The present invention relates to LED lamps suitable for forming automotive lighting systems, made of high power lambertian LEDs and a TIR collimator lens. In the present invention, a novel TIR collimator lens is developed to collect the light emitted from the LED source and through a pillow lens array; redistribution occurs to form a light pattern meeting ECE requirements.

The present invention relates to a method of automated process control operation wherein a physical object is directed into a read zone, information stored on an ID Container attached to the physical object is retrieved, physimetric property of the physical object is captured, the retrieved information is processed to provide recorded physimetric property specific to the physical object, the recorded physimetric property and captured physimetric property are passed to an analysis algorithm for comparison, and the results of the comparison are delivered to a controlling device. The results of the comparison will determine whether the physical property will continue to pass through the read zone or require to be rotated by the operator.
