Preh Defogging Sensor (http://rbi.ims.ca/4927-545). Detecting window fogging in vehicles before the occurrence of visible condensation requires humidity and temperature sensors, as well as computer calculations. Mounted on the interior of the vehicle’s windshield, the humidity-sensitive element measures the relative humidity directly on the windshield. Using infrared technology, the sensor detects windshield fogging before it becomes visible to the human eye. A Negative Temperature Coefficient (NTC) thermistor reads the windshield temperature. With the data from the sensor the vehicle’s heating, ventilating and air conditioning system provides an optimal vehicle environment that takes into account humidity, as well as temperature.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicle’s parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but that’s just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
