## Background
BACKGROUND
This application claims priority to Indian Patent Application No. 3865/DEL/2015 filed Nov. 26, 2015, the entire contents of which is incorporated herein by reference.
Stowing carry-on items on the overhead bin of an aircraft may be limited by bin space and the size of typical carry-on luggage. Although most airlines limit the number of bags that can be stowed in the bins, some passengers may carry more carry-on items than the allowed. Since carry-on luggage may vary in size, some passengers having over-sized luggage may take more bin space than others. Moreover, bags may be stored on a first come first serve basis, so the passengers boarding in the later (last) boarding group may not have enough space to store their bags in the overhead bin simply because of the order of their boarding the aircraft.
In other instances, passengers may need to check their luggage because other passengers have fit oversized bags in the overhead bin, which may requires later-boarding passengers to check their permissibly-sized luggage with the flight attendant and retrieve their luggage at the arrival gate or the baggage claim.
Flight attendants may not have a complete picture of space availability in all the overhead bins, and may not be aware that a single passenger has taken more than their allotted space in the bin. Flight attendants may open every individual overhead bin in an effort to assist passengers boarding later, to search for space availability to stow their carry-on bags. Pilots and airlines may be affected by the delay take-off.
Some passengers may attempt to fit the over-sized and/or overweight luggage in the overhead bins using force to close the door. This may cause structural damage to the overhead bins, which may also result in delayed takeoff or a cancelled flight if the structural damage is significant. In other instances, if a bin door is improperly closed and it is not noticed by a flight attendant, it may be possible for the overhead bin door latch mechanism to open during the flight, which may allow items to fall from the storage bin. It may not be clear to a flight attendant that a bin door is improperly closed, is overloaded, or remains unlocked or is improperly closed. Moreover, using conventional methods, it may not be feasible for a flight attendant to inspect and monitor the status of all overhead storage bins on the aircraft.
BRIEF DESCRIPTION
In some embodiments, a system for monitoring an overhead storage bin may include 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 may be 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, and retrieve a latch status from the latch mechanism indicative of a latch status of an access door of the overhead storage bin. The controller may be 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 overhead storage bin may fall from the bin, and output, based on the probability, an indication on an output device configured on an exterior surface of the overhead storage bin.
In other embodiments, a computer-implemented method for monitoring an overhead storage bin may include 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, and 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. The method may further include determining, via the processor, a probability indicative of whether an item stowed in the overhead storage bin may fall from the bin. In some embodiments the determination may be based on the space status, the weight data, and the latch status. The method may further include outputting, based on the probability, an indication on an output device configured on an exterior surface of the overhead storage bin.
In yet other embodiments, a non-transitory computer-readable storage medium may store executable instructions for performing a method for monitoring an overhead storage bin. The method may include 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, and 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. The method may further include determining, via the processor, a probability indicative of whether an item stowed in the overhead storage bin may fall from the bin. In some embodiments the determination may be based on the space status, the weight data, and the latch status. The method may further include outputting, based on the probability, an indication on an output device configured on an exterior surface of the overhead storage bin.

Moreover, memory 102 may incorporate electronic, magnetic, optical, and/or other types of non-transitory computer-readable storage media. Note that the memory 102 can have a distributed architecture, where various components are situated remote from one another, but can be accessed by the processor 101.
The instructions in memory 102 may include one or more separate programs, each of which comprises an ordered listing of computer-executable instructions for implementing logical functions. In the example of FIG. 1, the instructions in memory 102 may include a suitable operating system 111. Operating system 111 can control the execution of other computer programs and provides scheduling, input-output control, file and data management, memory management, and communication control and related services.
Input/output adaptor 103 can be, for example but not limited to, one or more buses or other wired or wireless connections, as is known in the art. The input/output adaptor 103 may have additional elements, which are omitted for simplicity, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.
Interface adaptor 112 may be configured to operatively connect one or more I/O devices to computer 100. For example, interface adaptor 112 may connect a conventional keyboard 109 and mouse 110. Other output devices, e.g., speaker 113 may be operatively connected to interface adaptor 112. Other output devices may also be included, although not shown.

Network 115 can be an IP-based network for communication between computer 100 and any external device. Network 115 may transmit and receive data between computer 100 and devices and/or systems external to computer 100. In an exemplary embodiment, network 115 can be a managed IP network administered by a service provider. Network 115 may be a network internal to an aircraft, such as, for example, an avionics network, etc. Network 115 may be implemented in a wireless fashion, e.g., using wireless protocols and technologies, such as WiFi, WiMax, etc. Network 115 may also be a wired network, e.g., an Ethernet network, an ARINC 429 network, a CAN, etc., having any wired connectivity including, e.g., an RS232 connection, RS422 connection, etc. Network 115 can also be a packet-switched network such as a local area network, wide area network, metropolitan area network, Internet network, or other similar type of network environment.

If computer 100 is a PC, workstation, laptop, tablet computer and/or the like, the instructions in the memory 102 may further include a basic input output system (BIOS) (omitted for simplicity). The BIOS is a set of essential routines that initialize and test hardware at startup, start operating system 111, and support the transfer of data among the operatively connected hardware devices. The BIOS is stored in ROM 108 so that the BIOS can be executed when computer 100 is activated. When computer 100 is in operation, processor 101 may be configured to execute instructions stored within the memory 102, to communicate data to and from the memory 102, and to generally control operations of the computer 100 pursuant to the instructions.

Each of sensors 301-304 may include a single sensor or a bank of sensors, such as a sensor array. In some embodiments, sensors 202 may include a plurality of sensors configured to provide information indicative of a position of an object, movement of an object, weight of an object, information indicative of whether an overhead storage bin door is open, whether overhead storage bin 201 is overloaded, under-loaded, and/or data useful for making other determinations.
Load sensor 303 may include a plurality of load sensors configured in an array (as depicted with respect to FIG. 7) and may be configured to determine a weight and relative weight distribution with respect to the array of load sensors. In other aspects, proximity sensor 302 may include a plurality of proximity sensors (as depicted with respect to FIGS. 5-6) and may be configured to determine the proximity of an object stored inside of overhead storage bin 201. Lock sensor 301, as depicted in FIG. 7, may include a plurality of sensors configured to determine an actuation state of one or more locks, latches, etc. For example, if a lock or latch is operative and configured correctly (e.g., latched and/or locked), lock sensor may determine the operative state of the lock and/or latch. In some aspects, microcontroller may provide a lock and/or unlock command to lock censor 301.
Output device 203 may include an output device 203 configured to output a status for each of the plurality of sensors 202. For example, output device 203 may include a space status output 305, a weight status output 306, a latch status output 307, and a fall probability indicator 308. For example, in some aspects, microcontroller 204 may determine, based on sensor information retrieved from light sensor 304 and/or proximity sensor 302, whether there is available storage space in overhead storage bin 201. Microcontroller 204 may output a status of available space for stowage inside of overhead storage bin 201.
Microcontroller 204 may determine, based on sensor information received from load sensor 303, a stowage weight status that may indicate whether overhead storage bin 201 is under loaded, overloaded, etc. A weight status output 306 may receive data from microcontroller 204 and indicate a stowage weight status of overhead storage bin 201.
Latch status output 307 may indicate whether a lock or latch of overhead storage bin 201 is in a safe and/or operative position. The output status for all outputs 305-308 may be output via one or more lights, e.g., indicator lights 305a, 306a, 307a, and 308a. Microcontroller 204 may indicate an output status via other means not shown, such as, for example, a digital display, an output speaker, and/or an audible alarm, etc.
Weight status output 306 may be indicative of a stowage weight status of overhead storage bin 201. For example, microcontroller 204 may retrieve load sensor data from load sensor 303 indicative of a weight of one or more items stowed in overhead storage bin 201. Microcontroller 204 may determine a stowage weight status of overhead storage bin 201 based on the data, and output an indication of the status via weight status output 306. Microcontroller 204 may output the status via indicator lights 306a. A weight status may be indicative of overloading or under-loading of overhead storage bin 201.
Latch status output 307 may be configured to output a safety status of an access door of overhead storage bin 201. For example, microcontroller 204 may access lock sensor 301, determine whether the latch and/or lock is in a safe position with respect to the travel of the aircraft (e.g., the aircraft is preparing for takeoff, in flight, preparing for a landing, etc.), and output the status via lock status output 307.
Fall probability indicator 308 may indicate whether an item stowed in overhead stowage bin 201 has a high probability of falling out of the bin. For example, microcontroller 204 may access proximity sensor 302, lock sensor, 301, load sensor 303, and light sensor 304, determine, based on the information from sensors 301-304 whether an item stowed in overhead storage bin 201 may fall, and output the indication via output indicator lights 308a. 
All of indicator lights 305a-308a may be configured with a plurality of colors, each of which indicating a relative strength of the warning, probability, etc. For example, a red light may indicate a strong warning status, a yellow may indicate a medium status, and a green light may indicate a safe or operative status.
Referring now to FIG. 4, an overhead storage bin 201 is depicted having a plurality of light sensors 304, in accordance with some embodiments. Light sensors 304 and light sources 305 may be configured on the inner wall of overhead storage bin 201. In some embodiments, one or more light sensors 304 and a one or more light sources 305 may be arranged in a straight line between source 305 and sensor 304 such that that a light beam 306 from light source 305 may be sensed by the one or more light sensors 304. In case any objects from the overhead storage bin 201 rests on access door 501 due to disturbance then the light beam from the light source 305 is obstructed by the object and no light beam is sensed by the light sensor 304. In some aspects, microcontroller 204 may convolute the light obstruction data along with weight information and weight distribution to determine the probability of items falling from the bin.
In other aspects, overhead storage bin 201 may include one or more light sensors 304 that may be configured to determine movement, proximity and/or position of items stored in overhead storage bin 201. For example, light sensors 304 may provide information indicative of a disturbance in the stowage during the flight which might in a higher probability of items falling from overhead storage bin 201. Microcontroller 204 may 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. Microcontroller 204 may output an alert to alert the passenger to open the bin door with care. In some embodiments, microcontroller 204 may also output an alert status in another display, such as, for example inflight entertainment (IFE) system 208. In some aspects, a displayed message may alert passengers seated below the particular overhead bin to fix the items in the overhead bin before items fall from the bin.
Light sensors 304 may be configured on the inner wall of overhead storage bin 201. Light sensors 304 may be arranged in a linear arrangement (having a light source 305 aligned linearly with a light sensor 304), which may be used to determine a probability of an item falling from overhead storage bin 201.
FIG. 5 depicts overhead storage bin 201 having a plurality of proximity sensors 302 configured to determine a space status of overhead storage bin 201. Sensors 302 may be further configured to provide information indicative of position of an item. Positional information may be indicative of whether an item stowed in overhead storage bin 201 may fall from the bin.
Although FIG. 5 depicts sensors 302 configured on an access door 501 of overhead storage bin 201, it is appreciated that sensors 302 may be configured in a number of different ways in order to determine positional and proximity information of items in overhead storage bin 201. For example, FIG. 6 depicts overhead storage bin 201 having proximity sensors 302 configured on a back surface of overhead storage bin 201 for sensing space availability and for sensing unsafe shifting of contents.
As depicted in FIG. 7, overhead storage bin 201 may include an access door 501 that may be opened and closed via a latch and/or lock. Overhead storage bin 201 may also include one or more load sensors 303 configured for determining position and weight of objects, and one or more latch/lock sensors 301 configured for determining whether the latch and/or lock of overhead storage bin 201 are safely configured. Load sensors 303 may be configured as a single sensor or a plurality of sensors distributed across the bottom of overhead storage bin 201. Latch/lock sensor 301 may be configured to sense a latch status of access door 501.
Referring now to FIG. 8, a plurality of overhead storage bins 800 is depicted according to some embodiments. Overhead storage bins 800 are shown with output devices 305a-308a, which may indicate a respective status of each overhead storage bin. For example, in some aspects, central controller 205 may be operatively connected to the plurality of overhead storage bins 800. Central controller 205 may centrally monitor bins 800 by connecting to the microcontrollers associated with each of the bins (e.g., microcontroller 204), accessing sensor data, and using the sensor data to determine one or more statuses of the overhead storage bins.
In some aspects, central controller 205 may determine, based on sensor data, whether an item is likely to fall from any one of overhead storage bins 800, and output the information to a central output device 206, which may be located in a location on the aircraft viewable by aircraft personnel (e.g., a flight attendant, a captain, etc.). In some aspects, central controller 205 may output information indicative of space status, weight status, latch/lock status, falling hazard, etc., for each of the plurality of stowage bins 800.
FIG. 9 depicts one embodiment of a user interface of a system for monitoring an overhead storage bin 201, in accordance with some embodiments. Referring now to FIG. 9, interface 900 may include a depiction of an aircraft 901, with a corresponding status 902 for each of the plurality of overhead storage bins 800. In some aspects, central controller 205 may retrieve proximity data, weight data, and a latch status from a plurality of overhead storage bins 800 connected to central controller 205. Central controller 205 may then determine, for each of the plurality of overhead storage bins 800, a hazard status indicative of whether an item stowed in the overhead storage bins may fall from the bin. In some aspects central controller 205 may output the hazard status for each of the plurality of overhead storage bins 800 on an output device of each of the plurality of overhead storage bins 800 (e.g., on output device 203 associated with each bin). The hazard status may be indicative of whether an item stowed in the respective overhead storage bin may fall from the bin.
In other aspects, central controller 205 may also output the hazard status 902 on a central output device 206. Central output device 206 may output user interface 900 as depicted in FIG. 9, which may indicate hazard statuses for the bins 800. For example, interface 900 may include a color code 903 indicating the particular status for each overhead storage bin. Mobile device 207 may also receive transmission from central output device 206, and output user interface 900. For example, mobile device 207 may be a tablet or handheld device used by a flight attendant. In other embodiments, mobile device 207 may be a handheld device of a passenger.
Referring now to FIG. 10, a method for monitoring an overhead storage bin is depicted, according to some embodiments. At step 1001, central controller 205 may retrieve proximity data, load data, and latch status data from overhead storage bin 201. At step 1002, central controller 205 may determine, based on the space status, weight data, and the latch status, a probability indicative of whether an item stowed in the overhead storage bin 201 may fall. In some aspects, central controller 205 may output, based on the probability, an indication on an output device (e.g., output device 203) configured on an exterior surface of overhead storage bin 201. Output device 203, central output device 206, IFE display 208, mobile device 207, and/or any combination thereof may display the indication. Output device 203 may also output information with respect to each individual status (e.g., the space available, the weight loading, and/or the lock status).
Referring now to FIG. 11, a flow diagram for a method 1100 for monitoring a plurality of overhead storage bins is described, according to some embodiments. In some aspects, central controller 205 may retrieve proximity data, weight data, and a latch status from a plurality of overhead storage bins 800 connected to the central controller 205. In some aspects, controller 205 may determine, for each of the plurality of overhead storage bins 800, a hazard status indicative of whether an item stowed in the overhead storage bins may fall from the bin. In some embodiments central controller 205 may output the hazard status for each of the plurality of overhead storage bins 800, on an output device 203 of each of the plurality of overhead storage bins 800, where the hazard status is indicative of whether an item stowed in the respective overhead storage bin may fall from the bin. Output device 203, central output device 206, mobile device 207, IFE display 208, and/or any combination thereof may display the indication.
