DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(16) Referring now to the drawings and more particularly to FIG. 1, there is illustrated an exemplary static billboard sign modification or retrofit kit 2, which is constructed in accordance with the present invention. The retrofit kit 2 is for in field use to convert a static billboard or poster panel sign, which carries printed images such as those generated via a printing process, into a dynamic programmable full height sectional sign assembly for roadside or building signage use. In this regard, the electronic sign may be programmed to display content that is optimal for the hour of the day or for the day of the week by the simple electronic transmission of a desired image to the sign formed by the application of the modification kit 2 to an existing static billboard sign. For the reasons provided herein, the upgrading an existing static billboard sign into a dynamic programmable electronic sign is therefore highly desired.

(17) Considering now the exemplary modification or retrofit kit 2 in greater detail with reference to FIG. 1, the modification kit 2 generally includes a frame section kit 3, a power kit 6, and an installation kit 8. In an exemplary embodiment the modification kit 2 is self-contained although it is possible that portions of modification kit 2 may be provided separately to a site at which an existing static billboard sign is to be converted to an electronic display. It should be noted that the modification kit 2 may contain some or all of the elements depicted in FIG. 1 and may contain additional elements not depicted. Each of the component elements of the modification kit 2 will now be considered in greater detail.

(18) Sectional Sign Assemblies

(19) The frame section kit 3, generally includes at least one sectional sign assembly 4 having a predetermined number N of frame sections, such as a frame section 10, and a predetermined number n of LED display modules, such as a LED display module 12. The number N of frame sections 10 collectively define an array width for the electronic sign. In this regard, it should be understood that the modification kit 2 may contain one or more frame sections, where the exact number N of frame sections 10 is or will be determined by the width of an existing static billboard or signage mounting structure that will be modified using the modification kit 2. In a similar manner, the predetermined number n of LED display modules is or will be determined by the predetermined number N of frame sections 10 which are provided in the modification kit 2 as will be explained hereinafter in greater detail.

(20) The static billboard modification kit 2 is configured in a customized manner determined by the location of the existing static billboard being converted or retrofitted, including the accessibility of that location by conventional transportation entities. In this regard, in a first embodiment of the modification kit 2, the frame sections 10 and LED display modules 12 are packaged on separate pallets and shipped to the on-site location either together or separately.

(21) In a second embodiment, some of the LED display modules 12 are pre-installed in frame sections 10 so that this installation processes is accomplished in a factory setting as opposed to an in-field setting making conversion and installation easier, faster and more efficient. In this embodiment, some of the LED display modules 12 are shipped uninstalled allowing for their in-filed installation as dictated by the overall signage configuration.

(22) In a third embodiment, all of the LED display modules 12 are pre-installed in their respective frame sections 10 allowing fully loaded frame sections to be shipped and installed when they arrive at an on-site location. In short, field installation in this embodiment does not include the task of installing individual ones of the LED display modules into their respective frame sections 10.

(23) In a fourth embodiment, as will be explained hereinafter in greater detail, frame sections 10 are shipped in a pre-wired configuration to facilitate ease in coupling the frame sections 10 to an available source of AC power.

(24) In summary then, the manner in which the modification kit 2 is configured and shipped to an on-site location is dependent upon the location of the static billboard sign being converted, installation considerations as well as the ease and availability of various shipping methods depending upon the size of the sign being converted.

(25) Led Display Modules

(26) The LED display modules of the present invention, such as the LED display module 12; if being installed in an outdoor environment is weatherized. In this regard, each LED display module 12 is highly water resistant and requires little, if any, water protection that would be otherwise provided by the frame sections 10. Each individual one of the LED display modules 12 can be weatherized through the use of one or more of waterproof gaskets, potting adhesives such as epoxies, and over molded portions.

(27) Power Kit

(28) As already noted, in certain embodiments of the present invention, frame sections, such as the frame section 10 are shipped pre-wired to take advantage of factory pre-assembly processes. In other situations, depending upon whether the static billboard was or was not provided with electrical power, it may be more advantageous to provide the modification kit 2 with a power kit 6 as best seen in FIG. 1. In this case the power kit 6, forming part of the modification kit 2 generally includes one or more AC/DC power/data hubs, indicated generally at 14, one or more power and data enclosures 16, and sufficient AC wiring 18 for routing power from the main power enclosures 16 to the individual hubs 14. In an exemplary embodiment as best seen in FIG. 3, each main power and data enclosure 16 couples to external AC line power and to an external data link. The AC wiring 18 can be for coupling data and AC power from the main power and data enclosure 16 to the individual hubs 14. There can be a hub 14 for each frame section 10. Each hub 14 receives AC power and data from the main enclosure 16. Each hub 14 is provided for rectifying the AC power and for delivering the rectified DC power and the data to a single frame section 10.

(29) Other designs are possible. For example, in an alternative embodiment power may be rectified at the main power and data enclosure 16. Then each hub 14 can be for receiving DC power and data to be delivered to its respective frame section 10.

(30) In another embodiment the circuitry of each hub 14 is integrated into a sectional assembly frame section 10. Then AC line power in this configuration can then be coupled directly to each sectional assembly frame section 10.

(31) Installation Kit

(32) Depending upon the number of frame sections 10 to be utilized in a conversion process or retrofit project, the modification kit 2 may further include an installation kit 8. The installation kit 8 helps in field conversion by facilitating coupling frame sections together for mounting to a pre-existing static sign mounting structure. In this regard, as best seen in FIG. 1, each installation kit 8 forming part of the modification kit 2 generally includes a set of mounting brackets, such as a mounting bracket 20, as best seen in FIGS. 9 and 9A and lifting and datum hardware 22 as best seen in FIG. 7. Mounting brackets 20 are provided for coupling each frame section 10 to an existing signage mounting structure S. In addition to mechanical coupling and support, mounting brackets 20 provide compensation for non-planarity of an existing signage structure S. Lifting and datum hardware 22 provides a way of aligning the frame sections with respect to each other and for facilitating lifting one section 10 or a group of sections 10 up and onto the existing signage mounting structure as best seen in FIGS. 9 and 9A.

(33) As noted earlier, variations for the modification kit 2 are possible. For example, a hub 14 may be integrated into each frame section 10 rather than having hub 14 as a separate portion of a modification kit 2. Mounting brackets 20 or lifting and datum hardware 22 or portions thereof may also be integrated into each of frame sections 10. Additionally, modification kit 2 may include other hardware and tools.

(34) As noted earlier, by application of the modification kit 2 to an existing signage structure S, a static poster panel sign for carrying printed images is modified into a dynamic electronic sign 24, which hereinafter will also be referred to as a converted sign 24. In this regard, FIG. 2 depicts a simplified front view of a first embodiment of such an electronic sign 24 illustrating for simplicity only the sectional sign assemblies 4. In this embodiment, the retrofit kit 2 utilized on the billboard sign S included ten sectional sign assemblies 4, where each sectional sign assembly includes or is configured for holding an array of forty-eight LED display modules 12 and where each individual LED display module 12 is received within a bay 11. In this exemplary embodiment each LED display module 12 includes a square array of emissive LED pixels that is approximately 14 inches by 14 inches in size. Each sectional sign assembly 4 is four LED display modules 12 wide and twelve LED display modules 12 in height. The width dimension W of the sign 24 is indicated by the illustrated X-axis and the height dimension H of the sign is illustrated by the Z-axis.

(35) According to the illustrated embodiment of FIG. 2, each sectional sign assembly 4 defines the full illuminated height H of the sign 24, but only a fractional portion of the full illuminated width W of the sign 24. In this arrangement therefore, a plurality of aligned sectional sign assemblies 4, in a side-by-side arrangement, define the full illuminated width W of sign 24. In this illustrated embodiment, the full illuminated height H of the sign 24 is about 14 feet and the full illuminated width W of the sign 24 is about 46.7 feet. Of course the dimensions W and H are exemplary and illustrative of one large embodiment for converted sign 24.

(36) FIG. 3 is a simplified rear view of the first embodiment converted electronic sign 24. According to this illustrative embodiment, a previous static billboard or poster panel sign structure S included two vertical poles 26 coupled to two horizontal beams 28 which, during the retrofitting process, are utilized with the installation kit 8 for supporting the other component parts of the modification kit 2, namely the sectional sign assemblies 4 and power kit 6 for forming the converted sign 24. In this first embodiment of the converted sign 24, each of the sectional assemblies 4 are mounted to two or more horizontal beams 28 via mounting brackets 20, as best seen in FIGS. 3A, 9 and 9A.

(37) Also depicted in FIG. 3 is the main power and data enclosure 16 of power kit 6, which is shown mounted to one of the vertical poles 26. The main power and data enclosure 16 receives the primary AC power service and data lines and couples the AC power and data to each of the AC/DC power/data hubs 14 via wiring 18. In this embodiment there is one power and data hub 14 for each sectional assembly 4. Each power and data hub 14 rectifies the AC power coupled from enclosure 16 into low voltage DC power, and provides both the low voltage DC power and data to each of the LED display modules 12 in the sectional sign assembly 4 via a wiring harness or power routing system 32. It should be understood by those skilled in the art that in an alternative embodiment, there can be provided a wireless link between the enclosure 16 and each of the hubs 14 to enable the data to be delivered or coupled wirelessly from enclosure 16 to each of the hubs 14.

(38) FIG. 3A depicts a portion of FIG. 3 in greater detail to illustrate various features of the modification kit 2. In this regard, FIG. 3A illustrates only a portion of two sectional sign assemblies 4 showing how the individual mounting brackets 20 couple the sectional sign assembly 4 to the horizontal beam 28. FIG. 3A also depicted that each sectional sign assembly 4 is provided with a rear access doors 34 which allows removal and replacement of the LED display modules 12 from the rear side of converted electronic sign 24. It should therefore be understood by those skilled in the art, that in this first embodiment the individual LED display modules 12 mounted within the sectional sign assemblies 4 can be removed and replaced from either the front side (depicted in FIG. 2) or the rear side (FIG. 3) of sign 24.

(39) Considering the modification kit 2 in still greater detail with reference to FIG. 4, a single sectional assembly 4 is shown in a layered elevation view. The layering is indicated by the designators LS1 (layer step 1) and LS2 (layer step 2). The portion of the sectional assembly 4 that is to the left of LS1 includes 20 LED modules that are installed in sectional assembly 4. The portion of the sectional assembly 4 that is between LS1 and LS2 includes bays 11 which do not contain LED display modules 12. Each bay 11 is configured to receive one LED display module 12. The bays 11 are in part defined by a front sheet metal layer 46. The portion of the sectional sign assembly 4 that is to the right of LS2 is shown with the front sheet metal layer 46 removed for illustrating a rear sheet metal layer 48 and the rear access doors 34.

(40) Sectional sign assembly 4 has its major or height dimension defined along the vertical Z-axis as best seen in FIG. 4. The sectional sign assembly 4 also has its intermediate or width dimension defined along the horizontal X-axis, and its minor or depth dimension defined along the horizontal Y-axis. In an exemplary embodiment the height dimension can be in a range of about 8 feet to about 14 feet. In an exemplary embodiment the width dimension can be in a range of about 2 feet to about 5 feet. In an exemplary embodiment the depth dimension is less than about 1 foot or more preferably less than about 6 inches.

(41) Considering now the AC/DC power and data hub 14 in greater detail with reference to FIGS. 4, 4A and 4B, the power and data hub 14 receives AC power and data via wiring 18 which is provided between the main power and data enclosure 16 and each hub 14. The power and data hub 14 rectifies the supplied AC power to low voltage DC power and then couples the low voltage DC power and data, via two wiring harnesses 32 to the individual bays 11. The two wiring harnesses 32 are prewired in the sectional sign assemblies 4. As best seen in FIG. 4, each wiring harness 32 has an input end 36 coupled to hub 14 and a plurality of output ends 38 that are each disposed in one of the bays 11. Each wiring harness 32 is routed vertically along vertical axis Z or along the length dimension of the sectional sign assembly 4. Individual output ends 38 emerge and branch out from wiring harness 32 and each individual output end 38 extends generally horizontally along axis X into each bay 11.

(42) Considering the wiring harness 32 in still greater detail with reference to FIGS. 4, 4A and 4B, the sectional sign assembly 4 includes a framework of outer vertical beams 40, outer horizontal beams 42, and internal vertical beams 44. The framework of beams 40, 42, 44 provides mechanical strength of sectional assembly 4. Also, some internal vertical beams 44 can facilitate the vertical routing of wiring hamesses 32 which follow along two such internal vertical beams 44 that pass between pairs of bays 11 as best seen in FIG. 4B.

(43) FIG. 4A depicts a cross-section view of sectional sign assembly 4 taken through section A-A of FIG. 4. The axis Y is along a depth axis relative to sectional assembly 4. Sectional assembly 4 includes outer vertical beams 40 and internal vertical beams 44. The framework provided by beams 40 and 44 support front sheeting 46 and rear sheeting 48. Attached to the outer vertical beams 40 are channels 50 which facilitate mounting of sectional assembly 4 to horizontal beams 28 (see FIGS. 3 and 3A). Two LED display modules 12 are shown about to be installed into bays 11 (left side of FIG. 4A) and two LED modules 12 are shown already installed into bays 11. Access doors 34 are shown open that allow rear removal and replacement of LED display modules 12. In the design as depicted the LED modules 12 can be installed from a front or rear surface of sectional assembly 4.

(44) FIG. 4B depicts a cross-section view taken through section B-B of FIG. 4. Sectional assembly 4 includes outer vertical beams 40, internal vertical beams 44, front sheeting 46, rear sheeting 48, vertical channels 50, and LED modules 12 (two waiting to be installed and two installed).

(45) Two of the vertical internal beams 44 provide support for wiring harnesses 32 passing vertically (along the Z-axis) between pairs of bays 11. The support can be in the form of a C-channel, metal conduit, or a series of holes for using cable ties just to mention a few examples. For each wiring harness 32 there are pairs of output ends 38 that extend along opposing directions into adjacent bays 11. Each output end 38 includes a connector 52 for coupling harness 32 to an LED module 12 assembled into its associated bay 11.

(46) In an exemplary embodiment the main structural components of sectional assembly 4 are formed from aluminum in order to minimize weight. The beams 40, 42, and 44 can all be formed from extruded and/or rolled aluminum. The sheeting 46 and 48 can be aluminum sheet metal. In other embodiments some or all of the beams 40, 42, and 44 can be formed from extruded steel, other metals, composite materials or other high strength materials. In yet other embodiments the sheeting 46 and/or sheeting 48 can be formed from other materials such as passivated stainless steel, epoxy coated steel or plastic to mention a few examples.

(47) Considering now the LED display module 12 and the bay 11 in which it is received in greater detail with reference to FIG. 5, an interface 54 is provided between each LED display module 12 and its respective bay 11. The interface 54 between LED display module 12 and bay 11 provides alignment, latching, a power connection, and a data connection. More specifically, the interface 54 includes alignment feature 56 such as complementary pin and openings that engage to align LED display module 12 to bay 11. The alignment feature 56 can be implemented as a pin on LED display module 12 that engages an opening on bay 11 or a pin in bay 11 that engages an opening on LED display module 12. Other types of alignment features are possible, such as a ball and notch alignment combination (not shown).

(48) In the illustrative embodiment as best seen in FIG. 5, the LED display module 12 includes a latch mechanism 58 that extends horizontally along the X-axis to engage openings in bay 11 with latches 60. In an alternative embodiment bay 11 may include a latch to engage openings (not shown) in LED display module 12.

(49) A portion of wiring harness 32 is shown that extends vertically along the Z-axis between a pair of bays 11 from which two output ends 38 branch along approximately opposing directions to connectors 52. In an exemplary embodiment wiring harness 32 is a power and data harness. Connector 52 is a power and data connector 52 that enables simultaneous power and data connection from harness 32 to LED module 12 by pressing connector 52 onto a complementary connector 52′ (under connector 52) that is integrated into LED module 12. In an exemplary embodiment the connector pair 52 and 52′ is a pin and socket pair. One of the connector pair 52 and 52′ is a connector pin array (52 or 52′) and the other is a corresponding connector socket array (52 or 52′) for receiving the connector pin array. Each connector pin (not shown) either transfers data or power or is a ground connection between harness 32 and LED module 12.

(50) FIG. 6 depicts an illustrative method of retrofitting a static billboard to a digital sign. Some details have been left out for illustrative simplicity. Some steps may not be necessary or may alter in their sequence depending on a particular embodiment.

(51) The retrofit method begins with an existing static billboard sign. According to step 62 the billboard panel is removed and horizontal beams 28 are exposed (See FIG. 3). Poles 26 supporting horizontal beams 28 are the main structural support and poles 26 together with beams 28 define the existing signage mounting structure.

(52) According to step 64 a weatherized LED module 12 is installed into each bay 11. Step 64 may not be necessary if the LED modules 12 are factory preinstalled before the retrofit process. Alternatively LED modules 12 can be installed into bays 11 as a later procedure that follows any of steps 66-78 of FIG. 6.

(53) According to step 66 a power hub 14 is attached to each sectional assembly 4. As an alternative method, power hub 4 can be attached as a later step after any of steps 68-76. Input end 36 of wiring harness 32 is electrically coupled to power hub 4.

(54) According to step 68 mechanical couplers 22 are attached to groups of two or more sectional assemblies 4. This is illustrated in FIG. 7 which shows a mechanical coupler 22 that is attached to at least three sectional assemblies 4. In an exemplary embodiment the mechanical coupler 22 is attached to four such sectional assemblies 4 to allow four sectional assemblies 4 to be aligned and hoisted at the same time.

(55) Mechanical coupler 22 includes constraining features 69 and 70 to constrain motion of sectional assemblies 4 with respect to the X and Y axes. Each constraining feature 69 includes a pin extending from coupler 22 that engages an opening in the top horizontal beam 42 of a sectional assembly 4 to provide a datum function. Each constraining feature 70 is a bolt attachment having a dual function of constraining motion and also coupling coupler 22 to sectional assembly 4. Coupler 22 includes a threaded rod 71 that allows the position of pairs of sectional assemblies 4 to be adjusted along the X-axis. Some of the constraining features 70 provide constraint in Z and Y but allow for motion along X to allow action of the threaded rod 71.

(56) Also providing motion constraint are datum plates 73 that constrain motion between sectional assemblies 4 with respect to the Z-axis as well as constraining rotation about the Y-axis. Datum plates 73 can be part of installation kit 8 (FIG. 1) and are preferably installed prior to lifting groups of sectional assemblies onto horizontal beams 28.

(57) Thus groups of sectional assemblies 4 are placed in alignment through the attachment of mechanical coupler 22. Mechanical coupler 22 also includes lifting features 72 that allow hooks of a crane to lift mechanical coupler 22 thereby lifting an aligned group of sectional assemblies 4 in one lifting or hoisting step.

(58) According to step 74 sectional assemblies 4 (or groups thereof using mechanical couplers 22) are sequentially lifted and coupled to horizontal support members 28 (see FIG. 3). This includes alignment of all the sectional assemblies 4 with respect to each other which can be accomplished via mechanical couplers and/or other means.

(59) According to step 76 a main utility box 16 is attached to pole 26 (see FIG. 3). According to step 78 the main utility box 16 is electrically coupled to each of the hubs 14 utilizing wiring 18. As indicated earlier other orderings of steps are possible. For example, attaching the main utility box 16 can be performed earlier in the process such as between steps 62 and 64.

(60) One difficulty with retrofitting signs is a lack of planarity of the supporting structure defined by poles 26 and horizontal beams 28. To address this difficulty the method of FIG. 8 is utilized. The method of FIG. 8 involves the apparatus of claim 9 and can be incorporated into the method depicted by FIG. 6. It is here being described separately for simplicity and better illustration.

(61) FIG. 9 depicts sectional assembly 4 attached to horizontal beam 28 via mounting bracket 20. Mounting bracket 20 is configured to provide a secure planar orientation of sectional assembly 4 even when horizontal beams 28 are not perfectly parallel or defining a perfect line. Thus if beams 28 are non-linear (e.g., curved) or skewed relative to one another the mounting bracket 20 can compensate to a reasonable degree.

(62) FIG. 9A is a detail view taken from FIG. 9 to illustrate certain functional components of mounting bracket 20. Mounting bracket 20 includes first plate 80, adjustable spacer 82, and second plate 84. First plate 80 is attached to channel 50 via channel nuts 86. First plate 80 includes a slot 88 that captures an upper portion of beam 28 to support sectional assembly 4 upon beam 28. The slot 88 has a depth dimension along the Y-axis that allows for positional adjustments of sectional assembly 4 with along the depth dimension Y. Adjustable spacer 82 is utilized to adjust the planar orientation of sectional assembly 4. Finally the second plate 84 is utilized to lock or restrain the position of first plate 80 with respect to beam 28 once adjustments have been made. Thus the mounting bracket has functions that include support, dimensional compensation, dimensional adjustment, and mechanical locking.

(63) Referring back to FIG. 8 a method of mounting one or more sectional assemblies 4 to horizontal beams 28 is depicted. Referring back to FIG. 3 horizontal beams can include an upper beam 28U and lower beam 28L. The description of FIG. 8 will refer to the assembly of a sectional assembly 4 to beams 28 but it is to be understood that an exemplary embodiment concerns assembling more than one sectional assembly 4 at a time by employing mechanical coupler 22. In an exemplary embodiment mechanical coupler 22 attaches to four such sectional assemblies 4 which are mounted to the horizontal beams as a mechanically coupled group of sectional assemblies 4.

(64) According to step 90 lower first plates 80 corresponding to the lower beam 28L are assembled to sectional assemblies 4. As shown in FIG. 3A there can be two mounting brackets 20 (which each include a first plate 80) attached to each sectional assembly 4. According to step 92 a sectional assembly 4 (or group of sectional assemblies) is hoisted or raised.

(65) According to step 94 the lower first plates 80 are configured relative t lower beam 28L whereby slot 88 captures the top of beam 28L (see FIG. 9A). According to step 96 the upper first plates 80 are then attached to couple the sectional assembly 4 to upper beam 28U. Thus upper and lower beams 28 are captured by slots 88 which allow for planarity adjustments.

(66) According to step 98 the spacers 82 are adjusted to properly orient sectional assembly 4. As of step 98 all of the sectional assemblies 4 may be already assembled to beams 28 to allow for planarity adjustments of all the sectional assemblies at once. Alternatively the adjustment can be made on one sectional assembly (or mechanically coupled groups thereof) at step 98.

(67) After step 98 the second plates 84 are tightened into place which locks the planarity adjustment of sectional assembly 4. As indicated by the dashed arrows in FIG. 8, there are variations possible in terms of the sequence of steps depending on the preference of the assembly crews. Planarity of the sectional assemblies can be adjusted and fixed when they are all assembled to beams 28 or they can be adjusted and fixed one at a time. In yet another embodiment a coarse adjustment can be performed each time a sectional assembly is raised and then a fine adjustment can be performed after all are assembled to beams 28. Although FIG. 8 describes mounting a sectional assembly 4 to two horizontal beams 28 it is to be understood that an existing signage mounting structure will typically have two or more such horizontal beams 28. Some existing mounting structures will have 3 or 4 such horizontal beams 28. In this case step 96 will include mounting the first plates 80 for mounting to all of the horizontal beams 28 that are above the lower horizontal beam 28L.

(68) FIG. 10 depicts a simplified front view of an embodiment of an electronic sign 102. Sign 102 results when a static billboard sign is retrofitted with an embodiment of kit 2. Sign 102 differs from sign 24 of FIG. 2 in that it is a smaller sign that utilizes a combination of four sectional assemblies 104 that are four LED modules wide and one sectional assembly 106 that is three LED modules wide. Each of the sectional assemblies 104 are four modules wide in X and 9 modules high in Z. The sectional assembly 106 is three modules wide in X and 9 modules wide in height. The illuminated portion of sign 102 has a height H of about 10.5 feet as measured along the Z-axis and a width W of about 21 feet as measured along the X-axis.

(69) Internal design characteristics of the sectional assemblies 104 can be similar to the earlier-described sectional assemblies 4 with respect to features such as routing of the wiring harness 32, power and data hubs 14, and the interface 54 between each LED module 12 and its respective receiving bay 11. In that regard sectional assemblies 104 and 106 are each exemplary embodiments of sectional assemblies 4 of FIG. 1. The sectional assembly 106 would have one or two wiring hamesses 32 and a hub 14 configured for supporting an array of 27 LED modules 12. As can be seen, sectional assemblies 4 can take on a range of form factors of LED modules to support retrofitting a wide variety of static billboard supports.

(70) While the present disclosure has described a process for mounting one or more sectional sign assemblies to the horizontal supports of an existing sign structure, the mounting of such a sign section assembly is not limited to one particular mounting structure. According to the present invention, “an existing sign structure” or “an existing signage mounting structure” can include portions of or one or more of vertical beams, horizontal beams, diagonal beams, sheet metal panels, a sheet metal panelized system, a structural steel grid, a lattice structure of any appropriate ridged material, such as steel, structural foam, and plastic for example, a spaceframe, a billboard structure, architectural cladding, sign cabinet framing, a framed walling, a concrete walling, a planar surface. These are but a few of the surfaces that may be included as part of an existing signage mounting structure. Thus, there is no intention of limiting the scope of the type of surfaces and structures that can be modified to become a dynamic electronic sign or billboard.
