Fog can inhibit the driver's vision and has been among the highest heating, ventilating, and air conditioning (HVAC) complaints reported in recent J. D. Power Initial Quality Surveys. An automatic fog control system which uses the inputs from a unit such as Delphi's Integrated Dew Point and Glass Temperature (IDGT) sensor operates in conjunction with the automatic climate control system to prevent fogging. Unlike an infrared fog detector, the IDGT measures glass temperature, air temperature under the sensor, and the relative humidity of the air to react prior to fog occurring. Recent enhancements in the sensor include improved response for the capacitive humidity sensor in the 80 to 100 percent relative humidity range and more accurate (2 percent) thermistors to measure the fogging condition more accurately.

Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Weaned on the relatively effortless connectivity of today’s massive variety of consumer electronic products, automation users in the IIoT will likely not tolerate too many competing, piecemeal standards for long. And the Industrial Internet Consortium is trying to preempt history.
