Abstract
Disclosed herein is an in-mask display or feedback system having a lens coupled to a face blank of the mask, the lens covering a facepiece. The feedback system includes a display apparatus coupled to the facepiece, and disposed within an interior of the mask, the display apparatus being powered by a first power source coupled to a housing of the display apparatus. The feedback system further includes a recording device (e.g., a camera) coupled to the face blank, the recording device operable to communicate data (e.g., wirelessly or wired) with the display apparatus. In some approaches, the recording device is powered by a second power source. In other approaches, the first power source provides power to both the recording device and the display apparatus. In another approach, the display apparatus includes an adjustment aperture formed therethrough to allow adjustment of an eye piece housing a display.
