Abstract: The secure baggage claim apparatus and method centers on a dynamic merge conveyor unit that feeds into a standard baggage claim unit. The dynamic merge actively measures every space and every bag. Once the merge determines sufficient spacing for an individual bag, the dynamic merge will accelerate a bag into the open space on the baggage claim unit. Such dynamic merging greatly improves the throughput and capacity of baggage drop off and delivery. The entire baggage claim unit resides within the passenger sector of baggage claim. Current configurations allow bags to freely circulate between the secure and non-secure side of the baggage claim area. With the present invention, bags are prevented from circulating back and forth from the secure side to the non-secure side, which prevents an individual on the non-secure public side from placing a bag on a baggage claim unit where it will then be circulated and unscreened into the secure side for a baggage handler to retrieve such bag.

Abstract: An optical probe has multiple side-firing optical fibers which terminate in a linearly staggered fashion. A central fiber can be used as well. In diagnostic techniques, one fiber can be used as an emitter, while the others are used as receivers, or various fibers can be used as emitters and receivers at different times to form a map of the area. In therapeutic techniques, the treatment light can be emitted from the fibers in parallel or in sequence, and the fluence can be independently adjusted for each of the fibers. Therapy is readily combined with diagnosis and monitoring by directing the therapeutic light through the central fiber and using the side-firing fibers for reflectance and/or fluorescence spectroscopy before, during, and after therapy.

Abstract: A common-path, point-diffraction, phase-shifting interferometer uses a half wave plate having a diffractive element, such as pin hole. A coherent, polarized light source simultaneously generates a reference beam from the diffractive element and an object beam from remaining portions of the light going through the half wave plate. The reference beam has a nearly spherical wavefront. Each of the two beams possesses a different polarization state. The object and reference beams are then independently phase modulated by a polarization sensitive phase modulator that shifts phase an amount depending on applied voltage and depending on polarization state of the incident light. A polarizer is then used to provide the object and reference beams in the same polarization state with equal intensities so they can interfere to create an interferogram with near unity contrast.

Abstract: The present invention relates to a vehicle mounted printer station made up of a printer secured to a support surface tray that includes an adaptor capable of attaching the tray and printer to the top of a vehicle seat. The support surface is preferably a rectangular shaped plate with front, back and side edges along with top and bottom surfaces. The bottom surface is attached to the adaptor, the adaptor includes at least one attachment rod for securing the support surface to the vehicle seat. The attachment rods are sized to be received into receptacles provided in the top a vehicle seat designed for the vehicle headrest.

Abstract: A topical insecticide is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. In one preferred embodiment of the invention, the active ingredient of the insecticide formulation is an amine derivative, having a nitro-methylene group, a nitroamino group or a cyanoamino group, which can be formulated to have low toxicity and excellent insecticidal activity. One particularly suitable insecticide is 1-{(tetrahydro-3-furanyl)methyl}-2-nitro-3-methylguanidine(dinotefuran), an aldulticide that will kill adult fleas combined with methoprene.

Abstract: A short intense pulse of radiation is generated by shining radiation through a magneto-optical material and providing multiple stimulations to the material. The material is excited multiple times to rapidly change a property of the radiation, such as the angle of its polarization. The first excitation rotates the polarization in a first direction and the second excitation can rotate the polarization further. Alternatively the second excitation can bring the polarization back to its initial direction. Effect of lengthy relaxation times in the material cancel each other out and the pulse of light has a length that depends on the time difference between the two excitations and the spacing between them. This allows a pulse of light to be produced that has more rotation or has a shorter pulse width than the time for excitation plus the time for normal relaxation of the magneto-optical material.
