We have used an infrared camera (Inframetrics
		    model 600L) to take pictures of the portables to examine                         "hot" and "cool" areas
		    of the portables. Infrared cameras function by utilizing long wave
		    radiation to form a colored "image" of an object. In the photographs,
		    the light colors are the hottest area while the dark colors are the
		    coldest (i.e. white was the hottest, black was the coldest). Select
		    from the bulleted list below to see the infrared photos.
