Abstract: A system and methods for optically detecting a target gas are disclosed and described. An imaging system can include a narrow-band optical interference filter with a center wavelength that corresponds to a feature in an absorption spectrum of a target gas at a normal angle of incidence. An optical component can receive incoming light from the target gas that has passed through the narrow-band optical interference filter, where the narrow-band optical interference filter is tilted relative to the optical component, which tilt shifts the wavelength of light from each target point that is able to pass through the narrow-band optical interference filter. A camera can receive the incoming light that has been focused by the optical component. Multiple image frames are collected for different orientations of the system with respect to the target and analyzed to perform hyperspectral charactetization of target gas absorption.

Abstract: An improved process for regenerating ion exchange resin, includes a regeneration step of displacing captured ions from the resin to regenerate its ion-capture functionality, followed by one or more fluid-employing post-regeneration steps such as a fluid displacement or rinse, a fluid transporting or mixing, and a rinse down to quality. To avoid problems of early leakage of weakly held ions such as boron, the post-chemical or postdisplacement steps use water that is essentially free of boron, or otherwise avoid localized contamination in the regenerated resin which is used in bottles or beds (30). A two-stage polish may be operated with modified lead/lag bottles. A detector (D) for an indicator condition (conductivity, silica breakthrough) between stages determines when to shift the lag bottle forward, and periodically both bottles are replaced.

Abstract: An electromagnet coil comprising Litz wire windings and power leads without break or interruption is cooled by a perfluorinated liquid by sensible and phase change heat transfer in a closed system. The electromagnet coil may be housed in a pentagonal or hexagonal pressure vessel to allow high packing densities in an array or helmet configuration. The helmet is then lowered over a human cranium for transcranial electromagnetic stimulation. The Litz wire windings reduce the power and voltages required for operation, yet allow production of over 2 T of accurately directed magnetic pulses for direct nerve or neuron stimulation. The perfluorinated liquid maintains the temperature of the helmet to less than 35-40° C., ensuring a comfortable temperature device for a human test subject. A utility cable connects the helmet to an external cooling unit and an external power supply.

Abstract: A wide bore, high field superconducting magnet. The superconducting magnet has a plurality of superconducting coils impregnated with epoxy and nested within each other. An innermost one of the nested coils has a bore therethrough that defines a bore width of the magnet. The bore width is greater than approximately 100 millimeters. The nested coils are electrically connected in series and cooled to an operating temperature less than approximately 4 degrees K. The magnet also has external reinforcements on the coils that are applied prior to impregnating the coils with epoxy. An active protection circuit protects the coils in response to a quench in the magnet. The protection circuit includes heater elements positioned in thermal contact with the coils prior to impregnating the coils with epoxy. The magnet further has lead supports for supporting the lead wires with epoxy that extend from the coils.

Abstract: A method and device implementing a downloadable operatively connected to a plurality of gaming machines either by a direct communications link or through the use of one or more site controllers or PCs. Each gaming machine and site controller or PC contains two executable spaces, one of which typically contains the software image currently being implemented by the device. The other executable space is designated to receive from the central system a new software image that will be utilized by the device. The central system transfers a new image to be executed, via packet encrypted communications, to a networked device which stores the image in an executable space, while continuing to run the currently designated image. Upon instruction from the central system, the device switches over to the new image, allowing one or more machines to implement a software upgrade on a continuous basis.
