Abstract: Various embodiments of a facial recognition system are provided. In one embodiment, a processor determines a value for a lighting parameter associated with a captured facial image, determines whether any previously obtained images in a biometric database includes a similar value for the lighting parameter and, if not, stores the newly captured image in the database along with the lighting parameter value. In another embodiment, the processor calculates a score indicative of the likelihood that the face in the captured facial image is identical to the face of a previously obtained image in the database, determines whether the score exceeds a threshold value and, if so, generates a signal indicating a match. The processor adjusts the threshold based on one or more parameter values.

Abstract: A method and an apparatus for its practice to render radioactive earth materials such as NORM and TENORM more suitable for disposal, includes detecting the level of radioactivity in such earth materials as well as detecting the specific energy of radiation to identify specific isotopes within the earth materials. The radioactive earth materials are diluted with appropriate materials suitable for disposal. Preferably, the radioactivity of the diluted material is monitored to assure the resulting mixture is suitable for the disposal intended.

Abstract: An apparatus for the indirect cooling of a silicon drift detector (SDD) includes an enclosure with a vacuum maintained therein, at least one SDD module that generates substantially no heat positioned within the enclosure, a cooling engine positioned remote from the SDD module within the enclosure for cooling the SDD module, whereby heat is generated by the cooling engine, a thermal conduction device comprising a first end thermally coupled to the cooling engine and a second end thermally coupled to the SDD module and a heat removal device thermally coupled to the cooling engine. The cooling engine indirectly cools the SDD module by transferring thermal energy through the thermal conduction device from the SDD module and the heat removal device dissipates the heat generated by the cooling engine to the environment surrounding the enclosure. A method for indirectly cooling a radiation detector is also provided.

Abstract: A superconducting magnet assembly having two individual magnetic coils contained in separate vacuum jackets with a radiation shield between each magnet and its respective vacuum jacket. Each magnet coil is cooled to superconducting temperature by direct coupling to the second stage of a separate two stage closed cycle refrigerator. A first stage of each refrigerator cools an associated radiation shield.
