20250236414
This nonprovisional application claims the benefit of priority of Indian Provisional Application No. 202441004928 filed Jan. 24, 2024 for SYSTEMS AND METHODS FOR MONITORING STORAGE PROVISIONS IN A CONVEYANCE, which is hereby incorporated by reference in its entirety.
The present disclosure relates generally to systems and methods for sensing objects and providing alerts, and more particularly, to systems and methods for implementation in a conveyance and configured to activate during a predefined phase of travel, sense the presence of objects in storage provisions, and alert persons to the sensed objects such that the objects are retrieved before exiting the conveyance.
Conveyances such as aircraft include storage provisions for temporary use while on board the conveyance. For example, in an aircraft, storage provisions may be provided for the passengers and the flight crew. Storage provisions may include compartments, closets, shelves, bins, pockets, drawers, etc. The number and type of storage provisions may vary between passenger and crew compartments, as well as between different passenger seating classes. For example, business, first, and super first class seating classes may include a greater number and variety of storage provisions as compared to economy seating classes considering the different seating densities, living spaces, privacy configurations, furniture, and expectation of amenities commensurate with higher fares.
While on board the aircraft or other conveyance, the passengers and crew may utilize the various storage provisions available to them to store personal belongings such as luggage, bags, computer cases, purses, clothing, umbrellas, wallets, passports, keys, jewelry, and electronic devices. While personal belongings may be stored for comfort and convenience, some personal belongings may be required to be stowed in preparation for taxi, takeoff, and landing (TTOL).
At the conclusion of a flight or other mode of travel, the responsibility falls on the passengers and the crew to remember to gather their personal belongings. In some cases, leaving personal belongings behind may be an inconvenience. In other cases, leaving personal belongings behind, such as important and frequently used items such as passports, wallets, purses, keys, computers, and smart phones, is immediately disruptive to the owner. In addition, leaving personal belongings behind places a continuing burden on the crew and carrier to search for, retrieve, secure, communicate, and return the lost items to their owner. When personal belongings are late getting returned, or lost altogether, customer dissatisfaction with the carrier increases.
While reminder systems are known for vehicles, traditional solutions do not operate based on the occupancy state of the vehicle nor the phase of travel, and therefore do not operate in an efficient and power saving manner important for conveyances such as aircraft. In addition, traditional solutions focus on electronic devices such as smart phones, and therefore require reminder systems that are able to establish a communication link with the monitored devices.
Therefore, what is needed is a storage monitoring solution applicable to all types of conveyances, storage provisions, and personal belongings, and which operates in an energy-efficient and customizable manner.

Broadly, embodiments of the inventive concepts disclosed herein are directed to systems and methods for monitoring storage provisions in a conveyance such as an aircraft. In use, the systems and methods are configured to detect objects (e.g., personal belongings) temporarily stored in the storage provisions during travel, and alert users to the presence of the stored objects such that the objects are remembered to be retrieved prior to departing the conveyance, for instance when exiting the aircraft. In embodiments, at least one of the monitoring, sensor activation, detection and alerting may correspond to a predefined phase of flight or condition of the conveyance. For instance, the systems and methods may be made active during a landing or deboarding phase of flight to conserve energy. In some embodiments, the sensing portion of the systems and methods may occur throughout the duration of a flight, while the alerting portion of the systems and methods are made active during a particular phase of flight, such as landing and deboarding. In embodiments, at least one indicator is configured to provide the alert, for instance in the form of a visual alert, audible alert, or both.
Advantages of the systems and methods according to the present disclosure include, but are not limited to, a reduction in the number of personal belongings left behind after a flight, a reduction in the search, handling and return efforts of a carrier as they pertain to lost personal belongings, and increased customer experience. The systems and methods according to the present disclosure may be implemented in new and existing (e.g., retro-fit) storage provisions in different seating classes including, but not limited to, business and first class seats, super first class suites, crew quarters, etc.
The system 100 generally includes at least one sensor positioned with respect to at least one storage provision in the conveyance. In use, the at least one sensor is configured to sense or detect at least one object (e.g., personal belonging) positioned in the at least one storage provision. In embodiments, the type of sensor utilized may be determined by the type of storage provision. For example, vision based sensors may be utilized with open shelving, proximity sensors may be utilized with closed compartments, weight-based sensors may be used with drawers, etc. The particular sensor type may be based on the storage provision shape and size. For example, a sensor may be positioned above a floor of a drawer or compartment and configured to emit a detecting field to detect light weight and thin profile objects (e.g., a passport). Intensity patterns may be utilized to identify objects. In another non-limiting example, objects may be sensed utilizing a smart weighting system or strain gauge to detect changes in weight/strain in a bottom plate. Other sensor types may include, but are not limited to, acoustic/ultrasonic sensors, pressure sensors, optical IR arrays, capacitive loop sensors, cameras, light barriers, and Lidar sensors.
In use, the at least one sensor operates to determine the presence or absence of at least one object in the monitored at least one storage provision. The system 100 further includes at least one indicator associated with the at least one sensor. In embodiments, each individual storage provision may include a dedicated indicator configured to indicate to a user the presence or absence of an object in that particular storage provision. For example, a compartment door may be equipped with an indicator in a prominent location readily visible to the user, wherein the indicator includes a light source that may be turned ‘on’ to indicate the presence of a contained object, or ‘off’ to indicate the absence of a contained object. In some embodiments, the indicator may be substantially invisible to the user when the indicator is turned off, and becomes visible when the indicator is turned on. In other embodiments, a centralized indicator may be used instead of or in conjunction with a dedicated indicator. For example, in the case of a passenger suite, individual indicators may be positioned on each storage provision and a comprehensive indicator may be positioned at the suite entrance, inside or outside of the suite, readily visible to the passenger when exiting the suite.
The system 100 further includes a controller 102 communicatively coupled to the at least one sensor and to the at least one indicator. In embodiments, the controller 102 includes processing circuitry configured to receive information from the at least one sensor pertaining to at least one detected object, receive conveyance information pertaining to at least one condition of the conveyance, and activate the at least one indicator when the at least one object is detected and the at least one condition of the conveyance is met. In embodiments, the controller is therefore configured to receive inputs from each of the at least one sensor and from a separate system in the conveyance, and based on the received inputs, activate the at least one indicator.
In embodiments, the separate system may be a phase of flight controller 104 configured to determine and/or receive phase of flight information, for instance information pertaining to landing or deboarding of the aircraft. In embodiments, the phase of flight controller includes processing circuitry configured to determine a sitting position of a passenger seat positioned in the seating area, determine a fastened state of a seat belt of the passenger seat, and communicate with the controller to provide deboarding phase of flight information when the sitting position of the passenger seat is determined to be upright and the fastened state of the seat belt is determined to be unfastened after having been fastened in preparation for landing. Thus, the at least one indicator may be made active when an object is sensed in the at least one storage provision and the conditions are met pertaining to the deboarding phase of flight.
In another embodiment, the phase of flight controller 104 includes processing circuitry configured to determine a sitting position of a passenger seat positioned in the seating area, activate a fasten seat belt sign in preparation for landing, and communicate with the controller to provide deboarding phase of flight information when the sitting position of the passenger seat is determined to be upright and the fasten seat belt sign is deactivated after having been activated in preparation for landing. Thus, the at least one indicator may be made active when an object is sensed in the at least one storage provision and the conditions are met pertaining to the landing phase of flight.
In yet another embodiment, the phase of flight controller is configured to communicate with the controller when landing gear of the aircraft is deployed to provide landing phase of flight information to the controller. Thus, the at least one indicator may be made active when an object is sensed and a condition of the aircraft pertaining to landing is met.
In yet another embodiment, the phase of flight controller is configured to communicate with the controller when a crew announcement is made pertaining to landing to provide landing phase of flight information to the controller.
In yet another embodiment, the phase of flight controller includes processing circuitry configured to determine a sitting position of a passenger seat positioned in the seating area, determine a fastened state of a seat belt of the passenger seat, and communicate with the controller to provide landing phase of flight information when the sitting position of the passenger seat is determined to be upright, the seat belt is determined to be fastened, and aircraft altitude is less than a predefined altitude as indicated on a monitor positioned in the seating area. Thus, the at least one indicator may be made active when an object is sensed in the at least one storage provision, and landing conditions are met pertaining to the landing phase of flight.
For energy savings and other advantages, the system 100 may operate when at least one predetermined condition is met. For example, the system 100 may communicate with a separate aircraft system associated with a passenger seat associated with the monitored storage provisions. In some embodiments, it may be unnecessary and energy wasteful to monitor the occupational status of the storage provisions early in the flight considering passengers may retrieve and stow personal belongings many different times during the duration of the flight. In that case, the system 100 may be activated at or near the conclusion of the flight, for instance in preparation for landing, during the landing phase of flight, while taxiing in from the runway, while deboarding the aircraft, etc. To further save energy, the system 100 may communicate with the separate system configured to determine and provide to the controller 102 the phase of flight and/or occupancy state of a particular seat associated with particular storage provisions.
The separate system, for instance the phase of flight controller 104, may be configured to monitor the sitting position of an adjustable passenger seat as well as an engagement state of a seat belt or other passenger restraint associated with the passenger seat. Such monitoring can be used to determine the phase of flight and/or seat occupancy. In some embodiments, when the passenger seat is determined to be in the upright sitting position for TTOL, and when the passenger seat belt is determined to be engaged, the separate system may inform the controller 102 of the same such that the status information about the seat and seat belt can be used for activation purposes by the system 100. In embodiments, the monitoring process may be activated once the passenger seat is in the TTOL position and the seat belt engaged to minimize power consumption, operation time, cost, etc.
Seat belt engagement can be determined using a contact sensor or the like associated with the engageable components of the seat belt. Passenger seats such as business, premium, and super first-class passenger seats can include physical components such as a seat bottom, seat back, leg rest, armrests, headrest, etc. Each physical component may be operative and/or position adjustable by at least one of rotation, translation, extension, etc. Adjustments may be performed by actuators coupled to their respective seat component(s). Each actuator may be categorized depending on its respective adjustable component and function. For example, independent actuators may operate irrespective of any other actuator, and may be primary driving members that initiate seat motion. Actuators may be grouped to coordinate movements of the various seat components, and a passenger seat may include any number of actuators organized in any predetermined actuator grouping(s).
Traditional actuated passenger seats are configured to adjust between different sitting positions. The instructions for transitioning the seat between different sitting positions is commonly referred to as a ‘motion plan’, and different seat motion plans are executed by a seat controller. Seat motion plans may be provided to transition the seat from any one sitting position to any other sitting position. The activation and coordination of the different seat actuators for completing a seat motion plan is executed via the seat controller. As such, considering the seat controller operates to achieve the different sitting positions, the same seat controller can communicate the current sitting position to the controller of the system 100 such that the sitting position information can be used to selectively activate and deactivate the system 100. The same seat controller can be configured to receive and report the engagement status of the seat belt to the controller. Thus, the seat controller can communicate with the controller to inform the system 100 regarding the position and occupational state of the seat.
A further condition associated with the system 100 activation and deactivation may concern features of the aircraft. For example, the open/closed status of a suite door or the aircraft door may be conveyed to the controller, and that information used to activate the system 100. In some embodiments, the sitting position, seat belt engagement, open state of a suite door can be used separately or collectively to determine a phase of flight and therefore activate or deactivate the system 100 based on the determined phase of flight. For example, if a deboarding phase is determined, the controller may activate the at least one indicator to display an indication of an occupied state of a monitored storage compartment. In another embodiment, the at least one sensor may be made active during a landing preparation phase and the alert aspect of the system 100 made active during a taxiing or deboarding phase. In embodiments, the system 100 may be configured to cycle the at least one sensor according to predetermined active and sleep modes for further energy savings.
In some embodiments, the system 100 is customizable. For example, system activation may be based on a landing confirmation sequence that includes passenger seat TTOL mode and seat belt engagement to initiate the sensing signal results, and once the sensing process is completed, the system 100 may wait for final confirmation before providing final outputs to the respective indicators. Conditions for identifying the landing phase/deboarding may include, but are not limited to, confirmation of TTOL seat position and seat belt engagement, wherein the controller activates the at least one indicator when at least one of the following conditions is met: crew member seat belt disengages; fasten seat belt sign turns off; proximity to destination/arrival airport; announcement by the flight crew; altitude; landing gear deployment; manual override; etc. Such conditions may be used alone or in combination.
In the embodiments described above, a controller is configured to receive, determine, instruct, execute, etc. The controller may include at least one processor, memory, and a communication interface. The processor provides processing functionality for at least the controller and may include any number of processors, micro-controllers, circuitry, field programmable gate array (FPGA) or other processing systems, and resident or external memory for storing data, executable code, and other information accessed or generated by the controller. The processor may execute one or more software programs embodied in a non-transitory computer readable medium (e.g., memory) that implements techniques described herein. The processor is not limited by the materials from which it is formed, or the processing mechanisms employed therein and, as such, can be implemented via semiconductor(s) and/or transistors (e.g., using electronic integrated circuit (IC) components), and so forth.
The memory may be an example of tangible, computer-readable storage medium that provides storage functionality to store various data and/or program code associated with operation of the processor, such as software programs and/or code segments, or other data to instruct the processor, and possibly other components of the controller, to perform the functionality described herein. Thus, the memory can store data, such as a program of instructions for operating the controller, including its components (e.g., processor, communication interface, etc.), and so forth. It should be noted that while a single memory is described, a wide variety of types and combinations of memory (e.g., tangible, non-transitory memory) may be employed. The memory may be integral with the processor, may comprise stand-alone memory, or may be a combination of both. Some examples of the memory may include removable and non-removable memory components, such as random-access memory (RAM), read-only memory (ROM), flash memory (e.g., a secure digital (SD) memory card, a mini-SD memory card, and/or a micro-SD memory card), solid-state drive (SSD) memory, magnetic memory, optical memory, universal serial bus (USB) memory devices, hard disk memory, external memory, and so forth.
The communication interface may be operatively configured to communicate with components of the controller. For example, the communication interface may be configured to retrieve data from the processor or other devices, transmit data for storage in the memory, retrieve data from storage in the memory, and so forth. The communication interface may also be communicatively coupled with the processor to facilitate data transfer between components of the controller and the processor. It should be noted that while the communication interface is described as a component of the controller, one or more components of the communication interface may be implemented as external components communicatively coupled to the controller via a wired and/or wireless connection. The controller may also include and/or connect to one or more input/output (I/O) devices (e.g., human machine interface (HMI) devices) via the communication interface. In embodiments, the communication interface may include a transmitter, receiver, transceiver, physical connection interface, or any combination thereof.
From the above description, it is clear that the inventive concepts disclosed herein are well adapted to achieve the objectives and to attain the advantages mentioned herein as well as those inherent in the inventive concepts disclosed herein. While presently preferred embodiments of the inventive concepts disclosed herein have been described for purposes of this disclosure, it will be understood that numerous changes may be made which will readily suggest themselves to those skilled in the art and which are accomplished within the broad scope and coverage of the inventive concepts disclosed and claimed herein.
