The breathing protection equipment includes a mask having an inflatable harness and a demand regulator with three operating modes which are manually selectable. The operating mode is indicated to the wearer of the mask by a repeater. The repeater has a mode sensor carried by the mask and a mode indicator located in the field of view of the wearer and driven by the mode sensor. The mode sensor may detect the position of the switch actuated by the user for changing the mode. The mode indicator may be a display on a mask storage box or on the mask.

An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
