     BACKGROUND 
     A barrier is an object that prohibits or impedes the progress of another object. Acoustic barriers prevent sound from traveling through them. A flood barrier stops water from flowing past it. A radiation barrier, such as a lead blanket used at the dentist&#39;s office, prevents harmful x-rays from damaging your body. 
     One common problem with barriers is that they are often large and hard to transport. As such, there is a need for barriers that can be stored small and quickly expanded (e.g., deployed) to cover a large area. Current solutions to this problem include folding barriers, barriers that roll up, and modular panel barriers. While these barriers solve the problem of size, they also introduce other challenges, such as increased degrees of freedom, slow expansion, manual assembly, and possible cuts, holes, and gaps in the barrier. 
     Despite the availability of a number of different barriers, manufacturers and users of barriers continue to seek new and improved barriers. 
     SUMMARY

     DETAILED DESCRIPTION 
     Embodiments disclosed herein are directed to barriers inspired by thick origami, methods of making such barriers, and methods of using such barriers. In an embodiment, the barrier can be switchable between an at least partially collapsed state and at least partially expanded state (e.g., a deployed state). For example, the barrier can be formed from a continuous sheet and a plurality of rigid sections (e.g., rigid panels) attached to or incorporated into the continuous sheet. The barrier can also include a plurality of hinges, such as hinge lines, between the panels that are formed from the continuous sheet. The hinges allow the barrier to be rigid foldable (e.g., the hinges can fold and unfold while the rigid sections remain stiff and rigid) between the expanded and collapsed states. 
     The continuous sheet (e.g., an unbroken surface of the barriers) can be split into portions thereof that are proximate to or include the rigid sections, and into other portions (e.g., the gaps between rigid sections) that form the hinges. The barrier is foldable along the hinges to switch between its expanded state to a smaller collapsed state. The barrier can include at least one vertex where multiple hinges converge together. The rigid sections and the hinges can create a tessellated mechanism that can, but is not limited to, one or more of dictating the degrees of freedom, control the folding and unfolding process, store energy to help expand or collapse the barrier, or maintain the barrier in certain states. 
     In a typical use of the barrier, the barrier can be stored and transported in its collapsed state. The barrier can include wheels, straps, and/or handles that are configured to facilitate transportation. For example, the barrier can be carried or towed like luggage or worn on the back like a backpack. When an operator of the barrier reaches a desired destination, the operator can place the barrier on a support surface (e.g., ground or floor) and expand (e.g., deploy) the barrier. In an embodiment, the barrier can be expanded automatically using one or more of compressed air, springs, telescoping poles, or braces. In another embodiment, the barrier can be expanded manually. The expansion of the barrier can be limited by the telescoping poles, the braces, a rope or some other fabric that reaches a maximum length, thus stopping the expansion of the barrier. Once the barrier is at its desired expanded state, the barrier can be locked in place using braces (e.g., locking hinges, over-center latches, or telescoping poles), or springs, or the barrier can maintain its shape because of friction in the hinges or from the friction between barrier and the support surface. 
     In an embodiment, the barrier can exhibit a generally “C” shape that provides front and flank protection when expanded that makes the barrier self-standing, but other configurations or support methods can be used. The barrier can have multiple configurations making it more versatile. For example, if the barrier needs to be set-up in a hallway, the sides can be folded in or, if the user wanted to use it to cover a wall, the barrier can be made completely flat and propped or attached to the wall. Once the barrier is no longer needed, the barrier can be folded back to its collapsed state which exhibits a compact size relative to the barrier in the expanded state. The barrier can be held in its collapsed state by straps, magnets, clasps, bag, or other suitable device. 
       FIG.  1 A  is a front view of a barrier  100  in an at least partially expanded state, according to an embodiment. The barrier  100  includes a continuous sheet  102  that includes at least two exterior surfaces  104 . The barrier  100  can also include a plurality of rigid sections  106  that are attached to at least one of the exterior surfaces  104  of the continuous sheet  102  (as shown), disposed in the continuous sheet  102  (see  FIG.  4 D- 4 E ), or otherwise incorporated into the continuous sheet  102 . The rigid sections  106  can define gaps therebetween. The portion of the continuous sheet  102  that is adjacent to the gaps can form hinges  108  that are configured to fold and unfold, such as fold and unfold without creasing. Allowing the hinges  108  to fold and unfold can switch the barrier  100  between the expanded state ( FIG.  1 A ) and the collapsed state ( FIG.  1 C ). In an embodiment, the barrier  100  can optionally include a plurality of springs  110  that ensure correct deployment of the barrier  100  and are configured to maintain the barrier  100  in the expanded state. 
     As shown in  FIG.  1 A , the barrier  100  exhibits a relatively large exposed area when the barrier  100  is in the expanded state. For example, the barrier  100  can cover an area that is about 2 feet to about 10 feet by about 2 feet to about 10 feet, such as an area that is about 4 feet by about 6 feet. For instance, the barrier  100  can exhibit a length L 1  of about 3.5 feet and a perimeter of about 5.5 feet when in the expanded state. In some embodiments, the barrier  100  is self-standing. In another example, the barrier  100  can exhibit a weight that is less than about 120 lbs., such as less than about 100 lbs., less than about 90 lbs., less than about 75 lbs., less than about 60 lbs., or less than about 50 lbs. Additionally, the barrier  100  can be configured to switch from the collapsed state to the expanded state in less than about 20 seconds by a single individual, such as in less than about 15 seconds, or less than about 10 seconds. In other words, the barrier  100  can be expanded easily and quickly. 
     In an embodiment, the continuous sheet  102  of the barrier  100  can be made from a single sheet that may be uncut. Forming the continuous sheet  102  from a single uncut sheet can allow the barrier  100  to exhibit the folding characteristics of origami and prevents holes in the barrier  100  through which items and energy can pass. As previously discussed, portions of the continuous sheet  102  that are between the rigid sections  106  can form the hinges  108  of the barrier  100 , thereby allowing the barrier  100  to be foldable (e.g., switch between the expanded and collapsed state) without creasing. The barrier  100 , including the continuous sheet  102 , can exhibit improved barrier properties than a substantially similar barrier that includes a discontinuous sheet. For example, forming the continuous sheet  102  from bulletproof material can create bulletproof hinges, can avoid the uncertain ballistic behavior of traditional hinges, and can ensure that the ballistic rating would be at the least rated to the ballistic level of the continuous sheet  102 . In another example, forming the continuous sheet  102  from acoustic absorbing material can substantially prevent acoustic energy from passing through the hinges  108 . 
     The continuous sheet  102  can be formed of any suitable compliant material. For example, the continuous sheet  102  can include a material that exhibits excellent ballistic properties, acoustic absorbing properties, a good yield or shear strength, good abrasion resistance, good resistance to sunlight (e.g., ultra-violet light resistance), good water resistance (e.g., waterproof), etc. In another example, the continuous sheet  102  can include a material that resists creasing. In another example, the continuous sheet  102  can include one or more of ballistic nylon, Kevlar®, ultra-high-molecular-weight polyethylene fabric, or another suitable material. 
     In an embodiment, the continuous sheet  102  can be formed from a plurality of layers (as shown in  FIGS.  4 B- 4 E ), such as a plurality of layers of ballistic fabric. At least one (e.g., each) of the plurality of layers can be a continuous layer. In an example, the barrier  100  can be formed from 2 layers to 5 layers, 4 layers to 7 layers, 5 layers to 10 layers, 7 layers to 15 layers, 10 layers to 20 layers, 15 layers to 25 layers, 20 layers to 40 layers, 30 layers to 50 layers, or more than 50 layers. In an example, the continuous sheet  102  can be formed from a plurality of layers that are substantially the same. In another example, the continuous sheet  102  can be formed from a plurality of different layers. In such an example, the layers that are different can exhibit at least one of a material composition, porosity, structure (e.g., a fibrous structure vs. non-porous film structure), or thickness that is different. It is noted that the continuous sheet  102  can be formed from a plurality of layers regardless of the material used to form the continuous sheet  102 . 
     In an embodiment, the continuous sheet  102  can exhibit a thickness that is negligible (e.g., greater than 0 mm to about 0.75 mm, greater than about 0 to about 1.5 mm) or non-negligible (e.g., greater than about 0.75 mm or greater than about 1.5 mm). For example, the continuous sheet  102  can exhibit a thickness that is less than about 25 mm, greater than 0 mm to about 12.5 mm, about 2.5 mm to about 6 mm, about 5 mm to about 13 mm, about 6 mm to about 19 mm, greater than about 13 mm, or about 13 mm to about 25 mm. Increasing the thickness of the continuous sheet  102  can improve the barrier properties of the barrier  100 . For example, increasing the thickness of the continuous sheet  102  can increase the ballistic properties, increase acoustic barrier properties, increase fluid barrier properties (e.g., decrease a water permeation rate), decrease a heat permeation rate, increase opaqueness, increase impact resistance, etc. of the barrier  100 . However, increasing the thickness of the continuous sheet  102  can increase the weight of the barrier  100  thereby making it harder to transport and operate. Additionally, as will be discussed in more detail with regards to  FIGS.  3 A- 3 C , increasing the thickness of the continuous sheet  102  can increase the complexity of the hinges  108 . 
     The configuration of the hinges  108  can depend on the number of layers used to form the continuous sheet  102  and/or the thickness of the continuous sheet  102 . For example, increasing number of layers and/or thickness of the continuous sheet  102  can increase the distance between the rigid panels  106 , require the use of thick membrane folds (e.g., shown in  FIGS.  3 A- 3 C ), etc. 
     In an embodiment (not shown), the barrier  100  can be formed form a discontinuous sheet. In such an embodiment, the hinges  108  can be formed using traditional hinges, such as a butt hinge, a T-hinge, a strap hinge, etc. The traditional hinges can be strengthened or covered by the continuous sheet  102  or another sheet, thereby preventing projectiles, energy, or other material from passing through the hinge area. 
     The rigid sections  106  perform several functions for the barrier  100 . For example, the rigid sections  106  can be configured to resist deformation (e.g., resist folding and unfolding). The ability of the rigid sections  106  to resist deformation can facilitate controllably switching the barrier  100  between the collapsed and expanded states since the movement of the barrier  100  is restricted (e.g., prevents the formation of new hinges). Additionally, the ability of the rigid section  106  to resist deformation can make it easier to maintain the barrier  100  in the expanded state. In another example, the rigid sections  106  can improve the ballistic properties, acoustic barrier properties, etc. of the barrier  100  compared to a substantially similar barrier that does not include the rigid sections  106 . 
     In an embodiment, the rigid sections  106  can include rigid panels (e.g., rigid material) that are distinct from the continuous sheet  102 . As shown in  FIG.  1 A , the rigid panels can be attached to at least one of the exterior surfaces  104  of the continuous sheet  102 . The rigid panels can be made from any rigid material, such as a material with ballistic properties or a light weight material. For example, the rigid panels can be formed from a light weight composite of aluminum and polyethylene (e.g., Dibond®), a fiberglass composite (e.g., Garolite), carbon fiber, magnesium alloys, aluminum alloys, silicon carbide, aluminum oxide, steel, titanium, ultra-high molecular weight polyethylene, synthetic spider silk, metal composite foams, other suitable ceramics, other suitable polymers, other suitable composites, or combinations thereof. For example, if the barrier  100  is a ballistic barrier, the panels can be formed from Garolite or carbon fiber because these materials are light weight, bullet-resistant, rigid, and inexpensive. 
     The rigid panels of the rigid sections  106  can be attached to the continuous sheet  102  using any suitable method. For example, the panels of the rigid sections  106  can be attached to the continuous sheet  102  by sewing, gluing, melting, bolting, pocketing, or any combination thereof. Such methods of attachment can minimize shearing between the layers of the continuous sheet  102  and the rigid panels, prevent bending of the rigid panels, and may not introduce weak points in the barrier  100 . For example, a sharpened bolt can split a weave of the continuous sheet  102  fairly easily and attach the rigid panels snugly to the continuous sheet  102 . However, using bolts to attach the rigid panels to the continuous sheet  102  can damage the continuous sheet  102 . 
     In an embodiment, the rigid sections  106  can include rigid panels disposed in the continuous sheet  102 . For example, the panels can be placed in the middle of the continuous sheet  102 . For instance, the continuous sheet  102  can be formed from a plurality of layers and the panel can be placed between two of the layers. The rigid panels that are disposed in the continuous sheet  102  can include any of the rigid panels disclosed herein. The rigid panels can be maintained in a selected portion of the continuous sheet  102  using any suitable method, such as by sewing, gluing, melting, bolting, pocketing, or any combination thereof. 
     In an embodiment, the rigid sections  106  can include portions of the continuous sheet  102  that are reinforced to form the rigid sections  106 . For instance, reinforcing the continuous sheet  102  can cause the continuous sheet  102  to resist folding. In an example, the continuous sheet  102  can be reinforced by attaching or disposing any of the rigid panels disclosed herein to or in the continuous sheet  102 . In another example, the continuous sheet  102  can be reinforced by laminating at least one thermoplastic to the continuous sheet  102 . In another example, the continuous sheet  102  can be reinforced by impregnating the continuous sheet  102  with an epoxy, resin, or other hardener (collectively referred to as “hardener”). In such an example, the rigid sections  106  can be formed by using the continuous sheet  102  as the matrix and then adding the hardener to harden selected regions of the continuous sheet  102 . Heat and pressure can be applied to the continuous sheet  102  and the hardener to facilitate hardening of the hardener. A mask (e.g., rubber that would remain attached to the barrier  100 ) can be used to selectively cure the hardener. In another example, the continuous sheet  102  can be reinforced by sewing a plurality of stiches in the continuous sheet  102 . The stiches can limit movement between the plurality of layers of the continuous sheet  102  thereby forming the rigid sections  106 . These methods of creating the rigid sections  106  are not mutually exclusive and can be combined. 
     In an embodiment, the rigid sections  106  (e.g., rigid panels) can exhibit a thickness that is greater than about 0.8 mm, such as in ranges of about 0.8 mm to about 25 mm, about 0.8 mm to about 3 mm, about 1.6 mm to about 6.4 mm, about 1.6 mm to about 13 mm, or about 9.5 mm to about 25 mm. It is noted that the thickness of the rigid sections  106  can depend on the material or method used to form the rigid sections  106 . As such, in some embodiments, the thickness of the rigid section  106  can be less than about 0.8 mm or greater than 25 mm. In an embodiment, the rigid sections  106  can include a surface that is flat, exhibits a non-flat shape (e.g., a concave or convex shape), includes one or more protrusion extending therefrom, or includes one or more recesses extending inwardly therefrom. 
     In an embodiment, the rigid sections  106  can be configured to limit the degrees of freedom of the barrier  100 . For example, the rigid sections  106  can be configured to limit the barrier  100  to a single degree of freedom. Additionally, the thickness of the rigid sections  106  can be used to create interference. For example, the thickness of the rigid sections  106  can be equivalent of placing hinges on certain sides of the thick material so as to have the thickness interfere or restrict the movement of the hinges (e.g., most doors only swing one direction because hinges are placed on the valley side of the door and the thickness of the door and door frame prevent the door from swinging the other direction). As such, the thickness of the rigid sections  106  can limit degrees of freedom and can determine the available configurations of the barrier  100 , thereby allowing more rapid set up and take down of the barrier  100 . 
     In an embodiment, the rigid sections  106  can be made to at least partially overlap the hinges  108  to prevent the hinges  108  from being a weak point of the barrier  100 . In an embodiment, the rigid sections  106  can include multiple layers of rigid panels  106  (e.g., rigid panels  106 ) on one or both sides of the continuous sheet  102 . 
     Each of the hinges  108  includes a mountain side  112  that forms a generally convex shape and a valley side  114  that opposes the mountain side  112 . Each of the hinges  108  can also form hinge lines that intersect with each other at least one vertex  116 . As will be discussed in more detail below, the mountain side  112  of the hinges  108 , the valley side  114  of the hinges  108 , and how the hinges  108  intersect at the vertex  116  can be configured to bias the hinges  108  to bend in certain directions and to improve the stability of the barrier  100  when the barrier  100  is in the expanded configuration. 
     In an embodiment, the barrier  100  can include a plurality of springs  110  that are coupled to one or more components of the barrier  100 . For example, at least some of the springs  110  can be coupled to the rigid sections  106  of the barrier  100  and can span across the hinges  108 . In another embodiment, the barrier  100  does not include the springs  110 . 
     The springs  110  can be configured to make the barrier  100  stable when the barrier  100  is in the expanded state and to provide spring-assisted actuation (e.g., easier switching between the expanded and collapsed states). For example, the springs  110  can apply a force across the hinges  108  that is configured to cause the hinges  108  to unfold. Such springs  110  can support at least a portion of the mass of the barrier  100 . For instance, springs  110  that support at least a portion of the mass of the barrier  100  can automatically cause the barrier  100  to switch from the collapsed state to the expanded state or reduce the force required to manually switch the barrier  100  from the collapsed state to the expanded state. In another instance, the springs  110  can support enough of the mass of the barrier  100  that the barrier  100  remains in the expanded state. In another example, the springs  110  can be configured to prevent the barrier  100  from folding in the wrong direction. For instance, the springs  110  can bias the hinges  108  to fold in a selected directions. 
     In some embodiments, the springs  110  can be compression springs, leaf springs, torsional springs, resilient material (e.g., an elastomer), other suitable biasing elements, or any combination thereof. For example, the springs  110  can include steel springs. Alternatively or additionally, the springs  110  can be replaced with air cylinders, solenoids, motors, shape memory alloy actuators, other suitable actuators, or combinations thereof. 
       FIG.  1 B  is a top view of the barrier  100  shown in  FIG.  1 A  while the barrier  100  is in the at least partially expanded state, according to an embodiment. As shown in  FIG.  1 B , the barrier  100  can include at least one brace  118 . The brace  118  can be configured to keep the barrier  100  in the expanded state when the brace  118  is activated (e.g., when the brace  118  is extended). For example, the brace  118  can add at least one compressive member to the barrier  100  for support. 
     In an embodiment, the brace  118  can include at least one telescoping pole that holds the barrier  100  in its expanded state. The telescoping poles can prevent gravity from pulling the barrier  100  into its collapsed state. For instance, the telescoping poles can expand from 25 in. to 36 in., allowing sufficient internal overlap to prevent bending and releasing, thereby allowing the barrier  100  to remain expanded. In another example, the barrier  100  can include air cylinders, solenoids, motors, shape memory alloys, light or temperature sensitive materials, leaf spring, other suitable braces, or combinations thereof instead of or in conjunction with the brace  118 . 
     The barrier  100  is configured to be self-standing when the barrier  100  is in the expanded state. The barrier  100  can exhibit any shape that allows that barrier  100  to be self-standing. For example, the barrier  100  can exhibit a shape that includes at least one flat surface supported by at least one beam or another flat surface that extends from the flat surface towards a support surface. In such an example, the barrier  100  can form an A-frame. In another example, the barrier  100  can exhibit a shape that includes at least two flat surfaces that extend at an angle relative to each other, such as a generally V-shape, generally L-shape, or a generally W-shape. In another example, as shown in  FIG.  1 C , the barrier  100  can exhibit a curved shape, such as a generally C-shape, a generally O-shape, or a generally J-shape. In another example, the barrier  100  can exhibit a shape that offers protection from multiple angles (e.g., from a front and flank direction), such as a generally V-shape or a generally C-shape. 
     In an embodiment, the barrier  100  can include one or more additional components (not shown) that facilitate the operation of the barrier  100 . For example, the barrier  100  can have lights attached to a front of the barrier  100 . In another example, the barrier  100  can also have supports attached to the sides or top thereof upon which a gun can rest. In another example, the barrier  100  can have a clear section or define a gap so a user can see through it. In another example, the barrier  100  can have handholds, straps, wheels, or another device that facilitates movement of the barrier  100 . In another example, the barrier  100  can include pockets, such as pockets sewn into the continuous sheet  102  and or formed in the rigid sections  106 . 
     The barrier  100  may be unwieldy and hard to store when the barrier  100  is in the expanded state. As such, the barrier  100  is switchable between the expanded state and an at least partially collapsed state.  FIG.  1 C  is an isometric view of the barrier  100  of  FIGS.  1 A- 1 B  in the at least partially collapsed configuration, according to an embodiment. As shown in  FIG.  1 C , the barrier  100  exhibits a relatively more compact size when the barrier  100  is in the collapsed state than when the barrier  100  in the expanded state. The relatively more compact size of the barrier  100  when the barrier  100  is in the collapsed state can facilitate storage and transportation of the barrier  100 . For example, the barrier  100  can exhibit a size and shape that allows the barrier  100  to be stored in a trunk of a car when the barrier  100  is in the collapsed state. In another example, the barrier  100  can exhibit a size and shape that allows the barrier  100  to be carried like a backpack or a suitcase when the barrier  100  is in the collapsed state. 
     Switching the barrier  100  from the expanded state to the collapsed state can include decreasing at least one of a length, width, or thickness of the barrier  100 . Similarly, switching the barrier  100  from the collapsed state to the expanded state can include increasing at least one of the length, width, or thickness of the barrier  100 . For example, referring to  FIGS.  1 A- 1 B , the barrier  100  exhibits a first length L 1 , a first width W 1 , and a first thickness t 1  when the barrier  100  is in the expanded state. Meanwhile, referring to  FIG.  1 C , the barrier  100  exhibits a second length L 2 , a second width W 2 , and a second thickness t 2  when the barrier  100  is in the collapsed state, wherein at least one of the second length L 2 , the second width W 2 , or the second thickness t 2  is less than at least one of the first length L 1 , the first width W 1 , or the first thickness t 1 , respectively. 
     In an embodiment, switching the barrier  100  from the expanded state to the collapsed state can include decreasing the volume occupied by the barrier  100 . For example, the volume of the barrier  100  in the expanded state can be defined by a box having dimensions equal to the first length L 1 , the first width W 1 , and the first thickness t 1 . Similarly, the volume of the barrier  100  in the collapsed state can be defined by a box having dimensions equal to the second length L 2 , the second width W 2 , and the second thickness t 2 . In such an example, the volume of the barrier  100  in the collapsed state is less than the volume of the barrier  100  in the expanded state. In another embodiment, switching the barrier  100  from the expanded state to the collapsed state can include increasing the volume occupied by the barrier  100 . For example, the barrier  100  can form a substantially planar shape when the barrier  100  is in the expanded state which can cause the barrier  100  in the expanded state to occupy a smaller volume than the barrier  100  in the collapsed state. 
     The barriers disclosed herein can exhibit a number of different origami patterns that can create a barrier that is at least one of thick-foldable, can fold up compactly, and can be expanded into a large barrier (e.g., a curved barrier). For example, the barrier  100  shown in  FIGS.  1 A- 1 C  exhibits a 6-story modified Yoshimura pattern.  FIGS.  2 A- 2 D  are plan views of barriers  200   a - d  that are in a planar configuration (e.g., are fully expanded) and that exhibit different Yoshimura or modified Yoshimura patterns, according to different embodiments. Except as otherwise disclosed herein, the barriers  200   a - d  are the same as or substantially similar to the barrier  100  of  FIGS.  1 A- 1 C . For example, each of the barriers  200   a - d  includes a continuous sheet  202 , a plurality of rigid sections  206 , and a plurality of hinges  208 . Additionally, each of the barriers  200   a - d  are configured to switch between an at least partially expanded state to an at least partially collapsed configuration. 
       FIG.  2 A  illustrates a barrier  200   a  that exhibits a Yoshimura pattern that is composed of degree-6 vertices, according to an embodiment.  FIGS.  2 B- 2 D  illustrate barriers  200   b - d  that each exhibit a modified Yoshimura pattern, according to an embodiment. Barriers  200   b - d  exhibit a modified Yoshimura pattern because each degree-6 vertex of a conventional Yoshimura pattern is split into two degree-4 vertices. The modified Yoshimura patterns shown in  FIGS.  2 B- 2 D  are also known as a version of the Huffman pattern and/or a version of an origami pattern used by magicians known as the Troublewit. It is noted that, in an embodiment, the barrier  200   a  can exhibit a modified Yoshimura pattern and/or the barriers  200   b - d  can exhibit a Yoshimura pattern. 
       FIGS.  2 A- 2 D  illustrate that the barriers  200   a - d  that exhibit a Yoshimura or a modified Yoshimura pattern can include a number of stories. “Stories” are defined as the number of rigid sections  206  in the vertical direction of the barriers  200   a - d . Each of the stories of the barriers  200   a - d  can include a generally horizontal hinges  208  that separates each of the stories. For example,  FIG.  2 A  illustrates that the barrier  200   a  includes three stores  220   a ,  FIG.  2 B  illustrates that the barrier  200   b  includes four stories  220   a ,  FIG.  2 C  illustrates that the barrier  200   c  includes five stories  220   c , and  FIG.  2 D  illustrates that the barrier  200   d  includes six stories  220   d . While it is possible to have a Yoshimura or a modified Yoshimura pattern having an infinite amount of stories, for practical reasons, such as manufacturing, it is advantageous to limit the Yoshimura or a modified Yoshimura patterns to 3 to 10 stories, and more particularly, to 3 to 6 stories. 
     The number of stories of the Yoshimura or a modified Yoshimura pattern used to form the barriers  200   a - d  can also affect the stability of the barriers  200   a - d  when expanded for several reasons. First, increasing the number of stories of the barriers  200   a - d  can increase the stability of the barriers  200   a - d  because it can increase the width of the barriers  200   a - d . For example, the wider footprint of the 6-story barrier  202   d  provides better resistance to tipping than the 5-story barrier  202   c , the 4-story barrier  202   b , and the 3-story barrier  202   a . Second, the structural stability of the barriers  200   a - d  can also be increased by increasing the number of stories of the barriers  200   a - d  because parallel axes of the hinges  208  become less collinear. For example, the angled hinges  208  on the 4-story barrier  202   b  are closer to being collinear than those on the 6-story barrier  202   d . The closer the hinges  208  are to being collinear, the more diagonal sheering can occur. Third, increasing the number of stories of the barriers  200   a - d  can result in more hinges  208 , which can decrease stability of the barriers  200   a - d . For example, increasing the number of stories above a certain number (e.g., greater than 8 stories, greater than 10 stories, greater than 15 stories, or greater than 20 stories) can decrease the stability of a barrier even though the barrier exhibits an increased width and non-collinear hinges. In view of the above, the inventors have found that the 6-story barrier  202   d  provides enough stories to have a stable base, and fewer collinear hinges  208 , and not too many hinges  208 . As such, it is currently believed by the inventors that the 6-story barrier  202   d  may result in a universal barrier that works the same in both directions and helps reduce set up time and eliminates set up error in critical situations. 
     The number of stories of the Yoshimura or a modified Yoshimura pattern that is used to form the barriers  200   a - d  can also determine the storage efficiency and storage size of the barriers  200   a - d  when the barriers  200   a - d  are in a collapsed state. In particular, increasing the number of stories of the Yoshimura or a modified Yoshimura pattern increases the unused space in the middle of the folded Yoshimura or a modified Yoshimura pattern and increases size and number of the gaps between the folded layers of the Yoshimura or a modified Yoshimura pattern. For example, the barrier  200   a  of  FIG.  2 A  exhibits better storage efficiency and storage size than the barriers  200   b - d  of  FIGS.  2 B- 2 D . However, increasing the number of stories of the Yoshimura or a modified Yoshimura pattern can decrease a collapsed base dimensions of the barriers  200   a - d  (e.g., the second width W 2  and the second thickness t 2  shown in  FIG.  1 C ) and increases a length of the barriers  200   a - d  (e.g., the second length L 2  shown in  FIG.  1 C ) when the barriers  200   a - d  are in a collapsed state. For example, the 6-story barrier  202   d  shown in  FIG.  2 D  has smaller collapsed base dimensions and larger storage height than the 4-story barrier  202   b  shown in  FIG.  2 B . 
       FIGS.  2 A- 2 D  illustrate that the rigid sections  206  can exhibit a shape that exhibits a long edge  222  and two angular edges  224  that extend from the long edge  222  at an oblique angle. For example, as shown in  FIG.  2 A , the rigid sections  206  can exhibit a generally triangular shape. In such an example, the two angular edges  224  intersect with each other. In another example, as shown in  FIGS.  2 B- 2 D , the rigid sections  206  can exhibit a generally trapezoidal shape. In such an example, the rigid sections  206  exhibit a short edge  226  that opposes the long edge  222  and the angular edges  224  extend between the long edge  222  and the short edge  226 . The short edge  226  can be substantially parallel to the long edge  222 . It is noted that rigid sections  206  exhibiting a generally trapezoidal shape can form hinges  208  that are less collinear than rigid sections  206  exhibiting a generally triangular shape. 
     Each of the barriers  200   a - d  includes two opposing surfaces  228  that are configured to contact a support surface (e.g., ground, floor, etc.) when the barriers  200   a - 200   d  are in the expanded state. The two opposing surfaces  228  can be defined by or positioned proximate to some of the long edges  222  of the rigid sections  206 . The two opposing surfaces  228  can also be defined by or positioned proximate to the intersection of the two angular edges  224  when the rigid sections  206  exhibit a generally triangular shape or by the short edge  226  when the rigid sections  206  exhibit a generally trapezoidal shape. Increasing the number of long edges  222  that form the opposing surface  228  that contacts the support surface increases the stability of the barriers  200   a - d  when the barriers  200   a - d  the expanded state. For example, an opposing surface  228  that is formed from two long edges  222  is more stable than an opposing surface  228  that is formed from a single long edge  222 . 
     The barriers  200   a - d  can have an odd number of stories or an even number of stories. However, a Yoshimura or a modified Yoshimura pattern that exhibits an even number of stories may exhibit improve the stability and facilitate quicker deployment than a Yoshimura or a modified Yoshimura pattern that exhibit an odd number of stories. For example, barriers  200   a  and  200   c  of  FIGS.  2 A and  2 C  exhibit an odd number of stories. Forming the barriers  200   a  and  200   c  from an odd number of stories can cause the two opposing surfaces  228  thereof to be defined by or proximate to a different number of long edges  222 , intersections of the angular edges  224 , or the short edges  226 . As such, one of the two opposing surfaces  228  of the barriers  200   a  and  200   c  can be more stable when contacting the support surface than the other of the two opposing surfaces  228 . Therefore, an operator of the barriers  200   a  and  200   c  may need to be aware of which opposing surface  228  contacts the support surface to maximize the stability of the barriers  200   a  and  200   c . Meanwhile, the barriers  200   b  and  200   d  of  FIGS.  2 B and  2 D  exhibit an even number of stories. Forming the barriers  200   b  and  200   d  from an even number of stories causes the two opposing surfaces  228  thereof to be defined by or proximate to the same number of long edges  222 , intersections of the angular edges  224 , or the short edges  226 . As such, both of the two opposing surfaces  228  of the barriers  200   b  and  200   d  are equally stable when contacting the support surface. Therefore, an operator of the barriers  200   b  and  200   d  does not need to check which of the two opposing surfaces  228  contacts the support surface thereby facilitating deployment of the barriers  200   b  and  200   d.    
     Forming the barriers  200   a - d  using the Yoshimura or a modified Yoshimura pattern causes the barriers  200   a - d  to only exhibit a single degree of freedom, which provides additional control while deploying the barriers  200   a - d . The additional control in deploying the barriers  200   a - d  can also decrease the time required to deploy the barriers  200   a - d . Additionally, forming the barriers  200   a - d  using the Yoshimura or a modified Yoshimura pattern can enable the rigid sections  206  of the barriers  200   a - d  to exhibit flat-edge geometry (e.g., the long or short edges  222 ,  226 ) which increases the stability of the barriers  200   a - d  compared to a barrier that does not include a flat-edge geometry. 
     While  FIGS.  2 A- 2 D  illustrate that the barriers  200   a - d  are formed using a Yoshimura or a modified Yoshimura pattern, it is noted that any of the barriers disclosed herein can also be formed using other origami patterns. For example, any of the barriers disclosed herein can exhibit a Miura-ori pattern. Barriers exhibiting a Miura-ori pattern can fold more compactly than barriers exhibiting a Yoshimura or a modified Yoshimura pattern. Barriers exhibiting a Miura-ori pattern may require the use of offsets or other features that account for the thickness of layers stacking inside of each other. In another example, any of the barriers disclosed herein can exhibit a square twist pattern which can have similar benefits as the Miura-ori pattern. In another example, any of the barriers disclosed herein can exhibit a diamond pattern. Barriers exhibiting a diamond pattern can exhibit semicircular shapes while in their intermediate states (e.g., a state between the collapsed and expanded states) and can fold more compactly than similar barriers exhibiting a Yoshimura or a modified Yoshimura pattern. Additionally, barriers that exhibit a diamond pattern can exhibit more than a single degree of freedom while switching the barriers between the expanded and collapsed states. 
     In an embodiment, any of the continuous sheets disclosed herein can be completely planar (e.g., exhibit no protrusions or intrusions). However, a continuous sheet that is completely planar can have problems folding and unfolding, especially when the continuous sheet exhibits a non-negligible thickness. For example, the completely planar continuous sheet can form a hinge having a mountain side and a valley side. Folding the completely planar continuous sheet can put portions of the completely planar continuous sheet that is at or near the mountain side of the hinge to be in tension and the portions of the completely planar continuous sheet that is at or near the valley side in compression. Causing portions of the completely planar continuous sheet to be in tension can cause the completely planar continuous sheet to tear. Additionally, compressing portions of the completely planar continuous sheet can cause the completely continuous sheet to crease which can weaken the continuous sheet. Additionally, causing portions of the completely planar sheet to be in tension and/or compression can make compactly folding the substantially planar continuous sheet difficult. 
     As such, in some embodiments, the barriers disclosed herein can include continuous sheets that are configured to reduce the tension and compression forces in the continuous sheets, especially if the continuous sheet exhibits a non-negligible thickness. In particular, the fold lines of the continuous sheet that act as hinges can be configured to accommodate the thickness of the continuous sheet. For example, the hinges can exhibit a thick membrane fold (e.g., turn-of-cloth fold).  FIGS.  3 A- 3 C  are partial cross-sectional views of a portion of a barrier  300  that includes a hinge  308  exhibiting a thick membrane fold when the hinge  308  is completely unfold, partially folded, and completely folded, respectively, according to embodiment. Except as otherwise disclosed herein, the barrier  300  can be the same as or similar to any of the barriers disclosed herein. For example, the barrier  300  can include a continuous sheet  302  that forms the hinge  308  and a plurality of rigid sections  306 . Additionally, the barrier  300 , and in particular the hinge  308 , can be used in any of the barrier embodiments disclosed herein. 
     To form the thick membrane fold, the continuous sheet  302  is formed from a plurality of layers, such as from at least a first layer  332  and a second layer  334  that opposes the first layer  332 . The first layer  332  defines the mountain side  312  of the hinge  308  and one of the two exterior surface  304  of the continuous sheet  302 . Similarly, the second layer  334  defines the valley side  314  of the hinge  308  and the other of the two exterior surfaces  304  of the continuous sheet  302 . The first layer  332  includes extra material at or near the mountain side  312  of the hinge  308  whereas the second layer  334  does not include extra material. In an example, the continuous sheet  302  also includes one or more additional layers between the first and second layers  332 ,  334 . In such an example, the one or more addition layers can also include extra material. However, the amount of extra material that each of the one or more additional layers have generally decreases from the first layer  332  to the second layer  334 . 
     Referring to  FIG.  3 A , the extra material of the first layer  332  and, optionally, the one or more additional layers bunches up when the hinge  308  is unfolded. The bunching up of the extra material can form a protrusion  336  on the mountain side  312  of the hinge  308 . Meanwhile, the second layer  334  is substantially planar. The presence of the protrusion  336  on the mountain side  312  and the substantially planar second layer  334  can bias the hinge  308  to fold in a certain direction.  FIGS.  3 B and  3 C  illustrate how the extra material of the first layer  332  and, optionally, the one or more additional layers allows the hinge  308  to be folded without causing the first layer  332  to be in tension and the second layer  334  to be compressed. As such, the extra material of the first layer  332  and, optionally, the one or more additional layers can be used to increase the flexibility of the hinge  308  and allowing the hinge  308  to be completely unfolded and completely folded regardless of the thickness or number of layers used to form the continuous sheet  302 . 
     In an embodiment, the continuous sheet  302  can be configured to contain the bunching at or near the mountain side  312  of the hinge  308  and cause the protrusion  336  to extend outwardly from the mountain side  312  of the hinge  308 . For example, the portions of the continuous sheet  302  adjacent to the hinges  308  can be sewn together to prevent the extra material from bunching at a location that is spaced from the hinge  308 . This can result in the hinges  308  being biased. This means that the protrusion  336  may remain visible when the barrier  300  is in the expanded state. 
     As previously discussed, the barriers disclosed herein can be formed from a continuous sheet that includes one or more layers and a plurality of rigid sections that are attached to, disposed in, and/or reinforces the continuous sheet.  FIGS.  4 A- 4 E  are partial cross-sectional views of barriers  400   a - e  that have different arrangements of one or more layers and a plurality of rigid sections, according to different embodiments. Except as otherwise disclosed herein, the barriers  400   a - e  are the same as or substantially similar to any of the barriers disclosed herein. Additionally, any of the barriers disclosed herein can have any of the arrangements illustrated in  FIGS.  4 A- 4 E . 
     Referring to  FIG.  4 A , the barrier  400   a  includes a continuous sheet  402   a  that includes two exterior surfaces  404   a  and a plurality of rigid sections  406   a . The plurality of rigid sections  406   a  are attached to at least one of the two exterior surfaces  404   a  of the continuous sheet  402   a . The continuous sheet  402   a  is formed from at least one layer  432   a . The at least one layer  432   a  can include a single layer or a plurality of layers that are each substantially the same. 
     Referring to  FIG.  4 B , the barrier  400   b  includes a continuous sheet  402   b  that includes two exterior surfaces  404   b  and a plurality of rigid sections  406   b  that are attached to at least one of the two exterior surfaces  404   b . The continuous sheet  402   b  is formed from at least at least one first layer  432   b  and at least one second layer  434   b  that is different than the first layer  432   b . For example, the first layer  432   b  can exhibit a material composition, structure, etc. that is different than the second layer  434   b.    
     Referring to  FIG.  4 C , the barrier  400   c  includes a continuous sheet  402   c  that includes two exterior surfaces  404   c  and a plurality of rigid sections  406   c  that are attached to at least one of the two exterior surfaces  404   c . The continuous sheet  402   c  is formed from at least at least one first layer  432   c , at least one second layer  434   c , and at least one third layer  438   c . The third layer  438   c  is different than the first and second layers  432   c ,  434   c  and, the first and second layers  432   c ,  434   c  are substantially the same or different than each other. In an embodiment, at least one of the first or second layers  432   c ,  434   c  can form protective layers that are configured to protect the third layer  438   c . For example, the barrier  400   c  can be a ballistic barrier and the third layer  438   c  can include Kevlar. However, Kevlar has a relatively low abrasion resistance, water resistance, and ultra-violet light resistance and, as such, exposing the third layer  438   c  to the environment can adversely affect the ballistic properties of the Kevlar. In such an example, the first and second layers  432   c ,  434   c  of the barrier  400   c  can be formed from a material that exhibits better abrasion resistance, water resistance, and/or ultra-violet light resistance than Kevlar, such a ballistic nylon. As such, the first and second layers  432   c ,  434   c  can protect the third layer  438   c  from the environment and maintain the ballistic properties of the third layer  438   c.    
     Referring to  FIG.  4 D , the barrier  400   d  includes a continuous sheet  402   d  and a plurality of rigid sections  406   d  that are disposed in the continuous sheet  402   d . For example, the continuous sheet  402   d  can include at least one first layer  432   d  and at least one second layer  434   d . The first and second layers  432   d ,  434   d  can be substantially the same or different (e.g., exhibit different material compositions). In such an example, the rigid sections  406   d  can be disposed between the first and second layers  432   d ,  434   d . Disposing the rigid sections  406   d  in the continuous sheet  402   d  can improve the aesthetics of the barrier  400   d , allows the first and second layers  432   d ,  434   d  to protect the rigid sections  406   d  from the environment, provide new means of securely coupling the rigid sections  406   d  to the continuous sheet  402   d , etc. 
     Referring to  FIG.  4 E , the barrier  400   e  includes a continuous sheet  402   e  and a plurality of rigid sections  406   e  that are disposed in the continuous sheet  402   e . For example, the continuous sheet  402   e  can include at least one first layer  432   e , at least one second layer  434   e , and at least one third layer  438   e  that is disposed between the first and second layers  432   e ,  434   e . Except as otherwise disclosed herein, the first, second, and third layers  432   e ,  434   e ,  438   e  can be the same or substantially similar to the first, second, and third layers  432   c ,  434   c ,  438   c  of  FIG.  4 C . In an example, the rigid sections  406   e  can be disposed between the third layer  438   e  and at least one of the first or second layers  432   e ,  434   e . In another example, the rigid sections  406   e  can be disposed in the third layer  438   e  (e.g., the third layer  438   e  includes at least two layers and the rigid sections  406   e  are disposed between the at least two layers of the third layer  438   e ). 
     It is noted that the barriers disclosed herein can exhibit arrangements other than the arrangements illustrated in  FIGS.  4 A- 4 E . For example, the barriers disclosed herein can include at least one rigid section attached to at least one of the two exterior surfaces of the continuous sheet and at least one rigid section disposed in the continuous sheet. In another example, the barriers disclosed herein can be formed from a continuous sheet that includes at least one first layer, at least one second layer, at least one third layer, and one or more additional layers. 
     In some embodiments, the barriers disclosed herein can include one or more mechanisms that are configured to improve the stability of the barriers when the barriers are in the at least partially expanded state.  FIG.  5    is a schematic front view of a portion of a barrier  500  illustrating several mechanisms that can be used to stabilize the barrier  500  when the barrier  500  is in the expanded state, according to an embodiment. Unless otherwise disclosed herein, the barrier  500  can be similar to any of the barriers disclosed herein. For example, the barrier  500  can be formed from a continuous sheet  502 , a plurality of rigid sections  506 , and a plurality of hinges  508 . The stability mechanisms illustrated in  FIG.  5    can be used in any of the barrier disclosed herein. 
     In an embodiment, the stability mechanisms that can be used to stabilize the barrier  500  can include at least one spacer  540 . The spacer  540  includes a narrow rigid panel that is formed from any of the rigid panel materials disclosed herein. The spacer  540  is attached to portions of the continuous sheet  502  are that adjacent to gaps formed between the rigid sections  506 . The spacers  540  can be configured to decrease the instability in the barrier  500  that is caused by the gaps. In an example, the spacer  540  is disposed on the mountain size 512 of the hinges  508  because the size of the gaps between the rigid sections  506  on the mountain side  512  of the hinges  508  may be greater than the gaps between the rigid sections  506  on the valley side (not shown) of the hinges  508 . It is noted that the spacers  540  can also be used to strengthen weak points in the barrier  500  that are formed by the gaps. 
     In an embodiment, the mechanism used to increase the stability of the barrier  500  can include positioning the hinges  508  to be substantially non-collinear. The hinges  508  are substantially non-collinear when a plurality of hinges  508  intersect a single gap (e.g., an unoccupied gap or a gap that is at least partially occupied by a spacer  540 ) and, at most, only one pair of hinges  508  are collinear. The hinges  508  are non-collinear when the longitudinal axes thereof are not parallel and/or are offset. Positioning the hinges  508  to be substantially non-collinear can increase the stability of the barrier  500  when the barrier  500  is in the expanded state. For example,  FIG.  5    illustrates a plurality of hinges  508  that meet at a single gap (e.g., the gap is at least partially occupied by the spacer  540 ) and that all of the hinges  508  that intersect at the gap are non-collinear. For instance,  FIG.  5    illustrates a first longitudinal axis  542  of one of the hinges  508  and a second longitudinal axis  544  of another one of the hinges  508 . As shown, the first longitudinal axis  542  is offset and non-parallel to the second longitudinal axis  544 . 
       FIG.  6    is a flow chart of a method  600  of forming any of the barriers disclosed herein, according to an embodiment. The method  600  can include blocks  605 ,  610 , and  615 . Except as otherwise disclosed herein, blocks  605 - 615  can be performed in any order, can be split into a plurality of different blocks, combined into a single block, supplemented, or deleted. Additionally, as discussed in more detail below, the method  600  can include one or more additional blocks. 
     Block  605  recites “providing a continuous sheet.” In an example, block  605  includes providing a sheet that includes a single layer or a plurality of layers. In another example, block  605  can include providing a sheet that is premade. In another example, block  605  can include providing a plurality of layers and forming the plurality of layers into the continuous sheet. In another example, block  605  can include providing any of the continuous sheets disclosed herein. 
     In an embodiment, block  605  can include providing at least one first layer that forms one of the exterior surfaces of the continuous sheet and at least one second layer that forms another one of the exterior surfaces of the continuous sheet. In such an embodiment, block  605  can also include providing at least one third layer that is disposed between the first and second layers. In an example, at least one of the first or second layers can be configured to form protection layers that protect the third layer from the environment. In such an example, at least one of the first or second layer can exhibit at least one of an abrasion resistance, water resistance, or ultra-violet light resistance that is greater than the third layer. 
     Block  610  recites “defining a plurality of rigid sections on the continuous sheet.” For example, block  610  can include providing any of the rigid panels disclosed herein and attaching the rigid panels to at least one of the exterior surfaces of the continuous sheet. In another example, block  610  can include providing any of the rigid panels disclosed herein and disposing the rigid panels in the continuous sheet. In another example, block  610  can include laminating at least one thermoplastic on a plurality of regions of the continuous sheet. In another example, block  610  can include impregnating a plurality of regions of the continuous sheet with at least one epoxy, resin, or another hardener. In another example, block  610  can include forming a plurality of stiches on a plurality of regions of the continuous sheet. 
     In an embodiment, the method  600  can include performing blocks  605  and  610  substantially simultaneously. For example, block  605  can include providing at least one first layer. After providing the at least one first layer, block  610  can include positioning a plurality of rigid panels to the one or more layers. After positioning the plurality of rigid panels on the one or more layers, block  605  can include disposing at least one second layer over the plurality of rigid panels and the first layer. Such an example can also include attaching the first and second layers together, attaching the rigid panels to the first and/or second layers, and/or attaching one or more additional layers to the first and second layers. 
     In an example, block  610  includes defining a plurality of rigid sections on the continuous sheet to form a Yoshimura or a modified Yoshimura pattern, a Miura-ori pattern, a square twist pattern, or a diamond pattern. In another example, block  610  can include forming a Yoshimura or a modified Yoshimura pattern exhibiting an even number of stories, such as a Yoshimura or a modified Yoshimura pattern having six stories. 
     Block  615  can include “forming a plurality of hinges from portions of the continuous sheet that are disposed between the plurality of rigid sections.” In an example, block  615  can be performed substantially simultaneously with blocks  605  and/or  610 . In an example, block  605  can include providing a continuous sheet that already includes a plurality of thick membrane folds formed therein or forming the thick membrane folds in the continuous sheet. In an example, block  615  can include forming a plurality of hinges that are substantially non-collinear. 
     In an example, the method  600  can include positioning at least one spacer on at least one mountain side of at least one of the plurality of hinges. In another example, the method  600  can include coupling a plurality of springs to the plurality of rigid sections. In another example, the method  600  can include positioning at least one brace to at least one of the plurality of rigid section. 
     The barriers disclosed herein can be modified for different applications by forming the barriers from materials that exhibit characteristics that are beneficial for specific applications or causing the barriers to exhibit a shape that provides characteristics that are beneficial for specific applications. The characteristics that are beneficial for a specific application, materials that provide the characteristics, and shapes that provide the characteristics may be known by a person having ordinary skill in the art. 
     In an embodiment, any of the barriers disclosed herein can be configured to be a ballistic barrier, such as a ballistic barrier that meets the same requirements as an armored vest that has an NIJ IIIa rating. Ballistic barriers solve a compelling need—protecting law enforcement, military, and innocent victims from dangerous situations. In most ballistic applications, portability is desired and quick deployment is essential. Possible applications for a ballistic barrier includes law enforcement, civilian, and military application. For example, a ballistic barrier that is configured for law enforcement applications can be configured to be a temporary barrier, be transported and stored in a small compacted state, and to be quickly expandable. In another example, ballistic barriers that are configured for military application can be less transportable and temporary than ballistic barriers that are configured for law enforcement applications since military barriers are often permanent blockades or barriers that are rated for very high power explosives or ammunition. 
     In an embodiment, any of the barriers disclosed herein can be construction barriers. Construction barriers include protective barriers that are configured to at least one of cover sidewalks, protect pedestrians, or to partition a construction site. 
     In an embodiment, any of the barriers disclosed herein can be acoustic barriers. Acoustic barriers can include sound absorbing barriers that reduce echo or amplifying barriers.
