the EDOF while decreasing the average MTF of the optical system relative to the optical system having no chromatic aberration. The imaging system has an image sensor for forming a digitized raw image of an object.Type: GrantFiled: February 17, 2009Date of Patent: July 16, 2013Assignee: Global Bionic Optics Pty Ltd.Inventor: Gilles Mathieu
