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. However, UVC light typically takes a significant amount of time (for example, three minutes) to kill various microbes. Further, various microbes may not be vulnerable to UVC light. That is, such microbes may be able to withstand exposure to UVC light.

Also, certain types of microbes may develop a resistance to UVC light. For example, while UVC light may initially kill certain types of microbes, with continued exposure to UVC light over time, the particular species of microbe may develop a resistance to UVC light and able to withstand UVC light exposure.

Additionally, direct exposure of certain types of UV light may pose risk to humans. For example, certain known UV systems emit UV light having a wavelength of <NUM>, which may pose a risk to humans. As such, certain known UV light disinfection systems and methods are operated in the absence of individuals. For example, a UV light disinfection system within a lavatory may be operated when no individual is within the lavatory, and deactivated when an individual is present within the lavatory.

Further, certain UV light sanitizing systems include excimer lamps. Electrical connections to excimer lamps may be less than reliable due to generated heat. For example, a <NUM> UV lamp may have a low temperature solder joint that attaches an electrical braid to the lamp, which may result in failure of the connection at the high operating temperatures of the UV lamp. The generated heat may break a grid line in the braid attachment. Further, tape that is disposed over the braid attachment may also inadvertently pull the grid line off when the tape is removed. Further, the resulting arcing may adversely affect neighboring grid lines, which may lead to the lamp being disconnected from the electrical coupling.

<CIT>, in accordance with its abstract, states a flat lamp transmitting radiation in the ultraviolet, comprising: first and second flat dielectric walls that are facing each other, kept substantially parallel, and sealed, to one another, thus defining an internal space filled with gas, the first dielectric wall at least being made of a material that transmits said UV radiation; electrodes composed of first and second electrodes, having different given potentials, for a perpendicular discharge between the walls, the first electrode at least being based on a layer arranged in order to allow overall UV transmission; and an emitting gas or a phosphor coating on one main inner face of the first and/or the second dielectric wall, the phosphor emitting said UV radiation by being excited by the gas.

<CIT>, in accordance with its abstract, states a dielectric barrier discharge lamp that comprises a tubular airtight vessel consisting of an ultraviolet ray transmittable material and having exhaust chip on the side surface, an excimer generating gas sealed therein, an internal electrode sealed in the airtight vessel, and an external electrode of mesh structure engagingly locked by the exhaust chip in contact with the circumference of the airtight vessel. When knit-braided structure is adapted as the mesh structure of the external electrode to form a cylindrical body having a large diameter to the airtight vessel, and both the ends of the cylindrical body are pulled after inserting the airtight vessel to the inner part thereof, the knit-braided structure is elongated, deformed, contracted, and closely fitted to the airtight vessel, and engagingly locked by the exhaust chip.

<CIT>, in accordance with its abstract, states an electrical connector assembly including a hollow bored adapter having a forward end and a rearward end, the forward end having an electrical component attachment flange, the rearward end forming a hollow bored nipple, the hollow bore of the nipple being continuous with the hollow bore of the adapter, the hollow bored nipple having an outwardly opening channel; at least a first electrical cable extending through the hollow bore of the hollow bored adapter, and through the hollow bore of the hollow bored nipple, the at least first electric cable extending rearwardly from the rearward end of the hollow bored adapter; a flexible tubular sheath having a forward end overlying the hollow bored nipple's outwardly opening channel, the flexible tubular sheath extending rearwardly from the rearward end of the hollow bored adapter; and a thermoplastic strap capable of alternately assuming a longitudinally stretched configuration, and a shortened plastic memory configuration, the thermoplastic strap being spirally wrapped about the flexible tubular sheath so that the thermoplastic strap overlies the hollow bored nipple's outwardly opening channel.

A need exists for a system and a method for maintaining a reliable connection between a lamp of a sanitizing system and an electrical coupling.

With that need in mind, the claimed subject matter provides a system for connecting an ultraviolet (UV) lamp of a sanitizing system with an electrical coupling.

Moreover, unless explicitly stated to the contrary, embodiments "comprising" or "having" an element or a plurality of elements having a particular condition can include additional elements not having that condition.

Certain embodiments of the present disclosure provide a sanitizing system and method that includes an ultraviolet (UV) lamp (such as an excimer lamp) that emits UV light in a far UV light spectrum, such as at a wavelength of <NUM>, which neutralizes (such as kills) microbes (for example, viruses and bacteria), while posing no risk to humans. The UV lamp may be used within an internal cabin to decontaminate and kill pathogens. Embodiments of the present disclosure provide safer and more effective sanitation as compared to certain known UV systems. The UV lamp may be used in a portable sanitizing system or a fixed sanitizing system. For example, operating the UV lamp to emit sanitizing UV light having a wavelength of <NUM> may be used with a portable system or a fixed system.

Certain non-claimed embodiments provide a method to maintain an electrical connection and contact in relation to an ultraviolet (UV) lamp, such as a <NUM> excimer lamp. In at least one non-claimed embodiment, the method includes applying a thin conductive layer (such as formed of copper of aluminum) at a compression point where the electrical connection contacts the UV lamp. The method also includes compressing the conductive layer and electrical connection to the compression point with a mechanical restraining device such as tape or a clamp. The tape and/or clamp is formed of materials that maintain structural and thermal capabilities at a temperature of at least <NUM> degrees C, for example.

In at least one non-claimed embodiment, the method includes first applying a conductive layer to provide a greater area of electrical contact and spread heat to prevent a thermal hotspot. Next, the method includes applying a mechanical restraining device to secure the electrical braid and conductive layer together. In at least one non-claimed embodiment, the conductive layer is a thin material capable of conforming to the curved surface on the lamp, and is of a similar length as the lamp grid. The tape could be made of materials such as polyimide (Kapton), PEEK, Teflon, or Fiberglass, and is wrapped around the compression point to secure the conductive layer and electrical braid. The clamp may be formed of a thermoplastic material, and may have a C or U shape, with a hook on an open side to attach the open ends together to provide additional clamping force. The clamp is placed on the compression point to mechanically secure the conductive layer and electrical braid.

In at least one non-claimed embodiment, embodiments of the present disclosure provide an application of copper foil to prevent detachment of a conductive adhesive on high temperature excimer lamp. Further, although not claimed, embodiments of the present disclosure may be used to repair such connections.

In at least one embodiment, a constraint is used to secure a connection interface of a UV lamp. The constraint can be used with or without a conductive layer, such as a copper strip or a copper tape that is configured to spread current and provide a heat sink. Examples of the constraint may include a clamp, a tape, a fiberglass wrap, a non-conductive fiber wrap, a pressure clip, or other the like. In at least one embodiment, the constraint includes two or more of the clamp, the tape, the fiberglass wrap, the non-conductive fiber wrap, the pressure clip, and/or the like. According to the claimed subject matter, the constraint is a fiberglass wrap.

Certain non-claimed embodiments provide a method for maintaining electrical contact in relation to a UV lamp (such as a <NUM> UV lamp). The method includes applying a thin electrically conductive layer form of materials such as copper or aluminum at a compression point where the electrical connection contacts the UV lamp, and compressing the conductive layer and the electrical connection to the compression point with a mechanical restraining device or constraint, such as tape, a clamp, a clip, or a continuous band. The mechanical restraining device or constraint is formed of one or more materials that are capable of maintaining structural and thermal capabilities at a temperature of at least <NUM> degrees C, for example.

In at least one embodiment covered by the claimed subject matter, the mechanical restraining device or constraint is a fiberglass tension wrap that is wrapped around the compression point to secure a conductive layer to an electrical braid.

A clamp may be formed of a thermoplastic material and may have a C or U shape with a hook, latch, or spring on an open side to attach the open ends together to provide additional clamping force. In at least one embodiment, the clamp may be of a continuous design, such as a band, with varying thickness around the perimeter for desired stiffness properties. A curved beam may be used to allow for a high preload and low spring rate to mitigate differences in thermal expansion between the UV lamp and the clip.

<FIG> illustrates a perspective view of a portable sanitizing system <NUM> worn by an individual <NUM>, according to the claimed embodiment. 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 embodiment, the sanitizing head <NUM> is moveably coupled to the handle <NUM> through a coupler <NUM>.

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.

<FIG> illustrates a perspective lateral top view of the wand assembly <NUM>, according to an embodiment 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, such as a <NUM> excimer lamp.

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>. 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 embodiment, 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>.

<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 embodiment, the handle <NUM> may include a telescoping body that allows the handle <NUM> to outwardly extend and inwardly recede.

<FIG> illustrates a perspective view of the portable sanitizing system <NUM> in a compact deployed position, according to an embodiment 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 embodiment 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 embodiment 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 embodiment, 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 embodiment 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>. Appendix A illustrates different positions of the wand assembly <NUM>.

<FIG> illustrates a perspective end view of a UV lamp <NUM> and a reflector <NUM> of the sanitizing head <NUM>, according to an embodiment of the present disclosure. 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 embodiment, 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, 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.

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 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 embodiment, 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 embodiment, 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>.

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 embodiment 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 embodiment of the present disclosure. In this embodiment, 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 embodiment, 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 embodiment, 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>.

Referring to <FIG>, a rim <NUM> (such as a <NUM> (<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 embodiment, 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 embodiment, the ranging LEDs <NUM> may be disposed on or within the rim <NUM> and/or the cover plate <NUM>.

<FIG> illustrates a perspective end view of the UV lamp <NUM> secured to a mounting bracket or clamp <NUM>, according to an embodiment 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> (<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 an ultraviolet light spectrum. Referring to <FIG>, in at least one embodiment, 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 embodiment, the sanitizing head <NUM> emits sanitizing UV light having a wavelength of <NUM>.

Embodiments of the present disclosure provide systems and methods for maintaining a reliable electrical connection in relation to a UV lamp, such as a <NUM> UV lamp. Optionally, the UV lamp can be operated at different wavelengths, such as <NUM> or <NUM>. In at least one other embodiment, the UV lamp can be operated within the UV-C spectrum.

Optionally, the UV light may be at various other wavelengths. For example, the UV light may be within the far UV spectrum, such as between <NUM>-<NUM>. As another example, the UV light may be within the UVC spectrum, such as between <NUM>-<NUM>. As an example, the UV light may be emitted at a wavelength of <NUM>.

In at least one embodiment, the UV lamp is the UV lamp <NUM> within a portable sanitizing system, such as shown and described with respect to <FIG>. Optionally, embodiments of the present disclosure may be used with fixed sanitizing systems. For example, embodiments of the present disclosure may be used with UV lamps that are fixed within a structure, such as UV lamps that are fixed to a ceiling, a wall, a floor, or the like.

<FIG> illustrates an end view of a braid attachment <NUM> of a UV lamp <NUM>, according to an embodiment of the present disclosure. The UV lamp <NUM> includes or otherwise couples to the braid attachment <NUM>. The UV lamp <NUM> may be part of a portable sanitizing system, such as that shown and described with respect to <FIG>, or a fixed sanitizing system.

In at least one embodiment, the braid attachment <NUM> is an electrical braid at an end <NUM> of the UV lamp <NUM>. For example, the braid attachment <NUM> is configured to electrically connect to an electrical source, such as through one or more of an electrical braid, wires, couplings, or the like. The braid attachment <NUM> may extend along a length of the UV lamp <NUM>. For example, the braid attachment <NUM> may provide a cage structure that extends along at least a portion of a length of the UV lamp <NUM>.

The braid attachment <NUM> includes a mesh or screen <NUM> including a plurality of longitudinal linear wires <NUM> that intersect with a plurality of lateral linear wires <NUM>. For example, the longitudinal linear wires <NUM> may orthogonally intersect the lateral linear wires <NUM>, thereby forming a plurality of grid members <NUM>. In this manner, the longitudinal linear wires <NUM> and the lateral linear wires <NUM> may provide grid lines. The longitudinal linear wires <NUM> and the lateral linear wires <NUM> may be formed from a metal, for example.

In at least one embodiment, tape <NUM> is wrapped around the end <NUM> of the UV lamp <NUM>. The tape <NUM> may extend around at least a portion of an end of the braid attachment <NUM>. The tape <NUM> could be made of materials such as polyimide (Kapton), PEEK, Teflon, or Fiberglass. According to the claimed embodiment, the tape <NUM> is or includes a fiberglass wrap that is wrapped around the portion of the braid attachment <NUM>. The tape <NUM> can be wrapped around a compression area to secure the conductive layer and braid attachment <NUM>.

A foil <NUM> is secured around the braid attachment <NUM> at a compression area <NUM>. At least a portion of the foil <NUM> may be inboard from the tape <NUM>. That is, the foil <NUM> may be between the tape <NUM> and a center of the braid attachment <NUM>. Optionally, the tape <NUM> may wrap around an entirety of the foil <NUM>, thereby compressing the foil <NUM> into the braid attachment <NUM>. The foil <NUM> provides a greater area of electrical contact (such as in relation to an electrical coupling, such an electrical braid) and spreads heat thereover to prevent a thermal hotspot.

The foil <NUM> wraps around at least a portion of the braid attachment <NUM>. In at least one embodiment, the tape <NUM> is wrapped around at least a portion of the foil <NUM> (which provides a conductive layer) to compress the foil <NUM> in relation to the braid attachment <NUM>. That is, the wrapped tape <NUM> compresses the foil <NUM> into the braid attachment <NUM>.

In at least one other embodiment, the foil <NUM> does not touch the tape <NUM>. For example, the tape <NUM> may not wrap around the foil <NUM>. In a non-claimed embodiment, the tape <NUM> may not be used. Instead, a clamp may be used to compress the foil <NUM> in relation to the braid attachment <NUM>. In at least one other embodiment, both the tape <NUM> and the clamp may be used to compress the foil <NUM> in relation to the braid attachment <NUM>.

In at least one embodiment, the foil <NUM> is formed of copper. As another example, the foil <NUM> is formed of aluminum. The foil <NUM> provides a thin conductive layer that wraps around at least a portion of the braid attachment <NUM>. As an example, the foil <NUM> may have a thickness of <NUM> millimeters or less.

<FIG> illustrates a lateral view of the UV lamp <NUM>, according to a non-claimed embodiment of the present disclosure. The UV lamp <NUM> includes (or otherwise couples to) the braid attachment <NUM> extending between ends <NUM> and <NUM>. Compression areas <NUM> are located at or proximate to the ends <NUM> and <NUM>. Referring to <FIG>, the foil <NUM> providing the conductive layer (that is, the foil <NUM> is the conductive layer) is first secured to at least a portion of the braid attachment <NUM>. After the foil <NUM> is secured to the braid attachment <NUM> at the compression area <NUM>, a clamp <NUM> is secured to the foil <NUM>, thereby exerting a clamping force into the foil <NUM> at the compression area <NUM>.

In at least one non-claimed embodiment, the clamp <NUM> is formed of plastic. For example the clamp may be formed of a thermoplastic material, and may have a C or U shape, with a hook on an open side to attach the open ends together to provide additional clamping force.

<FIG> illustrates a perspective end view of the braid attachment <NUM> of the UV lamp <NUM> having the clamp <NUM>, according to a non-claimed embodiment of the present disclosure.

The clamp <NUM> includes a first arm <NUM> spaced apart from a second arm <NUM> by an orthogonal extension beam <NUM>. A clamping channel <NUM> is defined between the first arm <NUM>, the second arm <NUM> and the extension beam <NUM>. An opening <NUM> that leads into the clamping channel <NUM> is defined between free ends <NUM> and <NUM> of the first arm <NUM> and the second arm <NUM>, respectively. As such, the clamp <NUM> has a C or U shape.

After the foil <NUM> (shown in <FIG>) is wrapped around the compression area <NUM> of the braid attachment <NUM>, the clamp <NUM> is moved over the compression area <NUM> in the direction of arrow <NUM>, such that the compression area <NUM> of the braid attachment <NUM> is sandwiched between first arm <NUM> and the second arm <NUM>. In at least one non-claimed embodiment, the first arm <NUM> and/or the second arm <NUM> includes a fastener coupling <NUM>, such as a protuberance, that includes a passage <NUM> for receiving a fastener, such as a screw or bolt. The fastener is secured within the passage <NUM> and connects to the opposite first or second arm <NUM> or <NUM> that overhang the compression area <NUM>. The fastener may then be tightened, thereby urging the first arm <NUM> and the second arm <NUM> toward one another, which increases the clamping force of the clamp <NUM>.

In at least one non-claimed embodiment, the foil <NUM> can be applied to a portion of the clamp <NUM>. For example, tape <NUM> secured to interior surfaces of the arm <NUM> or <NUM> may include the foil <NUM>. As an example, the tape <NUM> can be a <NUM> (<NUM> inch) by <NUM> (<NUM> inch) copper tape applied over the braid attachment <NUM> and/or to the interior portion of the clamp <NUM>.

The clamp <NUM> is placed on the compression area <NUM>. The clamp <NUM> mechanically secures the conductive layer (for example, the foil <NUM>) to at least a portion of the electrical braid (for example, the braid attachment <NUM>). <FIG> illustrates a perspective end view of the clamp <NUM> secured around the conductive layer (that is, the foil <NUM>) wrapped around the compressive area <NUM> of the braid attachment <NUM>, according to a non-claimed embodiment of the present disclosure. In this embodiment, a securing arm <NUM> may extend from one or the other of the first arm <NUM> or the second arm <NUM> opposite from the extension beam <NUM>. The securing arm <NUM> may selectively lock and unlock the first arm <NUM> to the second arm <NUM>, thereby ensuring that the clamp <NUM> exerts a uniform and consistent clamping force. A fastener may or may not be used to secure the securing arm <NUM> in position. In at least one embodiment, the securing arm <NUM> latches or snaps in position with or without the use of a separate fastener.

Referring to <FIG>, certain embodiments of the present disclosure provide a method to maintain an electrical connection and contact on the UV lamp <NUM>, such as a <NUM> excimer lamp. The method includes applying a thin conductive layer (such as the foil <NUM>) at the compression area <NUM> where an electrical coupling <NUM> (such as an electrical braid) contacts the UV lamp <NUM>. The method also includes compressing the conductive layer and the electrical connection <NUM> to the compression area <NUM> with a mechanical restraining device such as tape <NUM> or tape <NUM> and the clamp <NUM>. The tape <NUM> and/or the clamp <NUM> are formed of materials that maintain structural and thermal capabilities at a temperature of at least <NUM> degrees C, for example. In at least one embodiment, the tape <NUM> is used in relation to the foil <NUM> without the clamp <NUM>. In at least one other embodiment, both the tape <NUM> and the clamp <NUM> are used in relation to the foil <NUM>. In at least one other non-claimed embodiment, the clamp <NUM> is used in relation to the foil <NUM> without the tape <NUM>.

Certain embodiments of the present disclosure provide a system <NUM> for connecting the UV lamp <NUM> with the electrical coupling <NUM>. The system <NUM> includes the braid attachment <NUM> coupled to the UV lamp <NUM>.

For example the UV lamp <NUM> may include the braid attachment <NUM>. Optionally, the braid attachment <NUM> may be separately coupled to the UV lamp <NUM>. A conductive layer (such as the foil <NUM>) is secured to at least a portion (such as an end portion) of the braid attachment <NUM>. In at least one embodiment, the conductive layer includes the foil <NUM> wrapped around the at least a portion of the braid attachment <NUM>.

In at least on embodiment, the system <NUM> also includes a mechanical restraining device configured to secure the braid attachment <NUM> to the electrical coupling <NUM>. For example, the mechanical restraining device includes the tape <NUM> wrapped around one or both of the portion of the braid attachment <NUM> or at least a portion of the conductive layer. As another non-claimed embodiment, the mechanical restraining device includes the clamp <NUM> secured around one or both of the portion of the braid attachment <NUM> or at least a portion of the conductive layer. As another example, the mechanical restraining device includes the tape <NUM> wrapped around one or both of the portion of the braid attachment <NUM> or at least a portion of the conductive layer, and the clamp <NUM> secured around one or both of the portion of the braid attachment <NUM> or at least a portion of the conductive layer.

<FIG> illustrates a flow chart of a method of securing the electrical coupling <NUM> (such as one or an electrical braid, one more electrical wires, fixtures, and/or the like that connect to a source of power) to a portion of the UV lamp, according to an embodiment of the present disclosure. The UV lamp may include the braid attachment <NUM>, or the braid attachment <NUM> may be separately coupled to the UV lamp.

In at least one embodiment, the method includes applying, at <NUM>, a conductive layer (such as the foil <NUM>) to at least a portion of the braid attachment (such as the braid attachment <NUM>) to provide a greater area of electrical contact and spread heat to prevent a thermal hotspot. Next, in at least one embodiment, the method includes applying, at <NUM>, a mechanical restraining device (such as the tape <NUM> and/or the clamp <NUM>) to secure the electrical braid and conductive layer together. The mechanical restraining device may be applied around at least a portion of the conductive layer. <FIG> illustrates an end view of a braid attachment <NUM> of a UV lamp <NUM>, according to an embodiment of the present disclosure. According the claimed subject matter, a compressive wrap, such as a fiberglass wrap <NUM>, is wrapped around the portion <NUM> of the braid attachment <NUM>. The fiberglass wrap <NUM> is first wrapped around the portion <NUM> of the braid attachment <NUM>. Ends <NUM> and <NUM> of the fiberglass wrap <NUM> are tied together in a knot <NUM>. At least a portion of the fiberglass wrap <NUM> is bonded with an epoxy <NUM>. For example, the knot <NUM> is bonded by an epoxy <NUM>, which may be cured at a temperature of <NUM> degrees C (<NUM> degrees F).

In at least one embodiment, the knot <NUM> including the epoxy <NUM> is spaced apart from the braid attachment <NUM>, such as by wrapped layers <NUM> of the fiberglass wrap <NUM>. That is, the wrapped layers <NUM> separate the knot <NUM>, which is bonded by the epoxy <NUM>, from the braid attachment <NUM> or other heat-generating portions of the UV lamp <NUM>. As such, the epoxy <NUM> is not directly subjected to high temperatures generated by the UV lamp <NUM>. Instead, the wrapped layers <NUM> provide a heat-dissipating buffer between the knot <NUM> and the braid attachment <NUM>. Accordingly, the epoxy <NUM> and the knot <NUM> may generally be below <NUM> degrees C when the UV lamp <NUM> is activated.

In at least one non-claimed embodiment, a thermoset, such as a Bismaleimide/cyanate ester composite resin thermoset may be used in place of, or in addition to, the epoxy <NUM>. The thermoset is able to withstand temperatures that exceed <NUM> degrees C.

<FIG> illustrates a perspective top view of the braid attachment <NUM> of the UV lamp <NUM>. A connecting electrical braid <NUM> connects to the braid attachment <NUM>. A mechanical restraining device or constraint, such as a fiberglass wrap, compressively secures at least a portion of the connecting electrical braid <NUM> to the braid attachment <NUM>.

In at least one embodiment, a conductive layer <NUM>, such as copper or aluminum foil, is secured over an end <NUM> of the connecting electrical braid <NUM> and the braid attachment <NUM>.

<FIG> illustrates a perspective top view of the conductive foil <NUM> secured over the portion of the braid attachment <NUM> and the connecting electrical braid <NUM>. <FIG> illustrates a lateral view of the braid attachment <NUM> of the UV lamp <NUM>. The conductive foil <NUM> may be positioned on opposite sides or surfaces of the braid attachment <NUM>. In at least one embodiment, the conductive foil <NUM> on the opposite surfaces may not connect together. Instead, a first conductive foil 420a is on one side or surface, and a second conductive foil 420b is on an opposite side or surface.

<FIG> illustrates a perspective view of the fiberglass wrap <NUM> being wrapped around the portion of the braid attachment <NUM>. The fiberglass wrap <NUM> may be wrapped around the conductive foil <NUM> and the portion of the braid attachment <NUM>.

<FIG> illustrates a perspective view of ends of the fiberglass wrap <NUM> being tied together in the knot <NUM>. <FIG> illustrates a perspective view of the epoxy <NUM> applied to the knot <NUM>. The epoxy <NUM> is an adhesive that bonds the knot <NUM>. As an example, the epoxy <NUM> is a high temperature adhesive that is configured to maintain an effective bond at temperatures that exceed <NUM> degrees C (<NUM> degrees F). As a non-limiting example, the epoxy <NUM> may be Loctite <NUM>.

<FIG> illustrates a perspective view of the fiberglass wrap <NUM> secured around the portion of the braid attachment <NUM>. The fiberglass wrap <NUM> compresses the conductive foil <NUM>, the portion of the braid attachment <NUM>, and the end of the connecting electrical braid <NUM> together, thereby providing a secure and reliable electrical connection.

<FIG> illustrates a schematic diagram of a clamp <NUM> secured around a portion of a UV lamp <NUM>, according to an embodiment of the present disclosure. The clamp <NUM> is secured around a portion of the UV lamp, such as the braid attachment <NUM>, as shown in <FIG>, for example. Referring to <FIG>, the clamp <NUM> may be secured over the fiberglass wrap <NUM>. Optionally, the clamp <NUM> may be used in place of the fiberglass wrap <NUM>.

The clamp <NUM> may be formed of a plastic or thermoplastic material. The clamp <NUM> includes ends <NUM> and <NUM> that may cooperate to secure together, such as through a latch, snap, or other such connection <NUM>. The clamp <NUM> may be a clip that is securely clamps around the portion of the UV lamp <NUM>.

<FIG> illustrates an axial cross-sectional view of the clamp <NUM> secured around the portion of the UV lamp <NUM>, according to an embodiment of the present disclosure. In at least one embodiment, the clamp <NUM> is formed of a resilient material, such as a plastic, that is configured to exert a compressive force into the portion of the UV lamp <NUM>, thereby securing an electrical connection therein.

The UV lamp <NUM> includes a bulb <NUM> connected to electrodes <NUM>. The clamp <NUM> may be secured around at least portions of the bulb <NUM> and the electrodes <NUM>.

In at least one embodiment, the clamp <NUM> includes expanded ends <NUM> connected together by a recessed connecting beam <NUM>. The expanded ends <NUM> have a greater height <NUM> than the recessed connecting beam <NUM>. The expanded ends <NUM> may connect to the recessed connecting beam <NUM> through smooth, curved transitions <NUM>.

A thickness <NUM> of the clamp <NUM> may vary around a perimeter. The varying thickness is configured to provide a desired stiffness and/or compressive force. For example, a thickness <NUM> of the recessed connecting beam <NUM> may be greater than a thickness of the expanded ends <NUM>. Optionally, the thickness <NUM> of the clamp <NUM> may be uniform throughout.

As shown, the recessed connecting beam <NUM> inwardly curves towards the UV lamp <NUM>, thereby forming inwardly-curved segments <NUM>. The inwardly-curved segments <NUM> curve towards one another and a central plane <NUM> of the UV lamp <NUM>. The inward curved of the recessed connecting beam <NUM> allows for a high preload and low spring rate, thereby mitigating differences in thermal expansion between the UV lamp <NUM> and the clamp <NUM>.

Alternatively, the clamp <NUM> may be sized and shaped differently than shown. For example, the clamp <NUM> may include a rectangular outer cross-section.

In at least one other embodiment, in addition to (or in place of) the clamp <NUM>, a resilient band may be used. For example, an elastomeric band may be used in addition to, or in place of, the clamp <NUM>.
