Abstract: Systems, methods, and devices involving segmented radiation detectors are provided. For example, a segmented radiation detector may include a segmented scintillator and an optical-to-electrical converter. The segmented scintillator may have several segments that convert radiation to light, at least one of which may detect radiation arriving from an azimuthal angle around an axis of the segmented scintillator. The optical-to-electrical converter may be coupled to the segmented scintillator. The optical-to-electrical converter may receive the light from the segments of the segmented scintillator and output respective electrical signals corresponding to the amount of radiation detected by each segment.

Abstract: A retainer arrangement is disclosed for securing two or more panels with highly dissimilar coefficients of thermal expansion to an underlying support structure. In automotive applications, for example, the retainer allows the use of body panels of a material such as flexible plastic having a differing coefficient of thermal expansion than the support structure, typically constructed of steel, without inducing distortion, i.e., rippling or buckling of the body panel, as the assemblage is subjected to widely varying temperatures. The retainer comprises a strip mounted to the support structure and is configured to hold an edge of the overlay body panel to perform the retention function, allowing relative linear movement between the retainer and the overlay body panel.In one embodiment, the retainer strip has a flange portion mounted to an outer fender and also has an extended portion overhanging the flange and adapted to receive an offset edge of the overlying body panel.
