Abstract:
Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.
Abstract:
A method and device for radiating light used to capture an iris are provided. The device for radiating light to capture an iris of a user includes a lens unit including a lens array of arranged lenses, a light source configured to radiate light beams into the iris of the user via the arranged lenses by emitting the light beams toward the arranged lenses, and a controller configured to change positions of the arranged lenses based on a distance between the device and the iris, in which the lens array is positioned between the light source and the iris.
Abstract:
A dual purpose iris and color camera system is described provides good iris and color image capture in either IR or visible bands depending upon which type of image is being captured at that moment. For iris imaging the iris camera is capable of imaging in the 700 to 900nm wavelength range where the iris structure becomes visible. The iris camera is able to perform iris imaging outside with full sunlight. The iris camera requires only a low level of cooperation from the user, in that they must be within a range of distances away from the iris camera, must hold relatively still for a short period of time, and must face towards the camera. The iris capture process is fully automated once activated.
Abstract:
The invention comprises an imaging apparatus housed within a mobile device housing, and configured to enable multiple image acquisition modes. The apparatus includes an image sensor, a first optical assembly, a second optical assembly and a controller. The first optical assembly of the invention is positioned over a first image capture region of the imaging surface, and defines a first field of view - such that the first optical assembly images onto the first image capture region, any object plane within the first field of view. The second optical assembly is positioned over a second image capture region of the imaging surface, and defines a second field of view - such that the second optical assembly images onto the second image capture region, any object plane within the second field of view. The invention additionally includes a corresponding method for enabling multiple image acquisition modes in an imaging apparatus.
Abstract:
The invention comprises a method for configuring an imaging apparatus having an image sensor and an optical assembly. The method modifies a first imaging configuration of the imaging apparatus to achieve a second imaging configuration of said imaging apparatus, by interposing a refractive optical element between an image-side surface of the optical assembly and an imaging surface. In another embodiment, the method modifies a first imaging configuration of the imaging apparatus to achieve a second imaging configuration of said imaging apparatus by removing the refractive optical element from between an image-side surface of the optical assembly and an imaging surface. The invention additionally includes an imaging apparatus configured for switching from a first imaging configuration to a second imaging configuration. At least one of the first imaging configuration and the second imaging configuration may be configured for iris imaging.
Abstract:
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.
Abstract:
Methods and systems are disclosed for promoting use of research devices by a plurality of research device users or by a single research device user in compliance with at least one predetermined use criterion. Methods and systems are disclosed for monitoring use by a user of a research device in accordance with at least one predetermined use criterion.
Abstract:
An iris feature detector (110) includes a reflexive eye movement source (112-1124); a multiple image sensor (118); a controller (120), and a processor (122). The controller (120) causes the eye movement source (112-114) to cause rapid eye motion, and the sensor (118) to capture first and second iris images over a time interval in which only an iris can move in the first and second images. The processor (122) determines differences between the first and second images. The sensor (118) may be integrated with the processor (122). The integrated sensor/processor is not limited to iris feature detection, and may be used for edge detection for machine vision and other applications.
Abstract:
At least one wide field of view camera (3) and with an associated illuminator (6, 10) obtains sufficient images of a person to be identified so that x, y, z coordinates can be established for the expected position of that person's eye. The coordinates are used to direct a narrow field of view camera (16) and associated illuminators (21-23) to take an image of the eye (76, 78) that can be used for to identifying the person using iris verification and recognition algorithms. These illuminators are positioned and illuminated to eliminate or minimize specularities and reflections that obscure the iris (76).
