The Rolleiflex SLX is a line of medium format single lens reflex cameras made by Rollei, in regular production starting from 1976.The SLX incorporated electronic autoexposure and motorized film transport, competing directly with the integrated-motor Hasselblad 500EL/M and effectively displacing the earlier Rolleiflex SL66 line, although the older camera continued to be produced.
The first example of electronic countermeasures being applied in a combat situation took place during the Russo-Japanese war.On July 13, 1904, Russian wireless telegraphy stations installed in the Port Arthur fortress and on board Russian light cruisers successfully interrupted wireless communication between a group of Japanese battleships.
An officer programs a JPADS bundle with drop coordinates in preparation for a resupply mission.

The stereoplotter serves an important need of allowing aerial photos to become the base for contours and elevation maps. In the United States the largest use of topographic maps is the United States Geological Survey (USGS). The USGS has cataloged all of the territory of the United States and has produced topographic sheets for all of it.
Anti-aircraft warfare is the counter to aerial warfare [1] and includes "all measures designed to nullify or reduce the effectiveness of hostile air action". [2] It encompasses surface-based, subsurface (submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons).
An aerial tramway consists of one or two fixed cables (called track cables), one loop of cable (called a haulage rope), and one or two passenger or cargo cabins.The fixed cables provide support for the cabins while the haulage rope, by means of a grip, is solidly connected to the truck (the wheel set that rolls on the track cables).
