Abstract: The present disclosure is directed generally to simultaneous dual-band systems and methods. A dual-band system as disclosed herein includes a plurality of pixels. Each pixel comprising a first absorber layer; a first intervening layer located adjacent the first absorber layer; a second absorber layer located adjacent to the first intervening layer; and a second intervening layer located adjacent to the second absorber layer. The plurality of pixels includes a first subset of pixels for detecting light in a first band and a second subset of pixels for detecting light in a second band. Carriers created in the first absorber layer of the first subset of pixels are collected via the first contact layer. Carriers created in the second absorber layer of the second subset of pixels are collected via the second contact layer and carriers created in the first absorber layer remain uncollected.

Abstract: A device for marking the proper position for the threaded fasteners used to secure the leaves of a butt hinge to and between opposable surfaces, which surfaces are to be made hingably movable relative to each other is disclosed. The device includes at least one hinge leaf locator plate which is sized and shaped to conform to the leaf of a hinge whose fastener positions are to be marked. The locator plate contains a series of sharp pointed pins which are arranged thereon and spaced apart from one another in the same manner as the centerline of the fastener holes located in the leaves of the hinge which is to be mounted to and between the opposable surfaces. The series of pins have pointed end portions which project in opposite directions from the locator plate to permit marking by impressions of the pin heads on both opposable surfaces simultaneously for maximum accuracy.
