     DETAILED DESCRIPTION 
     The following detailed description and the appended drawings describe and illustrate various example embodiments of multipurpose mats and hooks. The description and illustration of these examples are provided to enable one skilled in the art to make and use a multipurpose mat and/or hook. They are not intended to limit the scope of the claims in any manner. 
     The use of “e.g.,” “etc.,” “for instance,” “in example,” and “or” and grammatically related terms indicate non-exclusive alternatives without limitation, unless otherwise noted. The use of “optionally” and grammatically related terms means that the subsequently described element, event, feature, or circumstance may or may not be present or occur, and that the description includes instances where said element, event, feature, or circumstance occurs and instances where it does not. The use of “attached” refers to the fixed, releasable, or integrated association of two or more elements and/or devices. Thus, the term “attached” includes releasably attaching or fixedly attaching two or more elements and/or devices. 
     The use of “pliable” refers to the ability of a material to be bent, folded, twisted, manipulated, and/or adjusted by the hands of an average human being without the assistance of any tool or device between various configurations without damaging the element, feature, or object that the material forms. 
     Each of  FIGS. 1, 2, 3, and 4  illustrates an example embodiment of a multipurpose mat  10 . The multipurpose mat  10  comprises a lengthwise axis  11  and a mat body  12  that defines a first side  14 , a second side  16 , a third side  18 , a fourth side  20 , a first surface  22 , a second surface  24 , projections  26 , and chamfers  28 . 
     The first side  14  extends from the second side  16  to the fourth side  20 . The second side  16  extends from the first side  14  to the third side  18 . The third side  18  extends from the second side  16  to the fourth side  20 . The fourth side  20  extends from the first side  14  to the third side  18 . In the illustrated embodiment, the mat body  12  defines a first chamfer  28  at a  45  degree angle between the first side  14  and the second side  16 , a second chamfer  28  between the second side  16  and the third side  18 , a third chamfer  28  between the third side  18  and the fourth side  20 , and a fourth chamfer  28  between the first side  14  and the fourth side  20 . 
     In the illustrated embodiment, the first side  14  is parallel to the third side  18  and the second side  16  is parallel to the fourth side  20 . However, alternative embodiments of a multipurpose mat can include a first side that is not parallel to a third side and/or a second side that is not parallel to a fourth side. For example, alternative embodiments can include a side that is disposed at an angle to another side and/or a side that is non-planar (e.g., the side is curved). Each of the first side  14  and third side  18  has a length  15  equal to about  24  inches that extends from the second side  16  to the third side  20 . Each of the second side  16  and fourth side  20  has a length  17  equal to about  12  inches that extends from the first side  14  to the third side  18 . 
     Thus, the first side  14  and the third side  18  have the same length and the second side  16  and the fourth side  20  have the same length. The first side  14  has a length  15  that is different than the length  17  of the second side  16 . While a first side  14 , a second side  16 , a third side  18 , and a fourth side  20  have been illustrated, a multipurpose mat can include any suitable number of sides and can form any suitable geometric shape. Skilled artisans will be able to select a suitable number of sides to include on a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. Example number of sides considered suitable to include on a multipurpose mat include one, at least one, two, a plurality, three, four, five, six, seven, eight, and any other number considered suitable for a particular embodiment. 
     While the multipurpose mat  10  has been illustrated as including four chamfers  28 , each disposed at a 45 degree angle, a multipurpose mat can include any suitable number of chamfers disposed at any suitable angle. Example number of chamfers considered suitable to include on a multipurpose mat include one, at least one, two, a plurality, three, four, five, six, and any other number considered suitable for a particular embodiment. Example angles considered suitable to define a chamfer, or other feature, on a multipurpose mat include angles equal to, substantially equal to, about, less than, or greater than 45 degrees, 35 degrees, 25 degrees, 15 degrees, and any other angle considered suitable for a particular embodiment. Alternatively, a multipurpose mat can omit the inclusion of a chamfer and/or include other structural features as an alternative to a chamfer, such as a beveled edge, rounded edge, square edge, curved edge, or any other feature considered suitable for a particular embodiment. 
     Each of the first surface  22  and second surface  24  has a perimeter defined by the first side  14 , second side  16 , third side  18 , and fourth side  20 . In the illustrated embodiment, the perimeter of each of the first surface  22  and the second surface  24  is entirely defined by the first side  14 , second side  16 , third side  18 , and fourth side  20 , which include the illustrated chamfers  28 . However, alternative embodiments can include a first surface and/or second surface that are only partially defined by the sides of a multipurpose mat. In the illustrated embodiment, the first surface  22  is opposably facing the second surface  24 . However, alternative embodiments can include a first surface that is substantially opposably facing a second surface, or that is not opposably facing a second surface. 
     Each of the projections  26  extends from the first surface  22  and away from the second surface  24 . In the illustrated embodiment, the lengthwise axis of each projection  26  is disposed orthogonal to a plane that contains the lengthwise axis  11  of the multipurpose mat  10 . Thus, all of the projections  26  are parallel to one another. However, alternative embodiments can include a first projection that is not parallel to a second projection, or a first set of projections that is not parallel to a second set of projections. Each projection  26  has a length  25  equal to about 2 inches that is measured on an axis that is parallel to the lengthwise axis  11  of the multipurpose mat  10 . Each projection  26  is separated from an adjacent projection  26  by a distance  27  equal to about  2  inches that is measured on an axis that is parallel to the lengthwise axis  11  of the multipurpose mat  10 . While six projections  26  have been illustrated, a multipurpose mat can include any suitable number of projections, such as one, at least one, two, a plurality, three, four, five, six, seven, eight, a first set of projections, a second set of projections, and any other number considered suitable for a particular embodiment. Alternatively, a multipurpose mat can omit the inclusion of a projection. 
     While the projections  26  have been illustrated as having a rectangular cross-sectional configuration taken along a plane that contains the lengthwise axis  11  of the multipurpose mat  10  and that is disposed parallel to the first side  14 , a projection included on a multipurpose mat can have any suitable cross-sectional configuration. For example, the cross-sectional configuration of a projection taken along any suitable plane, such as one that contains the lengthwise axis of a multipurpose mat and that is parallel to the first side, can be curved, semicircular, semi-spherical, rectangular, square, or any other configuration considered suitable for a particular embodiment. In addition, while the projections  26  have been illustrated as formed from the body  12  of the multipurpose mat, a wall or projection of an embodiment described herein can be either an integrated component of the multipurpose mat or a separate element attached to the multipurpose mat using any suitable method of attachment, such as an adhesive. 
     Alternative embodiments can include one or more projections that extend from the second surface and away from the first surface. Each projection that extends from the second surface can have a width that is equal to, substantially equal to, about, greater than, or less than the width of a projection that extends from the first surface. Each projection that extends from the second surface can be disposed such that the lengthwise axis of the projection is disposed on a plane, or parallel to a plane, that contains the lengthwise axis of a projection that extends from the first surface and is orthogonal to the lengthwise axis of the multipurpose mat. 
     Any suitable material can be used to form a multipurpose mat, and skilled artisans will be able to select a suitable material according to a particular embodiment based on various considerations, including the material(s) that forms the surface on which the multipurpose mat is intended to be used. Example materials considered suitable to form a multipurpose mat include plastics, polymers, silicone, silicone-based materials, rubber, polyethylene, synthetic materials, pliable materials, flexible materials, semi-rigid materials, rigid materials, materials that provide a degree of attachment (e.g., releasable attachment) between an element placed on a multipurpose mat and the multipurpose mat, materials that provide a degree of attachment between a multipurpose mat and a surface upon which the multipurpose mat is intended to be used such that the multipurpose mat is releasably attached to the surface upon which the multipurpose mat is intended to be used, combinations of the materials described herein, and any other material considered suitable for a particular application. 
     A multipurpose mat can be formed of a material that is pliable such that the multipurpose mat can be moved between a first, open, configuration in which the edge between the first surface and the second side and the edge between the first surface and the fourth side are parallel to one another, substantially parallel to one another, and/or not contacting one another and a second, closed, configuration in which the edge between the first surface and the second side and the edge between the first surface and the fourth side are not parallel to one another and/or contact one another. Additionally, or alternative to the configurations described above, a multipurpose mat can be formed of a material that is pliable such that the multipurpose mat can be moved between a first, open, configuration in which the edge between the first surface and the first side and the edge between the first surface and the third side are parallel to one another, substantially parallel to one another, and/or not contacting one another and a second, closed, configuration in which the edge between the first surface and the first side and the edge between the first surface and the third side are not parallel to one another and/or contact one another. For example, a multipurpose mat can be formed of a pliable material such that the multipurpose mat can be folded. In the second configuration, the second surface of a multipurpose mat will form a teardrop configuration. For example, when the edge between the first surface and the first side and the edge between the first surface and the third side are brought into contact with one another, each of the second and fourth sides will be curved and form a teardrop configuration. Alternatively, when the edge between the first surface and the second side and the edge between the first surface and the fourth side are brought into contact with one another, each of the first and third sides will be curved and form a teardrop configuration. 
     When a multipurpose mat is formed of a pliable material, it is configured to conform the second surface of the multipurpose mat to the structural configuration of the surface on which the multipurpose mat is disposed without any external forces being applied to the multipurpose mat (e.g., the second surface of the multipurpose mat will form a negative of the surface on which it is placed). For example, when a multipurpose mat is disposed on the surface of an airplane, or jet, such as an airfoil (e.g., wing of an airplane, or jet), the second surface of the multipurpose mat is configured to conform to the surface of the airplane or jet without external forces being applied to the multipurpose mat. In embodiments in which a multipurpose mat is disposed on a surface, such as an airfoil, such as the wing of an airplane or a jet, the surface can comprise any suitable surface and have any structural configuration, and skilled artisans will be able to select a suitable surface to position a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. Examples of suitable surfaces considered suitable to position a multipurpose mat include flat surfaces, non-flat surfaces, curved surfaces, surfaces that define one or more openings and/or recesses, curved airfoils, and any other surface considered suitable for a particular embodiment. 
     When a multipurpose mat is positioned on a surface, one or more objects, tools, and/or devices can be positioned on the multipurpose mat. For example, when a multipurpose mat is disposed on a non-flat surface and one or more objects, tools, and/or devices (e.g., objects, tool, and/or devices that are rigid relative to the multipurpose mat) are disposed on the multipurpose mat, such as on the first surface, one or more projections, a wall, the one or more objects, tools, and/or devices, unless formed of a pliable material, will not conform to the structural configuration of the surface on which the multipurpose mat is disposed. Thus, the multipurpose mat will have a first configuration and the one or more objects, tools, and/or devices will have a second configuration that is different than the first configuration. 
     The material that forms a multipurpose mat can have any suitable durometer hardness and skilled artisans will be able to select a material to form a multipurpose mat that has a suitable durometer hardness according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. Examples of suitable durometer hardnesses considered suitable for a material that forms a multipurpose mat include materials that have a durometer hardness equal to, substantially equal to, about, less than, or greater than, a 40 durometer hardness, a 60 durometer hardness, a durometer hardness between 40 and 60, and materials that have any other durometer hardness considered suitable for a particular application. Any suitable scale can used to measure the durometer hardness of a material, such as the Shore A and Shore D scales. 
     A multipurpose mat can be formed using any suitable technique, and skilled artisans will be able to select a suitable technique to form a multipurpose mat according to a particular embodiment based on various considerations, including the material(s) that forms the multipurpose mat. Example techniques considered suitable to form a multipurpose mat include injection molding and/or cast molding. 
     A multipurpose mat can be formed of a material having any suitable color, and skilled artisans will be able to select a suitable color for a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. Example colors considered suitable to form a multipurpose mat include, but are not limited to, green, yellow, grey, brown, white, black, red, blue, and any other color considered suitable for a particular application. A multipurpose mat can optionally be formed of a color that is based on the material that forms the multipurpose mat, the type of surface on which the multipurpose mat is intended to be used (e.g., the type of material that forms the surface on which the multipurpose mat is intended to be used), the coefficient of friction between the multipurpose mat and the surface on which the multipurpose mat is intended to be used, and/or on the color of the surface on which the multipurpose mat is intended to be used. For example, if the multipurpose mat is formed of rubber, the material that forms the multipurpose mat can be colored green. Alternatively, if the multipurpose mat is formed of a synthetic material, the material that forms the multipurpose mat can be colored red. In embodiments in which the color of the material that forms the multipurpose mat is based on the color of the surface on which the multipurpose mat is intended to be used, the material that forms the multipurpose mat can be different than the color of the surface on which the multipurpose mat is intended to be used. For example, the multipurpose mat can be formed of a material that provides a high degree of contrast between the multipurpose mat and the surface on which the multipurpose mat is intended to be used. 
     In the illustrated embodiment, example dimensions for various structural elements of the multipurpose mat  10  have been described. In addition, various structural arrangements of features have been illustrated and described. It is to be understood, however, that any suitable dimensions and structural arrangements of features can be used to form a multipurpose mat, and skilled artisans will be able to select suitable dimensions and structural arrangements of features for a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. For example, each dimension can alternatively be a dimension that is equal to, substantially equal to, about, greater than, less than, or near, the dimension described. For example, any of the edges described and/or illustrated herein can have a radius of curvature or chamfer, such as a radius of curvature equal to about 0.06 inches or 0.05 inches, or a chamfer equal to about 2.0 inches or 0.03 inches. 
     For example, a first side and third side of a multipurpose mat can have a length equal to, substantially equal to, about, less than, or greater than 24 inches and a second side and fourth side of a multipurpose mat can have a length equal to, substantially equal to, about, less than, or greater than 12 inches. Alternative embodiments can include a first side than has a length that is different than the length of a third side and/or a second side that has a length that is different than a fourth side. A projection and/or the space between adjacent projections included on a multipurpose mat can have a length that is equal to, substantially equal to, about, less than, or greater than 2 inches. Alternative to the configuration illustrated and described, a first projection can have a first length and a second projection can have a second length that is different than the first length and/or a first projection can be separated from an adjacent projection a first distance and a third projection can be separated from a fourth projection by a second distance that is different than the first distance. 
     Each of  FIGS. 5, 6, and 7  illustrates another example embodiment of a multipurpose mat  110 . Multipurpose mat  110  is similar to multipurpose mat  10  illustrated in  FIGS. 1, 2, 3, and 4  and described above, except as detailed below. Reference numbers in  FIGS. 5, 6, and 7  refer to the same structural element or feature referenced by the same number in  FIGS. 1, 2, 3, and 4 , offset by 100. Thus, multipurpose mat  110  comprises a lengthwise axis  111  and a mat body  112  that defines a first side  114 , a second side  116 , a third side  118 , a fourth side  120 , a first surface  122 , a second surface  124 , projections  126 , and chamfers  128 . 
     In the illustrated embodiment, each of the first side  114  and the third side  118  has a length equal to about  48  inches that extends from the second side  116  to the fourth side  120  and each of the second side  116  and the fourth side  120  has a length equal to about 24 inches that extends from the first side  14  to the third side  18 . In addition, the multipurpose mat  110  includes twelve projections  126 . Each projection  126  is disposed from an adjacent projection  126  by a distance equal to about 2 inches measured on an axis that is parallel to the lengthwise axis  111  of the multipurpose mat  110 . 
     In the illustrated embodiment, example dimensions for various structural elements of the multipurpose mat  110  have been described. In addition, various structural arrangements of features have been illustrated and described. It is to be understood, however, that any suitable dimensions and structural arrangements of features can be used to form a multipurpose mat, and skilled artisans will be able to select suitable dimensions and structural arrangements of features for a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. For example, each dimension can alternatively be a dimension that is equal to, substantially equal to, about, greater than, less than, or near, the dimension described. 
     Each of  FIGS. 8, 9, 10, 11, 12, 13, and 14  illustrates another example embodiment of a multipurpose mat  210 . Multipurpose mat  210  is similar to multipurpose mat  10  illustrated in  FIGS. 1, 2, 3, and 4  and described above, except as detailed below. Reference numbers in  FIGS. 8, 9, 10, 11, 12, 13, and 14  refer to the same structural element or feature referenced by the same number in  FIGS. 1, 2, 3, and 4 , offset by 200. Thus, multipurpose mat  210  comprises a lengthwise axis  211  and a mat body  212  that defines a first side  214 , a second side  216 , a third side  218 , a fourth side  220 , a first surface  222 , a second surface  224 , and projections  226 . 
     In the illustrated embodiment, multipurpose mat  210  omits the inclusion of chamfers (e.g., chamfers  28 ) and includes rounded corners  228  between the first side  214  and second side  216 , the second side  216  and the third side  218 , the third side  218  and the fourth side  220 , and the fourth side  220  and the first side  214 . The rounded corners included on a multipurpose mat can have any suitable radius of curvature, such as a radius of curvature that is equal to, substantially equal to, about, greater than, or less than 1.0 inch, 2.0 inches, and any other radius of curvature considered suitable for a particular embodiment. Alternatively, rounded corners  228  can be omitted and a multipurpose mat can be formed such that a first side is perpendicular to a second side, a second side is perpendicular to a third side, a third side is perpendicular to a fourth side, and/or a fourth side is perpendicular to a first side.

However, alternative embodiments can include a first recess and a second recess that extend only into the body of the multipurpose mat. The first recess  250  also extends from the first side  214  and into the body  212  of the multipurpose mat  210  toward the third side  218 . Each of the first recess  250  and second recess  252  is sized and configured to receive a portion of hook  300 , as described in more detail below. 
     Each of the first recess  250  and second recess  252  extends from the fourth side  220  toward the second side  216  and terminates at a location between the fourth side  220  and the second side  216 . In the illustrated embodiment, the lengthwise axis of the first recess  250  is parallel to the lengthwise axis of the second recess  252 . Each of the first recess  250  and second recess  252  terminates a distance from the second side  216  equal to about 5.0 inches. This structural arrangement provides a mechanism for positioning the hook  300  at a desired location along the length of multipurpose mat  210  and provides a mechanical stop to advancement of the hook  300  into the multipurpose mat  210 . The first recess  250  interrupts the second surface  224  by creating an opening that extends from the first side  214  toward the third side  218  a length equal to about 0.30 inches measured along the fourth side  220 .

At the second surface  224 , the projection  228  has two ends that have a radius of curvature equal to about 0.02 inches. The projection has a length that extends from the first recess  250  to the second recess  252  that is equal to about 0.645 inches. 
     While two recesses  250 ,  252  have been illustrated, a multipurpose mat can include any suitable number of recesses, such as one, at least one, two, a plurality, three, four, five, six, seven, eight, and any other number considered suitable for a particular embodiment. While each of the first recess  250  and second recess  252  has been described as extending from the fourth side  220  toward the second side  216 , a recess can extend from any suitable portion of a multipurpose mat. For example, a recess can extend from the second side toward the fourth side, or from any other location considered suitable for a particular embodiment. 
     In the illustrated embodiment, example dimensions for various structural elements of the multipurpose mat  210  have been described. In addition, various structural arrangements of features have been illustrated and described. It is to be understood, however, that any suitable dimensions and structural arrangements of features can be used to form a multipurpose mat, and skilled artisans will be able to select suitable dimensions and structural arrangements of features for a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. For example, each dimension can alternatively be a dimension that is equal to, substantially equal to, about, greater than, less than, or near, the dimension described. 
     Each of  FIGS. 15, 16, 17, and 18  illustrates an example embodiment of a hook  300  that can be used with a multipurpose mat, such as multipurpose mat  210 .

     Recess  316  extends into the elongate body  302  from the first surface  312  toward the second surface  314  and from the second side  306  to the fourth side  310 . The recess  316  extends from the first surface  312  and into the body  302  of the hook  300  a distance equal to about 0.125 inches. Recess  316  is sized and configured to receive the projection  258  defined by multipurpose mat  210 . Recess  316  defines a first curved surface  322  and a second curved surface  324 . The first curved surface  322  is complementary to first curved surface  254  and the second curved surface  324  is complementary to second curved surface  256 . In the illustrated embodiment, each of the first curved surface  322  and second curved surface  324  has a radius of curvature equal to about 0.02 inches and the two edges between the first surface  312  and the recess  316  have a radius of curvature equal to about 0.03 inches. In the illustrated embodiment, the first surface  312  extends from the first side  304  toward the third side  308  a distance equal to about 0.30 inches to recess  316  and extends from the recess  316  to the third side  308  a distance equal to about 0.18 inches. The recess  316  tapers from the base of the recess  316  toward the first surface  312  such that each side of the recess is disposed at a 45 degree angle relative to a plane that contains the first surface  312 . 
     Projection  318  has a first portion  330  and a second portion  332 . The first portion  330  extends from the second surface  314  and away from the first surface  312  to a first projection end  334  a length  331  that is equal to about 0.25 inches. The first portion  330  has a thickness equal to about 0.125 inches that extends from the first side  304  toward the third side  308 . The second portion  332  extends from the first projection end  334  toward the third side  308  to a second projection end  336  a length that is equal to about 0.1875 inches. The second portion  332  has a thickness equal to about 0.125 inches that extends from the first projection end  334  toward the second surface  314 . The second portion  332  extends from the first projection end  334  parallel to the second surface  314 . However, other angles are considered suitable. 
     Each notch  320  extends through the first portion  330  and second portion  332  of the projection  318  and into the elongate body  302  such that the surfaces of the first portion  330  and the second portion  332  of the projection  318  and the surface of the first side  303  are interrupted. However, a notch can have any suitable depth. For example, a notch can extend through a portion, or the entirety, of a first portion of a projection, a second portion of a projection, and/or an elongate body. While two notches  320  have been illustrated, any suitable number of notches can be included on a hook, such as one, at least one, two, a plurality, three, four, five, and any other number considered suitable for a particular application. Alternatively, notches can be omitted from a multipurpose mat. 
     A first notch  320  is disposed a distance from the fourth side  310  equal to about 5.125 inches and a second notch  320  is disposed a distance from the fourth side  310  equal to about 14.185 inches. In the illustrated embodiment, each notch  320  has a length measured on an axis parallel to the lengthwise axis  301  of the hook  300  that is equal to about 0.75 inches. 
     Any suitable material can be used to form a hook, and skilled artisans will be able to select a suitable material to form a hook according to a particular embodiment based on various considerations, including the material(s) that forms the surface on which the hook is intended to be used. Example materials considered suitable to form a hook include plastics, polymers, silicone-based materials, rubber, polyethylene, flexible materials, rigid materials, and any other material considered suitable for a particular application. For example, a hook can be formed of a first material and a multipurpose mat intended to be releasably attached to the hook can be formed of a second material that is the same as, or different than, the first material. 
     A hook can be formed using any suitable technique, and skilled artisans will be able to select a suitable technique to form a hook according to a particular embodiment based on various considerations, including the material(s) that forms the hook. An example technique considered suitable includes injection molding. 
     In the illustrated embodiment, example dimensions for various structural elements of the hook  300  have been described. In addition, various structural arrangements of features have been illustrated and described. It is to be understood, however, that any suitable dimensions and structural arrangements of features can be used to form a hook, and skilled artisans will be able to select suitable dimensions and structural arrangements of features for a hook according to a particular embodiment based on various considerations, including the intended use of the hook. For example, each dimension can alternatively be a dimension that is equal to, substantially equal to, about, greater than, less than, or near, the dimension described. 
       FIGS. 19 and 20  illustrate the hook  300  releasably attached to the multipurpose mat  210 . In use, the projection  258  is introduced into recess  316  defined by hook  300  and the hook  300  is advanced into multipurpose mat  210  until the second side  306  of the hook  300  contacts the end of the first recess  250  and second recess  252 . In the illustrated embodiment, the hook  300  is formed of a first material and the multipurpose mat  210  is formed of a second material. The first material is different from the second material and is relatively more rigid than the second material (e.g., the first material has a durometer hardness that is greater than the durometer hardness of the second material). Alternatively, the first material can be the same as the second material. While multipurpose mat  210  and hook  300  have been described as separate elements, a multipurpose mat and hook can be formed as integral components. 
     In the illustrated embodiment, a portion of hook  300  extends from the second surface  224  of multipurpose mat  210  a length  301 ′. Length  301 ′ can comprise any suitable distance and skilled artisans will be able to select a suitable distance for a hook to extend from the second surface of a multipurpose mat when attached to the multipurpose mat according to a particular embodiment based on various considerations, including the structural arrangement of an intended workspace. Example lengths considered suitable for a hook to extend from the second surface of a multipurpose mat include lengths equal to 0.125 inches, equal to about 0.125 inches, about 0.125 inches, greater than 0.125 inches, less than 0.125 inches, and any other length considered suitable for a particular embodiment. For example, as illustrated in  FIG. 27 , a jet  800  has a gun opening  802  that has a recessed edge  802 ′ that is recessed relative to the outer surface of the jet  800 . When hook  300  extends from the second surface  224  it can be sized and configured to be disposed entirely within, or partially within, recessed edge  802 ′ to provide support for the multipurpose mat  300 . 
     In the illustrated embodiment, example dimensions for various structural elements of the multipurpose mat  210  and hook  300  have been described. In addition, various structural arrangements of features have been illustrated and described. It is to be understood, however, that any suitable dimensions and structural arrangements of features can be used to form a multipurpose mat and/or hook, and skilled artisans will be able to select suitable dimensions and structural arrangements of features for a multipurpose mat and/or hook according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat and/or hook. For example, each dimension can alternatively be a dimension that is equal to, substantially equal to, about, greater than, less than, or near, the dimension described.

Thus, multipurpose mat  810  comprises a lengthwise axis  811  and a body  812  that defines a first side  814 , a second side  816 , a third side  818 , a fourth side  820 , a first surface  822 , and a second surface  824 . 
     In the illustrated embodiment, the first surface  822  is opposably positioned from the second surface  824  such that the multipurpose mat  810  has a thickness that extends from the first surface  822  to the second surface  824  that is equal to about 0.25 inches. The length of the multipurpose mat  810  that extends from the second side  816  to the fourth side  820 , including the length of chamfers  828 , is equal to about 24 inches. The length of the multipurpose mat  810  that extends from the first side  814  to the third side  818 , including the length of chamfers  828 , is equal to about 12 inches. 
     In the illustrated embodiment, alternative to defining projections, such as those illustrated in  FIGS. 1, 2, 3, and 4  (e.g., projections  26 ), multipurpose mat  810  defines a wall  830 , a first set of projections  832 , and a second set of projections  834 . The wall  830  extends from the first surface  822  and away from the second surface  824  a first distance  851 .

     Each projection of the first set of projections  832  extends from the first surface  822  and away from the second surface  824  a second distance  853 . In the illustrated embodiment, the second distance  853  is less than the first distance  851  and is equal to about 0.13 inches. Each projection of the first set of projections  832  extends from the first portion of the wall  830  that extends along the first side  814  to the third portion of the wall  830  that extends along the third side  818 . In the embodiment illustrated, a first projection  836  of the first set of projections  832  is disposed on a first axis, a second projection  838  of the first set of projections  832  is disposed on a second axis, a third projection  840  of the first set of projections  832  is disposed on a third axis, and a fourth projection  842  of the first set of projections  832  is disposed on a fourth axis. The first axis is disposed orthogonal to a plane that contains the lengthwise axis  811  and is parallel to the second axis, third axis, and the fourth axis. Thus, the first projection  836 , the second projection  838 , the third projection  840 , and the fourth projection  842  are parallel to one another. However, alternative embodiments can include a first projection that is disposed on a first axis that is not disposed orthogonal to a plane that contains the lengthwise axis of a multipurpose mat and/or that is not parallel to a second axis, third axis, and/or fourth axis. 
     In the illustrated embodiment, each projection of the first set of projections  832  has a thickness equal to about 0.25 inches as measured on an axis that is parallel to the lengthwise axis  811  of the multipurpose mat  810 . The first projection  836  is separated from the adjacent second projection  838  by a distance equal to about 2.75 inches. The second projection  838  is separated from the adjacent third projection  840  by a distance equal to about 2.75 inches. The third projection  840  is separated from the adjacent fourth projection  842  by a distance equal to about 2.75 inches. The fourth projection  842  is separated from the adjacent wall  830  (e.g., second portion of the wall  830  that extends along the second side  816 ) by a distance equal to about 2.5 inches. 
     Each projection of the second set of projections  834  extends from the first surface  822  and away from the second surface  824  a third distance  855  that is less than the first distance  851 . Each projection of the second set of projections  834  extends from the fourth portion of the wall  830  that extends along the fourth side  820  to the first projection  836  of the first set of projections  832 . In the embodiment illustrated, a first projection  844  of the second set of projections  834  is disposed on a first axis, a second projection  846  of the second set of projections  834  is disposed on a second axis, and a third projection  848  of the second set of projections  834  is disposed on a third axis. The first axis is disposed parallel to the second axis and the third axis. Thus, the first projection  844 , the second projection  846 , and the third projection  848  are parallel to one another. However, alternative embodiments can include a first projection that is disposed on a first axis that is not parallel to a second axis and/or third axis. Each of the first projection  844 , second projection  846 , and third projection  848  of the second set of projections  834  is disposed at an angle to the first projection  836  of the first set of projections  832 . In the illustrated embodiment, the first projection  844 , second projection  846 , and third projection  848  of the second set of projections  834  is disposed at an orthogonal angle to the first projection  836  of the first set of projections  832 . Alternatively, each of the first projection, second projection, and/or third projection of a second set of projections can be disposed at other angles relative to the first projection of a first set of projections (e.g., 45 degrees), or a projection included on a multipurpose mat can be curved. 
     In the illustrated embodiment, each projection of the second set of projections  834  has a thickness equal to about 0.25 inches as measured on an axis that is disposed on a plane that is orthogonal to the lengthwise axis  811 . The first projection  844  is separated from the adjacent wall  830  (e.g., fourth portion of the wall  830  that extends along the fourth side  820 ) by a distance equal to about 2.63 inches. The first projection  844  is separated from the adjacent second projection  846  by a distance equal to about 2.75 inches. The second projection  846  is separated from the adjacent third projection  848  by a distance equal to about 2.75 inches. 
     In the embodiment illustrated, the first distance  851  the wall  830  extends from the first surface  822  and away from the second surface  824  is greater than the second distance  853  the first set of projections  832  extends from the first surface  822  and the third distance  855  the second set of projections  834  extends from the first surface  822 . The wall  830 , each projection of the first set of projections  832 , and each projection of the second set of projections  834 , has a rounded outer surface. For example, each projection of the first set of projections  832  and each projection of the second set of projection  834  can have a radius of curvature at its apex that is equal to about 0.13 inches. Alternatively, the wall, each projection of the first set of projections, and/or each projection of the second set of projections included on a multipurpose mat can have any suitable cross-sectional configuration, such as rectangular, square, or curved. 
     While the first set of projections  832  has been illustrated as having four projections and the second set of projections  834  has been illustrated as having three projections, the first set of projections and second set of projections included on a multipurpose mat can include any suitable number of projections. Skilled artisans will be able to select a suitable number of projections to include on a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. Example number of projections considered suitable to include in a first and/or second set of projections included on a multipurpose mat include one, at least one, two, a plurality, three, four, five, and any other number considered suitable for a particular embodiment. Alternative embodiments can omit the inclusion of the first set of projections and/or second set of projections. 
     In the illustrated embodiment, the multipurpose mat  810  is formed of a pliable material such that the multipurpose mat  810  can be moved between a first, open, configuration in which the first portion of the wall  830  that extends along the first side  814  and the third portion of the wall  830  that extends along the third side  818  are parallel to one another and do not contact one another and a second, closed, configuration in which the first portion of the wall  830  that extends along the first side  814  contacts the third portion of the wall  830  that extends along the third side  818 . Alternatively, or in combination with the configuration described above, the multipurpose mat  810  can be formed of a pliable material such that the multipurpose mat  810  can be moved between a first, open, configuration in which the second portion of the wall  830  that extends along the second side  816  and the fourth portion of the wall  830  that extends along the fourth side  820  are parallel to one another and do not contact one another and a second, closed, configuration in which the second portion of the wall  830  that extends along the second side  816  contacts the fourth portion of the wall  830  that extends along the fourth side  820 . For example, a multipurpose mat can be formed of a pliable material such that the multipurpose mat can be folded. In the second configuration, the second surface of a multipurpose mat will form a teardrop configuration. For example, when the first portion of the wall  830  that extends along the first side  814  and the third portion of the wall  830  that extends along the third side  818  are brought into contact with one another, each of the second and fourth portions of the wall  830  will be curved and form a teardrop configuration. Alternatively, when the second portion of the wall  830  that extends along the second side  816  and the fourth portion of the wall that extends along the fourth side  820  are brought into contact with one another, each of the first and third portions of the wall  830  will be curved and form a teardrop configuration. 
     A multipurpose mat, such as those that are formed of a pliable material, can optionally include one or more locking mechanism that are configured to lock the multipurpose mat in the second configuration. A multipurpose mat can include any suitable locking mechanism and skilled artisans will be able to select a suitable locking mechanism to include on a multipurpose mat according to a particular embodiment based on various considerations, including the material that forms the multipurpose mat. Example locking mechanisms considered suitable to include on a multipurpose mat include snap fit structures, one or more hook and loop elements, first and second elements that have corresponding interlocking teeth (e.g., zipper), one or more clasps, any combination of the locking mechanisms described herein, and any other locking mechanism considered suitable for a particular embodiment. 
     In the illustrated embodiment, example dimensions for various structural elements of the multipurpose mat  810  have been described. In addition, various structural arrangements of features have been illustrated and described. It is to be understood, however, that any suitable dimensions and structural arrangements of features can be used to form a multipurpose mat, and skilled artisans will be able to select suitable dimensions and structural arrangements of features for a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. For example, each dimension can alternatively be a dimension that is equal to, substantially equal to, about, greater than, less than, or near, the dimension described.

Thus, multipurpose mat  1210  comprises a lengthwise axis  1211  and a body  1212  that defines a first side  1214 , a second side  1216 , a third side  1218 , a fourth side  1220 , a first surface  1222 , a second surface  1224 , a wall  1230 , a first set of projections  1231 , and a second set of projections  1233 . 
     In the illustrated embodiment, the multipurpose mat  1210  includes rounded corners  1228 . The wall  1230  extends from the first surface  1222  and away from the second surface  1224  a first distance  1251 . The first set of projections  1231  includes a first projection  1232 , a second projection  1234 , a third projection  1236 , a fourth projection  1238 , a fifth projection  1240 , and a sixth projection  1242 . The first set of projections  1231  extends from the first surface  1222  and away from the second surface  1224  a second distance  1253  that is equal to the first distance  1251 . 
     Each of the first projection  1232  and the fourth projection  1238  extends from the first portion of the wall  1230  that extends along the first side  1214  to the third portion of the wall  1230  that extends along the third side  1218 . Alternatively, the first projection  1232  and/or fourth projection  1238  can extend from a rounded corner  1228 . 
     A first portion  1260  and a second portion  1262  of the first projection  1232  are curved. The first portion  1260  is curved such that the first projection  1232  extends toward a plane that contains the second portion of the wall  1230  that extends along the second side  1216 . The second portion  1262  is curved such that the first projection  1232  extends toward a plane that contains the second portion of the wall  1230  that extends along the second side  1216 . A first portion  1264  and a second portion  1266  of the fourth projection  1238  are curved. The first portion  1264  is curved such that the fourth projection  1238  extends toward a plane that contains the fourth portion of the wall  1230  that extends along the fourth side  1220 . The second portion  1266  is curved such that the fourth projection  1238  extends toward a plane that contains the fourth portion of the wall  1230  that extends along the fourth side  1220 . In the illustrated embodiment, the portions of the first projection  1232  and the fourth projection  1238  that are linear are disposed parallel to one another and are disposed orthogonal to a plane that contains the lengthwise axis  1211  of the multipurpose mat  1210 . 
     Each of the second projection  1234  and the third projection  1236  extends from the first projection  1232  to the second portion of the wall  1230  that extends along the second side  1216 . Each of the second projection  1234  and the third projection  1236  is curved. The second projection  1234  is curved such that it extends from the wall  1230  toward the third projection  1236  to a midpoint and from the midpoint and away from the third projection  1236  to the first projection  1232 . The third projection  1236  is curved such that it extends from the wall  1230  toward the second projection  1234  to a midpoint and from the midpoint and away from the second projection  1234  to the first projection  1232 . 
     In the illustrated embodiment, the wall  1230 , the first projection  1232 , and the second projection  1234  cooperatively define a first cavity  1250  and the wall  1230 , the first projection  1232 , and the third projection  1236  cooperatively define a second cavity  1252 . In the illustrated embodiment, the first cavity  1250  has the same dimensions as the second cavity  1252  and each of the first cavity  1250  and the second cavity  1252  is cylindrical.

     In the illustrated embodiment, the wall  1230 , the fourth projection  1238 , and the fifth projection  1240  cooperatively define a fourth cavity  1256  and the wall  1230 , the fourth projection  1238 , and the sixth projection  1242  cooperatively define a fifth cavity  1258 . In the illustrated embodiment, the fourth cavity  1256  has the same dimensions as the fifth cavity  1258  and each of the fourth projection  1238  and the fifth projection  1240  is cylindrical. Each of the fourth cavity  1256  and the fifth cavity  1258  is sized and configured to receive one or more objects, tools, parts, and/or devices, such as a pop can. For example, each of a first cavity and a second cavity defined by a multipurpose mat can have a diameter that is about, equal to, substantially equal to, greater than, or less than 2.5 inches. 
     The wall  1230 , the fourth projection  1238 , the fifth projection  1240 , and the sixth projection  1242  cooperatively define a sixth cavity  1260  that is adjacent to the fourth cavity  1256  and the fifth cavity  1258 . The sixth cavity  1260  is sized and configured to receive one or more objects, tools, parts, and/or devices, such as a cell phone. For example, a sixth cavity defined by a multipurpose mat can have length measured along an axis that is parallel to the lengthwise axis of the multipurpose mat that is about, equal to, substantially equal to, greater than, or less than 2.31 inches and a width measured along an axis that is disposed on a plane that is orthogonal to the lengthwise axis of the multipurpose mat that is about, equal to, substantially equal to, greater than, or less than 4.54 inches. 
     The second set of projections  1233  comprises a seventh projection  1244 , eighth projection  1246 , and a ninth projection  1248 . Each of the seventh projection  1244 , eighth projection  1246 , and ninth projection  1248  extends from the first surface  1222  and away from the second surface  1224  a third distance  1255 . In the illustrated embodiment, the third distance  1255  is less than the first distance  1251  and the second distance  1253 . Alternatively, the third distance  1255  can be substantially equal to, greater than, or less than the first distance  1251  and/or second distance  1253 . 
     Each of the seventh projection  1244  and eighth projection  1246  extends from the first projection  1232  to the fourth projection  1238 . The seventh projection  1244  and eighth projection  1246  are parallel to one another and to the lengthwise axis  1211  of the multipurpose mat  1210 . The seventh projection  1244  and the eighth projection  1246  are disposed orthogonal to the first projection  1232 . The ninth projection  1248  extends from the seventh projection  1244  to the eighth projection  1246  and is disposed orthogonal to the seventh projection  1244 . 
     While the projections illustrated in  FIGS. 42 and 43  have been illustrated as being disposed in a particular configuration, the projections defined by the body of a multipurpose mat can be arranged in any suitable configuration. Skilled artisans will be able to select a suitable configuration for one or more projections defined by the body of a multipurpose mat according to a particular embodiment based on various considerations, including the dimensions of a component intended to be disposed on a multipurpose mat (e.g., dimensions of a tool). Alternatively, multipurpose mat  1210  can omit the inclusion of one or more of the illustrated projections. For example multipurpose mat  1210  can omit the inclusion of one or more of the first projection  1232 , the second projection  1234 , the third projection  1236 , the fourth projection  1238 , the fifth projection  1240 , the sixth projection  1242 , the seventh projection  1244 , the eighth projection  1246 , and/or the ninth projection  1248 . 
     In the illustrated embodiment, example dimensions for various structural elements of the multipurpose mat  1210  have been described. In addition, various structural arrangements of features have been illustrated and described. It is to be understood, however, that any suitable dimensions and structural arrangements of features can be used to form a multipurpose mat, and skilled artisans will be able to select suitable dimensions and structural arrangements of features for a multipurpose mat according to a particular embodiment based on various considerations, including the intended use of the multipurpose mat. For example, each dimension can alternatively be a dimension that is equal to, substantially equal to, about, greater than, less than, or near, the dimension described. 
     Any of the herein described multipurpose mats and/or hooks can include one or more magnets disposed within the body of the multipurpose mat and/or hook, or disposed on a surface of the body of the multipurpose mat and/or hook. The one or more magnets can be formed of any suitable material and be disposed at suitable location on, or within, a multipurpose mat and/or hook. For example, a first magnet can be disposed within the body, or on a surface, of a multipurpose mat and a second magnet can be disposed within the body, or on the surface, of the multipurpose mat. The first magnet can be opposably positioned from the second magnet relative to a plane that contains the lengthwise axis of the multipurpose mat. Alternatively, the first magnet can be opposably positioned from the second magnet relative to a plane that is disposed orthogonal to the lengthwise axis of a multipurpose mat. 
     Any of the embodiments described herein can be used for any suitable purpose, and skilled artisans will be able to select a suitable purpose for a multipurpose mat and/or a multipurpose mat and associated hook according to a particular embodiment based on various considerations, including the procedure intended to be completed. For example,  FIG. 27  illustrates a jet  800  upon which an embodiment of a multipurpose mat or a multipurpose mat and associated hook, such as those described and illustrated herein, can be used. 
     Jet  800  has a gun opening  802  that provides access to a gun housing  804 . In use, a multipurpose mat, such as the embodiment described and illustrated herein, can be disposed, for example, at location  806  or location  808  to provide footing and/or temporary storage for one or more objects, tools, and/or devices while maintenance is being provided to the jet  800 . When placed at location  806  or  808  on the jet  800 , the second surface of the multipurpose mat will conform to the structural arrangement of the surface on which the multipurpose mat is disposed and will provide releasable attachment of the multipurpose mat to the surface on which it is disposed. This is considered advantageous because it reduces, or eliminates, foreign object damage to the jet  800  while it is being maintained. Optionally, more than one multipurpose mat or multipurpose mat and associated hook can be used in combination. For example, a first multipurpose mat can be disposed at location  806  and a second multipurpose mat can be disposed at location  808 . Optionally, when included, a hook can be disposed along a portion of the perimeter of an opening (e.g., gun opening  802 ) to provide attachment of a multipurpose mat near, or at, a workspace. 
     While an example use of the multipurpose mat or a multipurpose mat and associated hook has been described, a multipurpose mat or a multipurpose mat and associated hook can be used in any desired manner. Skilled artisans will be able to select a suitable use for a multipurpose mat or a multipurpose mat and associated hook according to a particular embodiment based on various considerations, including the procedure intended to be performed.
