Pavilion Sleeping Station (PSS) for shielding from ARS

The research described on this page was carried out at the primary research site in Hampton, VA 23666 which was closed August 25 - 28 of 2025 due to the lack of funds and the Pavilion Sleeping Station (PSS) decommissioned.

This page describes the initial stages of the design of the Pavilion Sleeping Station (PSS).  Further activities are described on separate pages related to the work on DPTOAVS and shielding of the PSS.

The Pavilion Sleeping Station (PSS) is a sleeping station based on a queen bed currently investigated as an alternative to the previously evaluated DSS sleeping station.  The research into the DSS sleeping station has been put on hold effective August 26, 2024 but may be revisited in the future.

Previous experiments with the DSS indicate that a multi-layer structure above the sleeping area is desired for better shielding from ARS.  This finding was confirmed during the initial PSS single layer all metal "roof" design stage (as shown in Fig. 1) which is not recommended.

The general structure and the ongoing progress in the design of the PSS is illustrated in Fig. 2 through 6 below.  The PSS is being designed to contain multiple layers of metal and non-metal roof shielding.  As can be seen the PSS consists of an elevated mattress on a metal frame (Fig. 2 and Fig. 3), layers of bottom (Fig. 5) and top (Fig. 6) metal shielding above the mattress and below the bed box frame, and a removable elevated sleeping area containing a twin mattress (Fig. 4).  Further shielding and structural improvements are currently being experimented with.

Two sleeping configurations are currently being evaluated: (1) with the sleeping area elevated from the ground as shown in Fig. 6 and 4, and (2) with the sleeping area located on the floor under the PSS.  The initial results suggest that the PSS is capable of some reduction in the ARS exposure.  The larger surface area of the PSS compared to DSS appears to result in better shielding from ARS even when the sleeping area is located on the floor under the PSS (as opposed to the elevated sleeping area of the PSS).  Further tests and refinements of the PSS are underway to establish the optimum configurations.  The current findings consistent with the previous DSS test results indicate that better shielding requires a (1) multi-layer metal and non-metal structure, (2) the reduction and/or elimination of gaps in the protective metal dome structures, and (3) larger surface area of the shielding surfaces compared to the room occupied.  Observations also suggest that the influx of fresh outside air reduces the severity of ARS exposure.

Elevated sleeping area tests

The ARS effects experienced by the AP conducted with the sleeping area elevated (as shown in Fig. 4 and Fig. 6) were comparable to the previous observations in the DSS until after a fresh air test was conducted.  The fresh air test was carried out by opening the two windows at the back of the sleeping station visible in Fig. 1 through 5, and opening the third window (visible at the right in Fig. 1 through 4) about 4 inches (10 cm) wide.  This test was conducted when the nightly temperatures where in the vicinity of 32℉ (0℃) with the apartment heater running and the door to the bedroom with the sleeping station closed which resulted in a significant influx of fresh air with a high degree of circulation and intermixing inside of the apartment by the built in apartment "forced head" unit.

Once in the sleeping station during the fresh air test the following effects were experienced.  The ARS vibrational cloud felt being induced in the feet had an unusually low frequency (only several Hz) and the highest amplitude (as much as ~10 cm) ever observed (a similar effect though not as pronounced was previously observed in the DSS after the metal shielding was improved).  Shortly after that a formation of some matter was felt by the AP within the regions where the spacial vibrations were experienced.  Writer is inclined to think that the vibrational cloud regions are volumes of space where some form of matter (referred to as ARS matter) is formed (or teleported to) through an unknown physical process (i.e. by means of electromagnetic or other radiation, or other ways) which is partially shielded by the sleeping station dome.  By analogy, it is well known that electromagnetic waves of longer wavelength are better at traveling around obstacles compared to shorter waves which require a line of sight access.  Since the fresh air test could make it difficult to form the ARS matter in the vicinity (i.e. for the propagation thorough the mattress surface etc.) due to constant air circulation and replenishment from outside, it could be necessary to "create" the ARS matter directly under the protective dome.  As such, bypassing shielding improvements of the sleeping station would be expected to require the use of longer wavelengths capable of propagating through the gaps in the protective dome.  One possible explanation of why the creation / teleportation of ARS matter remotely at desired locations could be possible is if, for example, the conclusions of the Michelson-Morley experiment (about the existence of light aether) where incorrect which is believed by some scientists and has been suggested in the past (i.e. this link).

In general, the current shielding efficiency of the elevated sleeping area of the PSS proved inadequate for proper sleeping.  Observations suggest that elevating the sleeping area results in harsher ARS exposure though the sleeping surface.  Although the elevated sleeping area tests carried out so far did not include an outside air ventilation system.

The fresh air tests conducted in the PSS suggested the need to equip the PSS with an outside air ventilation system which is described further on this page.

Floor sleeping area tests

Initial floor sleeping area tests where conducted when the PSS setup looked similar to the one depicted in Fig. 6 (sleeping area not shown) with very limited side shielding.  Nonetheless the shielding demonstrated was superior to that with the elevated sleeping area (see Fig. 4 and 6).  Shortly after moving the sleeping area to the floor the severity of ARS exposure went down, and observations where made which suggested that the effective use of the remote sensing pulse was temporarily hindered.  Namely, the remote sensing pulse which would typically be felt hitting the back side of the head would terminate at the upper back instead, or appear to be arriving from the ground towards the side of the head.  Eventually the intensity of the ARS exposure experienced while sleeping on the floor went up to an uncomfortable level and additional side shielding had to be attempted (as can be seen in Fig. 7) though the full metal panel coverage does not appear optimal at the moment.  It was also noticed that on the days when the windows were closed or partially opened and the forced heat unit was on the intensity of ARS effects intensified with an increased perception of matter present and moving around the body with a perceived capability to penetrate and build up in the tissue.

The tests conducted so far suggest that a sleeping area located on the floor may be more effective than an elevated sleeping area if a large surface area protective dome is used, and the sleeping area is well ventilated with outside air.  Although it should be pointed out that an elevated sleeping area with a forced outside air ventilation has not been tested yet.

Additional shielding and ventilation of the PSS

As a next step a ventilation system based on a Bissell air400 air purifier was implemented for the PSS as shown in Fig. 7 and 8.  As can be seen the ventilation approach includes taking in air from outside (Fig. 8) and forcing it into the PSS.  The idea behind this approach is to create a constant light fresh outside air airflow through the PSS to reduce the amount of ARS matter in the vicinity of the body.   The Affected Person reports a substantial reduction in the severity of ARS exposure after the ventilation system has been implemented and believes that this approach also resulted in the reduction of the ARS severity in other parts of the research site apartment.  It should be pointed out that the entire metal panel covering shown in Fig. 7 may not be optimal from the ventilation stand point and initially caused a perception of electric charge being present inside of the PSS once implemented, which later went away but other ARS types set in.

Even though the shielding used in PSS and the ventilation approach do not block the ARS from entering the PSS, the ventilation approach appears to be one of the most effective ARS severity reduction techniques implemented to date.   In contrast to the approach used in Fig. 7, preliminary tests suggest a gap between the metal panels and the floor at the bottom of the PSS may improve airflow and make ARS effects less severe.  This assumption needs to be verified.  Further shielding experiments/improvements are planned once/if the ARS phenomenon is better understood.

Due to a larger available inside space of the PSS compared to DSS, the PSS is also suitable for an installation of a small protected work desk area.

Sides and floor shielding experiments

Fig. 9 shows the head side of the sleeping platform within the PSS.  It was observed that introducing the additional aluminum-foiled cardboard (shown in Fig. 10) above the head area would lead to the reduction of what was felt as a remote sensing pulse on one occasion.  An aluminum-foiled cardboard structure placed over the sleeping platform would also lead to the reduction of sweating along the right side of the body of the AP.   These initial shielding experiments demonstrate a need for improvements and better elimination of gaps and/or preferably a multi-layer structure for the side walls of the PSS.

Even with the side shielding as shown in Fig. 8 above, the setup of the sleeping surface on the floor eventually led to the perception of harsher ARS effects (i.e. vibrating cloud, see types) by the AP.  One of the common effects experienced is the propagation of the ARS matter from the ground or from under the sleeping surface.  In an attempt to shield from these effects the sleeping area was raised slightly and a large number water-filled steel canisters was placed under the sleeping surface as shown in Fig. 11.  Immediately after this addition was implemented a low frequency large amplitude vibrating cloud effect was experienced by the AP along the entire body while laying down in the sleeping station followed by a scanning vibrating cloud moving along the body also of low frequency and large amplitude.  It is speculated that the small gap between the sleeping surface and the water-filled canisters caused the ARS matter to "be attracted" to water thus reducing the amount of the ARS matter capable to interacting with the body of the AP while laying on the sleeping surface.  This test was conducted because it was noticed that a placement of a bucket filled with a large number of 3 Oz stainless steel flasks filled with water under a chair the AP was seating on inside the sleeping station would reduce the perceived ARS matter propagation towards the body of the AP from under the sit.  Experiments with aluminum soda cans instead of the stainless steel canisters are planned.  Such shielding approach appears to be useful only if the ARS matter is felt propagating up from under the sleeping surface.  It is not currently clear if the placement of canisters under the sleeping surface may potentially make it easier to target the AP using other ARS approaches.  Further tests are needed for final conclusions.

Since the current shielding efficiency of the PSS is limited, a space/thermal bag shown in Fig. 12 (used inside out with the reflective surface on the outside while being covered with regular blankets above) was added to the sleeping setup within the PSS which appears to provide additional shielding and some reduction in the intensity of the remote sensing pulse when the sleeping bag is covering the back of the head and neck.  It should be pointed out that the space/thermal sleeping bag configuration has not been tested long enough to establish its anti-ARS effectiveness.  It was observed, for example, that the ARS matter can still be deposited inside of the sleeping bag though the bag opening.  Covering the head with the sleeping bag also isolates the head from the sleeping pillow water flask making other ARS types usable such as the "Digital (energy) droplets".  While the use of the sleeping bag appears to reduce some ARS effects, it has some drawbacks including causing perspiration.

Due to their low cost, further shielding experiments using space/thermal blankets are planned.  These plans were inspired by Slide 1 from the following news story about Evan Neumann.

Outside air ventilation preliminary results

The initial outside air ventilation proved to be very effective.  The primary advantage of the outside air ventilation is believed to be the significant reduction of the amount of ARS matter felt to be inhaled by the Affected Person and the reduction of the severity of other ARS effects possibly due to the higher amount of oxygen present in the air.  More recently the severity of ARS effects increased inside of the PSS which is believed to be due to the ARS matter being instigated into the PSS through the outside air ventilation system.  This assumption is based on an observation made when the Bissell air400 system located inside of the PSS (as shown in Fig. 13) accidentally got switched off by a time delay switch and it was uncovered that the ARS induced effects did not get worse while sleeping in an unventilated PSS.  Manually changing the fan speed in the Bissell air400 and/or switching it off appeared to confirm this assumption showing an increase in intensity of multiple ARS effects after the fan was switched on and vice versa.  Writer previously assumed that this increase was due to a capability of remotely creating the ARS matter somewhere within the ventilation system i.e. at the intake of the outside air ventilation air duct which is currently not protected by any metal shielding.  It was later found that a rupture of the intake hose at the input to the Bissell Air400 based air pump was the reason for the increase (see Fig. 15 below).

Preliminary tests suggest that the addition of a filtering media (as can be seen from Fig. 14) to the Bissell air400 air purifier unit reduced the intensity of the ARS effects until after the rupture of the outside air intake pipe was discovered.  This result suggests that the ARS matter includes some sorts of spatial structures with sizes big enough that even a coarse filtering media is able to obstruct or damage / destruct.  As such it is speculated that the addition of filtering media (examples include a discontinued Filtrete 9808 and AC Safe AC-302/50R) to the HVAC output vents inside of the Hampton, VA 23666 research site apartment should lead to the reduction in the severity of the ARS induced effects.  It should also be pointed out that it was observed that switching off the HVAC unit at the Hampton, VA 23666 research site apartment was reported by the AP to reduce the severity of ARS effects.

One ventilation approach currently in place at the Hampton, VA 23666 research site is by opening one window and switching on at least one bathroom ventilation fan to create a slow rate air displacement without causing discomfort.  A similar approach is inadvertently implemented at the Northampton Brunch Hampton Public Library (described further on this page) because the restrooms are located at both sides of the entry reception desk there.  A similar effect for a large building could be implemented by using a "whole house fan".

The addition of the filter to the Bissell air400 air purifier inside the PSS did however reduce the air flow making it possible for more ARS matter to be accumulated/created around the AP's body in the sleeping station using other ARS types.  Improvements to the outside air ventilation systems are required to ensure sufficient comfortable ventilation of the sleeping area around the AP's body.

Planned experiments include the use of multiple air ducts to pump in and evacuate air from the sleeping station as inspired by Slide 1 from the following news story about Evan Neumann.

Outside air ventilation system repair

A rupture of the PSS outside air ventilation system intake duct as shown in Fig. 15 was found which explains why the ARS exposure inside of the PSS got worse.  Upon repair the intensity of the ARS effects subsided considerably.  This finding once again confirms that the outside air ventilation is one of the most effective ARS severity reduction techniques.

Outside shielding of the PSS using space/thermal blankets

As indicated previously it was found that the previously used side shielding of the PSS shown in Fig. 7 was inadequate.  A new shielding scheme involving the use of space/thermal blankets (as shown in Fig. 16 and 17) is being experimented with.  The initial shielding approach retains only a few metal shielding components including the roof and the bottom metal frame shielding shown in Fig. 5.  The current shielding approach utilizes the "cabbage" structure with multiple layers of blankets on top of one another with an overlap to form at a minimum a 3-layer structure throughout the entire shielding dome. The space/thermal blankets shielding allows shielding from all WiFi networks in contrast to the previously used all-metal shielding approach with gaps shown in Fig. 7.  The initial observations indicate that the use of space/thermal blankets reduced ARS related discomfort and made sleeping more comfortable compared to the all-metal shielding scheme previously used but resulted in feeling less energetic upon waking up.  The use of the previously implemented all-metal shielding on the other hand (which contained a lot of gaps) allowed more ARS effects through but allowed the Affected Person to wake up feeling more energetic despite experiencing harsher ARS related discomfort upon waking up.  The space/thermal blankets insulation also allowed some harsher ARS impact through felt as a type of "electrified vibrations" during the second night after being implemented.  These observations are thought to be attributed to a much better overall coverage of the space/thermal blanket shield design but the lack of bulkier metallic structures in the shielding dome which previously demonstrated anti-ARS shielding efficiency.

The original space/thermal blanket shielding approach shown in Fig. 16 did not include a layer of space/thermal blanket between the box frame and the mattress.  As such shortly after the approach shown in Fig. 16 was implemented the Affected Person could feel a vibrating cloud deposition pulse propagating from above within the sleeping station which was believed to be attributed to the lack of space/thermal blankets between the box frame and the mattress.  Since the box frame is mostly hollow inside and the the ARS matter previously demonstrated capability to easily propagate within porous media such as foam (i. e. the description related to the remote sensing pulse including the laundry room test).  To remedy this vulnerability an extra (4 or more ply) space thermal blanket layer was added between the box frame and the mattress as can be seen in Fig. 17.

It should be pointed out that the gaps in the all-metal sleeping station allow ARS deposition into the sleeping station even when there is little to no line-of-sight access.  One time a vibrating cloud the size of the sleeping area was deposited into the sleeping station as it appears by penetrating through multiple gaps between sleeping station metal panels to recombine into a single large plume of a vibrating cloud inside of the PSS.  The deposition was also preceded/accompanied by what appeared to be an audible sound with higher intensity than typically felt which is attributed to a larger volume of vibrating cloud being deposited.  On that specific occasion is was possible to neutralize the vibrating cloud plume deposited with a "Saulute" xenon gas-discharge tube photo flash.

Past observations in the DSS sleeping station indicated a perception of a whole DSS sleeping station structure vibration/buzzing (resembling a feeling of being on a passenger plane when it just starts to descend) after several effective shielding approaches (i.e. the improvement of the shielding dome, the addition of the wings) were implemented.  Writer is inclined to think that such vibrations/buzzing experienced were attributed to some field (i.e. electromagnetic) acting upon the metallic structure of the dome.  As such the presence of bulkier metallic elements in the body of the sleeping station (even in the presence of gaps) is thought to be an essential component of anti-ARS shielding.

Given the above, a metal shielding dome with better coverage (fewer and smaller gaps) supplemented with an outside space/thermal blankets shielding is the shielding approach to be evaluated next.

Dual Layer (metal / space blanket) shielding and gaps shielding

In order to improve the shielding efficiency of the PSS a dual layer (inner metal dome + outside space/thermal blanket shield) is being implemented including the reduction of gaps in the metal shielding dome.  In order to perform the these improvements the space/thermal blanket cover was lifted up as shown in Fig. 18.

During the shielding process the sleeping area was slightly lifted from the ground and a metal panel under-layer introduced directly under the sleeping surface as a test as shown in Fig. 19 and 20.  The use of the optical table in Fig. 20 was only dictated by the lack of the plywood panels of correct size at the time the photo was taken.  The placement of water-filled steel canisters under the sleeping surface was previously suggested as an ARS severity reduction method but instead of decreasing the strength of ARS exposure was found to make the perceived ARS effects stronger in later experiments.  What this change is attributed to is currently not understood.

Observations made to date suggest that the presence of even small gaps allows the ARS matter/pulses to propagate inside of the PSS.  As such PSS metal dome gaps shielding is currently being implemented.  For example, Fig. 21 shows a gap between the metal frame and one of the metal shielding panels which corresponds to the outside view of the same section shown in Fig. 22.  Another example of gaps being eliminated is shown in Fig. 23 even though it is not currently clear if all of these gaps must be patched.

Fig. 24 shows an example of the gaps patching approach using space/thermal blankets and aluminum foil being implemented.  Experiments suggest that aluminum foil gaps patching is superior to the thermal blanket shielding and that tight aluminum foil gap patching significantly improves anti-ARS shielding efficiency.  As such, thermal blankets are only considered a supplementary shielding material to be used in addition to the aluminum foil.

Outside air ventilation system improvements

Fig. 25 shows the current installation of the outside air intake unit (Bissell air400) located inside of the PSS.   Modifications are underway to improve the ventilation of the PSS.  Recent shielding improvement have restricted the airflow from inside of the PSS suggesting a need for an output ventilation channel to ensure good ventilation inside of the PSS.  Warmer outside temperature also caused the air forced into the PSS to stay higher inside of the PSS instead of moving towards the floor causing an increase in the exposure of the Affected Person to ARS.

Distributed Pass Through Outside Air Ventilation System (DPTOAVS)

Inspired by the first slide in this news story about Evan Neumann, a Distributed Pass Through Outside Air Ventilation System (DPTOAVS) containing multiple outside air intake ducts and multiple output air ducts is being implemented in the PSS.  The initial design stages are depicted in Fig. 26 through 28.  As can be seen from Fig. 26 an additional Bissell air400 unit was added for the evacuation of air from the PSS.  The inside of the PSS is depicted in Fig. 27 showing the air intake Bissell air400 on the left and two output air ducts.  The output air ducts are connected to the second Bissell air400 unit shown in Fig. 28 located outside of the PSS.  Future implementations will allow the output air of the second Bissell air400 to be routed to another window to be evacuated into the outside environment which is expected to reduce the heating/cooling expenses associated with the introduction of the outside air into the apartment though DPTOAVS.  The routing of the output air into another window located away from the intake window would also avoid the introduction of (potentially ARS contaminated) air which passed through the PSS into the apartment.

The Bissell air400 units used allow up to 6 ducts to be connected to the suction port and up to 3 to the evacuation port (4-inch diameter air ducts are currently used).  As such as many as 6 outside air intake and 6 air evacuation ducts may be implemented in the PSS in the future which would improve air exchange in the PSS and reduce the stress on the Bissell air400.  The addition of a larger number of outside air intake air ducts would also allow better heating/cooling of the intake air as it travels towards the PSS due to the reduced air flow though each duct and larger surface area contact with the walls of the aluminum ducts located in a heated/cooled environment.

Experiments with the placement of DPTOAVS output air ducts shown in Fig. 27 has demonstrated the capability of the output air duct system to reduce the severity of the ARS exposure inside of the PSS by evacuating the air from selected locations inside of the PSS where (or in proximity to where) the ARS matter is being felt to be induced.  The exact optimum arrangement of the output air ducts has not been established as of yet but it was observed that the placement of an output air duct under the sleeping surface reduces the perception of the ARS matter turbulent circulation around the body of the Affected Person (in this configuration the closer duct shown in Fig. 27 is placed under the sleeping surface, and the one shown in the back of the photo is used at variable locations).  It was also observed that the output air ducts are capable of reducing the perceived ARS effects if placed at locations where the ARS effects are felt being induced (in a vacuum cleaner manner).

More recent observations indicate a formation of an ARS cloud above the sleeping surface with an apparent capability to be transferred to the sleeping surface for further interfacing with the body of the Affected Person. The presence of the cloud at a higher elevation above the sleeping surface was detected when the AP bent his legs in the knees while laying on his back which resulted in a perception of a vibrating cloud present in the air slightly higher up above the sleeping surface.  Placing a suction duct above the sleeping surface and above the legs of the AP resulted in the reduction of the perceived ARS effects.  This observation is consistent with the previous observations indicating an increase in the perceived ARS exposure and stuffier air inside the PSS once the outside temperatures increase which is apparently caused by the reduction in the air exchange inside of the PSS.  To further improve the air exchange inside of the PSS a set of output air ducts on the outside air instigation channel is planned for better routing of the outside air into the desired locations inside of the PSS.

Further updates related to the design of the DPTOAVS will likely be presented as a separate web page.

Manual Xenon Gas Discharge Light Illumination System

The intense light produced by photo flashes equipped with the IFK-120 xenon gas discharge tubes was previously found effective against ARS.  A Soviet Union made "Saulute" xenon gas discharge tube photoflash paired with a 110V / 220V voltage converter is currently used in the PSS by the affected person in the manual mode.  The addition of an automated gas discharge light illumination system is planned.

Further shielding of the PPS including the floor

Aluminum foil gaps patching has led to improved anti-ARS shielding efficiency and is being implemented across the sleeping station.  Additions to the shielding includes the lining of the PSS floor with metal panels and aluminum foil gaps patching.  Floor shielding appears to be essential.  The PSS shielding information will be further summarized on a separate shielding page.

A church pavilion structure

Fig. 29 shows a pavilion being built at one of the Orthodox churches which inspired the design of the Pavilion Sleeping Station (PSS) and the use of a slightly raised floor (which allows placement of water-filled canisters under) in particular.  It should also be pointed out that arks supporting the roof (not visible) are made out of metal.

Buildings found at Fort Monroe, Hampton VA

Now lets take a look at several buildings located at the Fort Monroe in Hampton VA, a former military installation decommissioned in the Fall of 2011 and now open to the public.  Fig. 30 shows one newer pavilion style building (on the left) and an older multistorey building at a distance on the right.  A closer view of the older multistorey building is presented in Fig. 31.  As can be seen the roof of the older building is covered with roofing shingles commonly used in the United States.  On the other hand, Fig. 32 shows a closer view of newer pavilion style buildings with the 2-sided slanted roof covered with long continuous roofing panels (presumably made out of metal).  A side view of one of the buildings shown in Fig. 32 is shown in Fig. 33.  By comparing the photos in Fig. 31 and 33 it can also be seen that the windows in the older building are much bigger especially the section which can be opened.

The older building shown in Fig, 31 called the Randolph Hall was recently announced to be to be converted into an apartment building and is now being cleaned out as can be seen in Fig. 34.

The information about the time the newer pavilion style buildings shown in Fig. 30 - 33 were built is unavailable but the March 2012 photos from Google Maps include these buildings.  As such these newer buildings are believed to have been built while the Fort Monroe was still a military installation.  By inspecting the images in the Google Maps link it can also be recognized that the street lights contained old incandescent light bulbs which were recently (Winter(February?) of 2025) replaced with LED lights.

Northampton Brunch Public Library in Hampton, VA 23666 at "Pavilion Square"

Finally, lets take a look at this Hampton, VA library branch.  It was observed that the ARS effects experienced by the Affected Person are weaker at the Northampton Brunch Hampton Public Library located within of what is called the "Pavilion Square" (as can be seen in the Street View shown in Fig. 35) at 936 Big Bethel Rd. Hampton, VA 23666.  Writer assumes that the reduced intensity of the ARS effects is attributed to the pavilion building structure which is also constructed using a 2- and 4- sided slanted roof design (and appears to be made out of metal).  This assumption may be tested in the PSS design in the future.

The above library branch recently had hand dryers equipped with ultraviolet light installed.  Previously Writer presented the idea of using the ultraviolet light inside of the aluminum air-intake ducts of the PSS for the purpose of possibly destructing the ARS structures believed to be present in the air (as well as viruses and bacteris) as it being instigated into the PSS.  However this approach is unlikely to be implemented since the use of UV light for this purpose is likely to generate ozone which is harmful or deadly to inhale (depending on the concentration).
