Abstract: The disclosure relates to water treatment systems that may be used to remove impurities from water, particularly systems that inserted at the point of entry of a water supply into a building.

Abstract: The disclosure relates to pumping systems that may be used to pump fluids in variety of situations where it is important to maintain fluid flow. The systems include at least two pump assemblies. At least one controller, an inlet, an outlet, and a stand.

Abstract: Portable oscillating compression systems including a compressor for compressing air; an accumulator tank for receiving and storing the compressed air from the air compressor; an air pressure adjustment module for modulating pressure of the compressed air when the compressed air exits the accumulator tank; a valve body assembly attached to the accumulator tank, a plurality of inflatable cuffs connected to the valve body assemble for receiving the compressed air from the valve body assembly; a controller for controlling the valve body assembly; a power supply; and a housing for containing said system.

Abstract: A scintillator, for use in a radiation imaging device, has a light-emitting face, a radiation receiving face, and a perimeter extending between the light-emitting face and the radiation receiving face, the perimeter including an edge, the edge having an edge thickness. The scintillator emits scintillation light from the light emitting face in response to radiation incident on the radiation receiving face. The scintillator has one or more light guides formed therein with guides within a peripheral region being deeper than guides in a non-peripheral region.

Abstract: A single photon emission computed tomography system includes a detector assembly adjacent a field of view and a collimating assembly disposed between the detector assembly and the field of view. The collimating assembly includes at least two spaced-apart collimating vanes of photon-attenuating material. The system further includes a photon-blocking member disposed between the field of view and the detector. The blocking member has an aperture defined therethrough. The system further includes a mask disposed adjacent the detector assembly having at least one aperture defined therethrough. A displacement actuator moves the photon-blocking member relative to the detector assembly.

Abstract: Apparatus and methods for shaping a surface of a material are described. An example method comprises providing one or more shaping elements, softening the material, and urging the one or more shaping elements against the material so as to form one or more grooves in the material. The configuration of shaping elements can be adjusted to provide a desired pattern of grooves in the surface. The method can be applied to inorganic crystals in a high temperature plastic state, avoiding the problems associated with conventional sawing techniques.

Abstract: An apparatus for imaging a field of view, according to an embodiment of the present invention, comprises an x-ray source positioned adjacent to the field of view, a source mask located between the x-ray source and the field of view having at least one source aperture defined therethrough, and an emission detector, such as a gamma camera, adjacent to the field of view. The apparatus may allow substantially concurrent x-ray imaging and gamma imaging of the field of view.

Abstract: A single photon emission computed tomography system includes a base for supporting a patient and a detector assembly adjacent the field of view. The detector assembly detects photon strikes from the field of view. A photon-blocking member is disposed between the field of view and the detector and has an aperture slot that allows passage of photons aligned with the slot. A collimating assembly includes a plurality of collimating vanes formed of photon-attenuating material. A support assembly supports the collimating assembly and includes a first support member and a second support member with the collimating assembly being disposed therebetween. An adjustment assembly includes a first adjuster operable to adjust a first distance between the collimating assembly and the first support member and a second adjuster operable to adjust a second distance between the collimating assembly and the second support member.

The scintillator emits scintillation light from the light emitting face in response to radiation incident on the radiation receiving face. The scintillator has one or more light guides formed within a peripheral region of the scintillator proximate to the edge. The light guides can improve the positional accuracy of a radiation imaging device including the scintillator.
