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:
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 support vehicle particularly for use with aircraft wherein the vehicle, in a non-operative mode is maintained at low overall height and size for ease of transport and storage but includes an extendable main boom having attachment means at its free end enabling a plurality of different service facilities to be releasably secured thereto and a pivotable draw bar and hitch assembly enabling the hitch assembly to be operable at a plurality of different heights.
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:
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.
Abstract:
A method of forge welding laminates of titanium and titanium alloys includes interleaving first and second pluralities of metal pieces in an enclosure, filling the enclosure with an inert gas, heating the enclosure and the first and second pluralities of metal pieces, and mechanically pressing the enclosure on a first axis with a force sufficient to cause the first and second pluralities of metal pieces to forge-weld together. The first and second pluralities of metal pieces may be metallurgically dissimilar from each other, and may each comprise a percentage of titanium.
