Patent Description:
Commercial aircraft typically include an internal cabin that may be divided into numerous sections. A cockpit is generally separated from a passenger cabin, which may include a first class section, a business class section, and a coach section. The passenger cabin may also include one or more work areas for flight personnel, such as galleys, which may include food and beverage storage structures. One or more aisles pass through the passenger cabin and connect each of the passenger sections to one or more paths to one or more doors of the aircraft.

Overhead stowage bins are typically positioned above rows of seats within a commercial aircraft. Each overhead stowage bin is configured to be moved between an open position and a closed position. In the open position, passengers may place carry-on luggage within a moveable bin or bucket. Before the aircraft leaves a terminal, flight attendants ensure that each stowage bin is securely closed.

In order to open a stowage bin, an individual (such as a passenger or flight attendant) physically touches a latch of the stowage bin. For example, the individual first grasps and pulls the latch in order to manipulate the stowage bin into an open position. As can be appreciated, the latch of the stowage bin is touched by numerous individuals many times. Consequently, various germs and bacteria may be present on the latch if the latch is not regularly cleaned. Moreover, certain individuals may find grasping and manipulating the latch difficult. Also, boarding time is often extended by passengers opening individual stowage bin assemblies to determine whether or not there is available space therein for their carry-on luggage.

Additionally, individuals typically are not able to determine whether or not a stowage bin assembly is full when the stowage bin assembly is in a closed position. The stowage bin assembly is typically manipulated and opened to determine whether there is additional space therein. As such, an individual may open the stowage bin assembly only to discover there is no additional space therein, while potentially spreading pathogens via touching the stowage bin assembly.

Moreover, stowage bin assemblies occupy substantial space within an internal cabin. Such space is typically not utilized for anything other than stowing luggage and personal items.

<CIT>, in accordance with a translation of its abstract, states, "This luggage compartment is an enclosed compartment arranged in a space intended to receive travellers in a vehicle. It comprises at least one wall delimiting it and visible from the passenger space inside which it is located. Said wall comprises at least one opening closed by a transparent material.

There is described herein a stowage bin according to claim <NUM>.

There is also described herein a method according to claim <NUM>.

A need exists for an improved stowage bin assembly that allows for individuals to view internal contents without opening the stowage bin assembly. Also, a need exists for a stowage bin assembly that is able to reduce boarding times. Further, a need exists for a stowage bin assembly that reduces the potential of spreading pathogens. Additionally, a need exists for a stowage bin assembly that can provide additional functionality.

With those needs in mind, certain examples of the present disclosure provide a stowage bin assembly, including a front panel configured to be selectively switched between a transparent mode and an opaque mode. A baggage retaining chamber is defined, at least in part, by the front panel. The front panel is moveable between an open position and a closed position.

In some examples, the front panel is further configured to be selectively switched to a translucent mode.

The stowage bin assembly may further include a bucket that includes the front panel. The front panel may be moveably coupled to a bucket.

The front panel includes an electronic layer configured to electronically display information on the front panel. The front panel includes a transparent layer that is selectively dimmable between the transparent mode and the opaque mode. The front panel may include a protective layer. Optionally, the front panel includes a protective layer disposed one or both of in front of or behind the electronic layer and the transparent layer.

The stowage bin assembly may also include a motion sensor that is configured to detect a predetermined gesture that allows the stowage bin assembly to be one or more of locked, unlocked, opened, or closed in a touchless manner.

The stowage bin assembly may further include a bin control unit that is configured to control the front panel.

The stowage bin assembly may further include an actuation sub-system operatively coupled to the front panel. The actuation sub-system may be configured to automatically move the front panel between an open position and a closed position.

The actuation sub-system may include a spring configured to exert a spring force into the front panel, and a motor operatively coupled to a spring. The actuation sub-system may also include one or more dampening arms that control motion between the closed position and the open position.

Certain examples of the present disclosure provide a method of operating a stowage bin assembly. The method includes selectively switching a front panel between a transparent mode and an opaque mode. A baggage retaining chamber is defined, at least in part, by the front panel. The front panel is moveable between an open position and a closed position. Selectively switching may further include selectively switching the front panel to a translucent mode.

Certain examples of the present disclosure provide a vehicle including an internal cabin, and a stowage bin assembly within the internal cabin, as described herein.

Certain examples of the present disclosure provide a stowage bin assembly having a front panel including an electronic layer that is configured to electronically display various graphics, text, and the like on the front panel. The front panel is dimmable, and is further configured to be selectively dimmed.

The stowage bin assembly is configured to be disposed within an internal cabin of a vehicle, such as a commercial aircraft. The front panel is configured to be selectively switched between a transparent mode, a translucent mode, and an opaque mode. In the transparent mode, contents stored within the stowage bin assembly are readily viewable through the front panel. For example, when the front panel is in the transparent mode, individuals are able to see if the stowage bin assembly is filled with baggage, or if there is remaining room therein, even when the stowage bin assembly is in a closed position. For example, the front panel may be within the transparent mode before an aircraft takeoffs, and after the aircraft lands, so individuals can readily see if there is available space within the stowage bin assembly, if contents have shifted, and/or the like. During flight, such as when the aircraft is at a cruise altitude, the front panel may be switched to the opaque mode.

In at least one example, selective switching between different modes are electronically and/or magnetically induced. An electronic display on the front panel can be used to display flight information, entertainment or advertisements, such as when the front panel is dimmed or opaque. Also, the front panel can be configured to be automatically opened and closed.

In at least one example, the stowage bin assembly is configured to be automatically opened and closed without being touched. As such, individuals such as passenger and crew need not touch the stowage bin assembly in order to open and close the stowage bin assembly, which reduces the potential of pathogens (for example, viruses, bacteria, germs, and the like) from spreading.

The electronic display of the front panel can be used to show various information, such flight information, entertainment (for example, movies), advertisements, and the like, such as when the front panel is opaque or dimmed.

In at least one example, the stowage bin assembly is configured to be automatically opened and closed through a predetermined hand gesture, such as a wave or swipe in front of a motion sensor of the front panel. For example, the stowage bin assembly may be configured to open and close in response to a hand being waved in front of the motion sensor.

<FIG> illustrates a schematic block diagram of a system <NUM> for operating stowage bin assemblies <NUM> within an internal cabin <NUM>, according to an example of the present disclosure. In at least one example, the internal cabin <NUM> is within a vehicle, such as a commercial aircraft.

As described herein, the stowage bin assembly <NUM> includes a front panel <NUM> configured to be selectively switched between a transparent mode and an opaque mode. In at least one example, the front panel <NUM> is further configured to be selectively switched to a translucent mode.

At least one of the stowage bin assemblies <NUM> includes a pivot bin or bucket <NUM> that is moveably, such as pivotally or slidably, coupled to fixed structure within the internal cabin <NUM>. For example, the bucket <NUM> is moveably coupled to a strongback, fixed frame, wall, ceiling, and/or the like within the internal cabin <NUM>. In at least one other example, the bucket <NUM> is secured in a fixed relation to other fixed structure within the internal cabin <NUM>.

The bucket <NUM> is coupled to or includes a front panel <NUM>. The front panel <NUM> is a front of portion of the stowage bin assembly <NUM>. In at least one example, the front panel <NUM> is a portion of the bucket <NUM>. In at least one example, the front panel <NUM> is a moveable door coupled to the bucket <NUM>. In at least one example, the front panel <NUM> is connected to a fore end panel <NUM> and an aft end panel <NUM> that is opposite from the fore end panel <NUM>. A baggage retaining chamber is defined, at least in part, between the front panel <NUM>, the fore end panel <NUM>, and the aft end panel <NUM>. Optionally, the bucket <NUM> may not include the fore end panel <NUM> and/or the aft end panel <NUM>. In at least one example, the front panel <NUM> is moveably coupled to a the bucket <NUM>, which may be fixed. The bucket <NUM> can include the end panels, and a rear panel.

The front panel <NUM> includes an electronic layer <NUM> coupled to a transparent layer <NUM>, and a protective layer <NUM>. The electronic layer <NUM> provides an electronic display that is configured to electronically display various information, such as text, graphics, video, and/or the like. For example, the electronic layer <NUM> can be a television screen, monitor, or the like. The electronic layer <NUM> can include a polycarbonate film, transparent metal, and/or the like. In at least one example, the electronic layer <NUM> is a plasma display. In at least one other example, the electronic layer includes a plurality of light-emitting diodes (LEDs), and provides an LED display.

The transparent layer <NUM> is configured to be switched between a transparent mode and an opaque mode, and the transparent layer <NUM> is dimmable. The transparent layer <NUM> is selectively adjustable between the transparent mode, the opaque mode, and adjustably dimmable between the transparent mode and the opaque mode. For example, the transparent layer <NUM> can be gradually dimmed between the transparent mode and the opaque mode. The transparent layer <NUM> can be adjustably dimmed at various levels between the transparent mode and the opaque mode.

In at least one example, the transparent layer <NUM> is an electro-chromic or magnetic film panel. In at least one example, the electro-chromic or magnetic film panel includes two conductive panels sandwiching a gel medium that contains materials capable of generating color in response to an electrical current, where a voltage applied across the gel medium via the two conductive panels causes the gel medium to darken and removal of the voltage across the gel causes the gel to return to a transparent state. One example of a gel electrolyte material usable in an electro-chromic panel may be a polymethylmethacrylate. The electro-chromic panel may further include regions without the gel disposed between the conductive panels, where the region is proximate a motion sensor behind the front panel <NUM>, such that passenger hand motion can be sensed even when the transparent layer is selectively switched to an opaque state.

The protective layer <NUM> is formed of a resilient transparent material. For example, the protective layer <NUM> is a transparent plastic. The protective layer <NUM> can be formed of clear acrylic, for example. As another example, the protective layer <NUM> can be formed of clear plexiglass. In at least one example, the protective layer <NUM> is disposed in front of and behind the electronic layer <NUM> and the transparent layer <NUM>. The protective layer <NUM> protects the electronic layer <NUM> and the transparent layer <NUM> from external forces (for example, being bumped from outside the bucket <NUM>) and internal forces (for example, from baggage within the bucket <NUM> from abutting against the electronic layer <NUM> and/or the transparent layer <NUM>). As an example, the protective layer <NUM> can encase the electronic layer <NUM> and the transparent layer <NUM>.

In at least one example, the electronic layer <NUM>, the transparent layer <NUM>, and the protective layer <NUM> extend along an entire length and height of the front panel <NUM>. For example, the electronic layer <NUM>, the transparent layer <NUM>, and the protective layer <NUM> can form an entirety of the front panel <NUM>. In at least one other example, the electronic layer <NUM>, the transparent layer <NUM>, and the protective layer <NUM> may span only a portion of the length and height of the front panel <NUM>. For example, the front panel <NUM> can be formed of a plastic and/or composite material, and the electronic layer <NUM>, the transparent layer <NUM>, and the protective layer <NUM> can be embedded within such material, positioned within a channel or recess formed in such material, and/or the like.

In at least one example, the front panel <NUM> also includes a motion sensor <NUM> that is configured to detect motion in front of the front panel <NUM>. The motion sensor <NUM> can be disposed at a front, bottom portion of the front panel <NUM>. The motion sensor <NUM> can be a radar motion sensor, a LIDAR motion sensor, an infrared motion sensor, an ultrasonic motion sensor, a laser motion sensor, and/or the like. The motion sensor <NUM> is configured to detect motion within a predetermined range, such as within <NUM> inches (<NUM>) or less in front of the motion sensor <NUM>. Alternatively, the system <NUM> does not include the motion sensor <NUM>.

In at least one example, the stowage bin assembly <NUM> also includes a power supply <NUM>, such as a battery. Optionally, the power supply <NUM> can be a source of power within the internal cabin <NUM>, such as a standard source of alternating current power. Further, optionally, the power supply <NUM> can be disposed outside of the stowage bin assembly <NUM>, such as on or within fixed structure within the internal cabin <NUM>.

The power supply <NUM> is connected to the electronic layer <NUM> and/or the transparent layer <NUM>, such as through one or more wired or wireless connections. The power supply <NUM> provides power for the electronic layer <NUM> and the transparent layer <NUM> to operate.

The stowage bin assembly <NUM> also includes a bin control unit <NUM> that is coupled to the power supply <NUM>, the electronic layer <NUM>, and the transparent layer <NUM>, such as through one or more wired or wireless connections. As shown, the bin control unit <NUM> can be disposed within the stowage bin assembly <NUM>. Optionally, the bin control unit <NUM> may be disposed outside of the stowage bin assembly <NUM>. The bin control unit <NUM> receives electrical power through the power supply <NUM>, and is configured to operate the electronic layer <NUM> and the transparent layer <NUM>. Alternatively, the stowage bin assembly <NUM> does not include a bin control unit <NUM>. Instead, a master control unit <NUM> within the internal cabin <NUM> may be configured to control operation of each of the stowage bin assemblies <NUM>.

In at least one example, the stowage bin assembly <NUM> also includes a user interface <NUM>. The user interface <NUM> is in communication with the bin control unit <NUM> through one or more wired or wireless connections. The user interface <NUM> can be a physical keypad, one or more switches, a monitor, a touchscreen interface, and/or the like. The user interface <NUM> can be on a front surface of the front panel <NUM>. As another example, the user interface <NUM> can be within a baggage retaining chamber of the stowage bin assembly <NUM>. As another example, the user interface <NUM> can be a touchscreen interface provided by the electronic layer <NUM>. As another example, the user interface <NUM> can be outside of the stowage bin assembly <NUM>.

The user interface <NUM> allows an individual to selectively switch the front panel <NUM> between a transparent mode, a translucent mode, and an opaque mode. Optionally, the user interface <NUM> may be a master user interface that is in communication with the master control unit <NUM> within the internal cabin <NUM>. The master control unit <NUM> is in communication with the bin control unit <NUM> of all of the stowage bin assemblies <NUM> and is configured to control operation of the front panel <NUM> from a centralized location. Alternatively, the system <NUM> does not include the user interface <NUM>.

In at least one example, the stowage bin assembly <NUM> also includes an actuation sub-system <NUM>. The actuation sub-system <NUM> is configured to automatically open and/or automatically close the bucket <NUM>. The actuation sub-system <NUM> is in communication with the bin control unit <NUM>, such as through one or more wired or wireless connections. Alternatively, the stowage bin assembly <NUM> does not include the actuation sub-system <NUM>.

In operation, the front panel <NUM> is moveable between an open state and a closed state. The front panel <NUM> is operated, such as by the bin control unit <NUM> and/or the master control unit <NUM>, between a transparent mode, a translucent mode, and an opaque mode. In the transparent mode, the transparent layer <NUM> is clear and transparent, thereby allowing individuals to see through the front panel <NUM> into the baggage retaining chamber, whether or not the front panel <NUM> is in the open state or the closed state. In the translucent mode, the transparent layer <NUM> is dimmed, such that the transparent layer <NUM> is not completely transparent and clear. In the translucent or dimmed state, individuals can still see through the front panel <NUM> into the baggage retaining chamber, but the front panel <NUM> is dimmed. The translucent mode allows the electronic layer <NUM> to electronically display information (such as travel information, text, video, and/or the like) on the front panel <NUM>, while also allowing individuals to see through the front panel <NUM>. In the opaque mode, the transparent layer <NUM> is fully dimmed and opaque, thereby blocking viewing into the baggage retaining chamber through the front panel <NUM>. In the opaque mode, the electronic layer <NUM> can electronically display information on the front panel <NUM>.

In order to lock, unlock, open and/or close the bucket <NUM>, an individual gestures a hand, for example, in front of the front panel <NUM> within the predetermined range (such as within <NUM> inches (<NUM>)) of the motion sensor <NUM>. The bin control unit <NUM> is programmed to recognize a gesture, as detected by the motion sensor <NUM>. The gesture is used to lock, unlock, open and/or close the bucket <NUM> within an individual touching the bucket <NUM>. For example, the gesture can be a side-to-side wave in front of the motion sensor <NUM> a predetermined number of times. For example, the side-to-side wave can be three times from end to end of the motion sensor <NUM> over a predetermined time period, such as <NUM> seconds or less. In this manner, the predetermined gesture can be differentiated from individuals walking past the front panel <NUM> or inadvertently being too close to the front panel. The gesture can be repeated a predetermined number of times over a predetermined time period, as recognized by the bin control unit <NUM>. For example, the predetermined number of times can be between <NUM> and <NUM> times, and the predetermined period of time can be <NUM> seconds or less. As noted, the gesture can be a hand wave from side-to-side along a predetermined range length of the motion sensor <NUM>. Optionally, the gesture can be from top to bottom along a predetermined length of the motion sensor <NUM>. As another example, the gesture can be a door knocking motion in front of, but not contacting, the front panel <NUM>.

The bin control unit <NUM> receives a motion signal from the motion sensor <NUM> indicative of motion in front of the front panel <NUM>. The bin control unit <NUM> is configured to recognize the predetermined gesture from the motion signal. If the motion signal received by the bin control unit <NUM> is recognized by the bin control unit <NUM> as the predetermined gesture, the bin control unit <NUM> lock or unlocks the stowage bin assembly <NUM>, and/or operates the actuation sub-system <NUM> to move the front panel <NUM> and/or the bucket <NUM>, such as by opening or closing the front panel <NUM> and/or the bucket <NUM>. If, however, the motion signal received by the bin control unit <NUM> is not recognized by the bin control unit <NUM> as the predetermined gesture, the bin control unit <NUM> does not lock or unlock the stowage bin assembly <NUM>, and/ or operate the actuation sub-system <NUM> to move the bucket <NUM>.

The bin control unit <NUM> can be configured to lock or unlock the stowage bin assembly <NUM> based on the predetermined gesture. For example, the bin control unit <NUM> can be in communication with a lock <NUM> (such as an electronic lock in communication with the bin control unit <NUM> through one or more wired or wireless connections) of the stowage bin assembly <NUM>. In the locked state, the stowage bin assembly <NUM> is not able to be opened. In the unlocked state, the stowage bin assembly <NUM> can be opened. In at least one example, the bin control unit <NUM> is configured to lock and/or unlock the stowage bin assembly <NUM> without opening or closing the stowage bin assembly <NUM>. In at least one other example, the stowage bin assembly <NUM> does not include the lock <NUM>, and the bin control unit <NUM> is configured to open and close the stowage bin assembly <NUM> without locking or unlocking the stowage bin assembly <NUM>.

In at least one example, the master control unit <NUM> is configured to control operation of all of the stowage bin assemblies <NUM>. For example, the master control unit <NUM> can selectively switch the front panels <NUM> between the transparent mode, the translucent mode, and the opaque mode, such as in conjunction with different phases of travel. For example, during boarding and disembarking phases, the master control unit <NUM> may operate the front panels in the transparent mode. During a cruise phase, the master control unit <NUM> may operate the front panels in the opaque mode. Alternatively, the system <NUM> may not include the master control unit <NUM>.

<FIG> illustrates a cross-sectional view of a portion of the front panel <NUM>. The transparent layer <NUM> is disposed over the electronic layer <NUM>. Alternatively, the electronic layer <NUM> is in front of the transparent layer <NUM> toward an outer surface <NUM> of the front panel <NUM>, or the transparent layer <NUM> is behind the electronic layer <NUM> toward an inner surface <NUM> of the front panel <NUM>. The inner surface <NUM> faces the baggage retaining chamber <NUM>.

In at least one example, the protective layer <NUM> includes an outer protective layer 118a that forms at least a portion of the outer surface <NUM>, and an inner protective layer 118b that forms at least a portion of the inner surface <NUM>. Optionally, the protective layer <NUM> includes one of the outer protective layer 118a or the inner protective layer 118b. In at least one embodiment, the protective layer <NUM> fully encases the electronic layer <NUM> and the transparent layer <NUM>.

<FIG> illustrates a cross-sectional view of a portion of the transparent layer <NUM>, according to an example of the present disclosure. As an example, the transparent layer <NUM> can include a first conductive panel <NUM>, a second conductive panel <NUM>, and a gel medium <NUM>. The gel medium <NUM> is sandwiched between the first conductive panel <NUM> and the second conductive panel <NUM>.

<FIG> illustrates a perspective front view of the stowage bin assembly <NUM>, according to an embodiment of the present disclosure. As shown in <FIG>, the front panel <NUM> is in the opaque mode, such that an individual cannot see through the front panel <NUM> into the baggage retaining chamber <NUM> behind the front panel <NUM>.

The front panel <NUM> includes a latch <NUM>, which may include the lock <NUM> (shown in <FIG>). The latch <NUM> may be an actual, physical latch secured to the front panel <NUM>. As another example, the latch <NUM> can be a virtual latch proximate to the motion sensor <NUM> (for example, the virtual latch <NUM> can be shown in front of the motion sensor <NUM>). In at least one example, the electronic layer <NUM> shows an electronic representation of the latch <NUM> on the front example, the electronic layer <NUM> shows an electronic representation of the latch <NUM> on the front panel <NUM>. The electronic layer <NUM> can also show a message <NUM> on the front panel <NUM> indicating instructions for operating the latch <NUM>. The message <NUM> can indicate that the latch <NUM> is configured to be operated in a touchless manner.

<FIG> illustrates a perspective front view of the stowage bin assembly <NUM> having the front panel <NUM> in the transparent mode, according to an example of the present disclosure. Referring to <FIG> and <FIG>, in the transparent mode, the transparent layer <NUM> is clear, transparent, and undimmed. As such, the front panel <NUM> is clear, thereby allowing an individual to see into the baggage retaining chamber <NUM> and see contents <NUM> (such as carry-on baggage) retained therein.

The front panel <NUM> can be in the transparent mode such as when passengers are boarding and/or disembarking from a vehicle. During such periods, individuals may readily view the internal capacity of the stowage bin assembly <NUM>, which allows for quicker boarding (for example, passengers need not open the stowage bin assembly <NUM> to determine available capacity), and increased safety (for example, individuals can readily see if contents within the stowage bin assembly <NUM> shifted during flight).

<FIG> illustrates a perspective front view of the stowage bin assembly <NUM> having the front panel <NUM> in the translucent mode, according to an example of the present disclosure. Referring to <FIG> and <FIG>, in the translucent mode, the transparent layer <NUM> is dimmed so as not to be fully clear. However, in the translucent mode, the dimmed transparent layer <NUM> still allows an individual to view the contents of the baggage retaining chamber <NUM>. In the translucent mode, the electronic layer <NUM> may electronically show various forms of information on the front panel <NUM>, such as text, graphics, video, and/or the like.

The front panel <NUM> can be in the translucent mode such as when passengers are boarding and/or disembarking from a vehicle. During such periods, individuals may readily view the internal capacity of the stowage bin assembly <NUM>.

<FIG> illustrates a perspective front view of the stowage bin assembly <NUM> having the front panel <NUM> in the opaque mode, according to an example of the present disclosure. Referring to <FIG> and <FIG>, in the opaque mode, the transparent layer <NUM> is opaque (for example, fully dimmed or darkened) so as not to allow viewing through the front panel <NUM>. In the opaque mode, the electronic layer <NUM> may electronically show various forms of information <NUM> on the front panel <NUM>, such as text, graphics, video, and/or the like.

The information <NUM> may include advertisements, available products, available food and beverage items, safety information, flight parameters (for example, altitude, air speed, position), and/or the like. In at least one example, the information <NUM> can include video information, such as commercials, television shows, movies, and/or the like.

The front panel <NUM> can be in the opaque mode during one or more phases of travel. For example, the front panel <NUM> can be in the opaque mode when an aircraft is cruising or at other times when indication of available space within the stowage bin assembly <NUM> is unnecessary.

<FIG> illustrates an end view of the stowage bin assembly <NUM>, according to an embodiment of the present disclosure. In at least one example, the stowage bin assembly <NUM> includes the actuation sub-system <NUM>. In some examples, the actuation sub-system <NUM> includes a motor <NUM> operatively coupled to a spring <NUM>, such as a spiral spring. The spring <NUM> exerts a spring force into the front panel <NUM>, such as an internal, rear surface of the front panel <NUM>. The motor <NUM> and the spring <NUM> are disposed proximate a top of the stowage bin assembly <NUM>, such as proximate to a pivotal coupling of the front panel <NUM> and a fixed portion <NUM> of the stowage bin assembly <NUM>.

The actuation sub-system <NUM> further includes a moveable arm <NUM> coupled between the front panel <NUM> and a rear, lower portion of the stowage bin assembly <NUM>. For example, a first pivot joint <NUM> pivotally couples the arm <NUM> to the front panel <NUM>, and a second pivot joint <NUM> pivotally couples the arm <NUM> to the fixed portion <NUM>. The arm <NUM> includes an extension piston <NUM> moveably retained by a dampening sleeve <NUM>. In at least one example, a moveable arm <NUM> as shown is disposed at either end of the stowage bin assembly <NUM>. As another example, only one end includes the moveable arm <NUM>. The arm(s) <NUM> provide dampening members that are configured to control a rate of motion of the front panel <NUM> between the closed position and the open position. As such, the arm(s) <NUM> is a dampening arm.

In at least one example, the motor <NUM> is in communication with the bin control unit <NUM> (shown in <FIG>), such as through one or more wired or wireless connections. The motor <NUM> is configured to rotate the spring <NUM>, such as in the direction of arc A.

As described herein, referring to <FIG> and <FIG>, the motion sensor <NUM> is configured to detect the predetermined gesture The bin control unit <NUM> then operates the actuation sub-system <NUM> to automatically open and/or close the front panel <NUM>.

Force needed to open the front panel <NUM> is stored within the spring <NUM> as strain energy. When the bin control unit <NUM> receives a signal from the motion sensor <NUM> to open the front panel <NUM>, the bin control unit <NUM> can unlatch the front panel <NUM>. The stored strain energy within the spring <NUM> moves in the direction of arc A', thereby opening the front panel <NUM>. For example, the spring <NUM> includes an exposed end <NUM> that abuts into a rear surface of the front panel <NUM>, thereby forcing the front panel <NUM> open. The arm <NUM> provides a dampening effect to control the rate of opening, in order to ensure that the front panel <NUM> opens safely.

The weight of the front panel <NUM> allows for the front panel <NUM> to be easily closed via a slight pull force from the arm <NUM> in the direction of arc B. The bin control unit <NUM> can operate the motor <NUM> to rotate the spring <NUM> in the direction of arc A to reduce the force applied by the spring <NUM> into the front panel <NUM>, thereby allowing the front panel <NUM> to close.

Optionally, the actuation sub-system <NUM> can be configured differently than shown. For example, the actuation sub-system <NUM> can include hydraulic, pneumatic, electronic, or other such actuators coupled to the front panel <NUM>. For example, a rotary engine can be coupled to a pivot axle extending through at least a portion of the front panel <NUM>. Alternatively, the stowage bin assembly <NUM> does not include an actuation sub-system.

<FIG> illustrates a front perspective view of a vehicle, such as an aircraft <NUM>. The aircraft <NUM> includes a propulsion system <NUM> that includes two engines <NUM>, for example.
