At this time, the body-side CPU displays a warning, which informs that remaining battery is small, on an LCD. Although normally used to obtain temperature measurements, details in IR imagery result from emissivity variations as well as thermal variations. The feed screw is preferably driven by a closed-loop servo motor to achieve high-performance dispensing resolution.
