摘要： An improved electromagnetic audible signal device has a coil and an associated magnetic core. A flexible striker arm carrying a movable magnetic contact is positioned above the core. A multiconvoluted diaphragm is located above the movable contact and the striker arm. The contact periodically impacts against this diaphragm generating an audible signal. The invention includes a spring and screw arrangement for linearly adjusting the gap between the core and striker arm. The same spring also serves to restore vibrational mechanical energy to the system which would normally be lost to the housing.

摘要： An optical correlator system having a plurality of reflective optical components, both active and passive, positioned (1) between a source of electromagnetic radiation, such as a visible beam of coherent light, and an output detector array, and (2) around an asymmetrical perimeter of a planar support body to develop an asymmetrically folded optical axis or path wholly within the body where the path is traversed by the beam SO THAT information processed by the active optical components along the optical path and imparted to the optical beam enable the optical detection of an unknown object at the detector array which is then subject to an identification process.
摘要翻译：一种光学相关器系统，其具有多个反射光学部件，主动和被动，位于（1）电磁辐射源（例如相干光的可见光束）和输出检测器阵列之间，（2）围绕不对称的平面支撑体的周边以形成完全在体内的不对称折叠的光轴或路径，其中路径被光束SO穿过。由主动光学部件沿着光学路径处理并被赋予光束的信息使得能够进行光学检测在检测器阵列处的未知物体，然后进行识别处理。

摘要： In an optical correlator system having reflective and transmissive optical components positioned along a folded and segmented optical axis or path, one or more optical path extenders are provided for selected optical path segments that require operative path length adjustment so that an electromagnetic radiation beam, which traverses the folded optical path with selected information imparted into and detected from the beam, can be imaged upon a defined and maximum usable area or region both on the reflective components and on an end detector component.
