Abstract: A system (10) and method for killing ants in a subterranean colony (102) is disclosed. Liquid insecticide is vaporized in a fogging a vaporization chamber (23) by the exhaust of an internal combustion engine (14) such as that mounted on a lawn mower (12) or farm tractor. An insertion probe (30) having exhaust holes (36) is connected to an output of the vaporization chamber by a flexible hose (24). In operation, the probe is inserted into the subterranean colony (102), whereby vaporized insecticide is applied down in the colony. Such vaporized insecticide travels through passages to various "rooms" of the colony, thereby contacting ants in all parts of the colony.

Abstract: A teleradiology system capable of scanning X-ray images and the like and transmitting the scanned images to various locations is disclosed. The images may be compressed for storage or transmission. Compressed images can be transmitted much more quickly and take up much less space than uncompressed images. Compressed images can be expanded for, among other things, viewing. The compressor/expander and input/output devices reside on a bus structure in such a manner that digital image data can be selectively passed between the compressor/expander and the various input/output devices.

Abstract: A personal security device incorporated into a conventional flashlight for informing a person, by remote control means, who is outside the door of the house, and indicating by a picture, whether it is a man, woman or child, the picture appearing on a view screen of a unit mounted on the flashlight, so that a person is thus cautioned against opening the door, particularly if there is a man outside.
