Abstract: The present invention relates to the packaging of commercial off-the-shelf (COTS) electronic modules and equipment for use in harsh military or commercial environments. The ruggedized container of this invention is a light-weight container weighing less than half of the weight of commercially available containers having similar functionalities and which is intended for use in similar harsh environments. The reduced weight and size of the ruggedized container of this invention are consistent with size and/or weight critical applications such as transport of portable flight line testers, submarines, space craft, air craft, and the like. The ruggedized container of this invention, comprises five major components: a transit case, a card cage, a vibration isolator assembly, cooling system, and power supply. Each element of the chassis is individually enhanced for size and weight.

Abstract: A method for imaging substances leaking from underground structures using continuous-wave signals includes translating an antenna array over the ground, transmitting a continuous-wave signal into the ground at an array of points, detecting the amplitude and phase of the reflected signal at each point, transforming the reflectance values into the frequency domain, propagating this reflectance spectrum to a predetermined depth, and transforming the propagated spectrum into an image in the spatial domain at that depth. An image representing the underground structure containing the substance may be overlayed on the calculated image to detect differences that represent leakage. Successive images of the same area may be produced over a period of time and the differences compared to determine the rate of leakage.

Abstract: A modular data link having a transmit processor for receiving input data and for providing different portions of the input data at each of a plurality of outputs. A plurality of transmit channels each receive an input data portion and transmit a signal corresponding to the received input data portion. An antenna collects the transmitted signals and provides an output thereof. A plurality of received channels each receive the collected signals from the antenna and extract a different input data portion from the collected signals. A receive processor having a plurality of input each coupled to a respective receive channels receives the extracted different input data portions so as to recombine the different input data portions in regenerating said original input data as output data.
