Similar, contiguous primitives are stored as a single primitive in zone rendering bins. A camera is mounted on the headset. The output numerical value of differential production is added to the current production rate of the plants to obtain a new production rate which is applied during the forecast period. First and second field plates are respectively disposed in the first and second dielectric regions. The cryogenic vial allows for reduced processing time and minimizes the chance a sample may be lost or damaged while being processed. The software layer communicates in device under test terms whereas the hardware layer communicates in the terms of the testing apparatus.
