Abstract: A method of making an electrical connection with a cluster of separate electrical conductors wherein each of the electrical conductors are frayed at its end exposing a center wire and a ground shield. The cable is mounted within a cable housing. The center wire of each electrical conductor is attached to a separate female center conductor. The cable housing is interconnected with a connector body which includes the female center conductors. The connector body also includes ground contacts which connect with the ground shields to achieve a grounding electrical connection from the cable housing through the connector body.

Abstract: The subject invention is an electrical connector for a pair of printed circuit boards which utilizes a vertical pin header connected to one printed circuit board and a right angle receptacle connected to the other printed circuit board. The printed circuit boards are to be connected together by the electrical connector in a right angle relationship with one printed circuit board being located edgewise to the other printed circuit board. A mass of separate positive circuit paths is obtained from one printed circuit board to the other with the distance between contacts which form these circuit paths to be approximately two millimeters. The vertical pin header and the right angle receptacle are fixedly mounted on their respective printed circuit boards without the use of solder. The right angle receptacle matingly connects with the vertical pin header in only one position.

Abstract: A three-color camouflage system comprises layers of camouflage material hng low, intermediate and high thermal emissivities in the infrared spectral range, and appearing black, green and brown in the visible spectral range. The camouflage surface is structured in such manner that there is color adaptation to the natural background in the visible spectral range, as well as adaptation to the natural background in thermal emissivity in the infrared spectral range so that targets cannot be recognized with infrared sensing devices. Thermal emissivity in the infrared spectral range is controlled by superimposing layers of intermediate and high emissivity onto a basic low emissivity camouflage layer and providing perforations in these layers allowing the low-emissivity layer to be seen. High-emissivity areas are provided by perforations allowing the high-emissivity surface of the object being camouflaged to be seen.

Abstract: The emissivity of camouflage material is determined from the apparent body emperature measured by a radiometer, calibrated to indicate a temperature of a blackbody would emit corresponding to the radiation received therefrom; and the true temperature of the material and the true temperature at an infrared detector of the radiometer of a radiometer. Computation means is provided for calculating emissivity from the so measured temperatures and for displaying the result.
