"These people are SICK"?
Probably nothing but found this:
SICK AG Sensor Intelligence
Sick AG (or SICK, as spelled by the company), based in Waldkirch (Breisgau), Germany, is a global manufacturer of sensors and sensor solutions for industrial applications. The company is active in the areas of factory and logistics automation and process automation.
The company is particularly well known for its laser scanners, which are used as sensors in the fields of facility protection (security), ports and robotics. Five LIDARs produced by the Sick AG were used for short-range detection on Stanley, the autonomous car that won the 2005 DARPA Grand Challenge; they can be seen on the roof of the vehicle. SICK/IBEO LIDARs were also used for obstacle avoidance, mapping and pedestrian tracking on WAMbot, the autonomous vehicle that came 4th in the MAGIC 2010 competition.
Sick AG was founded in 1946 by Erwin Sick (1909-1988); he had received a license from the then US-managed local government to operate his engineering firm.
The company’s product portfolio includes photoelectric sensors, light grids, inductive, capacitive and magnetic sensors, opto-electronic protective devices, vision sensors, detection, ranging and identification solutions such as bar code scanners and RFID readers, analyzers for gas and liquid analysis as well as gas flow measuring devices.
