    摘要： A two dimensional (2D) collimator assembly and a detector system employing a 2D collimator assembly. More specifically, a collimator assembly is provided, having elements extending in the x and z-planes of a detector system. The 2D collimator assembly includes a number of blades arranged in parallel. Each of the blades includes fins extending from one or both sides of the body of the blade. The fins are coupled to each adjacent array to form the 2D collimator assembly.

    摘要： The present invention is a directed to a CT detector for a CT imaging system that incorporates a segmented optical coupler between a photodiode array and a scintillator array. The segmented optical coupler also operates as a light collimator which improves the light collection efficiency of the photodiode array. The segmented optical coupler is defined by a series of reflector elements that collectively form a plurality of open cells. The open cells form light transmission cavities and facilitate the collimation of light from a scintillator to a photodiode. The cavities may be filled with optical epoxy for sealing to the photodiode array.

    摘要： The present invention is directed to a collimator assembly defined by a series of multi-piece collimator elements or plates that extend along at least one dimension of a scintillator pack. Each collimator element has a collimating component and a shielding component that are structurally independent from one another. The collimating components may be connected to the shielding components or separated by a small air gap. The shielding components are wider than the collimating components but the collimating components have a greater height. With this construction, the collimator assembly optimizes collimation and shielding with lower material requirements and reduced overall size.

    摘要： A dual belt conveyor includes a pair of flexible endless loop conveyor belts arranged at an incline with a lower flight of the upper belt in face-to-face conveying relationship with an upper flight of the lower belt to retain and convey granular material between the belts. Drive pulleys are connected to both belts to move the belts at the same speed, and the conveying flights of the belts are journaled through a trough which forces the belts into a curved concave orientation between the side edges with the upper belt biased downwardly into engagement with product on the lower belt to retain product therebetween.

    摘要： An improved price display system for a multi-level merchandising machine in which the prices of articles at the respective levels are electronically displayed individually at locations immediately adjacent to the levels. Both the prices and the displays can be changed in a rapid and expeditious manner from a station within the machine cabinet. In addition, both the mode of operation and the compartment size of a level can be displayed and changed. The system may be provided with a timer for automatically changing all prices at a predetermined time. The system employs a small number of conductors to control a large number of displays.
