A road weather information system (RWIS) is a combination of technologies that collect, transmit, model, and disseminate weather and road condition information. The component of an RWIS that collects weather data is the environmental sensor station (ESS). An ESS is a suite of sensors that collect and transmit pavement and meteorological data.
Spot welding. Resistance spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets together.
