The lab's nominees are: the eValuator-3500, an integrated circuit device used in medical imaging; CZT-ElectrodePlus, a nonmetallic electrode contact used to fabricate radiation detectors; the Active Superconducting Fault Current Limited, which protects grid equipment from short circuits, and the Binary Pseudo-Random Calibration Tool, used in surface imaging.
