s eye apparatus 330 and a second batter &# 39 ; s eye apparatus 340 ( and / or a third batter &# 39 ; s eye apparatus 350 ) may be used or provided to create a system 360 of batter &# 39 ; s eye apparatus with a collective and / or combined wider or larger visual backdrop area ( e . g ., from a home plate and / or batter &# 39 ; s perspective ). for example , as shown in these figures , first , second , and third batter &# 39 ; s eye apparatus 330 / 340 / 350 may be provided to create the system 360 or a larger batter &# 39 ; s eye or backdrop ( e . g ., from the perspective of the batter or home plate ). it should be appreciated , however , that while first , second , and third three batter &# 39 ; s eye apparatus 330 / 340 / 350 are shown in fig8 - 14 , any number of the batter &# 39 ; s eye apparatus ( such as the five batter &# 39 ; s eye apparatus shown in fig9 ) may be provided or utilized as desired , to create system 360 . in various embodiments , second batter &# 39 ; s eye apparatus 340 ( and / or third batter &# 39 ; s eye apparatus 350 ) are provided in an overlapping and / or staggered position relative to first batter &# 39 ; s eye apparatus 330 ( e . g ., from a plan and front view ). as shown in the figures , first batter &# 39 ; s eye apparatus 330 may be provided in one location , and second and / or third batter &# 39 ; s eye apparatus 340 / 350 may be provided adjacent but partially behind first batter &# 39 ; s eye 330 relative to a batter or home plate , or further from a batter or home plate . in various embodiments , second and / or third batter &# 39 ; s eye apparatus 340 / 350 are set back from first batter &# 39 ; s eye apparatus 330 . such a staggered , overlapped or setback position may allow the panel of each apparatus to move between the panels of the other batter &# 39 ; s eye apparatus of system 330 . in various embodiments , however , the overlap between the panels of first , second , and / or third batter &# 39 ; s eye apparatus 330 / 340 / 350 of system 360 helps allow , as illustrated in fig1 and 14 , movement of the panels , and wind and / or airflow 370 between the panels of first , second , and / or third batter &# 39 ; s eye apparatus 330 / 340 / 350 of system 360 , while reducing the chances or period of time that a visual light seam or hole will develop in the batter &# 39 ; s eye system 360 or backdrop , from the batter &# 39 ; s or home plate perspective that may reduce the effectiveness of system 360 ( e . g ., by making it more difficult for the batter to see a pitched ball , or otherwise create a distraction for the batter ). for example , and referring to fig1 , the panels of first , second , and / or third batter &# 39 ; s eye apparatus 330 / 340 / 350 may be able to adjust , move , re - shape , re - orient , etc ., from first illustrative panel position and orientation 110 a , to a second illustration panel position and orientation 110 b , to a third illustrative panel position and orientation , as well as any multitude of other panel positions , orientations , and combinations thereof , to help allow apparatus 330 / 340 / 350 / and / or system 360 spill or otherwise adjust to wind and airflow 370 . the adjustment , movement , re - shaping and / or re - orientation helps the apparatus and system to tolerate wind loads and / or design maximum gusts . it can also reduce the complexity and cost of a support structure for the batter &# 39 ; s eye and the batter &# 39 ; s eye system as a whole . as utilized herein , the terms “ approximately ,” “ about ,” “ substantially ”, and similar terms are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains . it should be understood by those of skill in the art who review this disclosure that these terms are intended to allow a description of certain features described and claimed without restricting the scope of these features to the precise numerical ranges provided . accordingly , these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed are considered to be within the scope of the invention as recited in the appended claims . it should be noted that references to relative positions ( e . g ., “ top ” and “ bottom ”) in this description are merely used to identify various elements as are oriented in the figures . it should be recognized that the orientation of particular components may vary greatly depending on the application in which they are used . for the purpose of this disclosure , the term “ coupled ” means the joining of two members directly or indirectly to one another . such joining may be stationary in nature or moveable in nature . such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate members being attached to one another . such joining may be permanent in nature or may be removable or releasable in nature . it is also important to note that the construction and arrangement of the system , methods , and devices as shown in the various examples of embodiments is illustrative only . although only a few embodiments 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 show 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 connector or other elements of the system may be varied , the nature or number of adjustment positions provided between the elements may be varied ( e . g . by variations in the number of engagement slots or size of the engagement slots or type of engagement ). the order or sequence of any process or method steps may be varied or re - sequenced according to alternative embodiments . other substitutions , modifications , changes and omissions may be made in the design , operating conditions and arrangement of the various examples of embodiments without departing from the spirit or scope of the present inventions . while this invention has been described in conjunction with the examples of embodiments outlined above , various alternatives , modifications , variations , improvements and / or substantial equivalents , whether known or that are or may be presently foreseen , may become apparent to those having at least ordinary skill in the art . accordingly , the examples of embodiments of the invention , as set forth above , are intended to be illustrative , not limiting . various changes may be made without departing from the spirit or scope of the invention . therefore , the invention is intended to embrace all known or earlier developed alternatives , modifications , variations , improvements and / or substantial equivalents . the technical effects and technical problems in the specification are exemplary and are not limiting . it should be noted that the embodiments described in the specification may have other technical effects and can solve other technical problems .
