Abstract

A system for monitoring an overhead storage bin includes a proximity sensor, a load sensor, a latch mechanism sensor, and a controller operatively connected to the proximity sensor, the load sensor and the latch mechanism sensor. The controller is configured to retrieve proximity data from the proximity sensor indicative of a space status of an overhead storage bin, retrieve load data from the load sensor indicative of a stowage weight status of the bin, and retrieve a latch status from the latch mechanism indicative of a latch status of an access door of the bin. The controller is further configured to determine, based on the space status, the weight data, and the latch status, a probability indicative of whether an item stowed in the bin may fall from the bin, and output, based on the probability, an indication on an output device on an exterior surface of the bin.

First claim

The invention claimed is:

1. A system for monitoring an overhead storage bin comprising:
a proximity sensor, a load sensor, and a latch mechanism sensor; and
a controller operatively connected to the proximity sensor, the load sensor and the latch mechanism sensor, the controller configured to:
retrieve proximity data from the proximity sensor indicative of a space status of an overhead storage bin;
retrieve load data from the load sensor indicative of a stowage weight status of the overhead storage bin;
retrieve a latch status from the latch mechanism indicative of a latch status of an access door of the overhead storage bin;
determine, based on the space status, the weight data, and the latch status, a probability indicative of whether an item stowed in the overhead storage bin may fall from the bin;
output, based on the probability, an indication on an output device configured on an exterior surface of the overhead storage bin.

2. The system of claim 1 , wherein the controller is further configured to:
retrieve proximity data, weight data, and a latch status from a plurality of overhead storage bins connected to the controller;
determine, for each of the plurality of overhead storage bins, a hazard status indicative of whether an item stowed in the overhead storage bins may fall from the bin; and
output the hazard status for each of the plurality of overhead storage bins, on an output device of each of the plurality of overhead storage bins, wherein the hazard status is indicative of whether an item stowed in the respective overhead storage bin may fall from the bin.

3. The system of claim 2 , wherein the controller is further configured to output, to an operatively connected display device, data indicative of a space status, a load status, a latch status, and the fall indication for each of the plurality of overhead storage bins.

4. The system of claim 1 , wherein the proximity sensor is a sensor bank comprising a plurality of sensors configured to determine whether a stowed item is proximate to the access door.

5. The system of claim 1 , wherein the latch mechanism sensor comprises at least one sensor configured to determine whether the latch is in a fully latched position.

6. The system of claim 1 , wherein the load sensor comprises an array of load sensors configured on a base of the overhead storage bin.

7. The system of claim 6 , wherein the load data comprises a load distribution with respect to the array of load sensors.

8. The system of claim 7 , wherein the controller is configured to selectively output an indication of the load distribution for each of the plurality of overhead storage bins.

9. A computer-implemented method for monitoring an overhead storage bin comprising:
retrieving via a processor, proximity data from a proximity sensor indicative of a space status of an overhead storage bin;
retrieving, via the processor, load data from a load sensor indicative of a stowage weight status of the overhead storage bin;
retrieving, via the processor, a latch status from the latch mechanism indicative of a latch status of an access door of the overhead storage bin;
determining, via the processor, a probability indicative of whether an item stowed in the overhead storage bin may fall from the bin, the determination based on the space status, the weight data, and the latch status; and
outputting, based on the probability, an indication on an output device configured on an exterior surface of the overhead storage bin.

10. The method of claim 9 , further comprising:
retrieving, via the processor, proximity data, weight data, and latch status from a plurality of overhead storage bins connected to the controller;
determining, for each of the plurality of storage bins, a hazard status indicative of whether an item stowed in the overhead storage bins may fall from the bin; and
outputting the hazard status for each of the plurality of overhead storage bins, on an output device of each of the plurality of overhead storage bins, indicative of whether an item stowed in the respective overhead storage bin may fall from the bin.

11. The method of claim 10 , wherein the controller is further comprising outputting, to an operatively connected display device, data indicative of a space status, a load status, a latch status, and the fall indication for each of the plurality of overhead storage bins.

12. The method of claim 9 , wherein the proximity sensor is a sensor bank comprising a plurality of sensors configured to determine whether a stowed item is proximate to the access door.

13. The method of claim 9 , wherein the latch mechanism sensor comprises at least one sensor configured to determine whether the latch is in a fully latched position.

14. The system of claim 9 , wherein the load sensor comprises an array of load sensors configured on a base of the overhead storage bin.

15. The system of claim 14 , wherein the load data comprises a load distribution with respect to the array of load sensors.

16. The system of claim 15 , wherein the controller is configured to selectively output an indication of the load distribution for each of the plurality of overhead storage bins.

17. A non-transitory computer-readable storage medium storing executable instructions for performing a method for monitoring an overhead storage bin, the method comprising:
retrieving via a processor, proximity data from a proximity sensor indicative of a space status of an overhead storage bin;
retrieving, via the processor, load data from a load sensor indicative of a stowage weight of the overhead storage bin;
retrieving, via the processor, a latch status from the latch mechanism indicative of a latch status of an access door of the overhead storage bin;
determining, via the processor, a probability indicative of whether an item stowed in the overhead storage bin may fall from the bin, the determination based on the space status, the weight data, and the latch status; and
outputting, based on the probability, an indication on an output device configured on an exterior surface of the overhead storage bin.

18. The non-transitory computer-readable storage medium of claim 17 , further comprising:
retrieving, via the processor, proximity data, weight data, and latch status from a plurality of storage bins connected to the controller;
determining, for each of the plurality of storage bins, a hazard status indicative of whether an item stowed in the overhead storage bins may fall from the bin; and
outputting the hazard status for each of the plurality of overhead storage bins, on an output device of each of the plurality of overhead storage bins, indicative of whether an item stowed in the respective overhead storage bin may fall from the bin.

19. The non-transitory computer-readable storage medium of 18 , further comprising outputting, to an operatively connected display device, data indicative of a space status, a load status, a latch status, and the fall indication for each of the plurality of overhead storage bins.
