Abstract: A system and apparatus for detecting and evaluating surface conditions on a road surface and atmospheric conditions simultaneously from a vehicle is disclosed. The system comprises a sensor for detecting the presence of deposited material on a road surface, a detector for determining one or more characteristics of the deposited material such as freezing temperature, process means for converting a detected signal and display means for displaying the condition of the road surface, and a sensor for detecting falling precipitation. An embodiment of the present invention includes a remote sensing apparatus which utilizes electromagnetic radiation to sense actual surface material conditions, temperatures, and composition and local atmospheric conditions at the vehicle as it is moving over a travel surface. This information is then processed through a computer in order to determine those additional steps necessary to apply additional materials to the road surface in order to minimize hazardous driving conditions.

Abstract: A method and apparatus for forming annularly-corrugated tubes and cables utilizing a multiple gear corrugating head which is rotated about the tube or cable, to be corrugated as the tube or cable is drawn through the head. Two or more of the gears each have a different prime number of gear teeth which form the corrugation. A radio-frequency cable formed by the invention exhibit greater consistency and quality than cables produced by conventional corrugating gear heads, and in particular, show improved VSWR characteristics

Abstract: A wire twisting machine and method provide a randomly varying lay to pairs of twisted wires forming a cable. A pair of wires are fed into a motor driven bow mechanism which twists the wires at a given rate of speed. The bow winding speed is sensed to provide a signal to a control system employing a computer which generates a randomly varying signal between a selected minimum and maximum range. The random signal is applied to an oscillator which provides a varying frequency signal to a power supply unit. A pulsed direct voltage signal then controls a stepping motor which applies the randomly varying lay signal to vary the speed of the capstan winding the wires with respect to the independent bow speed. This varies the length of lay of the twisted wires within controlled limits.
