BACKGROUND
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] As well known in the art, infectious disease transmission is a significant personal and public health concern. When common and potentially serious viral (e.g. Influenza), bacterial, and fungal pathogens come in contact with a surface, the surface gets contaminated and infected and thus viral, bacterial, and fungal pathogens are spread from mutually contacted surfaces. Commercial aircrafts currently use extensive on-board air filtration and other different technologies to decrease airborne microbes, yet disease transmission continues.
[0004] UV radiation source has been employed for disinfection and decontamination of surfaces, air, and liquids. It is considered to be one of the best non-contact decontamination processes. However, based on contemporarily available technology, it is difficult to increase the length and/or illuminance power of UV lamps.
[0005] There is therefore a need in the art for an improved disinfection device, which overcomes above-mentioned and other limitations of existing approaches.
[0006] All publications herein are incorporated by reference to the same extent as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
[0007] In some embodiments, the numbers expressing quantities of ingredients, properties such as concentration, reaction conditions, and so forth, used to describe and claim certain embodiments of the invention are to be understood as being modified in some instances by the term “about.” Accordingly, in some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable. The numerical values presented in some embodiments of the invention may contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

[0010] Another object of the present disclosure is to provide an improved disinfection device that is cost-effective and easy to implement.
[0011] Another object of the present disclosure is to provide a disinfection device with a horizontal member whose height can be adjusted to a particular level depending upon location of a surface to be disinfected.
[0012] Still another object of the present disclosure is to provide an improved disinfection device that can disinfect the surface automatically by moving in forward and backward direction.

[0055] FIGs. 2A and 2B illustrate exemplary representations of a disinfection device with a horizontal member in folded position, in accordance with embodiments of the present disclosure. As illustrated, the horizontal member 103 may be folded such that the second segment slides inside the first segment. The first segment with the folded second segment may be moved towards the side surface of the body such that the first segment can be fitted to a receptacle configured in the body. As illustrated, the disinfection device 100 may include another set of UV lamps 106 positioned at the side surface of the body. In another embodiment, the disinfection device 100 may include a set of UV lamps 113 that may be configured at the bottom of the body. In an example, the disinfection device 100 may include the set of UV lamps 106 may disinfect the surface at side areas of the aircraft whereas the set of UV lamps 113 may disinfect or decontaminate the surface of a floor.
[0056] FIGs. 3A and 3B illustrate exemplary representations of a disinfection device implemented in aircraft for disinfection, in accordance with embodiments of the present disclosure. FIGs. 3A and 3B show the aircrafts 300 with two seaters and three seaters configurations, respectively. The disinfection device 100 may be implemented in the aircraft for disinfecting one or more surfaces of the aircraft. In a particular embodiment, the device 100 may be implemented for disinfecting and decontaminating the seat surface, floor of the aircraft, luggage cabinet, and so on. In an embodiment, the UV lamps may be positioned at various parts of the device such as on horizontal member, vertical member, and side surface and bottom of the body to disinfect different types of surfaces of the aircraft.
[0057] In an embodiment, the device 100 may be charged at a particular level so that there may not be need for recharging the battery before completion of the process of disinfecting. In an embodiment, the disinfection device 100 may be driven to an aisle of the aircraft using a remote control mechanism. At this stage, the horizontal members may be positioned in a folded position in which the two horizontal members may be fitted to the side surfaces of the body. With the controlling of the second set of motors, the height of the vertical member may be adjusted such that the UV radiation from the UV lamps can easily fall on various surfaces of the aircraft. Upon adjusting the height of the vertical member, the horizontal member may be allowed to expand by moving away from the side surfaces. Then the second segment may be slided to expand the entire horizontal member. The expansion of the second segment over the first segment may be required when there is a large surface area to be disinfected. Thus, the disinfection device 100 can be accommodated for different types of seating configurations. Upon fixing the horizontal member depending on the surface area, the UV lamps may be switched on, which results in emitting of UV radiation on surfaces such as seat 302 as shown in FIGs. 3A and 3B. The emitting of UV radiation on the surface may lead to disinfection and decontamination of the UV radiation source.
