摘要： A personal breathing system incorporating a phased-dilution demand oxygen regulator (PDDOR) includes a pressurized oxygen source and oronasal mask, a dilution valve for supplying ambient air and a demand valve for supplying pure oxygen. The PDDOR senses the mask pressure associated with the start of an inhalation cycle, maintaining pressure to the demand valve through an initial demand phase during which 100% pure oxygen is supplied through the demand valve. Control pressure within the PDDOR drops throughout the initial demand phase; when the pressure drops below a lower threshold the PDDOR main valve is closed, blocking the demand valve and cutting off the oxygen supply. Ambient air is provided to the mask via a dilution valve to preserve flow to the user.

摘要： A respiratory mask system is presented. This respiratory mask system includes an inflatable harness and a bone conduction device to provide audio to a user while wearing the respiratory mask system. The bone conduction device is installed on or interconnected with a portion of the inflatable harness, such as a tube of the inflatable harness that is positioned at least somewhat in proximate to a user's ear. Inflation of the inflatable harness may press the bone conduction device against the user to enhance the delivery of audio to the user.

摘要： The emergency oxygen supply for passengers in an aircraft comprises an oxygen source with a number of pulse breathing masks which are conductively connected to the oxygen source, wherein an individual shut-off valve which in the non-actuated condition is switched to block is provided in each conduit to a breathing mask. The emergency oxygen supply moreover comprises an impulse breathing control for actuating each individual shut-off valve, as well as an auxiliary conduit which connects the oxygen source to the breathing masks whilst bypassing the individual shut-off valves and which in each case via a check valve is connected to the respective conduit which leads to the breathing mask, or to the breathing mask itself. The auxiliary conduit is connected to the oxygen source via a central shut-off valve which is switched to open in the non-actuated condition.

摘要： A method for controlling the pressure and/or the flow rate of a fluid includes withdrawing flow energy from a fluid flowing through a pipeline (15). This energy is converted at least partially into electrical energy and used for the electrical control (65) of the flow rate and/or the pressure of a fluid. The device for controlling the flow rate and/or pressure of a fluid in a pipeline (20) has at least one electric generator (35), which is developed for the withdrawal of flow energy from a flowing fluid and for converting this energy at least partially into electrical energy. The device has a control mechanism (65) for controlling the flow rate and/or pressure of a fluid in a pipeline (20) with an electric driving mechanism supplied by the generator (35).

摘要： An aircraft emergency oxygen supply system comprises a passenger oxygen mask for supplying oxygen to a passenger wearing the passenger oxygen mask; an oxygen source for supplying oxygen to the passenger oxygen mask; a breath sensor for detecting breaths of the passenger wearing the passenger oxygen mask; and a controller for controlling the supply of oxygen from the oxygen source to the passenger oxygen mask. The controller is configured for operating in a normal breathing mode, which includes supplying a normal breathing amount of oxygen (VN) from the oxygen source to the passenger oxygen mask at every breath of the passenger wearing the passenger oxygen mask; deriving a breathing frequency indicator from a plurality of successive breaths of the passenger; and switching into a fast or into a low breathing mode if the breathing frequency indicator indicates a breathing frequency above or below predefined frequency thresholds.

摘要： A passenger oxygen mask for use in an aircraft comprises a face piece defining a breathing space and having a proximal end, which is to be placed on the face of a user, and an opposite distal end; and a valve plate arranged at the distal end of the face piece. The valve plate is equipped with an oxygen port for an inflow of oxygen from an oxygen source into the breathing space; and an inlet valve for an inflow of ambient air into the breathing space. The valve plate has an elongated shape, having a longitudinal dimension in a longitudinal direction (L) and a transverse dimension, which is smaller than the longitudinal dimension, in a transverse direction (T).
