Welding shield with exposure detection for precautionary welding hazard avoidance

摘要

Head mounted device 2010; At least one position sensor coupled to the head mounted device; At least one optical filtering shield (2012) coupled to at least one position sensor; At least one photodetector (2019); And receiving, from the photodetector, an indication that the intensity of light detected by the photodetector exceeds an exposure threshold; Determine from the at least one position sensor that the light filtering shield is not located in the face of the operator to filter out light having an intensity exceeding the exposure threshold; At least one computing device configured to generate an indication for output in response to determining that the optical filtering shield is not located in the face of an operator wearing a head mounted device to filter light having an intensity exceeding an exposure threshold 2017). / RTI
