“PARAGON” MEANS “SAMPLE”

This name was chosen in 1988 by Klaus D. Frers for his future company: its products were to become role models.

The idea was a success: Paragon was the first among suppliers of electronic components to certify its products according to the most stringent ISO 9002 standard, and then according to automobile standards QS 9000 and VDA 6.1. For our readers, the most interesting will probably be not the “struggle for quality”, but technical innovations that have already appeared (or are about to appear) in automobiles thanks to the engineers of the company. So, we present three samples from Paragon.

TO BETTER BETTER

Air conditioning systems can operate in two modes: full recirculation, when the air from the passenger compartment is repeatedly driven through the air conditioner, and with fresh air ventilation, which allows fresh air from the street. But is it fresh? When a huge truck smokes nearby, you have to urgently close the windows and the air intake flap so as not to suffocate. And sometimes the mood is spoiled by unpleasant (albeit harmless) aromas from fields and poultry farms sweeping outside the window. Here for all these (and some other) cases, AQS sensors from Paragon will come in handy. These boxes weighing 11 to 32 g are able to analyze the composition of the incoming air for the content of carbon monoxide (CO), benzene, gasoline, hexane, heptane, octane, nitrogen oxides (NOx), sulfur dioxide, hydrogen sulfide, carbon disulfide …

A miniature "laboratory" first determines the basic level of the content of these substances and reacts only to sharp emissions of concentration. And they, by the way, are not so rare. For example, at the entrance to the tunnel, the CO content can increase … 10, 000 times! Having registered a rapid increase in the concentration of “harmful substances”, the sensor will command to close the air intake flap (and if necessary, raise the windows and close the upper hatch) and switch the air conditioner to full recirculation mode. For those who use an armored vehicle, Paragon offers an additional sensor for tear and nerve gas.

CHANGING AIR QUALITY ON THE ROUTE

TO BETTER TO SEE

As soon as the air temperature on the street begins to drop, motorists are tormented: the windows are fogging. It is worth gape with the inclusion of blowing or incorrectly choose the ventilation mode, as the windshield rapidly becomes cloudy. I have to grab a rag. But this is if the car is not equipped with a SUC (Steam Up Control) sensor that detects the formation of condensate even in the bud and automatically turns on the desired mode for blowing the windshield.

A small (15 mm2) chip sticks to the glass and begins to fog at the same time. (By the way, achieving this simultaneity was the greatest difficulty for the developers.) Moisture particles, getting into the field of two-dimensional (flat) capacitors, change the dielectric constant and, therefore, the capacitance value. Moreover, this happens when 3-4 ° C remains to the dew point and the glass is still completely transparent. According to the principle “it is easier to prevent than to eliminate” the fan is turned on in advance. At the same time, the surface of the sensor begins to heat up and moisture, which has time to condense, immediately evaporates. The sensor is now ready for the next measurement cycle. And so for … 10 years! Such a resource is defined by the manufacturer. If we add that the SUC sensor distinguishes the rate of moisture condensation and reacts to its value by changing the blowing mode, it becomes clear: in this eighteen-gram product high technical achievements are concentrated.
