Description

Technical Field

[0001] The present disclosure generally relates to disinfection systems, and more particularly to aircraft disinfection systems and equipment. Background Art

[0002] During a pandemic, it is crucial to monitor the contamination of surfaces due to pathogenic microorganisms (e.g., viruses or bacteria). For containing a pandemic without interrupting international trade and travel, disinfecting frequently touched surfaces such as those inside an aircraft is as necessary as disinfecting body parts. Pathogenic microorganisms can remain active on surfaces for days and thus enable rapid spread of infection. For example, the pathogenic microorganisms can be coronaviruses, Ebola virus, Nipah virus, Salmonella typhi, Mycobacterium tuberculosis, etc. Local outbreaks of epidemics such as COVID-19 can spread domestically or internationally at a higher speed through air travel. During such outbreaks, air travel is severely restricted, causing social and economic losses to countries.

[0003] Ultraviolet (UV) light waves in the wavelength range of 100 nanometers (nm) to 280 nm are germicidal in nature. The germicidal wavelength range of UV corresponds to short-wavelength UV, also known as UV-C. Due to the development of inexpensive and energy-efficient UV-C light-emitting diodes (LEDs), UV-C is used for disinfecting surfaces, water, or air.

[0004] At the current state of the art, there are techniques for disinfecting surfaces using UV-C light. However, the prior art does not provide an overall disinfection system and is limited to a few surfaces and enclosures in an aircraft, such as kitchens, air ducts, aircraft cabins, and lavatories. In addition, the technique requires the use of UV light for disinfection in the absence of passengers or crew members. However, during a continuous flight, surfaces such as trays, the handles of overhead luggage compartments, and the handles of lavatories are frequently touched by multiple passengers and crew members.

[0005] Therefore, there is a need for systems and devices for disinfecting aircraft surfaces at frequent intervals during the duration of a flight to inhibit the spread of pathogenic microorganisms in the aircraft. Summary of the Invention

[0101] Exemplary embodiments are described with reference to the accompanying drawings. Where convenient, the same reference numerals are used in all the drawings to denote the same or similar parts. While examples and features of the disclosed principles are described herein, modifications, adaptations, and other embodiments are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered only exemplary, and the true scope and spirit be indicated by the appended claims. Additional illustrative embodiments are listed below.

[0102] In Figure 1 , an exemplary aircraft cabin 100 in which various embodiments can be employed is shown. The aircraft cabin 100 can include a plurality of passenger seats (e.g., passenger seat 102a, passenger seat 102b, passenger seat 104a, and passenger seat 104b), a plurality of overhead storage bins (e.g., overhead storage bin 106 and overhead storage bin 108), and a lavatory 110. Each of the plurality of passenger seats can include a seat belt (e.g., seat belt 112). In one embodiment, passenger seat 102a can include an armrest 114a, and passenger seat 102b can include an armrest 114b. Additionally, each of armrest 114a and armrest 114b includes a recess (e.g., recess 116), a tray (e.g., tray 118), and a lid (e.g., lid 120). The recess can be configured to store the tray, and the lid is configured to cover the recess when the tray is enclosed in the recess. Further, the tray can be in an open state or a closed state. It can be noted that in the open state, the tray is at least partially outside the recess, and in the closed state, the tray is completely inside the recess. In passenger seat 102a, tray 118 is in the open state, while in passenger seat 102b, the tray is in the closed state and is covered by lid 120. This will be explained in further detail in connection with Figure 5 below.

[0103] The passenger seat 104a may include a rear surface. A frame (e.g., frame 122) may be attached to the rear surface. Additionally, a tray (e.g., tray 124a or tray 124b) may be operatively coupled to at least the first two corners of the frame, and the tray is thus capable of rotating about a pivot axis ( Figure 1 not shown in the figure). The tray may be in an unlocked state such that, in the unlocked state, the tray is at an angle greater than zero with respect to the frame. Alternatively, the tray may be in a locked state such that, in the locked state, the tray is at an angle equal to zero with respect to the frame. In other words, the tray is in full contact with the frame. Additionally, a latch ( Figure 1 not shown in the figure) may cooperate or engage with the tray. For this purpose, the tray may be provided with a notch, cavity, or protrusion with which the latch may engage in the locked state. In the unlocked state, the latch may disengage from the tray. Tray 124a is in the unlocked state, and tray 124b is in the locked state. This will be explained in further detail in conjunction with Figure 4 below.

[0104] Each of the passenger seats is also provided with a seat belt, such as seat belt 122. The seat belt may include a first portion attached to a first fabric portion of the seat belt and a second portion attached to a second fabric portion of the seat belt. For example, the first portion may be the female portion of a buckle for fastening the seat belt. For example, the second portion may be the male portion of the buckle. Thus, it can be noted that the first portion is configured to receive the second portion for fastening the seat belt. This will be explained in further detail in conjunction with Figure 2 and Figure 3 below. Additionally, each of the plurality of overhead storage bins may include a handle (e.g., handle 126a or handle 126b). Additionally, the lavatory 110 may include a handle 128.

[0105] It should be understood that during flight, various aircraft surfaces may be contacted by body parts (e.g., fingers, hands, arms, elbows, etc.). By way of example, the aircraft surfaces may include but are not limited to seat belt 112, tray 118, trays 124a and 124b, handles 126a and 126b, and handle 128. It can be noted that body parts may be sources of contamination. Infectious diseases may be transmitted through contamination on at least one of the aircraft surfaces. By way of example, the infectious diseases may include but are not limited to coronavirus disease (COVID-19), Ebola virus disease, H1N1 infection, Nipah virus infection, Salmonella infection, tuberculosis, etc. Thus, even during the duration of a flight, each of the aircraft surfaces may need to be disinfected regularly.

[0106] To achieve this, multiple sets of ultraviolet (UV) light emitting diodes (LEDs) can be attached at different locations of the aircraft cabin 100. The multiple sets of UV LEDs can be configured to disinfect each of the aircraft surfaces. It should be understood that light within the wavelength range of UV is germicidal. Exposure to UV light for a predetermined threshold time can disinfect each of the aircraft surfaces. However, UV light may need to be avoided from human contact because UV light is carcinogenic. Therefore, the disinfection of each of the aircraft surfaces by UV light can be carried out when there are no passengers or crew on the aircraft or when the aircraft is in the air and operating in isolation from people. This will be discussed in detail in conjunction with Figures 2 to 10 Detailed discussion.

[0107] Now referring to Figure 2 , according to an exemplary embodiment, multiple views of an aircraft disinfection system 200 for disinfecting a first portion 202 of a seat belt are shown. The seat belt can be the seat belt 112 of the aircraft cabin 100. The multiple views of the aircraft disinfection system 200 can include a perspective view 204a, a perspective view 204b, a top view 204c, a side view 204d, and a front view 204e. The aircraft disinfection system 200 can include a first portion 202 (which can be the female portion of the buckle) of a seat belt (e.g., seat belt 112) attached to a first fabric portion 206 of the seat belt. It can be noted that the seat belt can include a second portion ( Figure 2 not shown in Figure 2 and which can be the male portion of the buckle) attached to a second fabric portion of the seat belt ( Figure 3 not shown). The first portion 202 is configured to receive the second portion for fastening the seat belt. The second portion and the second fabric of the seat belt will be explained in detail in conjunction with Figure 3 . The perspective view 204a shows the first portion 202 of the seat belt and the first fabric portion 206. The aircraft disinfection system 200 can also include a first storage housing 208. It can be noted that the first storage housing 208 is configured to completely enclose the first portion 202 for disinfecting it.

[0108] The first storage housing 208 may include a first inner wall 210, a first set of UV LEDs 212, and a tongue 214. It can be noted that the first inner wall 210 may be configured to surround the outer surface of the first portion 202. In addition, the first set of UV LEDs 212 may be attached to the first inner wall 210. The first set of UV LEDs 212 may be configured to disinfect the outer surface of the first portion 202. In some embodiments, the first set of UV LEDs 212 may include at least one UV-C LED. In addition, the tongue 214 may be configured to cooperate with the first portion 202 of the seat belt 112. Perspective view 204b shows the cooperation between the tongue 214 and the first portion 202. In perspective view 204b, it is depicted that when the first portion 202 is fully inserted inside the first storage housing 208, the tongue 214 may lift the flap 202a of the first portion 202 so as to disinfect the inner wall of the flap 202a ( Figure 2 not shown in the figure) and the area of the first portion 202 that was covered by the flap 202a before being lifted. It can be noted that the tongue 214 may be fixed within the first storage housing 208 and may be at least partially inside the first portion 202. In another embodiment, the tongue 214 may be entirely inside the first portion 202.

[0109] A second set of UV LEDs 216 may be attached to each surface of the tongue 214. The second set of UV-C LEDs 216 is shown in front view 204e. It can be noted that the second set of UV LEDs 216 may be configured to disinfect the inner surface of the first portion 202. In one embodiment, the second set of UV LEDs 216 may disinfect the inner wall of the flap 202a ( Figure 2 not shown in the figure) and the area of the first portion 202 that was covered by the flap 202a before being lifted. In some embodiments, the second set of UV LEDs 216 may include at least one UV-C LED. Top view 204c shows the first portion 202 enclosed by the first storage housing 208. Side view 204d shows the cooperation between the tongue 214 and the first portion 202. Front view 204e shows the first portion 202 enclosed by the first storage housing 208.

[0110] In some embodiments, the first storage housing 208 includes a first slit 218 (depicted in side view 204d) that is configured to receive the first fabric portion 206. The first slit 218 may include a first pair of rollers that may cooperate with the first fabric portion 206 ( Figure 2(not shown in the figure). In other words, the first fabric portion 206 can pass through the first slit 218 and then be attached or affixed to the first portion 202. It can be noted that the first pair of rollers enables the first receiving housing 208 to slide on the first fabric portion 206 to enclose the first portion 202. As previously discussed, the first fabric portion 206 passes through the first receiving housing 208 via the first slit 218. In one embodiment, the first receiving housing 208 can include a first motorized mechanism ( Figure 2 (not shown in the figure). The first motorized mechanism can be configured to activate the first pair of rollers to slide the first receiving housing 208 on the first fabric portion 206. For example, the first motorized mechanism can be an electric motor.

[0111] The aircraft disinfection system 200 can also include a first set of sensors ( Figure 2 (not shown in the figure). It can be noted that the first set of sensors can be configured to determine the complete enclosure of the first receiving housing 208 around the first portion 202. For example, the first set of sensors can include, but are not limited to, proximity sensors, cameras, ultrasonic sensors, etc. Additionally, the aircraft disinfection system 200 can include a controller ( Figure 2 (not shown in the figure), which can be communicatively coupled to each of the first set of UV LEDs 212, the second set of UV LEDs 216, the first set of sensors, and the first motorized mechanism.

[0112] In response to a disinfection start signal, the controller can be configured to instruct the first motorized mechanism to slide on the first fabric portion 206 to enclose the first receiving housing 208. For example, once the aircraft has been emptied of passengers and there are no crew members or passengers on the aircraft, a disinfection start signal can be generated. Alternatively, when the second portion of the seatbelt is not inserted into the first portion 202, a disinfection start signal can be generated. In other words, when the male portion of the seatbelt buckle is removed from the female portion of the seatbelt buckle, a disinfection start signal can be generated.

[0113] Additionally, the controller may be configured to activate each of the first set of UV LEDs 212 and the second set of UV LEDs 216 in response to the first set of sensors determining that the first storage housing 208 completely encloses the first portion 202. After a predetermined time period has elapsed since the activation of the first set of UV LEDs 212 and the second set of UV LEDs 216, the controller may also be configured to instruct the first motorized mechanism to slide over the first fabric portion 206 so as to expose the first storage housing 208. In some embodiments, the controller may be configured to deactivate each of the first set of UV LEDs 212 and the second set of UV LEDs 216 in response to the first set of sensors determining that the first storage housing 208 partially encloses the first portion 202. In other words, if someone attempts to pull out the first portion 202 currently enclosed by the first storage housing 208, the controller may deactivate each of the first set of UV LEDs 212 and the second set of UV LEDs 216. The controller may also be configured to deactivate each of the first set of UV LEDs 212 and the second set of UV LEDs 216 in response to the first set of sensors detecting any movement. It will be apparent to those skilled in the art that the aircraft disinfection system 200 may not be limited to aircraft and may be implemented in trains, buses, cars, trucks, or any of their means of transportation. The aircraft disinfection system 200 may also be implemented in public use areas (e.g., movie theaters, shopping malls, etc.).

[0114] Now referring to Figure 3 , in accordance with an exemplary embodiment, multiple views of an aircraft disinfection system 300 for disinfecting a second portion 302 of a seat belt are shown. The seat belt may be the seat belt 112 of the aircraft cabin 100. The multiple views of the aircraft disinfection system 300 may include a perspective view 304a, a top view 304b, a front view 304c, and a side view 304d. The perspective view 304a shows the second portion 302 attached to the second fabric portion 306 of the seat belt. Additionally, the aircraft disinfection system 300 may include a second storage housing 308 configured to enclose the second portion 302. The second storage housing 308 may include a second inner wall 310 and a third set of UV LEDs 312. It may be noted that the second inner wall 310 may be configured to surround the second portion 302. The third set of UV LEDs 312 may be attached to the second inner wall 310. It may be noted that the third set of UV LEDs 312 is configured to disinfect the second portion 302. In some embodiments, the third set of UV LEDs 312 may include at least one UV-C LED.

[0115] In some embodiments, the second receiving housing 308 includes a second slit 314 (depicted in side view 304d), which is configured to receive the second fabric portion 306. In other words, the second fabric portion 306 passes through the second slit 314 and is attached to the second portion 302. Additionally, the second slit 314 may include a second pair of rollers ( Figure 3 not shown in) that may cooperate with the second fabric portion 306. In other words, the second pair of rollers enables the second receiving housing 308 to slide over the second fabric portion 306 to enclose the second portion 302. The second fabric portion 306 passes through the second receiving housing 308 via the second slit 314. In one embodiment, the second receiving housing 308 may include a second motorized mechanism ( Figure 3 not shown in) coupled to the second pair of rollers. The second motorized mechanism may be configured to activate the second pair of rollers to slide the second receiving housing 308 over the second fabric portion 306. For example, the second motorized mechanism may be an electric motor.

[0116] The aircraft disinfection system 300 may also include a second set of sensors ( Figure 3 not shown in) within the second receiving housing 308. It may be noted that the second set of sensors may be configured to determine the complete enclosure of the second portion 302 by the second receiving housing 308. By way of example, the second set of sensors may include, but are not limited to, proximity sensors, cameras, ultrasonic sensors, etc. The aircraft disinfection system 300 may also include a controller ( Figure 3 not shown in) that is communicatively coupled to each of the third set of UV LEDs 312, the second set of sensors, and the second motorized mechanism. The controller may be configured to instruct the second motorized mechanism to slide over the second fabric portion 306 to enclose the second receiving housing 308 in response to a disinfection start signal, which has been Figure 2 discussed in detail in.

[0117] In addition, the controller may be configured to activate the third set of UV LEDs 312 in response to the second set of sensors determining that the second storage cover 308 completely encloses the second portion 302. The controller may also be configured to instruct the second motorized mechanism to slide on the second fabric portion 306 to expose the second storage cover 308 after the expiration of a predetermined time period. In some embodiments, the controller may be configured to deactivate the third set of UV LEDs 312 in response to the second set of sensors determining that the second storage cover 308 partially encloses the second portion 302. In other words, if someone attempts to pull out the second portion 302 currently enclosed by the second storage cover 308, the controller may deactivate the third set of UV LEDs 312. The controller may also be configured to deactivate the third set of UV LEDs 312 in response to any movement detected by the second set of sensors. It will be apparent to those skilled in the art that the aircraft disinfection system 300 may not be limited to aircraft and may be implemented in trains, buses, cars, trucks, or any other means of transportation thereof. The aircraft disinfection system 300 may also be implemented in public use areas (e.g., movie theaters, shopping malls, etc.).

It may be noted that the tray 402 may be configured to be in a locked state and / or an unlocked state based on a rotation about the pivot axis 408. It may also be noted that in the unlocked state, the tray 402 is at an angle greater than zero relative to the frame 406, and in the locked state, the tray 402 is at an angle equal to zero relative to the frame 406. The tray 402 is shown in each of the top view 404d, the front view 404e, and the side view 404f as being in an unlocked state. The tray 402 is shown in each of the perspective view 404a, the top view 404b, the front view 404c, and the side view 404g as being in an unlocked state.

[0120] The aircraft disinfection system 400 may further include a set of UV LEDs 410 attached to the exposed surface of the frame 402. In the locked state, the tray 402 may face the exposed surface of the frame 402. It can be noted that the set of UV LEDs 410 may be configured to disinfect the tray 402 when the tray 402 is in the locked state.

It can be noted that in the locked state, the tray 402 closes and activates each of the at least one switch. The frame 406 may further include a latch 414 that may cooperate with the tray 402. It can be noted that in the locked state, the latch 414 may engage with the tray 402, and in the unlocked state, the latch 414 may disengage from the tray 402. To this end, the tray 402 may be provided with a notch, cavity, or protrusion with which the latch 414 may engage in the locked state.

[0121] The frame 406 may include a controller that may be communicatively coupled to at least one switch and the latch 414. The controller may activate the set of UV LEDs 410 when a set of conditions is met. It can be noted that the set of conditions may include each of the tray 402 being in the locked state, at least one switch being activated, and the latch 414 engaging the tray 402. In some embodiments, the frame 406 may further include at least one sensor that may be configured to generate a deactivation signal based on a predefined criterion. For example, the predefined criterion may be a transition of the tray 402 from the locked state to the unlocked state. As another example, the predefined criterion may be the detection of movement or a body part of a person. The controller may be communicatively coupled to at least one sensor. The controller may thus be configured to deactivate the set of UV LEDs 410 in response to the deactivation signal generated by at least one sensor. It can be noted that at least one sensor may be located at the outer perimeter of the frame 406 and may be enclosed by the tray 402 in the locked state.

The closed state is shown in the side view 1006b, and the open state is shown in the side view 1006c. The aircraft disinfection device 1000 can include at least one locking mechanism. The at least one locking mechanism can be configured to engage with the first surface 1010 in the closed state and disengage from the first surface 1010 in the open state. For example, when the enclosed area is a lavatory, the locking mechanism can be a sliding latch that can slide in one horizontal direction to close the door and slide in the opposite horizontal direction to open the door. Additionally, the aircraft disinfection device 1000 can include a controller ( Figure 10(not shown in the figure), the controller is communicatively coupled to each of the set of UV LEDs 1016, at least one switch, and at least one locking mechanism. The controller can be configured to activate the set of UV LEDs 1016 when each of the at least one switch is activated and the locking mechanism engages the first surface 1010 in the closed state.

[0144] The aircraft disinfection device 1000 may further include a rotating mechanism 1018, which is operatively coupled to the curved housing 1008 and is configured to move the curved housing 1008 from a first position to a second position and at least one intermediate position.

It is obvious to those skilled in the art that the aircraft disinfection device 1000 is not limited to aircraft and can be implemented in trains, buses, cars, trucks, or any other means of transportation. The aircraft disinfection device 1000 can also be implemented in public use areas (such as cinemas, shopping malls, etc.).

[0147] As those skilled in the art will further appreciate, current disinfection systems lack a mechanism for effectively disinfecting surfaces in an aircraft while passengers and crew are on board. The above-described technology provides for disinfecting surfaces in an aircraft. In particular, the above-described technology provides for disinfecting surfaces in an aircraft by means of multiple sets of UV LEDs. Using the above-described technology, passengers and crew can disinfect surfaces such as tray tables, lavatory door handles, or overhead bin handles. These technologies provide an effective means of preventing UV light radiation from contacting a user's body parts. In the absence of passengers and crew, surfaces such as the locking portions of seat belts can be disinfected before or after a flight. These technologies provide enclosures such as a storage housing for storing the locking portion of a seat belt, a frame and recess for storing a tray table, and a curved housing for covering a handle. Each of the multiple sets of UV LEDs is attached inside such an enclosure. In addition, these technologies employ sensors to detect the presence of a user's body part inside the enclosure. The sensors activate the UV LEDs in the closed or locked state of the surface to prevent UV light radiation from contacting a user's body part. The above-described technology can be used in combination with existing prior art that uses UV LEDs to disinfect air released from the ducts of an aircraft's air conditioning system, the interior of lavatories, the interior of an aircraft cabin, handheld devices (e.g., in-flight entertainment controllers), and the like.
