Abstract: Full facemask including a face seal configured to directly engage a face of an individual. The face seal defines a lens opening. The full facemask also includes a mask lens that is coupled to the face seal and disposed within the lens opening. The mask lens has a passage edge that defines a cartridge passage through the mask lens. The full facemask also includes a cartridge module having at least one of a filter or an air regulator. The cartridge module is disposed within the cartridge passage and circumscribed by the passage edge of the mask lens. The full facemask also includes a locking member that includes a first member surface that directly engages the mask lens and a second member surface that directly engages the cartridge module. The locking member secures the mask lens and the cartridge module in fixed positions with respect to each other.

Abstract: According to various embodiments, a case for a portable electronic device (PED) includes a stand that is configured to support a PED in an upright position. The stand may be pivotally coupled to a sliding member that can move along the case's back side. The sliding member and stand may move between a first position in which the stand supports the device in an upright position and a second position in which the stand lies flush with the rear face. Thus, the stand may selectively support the case in an upright position or be compact for easy storage.
