Definitions

  • Embodiments may relate generally to devices and/or methods for displaying information to a user wearing a mask, such as a SCBA mask.
  • HUD heads-up display
  • the HUD display unit usually may be fitted rather loosely to an interior element of the mask, resulting in a HUD that may not be steady (complicating reading of the HUD by the user) and may even come free within the mask during fierce movements (which could pose a safety risk to the user) .
  • the internal HUD unit would, along with its separate battery, occupy significant space within the already limited space inside the mask. This may cause fit, comfort, and breathability issues for using the mask with such a conventional internal HUD unit.
  • the internally mounted HUD unit often may block some portion of the user’s view through the viewing port of the mask, thereby restricting field of view for the mask. Since such masks are typically used in emergency situations, ensuring adequate field of view can be an important safety issue. Furthermore, an internal HUD unit may be rather difficult for a user to properly observe, given the angle and small distance from the user’s /wearer’s eye. Disclosed embodiments relate to a frame integrated information display indicator, which may address one or more of these issues. Accordingly, disclosed embodiments may allow for improved masks, such as SCBA masks, with capabilities to better display information to the wearer of the mask.

Abstract

La présente invention concerne de manière générale, dans des modes de réalisation, des dispositifs indicateurs d'affichage d'informations du type qui pourrait être utilisé avec un masque, tel qu'un appareil respiratoire autonome, comportant un orifice de visualisation transparent. Par exemple, de tels modes de réalisation d'indicateur d'affichage pourraient typiquement être intégrés dans le cadre de l'orifice de visualisation du masque, de façon à se trouver autour de la périphérie externe de l'orifice de visualisation. En outre, dans certains modes de réalisation au moins un des indicateurs d'affichage peut avoir deux faces, une face inclinée vers l'intérieur et une face inclinée vers l'extérieur. En ayant deux faces pour de tels indicateurs, tant l'utilisateur qu'un membre externe de l'équipe pourraient être informés simultanément par l'indicateur.
