A one-to-many identification system for access control allows a search rate of up to ˜1:30,000 in a real time. The system uses a very fast pattern based screening algorithm followed by a fast minutiae based screening algorithm. A fused score of both algorithms is used as a decision metric to screen out a vast majority of all the templates after the second stage. The remaining templates are sent to a full minutiae based algorithm to obtain a minutiae comparison score. If the result is still inconclusive after the third stage, a full pattern based algorithm is run, and its score is fused with the minutiae comparison score. The system also uses an adaptive classification technique which minimizes a distance between each template and a number of templates. The system can be realised as a standalone unit or on a server.

A system that employs transmission-based detection techniques to determine the presence or concentration of an analyte within a test sample is provided. Specifically, the optical detection system contains an assay device that is positioned in the electromagnetic radiation path defined between an illumination source and solar panel. To enhance the sensitivity and signal-to-noise ratio of the system without significantly increasing costs, the distance between the illumination source and/or solar panel and the assay device is minimized. The illumination source and/or solar panel may also be positioned directly adjacent to the assay device. In addition, the system may be selectively controlled to reduce reliance on external optical components, such as optical filters or diffusers.

A method for producing a high resolution detector array so as to provide very high packing fraction, i.e. the distance between scintillator elements is minimized so the detector efficiency will be higher than is currently achievable. In the preferred embodiment of the present invention, the fabrication methodology is enhanced by handling scintillator bars rather than single crystals when gluing on an optical film as well as polishing the scintillator. Namely, a scintillator boule is cut into wide bars of a selected dimension, for example 30 mm, which are then acid etched or mechanically polished. A selected number, N, of these scintillator bars can then be glued together with sheets of optical film between each bar (coating the scintillator disks and optical film with an adhesive of a selected index of refraction). The glued bar block is then cut again into bars in a perpendicular direction, and these new scintillator-optical film bars are polished. Finally, a selected number, M, of these scintillator-optical film bars are glued together with sheets of optical film between each bar; thus creating a polished N×M scintillator-optical film array, (where M may or may not be equal to N), without having to handle individual scintillator crystals or small pieces of optical film.

A target type thrust reverser is provided for reversing the thrust of jet engines, particularly on aircraft. The thrust reverser preferably has a plurality of doors that occupy a stowed position about the nozzle of the jet engine until deployed. In the stowed position, the doors are out of the exhaust stream of the jet engine. The doors are mounted to pivot joints on the rear portions of the doors. To deploy the thrust reverser, actuators connected to the pivot joints cause the pivot joints to translate linearly aft, and link rods attached to the forward portions of the doors cause the doors to pivot about the sliding pivot joints. In this manner, the distance between the doors and the engine exhaust nozzle is minimized during deployment, which enables significant weight savings due to reduced loads and fewer parts. A novel lock is also provided for simultaneously locking the thrust reverser doors and the actuators.

Such a chip scale image sensor includes a first substrate on which a peripheral circuit is formed, a second substrate which is stacked on the first substrate and on which a pixel array is formed, and global interconnections for electrically connecting the pixel array and the peripheral circuit.
