[0029] Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.Personal Cooling System

[0030] As shown in FIG. 1, a cooling system (e.g., cooling assembly, etc.), shown as personal cooling system 100, includes a head system (e.g., a head cooling assembly, etc.), shown as head cooling system 200, a fluid reservoir (e.g., a fluid tank, etc.), shown as fluidAtty. Dkt. No.: 141240-0104 reservoir system 300, configured to store cooling fluid (e.g., water, coolant, etc.) and selectively fluidly couple with the head cooling system 200 to supply the cooling fluid to the head cooling system 200, and a body system (e.g., a body cooling assembly, etc.), shown as body cooling system 400. In some embodiments, the personal cooling system 100 includes more or fewer components. When the head cooling system 200 is positioned on a head of a user (e.g., a person, etc.) of the personal cooling system 100, the fluid reservoir system 300 may be fluidly coupled to the head cooling system 200 to provide the cooling fluid to the head cooling system 200 to cool the head of the user. In some embodiments, the fluid reservoir system 300 is configured to selectively fluidly couple with the body cooling system 400 to supply the cooling fluid to the body cooling system 400. As a result, when the body cooling system 400 is positioned on a body of a user of the personal cooling system 100, the fluid reservoir system 300 may be fluidly coupled to the body cooling system 400 to provide the cooling fluid to the body cooling system 400 to cool the body of the user.Head Cooling System

[0031] As shown in FIGS. 2-10, the head cooling system 200 includes a cap portion (e.g., head piece, etc.), shown as cooling cap 210, configured to be positioned on (e.g., in contact with, etc.) a head of a user of the personal cooling system 100, shown as head 10; an elastic portion (e.g., biasing portion, an elastic area, etc.), shown as elastic band 250, coupled to (e.g., disposed within) or along a lower edge of the cooling cap 210 and configured to contract around the head 10 when the cooling cap 210 is positioned on the head 10 to prevent unintended removal of the cooling cap 210 from the head 10; and an inlet portion, shown as inlet assembly 260, coupled to the cooling cap 210 and configured to selectively fluidly couple with the fluid reservoir system 300 to receive the cooling fluid from the fluid reservoir system 300. In some embodiments, a larger portion of the cooling cap 210 is elastic or the outer / inner materials of the cooling cap 210 are elastic such that the elastic band 250 may not be included. In some embodiments, the head cooling system 200 does not include the inlet assembly 260. For example, the cooling cap 210 may be configured to couple with the fluid reservoir system 300 to receive the cooling fluid from the fluid reservoir system 300 without the inlet assembly 260. As another example, the cooling cap 210 may not be configured to couple with the fluid reservoir system 300 and the cooling capAtty. Dkt. No.: 141240-0104210 may received the cooling fluid by being submerged in the cooling fluid and / or having the cooling fluid be poured over the cooling cap 210.

[0032] In some embodiments, the head cooling system 200 is an under-helmet cooling system that is configured to be positioned on the head 10 of the user under a helmet (e.g., an American football helmet, a bike helmet, a baseball helmet, a motorsports racing helmet, a boxing helmet, a construction helmet, etc.) such that the user can wear the head cooling system 200 and the helmet at the same time. As a result, when the user is wearing a helmet over the head cooling system 200, the head cooling system 200 may receive the cooling fluid from the fluid reservoir system 300 and provide the cooling fluid to the head 10 of the user without the user having to remove the helmet. For example, when a user is playing American football, the user may have a short amount of time to cool down between plays. The fluid reservoir system 300 may be fluidly coupled to the head cooling system 200 to provide the cooling fluid from the fluid reservoir system 300 to the head 10 of the user through the head cooling system 200, such that the user is cooled by the cooling fluid without having to remove their helmet and can return to the field for the next play.

[0033] As shown in FIGS. 4, 5, and 7-10, the cooling cap 210 includes a first portion, shown as head portion 212, that defines a cavity (e.g., compartment, opening, etc.), shown as head cavity 214, configured to receive a top portion of the head 10 of the user (e.g., the crown of the head 10, etc.) when the cooling cap 210 is positioned on the head 10 of the user. In some embodiments, the size of the head cavity 214 may vary based on an intended user of the head cooling system 200. For example, a first of the head cavities 214 may have a first size for a first of the head cooling systems 200 configured to be positioned on the head 10 of a child, a second of the head cavities 214 may have a second size for a second of the head cooling systems 200 configured to be positioned on the head 10 of a teenager, and a third of the head cavities 214 may have a third size for a third of the head cooling systems 200 configured to be positioned on the head 10 of an adult. In other embodiments, the head cooling system 200 may be configured as a one size fits all head cooling system that defines a single size of the head cavity 214. In still other embodiments, the size of the head cavity 214 is user adjustable.

[0034] As shown in FIGS. 4, 5, 7, and 10 the cooling cap 210 includes a first layer (e.g., an inner fabric layer, an inner liner, a bottom layer, a head liner, etc.), shown as inner layer 220, positioned on an inward facing side of the cooling cap 210 and defining the headAtty. Dkt. No.: 141240-0104 cavity 214, a second layer (e.g., an outer fabric layer, an outer liner, a top layer, an exterior layer, etc.), shown as outer layer 230, positioned on an opposing outward facing side of the cooling cap 210, and an intermediate layer (e.g., padding layer, cooling reservoir layer, cooling compartment layer, etc.), shown as pad 240, positioned between the inner layer 220 and the outer layer 230 (e.g., positioned on a second side of the inner layer 220 opposite a first side of the inner layer 220 defining the head cavity 214, positioned on an inward side of the outer layer 230 opposite an outward side of the outer layer 230, etc.). The cooling cap 210 includes an end portion, shown as end piece 222, coupled between a first edge (e.g., a first end, an inner end, etc.), shown as inner edge 224, of the inner layer 220 and a second edge (e.g., a second end, an outer end, etc.), shown as outer edge 232, of the outer layer 230. By way of example, the end piece 222 may be coupled to the inner edge 224 of the inner layer 220 extending around an outside of the inner layer 220 and to the outer edge 232 of the outer layer 230 extending around an outside of the outer layer 230 such that the pad 240 is surrounded by the inner layer 220, the end piece 222, and the outer layer 230. In other embodiments, the inner edge 224 of the inner layer 220 is directly coupled to the outer edge 232 of the outer layer 230 to couple the inner layer 220 to the outer layer 230. By way of example, the inner edge 224 of the inner layer 220 may be directly coupled to the outer edge 232 of the outer layer 230 (e.g., sewed together, heat sealed, ultrasonically welded, etc.) such that the pad 240 is surrounded by the inner layer 220 and the outer layer 230. In other embodiments, the cooling cap 210 includes additional layers. In still other embodiments, the cooling cap 210 does not include the inner layer 220 and / or the outer layer 230. By way of example, when the cooling cap 210 does not include the inner layer 220, the pad 240 may be positioned inward of the outer layer 230, be coupled to the outer layer 230, and define the head cavity 214. By way of another example, when the cooling cap 210 does not include the outer layer 230, the pad 240 may be positioned outward of the inner layer 220 and be coupled to the inner layer 220.

[0035] According to an exemplary embodiment, the inner layer 220 and the outer layer 230 are formed from a permeable or semi-permeable materials (e.g., liquid permeable, liquid semi-permeable, fluid permeable materials, water permeable, materials with openings to allow fluid to pass through the material, etc.). By way of example, the inner layer 220 and the outer layer 230 may be formed from a polyester or polypropylene fabric that allows for liquid to pass through the inner layer 220 and the outer layer 230. As a result, the cooling liquid received by the head cooling system 200 may pass through the outer layerAtty. Dkt. No.: 141240-0104230 and the inner layer 220 and be provided to the head 10 of the user received by the head cavity 214 to cool the head 10 of the user (e.g., cooling liquid could be poured over the head cooling system 200 and seep through to head 10 of the user via gravity). Additionally, sweat produced on the head 10 of the user may be absorbed by the head cooling system 200 through the inner layer 220 and may be expelled from the head cooling system 200 through the outer layer 230, preventing the sweat from accumulating on the head 10 of the user. According to an exemplary embodiment, the inner layer 220 is formed from a permeable material that is configured to control a release of fluid through the inner layer 220. For example, the permeable material may be configured to allow for a certain flow rate of fluid through the inner layer 220. In other embodiments, the inner layer 220 is formed from a permeable material and the outer layer 230 is formed from a non-permeable material. As a result, when the cooling liquid is received by the head cooling system 200 from the fluid reservoir system 300, the cooling liquid may pass through the inner layer 220 and be provided to the head 10 of the user received by the head cavity 214 and the cooling liquid may not pass through the outer layer 230 such that all of the cooling liquid received by the head cooling system 200 is provided to the head 10 of the user. In still other embodiments, the inner layer 220 and the outer layer 230 are formed from a non-permeable material (e.g., a fluid impermeable material, at least partially from a fluid impermeable material, etc.). As a result, when the cooling liquid is received by the head cooling system 200 from the fluid reservoir system 300, the cooling liquid may be retained between the inner layer 220 and the outer layer 230 to remove heat from the head 10 within the head cavity 214 and then be returned to the fluid reservoir system 300 (e.g., by a fluid return system, etc.). The cooling liquid may be recirculated (e.g., passively recirculated, actively recirculated, etc.) between the head cooling system 200 and the fluid reservoir system 300 to facilitate cooling of the head 10 within the head cavity 214. By way of example, the fluid reservoir system 300 may provide the cooling fluid to the head cooling system 200, the cooling fluid may flow between the inner layer 220 and the outer layer 230 and received heat from the head 10 within the head cavity 214, the head cooling system 200 may return the cooling fluid to the fluid reservoir system 300 (e.g., via a fluid return line, etc.), the fluid reservoir system 300 may remove (e.g., dissipate, etc.) the heat from the cooling fluid, and the fluid reservoir system 300 may return the cooling fluid to the head cooling system 200.

[0036] In some embodiments, the inner layer 220 and / or the outer layer 230 are formed from, coated with, or lined with a soft material (e.g., materials with low hardness, nylon,Atty. Dkt. No.: 141240-0104 polyester, etc.) to increase a comfort of the user when the head 10 of the user is supporting the head cooling system 200. Specifically, as shown in FIGS. 4, 5, and 10 an inner surface, shown as head contacting surface 226, of the inner layer 220 can be coated with a soft foam (e.g., an open-cell foam, polyurethane foam, etc.) such that the soft foam contacts the head 10 of the user when the head 10 is received by the head cavity 214 to increase a comfort of the user. In some embodiments, the inner layer 220 and / or the outer layer 230 are formed from a flexible material (e.g., materials that bed easily, etc.). For example, the inner layer 220 may be formed from a polyester fabric to allow for the inner layer 220 to deform when the head 10 of the user is received by the head cavity 214 to allow for the head contacting surface 226 of the inner layer 220 to match an outer profile of the head 10. As another example, the outer layer 230 may be formed from a polyester fabric to allow for the outer layer 230 to deform when a helmet is positioned on top of the head cooling system 200 to allow for an outer surface of the outer layer 230 to match an inner profile of the helmet. In some embodiments, the inner layer 220 and / or the outer layer 230 are formed from a lightweight material (e.g., lighter than materials used in a helmet, etc.) to reduce a weight of the head cooling system 200.

[0037] In some embodiments, the inner layer 220 and / or the outer layer 230 are formed from materials that dry quickly (e.g., materials with moisture wicking properties, materials that do not retain liquids, etc.). By way of example, the inner layer 220 and / or the outer layer 230 may be formed from polyester, nylon, or another synthetic fiber that dries faster than cotton. As a result, the inner layer 220 and / or the outer layer 230 may dry quickly after the cooling fluid passes through the inner layer 220 and / or the outer layer 230. Additionally, the inner layer 220 and / or the outer layer 230 may dry quickly after the sweat produced on the head 10 of the user is absorbed by the inner layer 220 and / or the outer layer 230. In some embodiments, the inner layer 220 and / or the outer layer 230 are formed from and / or coated with a hydrophobic material (e.g., a material that repels fluids, a material that repels water, etc.). For example, the inner layer 220 and / or the outer layer 230 may be formed from a treated polyester that allows for the inner layer 220 and / or the outer layer 230 to repel water to prevent the cooling fluid and / or sweat from accumulating in the inner layer 220 and / or the outer layer 230.

[0038] According to an exemplary embodiment, the pad 240 is formed out of a cushioning material (e.g., ethylene vinal acetate foam, memory foam, viscoelastic foam, etc.)Atty. Dkt. No.: 141240-0104 configured to absorb a portion of an impact force applied to the head cooling system 200. By way of example, the pad 240 may be formed out of a polyurethane foam that absorbs the portion of the impact force applied to the head cooling system 200 by deforming under the impact force. As a result, when the user of the head cooling system 200 is hit on the head 10 with an impact force (e.g., due to a collision with another person, due to a ball hitting the head 10 of the user, etc.), the head cooling system 200 may absorb a portion of the impact force to protect the head 10 of the user.

[0039] In some embodiments, the pad 240 is formed from a soft material (e.g., materials with a low hardness, polyurethane, etc.) to increase a comfort of the user when the head 10 of the user is supporting the head cooling system 200. The pad 240 may additionally increase a comfort of the user when the head of the user is supporting the head cooling system 200 and a helmet positioned on top of the head cooling system 200 relative to when the head 10 is only supporting the helmet. By way of example, the pad 240 may provide additional cushioning between the head 10 and the helmet to increase the comfort of the user. In some embodiments, the pad 240 is formed from a light-weight material (e.g., lighter than materials used in a helmet, etc.) to reduce the weight of the head cooling system 200.

[0040] In some embodiments, the pad 240 is formed from materials that dry quickly (e.g., materials with moisture wicking properties, materials that do not retain liquids, etc.). By way of example, the pad 240 may be formed from fluid resistant polyurethane configured to expel fluid absorbed by the pad 240 to quickly dry the pad 240 or prevent the ingress of fluid therein. In some embodiments, the pad 240 is formed from and / or coated with a hydrophobic material (e.g., a material that repels fluids, a material that repels water, etc.). For example, the pad 240 may be formed from a hydrophobic treated polyurethane that repels water away from the pad 240 to prevent the cooling fluid received by the head cooling system 200 from the fluid reservoir system 300 or sweat received by the head cooling system 200 from the head 10 from accumulating in the pad 240.

[0041] As shown in FIGS. 4, 5, 7, and 10 the inner layer 220 and the pad 240 collectively (e.g., cooperatively, etc.) define a first gap (e.g., first potential layer, a first potential space, an inner potential space, etc.), shown as inner gap layer 242, positioned between the inner layer 220 and the pad 240. The inner gap layer 242 is configured to receive fluids passing through the inner layer 220 and / or the pad 240. By way of example, the inner gap layer 242 may receive the cooling fluid provided to the head cooling system 200 from the fluidAtty. Dkt. No.: 141240-0104 reservoir system 300 through the pad 240 and distribute the cooling fluid across the inner layer 220 such that the cooling fluid can be evenly provided to the head 10 of the user through the inner layer 220. As another example, the inner gap layer 242 may receive the sweat provided to the head cooling system 200 from the head 10 of the user through the inner layer 220 and provide the sweat to the pad 240 such that the sweat is moved away from the head 10. In some embodiments, the inner gap layer 242 is formed when the fluids are provided between the inner layer 220 and the pad 240. By way of example, the inner layer 220 may contact the pad 240 until a fluid is provided between the inner layer 220 and the pad 240. Once the fluid is provided between the inner layer 220 and the pad 240, the inner layer 220 may separate from the pad 240 to form the inner gap layer 242 to receive the fluid and allow for the fluid to be transferred between the inner layer 220 and the pad 240. In other embodiments, the inner gap layer 242 is always formed between the inner layer 220 and the pad 240.

[0042] As shown in FIGS. 4, 5, 7, and 10 the outer layer 230 and the pad 240 collectively define an outer gap (e.g., a second potential layer, a second potential space, an outer potential layer, etc.), shown as outer gap layer 244, positioned between the outer layer 230 and the pad 240. The outer gap layer 244 is configured to receive fluids passing through the outer layer 230 and / or the pad 240. By way of example, the outer gap layer 244 may receive the cooling fluid provided to the head cooling system 200 through the outer layer 230 and distribute the cooling fluid across the pad 240 such that the cooling fluid can be evenly provided through the pad 240 to the inner gap layer 242. As another example, the outer gap layer 244 may receive the sweat provided to the head cooling system 200 from the head 10 of the user through the pad 240 and provide the sweat to the outer layer 230 to be expelled from the head cooling system 200 such that the sweat does not accumulate in the head cooling system 200. In some embodiments, the outer gap layer 244 is formed when the fluids are provided between the outer layer 230 and the pad 240. By way of example, the outer layer 230 may contact the pad 240 until a fluid is provided between the outer layer 230 and the pad 240. Once the fluid is provided between the outer layer 230 and the pad 240, the outer layer 230 may separate from the pad 240 to form the outer gap layer 244 to receive the fluid and allow for the fluid to be transferred between the inner layer 220 and the pad 240. In other embodiments, the outer gap layer 244 is always formed between the outer layer 230 and the pad 240.Atty. Dkt. No.: 141240-0104

[0043] As shown in FIGS. 4, 5, 7, and 10 the pad 240 defines a plurality of openings (e.g., columns, fluid columns, fluid transport openings, channels, etc.), shown as fluid openings 246, extending through the pad 240. The fluid openings 246 are fluidly coupled between the outer gap layer 244 and the inner gap layer 242 to allow fluid to be transferred between the inner gap layer 242 and the outer gap layer 244 through the pad 240. By way of example, each of the fluid openings 246 may be configured as circular columnar openings extending through the pad 240 to allow for fluids to be transferred between the inner gap layer 242 and the outer gap layer 244. In other embodiments, the pad 240 defines a single of the fluid openings 246 extending through the pad 240. In still other embodiments, the pad 240 does not define the fluid openings 246 (e.g., when fluids can pass through the pad 240, etc.). By way of example, the pad 240 may not define the fluid openings 246 when the pad 240 is formed from a fluid permeable material that allows for fluids to flow through the pad 240 between the inner gap layer 242 and the outer gap layer 244.

[0044] As shown in FIGS. 2-8, the elastic band 250 is positioned around an entrance to the head cavity 214. The elastic band 250 may be configured to bias the entrance to the head cavity 214 closed. By way of example, the elastic band 250 may be formed from an elastic material that is positioned around the entrance to the head cavity 214 and bias the entrance to the head cavity 214 toward a closed configuration where the entrance to the head cavity 214 is smaller than when the entrance to the head cavity 214 is in an open configuration. When the head 10 of the user is being received by the head cavity 214, the elastic band 250 may stretched such that the entrance to the head cavity 214 is in the open configuration and the head 10 can pass into the head cavity 214 through the entrance to the head cavity 214. Once the head 10 has been received by the head cavity 214, the elastic band 250 may contract around the head 10 to prevent accidental removal of the head cooling system 200.

[0045] As shown in FIGS. 3-7 and 10, the inlet assembly 260 includes an inlet, shown as inlet valve 262, coupled to and extending through the outer layer 230, a retention portion, shown as retention bar 264, coupled to the outer layer 230 proximate the inlet valve 262, and an attachment interface, shown as strap interface 266, coupled to the outer layer 230. In some embodiments, the inlet assembly 260 is configured as a retractable inlet assembly that is configured to selectively retract below a top surface of the outer layer 230. For example, when the fluid reservoir system 300 is not fluidly coupled to the inlet assembly 260, the inlet assembly 260 may retract below the top surface of the outer layer 230 such that theAtty. Dkt. No.: 141240-0104 inlet assembly 260 does not extend above the top surface of the outer layer 230. As a result, the helmet may be positioned on top of the head cooling system 200 without contacting the inlet assembly 260 (e.g., only contacting the outer layer 230, etc.). In other embodiments, the inlet assembly 260 is configured as a stationary inlet assembly and does not move relative to the outer layer 230.

[0046] The inlet valve 262 is configured to selectively fluidly couple with the fluid reservoir system 300 to allow for the fluid reservoir system 300 to provide fluid to the outer gap layer 244. As a result, when the portion of the fluid reservoir system 300 is fluidly coupled to the inlet valve 262, the cooling fluid provided to the head cooling system 200 from the fluid reservoir system 300 may be received by the outer gap layer 244 via the inlet valve 262. In other embodiments, the inlet valve 262 extends through the outer layer 230 and the pad 240 and is configured to selectively fluidly couple with the fluid reservoir to allow for the fluid reservoir system 300 to directly provide fluid to the inner gap layer 242. In some embodiments, the inlet valve 262 is configured as a one way valve. By way of example, the inlet valve 262 may be configured as a one way valve that allows for fluid to flow through the inlet valve 262 in a direction towards the outer gap layer 244 and prevents fluid from flowing through the inlet valve 262 in a direction away from the outer gap layer 244. As a result, the inlet valve 262 may allow for a flow of fluid into the head cooling system 200 through the inlet valve 262 and may prevent a flow of fluid out of the head cooling system 200 through the inlet valve 262. In some embodiments, the inlet assembly 260 does not include the inlet valve 262. For example, the outer layer 230 may be configured to receive fluid from the fluid reservoir system 300 across an outer surface of the outer layer 230 and provide the fluid to the outer gap layer 244 through the outer layer 230 (e.g., when the outer layer 230 is fluid permeable, etc.). In some embodiments, the inlet assembly 260 includes an outlet valve configured to selectively fluidly couple with the fluid reservoir system 300 to allow for the head cooling system 200 to provide fluid to the fluid reservoir system 300 (e.g., when the cooling fluid is recirculated between the head cooling system 200 and the fluid reservoir system 300, etc.). By way of example, when the portion of the fluid reservoir system 300 is fluidly coupled to the outlet valve of the inlet assembly 260, the cooling fluid may be provided from the outer gap layer 244 and / or the inner gap layer 242 of the head cooling system 200 to the fluid reservoir system 300.Atty. Dkt. No.: 141240-0104

[0047] According to the exemplary embodiment shown in FIGS. 3-7 and 10, the inlet valve 262 is coupled to a top portion of the outer layer 230 (e.g., an uppermost portion, a crown portion, etc.). In other embodiments, the inlet valve 262 is coupled to a side portion of the outer layer 230 and / or a rearward portion of the outer layer 230 such that the fluid reservoir system 300 may fluidly couple to the inlet valve 262 when the helmet is positioned on top of the head cooling system 200 and covers the top portion of the outer layer 230.

[0048] As shown in FIGS. 3-7 and 10, the retention bar 264 is positioned between the inlet valve 262 and the strap interface 266. The retention bar 264 is configured to engage a portion of the fluid reservoir system 300 to prevent the portion of the fluid reservoir system 300 from moving relative to the outer layer 230. In some embodiments, the retention bar 264 extends upward from the outer layer 230 higher than the inlet valve 262. In other embodiments, the inlet assembly 260 does not include the retention bar 264.

[0049] As shown in FIGS. 6 and 7, the strap interface 266 is positioned rearward of the retention bar 264. The strap interface 266 is configured to removably couple to a portion of the fluid reservoir system 300 to prevent the portion of the fluid reservoir system 300 from moving relative to the outer layer 230. In some embodiments, the strap interface 266 includes a strap configured to wrap at least partially around the portion of the fluid reservoir system 300 to prevent the portion of the fluid reservoir system 300 from moving relative to the outer layer 230. In other embodiments, the inlet assembly 260 does not include the strap interface 266.

[0050] As shown in FIG. 4, when the inlet valve 262 receives the cooling fluid from the fluid reservoir system 300, the inlet valve 262 provides the cooling fluid to the outer gap layer 244. In other embodiments, when the outer layer 230 receives the cooling fluid on the outer surface of the outer layer 230 from the fluid reservoir system 300, the outer layer 230 provides the cooling fluid to the outer gap layer 244 through the outer layer 230 (e.g., when the outer layer 230 is liquid permeable, etc.). The outer gap layer 244 distributes the cooling fluid across a top surface of the pad 240. The cooling fluid then flows from the outer gap layer 244 through the pad 240 through the fluid openings 246 defined by the pad 240 and into the inner gap layer 242. The inner gap layer 242 distributes the cooling fluid across a top surface of the inner layer 220 such that the cooling fluid can be provided to the head cavity 214 through the inner layer 220.Atty. Dkt. No.: 141240-0104

[0051] According to the exemplary embodiment shown in FIG. 5, the cooling cap 210 includes a plurality of the pads 240 (e.g., intermediate layer portions, etc.) positioned between the inner layer 220 and the outer layer 230 and extending in a lateral direction from a front end of the cooling cap 210 to a rear end of the cooling cap 210. The plurality of the pads 240 extending in the lateral direction may increase the amount of impact force that can be absorbed by the head cooling system 200. For example, the cooling cap 210 may include a first of the pads 240 extending in the lateral direction and positioned on a first side of the cooling cap 210, a second of the pads 240 extending in the lateral direction and positioned on an opposing second side of the cooling cap 210, a third of the pads 240 extending in the lateral direction and positioned between the first of the pads 240 and the second of the pads 240, a fourth of the pads 240 extending in the lateral direction and positioned between the first of the pads 240 and the third of the pads 240, and a fifth of the pads 240 extending in the lateral direction and positioned between the second of the pads 240 and the third of the pads 240. In some embodiments, the pads 240 extending in the lateral direction may extend from the front end of the cooling cap 210 to the rear end of the cooling cap 210. In other embodiments, the cooling cap 210 may include a plurality of the pads 240 extending in the lateral direction positioned between the front end of the cooling cap 210 and the rear end of the cooling cap 210. For example, a first of the pads 240 may extend a first length rearward from the front end of the cooling cap 210 (e.g., rearward to a coronal plane of the head 10 of the user, etc.) and a second of the pads may extend a second length forward from the rear end of the cooling cap 210 (e.g., forward to the coronal plane of the head 10 of the user, etc.).

[0052] According to the exemplary embodiment shown in FIG. 5, the inner layer 220 and the outer layer 230 extend toward each other in between each of the plurality of the pads 240 extending in the lateral direction (e.g., in between adjacent of the plurality of the pads 240, etc.). As the inner layer 220 and the outer layer 230 extend toward each other, the inner layer 220 and the outer layer 230 may form lateral fixations (e.g., first plurality of fixation points, lateral fixation points, lateral fixation lines, etc.) at locations where a distance between the inner layer 220 and the outer layer 230 is minimized. By way of example, the inner layer 220 and the outer layer 230 may form the lateral fixations in between each of the plurality of the pads 240 extending in the lateral direction. At each of the lateral fixations, a first distance between the inner layer 220 and the outer layer 230 is less than a second distance between the inner layer 220 and the outer layer 230 at locations where the pads 240Atty. Dkt. No.: 141240-0104 are positioned between the inner layer 220 and the outer layer 230. At each of the lateral fixations, the inner gap layer 242 may intersect the outer gap layer 244 to allow for fluids to directly flow between the inner gap layer 242 and the outer gap layer 244. As a result, fluids may flow through the outer gap layer 244 towards the lateral fixations and into the inner gap layer 242 without flowing through the fluid openings 246.

[0053] According to the exemplary embodiment shown in FIG. 7, the cooling cap 210 includes a plurality of the pads 240 positioned between the inner layer 220 and the outer layer 230 and extending in a longitudinal direction from a first side (e.g., a left side, a right side, etc.) of the cooling cap 210 to an opposing second side of the cooling cap 210. The plurality of the pads 240 extending in the longitudinal direction may increase an amount of the impact force applied on the head cooling system 200 that can be absorbed by the pads 240. For example, the cooling cap 210 may include a first of the pads 240 extending in the longitudinal direction and positioned on a rearward side of the cooling cap 210, a second of the pads 240 extending in the longitudinal direction and positioned on a forward side of the cooling cap 210, and a third of the pads 240 extending in the longitudinal direction and positioned between the first of the pads 240 and the second of the pads 240. In some embodiments, the pads 240 extending in the longitudinal direction may extend from the first side of the cooling cap 210 to the opposing second side of the cooling cap 210. In other embodiments, the cooling cap 210 may include a plurality of the pads 240 extending in the longitudinal direction positioned between the first side of the cooling cap 210 and the opposing second side of the cooling cap 210. For example, a first of the pads 240 may extend a first length in the lateral direction from the first side of the cooling cap 210 toward the opposing second side of the cooling cap 210 (e.g., from the first side of the cooling cap 210 to the sagittal plane of the head 10 of the user, etc.) and a second of the pads 240 may extend a second length in the lateral direction from the opposing second side of the cooling cap 210 toward the first side of the cooling cap 210 (e.g., from the opposing second side of the cooling cap 210 to the sagittal plane of the head 10 of the user, etc.).

[0054] According to the exemplary embodiment shown in FIG. 7, the inner layer 220 and the outer layer 230 may extend toward each other in between each of the plurality of the pads 240 extending in the longitudinal direction. As the inner layer 220 and the outer layer 230 extend toward each other, the inner layer 220 and the outer layer 230 may form longitudinal fixations (e.g., a second plurality of fixation points, longitudinal fixation points,Atty. Dkt. No.: 141240-0104 longitudinal fixation lines, etc.) at locations where a distance between the inner layer 220 and the outer layer 230 is minimized. By way of example, the inner layer 220 and the outer layer 230 may form the longitudinal fixations in between each of the plurality of the pads 240 extending in the longitudinal direction. At each of the longitudinal fixations, a first distance between the inner layer 220 and the outer layer 230 may be less than a second distance between the inner layer 220 and the outer layer 230 at locations where the pads 240 are positioned between the inner layer 220 and the outer layer 230. At each of the longitudinal fixations, the inner gap layer 242 may intersect the outer gap layer 244 to allow for fluids to directly flow between the inner gap layer 242 and the outer gap layer 244. As a result, fluids may flow through the outer gap layer 244 towards the longitudinal fixations and into the inner gap layer 242 without flowing through the fluid openings 246. It should be understood that the pad features of the cooling cap 210 shown in FIGS. 5 and 7 may be used in a single cooling cap.

[0055] In some embodiments, the cooling cap 210 includes a brim (e.g., a perpendicular brim, etc.) extending outward from the head portion 212 of the cooling cap 210. The end piece 222 may be positioned along the brim of the cooling cap 210 such that the outer edge 232 of the outer layer 230 and / or the inner edge 224 of the inner layer 220 extend outward from the head portion 212 of the cooling cap 210 along at least a portion of the brim of the cooling cap 210. As a result, a portion of the environment directly surrounding the head 10 of the user may be cooled by the cooling fluid provided by the portion of the inner layer 220 extending along the at least the portion of the brim of the cooling cap 210 to the environment surrounding the head 10 to form a temperature barrier between the portion of the environment directly surrounding the head 10 and a remainder of the environment.

[0056] According to the exemplary embodiment shown in FIGS. 4, 5, and 7, the cooling cap 210 has a thickness t. The thickness t of the cooling cap 210 may be a distance from the head contacting surface 226 of the inner layer 220 to an outside surface of the outer layer 230. In some embodiments, the thickness t is the distance between the head contacting surface 226 of the inner layer 220 to the outside surface of the outer layer 230 when there is not fluid positioned in the inner gap layer 242 and / or the outer gap layer 244 (e.g., when the outer layer 230 contacts the pad 240, when the inner layer 220 contacts the pad 240, etc.). In other embodiments, the thickness t is the distance between the head contacting surface 226 of the inner layer 220 to the outside surface of the outer layer 230 when fluid is positionedAtty. Dkt. No.: 141240-0104 in the inner gap layer 242 and / or the outer gap layer 244. In some embodiments, the thickness t is in a range between about 1.0 cm and about 4.0 cm (0.59 inches and 1.57 inches). According to an exemplary embodiment, the thickness t is in a range between about 1.5 cm and about 2 cm (0.59 inches and 0.787 inches). As a result of the thickness t, the cooling cap 210 may be positioned on the head 10 of the user under the helmet.

[0057] According to the exemplary embodiment shown in FIG. 8, the cooling cap 210 defines a first opening (e.g., a first aperture, etc.), shown as head opening 270, configured to provide access to a portion of the head 10 of the user through the cooling cap 210 (e.g., through the inner layer 220, through the outer layer 230, through the pad 240, etc.) when the cooling cap 210 is positioned on the head 10 of the user. In some embodiments, the head opening 270 is positioned on a forward portion of the cooling cap 210 and is configured to provide access to a forward portion of the head 10 of the user (e.g., a portion of the head 10 forward of the coronal plane of the head 10, a forward portion of the crown of the head 10, a forehead of the head 10, etc.) through the cooling cap 210 when the cooling cap 210 is positioned on the head 10 of the user. By way of example, the head opening 270 may be positioned on the forward portion of the cooling cap 210 when the head cooling system 200 is configured to be used by a user playing soccer such that the head 10 of the user can contact the soccer ball through the head opening 270 (e.g., when the user is heading the soccer ball, etc.). In some embodiments, the head opening 270 is positioned on a rearward portion of the cooling cap 210 and is configured to provide access to a rearward portion of the head 10 of the user (e.g., a portion of the head 10 rearward of the coronal plane of the head 10, a rearward portion of the crown of the head 10, etc.) through the cooling cap 210 when the cooling cap 210 is positioned on the head 10 of the user. By way of example, the head opening 270 may be positioned on the rearward portion of the cooling cap 210 such that hair (e.g., a ponytail, a bun, etc.) on the head 10 of the user may extend outward from the head 10 through the head opening 270. In some embodiments, the cooling cap 210 defines a plurality of the head openings 270 (e.g., a first of the head openings 270 on a forward portion of the cooling cap 210, a second of the head openings 270 on a rearward portion of the cooling cap 210, etc.). In some embodiments, the head opening 270 is configured to accommodate a helmet when the helmet is positioned on top of the head cooling system 200. By way of example, the head opening 270 may align with and receive a portion of the helmet when the helmet is positioned on top of the head cooling system 200 such that the helmet may contact the head 10 of the user.Atty.

In some embodiments, the brim 272 is positioned on a forward portion of the cooling cap 210 and is configured to shade a face portion of the head 10 of the user when the cooling cap 210 is positioned on the head 10 of the user. By way of example, the brim 272 may be coupled to the head portion 212 and extend outward from the head portion 212 in a forward direction to shade the face of the head 10 of the user. In some embodiments, the brim 272 is a wide brim that extends fully around the cooling cap 210 to shade multiple portions of the head 10 of the user when the cooling cap 210 is positioned on the head 10 of the user. By way of example, the brim 272 may extend around the head portion 212 of the cooling cap 210 (e.g., fully around, partially around, more than 50% around, etc.), be coupled to the head portion 212, and extend outward in multiple directions from the head portion 212 to shade multiple portions of the head 10 of the user.

By way of example, when the neck flap 280 extends rearward from the head portion 212 of the cooling cap 210 and the end piece 222 is positioned along the neck flap 280, the outer layer 230 and the inner layer 220 may extend rearward from the head portion 212 of the cooling cap 210 along the neck flap 280. As a result of the outer layer 230 and the inner layer 220 extending along the neck flap 280, the neck of the user and / or a portion of the environment directly surrounding the neck of the user may be cooled by the cooling fluid provided by the portion of the inner layer 220 extending along the at least the portion of the neck flap 280 to the environment surrounding the neck to form a temperature barrier between the portion of the environment directly surrounding the neck and a remainder of the environment.

[0062] According to the exemplary embodiment shown in FIGS. 9 and 10, the cooling cap 210 defines a second opening (e.g., a second aperture), shown as hair opening 290, configured to receive hair, shown as pony tail 12, extending from the head 10 of the user when the cooling cap 210 is positioned on the head 10 of the user (e.g., through the inner layer 220, through the outer layer 230, through the pad 240, etc.) so that the pony tail 12 may be at least partially positioned outside of the head cavity 214. In some embodiments, the hair opening 290 is positioned on a rearward portion of the cooling cap 210 and is configured to provide access to a rearward portion of the head 10 of the user (e.g., a portion of the head 10 rearward of the coronal plane of the head 10, a rearward portion of the crown of the head 10, a back of the head 10, etc.) through the cooling cap 210 when the cooling cap 210 is positioned on the head 10 of the user.

Dkt. No.: 141240-0104 the pony tail 12 of the user extending from the head 10 of the user may be positioned outside of the head cavity 214 of the cooling cap 210.Fluid Reservoir System

[0063] As shown in FIGS. 1 and 12-14, the fluid reservoir system 300 includes a reservoir (e.g., tank, fluid compartment, etc.), shown as fluid reservoir 310, configured to receive the cooling fluid, a membrane, shown as fluid membrane 320, positioned inside of the fluid reservoir 310, and a hose assembly, shown as outlet hose assembly 330, fluidly coupled to the fluid reservoir 310 and configured to receive the cooling fluid from the fluid reservoir 310. In some embodiments, the fluid reservoir 310 includes more or fewer components.

[0064] According to the exemplary embodiment shown in FIG. 11, the fluid reservoir system 300 is configured as a portable fluid reservoir system. By way of example, the fluid reservoir system 300 may be configured as a backpack configured to be worn by the user of the personal cooling system 100 while the user moves with the fluid reservoir system 300. In some embodiments, the fluid reservoir system 300 is configured to be worn by the user of the personal cooling system 100 while the head 10 of the user is received by the head cavity 214 of the head cooling system 200 to allow for the fluid reservoir system 300 to provide the cooling fluid to the head cooling system 200 while the user is moving. For example, the user of the personal cooling system 100 may carry the fluid reservoir system 300 while moving from a first location to a second location such that the fluid reservoir system 300 is able to provide the cooling fluid to the head cooling system 200 to provide the cooling fluid to the head 10 of the user while the user is moving from the first location to the second location.

[0065] As shown in FIGS. 12-14, the fluid reservoir 310 defines a cavity, shown as reservoir cavity 312, configured to store the cooling fluid and an outlet, shown as outlet port 314, extending through the fluid reservoir 310 to provide access to the reservoir cavity 312. The outlet port 314 is configured to align with and receive the outlet hose assembly 330 to provide the cooling fluid from the fluid reservoir 310 to the outlet hose assembly 330. In some embodiments, the fluid reservoir 310 defines an inlet extending through the fluid reservoir 310 to provide access to the reservoir cavity 312 and configured to receive the cooling fluid and provide the cooling fluid into the fluid reservoir 310 to fill the fluidAtty. Dkt. No.: 141240-0104 reservoir 310 with the cooling fluid. In some embodiments, the fluid reservoir 310 is configured to limit heat transfer between the reservoir cavity 312 and a surrounding environment. For example, the fluid reservoir 310 may be formed from a material with a low thermal conductivity (e.g., polystyrene, polyurethane, etc.) which limits an amount of heat transferred between the reservoir cavity 312 and the surrounding environment.

[0066] As shown in FIGS. 12-14, the fluid membrane 320 extends across the fluid reservoir 310 and separates the reservoir cavity 312 into a first compartment (e.g., a first section, a fluid cavity portion, etc.), shown as fluid compartment 322, configured to store the cooling fluid and a second compartment (e.g., a second section, an air cavity portion, etc.), shown as air compartment 324, configured to receive air. As air is added to the air compartment 324, the fluid membrane 320 pushes against the cooling fluid in the fluid compartment 322 and forces the cooling fluid through the outlet port 314 and into the outlet hose assembly 330. As shown in FIG. 12, when the air in the air compartment 324 has a first air volume (e.g., when the fluid reservoir 310 is in a filled state, etc.), the cooling fluid in the fluid compartment 322 may have a first fluid volume. As shown in FIG. 13, when the air in the air compartment 324 has a second air volume that is greater than the first air volume (e.g., when the fluid reservoir 310 is in an intermediate state, etc.), the cooling fluid in the fluid compartment 322 may have a second fluid volume that is less than the first fluid volume. As shown in FIG. 14, when the air in the air compartment has a third air volume that is greater than the second air volume (e.g., when the fluid reservoir 310 is in an emptied state, etc.), the cooling fluid in the fluid compartment 322 may have a third fluid volume that is less than the second fluid volume. In other embodiments, the fluid reservoir system 300 does not include the fluid membrane 320. For example, the cooling fluid and the air in the reservoir cavity 312 may not be separated and may contact each other at a surface of the cooling fluid.

[0067] As shown in FIGS. 12-15, the outlet hose assembly 330 includes a first hose (e.g., tube, conduit, etc.), shown as outlet hose 332, coupled to the fluid reservoir 310 and configured to receive the cooling fluid from the reservoir cavity 312, a nozzle (e.g., a head, etc.), shown as outlet nozzle 334, coupled to a distal end of the outlet hose 332 and configured to receive the cooling fluid from the outlet hose 332, and a check valve, shown as outlet check valve 336, configured to allow for the cooling fluid to flow through the outlet hose 332 away from the reservoir cavity 312 and prevent the cooling fluid fromAtty. Dkt. No.: 141240-0104 flowing through the outlet hose 332 toward the reservoir cavity 312. The outlet hose 332 is configured to align with the outlet port 314 to fluidly couple with the reservoir cavity 312 to receive the cooling fluid from the reservoir cavity 312. According to the exemplary embodiment shown in FIG. 15, the outlet nozzle 334 is configured to selectively engage the inlet valve 262 of the cooling cap 210. When the outlet nozzle 334 engages the inlet valve 262, the outlet nozzle 334 is fluidly coupled with the inlet valve 262 such that the fluid reservoir system 300 can provide the cooling fluid to the head cooling system 200 through the outlet nozzle 334 and into the inlet valve 262. In other embodiments, the outlet nozzle 334 is configured to provide the cooling to the outer surface of the outer layer 230 such that the fluid reservoir system 300 can provide the cooling fluid to the head cooling system 200 through the outlet nozzle 334 and onto the outer surface of the outer layer 230. In some embodiments, the outlet hose assembly 330 includes (a) a plurality of the outlet hoses 332 coupled to the fluid reservoir 310 and configured to receive the cooling fluid from the reservoir cavity 312 and (b) a plurality of the outlet nozzles 334 each coupled to a distal end of one of the outlet hoses 332 and configured to receive the cooling fluid from the outlet hoses 332. Each of the outlet nozzles 334 may provide the cooling fluid to a different cooling system of the personal cooling system 100. By way of example, a first of the outlet nozzles 334 may provide the cooling fluid to the head cooling system 200 and a second of the outlet nozzles 334 may provide the cooling fluid to the body cooling system 400.

[0068] In some embodiments, the outlet hose assembly 330 includes a second hose (e.g., inlet hose, etc.) coupled to the fluid reservoir 310 and configured to provide the cooling fluid from the head cooling system 200 to the reservoir cavity 312. By way of example, the outlet hose assembly 330 may include the second hose when the cooling fluid is recirculated between the head cooling system 200 and the fluid reservoir system 300 (e.g., when the inner layer 220 and the outer layer 230 are formed of a fluid impermeable material, etc.). In some embodiments, the second hose is coupled to the outlet nozzle 334 such that the head cooling system 200 can provide the cooling fluid to the fluid reservoir system 300 through the outlet nozzle 334 and the second hose. In other embodiments, the outlet hose assembly 330 includes a second nozzle coupled to the second hose. The second nozzle may selectively align with an outlet valve of the head cooling system 200 such that the head cooling system 200 can provide the cooling fluid to the fluid reservoir system 300 through the outlet valve of the head cooling system 200, the second nozzle, and the second hose. In some embodiments, the outlet hose assembly 330 includes a second check valve configuredAtty. Dkt. No.: 141240-0104 to allow for the cooling fluid to flow through the second hose toward the reservoir cavity 312 and prevent the cooling fluid from flowing through the second hose away from the reservoir cavity 312. In some embodiments, the head cooling system 200 and / or the fluid reservoir system 300 include a pump to actively recirculate the cooling fluid between the head cooling system 200 and the fluid reservoir system 300. In other embodiments, the cooling fluid is passively recirculated between the head cooling system 200 and the fluid reservoir system 300 (e.g., due to gravity, due to temperature differences between portions of the cooling fluid in the head cooling system 200 and the fluid reservoir system 300, etc.).

[0069] As shown in FIG. 15, when the outlet nozzle 334 engages the inlet valve 262, the outlet nozzle 334 is received by the inlet valve 262 to fluidly couple the outlet hose assembly 330 to the head cooling system 200. When the outlet nozzle 334 engages the inlet valve 262, the retention bar 264 is positioned behind the outlet nozzle 334 to prevent the outlet nozzle 334 from moving rearwards away from the inlet valve 262 and disengaging from the inlet valve 262. As shown in FIG. 15, the strap interface 266 may additionally or alternatively be coupled to the outlet hose 332 when the outlet nozzle 334 engages the inlet valve 262 to prevent the outlet nozzle 334 from disengaging from the inlet valve 262. By way of example, the strap of the strap interface 266 may be at least partially wrapped around the outlet hose 332 when the outlet nozzle 334 is engaged with the inlet valve 262 to couple the strap interface 266 with the outlet hose 332. In other embodiments, the retention bar 264 and / or the strap interface 266 may prevent the movement of the outlet nozzle 334 relative to the outer layer 230. For example, when the outlet nozzle 334 is providing the cooling fluid from the fluid reservoir system 300 to the outer surface of the outer layer 230, the retention bar 264 may be positioned behind the outlet nozzle 334 to prevent the outlet nozzle 334 from moving rearwards relative to the outer layer 230. As another example, when the outlet nozzle 334 is providing the cooling fluid from the fluid reservoir system 300 to the outer surface of the outer layer 230, the strap interface 266 may be coupled to the outlet hose 332 to prevent movement of the outlet nozzle 334 relative to the outer layer 230.

[0070] As shown in FIGS. 1 and 12-14, the fluid reservoir system 300 includes a compressor, shown as air compressor 340, coupled to the fluid reservoir 310. The air compressor 340 is configured to inject air into the air compartment 324 to increase a pressure inside of the air compartment 324. As the pressure in the air compartment 324 increases, the pressure applied on the cooling fluid contained in the fluid compartment 322Atty. Dkt. No.: 141240-0104 via the fluid membrane 320 increases and the cooling fluid is forced out of the fluid compartment 322 via the outlet hose assembly 330. In some embodiments, the air compressor 340 is a manual air compressor.

In other embodiments, the air compressor 340 is an electric air compressor that is powered by electricity to inject the air into the air compartment 324. By way of example, the air compressor 340 may be an electric blower configured to blow air from outside of the reservoir cavity 312 into the air compartment 324 to increase the pressure of the air inside of the air compartment 324. In still other embodiments, the fluid reservoir system 300 does not include the air compressor 340.

The fluid pump 350 is configured to pump the cooling fluid out of the fluid compartment 322 and into the fluid reservoir system 300. In some embodiments, the fluid pump 350 is a manual pump. By way of example, the fluid pump 350 may be a hand pump (e.g., a bulb pump, etc.) that can be actuated by a user of the fluid reservoir system 300 to pump the cooling fluid from the fluid compartment 322 and into the outlet hose assembly 330. In other embodiments, the fluid pump 350 is an electric pump that is powered by electricity to pump the cooling fluid from the fluid compartment 322 into the outlet hose assembly 330. By way of example, the fluid pump 350 may be an electric turbine pump that uses electricity to spin a turbine to pump the cooling fluid from the fluid compartment 322 into the outlet hose assembly 330. In still other embodiments, the fluid reservoir system 300 does not include the fluid pump 350. In some embodiments, the fluid reservoir system includes the fluid pump 350 and does not include the air compressor 340. In some embodiments, the fluid reservoir system does not include the fluid pump 350 and includes the air compressor 340.

[0072] According to the exemplary embodiment shown in FIGS. 16 and 17, the fluid pump 350 includes a first plurality of conduits (e.g., first hoses, etc.), shown as intake conduits 352, configured to receive the cooling fluid from the fluid reservoir 310; a first body, shown as intake grip 354, coupled to the intake conduits 352 and extending perpendicular relative to the intake conduits 352; a second plurality of conduits (e.g., second hoses, etc.), shown as outlet conduits 356, fluidly coupled to the intake conduits 352 and at least partially received within the intake conduits 352; a second body, shown as outlet gripAtty.

The intake conduits 352 are each coupled to a first portion of the outlet hose 332 (e.g., an upstream portion of the outlet hose 332 and are configured to receive the cooling fluid from the fluid reservoir 310 from the first portion of the outlet hose 332. The outlet conduits 356 are each coupled to a second portion of the outlet hose 332 (e.g., a downstream portion of the outlet hose 332 and are configured to provide the cooling fluid to the outlet nozzle 334 through the second portion of the outlet hose 332. In some embodiments, a first of the outlet conduits 356 is fluidly coupled to a first of the outlet nozzles 334 and a second of the outlet conduits 356 is fluidly coupled to a second of the outlet nozzle 334.

When a user of the fluid reservoir system 300 squeezes the intake grip 354 and the outlet grip 358 to move the outlet grip 358 toward the intake grip 354, the cooling fluid within the intake conduits 352 flows through the pump valves 360 into the outlet conduits 356 to force the cooling fluid towards the outlet nozzle 334. When the outlet grip 358 moves away from the intake grip 354, the pump valves 360 prevent the cooling fluid from flowing backward from the outlet conduits 356 into the intake conduits 352. In some embodiments, when the user of the fluid reservoir system 300 releases the outlet grip 358 and / or the intake grip 354, the outlet grip 358 and the intake grip 354 move away from each other (e.g., spring biased) and draw fluid from the fluid reservoir 310 into the intake conduits 352 so that the process can be repeated.
