The usage of digital cameras as luminance meters
Many luminance measuring tasks require a luminance distribution of the total viewing field. The approach of imageresolving luminance measurement, which could benefit from the continual development of position-resolving radiation detectors, represents a simplification of such measuring tasks. Luminance measure cameras already exist which are specially manufactured for measuring tasks with very h...
متن کاملDrug Usage in Pilots Involved in Aviation Accidents Compared With Drug Usage in the General Population: From 1990 to 2005
Civil aviation pilots represent a small subsection of the general population. Therefore, one might expect to see the same types of drugs used by pilots that are found in the general population. The purpose of this study was to compare usage of both illegal drugs and abused prescription medications in pilots involved in civil aviation accidents from 1990 to 2005 with that of the general populati...
متن کاملUltrasonic Sensing for Water Flow Meters and Heat Meters
Ultrasonic flow meters are gaining wide usage in commercial, industrial and medical applications. Major benefits of utilizing this type of flowmeter are higher accuracy, low maintenance (no moving parts), noninvasive flow measurement, and the ability to regularly diagnose health of the meter. This application note is intended as an introduction to ultrasonic time-of-flight (TOF) flow sensing us...
