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.

Abstract: A respirator includes a frame, a filter layer, and a face seal member. The frame has an outer side and an inner side. The frame defines an opening therethrough. The filter layer is mounted to the outer side of the frame and covers the opening of the frame. The filter layer is configured to prohibit permeation of aerosol, gas, and/or vapor contaminants therethrough. The face seal member is mounted to the inner side of the frame. The face seal member includes a seal contact area configured to engage a facial surface of a wearer. The face seal member incorporates a phase change material therein. The phase change material is configured to provide localized cooling by absorbing heat emitted by the wearer.

Abstract: A filter mask includes an oronasal cup, an inhalation directional cover, and an exhalation diverter body. The oronasal cup encloses a nose and mouth of a user. The oronasal cup is fluidly coupled with a filter. The inhalation directional cover is configured to be joined to the filter. The inhalation directional cover includes an elongated wing portion that is oriented in an inhalation direction that is angled with respect to the center axis of the filter. The exhalation diverter body is fluidly coupled with the oronasal cup. The exhalation diverter body defines an exhalation duct that directs exhaled air out of the oronasal cup along an exhalation direction. The inhalation direction and the exhalation direction are oriented away from a plane of interaction between the user and another person.
