Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention is directed to a lottery display sign that can be wirelessly interconnected into a network for controlling a display and is adjustable to not only accommodate different static graphic images and illuminated numerical displays of potential payoffs and variable related information but to also automatically adjust luminance contrast of the sign to its environment. 
         [0003]    2. Description of Related Art 
         [0004]    Display signs that have been used in casinos and in retail outlets for providing information relating to game play or a lottery payoff are known. With regards to slot machines utilized in a casino, an electronic adjustment of the potential jackpot is frequently utilized to inform the player of the value of a possible win and to create excitement on a casino floor to encourage players to invest their money based on an illuminated potential jackpot. 
         [0005]    Illuminated signs are also utilized to display potential lottery winnings, for example as sponsored by various states and made available in various commercial outlets such as convenience stores. As with the casino slot machines, there is a necessity to change the value of a potential lottery jackpot based on the total prior value of the lottery tickets that are purchased. 
         [0006]    LED signs composed in a seven segment array are known to be able to provide a value from 1-9 and 0 by selective activation of the individual segments. 
         [0007]    In order to provide illuminated signs of a compact configuration, there have been attempts to provide strips of LEDs to permit a compact edge lit signage. 
         [0008]    In such an environment there is still a need to provide a compact lightweight adjustable illuminated lottery sign that can maximize the advertisement capabilities in a compact configuration that will support additional functional features while accurately enabling an updating of the potential jackpot to the consumer. Such an illuminated sign should be easily manufactured and capable of various forms of display. 
       SUMMARY OF THE INVENTION 
       [0009]    It is desirable that the lottery signs not only be accurate to prevent any disputes on the value of the tickets sold, but also to be relatively compact so that the lottery signs can be conveniently placed adjacent both cash registers and/or displayed in the window of commercial establishments. 
         [0010]    It is desirable to further provide additional information in an adjacent display area that can direct the consumer&#39;s attention to the current lottery value. Additionally, there are frequently different daily, weekly and other types of lottery games that can be made available. 
         [0011]    It would be an advantage to enable a lottery sign to be able to accommodate different lottery games on the same display sign. It is also desirable to draw attention to such auxiliary information by illuminating the signage while also permitting the signage to be changed without requiring an entirely new illuminated sign. 
         [0012]    The present invention provides an illuminated sign having a compact housing unit of a lightweight and thin configuration. A light illuminating unit, such as a replaceable backlight module, can be mounted on the housing unit to emit light across at least a first side of the housing unit and to permit a relatively easy replacement of any lighting elements that may fail. 
         [0013]    A transparent backlight panel can extend across the first side of the housing unit and be optically connected to emitted light from a light emitting unit. The light emitting unit can be removably mounted across one edge of the transparent backlight panel. A reflection section, for example, having an array of reflection sites, is positioned directly against the transparent backlight panel to operatively engage the optical paths of the light rays emitted from the light emitting unit in order to redirect the light from the light emitting unit outward through the transparent backlight panel to a viewer. A replaceable light transmissive sign or graphic member is configured to be backlit by the light emitting unit, such as a strip of light emitting diodes, and to be mounted easily onto and removed from the housing unit. 
         [0014]    One or more light emitting arrays can additionally provide visible indicia to the user, for example, indicating the numerical value of a lottery jackpot. The replaceable sign member can be configured to accommodate a frontal display of any visible indicia from one or more light emitting arrays mounted in the housing unit. 
         [0015]    Additionally, a modified form of the present invention can also incorporate a scrolling message sign unit wherein a visible message can be scrolled across the illuminated sign to provide additional information or to attract attention by displaying sports scores or topic news events. The replaceable sign member would also be configured to accommodate the display of this scrolling information while presenting static images at appropriate adjacent locations on the display sign. 
         [0016]    The replaceable sign member can be secured by an over center bias panel unit that is mounted by a hinge connector across a surface of the housing unit. Accordingly, different replaceable sign members, for example on flexible plastic sheets, can be mounted on the housing unit and appropriately secured flat against the transparent backlight panel by the same removable backlight module. 
         [0017]    A light sensor assembly for measuring ambient light in the environment of a location of the illuminated sign can measure and provide an output signal to automatically adjust an output of light from the light emitting unit to provide a predetermined contrast with the ambient light. A control unit processor can set drive voltages to activate the light emitting unit based on the output signals and predetermined values and associated with the processor. 
         [0018]    The light sensor output can be processed to automatically provide a control of the brightness of the backlight panel and/or also an array of light emitting diodes (LEDs) to provide numerical values of a jackpot. For example, a day and night level of luminous flux for daylight and for nighttime can be provided by an automatic activation by the control unit processor mounted in the sign. 
         [0019]    Alternatively, a more precise control of multiple levels of luminous flux can be provided by storing a correlation between measured Lux by a photo sensor with a specific drive voltage for both an edge strip of LEDs to a backlight panel and one or more light emitting arrays for providing visible indicia such as numerical digital values. 
         [0020]    The illuminated sign can include a wireless transceiver or a wired transceiver for receiving electronic data, including values of the lottery jackpot for updating the display of the numerical value under the control of a control processor at the headquarters of the Lottery. The transceiver can also receive communication data for driving indicia across the scrolling message sign unit. 
         [0021]    Thus, a wireless update of jackpot sums, an on, off and/or a panel flashing, a brightening or dimming of digits, a light pattern of chasing borders around a digital display and even stock quotes on an EMC message board can be provided by a wireless link, as examples that can be centrally controlled to provide uniform information at each retail outlet. 
         [0022]    Alternatively, an EPROM can store operation data which can be either manually updated or could be updated using an RJ 11 RS 232 port on the illuminated sign housing. 
         [0023]    A rear side over center bias panel mounted by a hinge connector is also capable of mounting a replaceable graphic sign member on the rear side of the sign, for example, when the front of the sign is mounted within an exterior display window. 
         [0024]    The housing unit can include a pair of rotatable stand members that facilitate a stable support of the illuminated sign on a horizontal support surface while permitting the stand members to be retracted when the illuminated sign is hung from a wall or in a display window. 
         [0025]    A user input for varying the controls of the illuminated sign and the indicia to be displayed can also be incorporated as either a wireless input unit or a wired input unit for entering data into the processor. 
         [0026]    A backlight module for lighting the removable sign member or graphic light transmissive cover can include a holder member mounting an elongated panel member in an over center bias arrangement to cause the panel member to be either open or closed for engaging the replaceable sign member or graphic cover member. A support member can be attached to a holder member to position an array of light emitting diodes (LEDs) at a position offset from a back frame member. The light emitting diodes can be mounted on an elongated strip which in turn is attached to the support member. 
         [0027]    A transparent backlight panel or panels can be connected to the holder member beneath the array of LEDs to optically couple with the emitted light and to conduct light within the backlight panel. The backlight panel member can secure the removable graphic cover or sign member against the backlight panel to illuminate the replaceable sign or graphic cover, whereby a light module for lighting a removable graphic cover or sign is provided.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0037]    Reference will now be made in detail to the preferred embodiments of the invention which set forth the best modes contemplated to carry out the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be obvious to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present invention. 
         [0038]    Referring to  FIG. 1 , an illuminated sign  2  is shown in a perspective view and has been subjectively configured to provide viewer information on the total sums that can be won for respectively a Mega Lottery game and a Power Lotto game. A removable light transmissible graphic panel  4  of plastic has the terms “Mega Lottery” and “Power Lotto” printed on the rear surface of the flexible graphic panel  4  and then covered, by printing, with a diffusion ink to distribute the LED light in a uniform manner. As can be appreciated, additional information such as symbols or icons can also be applied such as dollar symbols and an appropriate legend indicating, for example, the value of any numbers illuminated on the respective light emitting array  6  and light emitting array  8  can be placed beneath or above the respective light emitting arrays such as the term “Million.” 
         [0039]    Preferably, the graphic panel  4  is a single flexible sheet of plastic material of 0.1 cm or less in thickness, with a relatively clear rectangular panel or window segment sections permitting a display of the respective numbers by the light emitting arrays  6  and  8 . The clear plastic panels  5  can be further coated on the back side of the graphic panel  4  with a color such as red  5 , so that the lottery amounts that are provided on the respective light emitting arrays  6  and  8  can provide a more dramatic effect on a viewer. 
         [0040]    The light emitting rays can be from a source of light emitting diodes (LEDs) formed into a seven segment array configuration to represent numbers 1 through 9 and 0, depending on which segment of LEDs are driven, as known in the art. Decimal places can also be illuminated. Various images and/or designs can be provided at a rear surface of the graphic panel  4  by printing or silkscreening to provide desired indicia and symbols while still being transmissive to a backlight to illuminate information on the graphic panel  4  surrounding the respective light emitting arrays  6  and  8 . 
         [0041]    Reference can be made to an exploded view of  FIG. 3  where a rectangular back frame  10  is formed, for example, from a metal sheet. A rear surface panel  12  is connected to the back frame  10  to form the main components of the housing unit  9 . Respective light emitting arrays  6  and  8  with individual light emitting array segments can be mounted respectively on circuit boards with appropriate drive circuitry that can be connected to and controlled by a CPU control board  14  that is also mounted on the rear surface  12 . 
         [0042]    A wireless transceiver  16  in the form of a module is also mounted on the rear surface  12  of the housing unit. As known in radio technology, a transceiver is a device that can comprise both a transmitter and a receiver. Alternatively, a separate transmitter and a separate receiver could also be utilized. The wireless transceiver  16  enables radio communication to provide data to the CPU control board  14  such as the lottery jackpot sum which can be frequently updated on a daily basis by a central computer at the lottery control center, based on the number of people purchasing lottery tickets. The wireless transmission to the illuminated sign  2  enables freedom in locating the sign in a retail establishment. 
         [0043]    A pair of rotatable support stands  18 , each of a U-shaped metal plate are mounted at the bottom of the back frame  10  and can be rotated to be in line and parallel with the back frame  10  when the illuminated sign  2  is hung or suspended from a wall.  FIGS. 1 and 2  show the support stands  18  rotated 90°, relative to the housing unit  9 , to provide a stand alone support for the illuminated sign on a horizontal support surface. 
         [0044]    Movable triangular hook members  20  can be mounted at the top of a mounting top bar  26  to facilitate hanging the illuminated sign  2 , for example by a chain in the window of an establishment selling lottery tickets. A photo sensor  22  is mounted on the mounting top bar  26 , for example, positioned on the top of the back frame  10  or at another appropriate location. See  FIGS. 3 and 4 . The photo sensor  22  is to monitor ambient light that contacts the front of the illuminated sign  2 . As will be subsequently described, the photo sensor  22  and photo sensor circuit  23  can provide an output voltage signal to the CPU control board  14 . 
         [0045]    The back surface of rear surface member  12  can support additional advertisement sheets and can use a plurality of snap frame panels  56  extending about the rear perimeter as shown in  FIG. 3 . Accordingly, when the illuminated sign  2  is displayed in an exterior display window to attract lottery users, the internal rear facing portion of the illuminated sign can also display additional appropriate advertisements. 
         [0046]    A backlight module  24  includes the mounting top bar  26  that can be screwed onto the top of the back frame  10 . As can be seen, the movable triangular hook members  20  and the photo sensor  22  can be appropriately mounted to the mounting top bar member  26 . The mounting top part  26  can be formed by bending a metal sheet and an edge light holder  28 , formed from an aluminum extrusion, can be fastened to the front surface of the mounting top bar member  26  by appropriate screws that can also secure the movable triangular hook members  20  and on one side the photo sensor housing  22 . 
         [0047]    The edge light holder  28  is formed by an aluminum extrusion process that includes a channel  30  with an overhanging lip that can mount an aluminum extruded snap frame panel  32  as shown in  FIGS. 4 and 5 . The edge light holder  28  also includes a cantilevered ledge member  34  that was integrally formed during the extrusion so that the underside surface of the ledge member  34  could support an adhesive strip  36  that would secure a light emitting unit  38  such as an LED edge lit strip of an aligned array of LEDs on a supporting printed circuit board structure. 
         [0048]    A spring member  40  provides an over center force bias on the snap frame panel  32  so that it is biased open as shown in  FIG. 5  or biased closed as shown in  FIG. 4 . A camming edge of the snap frame panel  32  would be forced against the outer surface of the spring member  40  to create the over centered locations. The spring member  40  could be mechanical or have other configurations to facilitate the bias over centered positions. 
         [0049]    An adhesive strip  42  is also attached to the edge light holder  28  to secure a reflecting backlight film sheet  44 . The backlight film sheet  44  is formed from a thin acrylic sheet with a reflective coating. 
         [0050]      FIG. 3  discloses a transparent relatively thick plastic backlight panel  46  can be split into right and left hand segments to prevent light leakage between panel segments. Alternatively a large single piece backlight panel can be used. The top edge of the backlight panel is connected to LED light sources on the LED edge lip strip  38 . The light is transmitted downward through the edge of the transparent backlight panel  46  to reflect from the appropriate parallel internal surfaces of the transparent backlight panel  46  by a dispersion section, such as an array of dispersion dots  45  printed on the rear surface of backlight panel  46  for reflecting any contact of the light from LED edge lip strip  38  outward through the front of the transparent backlight panel  46 . Light reflected backward will be reflected back through the array of dots by the reflective coating on the film sheet  44 . The reflected light travels through the graphic panel  4  which is held, as shown in  FIG. 4 , by the snap frame panel  32  against the front surface of the transparent backlight panel  46 . Note, as shown in  FIG. 3 , lightweight spacers  19  such as Styrofoam blocks of various sizes can be inserted within the housing unit  9  to provide locational support for the transparent backlight panel  46 . 
         [0051]    Referring to  FIG. 6 , a schematic diagram of a photo sensor  22  and a photo sensor circuit  23  and its relationship with the CPU control board or control unit  14  is disclosed. Basically, the photo sensor  22  is excited by ambient light, such as the sun, and a series of resistors and capacitors enable a voltage signal to be applied to an anode side of an amplifier  48  where an amplified signal is generated to provide a voltage signal input into the CPU control board  14  representative of ambient light contacting the front of the illuminated sign  2 . 
         [0052]    In one embodiment, the CPU control board  14  can be programmed with software and/or firmware, including an EPROM, with an algorithm or as disclosed in  FIG. 6 , with a lookup table (LUT)  50  that permits the CPU control board or control unit  14  to match the ambient light voltage signal with a corresponding voltage output to drive the LED edge strip  38  and the light arrays  6  and  8  to provide an appropriate contrast illumination for the illuminated sign  2  in response to the ambient light. If a small voltage signal is produced, indicating a relatively dark ambient condition, the control unit  14  can then select from the lookup table  50  an appropriate voltage to provide an appropriate contrast to optimize the use of the voltage level power and the desired appearance of the illuminated sign  2  with backlighting. 
         [0053]    In another embodiment, if the ambient light is relatively bright, greater than 3000 Lux, a larger voltage signal would cause the LED edge strip  38  to be turned off to conserve power, conversely, light below 3000 Lux will light the panel to provide an appropriate contrast to attract the viewers. 
         [0054]    Referring to  FIG. 7 , a schematic overall control diagram is disclosed wherein the transceiver  16  can wirelessly receive a data signal indicative, for example, of drive information for disclosing respective numerical values of each jackpot as disclosed, for example, in  FIGS. 1 and 2 . As can be appreciated, data information may be sent to each retail store from a control center of the lottery headquarters and connected to the illuminated sign by wire or broadcast by a radio transmitter wirelessly to the transceiver  16  to control the display elements of the illuminated sign  2   
         [0055]    The control unit  14  can be connected to a conventional AC electrical source and a transformer can provide a DC output. For our purpose, the combination provides a power source  52  which can drive the light emitting unit or LED edge lip strip  38  to backlight the backlight module  24  to illuminate the graphic panel  4 . Additionally, the control unit  14  can drive appropriate drive circuits associated with each of the light emitting arrays  6  and  8  to provide an appropriate numerical value for respectively the Mega Lottery and/or the Power Lotto from the power source  52 . Alternatively, a manual input device  54  such as a keyboard or computer port connection can permit an operator to input drive signals including numerical values for the individual jackpots, directly into the control unit  14 . 
         [0056]    Note, appropriate power connections, universal ports, dip switches and/or on/off power switches can be mounted adjacent the light module  24 . A power transformer, not shown, can convert 110 volt AC to 12 volt DC to power the LEDs. A dip switch can adjust the reception frequency of the transceiver  16  to prevent interference with any adjacent sign. 
         [0057]      FIG. 7  also provides for a scrolling message sign  56  shown, for example, in the second embodiment of  FIG. 2 . As can be appreciated, again a transceiver  16  or a manual input  54  can provide information data to the control unit  14  that permits the composition of a scrolling message and a driving of a strip array of LEDs in either a black and white configuration or a multiple color configuration to provide information to attract a viewer&#39;s interest. For example, sports scores or topical events can be utilized to draw the user&#39;s attention to the illuminated sign  2  and thereby transfer the viewer&#39;s interest to that of potential winnings that could occur by purchasing an appropriate lotto ticket. An example of a type of scrolling message sign can be seen in U.S. Pat. No. 6,271,814, incorporated herein by reference. 
         [0058]    Alternatively, the control unit  14  can implement a further embodiment of the present invention with the same photo sensor  22  and photo sensor circuit  23  of  FIG. 6  based on only a measurement of greater than &gt;3000 Lux or a measurement of less than &lt;3000 Lux for two levels of ambient light that can drive alternative auto sensor modes in the environment of  FIG. 7  as follows:

         [0059]    In Auto Mode A the LED edge strip  38  for backlighting the panel is either ON or OFF while the light emitting arrays  6  and  8  for providing numerical digital values of jackpots are either Bright or Dim. That is, Bright=approximately 12 mA while Dim=approximately 5 mA. 
         [0060]    Thus, when the Lux value is lower than 3000 there is an activation to a night mode which activates the backlighting of the panel only on the Night setting. This Auto Mode A conserves the life of the LEDs on the edge strip  38  on the assumption that the panel will be adequately lit by reflection of ambient light by the array of reflection dots  45  on the back panel  46  and the reflective coating on the backlight film sheet  44 . 
         [0061]    In Auto Mode A, the digital light emitting arrays  6  and  8  will be activated to automatically be driven to a Bright state above 1000 Lux and will stay on Bright until a Dim state is provided below 1000 Lux. 
         [0062]    In the Auto Mode B the sensor  22  will activate the panel lighting on at all time and keep it on at all times. Again, as in the Auto Mode A, the digital light emitting arrays  6  and  8  will be activated to automatically be driven to a Bright state above 1000 Lux until the sensor  22  senses lower than 1000 Lux and switches to Dim. 
         [0063]    Possible manual switch settings for Day and Night as default settings when the Auto Sensor is disabled are as follows:

         [0146]    In summary, a relatively economical thin and lightweight illuminated sign  2  is provided that can be both hung on a wall or in a display window or alternatively, supported on a horizontal support space with a capacity to provide a backlight module  24  for lighting a removable graphic panel  4 . A pair of LED arrays  6 ,  8  is capable of providing numerical information such as the value of lottery games. The light module  24  is mounted on a back frame  10  and can suspend different graphic panels  4  on an exterior surface of the illuminated sign depending on the lottery games being offered. 
         [0147]    Referring to  FIG. 8 , as shown in step  1 , a backlight module  24  can be assembled with a thin reflective backlight film sheet  44  pressed against a vertical rear surface of a transparent plastic backlight panel  46 . As shown in step  2 , the backlight module  24  can then be assembled onto the frame of housing unit  9  with the respective lighting arrays  6  and  8 . The transparent panels  5  can be clear or have an attractive color such as red, to be aligned over the respective light emitting arrays  6  and  8 . In the final assembly step  3 , replaceable sign member or graphic panel  4  is disclosed as being arranged to slide downward across the face of the transparent backlight panel  46  or pair of panels  46  with the vertical side edges and bottom edges of the frame  10  holding the graphic panel  4  in place. 
         [0148]    The top snap frame panel  32  captures a top horizontal edge of the graphic panel  4 , so that the graphic panel  4  can be replaced with another graphic panel to change both the basic display symbols and meet the requirements of any particular lottery game. In  FIG. 8 , the illuminated sign  2  is disclosed with the rotatable stands  18  positioned in a retracted mode for suspending the illuminated sign  2  in a window or hanging the illuminated sign  2  on a wall. When the pair of rotatable stands  18  are rotated at 90° from the position shown in  FIG. 8 , the illuminated sign  2  can be supported on a horizontal surface. 
         [0149]    As can be appreciated, the illuminated sign  2  can be easily repaired to replace defective light emitting arrays  6  and  8  along with regards to any burnout LEDs on the edge light strip  38 . Thus, an economical and versatile lightweight illuminated sign  2  is provided that can automatically adjust the contrast of the illumination of the sign  2  relative to any ambient light environment. 
         [0150]    Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the amended claims, the invention may be practiced other than as specifically described herein.
