Patent Description:
Vehicles such as commercial aircraft are used to transport passengers between various locations. Systems are currently being developed to disinfect or otherwise sanitize surfaces within aircraft, for example, that use ultraviolet (UV) light. In order to sanitize a surface of a structure, a known UV light sterilization method emits a broad spectrum UVC light onto the structure.

Known UV light sanitizing systems are typically configured for a particular application. As an example, a UV light sanitizing system emits UV light at a particular wavelength in order to sanitize a surface.

However, in certain settings, a different type of wavelength of UV light may be desired. Accordingly, a different UV lamp that emits UV light at a different wavelength is typically used.

<CIT>, in accordance with its abstract, states a portable UV sterilizing device comprising: a substrate having a UV LED mounted thereon; a housing for accommodating the substrate; an optic for adjusting a diffusion angle of ultraviolet rays irradiated from the UV LED; and a connector electrically connected with the substrate, and serving as a route provided with electrical power from the outside. Moreover, this document provides a portable UV disinfecting device comprising: a substrate having a UV LED mounted thereon; a housing for accommodating the substrate; an optic for adjusting a diffusion angle of ultraviolet rays irradiated from the UV LED; and a battery electrically connected with the substrate, accommodated in the housing, and supplying electrical power to the UV LED.

<CIT>, in accordance with its abstract, states a sterilization apparatus configured to irradiate a sterilization target organism on a body or in the body with light and thereby killing or inactivating the sterilization target organism. The sterilization apparatus includes: a light source configured to emit light having wavelengths within a wavelength range of <NUM> to <NUM> and a wavelength range of <NUM> to <NUM>; a power supply unit configured to supply power to the light source; a control unit configured to control the power supply unit; and an optical filter. The power supply unit is controlled by the control unit so that an irradiation amount of light having a wavelength within the wavelength range of <NUM> to <NUM> in one light irradiation is not more than <NUM> mJ/cm2.

<CIT>, in accordance with its abstract, states an instrument for ultraviolet irradiation equipped with a plurality of light-shielding filters, each having different transmittances for ultraviolet ray emitted from a light source for irradiating a skin with ultraviolet radiation and a support member for supporting the light-shielding filters.

A need exists for a system and a method for adapting a UV light sanitizing system. Further, a need exists for a UV light sanitizing system and method that can be used with respect to various different applications.

With those needs in mind, certain examples of the present disclosure provide an adaptable sanitizing system including a sanitizing head including an ultraviolet (UV) lamp configured to emit UV light. One or more adapter modules are configured to removably couple to the sanitizing head at a coupling interface. The one or more adapter modules are configured to provide a functionality in relation to the UV light emitted by the UV lamp. For example, the functionality includes one of optical filtering, optical wavelength converting, fluid sanitizing, or object sanitizing.

In at least one example, the one or more adapter modules include a first adapter module configured to perform a first unique functionality, and a second adapter module configured to perform a second unique functionality that differs from.

As described herein, examples of the present disclosure provide an adaptable sanitizing system including one or more adapter modules that are configured to removably couple to a sanitizing head having an ultraviolet (UV) lamp, which is configured to emit UV light. The adapter modules are configured to provide functionality in relation to the UV light emitted by the UV lamp. For example, the adapter modules are configured to filter UV light. The adapter modules can be used to disinfect one or more of the following: skin or wounds of individuals, surfaces of objects (such as tools and equipment), fluid, such as air or water, and/or the like.

The phrase or term "adapter module" is intended to mean a device or assembly or the like that is attachable and/or removable to a sanitizing head, for example, and assist and/or compliment a UV disinfection or sanitizing process.

<FIG> illustrates a schematic block diagram of an adaptable sanitizing system <NUM>, according to an example of the present disclosure. The sanitizing system <NUM> includes a sanitizing head <NUM> and a plurality of adapter modules <NUM> that are configured to removably attach to the sanitizing head <NUM> at a coupling interface <NUM>.

The sanitizing head <NUM> includes an ultraviolet (UV) lamp <NUM> that is configured to emit UV light. The sanitizing head <NUM> is configured for use without any of the adapter modules <NUM> secured thereto. For example, the sanitizing head <NUM> can be uncoupled from the adapter modules <NUM> and emit UV light onto a surface to disinfect the surface. In at least one example, the sanitizing head <NUM> is part of a portable, mobile platform. For example, the sanitizing head <NUM> is part of a wand assembly, as described herein. The wand assembly can be coupled to a backpack assembly, a case assembly, a cart assembly, or the like. As another example, the wand assembly can be a standalone unit that is not coupled to another assembly, such as a backpack assembly.

Each adapter module <NUM> is configured to removably secure (that is, quickly attach to, and detach from) the sanitizing head <NUM> at the coupling interface <NUM>. As examples, the coupling interface <NUM> can include a track(s), a latch(es), a detent(s), an interference fit, a spring-biased coupling, an integral or separate fastener(s), and/or the like. In at least one example, the coupling interface <NUM> is common to all of the adapter modules <NUM>. That is, the coupling interface <NUM> may be the same for all of the adapter modules <NUM>.

The adapter modules <NUM> are configured to provide a functionality in relation to the UV light emitted from the UV lamp <NUM>. Each of the adapter modules <NUM> can provide a different functionality from the others. Examples of the functionalities include optical filtering, optical wavelength converting, fluid sanitizing, object sanitizing, and/or the like.

As an example, at least one of the adapter modules <NUM> is an optical filter that is configured to optically filter the UV light so as to ensure that certain undesired wavelengths of the UV light are not emitted through the first adapter module <NUM>. In this manner, the first adapter module <NUM> ensures that only UV light at a desired wavelength is emitted from the UV lamp <NUM> and through the first adapter module <NUM>. As an example, the first adapter module <NUM> includes an optical filter, such as a low pass optical filter that filters out light above <NUM> nanometers (nm).

As another example, at least one of the adapter modules <NUM> is an optical converter that is configured to convert UV light emitted from the UV lamp <NUM> at a first wavelength to a second wavelength. For example, the adapter module <NUM> is configured to up-convert or down-convert the UV light emitted from the UV lamp <NUM>.

As another example, at least one of the adapter modules <NUM> is a fluid sanitizer that is configured to disinfect a fluid stream passing therethrough via the UV light emitted from the UV lamp <NUM>. For example, the adapter module <NUM> is configured to allow a gas (such as air) or a liquid (such as water) to pass through an internal channel. The UV light emitted from the UV lamp <NUM> disinfects the fluid as it passes through the internal channel.

As another example, at least one of the adapter module <NUM> is an object sanitizer that is configured to disinfect an object (such as a utensil, tool, ball, and/or the like) disposed within a chamber therein. In at least one example, the chamber may be configured to allow a portion of human anatomy, such as a hand, to be disposed therein. The UV light emitted by the UV lamp is configured to disinfect the portion of human anatomy.

Each of the adapter modules <NUM> can be configured for a different, unique functionality, such as optical filtration, optical wavelength conversion, fluid sanitation, object sanitation, and/or the like. For example, a first adapter module <NUM> includes an optical filter, a second adapter module <NUM> includes a wavelength converter, a third adapter module <NUM> includes a fluid sanitizer, a fourth adapter module <NUM> includes an object sanitizer, and/or the like. Each of the adapter module <NUM> is interchangeable and is configured to removably attach, secure, or otherwise coupled to the sanitizing head <NUM> at the coupling interface <NUM>. In this manner, the sanitizing system <NUM> can be adapted to perform various different functions via the different adapter modules <NUM>. The sanitizing system <NUM> can include more or less adapter modules <NUM> than shown.

As descried herein, the adaptable sanitizing system <NUM> includes the sanitizing head <NUM> including the UV lamp <NUM> configured to emit UV light. One or more adapter modules <NUM> are configured to removably couple to the sanitizing head <NUM> at the coupling interface <NUM>. The adapter modules <NUM> are configured to provide a functionality (for example, optical filtering, optical wavelength converting, fluid sanitizing/disinfecting, object disinfecting, and/or the like) in relation to the UV light emitted by the UV lamp <NUM>. For example, a first adapter module <NUM> is configured to perform a first unique functionality (such as optical filtering), and a second adapter module <NUM> configured to perform a second unique functionality (such as fluid sanitizing/disinfecting) that differs from the first unique functionality.

<FIG> illustrates a flow chart of an adaptable sanitizing method, according to an example of the present disclosure. Referring to <FIG> and <FIG>, the method begins at <NUM>, at which the sanitizing head <NUM> having the UV lamp <NUM> is provided. The sanitizing head <NUM> does not include any of the adapter modules <NUM>. The sanitizing head <NUM> is configured to emit the UV light at a particular wavelength, such as within the far UV spectrum (for example, between <NUM>-<NUM>), the UVC spectrum (such as between <NUM>-<NUM>), and/or the like.

At <NUM>, it is determined if use of the sanitizing head <NUM> is to be adapted (for example, changed). That is, it is determined if the particular use for which the sanitizing head <NUM> is configured is to be changed. For example, the sanitizing head <NUM> can be configured to sanitize a surface of an object at a particular wavelength, such as <NUM>, <NUM>, or the like. The method may then return to <NUM>. If the use is not to be adapted at <NUM>, the method proceeds to <NUM>, at which the sanitizing head <NUM> is operated without any adapter module <NUM> coupled thereto.

If, however, it is determined that the use of sanitizing head <NUM> is to be adapted at <NUM>, the method proceeds to <NUM>, at which a first adapter module <NUM> (configured for a desired functionality) is attached to the sanitizing head <NUM>. Next, the sanitizing head <NUM> is operated at <NUM> to achieve the desired functionality via the first adapter module <NUM>.

At <NUM>, it is determined if the use of the sanitizing head <NUM> coupled to the first adapter module <NUM> is to be adapted (for example, changed). If not, the method returns to <NUM>.

If, however, the use of the sanitizing head <NUM> coupled to the first adapter module <NUM> is to be adapted, the method proceeds to <NUM>, at which the first adapter module <NUM> is removed from the sanitizing head <NUM>. The method may then return to <NUM>. Optionally, the method may proceed to <NUM>, at which a second adapter module <NUM>, which is configured for a functionality that differs from the first adapter module <NUM>, is attached to the sanitizing head <NUM>. The method then repeats in a similar fashion.

<FIG> illustrates a simplified view of the coupling interface <NUM> between the sanitizing head <NUM> and the adapter module <NUM>, according to an example of the present disclosure. For example, the coupling interface <NUM> includes one or more tracks <NUM> within a housing, body, or shroud of the sanitizing head <NUM> into which one or more reciprocal members <NUM> (such as ridges, tabs, ledges, fins, and/or the like) of the adapter module <NUM> are configured to slide. Optionally, the sanitizing head <NUM> includes the reciprocal members <NUM>, and the adapter module <NUM> includes the track(s) <NUM>. In at least one example, the coupling interface <NUM> is common to all of the adapter modules <NUM>, such as shown in <FIG>.

<FIG> illustrates a simplified view of the coupling interface <NUM> between the sanitizing head <NUM> and the adapter module <NUM>, according to an example of the present disclosure. For example, the coupling interface <NUM> includes one or more latches <NUM> secured to a housing, body, or shroud of the sanitizing head <NUM>. The latches <NUM> are configured to secure into and release from reciprocal members <NUM> (such as openings, protuberances, or the like) of the adapter module <NUM>. Optionally, the sanitizing head <NUM> includes the reciprocal members <NUM>, and the adapter module <NUM> includes the latch(es) <NUM>. In at least one example, the coupling interface <NUM> is common to all of the adapter modules <NUM>, such as shown in <FIG>.

<FIG> illustrates a simplified view of the coupling interface <NUM> between the sanitizing head <NUM> and the adapter module <NUM>, according to an example of the present disclosure. For example, the coupling interface <NUM> includes hook and loop fasteners <NUM> (for example, Velcro) secured to a housing, body, or shroud of the sanitizing head <NUM>. The hook and loop fasteners <NUM> are configured to secure to and release from reciprocal hook and loop fasteners <NUM>. For example, the hook and loop fasteners <NUM> are secured to exposed lower surfaces of the sanitizing head <NUM>, and the hook and loop fasteners <NUM> are secured to upper surfaces of the adapter module <NUM>. In at least one example, the coupling interface <NUM> is common to all of the adapter modules <NUM>, such as shown in <FIG>.

<FIG> illustrates a simplified view of the coupling interface <NUM> between the sanitizing head <NUM> and the adapter module <NUM>, according to an example of the present disclosure. For example, the coupling interface <NUM> includes one or more through-holes <NUM> secured to a housing, body, or shroud of the sanitizing head <NUM>. One or more deflectable spring arms <NUM> of the adapter module <NUM> have distal ends <NUM> that are configured to deflect into (for example, snap into) the through-holes <NUM>. The latches <NUM> are configured to secure into and release from reciprocal members <NUM> (such as openings, protuberances, or the like) of the adapter module <NUM>. Optionally, the sanitizing head <NUM> includes the deflectable spring arms <NUM> and the adapter module <NUM> includes the through-holes <NUM>. In at least one example, the coupling interface <NUM> is common to all of the adapter modules <NUM>, such as shown in <FIG>.

<FIG> illustrates a simplified view of the coupling interface <NUM> between the sanitizing head <NUM> and the adapter module <NUM>, according to an example of the present disclosure. For example, the coupling interface <NUM> includes a surface <NUM> that is configured to fit into an opening <NUM> of the sanitizing head <NUM> through an interference fit and/or plug and socket connection. Optionally, the sanitizing head <NUM> includes the surface <NUM>, and the adapter module <NUM> includes the opening <NUM>. In at least one example, the coupling interface <NUM> is common to all of the adapter modules <NUM>, such as shown in <FIG>.

<FIG> illustrates a simplified view of the coupling interface <NUM> between the sanitizing head <NUM> and the adapter module <NUM>, according to an example of the present disclosure. For example, the coupling interface <NUM> includes one or more integral fasteners <NUM> (such as quarter turn, half turn, or the like bayonet-type fasteners) that are configured to mate with reciprocal cavities <NUM> formed in the adapter module <NUM>. Optionally, the sanitizing head <NUM> includes the cavities <NUM>, and the adapter module <NUM> includes the fasteners <NUM>. In at least one example, the coupling interface <NUM> is common to all of the adapter modules <NUM>, such as shown in <FIG>.

<FIG> illustrates a perspective bottom view of the adaptable sanitizing system <NUM>, according to an example of the present disclosure. The adaptable sanitizing system <NUM> includes the sanitizing head <NUM>, and the adapter module <NUM>, which is removably coupled to the sanitizing head <NUM>, as described herein. In at least one example, the adapter module <NUM> includes a shroud <NUM> that removably secures to a shroud <NUM> of the sanitizing head <NUM> at the coupling interface <NUM>. The shroud <NUM> retains an optical filter <NUM>. Referring to <FIG> and <FIG>, UV light emitted by the UV lamp <NUM> is emitted toward the optical filter <NUM>, which filters light at predetermined wavelengths from the emitted UV lamp <NUM>, thereby ensuring that filtered UV light <NUM> passes out of the optical filter <NUM>.

Referring to <FIG> and <FIG>, the adapter module <NUM> is distinct from the sanitizing head <NUM>. That is, the sanitizing head <NUM> does not include the adapter module <NUM>, or vice versa. Rather, the adapter module <NUM> is configured to removably couple to (for example, connect to, and disconnect from) the sanitizing head <NUM>. The sanitizing head <NUM> is operative (such as to emit UV light) whether or not the adapter module <NUM> is secured to the sanitizing head <NUM>.

As an example, the UV lamp <NUM> is configured to emit UV light at a particular wavelength, such as within the far UV spectrum (for example, <NUM>). However, the UV light emitted by the UV lamp <NUM> may still include light at longer wavelengths, such as beyond <NUM>. Accordingly, in at least one example, the optical filter <NUM> is a <NUM> low pass filter that filters light above <NUM>, thereby ensuring that light having a wavelength shorter than <NUM> passes through and out of the optical filter <NUM>. As an example, the optical filter <NUM> filters the UV light emitted by the UV lamp <NUM>, thereby providing the UV light <NUM> that passes through and out of the optical filter <NUM> at a wavelength of <NUM>, which neutralizes (such as kills) microbes (for example, viruses and bacteria), while posing no risk to humans.

As can be appreciated, however, the optical filter <NUM> attenuates or otherwise causes a loss of power from the UV light as it passes therethrough. As such, if more power is desired, and if there is no risk to human exposure, the adapter module <NUM> can be removed from the sanitizing head <NUM>, which may then emit the UV light at a higher, unfiltered power. The adapter module <NUM> can be selectively connected to, and removed from, the sanitizing head <NUM> as desired.

As described, in at least one example, the sanitizing system <NUM> includes the adapter module <NUM> having the optical filter <NUM>. The adapter module <NUM> can be selectively coupled to an uncoupled from the sanitizing head <NUM>. The sanitizing system <NUM> can be used without the adapter module <NUM> to emit UV light onto surfaces, when there is little to no risk of human exposure. If, however, the potential for human exposure exists, the adapter module <NUM> can be coupled to the sanitizing head <NUM> so that the optical filter <NUM> efficiently filters undesired wavelengths of UV light.

<FIG> illustrates a cross-sectional view of the adapter module <NUM> through line <NUM>-<NUM> of <FIG>. In at least one example, the optical filter <NUM> is a panel <NUM> that secures to the shroud <NUM>. In at least one other example, the entire adapter module <NUM> can be or otherwise include a homogenous optical filter <NUM>. For example, the adapter module <NUM> can be formed of the material of the optical filter <NUM>. In at least one example, the shroud <NUM> and the optical filter <NUM> are formed of the same, light filtering material.

In at least one example, the optical filter <NUM> is formed of silicon. The optical filter <NUM> can be doped with a metallic coating and/or etched in a particular pattern to filter UV light at a predetermined wavelength. As noted, the optical filter <NUM> can be a <NUM> low pass filter that is configured to filter wavelengths above <NUM> from the UV light emitted by the UV lamp <NUM>. Optionally, the optical filter <NUM> can be configured to filter wavelengths higher or lower than <NUM>. For example, the optical filter <NUM> can be configured to filter wavelengths other than <NUM> from the UV light emitted by the UV lamp <NUM>.

<FIG> illustrates a perspective bottom view of an adaptable sanitizing system <NUM> having the adapter module <NUM> separated from the sanitizing head <NUM>, according to an example of the present disclosure. In at least one example, the adapter module <NUM> includes a frame <NUM> that retains the optical filter <NUM> therebetween. The frame <NUM> is configured to removably couple to an exposed lower perimeter <NUM> of the shroud <NUM> of the sanitizing head <NUM> via a coupling interface <NUM>, such as any of those described herein.

Referring to <FIG> and <FIG>, an adapter module <NUM> is configured to removably couple to the sanitizing head <NUM> having the UV lamp <NUM> that is configured to emit UV light. The adapter module includes the shroud <NUM> or the frame <NUM> that is configured to removably couple to the sanitizing head <NUM> at the coupling interface <NUM>. The optical filter <NUM> is coupled to the shroud <NUM> or the frame <NUM>. The optical filter <NUM> is configured to filter the UV light emitted by the UV lamp <NUM>.

<FIG> illustrates a schematic block diagram of an adapter module <NUM>, according to an example of the present disclosure. As shown, the adapter module <NUM> includes a shroud <NUM>. The shroud <NUM> includes an inlet <NUM> and an outlet <NUM> in fluid communication with a fluid passage <NUM> within the shroud <NUM>. The fluid passage <NUM> can be defined by internal surfaces <NUM> of the shroud <NUM>. In at least one example, the internal surfaces <NUM> are reflective. For example, the internal surfaces <NUM> are coated and/or covered with mirrors or other such reflectors (such as Teflon, Porex, polished aluminum, and or the like).

In operation, fluid (such as a gas or liquid) enters the shroud through the inlet <NUM> and passes through the fluid passage <NUM>. Referring to <FIG> and <FIG>, UV light emitted by the UV lamp <NUM> is emitted into the fluid passage <NUM>, thereby disinfecting the fluid. The disinfected fluid then passes out of the outlet <NUM>.

The reflective surfaces <NUM> reflect the UV light back into the fluid passage <NUM>. Further, the sanitizing head <NUM> can also include internal reflective surfaces, thereby ensuring that the emitted UV light continually reflects into the fluid passage <NUM> (with no or reduced absorption), which increases the efficiency of the sanitizing/disinfecting operation. Alternatively, the adapter module <NUM> may not include reflective surfaces.

In at least one example, a particulate filter <NUM> is disposed within the fluid passage <NUM>. For example, the particulate filter <NUM> is disposed at or proximate to the inlet <NUM>. The particulate filter <NUM> removes particulates (such as dust, debris, or other impurities) from the fluid, whether gas or liquid. Particulates could otherwise cause shadowing in relation to the UV light. As such, the particulate filter <NUM> increases the effectiveness and efficiency of the sanitation process. Alternatively, the adapter module <NUM> does not include the particulate filter.

In at least one example, an ozone filter <NUM> is disposed within the fluid passage <NUM>. For example, the ozone filter <NUM> is disposed at or proximate to the outlet <NUM>. The ozone filter <NUM> removes ozone (such as may be generated by the UV light interacting with the fluid stream) from the fluid stream. Alternatively, the adapter module <NUM> does not include the ozone filter.

Referring to <FIG> and <FIG>, an adapter module <NUM> is configured to removably couple to the sanitizing head <NUM> having the UV lamp <NUM> that is configured to emit UV light. The adapter module <NUM> includes the shroud <NUM> that is configured to removably couple to the sanitizing head <NUM> at the coupling interface <NUM>. The fluid passage <NUM> in fluid communication with the inlet <NUM> and the outlet <NUM> is within the shroud <NUM> (such as within an internal chamber <NUM> defined by the shroud <NUM>. Fluid (such as a gas or liquid) passes into the fluid passage <NUM> through the inlet <NUM> and passes out of the outlet <NUM>. The UV light is emitted by the UV lamp <NUM> into the fluid passage <NUM> as the fluid passes through the fluid passage <NUM> between the inlet <NUM> and the outlet <NUM>.

<FIG> illustrates a perspective view of the sanitizing system <NUM> having the adapter module <NUM> uncoupled from the sanitizing head <NUM>, according to an example of the present disclosure. <FIG> illustrates a perspective view of the sanitizing system <NUM> of <FIG> having the adapter module <NUM> coupled to the sanitizing head <NUM>. Referring to <FIG>, the shroud <NUM> of the adapter module <NUM> can define the fluid passage <NUM>. In at least one other example, one or more tubes <NUM> (such as formed of glass) can define the fluid passage <NUM>.

<FIG> illustrates a perspective top view of the adapter module <NUM>, according to an example of the present disclosure. <FIG> illustrates a top view of the fluid passage <NUM>, according to an example of the present disclosure. <FIG> illustrates an internal view of the sanitizing system <NUM>. Referring to <FIG>, as shown, the adapter module <NUM> includes a tube <NUM> having a plurality of straight segments <NUM>, <NUM>, and <NUM> connected by bends <NUM> and <NUM>, thereby providing a long, circuitous path for fluid to travel within the adapter module <NUM>. The fluid can be a gas (such as air), or liquid (such as water).

In at least one example, a blower <NUM>, such as a fan, is disposed within the adapter module <NUM> (such as within and/or on the shroud <NUM>). The blower <NUM> can be disposed at or proximate to (such as within <NUM> inches) the inlet <NUM>, for example. Optionally, the blower <NUM> can be disposed within the tube <NUM>. The blower <NUM> draws air from outside the adapter module <NUM> into the fluid passage <NUM>.

In at least one example, the tube <NUM> is formed of a transparent material, such as glass. It has been found that a glass tube <NUM> absorbs little to no UV light, thereby ensuring that the UV light emitted by the UV lamp <NUM> effectively and efficiently disinfects the fluid flowing through the fluid passage <NUM>, as defined by the tube <NUM>. The multiple segments <NUM>, <NUM>, and <NUM>, and bends <NUM> and <NUM> provided a relatively long, circuitous path for the fluid to travel, which extends the time the fluid is within the fluid passage <NUM>. The extended length of time of the fluid within the fluid passage <NUM> ensures a longer period of time of exposure to the UV light, which further increasing the sanitizing efficiency.

Optionally, the tube <NUM> may include more or less segments and bends than shown. For example, the tube <NUM> may include a single straight segment with no bends. As another example, the tube <NUM> may include four or more straight segments and three or more bends. As another example, multiple disconnected tubes <NUM> may be used.

<FIG> illustrate an internal view of the sanitizing system <NUM>, according to an example of the present disclosure. In this example, the adapter module <NUM> does not include a tube. Instead, the fluid passage <NUM> is defined by internal surfaces <NUM> (whether or not reflective) of the shroud <NUM>.

<FIG> illustrates a perspective view of the sanitizing system <NUM> coupled to a breathing mask <NUM>, according to an example of the present disclosure. The sanitizing head <NUM> can be part of a wand assembly <NUM> that couples to a backpack assembly <NUM>. The adapter module <NUM> is configured to sanitize fluid, such as described with respect to <FIG>. A first end <NUM> of a hose or tube <NUM> connects to the outlet <NUM>. A second end <NUM> of the tube <NUM> connects to an inlet <NUM> of the breathing mask <NUM>. As such, the sanitizing system <NUM> is configured, by way of the adapter module <NUM>, to sanitize air, and deliver the clean, sanitized air to the breathing mask <NUM>, which can be worn by an individual. The sanitizing system <NUM> and the breathing mask <NUM> can be used by an individual in a setting that may be susceptible to airborne pathogens, such as within a pandemic or epidemic zone.

<FIG> illustrates a side view of a sanitizing system <NUM>, according to an example of the present disclosure. In this example, the sanitizing system <NUM> can be disposed at a location, such as within an internal cabin of a vehicle, a room, or the like. The blower <NUM> draws air into the adapter module <NUM>. The air passes through the fluid passage <NUM>, as described with respect to <FIG>. UV light emitted by the UV lamp <NUM> sanitizes the air as it passes through the fluid passage <NUM>. The clean, sanitized air <NUM> is then passed out of the outlet <NUM> into the location.

<FIG> illustrates a side view of a sanitizing system <NUM>, according to an example of the present disclosure. In this example, an outlet 184a of a first adapter module 104a (coupled to a first sanitizing head 102a) is in fluid communication with an inlet 182b of a second adapter module 104b (coupled to a second sanitizing head 102b). In this manner, air that enters the inlet 182a of the first adapter module 104a is initially sanitized, and the initially sanitized air passes out of the outlet 184a into the inlet 182b of the second adapter module 104b, where it is further sanitized, and ultimately passes out of the outlet 184b into the location. As such, multiple adapter modules <NUM> can be linked together in series to provide highly sanitized air. The sanitizing system <NUM> can include more sanitizing heads and adapter modules than shown. The sanitizing head 102a may be coupled to a first backpack assembly 204a, and the sanitizing head 102b may be coupled to a second backpack assembly 204b.

<FIG> illustrates a side view of a sanitizing system, <NUM> according to an example of the present disclosure. Referring to <FIG> and <FIG>, in at least one example, the fluid passage <NUM> can be configured to channel liquid, such as water. The adapter module <NUM> includes a valve <NUM> and pump <NUM> at or proximate to the inlet <NUM>. A liquid inlet line <NUM> is connected to the valve <NUM>, the pump <NUM>, and/or the inlet <NUM>. The valve <NUM> controls flow of the liquid into the fluid passage <NUM>. The pump <NUM> moves the liquid through the fluid passage <NUM>. The UV lamp <NUM> emits UV light into the fluid passage <NUM> as the liquid flows therethrough, thereby sanitizing the liquid as it flows through the fluid passage <NUM>. Clean, sanitized liquid, such as may be suitable for drinking, flows out of the outlet <NUM>, such as into an outlet hose <NUM>. Optionally, the adapter module <NUM> may not include the valve <NUM> and/or the pump <NUM>.

<FIG> illustrates a perspective view of a portable sanitizing system <NUM> worn by an individual <NUM>, according to an example of the present disclosure. The portable sanitizing system <NUM> includes a wand assembly <NUM> coupled to a backpack assembly <NUM> that is removably secured to the individual through a harness <NUM>. The wand assembly <NUM> includes a sanitizing head <NUM> coupled to a handle <NUM>. In at least one example, the sanitizing head <NUM> is moveably coupled to the handle <NUM> through a coupler <NUM>.

The sanitizing head <NUM> is an example of the sanitizing head <NUM> shown and described with respect to <FIG>. Adapter modules <NUM> can be removably coupled to the sanitizing head <NUM>, as described above.

In at least one other example, the portable sanitizing system <NUM> may not be worn by the individual <NUM>. For example, the portable sanitizing system <NUM> may include a case assembly that is configured to be opened and closed. The case assembly may store the wand assembly <NUM> when not in use. The case assembly may be opened to allow the wand assembly <NUM> to be removed and operated.

As shown in <FIG>, the wand assembly <NUM> is in a stowed position. In the stowed position, the wand assembly <NUM> is removably secured to a portion of the backpack assembly <NUM>, such as through one or more tracks, clips, latches, belts, ties, and/or the like.

In at least one other example, the wand assembly <NUM> is stored within a case assembly in a stowed position. For example, the wand assembly <NUM> in the stowed position is contained within a closed case assembly. The case assembly may be opened to allow the wand assembly <NUM> to be removed and deployed.

<FIG> illustrates a perspective lateral top view of the wand assembly <NUM>, according to an example of the present disclosure. The sanitizing head <NUM> couples to the handle <NUM> through the coupler <NUM>. The sanitizing head <NUM> includes a shroud <NUM> having an outer cover <NUM> that extends from a proximal end <NUM> to a distal end <NUM>. As described herein, the shroud <NUM> contains a UV lamp.

Optionally, the wand assembly <NUM> may include the sanitizing head <NUM> connected to a fixed handle. Further, the wand assembly <NUM> may be sized and shaped differently than shown.

A port <NUM> extends from the proximal end <NUM>. The port <NUM> couples to a hose <NUM>, which, in turn, couples to the backpack assembly <NUM> (shown in <FIG>). The hose <NUM> contains electrical cords, cables, wiring, or the like that couples a power source or supply (such as one or more batteries) within the backpack assembly <NUM> (shown in <FIG>) to a UV lamp <NUM> within the shroud <NUM>. Optionally, the electrical cords, cables, wiring, or the like may be outside of the hose <NUM>. In at least one example, the hose <NUM> also contains an air delivery line, such as an air tube) that fluidly couples an internal chamber of the shroud <NUM> to an air blower, vacuum generator, air filters, and/or the like within the backpack assembly <NUM>.

The coupler <NUM> is secured to the outer cover <NUM> of the shroud <NUM>, such as proximate to the proximal end <NUM>. The coupler <NUM> may include a securing beam <NUM> secured to the outer cover <NUM>, such as through one or more fasteners, adhesives, and/or the like. An extension beam <NUM> outwardly extends from the securing beam <NUM>, thereby spacing the handle <NUM> from the shroud <NUM>. A bearing assembly <NUM> extends from the extension beam <NUM> opposite from the securing beam <NUM>. The bearing assembly <NUM> includes one or more bearings, tracks, and/or the like, which allow the handle <NUM> to linearly translate relative to the coupler <NUM> in the directions of arrows A, and/or pivot about a pivot axle in the directions of arc B. Optionally, the securing beam <NUM> may include a bearing assembly that allows the sanitizing head <NUM> to translate in the directions of arrows A, and/or rotate (for example, swivel) in the directions of arc B in addition to, or in place of, the handle <NUM> being coupled to the bearing assembly <NUM> (for example, the handle <NUM> may be fixed to the coupler <NUM>).

In at least one other example, the wand assembly <NUM> does not include the coupler <NUM>. Instead, the handle <NUM> may be fixed to the shroud <NUM>, for example.

In at least one example, the handle <NUM> includes a rod, pole, beam, or the like <NUM>, which may be longer than the shroud <NUM>. Optionally, the rod <NUM> may be shorter than the shroud <NUM>. One or more grips <NUM> are secured to the rod <NUM>. The grips <NUM> are configured to be grasped and held by an individual. The grips <NUM> may include ergonomic tactile features <NUM>.

Optionally, the wand assembly <NUM> can be sized and shaped differently than shown. For example, in at least one example, the handle <NUM> can be fixed in relation to the shroud <NUM>. Further, the handle <NUM> may not be configured to move relative to itself and/or the shroud <NUM>. For example, the handle <NUM> and the shroud <NUM> can be integrally molded and formed as a single unit.

<FIG> illustrates a perspective rear view of the wand assembly <NUM> of <FIG>. <FIG> illustrates a perspective lateral view of the wand assembly <NUM> of <FIG>. Referring to <FIG>, the handle <NUM> may pivotally couple to the coupler <NUM> through a bearing <NUM> having a pivot axle <NUM> that pivotally couples the handle <NUM> to the coupler <NUM>. The handle <NUM> may further be configured to linearly translate into and out of the bearing <NUM>. For example, the handle <NUM> may be configured to telescope in and out. Optionally, or alternatively, in at least one example, the handle <NUM> may include a telescoping body that allows the handle <NUM> to outwardly extend and inwardly recede. In at least one other example, the handle <NUM> may not be configured to move, extend, retract, or the like relative to the shroud <NUM>.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> in a compact deployed position, according to an example of the present disclosure. The wand assembly <NUM> is removed from the backpack assembly <NUM> (as shown in <FIG>) into the compact deployed position, as shown in <FIG>. The hose <NUM> connects the wand assembly <NUM> to the backpack assembly <NUM>. In the compact deployed position, the sanitizing head <NUM> is fully retracted in relation to the handle <NUM>.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> having the sanitizing head <NUM> in an extended position, according to an example of the present disclosure. In order to extend the sanitizing head <NUM> relative to the handle <NUM>, the sanitizing head <NUM> is outwardly slid relative to the handle <NUM> in the direction of arrow A' (or the handle <NUM> is rearwardly slid relative to the sanitizing head <NUM>). As noted, the sanitizing head <NUM> is able to linearly translate in the direction of arrow A' relative to the handle <NUM> via the coupler <NUM>. The outward extension of the sanitizing head <NUM>, as shown in <FIG>, allows for the portable sanitizing system <NUM> to easily reach distant areas. Alternatively, the sanitizing head <NUM> may not linearly translate relative to the handle <NUM>.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> having the sanitizing head <NUM> in an extended position and the handle <NUM> in an extended position, according to an example of the present disclosure. To reach even further, the handle <NUM> may be configured to linearly translate, such as through a telescoping portion, to allow the sanitizing head <NUM> to reach further outwardly. Alternatively, the handle <NUM> may not be configured to extend and retract.

In at least one example, the handle <NUM> may include a lock <NUM>. The lock <NUM> is configured to be selectively operated to secure the handle <NUM> into a desired extended (or retracted) position.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> having the sanitizing head <NUM> rotated in relation to the handle <NUM>, according to an example of the present disclosure. As noted, the sanitizing head <NUM> is configured to rotate relative to the handle <NUM> via the coupler <NUM>. Rotating the sanitizing head <NUM> relative to the handle <NUM> allows the sanitizing head <NUM> to be moved to a desired position, and sweep or otherwise reach into areas that would otherwise be difficult to reach if the sanitizing head <NUM> was rigidly fixed to the handle <NUM>. Alternatively, the sanitizing head <NUM> may not be rotatable relative to the handle <NUM>.

<FIG> illustrates a perspective end view of a UV lamp <NUM> and a reflector <NUM> of the sanitizing head <NUM>, according to an example of the present disclosure. Again, the sanitizing head <NUM> is an example of the sanitizing head <NUM>, such as shown in <FIG>. Further, the UV lamp <NUM> is an example of the UV lamp <NUM>, such as shown in <FIG>.

The UV lamp <NUM> and the reflector <NUM> are secured within the shroud <NUM> (shown in <FIG>, for example) of the sanitizing head <NUM>. In at least one example, the reflector <NUM> is secured to an underside <NUM> of the shroud <NUM>, such as through one or more adhesives. As another example, the reflector <NUM> is an integral part of the shroud <NUM>. For example, the reflector <NUM> may be or otherwise provide the underside <NUM> of the shroud <NUM>. The reflector <NUM> provides a reflective surface <NUM> (such as formed of Teflon, a mirrored surface, and/or the like) that is configured to outwardly reflect UV light emitted by the UV lamp <NUM>. In at least one example, the shroud <NUM> may be or include a shell formed of fiberglass, and the reflector <NUM> may be formed of Teflon that provides a <NUM>% reflectivity. In at least one example, the reflector <NUM> may be a multi-piece reflector.

The reflector <NUM> may extend along an entire length of the underside <NUM> of the shroud <NUM>. Optionally, the reflector <NUM> may extend along less than an entire length of the underside <NUM> of the shroud <NUM>.

The UV lamp <NUM> may extend along an entire length (or along substantially the entire length, such as between the ends <NUM> and <NUM>). The UV lamp <NUM> is secured to the reflector <NUM> and/or the shroud <NUM> through one or more mounts, such as brackets, for example. The UV lamp <NUM> includes one or more UV light emitters, such as one more bulbs, light emitting elements (such as light emitting diodes), and/or the like. In at least one example, the UV lamp <NUM> is configured to emit UV light in the far UV spectrum, such as at a wavelength between <NUM> - <NUM>. In at least one example, the UV lamp <NUM> is configured to emit UV light having a wavelength of <NUM>. For example, the UV lamp <NUM> may be or include a <NUM> W bulb that is configured to emit UV light having a wavelength of <NUM>. Alternatively, the UV lamp <NUM> may be configured to emit UV light in other portions of the UV spectrum, such as the UVC spectrum.

As shown, the reflector <NUM> includes flat, upright side walls <NUM> connected together through an upper curved wall <NUM>. The upper curved wall <NUM> may be bowed outwardly away from the UV lamp <NUM>. For example, the upper curved wall <NUM> may have a parabolic cross-section and/or profile.

It has been found that the straight, linear side walls <NUM> provide desired reflection and/or focusing of UV light emitted from the UV lamp <NUM> toward and onto a desired location. Alternatively, the side walls <NUM> may not be linear and flat.

<FIG> illustrates a perspective end view of the UV lamp <NUM> and a reflector <NUM> of the sanitizing head, according to an example of the present disclosure. The reflector <NUM> shown in <FIG> is similar to the reflector <NUM> shown in <FIG>, except that the side walls <NUM> may outwardly cant from the upper curved wall <NUM>.

<FIG> illustrates a perspective end view of the UV lamp <NUM> and the reflector <NUM> of the sanitizing head, according to an example of the present disclosure. In this example, the side walls <NUM> may be curved according to the curvature of the upper curved wall <NUM>.

<FIG> illustrates a perspective top view of the sanitizing head <NUM>. <FIG> illustrates a perspective bottom view of the sanitizing head <NUM>. <FIG> illustrates an axial cross-sectional view of the sanitizing head <NUM> through line <NUM>-<NUM> of <FIG>. Referring to <FIG>, air <NUM> is configured to be drawn into the sanitizing head <NUM> through one or more openings <NUM> (or simply an open chamber) of the shroud <NUM>. The air <NUM> is drawn into the sanitizing head <NUM>, such as via a vacuum generator within the backpack assembly <NUM> (shown in <FIG>). The air <NUM> is drawn into the shroud <NUM>, and cools the UV lamp <NUM> as it passes over and around the UV lamp <NUM>. The air <NUM> passes into the port <NUM> and into the hose <NUM>, such as within an air tube within the hose <NUM>. The air <NUM> not only cools the UV lamp <NUM>, but also removes ozone, which may be generated by operation of the UV lamp <NUM>, within the shroud <NUM>. The air <NUM> may be drawn to an air filter, such as an activated carbon filter, within the backpack assembly <NUM>.

In at least one example, the portable sanitizing system <NUM> may also include an alternative ozone mitigation system. As an example, the ozone mitigation system may be disposed in the shroud <NUM> or another portion of the system, and may include an inert gas bath, or a face inert gas system, such as in <CIT>.

Referring to <FIG>, in particular, a bumper <NUM> may be secured to an exposed lower circumferential edge <NUM> of the shroud <NUM>. The bumper <NUM> may be formed of a resilient material, such as rubber, another elastomeric material, open or closed cell foam, and/or the like. The bumper <NUM> protects the sanitizing head <NUM> from damage in case the sanitizing head <NUM> inadvertently contacts a surface. The bumper <NUM> also protects the surface from damage.

The openings <NUM> may be spaced around the lower surface of the shroud <NUM> such that they do not provide a direct view of the UV lamp <NUM>. For example, the openings <NUM> may be positioned underneath portions that are spaced apart from the UV lamp <NUM>.

Referring to <FIG>, in particular, the sanitizing head <NUM> may include a cover plate <NUM> below the UV lamp <NUM>. The cover plate <NUM> may be formed of glass, for example, and may be configured to filter UV light emitted by the UV lamp <NUM>. The UV lamp <NUM> may be secured within an interior chamber <NUM> defined between the reflector <NUM> and the cover plate <NUM>. In at least one example, the cover plate <NUM> is or otherwise includes a far UV band pass filter. For example, the cover plate <NUM> may be a <NUM> band pass filter that filters UV light emitted by the UV lamp <NUM> to a <NUM> wavelength. As such, UV light that is emitted from the sanitizing head <NUM> may be emitted at a wavelength of <NUM>. The optical filter <NUM>, shown and described with respect to <FIG>, may be a <NUM> band pass filter.

Referring to <FIG>, a rim <NUM> (such as a <NUM>" thick Titanium rim) may connect the cover plate <NUM> to the shroud <NUM>. The rim <NUM> may distribute impact loads therethrough and/or therearound.

In at least one example, ranging light emitting diodes (LEDs) <NUM> may be disposed proximate to ends of the UV lamp <NUM>. The ranging LEDs <NUM> may be used to determine a desired range to a structure that is to be sanitized, for example. In at least one example, the ranging LEDs <NUM> may be disposed on or within the rim <NUM> and/or the cover plate <NUM>. As another example, the sanitizing head <NUM> may be configured for range guidance, as disclosed in <CIT>.

<FIG> illustrates a perspective end view of the UV lamp <NUM> secured to a mounting bracket or clamp <NUM>, according to an example of the present disclosure. Each end of the UV lamp <NUM> may be coupled to mounting bracket or clamp <NUM>, which secures the UV lamp <NUM> to the shroud <NUM> (shown in <FIG>). A buffer, such as a thin (for example, <NUM>") sheet of silicon may be disposed between the end of the UV lamp <NUM> and the bracket <NUM>. Optionally, the UV lamp <NUM> may be secured to the shroud <NUM> through brackets or clamps that differ in size and shape than shown. As another example, the UV lamp <NUM> may be secured to the shroud <NUM> through adhesives, fasteners, and/or the like.

<FIG> illustrates a perspective exploded view of the backpack assembly <NUM>, according to an example of the present disclosure. The backpack assembly <NUM> includes a front wall <NUM> that couples to a rear shell <NUM>, a base <NUM>, and a top cap <NUM>. An internal chamber <NUM> is defined between the front wall <NUM>, the rear shell <NUM>, the base <NUM>, and the top cap <NUM>. One or more batteries <NUM>, such as rechargeable Lithium batteries, are contained within the internal chamber <NUM>. An air generation sub-system <NUM> is also contained within the internal chamber <NUM>. The air generation sub-system <NUM> is in fluid communication with an air tube within the hose <NUM> (shown in <FIG>, for example). The air generation sub-system <NUM> may include an airflow device, such as a vacuum generator, an air blower, and/or the like. The airflow device is configured to generate airflow to cool the UV lamp, draw air from the sanitizing head <NUM> into the backpack assembly <NUM> and out through an exhaust, draw or otherwise remove generated ozone away from the shroud <NUM>, and/or the like.

One or more air filters <NUM>, such as carbon filters, are within the backpack assembly <NUM>. The air filters <NUM> are in communication with the air tube or other such delivery duct or line that routes air through the hose <NUM> and into the backpack assembly <NUM>. The air filters <NUM> are configured to filter the air that is drawn into the backpack assembly <NUM> from the shroud <NUM>. For example, the air filters <NUM> may be configured to remove, deactivate, or otherwise neutralize ozone.

The batteries <NUM> and/or a power supply within the backpack assembly <NUM> provide operating power for the UV lamp <NUM> of the sanitizing head <NUM> (shown in <FIG>, for example). The top wall <NUM> may be removably coupled to the front wall <NUM> and the rear shell <NUM>. The top wall <NUM> may be removed to provide access to the batteries <NUM> (such as to remove and/or recharge the batteries), for example. Additional space may be provided within the backpack assembly <NUM> for storage of supplies, additional batteries, additional components, and/or the like. In at least one example, the front wall <NUM>, the rear shell <NUM>, the base <NUM>, and the top cap <NUM> may be formed of fiberglass epoxy.

<FIG> illustrates a perspective front view of the harness <NUM> coupled to the backpack assembly <NUM>, according to an example of the present disclosure. The harness <NUM> may include shoulder straps <NUM> and/or a waist or hip belt or strap <NUM>, which allow the individual to comfortably wear the backpack assembly <NUM>.

Referring to <FIG>, in operation, the individual may walk through an area wearing the backpack assembly <NUM>. When a structure to be sanitized is found, the individual may position grasp the handle <NUM> and position the sanitizing head <NUM> as desired, such as by extending and/or rotating the sanitizing head <NUM> relative to the handle <NUM>. The individual may then engage an activation button on the handle <NUM>, for example, to activate the UV lamp <NUM> to emit sanitizing UV light onto the structure. As the UV lamp <NUM> is activated, air <NUM> is drawn into the shroud <NUM> to cool the UV lamp <NUM>, and divert any generated ozone into the backpack assembly <NUM>, where it is filtered by the air filters <NUM>.

The extendable wand assembly <NUM> allows the sanitizing head <NUM> to reach distant areas, such as over an entire set of three passenger seats, from a row within an internal cabin of a commercial aircraft.

<FIG> illustrates an ultraviolet light spectrum. Referring to <FIG>, in at least one example, the sanitizing head <NUM> is configured to emit sanitizing UV light (through operation of the UV lamp <NUM>) within a far UV spectrum, such as between <NUM> to <NUM>. In at least one example, the sanitizing head <NUM> emits sanitizing UV light having a wavelength of <NUM>. In at least one other example, the sanitizing head <NUM> is configured to emit sanitizing UV light within the UVC spectrum, such as between <NUM> to <NUM>. In at least one example, the sanitizing head <NUM> emits sanitizing UV light having a wavelength of <NUM>. Optionally, the sanitizing head <NUM> can be configured to emit UV light at wavelengths other than within the far UC spectrum or the UVC spectrum.

<FIG> illustrates a perspective view of a portable sanitizing system <NUM>, according to an example of the present disclosure. The portable sanitizing system <NUM> includes a case assembly <NUM> that is configured to store the wand assembly <NUM> (hidden from view in <FIG>) when the case assembly <NUM> is in a closed position, as shown in <FIG>.

The adapter modules <NUM> shown and described with respect to <FIG> can be used with the sanitizing head of the wand assembly <NUM>.

The case assembly <NUM> may be formed of plastic, for example. The case assembly <NUM> includes a main body <NUM>, such as a shell, lower body portion, or the like. A cover <NUM>, such as a lid, or upper body portion, is moveably coupled to the main body <NUM>. For example, the cover <NUM> may be coupled to the main body <NUM> through a hinge that allows the cover <NUM> to be opened and closed relative to the main body <NUM>.

The main body <NUM> includes a base <NUM> connected to a rear wall <NUM>, lateral walls <NUM>, and a top wall <NUM>. The cover <NUM> is moveably coupled to a first lateral wall <NUM>, such as through a hinge. One or more latches <NUM> are disposed on a second lateral wall <NUM>, opposite from the first lateral wall <NUM>. The latches <NUM> are configured to engage one or more reciprocal latch members <NUM> extending from the cover <NUM> to secure the cover <NUM> in the closed position. The latches <NUM> may be engaged by an individual to disengage the latch members <NUM> to allow the cover <NUM> to be pivoted into an open position.

A handle <NUM> is secured to the case assembly <NUM>. For example, the handle <NUM> is pivotally secured to a lateral wall <NUM>. The handle <NUM> is configured to be grasped by an individual so that the portable sanitizing system <NUM> may be carried. Optionally, the handle <NUM> may be secured to other portions of the case assembly <NUM>, such as the top wall <NUM>. In at least one example, the handle <NUM> may be configured to retract into the case assembly <NUM> into a fully retracted position, and extend out of (for example, telescope out of) the case assembly <NUM> into a fully extended position.

Casters <NUM> or other such wheels may be rotatably secured to a portion of the case assembly <NUM>. For example, two casters <NUM> may be rotatably secured to the base <NUM> proximate to the rear wall <NUM>. An individual may tilt the case assembly <NUM> so that the casters <NUM> contact a floor. In this manner, the individual may roll the portable sanitizing system <NUM> via the casters <NUM> (and optionally through a handle in an extended position from the top wall <NUM>). Alternatively, the case assembly <NUM> may not include the casters <NUM>.

The hose <NUM> may outwardly extend from the case assembly <NUM>. In the closed position, when the wand assembly <NUM> is in a stowed position within the case assembly <NUM>, the hose <NUM> may be coiled over the cover <NUM>. A hose retainer <NUM> may secure the hose <NUM> in place on the cover <NUM>. For example, the hose retainer <NUM> may include a flexible fabric sheet <NUM> that is secured to a first side <NUM> of the cover <NUM>, and may removably secured to an opposite second side <NUM> of the cover <NUM>, such as through one or more fastening members <NUM>, such as hooks and loops, latches, clips, and/or the like. The hose retainer <NUM> is configured to secure the hose <NUM> on the cover <NUM> when the wand assembly <NUM> is within a storage chamber of the case assembly <NUM> and the cover <NUM> is in a closed position. Alternatively, the hose <NUM> may be contained within a storage chamber of the case assembly <NUM> when the wand assembly <NUM> is not in use. That is, the storage chamber may be sized and shaped to also contain the hose <NUM> when the wand assembly <NUM> is also within the storage chamber and the cover <NUM> is in the closed position.

The wand assembly <NUM> within the case assembly <NUM> in the closed position is protected from inadvertent engagement, bumping, and the like. That is, by storing the wand assembly <NUM> within the case assembly <NUM>, which is closed, when the wand assembly <NUM> is not in use, the portable sanitizing system <NUM> protects the wand assembly <NUM> from potential damage, and increases the useful life of the wand assembly <NUM>.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> having the case assembly <NUM> in an open position, according to an example of the present disclosure. As shown, the cover <NUM> is opened via a hinge <NUM> that pivotally couples the cover <NUM> to the main body <NUM>.

An internal or storage chamber <NUM> is defined between the base <NUM>, the lateral walls <NUM>, the rear wall <NUM>, and the top wall <NUM> (and the cover <NUM>, when closed). Various components of the portable sanitizing system <NUM> may be stored within the storage chamber <NUM>. For example, the components within the backpack assembly <NUM>, as described with respect to <FIG>, may be contained within the storage chamber <NUM>.

For example, when not in use, the wand assembly <NUM> is contained within the storage chamber <NUM>. Additionally, one or more batteries, such as rechargeable Lithium batteries, may be contained within the storage chamber <NUM>.

An air generation sub-system (such as a cooling fan) may also be contained within the storage chamber <NUM>. The air generation sub-system may be in fluid communication with an air tube within the hose <NUM>. The hose <NUM> may be removably connected to the air generation sub-system. In at least one example, the hose <NUM> is configured to be coupled to and uncoupled from the wand assembly <NUM> and the air generation sub-system. That is, the hose <NUM> may be removably coupled to the wand assembly <NUM> and the air generation sub-system.

One or more air filters, such as carbon filters, may also be within the storage chamber <NUM>. The air filters may be in communication with the air tube or other such delivery duct or line that routes air through the hose <NUM>.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> having the case assembly <NUM> in the open position, according to an example of the present disclosure. The wand assembly <NUM> is configured to be stowed in the storage chamber <NUM>. When the wand assembly <NUM> is to be used, the cover <NUM> is opened, and a first end <NUM> of the hose <NUM> is coupled to the port <NUM> of the wand assembly <NUM>. In at least one example, the hose <NUM> is configured to channel cooling air into the wand assembly <NUM>, in order to cool the UV lamp <NUM> during activation.

A second end <NUM> of the hose <NUM> may be connected to a port <NUM> extending into and through a portion of the main body <NUM>, such as through a portion of the top wall <NUM>. The port <NUM> connects the hose <NUM> to an air generation sub-system, such as a cooling fan <NUM> that is within the storage chamber <NUM>. The cooling fan <NUM> may be activated to generate cooling air that is delivered to the wand assembly <NUM> through the hose <NUM> (such as an air tube within the hose <NUM>, or through an internal passage of the hose <NUM> itself).

One or more batteries <NUM> may also be stowed within the storage chamber <NUM>. For example, three batteries <NUM> may be within the storage chamber <NUM>.

A power supply <NUM> is also contained within the storage chamber <NUM>. The power supply <NUM> may be coupled to the wand assembly <NUM> through a power cord (such as via a plug and receptacle fitting) to provide power to the wand assembly <NUM>. Further, the power supply <NUM> may be configured to provide power to the batteries <NUM> (such as to recharge the batteries <NUM>). The batteries <NUM> may be secured to the wand assembly <NUM> and provide power to the wand assembly <NUM>, so that the wand assembly <NUM> may be used without connection to the power supply <NUM>.

The cooling fan <NUM> couples to the hose <NUM> via the port <NUM>. The cooling fan <NUM> may also include a diverter port that couples to an internal portion of the power supply <NUM>. In this manner, cooling air may be delivered to both the hose <NUM> (and therefore the wand assembly <NUM>), and the power supply <NUM>, thereby providing cooling to both the wand assembly <NUM> and the power supply <NUM>.

A hole <NUM> may be formed through a portion of the case assembly <NUM>. For example, a hole <NUM> may be formed through a portion of the top wall <NUM> and sized and shaped to allow the hose <NUM> to pass therethrough. In this manner, the hose <NUM> may remain connected to the wand assembly <NUM> even when the wand assembly <NUM> is contained within the storage chamber <NUM> and the cover <NUM> is closed. Other portions of the hose <NUM> between the first end <NUM> and the second end <NUM> may be secured to the cover <NUM> by the hose retainer <NUM>, as shown and described with respect to <FIG>.

As shown, the handle <NUM> may be secured to the top wall <NUM> of the main body <NUM>. The handle <NUM> may be configured to retracted into and extend out of the main body <NUM>. For example, the handle <NUM> may be a telescoping handle.

The wand assembly <NUM> is removably secured within the storage chamber <NUM>. For example, the wand assembly <NUM> may be removably secured within the storage chamber <NUM> by one or more latches, clips, or via an interference fir with a conforming portion of the case assembly <NUM>.

The power supply <NUM> may be fixed in position within the storage chamber <NUM>. For example, the power supply <NUM> may be fixed in the storage chamber <NUM> by one or more fasteners, adhesives, or the like. Optionally, the power supply <NUM> may be secured in position by one or more latches, clips, or the like.

The batteries <NUM> may similarly be fixed position within the storage chamber <NUM>. For example, the batteries <NUM> may be fixed in the storage chamber <NUM> by one or more fasteners, adhesives, or the like. Optionally, the batteries <NUM> may be secured in position by one or more latches, clips, or the like. In at least one other example, the batteries <NUM> may be removable, and configured to couple directly to the wand assembly <NUM> to provide power thereto.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> having the case assembly <NUM> in the open position, according to an example of the present disclosure. A power cord <NUM> may also be stowed within the storage chamber <NUM>. The power cord <NUM> is contained within the case assembly <NUM> when the cover <NUM> is closed and the portable sanitizing system <NUM> is moved when the wand assembly <NUM> is not being operated.

Optionally, the power cord <NUM> connects the power supply <NUM> to a source of power (such as a wall outlet). In addition to supply air to the wand assembly <NUM>, the hose <NUM> also routes electrical cables and the like to the wand assembly <NUM> from the power supply <NUM> and the batteries <NUM>.

Optionally, the hose <NUM> may not include electrical connections to the wand assembly <NUM>. Instead, the wand assembly <NUM>, the power cord <NUM> may plug into the wand assembly <NUM>, via the plug <NUM>, to supply power from the power supply <NUM> and/or the batteries <NUM>. In this example, as the wand assembly <NUM> is operated, the plug <NUM> of the power cord <NUM> is connected to a reciprocal receptacle of the wand assembly <NUM>. An opposite end of the power cord <NUM> is connected to the power supply <NUM> (and/or, a battery <NUM>). The power cord <NUM> extends out of the case assembly <NUM> through the hole <NUM>. Thus, the wand assembly <NUM> may be removed from the storage chamber <NUM> and connected to the hose <NUM> and the power cord <NUM>, which extend through the hole <NUM>. The cover <NUM> may then be closed, thereby securely retaining the power supply <NUM>, the batteries <NUM>, and the like within the storage chamber <NUM>. The wand assembly <NUM> may then be activated, as it is powered via the power supply <NUM> or one or more of the batteries <NUM>, and the closed case assembly <NUM> may be moved, such as via an individual grasping the handle <NUM> and rolling the case assembly <NUM> via the casters <NUM> (shown in <FIG> and <FIG>).

Further, the hole <NUM> also allows intake air to be drawn into the storage chamber <NUM>, even when the cover <NUM> is closed over the main body <NUM>. Accordingly, the cooling fan <NUM> is able to receive fresh air, even when the cover <NUM> is closed.

The power supply <NUM> may be configured to receive power from a standard power supply, such as a source of alternating current power. For example, the power supply <NUM> may connect to the source of alternating current power through a power cord. The power cord <NUM> connects to the wand assembly <NUM>, and is configured to deliver power to the wand assembly <NUM> to operate the UV lamp <NUM> from power received from the power supply <NUM> and optionally the batteries <NUM>. For example, when the power supply <NUM> is connected to a source of alternating current power, the wand assembly <NUM> is powered by the power supply <NUM>. In the absence of such power, the wand assembly <NUM> may be powered by the batteries <NUM>. For example, the wand assembly <NUM> receives power from the batteries <NUM> the power supply <NUM> is not plugged into a power outlet. If the power supply <NUM> is plugged into a power outlet, one or more relays in the power supply <NUM> switch over from the batteries <NUM> to alternating current power supply from the power outlet.

<FIG> illustrates a perspective lateral view of the wand assembly <NUM>, according to an example of the present disclosure. As shown, the handle <NUM> may be fixed in relation to the shroud <NUM>. For example, the handle <NUM> may be integrally molded and formed with the shroud <NUM>. The wand assembly <NUM> may be small and compact in order to fit in confined spaced, such as within a flight deck of an aircraft.

An activation trigger <NUM> is moveably coupled to the handle <NUM>. For example, the activation trigger <NUM> may be secured to an underside <NUM> of a main beam <NUM> of the handle <NUM>. The activation trigger <NUM> is configured to be selectively pressed and/or depressed to activate and deactivate the UV lamp <NUM> of the wand assembly <NUM>, as desired.

The activation trigger <NUM> may be located anywhere along the length of the handle <NUM>. The activation trigger <NUM> may be shaped differently than shown. Further, the activation trigger <NUM> may be smaller or larger than shown. As an example, the activation trigger <NUM> may be a circular button, instead of an elongated bar or beam, as shown. Also, optionally, the activation trigger <NUM> may be located on a top portion of the main beam <NUM>, or on an extension beam <NUM>, which spaces the handle <NUM> from the shroud <NUM>. As another example, the activation trigger <NUM> may be located on a portion of the shroud <NUM>.

<FIG> illustrates a perspective bottom view of the wand assembly <NUM> of <FIG>. As shown, the reflector <NUM> is secured to an underside of the shroud <NUM>.

<FIG> illustrates a perspective front view of an aircraft <NUM>, according to an example of the present disclosure. The aircraft <NUM> includes a propulsion system <NUM> that includes engines <NUM>, for example. Optionally, the propulsion system <NUM> may include more engines <NUM> than shown. The engines <NUM> are carried by wings <NUM> of the aircraft <NUM>. In other examples, the engines <NUM> may be carried by a fuselage <NUM> and/or an empennage <NUM>. The empennage <NUM> may also support horizontal stabilizers <NUM> and a vertical stabilizer <NUM>.

The fuselage <NUM> of the aircraft <NUM> defines an internal cabin <NUM>, which includes a flight deck or cockpit, one or more work sections (for example, galleys, personnel carry-on baggage areas, and the like), one or more passenger sections (for example, first class, business class, and coach sections), one or more lavatories, and/or the like. The sanitizing systems described herein can be used to sanitize surfaces, components, and the like within the internal cabin <NUM>.
