Description

Embodiments of the subject matter of the present disclosure relate broadly to systems and methods that can be used to sanitize structures and the air within enclosed structures.

Transporters, such as commercial aircraft, are used to transport passengers between various locations. Systems are currently being developed to sterilize or otherwise sanitize surfaces in order to kill or neutralize various harmful microorganisms or other pathogens. Typical methods of sanitizing the surface inside an aircraft involve a great deal of manual effort by one or more crew members. For example, some crew members may spray cleaning chemicals onto the surface inside an aircraft's internal cabin and wipe it off. Other crew members may also slowly swing a rod that emits ultraviolet (UV) radiation near the surface of the internal cabin. UV radiation can kill or neutralize some microorganisms or other pathogens if maintained in a particular neighborhood of the target surface for at least a specified amount of time.

In addition, many civilian transporters, such as aircraft, have HEPA filters in air conditioning systems that can capture microorganisms and pathogens. The HEPA filter receives and cleans the air leaving or entering the cabin. Frequent cleaning of HEPA filters and cabins between flights is some way to ensure the health of passengers and crew on board the aircraft. Further hygienic methods can be used to supplement HEPA filters and chemical cleaning.

Systems and systems to prevent the spread of pathogens between passengers on a moving transporter, for example, between passengers in the internal cabin of an aircraft in flight, without the risk of harming passengers. A method is needed.

In view of these needs, certain embodiments of the subject matter of the present disclosure provide an ultraviolet (UV) light shielding system comprising multiple UV lamps mounted within an internal cabin of a transporter. The UV lamp is arranged so as to emit UV light in the irradiation field extending along the side of the passenger seat arranged in the internal cabin. The two adjacent irradiation fields are spaced apart to demarcate a protected zone for passengers sitting in one of the passenger seats.

In one or more embodiments, a method for shielding and hygienic passengers in the seat is provided. The method comprises mounting a UV lamp in the internal cabin of the transporter. The UV lamps are mounted to emit and direct UV light into the irradiation field extending along the sides of the passenger seats located in the internal cabin. The two adjacent irradiation fields are spaced apart to demarcate a protected zone for passengers sitting in one of the passenger seats.

In one or more embodiments, a UV light shielding system is provided that includes a plurality of UV lamps, sensors, and control units. The UV lamps are mounted in the internal cabin of the transporter and are arranged to emit UV light in an irradiation field extending along the sides of the passenger seats located in the internal cabin. The two adjacent irradiation fields are spaced apart to demarcate a protected zone for passengers sitting in one of the passenger seats. Sensors are configured to monitor passenger seat occupancy and passenger proximity to UV lamps. The control unit includes one or more processors and is operably connected to UV lamps and sensors. The control unit receives a sensor signal from the sensor and is configured to adjust the output of one or more of the UV lamps based on the presence or absence of passenger seat occupancy and the proximity of the passenger to the UV lamps.

A passenger on a seat incorporating a UV light shielding system according to some embodiments is shown. FIG. 3 shows a perspective view of the internal cabin of an aircraft including a UV light shielding system according to some embodiments. It is a schematic diagram of the UV light shielding system by some examples.

The above overview, and the following detailed description of the particular embodiment, will be better understood by reading in conjunction with the accompanying drawings. It should be understood that the singular element or step following "one (a)" or "one (an)" as used herein does not necessarily exclude a plurality of such elements or steps. Moreover, reference to "one embodiment" should not be construed as excluding the existence of additional embodiments that incorporate the features described herein. Further, unless explicitly stated otherwise, embodiments that "contain" or "have" one or more elements with a particular condition may include additional elements that do not have that condition.

A particular embodiment of the subject matter of the present disclosure provides a UV light shielding system that shields a seat occupant from pathogens along one or both sides of each seat occupant. The system utilizes UV lamps that are specifically mounted, placed and controlled to create virtual shields or side curtains using the UV light emitted by the UV lamps. The shield or side curtain is defined by a UV light field. UV light can be filtered over a specified wavelength or narrow wavelength range that is safe for human tissue. For example, the specified wavelength may be 222 nm. The system provides safe and effective hygiene by integrating UV lamps in locations on one or both sides of the passenger seat, depending on the location of the seat. For example, the middle seat may have UV lamps on both sides, while the window seat farthest from the aisle may have UV lamps only between the window seat and the adjacent seat. UV lamps emit light into multiple areas on either side of the passenger to create a virtual shield of UV light. Some of the UV light collides with the passengers in the seat, but most of the light is in the space along one or both sides of the passenger in the area adjacent to the passenger's upper body and head. Be directed. Therefore, UV light essentially produces a side curtain, similar to a side curtain airbag or stall. The placement and / or control of the UV lamps can avoid irradiation of the passenger's immediate range, such as the passenger's face, without continuing to shield the passenger.

In one or more embodiments, the system emits UV light continuously to continue to sterilize air, surfaces, and people (eg, automatically by passengers, crew, based on sensor data, etc.). Can be controlled. In some embodiments, the UV lamps of the shielding system are mounted in or on both sides of the upper seat portion of the passenger seat structure. In some embodiments, one or more of the UV lamps may be attached to the rear of the seat in front of the passenger instead of the seat occupied by the passenger. An air fan can be installed in the seat structure near the UV lamps to maintain airflow across the UV lamps. The fan air is sanitized by the UV light emitted by the UV lamps and can push unsanitary air away from passengers. Reflectors may be integrated within the UV lamp or placed outside the seating structure to direct the UV light to produce the illuminated shape of the side curtain or stall. Reflectors can be used to direct most of the UV light into the unoccupied space on either side of the passenger and to direct a small amount of UV to the passenger. UV lamps can be electrically connected to existing wiring in the passenger seat, such as wiring for headrest display devices. The UV lamp can receive power from an on-board power source such as one or more generators. In addition, sensors may be used by the system to automatically adjust the power and duty cycle of the UV lamps when the passengers are not in their seats and / or in the immediate range of the UV lamps.

One or more technical effects of the UV light shielding system disclosed herein are pathogens (eg, bacteria and others) on one or both sides of the passenger's head when the passenger is sitting in an internal cabin. Includes the ability to kill or neutralize a significant proportion of (such as viruses). Pathogens in the air can be killed or incapacitated by UV side curtains before reaching the passenger's breathing area. UV light shielding systems can be harmless to passengers as UV light has a specified narrow wavelength or wavelength range that is safe for human tissue. Yet, UV shading systems reflect UV light into the space along the sides of the seat (where the passenger's upper body and head are typically absent) and / or directly from the UV lamp. When it detects a passenger in front (within a specified threshold of UV lamp proximity), it automatically reduces the power to the UV lamp or activates and deactivates the UV lamp to bring the passenger into the immediate range (eg,). You can take steps to avoid exposure to UV light (high doses). For example, the system may temporarily deactivate a UV lamp if it detects that a person is looking directly into the lamp from a distance of a few centimeters. The UV shielding system disclosed herein may supplement other methods for reducing the spread of pathogens among people, such as the use of face masks and social distance.

FIG. 1 shows a perspective front view of the aircraft 10 according to some embodiments of the subject matter of the present disclosure. Aircraft 10 includes, for example, a propulsion system 12 that includes an engine 14. Optionally, the propulsion system 12 may include more engines 14 than shown. The engine 14 is carried by the main wing 16 of the aircraft 10. In some embodiments, the engine 14 may be supported by the fuselage 18 and / or the tail 20. The tail 20 may also support the horizontal stabilizer 22 and the vertical stabilizer 24.

The fuselage 18 of the aircraft 10 defines an internal cabin, which is the cockpit (flight deck or cockpit), one or more work areas (eg, cooking room, crew baggage area, etc.) and one or more passenger areas (eg, crew baggage area). For example, first class, business class, and economy class), including one or more restrooms.

Alternatively, the embodiments of the subject matter of the present disclosure may be used in place of aircraft with various other transporters such as automobiles, buses, rolling stock, ships, and the like. For example, the UV light shielding system disclosed herein can be implemented in an internal cabin of a passenger car, bus, passenger ship, or the like. The embodiments of the subject matter of the present disclosure may also be used for enclosed areas within fixed structures such as commercial and residential buildings. For example, the shielding system disclosed herein may be installed and operate within the scope of theaters, concert halls, religious venues, office buildings, hospitals, shops, auditoriums, classrooms, stadiums, and the like. Persistent UV light of harmless wavelengths can provide continuous sterilization of air and surfaces.

FIG. 2 shows a perspective view of a UV light shielding system 100 within a portion of the internal cabin 122 of an aircraft 10 according to an embodiment of the subject matter of the present disclosure. The internal cabin 122 includes a mounted wall 102 having a window 106 formed within the mounted wall 102. The floor 108 supports a plurality of passenger seats 110. The seats shown in FIG. 2 may be priority seats, such as seats in the first class section or business class section of the internal cabin 122. However, the system 100 disclosed herein can be used in seats within any section of the internal cabin 122, including the economy.

The seat 110 has a cushion 112, a backrest 114, and a headrest cushion 116. The seat 110 has an inboard side 118 and an outboard side 120. The outboard side 120 faces the outboard wall 102. The UV light shielding system 100 in the illustrated embodiment includes two UV lamps 124 integrated into the seat 110. The UV lamp 124 is a light source such as an excimer lamp that emits light in the UV region of the electromagnetic spectrum. For example, a first UV lamp 124A is attached to the front 126 of the backrest 114 on or near the inboard side 118. The second UV lamp 124B is attached to the front 126 of the backrest 114 on or near the outboard side 120. The UV lamp 124 emits UV light forward. The direction and / or magnification of UV light can be controlled. Thereby, the irradiation field 128 constructively creates a side curtain or stall of UV light. The irradiation field 128 of the UV lamp 124 refers to a three-dimensional space within a space defined by the propagation of a wave (eg, a light beam) of UV light emitted by the UV lamp 124. The shape of the field 128 may depend on the mechanical features of the UV lamp 124 such as reflectors, collimators, lenses, etc., in which case it may be controlled to provide a shape with long vertical dimensions and short lateral dimensions. .. The irradiation field 128 may resemble a panel or shield. Irradiation fields 128 sandwich and define a passenger protection zone 130 between them. Passengers are placed within the passenger protection zone 130 when they are properly seated in seat 110. The UV lamp 124 is mounted and arranged to direct UV light so that the irradiation field 128 is generally aligned with the passenger's upper body and head.

FIG. 3 shows a passenger 140 sitting in a seat 142 incorporating the UV light shielding system 100 according to one embodiment. Passenger 140 is located within the protected zone 130. The UV light in the irradiation field 128 is arranged on both sides of the passenger 140. Some of the UV light can hit the passenger's body, such as the shoulders, head, and arms, but most of the UV radiation is directed into the space beside the passenger 140. UV light in the field 128 can kill or neutralize the pathogen in the air before the pathogen can be inhaled by the passenger 140. The UV light shielding system 100 can prevent the spread of at least some pathogens to and from passenger 130 when passenger 140 is in seat 142.

FIG. 4 shows a perspective view of an aircraft internal cabin 150 including a UV light shielding system 100 according to some embodiments. In FIG. 4, the UV lamp 124 is mounted along the rear 152 of the passenger seat 154. The UV lamp 124 is arranged so as to direct the emitted UV light backward toward the seat 154 in the row 156 behind the seat 154 holding the UV lamp 124. The UV lamp 124 is mounted along the backrest 160 of the seat 154 on or near each of the inboard side 162 and the outboard side 164 of the seat 154. The UV light creates a side curtain 164 or stall for the seat 154 in the back row 156 and extends among the passengers sitting in the row 156. Optionally, instead of mounting two UV lamps 124 on one seat 154, as shown in FIG. 4, the most outboard lamp 124 is illustrated without any UV lamp 124. It may be attached instead to the adjacent seat 154.

In some embodiments, at least some UV lamps 124 may be mounted on the ceiling of the internal cabin above the seat 154, in the space along both sides of the seat 154 and the passenger occupying the seat 154. It may be arranged to direct UV light downwards (towards the floor).

FIG. 5 is a schematic diagram of a UV light shielding system 100 (hereinafter referred to as a system 100 in the present specification) according to an embodiment. The system 100 includes a UV lamp 120, a control unit 170, a sensor 178, and a switching and / or conversion device 180. The UV lamp 124 is powered by an outboard power source 172 that supplies power. The power source 172 may be a generator that converts mechanical energy into electrical energy. Various conductive wires and cables can conduct power from the power supply 172 to the UV lamp 124. For example, the UV lamp 124 may utilize the same conductive path that powers other components in the cabin, such as personal lights and headrest display units. For example, the UV lamp 124 may be plugged into the same electronic circuit package that controls the cabin lighting.

The control unit 170 is operably connected to the UV lamp 124, the switching and / or power conversion device 180, and the sensor 178 via a wired and / or wireless communication path. The control unit 170 generates a control signal that controls the operation of the UV lamp 124. The generated control signal may be based on a signal (eg, data) received from the sensor 178. The control unit 170 represents a hardware circuit comprising and / or being connected to one or more processors 182 (eg, one or more microprocessors, integrated circuits, microcontrollers, field programmable gate arrays, etc.). The control unit includes and / or is connected to a tangible, non-transient computer-readable storage medium (eg, memory) 184. For example, the memory 184 may store programmed instructions (eg, software) executed by one or more processors 182 to perform the operations of the control unit 170 described herein.

The control unit 170 may control the UV lamp 124 by controlling the presence and amount of power (eg, voltage and / or current) supplied to each of the UV lamps 124. In this function, the control unit 170 may utilize the switching and / or power conversion device 180. The switching and / or power conversion device 180 may include one or more solid state relays, electromechanical relays, optical switches, power converters (eg, direct current and direct current, direct current and alternating current), and the like. The control unit 170 may deactivate or shut off one or more of the UV lamps 124 and change the non-zero output of one or more of the UV lamps 124 via the switch and / or power conversion device 180. can. The switch and / or power conversion device 180 not only switches the lamp 124 on (eg, boots and emits UV light) and off (eg, does not boot and emits UV light), but also the associated UV. It may allow variable control over the amount of power supplied to the lamp 124. The variable power level may include multiple settings such as low, medium, and high.

In one or more embodiments, the UV light emitted by the UV lamp 124 allows the seat occupants (eg, passengers and crew) to be exposed to the UV light for extended periods of time without harm. Is controlled. For example, the emitted UV light can have a specified wavelength or a narrow band wavelength that has been experimentally determined to be harmless to human tissue over long exposures. Therefore, even if the UV lamp 124 constantly emits UV light throughout the duration of the flight, the passengers cannot be harmed. In one non-limiting example, the designated wavelength is 222 nm. Hygienic UV light with a wavelength of 222 nm has been shown to kill pathogens instead of inactivating them (viruses, bacteria, etc.). In contrast, UVC light with a wavelength of 254 nm inactivates the pathogen by interacting with DNA, resulting in temporary inactivation, but may not kill the pathogen. Alternatively, the pathogen can be reactivated at a reactivation rate of about 10% per hour by exposure to normal white light. Therefore, UVC light with a wavelength of 254 nm can be ineffective in illuminated areas, such as in the internal cabin of a transporter. In addition, 254 nm UVC light is not recommended for human exposure. Because it can penetrate human cells. In contrast, sanitized UV light with a wavelength of 222 nm is safe for human exposure and kills pathogens. In addition, sanitized UV light with a wavelength of 222 nm can be emitted at full output of the UV lamp 120 within 1 millisecond or less after activation (in contrast, UVC with a wavelength of 254 nm has full output. It may take a few seconds or minutes to reach).

The sensor 178 may monitor the presence or absence of seat occupancy and / or the passenger's proximity to the UV lamp 124. For example, the first subset of sensors 178 may be configured to monitor the presence or absence of seat occupancy in order to determine the presence or absence of seat occupancy. The first subset may include pressure sensors, optical sensors, proximity sensors, cameras and the like. The pressure sensor may be integrated into the cushion or backrest to record changes in the sensor signal as the passenger sits in and out of the seat. Optical sensors can detect when light rays near the seat cushion are blocked. The blockage can occur when a person sits in a seat and gets up from the seat. Proximity sensors mounted on the seat may utilize infrared and / or microwave to identify when a person is present in the seat. The sensor 178 may generate a sensor signal to be transmitted to the control unit 170 at regular intervals periodically or in response to detection of change monitoring such as light blocking. The sensor signal can identify the source of the signal, such as an individual sensor that produces each of the signals. The control unit 170 receives a signal from the sensor 178 and analyzes the signal to determine whether or not each seat is occupied. In some embodiments, if a seat is determined to be vacant and unoccupied for at least a threshold amount of time (eg, 1 minute), the control unit 170 provides a UV side curtain for that seat. It is configured to reduce the output settings of one or more UV lamps 124. The output setting can be reduced to a lower setting, or the UV lamp (one or more) can be deactivated, at least until the sensor signal indicates that the seat is occupied. When the control unit 170 determines that both passengers in two adjacent seats are in the seat, the UV lamp 124 that emits UV light between the two adjacent seats is the air between the two passengers. Can be operated at high power or full power to be hygienic.

The second subset of sensors 178 may be configured to monitor passenger proximity to the UV lamp 124. The second subset may be proximity sensors mounted on or in close proximity to the UV lamp 124. Proximity sensors may use infrared or microwave to identify when a person is within a specified threshold proximity to UV lamp 124. The specified threshold proximity may be several inches, such as 2 inches, 4 inches, 6 inches, 8 inches, or 10 inches. Proximity sensors may be intended to focus on the proximity of objects in the UV light field, ignoring the proximity of the head of a person next to the UV lamp 124 but not in the field. The control unit 170 may reduce the output setting of the associated UV lamp 124 in response to receiving a signal indicating that a person has crossed near the threshold. The output setting may be reduced to a low setting or the UV lamp may be deactivated until the sensor signal indicates that the seat is occupied at least.

If the proximity thresholds are not crossed or the seat is not occupied, the control unit 170 will emit UV light continuously during the movement of the transporter to provide continued protection from pathogens. The lamp 124 can be controlled. Optionally, the control unit 170 may be configured to generally adjust the output setting of the UV lamp 124 based on various factors such as the level of activity in the cabin and the time of day. .. For example, the UV lamp 124 may be operated at high power or full power when passengers board and disembark the transporter. When the transporter is moving / cruising during the day, the control unit 170 may operate the UV lamp 124 in the medium power setting to save energy compared to the high power setting. The control unit 170 may operate the UV lamp 124 at a low setting when the transporter is moving / cruising at night. Most people are relatively inactive and are sleeping, reading, or watching videos. In addition, the intensity of UV irradiation can be increased to sterilize very quickly without excessive human exposure. The control operation followed by the control unit 170 may be stored in the memory 184.

The UV light shielding system 100 disclosed herein can sanitize the air entering a sealed passenger space without directly illuminating the passenger with UV light. UV lamps are placed primarily to provide protection for the protected person's face and upper body. Reflectors can be used to direct most of the UV to the unoccupied space on either side of the passenger and a small amount of UV to the passenger himself. The UV lamp can be placed on the top of the seat in front of the passenger or on the backrest. Sensors can be used to adjust the UV output and duty cycle when the passenger is in the immediate range of the UV lamp.

As described herein, the embodiments of the subject matter of the present disclosure use UV light without harming people exposed to UV light, the surface, air, and ( Provide systems and methods for sanitizing and sterilizing people (especially in passenger seats). Further, the embodiments of the subject matter of the present disclosure provide an air hygiene shield produced via UV light. UV shields are provided on one or both sides of the passenger in the seat, similar to side curtains or stalls, before air reaches the passenger and / or air from the passenger zone to another person or surface. Make the air hygienic before it reaches.
