Patent number: 8983146Abstract: A multimodal biometric identification system captures and processes images of both the iris and the retina for biometric identification. Another multimodal ocular system captures and processes images of the iris and/or the from both eyes of a subject. Biometrics based on data provided by these systems are more accurate and robust than using biometrics that include data from only the iris or only the retina from a single eye. An exemplary embodiment emits photons to the iris and the retina of both eyes, an iris image sensor that captures an image of the iris when the iris reflects the emitted light, a retina image sensor that captures an image of the retina when the retina reflects the emitted light, and a controller that controls the iris and the retina illumination sources, where the captured image of the iris and the captured image of the retina contain biometric data.Type: GrantFiled: January 29, 2013Date of Patent: March 17, 2015Assignee: MorphoTrust USA, LLCInventors: Marc D. Friedman, Pablo Casaverde, Don Yansen, Tim McNerney, Yasunari Tosa, David Usher, Nicholas A. Accomando, David Muller, Gregory L. Heacock, John Marshall

Patent number: 8864985Abstract: A method and apparatus for operating on skimmed oil/water picked up from a body of water to separate the oil from the water and discharge the oil-free water back into the body of water, first feeds the skimmed oil/water into a gravity settling tank wherein the oil tends to settle above the water, removing relatively oil-free water from the bottom of the tank and measuring its oil content with an oil concentration sensor, and either returning the oil/water flow to the settling tank for further processing if the measured concentration of oil exceeds predetermined limits or discharging the water back into the body of water if the oil concentration is measured to be less than the predetermined value.Type: GrantFiled: August 20, 2013Date of Patent: October 21, 2014Inventor: David Usher

Patent number: 8644562Abstract: Biometric systems capture and combine biometric information from more than one modality, employing digital processing algorithms to process and evaluate captured images having data for a biometric characteristic. Such digital algorithms may include a pupil segmentation algorithm for determining a pupil image in the captured image, an iris segmentation algorithm for determining an iris image in the captured image, an eyelid/eyelash segmentation algorithm for determining an eyelid/eyelash image in the captured image, and an algorithm for measuring the focus on the iris. Some embodiments employ an auto-capture process which employs such algorithms, in part; to evaluate captured images and obtain the best possible images for biometric identification.Type: GrantFiled: April 30, 2012Date of Patent: February 4, 2014Assignee: MorphoTrust USA, Inc.Inventors: Yasunari Tosa, David Usher, Nicholas A.

Patent number: 8577093Abstract: A system for multimodal biometric identification has a first imaging system that detects one or more subjects in a first field of view, including a targeted subject having a first biometric characteristic and a second biometric characteristic; a second imaging system that captures a first image of the first biometric characteristic according to first photons, where the first biometric characteristic is positioned in a second field of view smaller than the first field of view, and the first image includes first data for biometric identification; a third imaging system that captures a second image of the second biometric characteristic according to second photons, where the second biometric characteristic is positioned in a third field of view which is smaller than the first and second fields of view, and the second image includes second data for biometric identification. At least one active illumination source emits the second photons.Type: GrantFiled: February 20, 2012Date of Patent: November 5, 2013Assignee: Identix IncorporatedInventors: Marc D.

Publication number: 20130245536Abstract: A method for controlling activation of a cross-linking agent applied to an eye includes applying the cross-linking agent to a selected region of a cornea of the eye and initiating cross-linking activity in the selected region by activating the cross-linking agent with pulsed light illumination. The pulsed light illumination has a selectable wavelength, irradiance, dose, and on/off duty cycle. The wavelength, the irradiance, the dose, and the on/off duty cycle are adjusted in response to a determination of photochemical kinetic pathways for cross-linking activity and to control photochemical efficiency, depth of cross-linking, and density of cross-linking.Type: ApplicationFiled: March 15, 2013Publication date: September 19, 2013Applicant: Avedro, Inc.Inventors: Marc D.

Publication number: 20120310083Abstract: Devices and approaches for monitoring time based photo active agent delivery or photo active marker presence in an eye. A monitoring system is provided for measuring the presence of a photo active marker by illuminating the eye so as to excite the photo-active marker and then observing characteristic emission from the photo active marker. Example systems incorporate Scheimpflug optical systems or slit lamp optical systems to observe cross sectional images of an eye to monitor instantaneous distribution, diffusion pattern, and rate of uptake of a photo active agent applied to an eye. Systems and methods further allow for utilizing the monitored distribution of photo active agent in the eye as feedback for a cross-linking system.Type: ApplicationFiled: June 4, 2012Publication date: December 6, 2012Applicant: Avedro, Inc.Inventors: Marc D.
