Abstract

A container for an oxygen supply unit is described. The container may have a container well, wherein a container door can be pivotably joined at a container well's edge, wherein the container is provided with a sensor system, adapted to indicate a status and/or change of status of the door, in particular relative to the well. A system of an arrangement of a number of oxygen supply devices in a ceiling-panel along an aircraft cabin, in particular along an aircraft cabin alley of seats, also is described, wherein each oxygen supply unit is stored in a container.

First claim

The invention claimed is:

1. A container for an oxygen supply unit, comprising:
a. a well (i) having an edge region and (ii) configured in use to receive at least a portion of the oxygen supply unit;
b. a movable door (i) connected to the edge region of the well and (ii) configured to move between a first state, in which the door closes the well, a second state, in which the door is fully open relative to the well, and a third state in which the door is partly open relative to the well; and
c. means, comprising a sensor system, for detecting a state of the door from among the first, second, and third states.

2. A container according to claim 1 in which the sensor system comprises:
a. means, comprising an opening switch, for detecting whether the door is in the first state; and
b. means, comprising a motion sensor, for detecting whether the door is in the second or third state.

3. A container according to claim 2 in which the sensor system detects the third state by determining that (a) the opening switch fails to detect that the door is in the first state and (b) the motion sensor detects movement of the door relative to the well.

4. A container according to claim 3 in which the sensor system detects the second state by determining that (a) the opening switch fails to detect that the door is in the first state and (b) the motion sensor fails to detect movement of the door relative to the well.

5. A container according to claim 4 in which the sensor system detects the first state by determining that (a) the opening switch fails to detect any gap between the door and the well and (b) the motion sensor fails to detect movement of the door relative to the well.

6. A container according to claim 5 (a) further comprising the oxygen supply unit and (b) in which oxygen supply unit comprises at least one of an oxygen pressure cylinder or a chemical oxygen generator positioned at least partly in the well.

7. A container according to claim 1 in which the door is pivotally connected to the edge region of the well.

8. A container according to claim 1 in which the sensor system comprises a three-axis acceleration sensor.

9. A container according to claim 1 further comprising means for harvesting energy.

10. A container according to claim 9 in which (i) each of the well and door has exterior surfaces and (ii) the energy-harvesting means comprises a solar cell panel attached to at least one of the exterior surfaces of the well or door.

11. A method of monitoring a container for an oxygen supply unit, the container including a well having an edge region to which a moveable door is connected, the method comprising:
a. detecting, using detecting means comprising a sensor system, a state of the door from among a first state, in which the door closes the well, a second state, in which the door is fully open relative to the well, and a third state in which the door is partly open relative to the well; and
c. monitoring the detected state of the door.

12. A container for an oxygen supply unit, comprising:
a. a well (i) having an edge region and (ii) configured in use to receive at least a portion of the oxygen supply unit;
b. a movable door (i) connected to the edge region of the well and (ii) configured to move between a first state, in which the door closes the well, a second state, in which the door is fully open relative to the well, and a third state in which the door is partly open relative to the well; and
c. a sensor system comprising: (i) means, comprising an opening switch, for detecting whether the door is in the first state; (ii) means, comprising a motion sensor, for detecting whether the door is in the second or third state; and (iii) means, comprising a status sensor, for detecting whether the door is in the third state.
