Abstract: A swept distance between a subject and a plurality of cameras provides a plurality of raw images. Focused portions of the raw images are fused to generate a synthetic image and a distance image. A projection of the synthetic image and the distance image yields a panoramic image.

Abstract: An acquisition system for obtaining images of a fingerprint from a finger, or marks of another kind of target. The system may have two or more cameras positioned at different directions towards the target. Each camera may have a light source for illuminating the target from a direction different than that of the respective camera. The cameras may take sequences of images of the target at different focuses as the whole target might not be in focus in one image due to a depth of focus being less than the depth of the target. Portions of the images showing the target in focus may be cut from the images and stitched together to result in an image revealing virtually the whole target in focus. This target may be a fingerprint to be rolled out on or in a two dimensional medium for analysis, identification, storage, and so on.

Abstract: A trending system and method for trending data in a mechanical system is provided. The trending system includes a sliding window filter. The sliding window filter receives a data set of data points generated by the mechanical system. The sliding window filter partitions the data set into a plurality of data windows, and uses the data windows to calculate upper and lower confidence bounds for the data set. Specifically, the sliding window filter calculates an upper confidence bounds and lower confidence bounds for each data point using each of the multiple data windows that includes the data point. The sliding window filter then selects the upper confidence bounds and the lower confidence bounds that results in the smallest mean prediction confidence interval for that data point. This results in a smoothed estimated trend for the data set that can be used for prognostication and fault detection.

Abstract: A method and system for eye-safe near infra-red (NIR) optical imaging illumination. An eye of an intended subject are imaged with visible light or NIR light at an unconditionally eye-safe illumination level and the maximum permissible eye-safe NIR illumination that can be applied to the eye is determined from the captured images. The eye of the intended subject can then be illuminated with at least one substantially maximal NIR light pulse having a pulse intensity and duration selected to provide the substantially maximum permissible eye-safe NIR illumination intensity at the eye. NIR light pulse illumination can be inhibited in response to detection of other subjects either within the vicinity of a volume extending between an NIR illuminator illuminating the eye and the intended subject. The likelihood that an intended subject has been recently illuminated can also be determined and statistical measures can be used to avoid re-illuminating subject unnecessarily.

Abstract: A duplex camera with common face and iris imaging optics locates an iris in a scene and images the iris without requiring multiple camera alignment or a rapid zoom capability. A wavelength selective mirror separates the light from an imaged scene into visible and infrared components. The visible component supplies a face image in which an iris location can be determined. Visible light optics and a visible light sensor array provide a scene image to an image processor that determines the iris location. Infrared optics and an infrared sensor produce an iris image centered on the iris location. Upon determining an iris location, a motorized stage can position the iris image in the infrared sensor. The common face and imaging optics allow the image sensors to be permanently aligned to one another.

Abstract: An agile illumination apparatus for use in biometric authentication is disclosed. A controlled spot flash strobe forms and focuses a narrow illuminating beam so as to cover an area of interest for a biometric authentication of a target with a spot of light of constant size regardless of a distance of the target from the controlled spot flash strobe. A positioner can then be utilized to steer the narrow illuminating beam to a target in a monitored space. The spot size is kept constant and its irradiance distribution is kept uniform in order to deliver a constant amount of energy to the target irrespective of the distance, wherein the controlled spot flash strobe automatically reduces its power as the target moves closer to the controlled spot flash strobe in order to maintain a constant exposure value and provide for enhanced biometric authentication of the target.

Abstract: A system and method for laser source detection. An exemplary embodiment of the system includes a first array of lenses, a second array of opto devices (including light sources and light detectors), and at least one processor. By positioning the array of lenses to determine the lens position at which energy from an incoming laser is greatest on the light detectors, the approximate location of the laser source may be determined. Upon determining the source, responsive action may be taken. If the incoming laser is from a friendly party, a friendly-party notification may be provided. If the incoming laser is from an enemy, reciprocal targeting or false reflections may be employed.

Abstract: A method and apparatus for automatically focusing a camera that may rely upon ambient light for auto focusing and flash illumination for image capture. A correction factor may be determined that is based at least in part on a range between the camera and a desired subject. The camera focus may be adjusted in accordance with the correction factor prior to capturing a capture image using flash illumination.

Abstract: A camera system may be used to capture iris images of targeted people who may be unaware of being targeted and hence their movement may not be constrained in any way. Iris images may be used for identification and/or tracking of people. In one illustrative embodiment, a camera system may include a focus camera and an iris camera, where the focus camera is sensitive to ambient light or some spectrum thereof, and the iris camera is sensitive to infrared or some other wavelength light. The focus camera and the iris camera may share an optical lens, and the focus camera may be used to auto-focus the lens on a focus target. A beam splitter or other optical element may be used to direct light of some wavelengths to the focus camera for auto-focusing the lens, and other wavelengths to the iris camera for image capture of the iris images.

Abstract: A system using face and iris image capture for recognition of people. The system may have wide field-of-view, medium field-of-view and narrow field-of-view cameras to capture images of a scene of people, faces and irises for processing and recognition. Matching of the face and iris images with images of a database may be a basis for recognition and identification of a subject person.

Abstract: Integrated modeling and symbolic manipulation is leveraged for the derivation, construction, maintenance, and reuse of application-independent models. Related models created for different applications share a common ancestry and maintain model consistency while enabling the models to share information about the process. Environment independent proper ancestor models (PAMs) are created for generic components of a process, such as a distillation or flash column. Models underlying an application may be comprised of various representations of multiple such processes corresponding to many different physical components. PAMs contain symbolic representations of different sub processes that occur within a process or component. A user makes assumptions about the component, by indicating how sub processes are to be considered or not considered. PAMs are then modified in accordance with the assumptions to derive a specific environment model (SEM).
