    • A tunable infrared detector is provided that includes a substrate, a bottom wavelength detector formed over the substrate, a top wavelength detector formed over the first wavelength detector layer, and an interferometer filter formed over the top wavelength detector layer and the bottom wavelength detector layer. The interferometer filter is operatively configured to pass a first wavelength associated with a first portion of a predetermined band and a second wavelength associated with a second portion of the predetermined band to the top wavelength detector. The top wavelength detector is operatively configured to detect each wavelength associated with the first portion of the predetermined band and to transmit each wavelength associated with the second portion of the predetermined band to the bottom wavelength detector. The bottom wavelength detector is operatively configured to detect each wavelength associated with the second portion of the predetermined band.
    • 提供了一种可调谐红外检测器,其包括衬底,形成在衬底上的底部波长检测器,形成在第一波长检测器层上的顶部波长检测器,以及形成在顶部波长检测器层和底部波长检测器层上的干涉仪滤波器。 干涉仪滤波器被可操作地配置成将与预定频带的第一部分相关联的第一波长和与预定频带的第二部分相关联的第二波长传递到顶部波长检测器。 顶部波长检测器被可操作地配置为检测与预定波段的第一部分相关联的每个波长,并将与预定波段的第二部分相关联的每个波长传输到底部波长检测器。 底部波长检测器可操作地配置为检测与预定波段的第二部分相关联的每个波长。

    • A device for the replacement of wheels on trains comprising a generally flat framework having a longitudinal opening extending therethrough, a first wheel receiving area rigidly affixed to the framework for abutting a surface of a wheel, and a second wheel receiving area rigidly affixed to the framework and disposed distal from the first wheel receiving area on the framework. The longitudinal opening receives the periphery of a train wheel. The framework includes a first longitudinal member, a second longitudinal member, and a transverse member rigidly connected across the longitudinal members for maintaining the longitudinal members in parallel alignment. The longitudinal opening has a width sufficient, in combination with the thickness of the longitudinal members, to cause the periphery of the train wheels to raise above the top surface of a railroad track. The wheel receiving areas comprise a plurality of abutment members positioned for the receipt of train wheels removed from a train and of replacement train wheels. Pull rings are rigidly affixed at the ends of the framework for attachment to an external pulling mechanism.
    • 一种用于更换火车上的车轮的装置,包括具有延伸穿过其中的纵向开口的大致平坦的框架,刚性地固定到框架上用于邻接车轮表面的第一车轮接收区域和刚性地附接到车架的第二车轮接收区域 并且远离框架上的第一轮接收区域设置。 纵向开口接收轮系的周边。 框架包括第一纵向构件,第二纵向构件和刚性地连接在纵向构件上的横向构件,用于将纵向构件保持为平行对准。 纵向开口具有足够的宽度,与纵向构件的厚度相结合,使得轮系的周边在铁轨的顶表面上方升高。 车轮接收区域包括多个抵靠构件,其定位成用于接收从列车和替换轮系车轮移除的列车车轮。 拉环刚性地固定在框架的端部以附接到外部拉动机构。
