     DETAILED DESCRIPTION 
     Additional features and advantages of the presently disclosed device will be set forth in the detailed description, which follows and will be apparent to those skilled in the art from the description, or recognized by practicing the device as described in the following description, together with the claims and appended drawings. 
     For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the concepts as oriented in  FIG.  1   . However, it is to be understood that the concepts may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. 
     As used herein, the term “and/or,” when used in a list of two or more items, means that any one of the listed items can be employed by itself, or any combination of two or more of the listed items, can be employed. For example, if a composition is described as containing components A, B, and/or C, the composition can contain A alone; B alone; C alone; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination. 
     As used herein, the term “about” means that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. When the term “about” is used in describing a value or an end-point of a range, the disclosure should be understood to include the specific value or end-point referred to. Whether or not a numerical value or end-point of a range in the specification recites “about,” the numerical value or end-point of a range is intended to include two embodiments: one modified by “about,” and one not modified by “about.” It will be further understood that the end-points of each of the ranges are significant both in relation to the other end-point, and independently of the other end-point. 
     As used herein the terms “the,” “a,” or “an,” mean “at least one,” and should not be limited to “only one” unless explicitly indicated to the contrary. Thus, for example, reference to “a component” includes embodiments having two or more such components unless the context clearly indicates otherwise. 
     In this document, relational terms, such as first and second, top and bottom, and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element. 
     With reference to  FIGS.  1 - 6   , reference numeral  10  generally designates a vehicle  10  that has a body  12  and sensors  14  coupled to the body  12 . The sensors  14  define fields of view  16  that extend in multiple directions from the body  12 . A wash assembly  18  is coupled to the body  12 . The wash assembly  18  is configured to direct fluid to the sensors  14  for cleaning. The wash assembly  18  includes a manifold  20  having an interior  22  divided into pump compartments  24  by internal dividers  26 . The manifold  20  is constructed of an electrically conductive material and includes opposing ground attachments  28 ,  30  coupled to the body  12 . A pump  32  is disposed in each pump compartment  24 . 
     With reference to  FIGS.  1  and  2   , the vehicle  10  is illustrated as an autonomous vehicle  10  that includes the sensors  14  disposed in various locations on the body  12 . Autonomous vehicles  10  generally utilize the sensors  14  and computing devices to operate the vehicle  10  with various levels of interaction from a human driver. The computing devices each generally include a processor, a memory, and other control circuitry. Instructions or routines are stored within the memories and executable by the processors. The computing devices of the vehicle  10  may operate the vehicle  10  in an autonomous mode, a semiautonomous mode, or a non-autonomous mode (e.g., a manual mode). 
     The autonomous mode is one in which each of a propulsion, a breaking, and a steering system of the vehicle  10  is controlled by the computing devices. In the semiautonomous mode, the computing devices control one or two of the propulsion, the breaking, and the steering systems of the vehicle  10 , with a human operator controlling the other system or systems. In the non-autonomous mode, the human operator controls the propulsion, the breaking, and the steering systems of the vehicle  10 . It is contemplated that the vehicle  10  may be a fully autonomous vehicle  10  (e.g., operated without the human operator), a partially autonomous vehicle  10  (e.g., operated with or without the human operator), a manually operated vehicle  10  (e.g., operated with the human operator), or a combination thereof without departing the teachings herein. 
     Referring still to  FIG.  2   , as well  FIG.  3   , the sensors  14  may include a variety of types of sensors  14  for monitoring information around the vehicle  10 . The sensors  14  define the fields of view  16  that extend from the vehicle  10 . Different sensors  14  generally define differently sized (e.g., width, distance from the vehicle  10 , etc.) fields of view  16 . 
     In the illustrated example of  FIG.  2   , the vehicle  10  includes an outer housing  40  coupled to the body  12 , which includes several of the sensors  14 . For example, a LIDAR sensor  42  is coupled to the outer housing  40 . The outer housing  40  also includes various imagers or cameras  44  with image processing circuitry. Additionally, the outer housing  40  may include audio sensors  46 . The vehicle-forward portion of the body  12  also includes multiple sensors  14  including additional LIDAR sensors  42 , additional cameras  44  with image processing circuitry, and radar sensors  48 . The vehicle-rearward portion of the body  12  also includes additional sensors  14 , including LIDAR sensors  42 , radar sensors  48 , cameras  44  with image processing circuitry, and audio sensors  46 . 
     As best illustrated in  FIG.  3   , the various sensors  14  each define the respective fields of view  16 . The fields of view  16  collectively extend in multiple directions from the vehicle  10 , allowing the computing devices to monitor areas surrounding the vehicle  12 . For example, fields of view  16  may extend in a vehicle-forward direction, a vehicle-rearward direction, and in vehicle-side directions. The information detected in the fields of view  16  is generally communicated to the computing devices, which process and utilize the information to control the vehicle  10 . 
     With reference still to  FIGS.  2  and  3   , the sensors  14  may be utilized for adaptive cruise control, breaking, lane departure, parking assist, blind-spot detection, etc. The types of sensors  14  and configuration of the sensors  14  on the body  12  are merely exemplary and not limiting. The vehicle  10  may include additional or alternative configurations of the sensors  14  and additional or alternative types of sensors  14  without departing the teachings herein. 
     The vehicle  10  may be used for personal and/or commercial purposes, such as for ride-providing services (e.g., chauffeuring), transporting, deliveries, ridesharing services, etc. Further, the vehicle  10  may be a sedan, a truck, a van, a sport utility vehicle, a crossover, or other types of vehicles  10  without departing the teachings herein. 
     Referring still to  FIGS.  2  and  3   , each of the sensors  14  is communicatively coupled with the computing devices, which process or analyze information sensed in the fields of view  16  to operate the vehicle  10 . Additionally, each of the sensors  14  is communicatively coupled with an electronic control unit (ECU) or controller  60  associated with a wash system  62  of the vehicle  10 . The controller  60  includes a processor, a memory, and other control circuitry. Instructions or routines are stored in the memory and executable by the processor. The controller  60  generally includes at least one routine directed to receiving and analyzing information from the sensors  14  to determine whether the sensors  14  are dirty or obstructed. The controller  60  may determine that the sensed information is obscured, altered, or otherwise affected by materials on or near the sensors  14 . The controller  60  may then activate the wash system  62  to clean the sensors  14 . 
     Referring again to  FIG.  1   , as well as to  FIG.  4   , the wash system  62  of the vehicle  10  includes the wash assembly  18  communicatively coupled with the controller  60 . In certain aspects, the wash system  62  includes two wash assemblies  18 . Two wash assemblies  18  may be advantageous for housing additional washer fluid on the vehicle  10 , as well as for directing the washer fluid to multiple locations along the body  12  of the vehicle  10 . The wash assemblies  18  may be controlled selectively and independently by the controller  60 . 
     The wash assemblies  18  may be disposed on opposing ends of the vehicle  10 . For example, the vehicle  10  generally includes an engine compartment  70  in a vehicle-forward portion of the body  12 . One of the wash assemblies  18  may be disposed within the engine compartment  70 . Additionally, the body  12  defines wheel wells  72 , and one of the wash assemblies  18  may be coupled to the body  12  proximate to the wheel well  72  in a vehicle-rearward portion of the vehicle  10 . The wash assemblies  18  may be substantially similar, or alternatively may have different configurations based on where the wash assembly  18  is located in the vehicle  10 . In examples where the wash assemblies  18  have different configurations or shapes, the function of the wash assemblies  18  is substantially similar or identical. 
     Referring still to  FIG.  4   , as well as to  FIG.  5   , each wash assembly  18  includes a washer bottle  80  that has a reservoir  82  for storing the washer fluid therein. Each wash assembly  18  includes the manifold  20  in fluid communication with the reservoir  82  of the corresponding washer bottle  80 . The manifold  20  may be included in the washer bottle  80  or may be separate from the washer bottle  80 . Each washer bottle  80  includes an upper level sensor  84  and a lower level sensor  86 . Each of the upper and lower level sensors  84   86  is configured to sense a fluid level of the washer fluid within the washer bottle  80 . For example, when the upper level sensor  84  senses the fluid level, the washer bottle  80  is at a full or substantially full level. When the lower level sensor  86  no longer senses the washer fluid, the washer bottle  80  is at an empty or near empty level. The upper and lower level sensors  84 ,  86  are configured to communicate with the controller  60 . The controller  60  is configured to monitor the fluid level within the reservoirs  82 . When the controller  60  determines the fluid level is low, the controller  60  may generate an alert to be communicated to the human operator, a passenger, or another user. The alert may indicate the fluid level is low and should be refilled. 
     Referring still to  FIG.  5   , as well as  FIG.  6   , the manifold  20  defines the interior  22 , which is divided into a pump cavity  100  and a fluid cavity  102  by a dividing wall  104 . The dividing wall  104  may generally separate the pump cavity  100  from the fluid cavity  102 ; however, the pump cavity  100  and the fluid cavity  102  are generally in fluid communication with one another. In such configurations, the dividing wall  104  defines openings allowing this fluid communication. The pump cavity  100  is further separated into the multiple pump compartments  110 - 118 , which are separated by the internal dividers  26  and collectively referred to herein as the pump compartments  24 . Each pump  32  may be entirely or substantially separated and isolated from an adjacent pump  32  by the respective internal divider  26 . Each pump  32  is, therefore, generally isolated within the manifold  20  by an outer structure of the manifold  20 , the dividing wall  104 , and the internal dividers  26 . In the illustrated configuration of  FIG.  6   , the manifold  20  includes five pumps  120 - 128 , collectively referred to herein as the pumps  32 . 
     The fluid cavity  102  is further separated into chambers  140 - 146 , collectively referred to herein as chambers  148 , which are separated from one another by inner dividers  152 . The inner dividers  152  are generally aligned with the internal dividers  26  on opposing sides of the dividing wall  104 . In this way, the pump compartments  24  are generally aligned with the chambers  148 . The inner dividers  152  substantially separate each chamber  148  from the adjacent chambers  148 . However, each inner divider  152  may define an opening or channel  154 , allowing the chambers  148  to be in fluid communication with one another. 
     Each wash assembly  18  includes the pumps  32  disposed within the manifold  20 . In the illustrated configuration of  FIG.  6   , the manifold  20  houses the five pumps  120 - 128  arranged in a linear configuration within the manifold  20  but may have other configurations without departing from the teachings herein. The manifold  20  includes a same number of impellers  160 - 168  as pumps  32 . The impellers  160 - 168 , collectively referred to herein as impellers  170 , are arranged in the chambers  140 - 146 , respectively. Each chamber  148  houses one impeller  170 , and each impeller  170  is associated with a single pump  32 . In various aspects, the impellers  170  are configured to extend through the dividing wall  104  to engage the respective pumps  32 . 
     Referring still to  FIG.  6   , the impellers  170  and the pumps  32  are each in communication with controller  60  and may be selectively and independently activated to direct the washer fluid to the select location on the vehicle  10 . The manifold  20  defines a single inlet  180  for receiving the washer fluid from the washer bottle  80 . The activated impeller  170  or impellers  170  may assist in drawing the washer fluid into the fluid cavity  102  and into the chambers  148  with the active impellers  170 . The washer fluid may flow through the inlet  180 , through some of all of the chambers  148 , and through the channels  154  in the inner dividers  152  to reach the select chamber  150  with the activated impeller  170 . The activated impeller  170  may drive, guide, or push the washer fluid to the corresponding pump  32  in the adjacent pump compartment  24 . The activated pump  32  then directs the washer fluid through a corresponding outlet  182  to a selected location within the vehicle  10 . 
     Each pump  32  is associated with a respective outlet  182 . In this way, the wash assembly  18  includes the single inlet  180 , and five outlets  184 - 192 , each of which is associated with a single pump  32 . The outlets  184 - 192 , collectively referred to herein as the outlets  182 , are in fluid communication with tubing that extends to the select location (e.g., the sensors  14 , a windshield fluid system  200 , etc.) on the vehicle  10  for cleaning. 
     Each of the pumps  32  and the impellers  170  may generate noise when activated. The noise generated by the wash assembly  18 , particularly the wash assembly  18  located proximate to the rear wheel well  72  ( FIG.  1   ), may adversely affect the experience of the passengers within the vehicle  10 . The configuration and construction of the manifold  20  may reduce or minimize the noise that is generated by the wash assembly  18  by substantially containing the noise within the manifold  20 . 
     Additionally, at least the pumps  32  may generate electromagnetic fields (EMF) when activated. The EMF may adversely affect the function of the upper and lower level sensors  84 ,  86 . If the upper and lower level sensors  84 ,  86  are affected by the EMF, the upper and lower level sensors  84 ,  86  may become ineffective or have reduced accuracy in sensing and communicating the fluid level within the washer bottle  80 . With less or inaccurate sensing of the fluid washer level, the wash system  62  may not indicate to the user when the washer fluid is at the empty or near empty level. Further, if the washer fluid reaches the empty level, the sensors  14  ( FIG.  2   ) may not be cleaned. The configuration and construction of the manifold  20  may reduce, minimize, or prevent that EMF from affecting or interfering with the upper and lower level sensors  84 ,  86  by shielding and isolating the pumps  32 . 
     Referring still to  FIG.  6   , the materials of the manifold  20  also assist with shielding the EMF and noise. In various aspects, the manifold  20  and each component thereof (e.g. the internal dividers  26 , the inner dividers  152 , and the dividing wall  104 ) are constructed of the electrically conductive material. The electrically conductive material may be, for example, conductive plastic. The manifold  20  constructed of the electrically conductive materials may be more efficient as additional shielding components or materials may not be utilized in the wash assembly  18 . 
     In various examples, the manifold  20  is constructed of treated conductive nano-materials. In certain aspects, the treated conductive nano-materials are carbon nanostructures. The carbon nanostructures may be produced through a chemical vapor deposition process that produces flakes of carbon rich with cross-linked carbon nanotubes that if processed with high shear processing, branch out and spread into the three dimensional shapes and take up a larger volume of space. The carbon nano-structure flakes are approximately 50 μm in size. Through a first dispersion process the carbon nanostructure flakes generally break into smaller fragments under low shear in a matrix, and in a second dispersion process, high shear leads to long and branched carbon nanotubes. The carbon nanostructures are electrically conductive material and at least partially shield the EMF. 
     As the manifold  20  is constructed of electrically conductive material, the manifold  20  is self-grounded to the body  12  of the vehicle  10  with ground bolts  210 ,  212 . As best illustrated in  FIG.  6   , the manifold  20  includes the ground attachments  28 ,  30  on opposing sides of the manifold  20 . The ground attachments  28 ,  30  are generally configured as tabs or flanges that extend outward in opposing directions and are constructed of the electrically conductive material. In the illustrated configuration of  FIG.  6   , the first ground attachment  28  extends proximate to the first pump compartment  110  and the inlet  180 , while the opposing ground attachment  30  extends outwardly from proximate to the fifth pump compartment  118 . 
     A power connector  220  such as, for example, a six-way connector, is coupled to the manifold  20 . Generally, as illustrated in  FIG.  6   , the power connector  220  is coupled to a central location between the two ground attachments  28 ,  30 . The power connector  220  is operably coupled to each pump  32  to provide power to each pump  32 . Additionally, the power connector  220  also provides a common ground or common ground point for the electrically conductive manifold  20 . The manifold  20  is constructed of the electrically conductive material to shield the EMF. 
     With reference again to  FIGS.  1 - 6   , the manifold  20  is in fluid communication with the washer bottle  80 . The manifold  20  includes the inlet  180 , which may be approximately 12 mm in diameter, which is in fluid communication with the reservoir  82  of the washer bottle  80 . When at least one of the pumps  32  is activated, the washer fluid is directed from the washer bottle  80 , through the inlet  180 , and into the fluid cavity  102 . The fluid cavity  102  holds and contains the washer fluid to feed into the pumps  32  when at least one of the pumps  32  is activated. The pumps  32  and the impellers  170  are each in communication with the controller  60 . The controller  60  may selectively and independently operate each impeller  170  and each pump  32 . 
     In various examples, the controller  60  may activate selected impellers  170  and pumps  32  based on the end location for the washer fluid or based on the cleaning to be performed. For example, when one of the sensors  14  is determined to be obstructed or dirty, which may be determined by the controller  60  analyzing the sensed information, the controller  60  may activate the select impeller  170  and pump  32  to direct the washer fluid to the obscured sensor  14 . Additionally, when a windshield  230  of the vehicle  10  is to be cleaned, the controller  60  may activate the select impeller  170  and pump  32  to direct the washer fluid to the windshield fluid system  200 . Once activated, the impellers  170  may assist in drawing the fluid into the fluid cavity  102  and pushing the fluid to the corresponding pump  32 . The pumps  32  are configured to direct the washer fluid through the corresponding outlet  182  and to the sensors  14  or windshield fluid system  200 . 
     The manifold  20  houses the pumps  32  such that each pump  32  is separated and substantially isolated with shield portions of the manifold  20 , which substantially contain the EMF from escaping the manifold  20 . The manifold  20  is constructed of the electrically conductive material, which assists in shielding the EMF and is grounded to the body  12  of the vehicle  10  with ground bolts  210 ,  212  on both sides of the manifold  20  at the ground attachments  28 ,  30 . The power connector  220  provides the common ground for the manifold  20 , as well as power to each of the pumps  32 . 
     Use of the present device may provide for a variety of advantages. The manifold  20  has the single inlet  180  in fluid communication with the interior  22 , which may decrease leak potential when directing the washer fluid into the manifold  20 . Further, the manifold  20  has the single power connector  220 , which may provide poka-yoke connections. Additionally, the manifold  20  is constructed of the electrically conductive material to protect against and shield the EMF. In this way, no additional shields may be added to the manifold  20  or the wash assembly  18 . Further, the manifold  20  is grounded to the vehicle  10  with the ground bolts  210 ,  212  coupled to the body  12  of the vehicle  10 . Also, the manifold  20  may be located anywhere in the vehicle  10 , including the wheel well  72  and the engine compartment  70 . In this way, the manifold  20  allows for increased flexibility in the location of the wash assembly  18  due to the reduced noise level from the manifold  20 . Additionally, the manifold  20  may have an increased size, as the pumps  32  are included in the manifold  20  rather than the washer bottle  80  components. This configuration may provide increased fluid volume in the wash assembly  18 , which is advantageous for autonomous vehicle  10  use with the various sensors  14 . Further, use of the manifold  20  may improve the durability of the wash assembly  18  and increase efficiency in the manufacturing process. Additional benefits or advantages may be realized and/or achieved. 
     According to various examples, a vehicle includes a body. Sensors are coupled to the body and define fields of view that extend in multiple directions from the body. A wash assembly is coupled to the body. The wash assembly is configured to direct fluid to the sensors for cleaning. The wash assembly includes a manifold having an interior divided into pump compartments by internal dividers. The manifold is constructed of an electrically conductive material and includes opposing ground attachments coupled to the body. A pump is disposed in each pump compartment. Examples of the present disclosure may include one or a combination of the following features:
         the manifold is constructed of carbon nanostructures;   the wash assembly includes a power connector coupled to the manifold and configured to provide power to each of the pumps;   the ground attachments are coupled to the body via ground bolts;   the wash assembly further includes a lower level sensor and a upper level sensor;   the lower level sensor and the upper level sensor are configured to sense a level of fluid within a washer bottle;   the pumps generate electromagnetic fields when activated;   the manifold is configured to shield the electromagnetic fields to reduce interference of the electromagnetic fields with the lower level sensor and the upper level sensor;   the body defines a wheel well; and/or   the manifold is coupled to the body proximate to the wheel well.       

     According to various examples, a vehicle wash system includes a manifold having pump compartments separated by dividers. The manifold is constructed of an electrically conductive material to shield electromagnetic fields. A pump is disposed within each compartment and configured to generate the electromagnetic fields when activated. A power connector is coupled to the manifold. The power connector is configured to power each pump and is a common ground for the manifold. An upper level sensor is proximate to the manifold. A lower level sensor is proximate to the manifold. The upper level sensor and the lower level sensor are configured to sense fluid level in a washer bottle. Examples of the present disclosure may include one or a combination of the following features:
         the manifold defines an outlet associated with each pump;   each outlet directs the fluid to a separate location;   the separate locations include sensors and a windshield fluid system;   the manifold includes ground attachments on opposing sides of the manifold;   the ground attachments are configured to be grounded to a vehicle body with ground bolts;   the manifold is constructed of treated conductive nano-materials;   the manifold is constructed of carbon nanostructures;   the manifold defines a fluid cavity in fluid communication with an inlet to receive the fluid from the washer bottle;   an impeller is coupled to each pump; and/or   each impeller is disposed in the fluid cavity to guide the fluid from the fluid cavity to the corresponding pump.       

     According to various examples, a wash assembly for a vehicle includes a manifold defining an interior. The manifold includes a dividing wall separating the interior into a fluid cavity and a pump cavity, first dividers separating the pump cavity into pump compartments, and second dividers separating the fluid cavity into chambers. Each second divider defines an opening for fluidly coupling the chambers. Each chamber aligns with one of the pump compartments. A pump is disposed within each pump compartment. An impeller is disposed within each chamber. Each impeller extends through the dividing wall to engage one of the pumps, respectively. Examples of the present disclosure may include one or a combination of the following features:
         the manifold is constructed of carbon nanostructures configured to shield at least one of electromagnetic fields and noise generated by at least one of the pumps and the impellers;   the manifold includes ground attachments extending from opposing sides thereof;   a power connector coupled to the manifold;   the power connector is configured to provide power to each pump and a common ground point; and/or   the manifold defines an outlet in fluid communication with each pump and a single inlet.       

     For purposes of this disclosure, the term “coupled” (in all of its forms, couple, coupling, coupled, etc.) generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature or may be removable or releasable in nature unless otherwise stated. 
     Further, where appropriate, functions described herein can be performed in one or more of: hardware, software, firmware, digital components, or analog components. For example, one or more application specific integrated circuits (ASICs) can be programmed to carry out one or more of the systems and procedures described herein. Certain terms are used throughout the description and claims to refer to particular system components. As one skilled in the art will appreciate, components may be referred to by different names. This document does not intend to distinguish between components that differ in name, but not function. 
     It should be noted that the sensor examples discussed above might include computer hardware, software, firmware, or any combination thereof to perform at least a portion of their functions. For example, a sensor may include computer code configured to be executed in one or more processors and may include hardware logic/electrical circuitry controlled by the computer code. These example devices are provided herein for purposes of illustration and are not intended to be limiting. Examples of the present disclosure may be implemented in further types of devices, as would be known to persons skilled in the relevant art(s). 
     It is also important to note that the construction and arrangement of the elements of the invention as shown in the exemplary examples is illustrative only. Although only a few examples of the present innovations have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes, and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited. For example, elements shown as integrally formed may be constructed of multiple parts or elements shown as multiple parts may be integrally formed, the operation of the interfaces may be reversed or otherwise varied, the length or width of the structures and/or members or connectors or other elements of the system may be varied, the nature or number of adjustment positions provided between the elements may be varied. It should be noted that the elements and/or assemblies of the system might be constructed from any of a wide variety of materials that provide sufficient strength or durability, in any of a wide variety of colors, textures, and combinations. Accordingly, all such modifications are intended to be included within the scope of the present innovations. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the desired and other exemplary examples without departing from the spirit of the present innovations.
