Abstract:
The present invention is directed to a system and method which allows a display to have a dimension significantly greater than the actual dimension of the matching utility box or traditional utility box device faceplate. Thus, by making the size of the faceplate independent from the size of the matching utility box or traditional utility box faceplate, larger displays are possible which allows for larger size lettering and pictures and also allows for increased electronics within the display itself. In one embodiment, faceplate displays having double, triple or even quad-gang size can be positioned over a single-gang utility box thereby increasing the space for electronics as well as increasing the amount of (or size of) displayable material.

     TECHNICAL FIELD 
       [0002]    This disclosure relates to infrastructure devices and more particularly to faceplate displays for such devices that are not limited in size by the confines of the infrastructure device. 
       BACKGROUND OF THE INVENTION 
       [0003]    Infrastructure devices are those devices that are mounted to a premises in such as manner as to be permanent or at least not easily removed therefrom. One aspect of an infrastructure device is that it is connected, at least electrically, to wiring affixed to the premises structure. Another aspect of an infrastructure device is that it is connected via wired or wireless communications to devices that are themselves connected electrically to the premises electricity delivery infrastructure. A light switch is one form of an infrastructure device. An electrical outlet is another form of such a device. A TV, radio, security system, surveillance system, premise-based communication system, or game box is yet another form of such device. Other infrastructure devices can be, for example, a wide variety of sensors/systems such as are obvious (e.g., light switches, plugs, thermostats, inline power boxes, etc) but also non-obvious sensors/systems such as light sensors, temperature sensors, internet access systems, WAN system, LAN systems, RF systems, display systems, power sensors, power supply systems, schedulers, clocks, audio/video systems, intercom systems, telephone systems, HVAC systems, television, radio, cameras, proximity sensors, occupancy sensors, GPS, entertainment systems, safety monitoring systems, security systems, fire monitoring systems, surveillance systems, messaging systems, alert and alarm systems, medical monitoring systems, data monitoring systems, data control systems, access monitoring systems, access control systems, legacy remote control systems (e.g., TVs, radios, lighting), media reader systems, identification systems, humidity sensors, barometric pressure sensors, weight sensors, traffic pattern sensors, power quality sensors, operating costs, power factor sensors, meters, storage systems, distributed generation systems, UPS systems, battery monitoring systems, priority systems, inertia sensors, glass break sensors, flood sensors, vibration sensors, smoke sensors, carbon dioxide sensors, carbon monoxide sensors, ultrasound sensors, infra-red sensors, microwave sensors, radiation sensors, bacteria sensors, disease sensors, poison sensors, germ sensors, toxic material sensors, air quality sensors, laser sensors, load sensors, load control systems, etc. 
         [0004]    A common trait of infrastructure devices is that they are mounted in boxes, usually called utility boxes, permanently (for all practical purposes) affixed to the premises. Utility boxes come in various sizes with the smallest size (single gang) having a front opening of roughly 2½ inches wide and 4 inches tall. Utility boxes typically grow larger in the width direction. Thus a two-gang utility box has the same height (4 inches) but a width of 5 inches, with a triple-gang box having a width of 7½ inches, etc. 
         [0005]    Utility device covers, called faceplates, are sized to fit the width of the box. Thus faceplates come in single-gang, double-gang, triple-gang, etc. sizes. All of these sizes have a similar height but vary in width. In situations such as discussed in one or more of the above-identified patent applications where it is desired to have the cover of a utility device act as an information display, the size limitations of a single-gang and possibly even a double-gang box limits the size of the displayed information. This then reduces the amount of information that can be displayed and/or reduces the size of the letters or images on the display. As a result, the distance away from the display a person can be and still be able to read it properly is also reduced. 
         [0006]    In addition to the display size limitations imposed on a faceplate, for example, by a single-gang box, there is also a limitation as to the amount of electronics that can be positioned within the faceplate. For complex faceplate displays that can handle a number of different functions, the need for electronic footprint space is critical. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    The present invention is directed to a system and method which allows a display to have a dimension significantly greater than the actual dimension of the matching utility box or traditional utility box device faceplate. Thus, by making the size of the faceplate independent from the size of the matching utility box or traditional utility box faceplate, larger displays are possible which allows for larger size lettering and pictures and also allows for increased electronics within the display itself. In one embodiment, faceplate displays having double, triple or even quad-gang size can be positioned over a single-gang utility box thereby increasing the space for electronics as well as increasing the amount of (or size of) displayable material. 
         [0008]    The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0016]      FIG. 1  is a schematic drawing showing one embodiment of the expanded faceplate, such as faceplate  20 , employed in an infrastructure electrical system. System  10  as shown in  FIG. 1  illustrates wall  100  that is part of the premises structure. Wall  100  is supported by studs  11  and has a cut-away portion  101  that shows utility box  12 - 1  fastened permanently to a stud  11 . Electrical cables, such as cables  13  are connected to box  12 - 1  and are terminated within the box in any well-known manner. Box  12 - 1  has screw holes  14  positioned to accept a faceplate (not shown in conjunction with box  12 - 1 ). Utility box  12 - 1  can accept any number of utility switches, plugs, or other devices. Also, shown within box  12 - 1  are contacts  15 - 1  and  15 - 2  which are positioned to provide electrical communication with a faceplate, if necessary. Utility box  12 - 1  is positioned in a location where one would typically expect to find a light switch. 
         [0017]    Also shown in  FIG. 1  is a second utility box  12 - 2  positioned in a location where one would typically expect to see a power outlet (electrical socket). Box  12 - 2  has connected thereto faceplate  20  which in this embodiment is a four-gang sized faceplate covering single-gang utility box  12 - 2 . 
         [0018]      FIG. 2  shows one embodiment  20  of expanded faceplate  200  for use with single, double, triple, quad, etc. utility boxes. Holes  25  are used to fasten the faceplate to the desired utility box by using traditional screws. Of course, any other method of fastening the faceplate to the box can be employed, including, for example, snap or spring loaded connectors, magnets, etc. In the embodiment shown, one portion of the faceplate has an opening  22  to cover a traditional electrical socket  23 , or the socket can be part of the faceplate. When the socket is part of the faceplate, portions of the socket could extend into the utility box, such as into utility box  12 - 2 ,  FIG. 1 . If the socket is extended into the box, then screw holes  25 A and  25 B are used in conjunction with holes  14  in the mating box to position the faceplate. The faceplate then extends to the right of the utility box by one gang width and extends to the left of the utility box by two gang widths, as shown in  FIG. 1 . Faceplate  200  has display  21 , keypad  24 , as well as internal electronics  26 , and can have any thickness T desired. 
         [0019]    Note that the exact width or height of the faceplate is not critical but should for esthetic reasons fit into the decor of the premise to which it is to be used. Thus, the size (both height and width) should be such as to be pleasing to the eye and not make the faceplate appear as though it is foreign to the environment. In most cases, this would dictate that the faceplate width be made to appear to be a multiple (such as two, three, four, five, six, etc) of a standard single-gang faceplate. Thus, while the faceplate need not be exactly a gang box width multiple, it should be close enough to such a multiple so as to not appear to be out of place. Note also that the faceplate display could, subject to any element positioned on the faceplate that would need to fit into a utility box, extend left or right (or up/down) of the box by any amount. Also note that traditional faceplates are marginally larger than the utility box. In the discussion herein, the faceplate is significantly larger. In this context, ‘significantly’ means that to the user&#39;s eye, it appears to be wider (taller) than a typical gang box by at least one inch and in most cases, by at least two inches. 
         [0020]    Note that using the concepts of the invention, commonly available LCD panels normally destined for small notebook computers or portable DVD players and that have a traditional 3×4 or 6×9 aspect ratio, can be used as a faceplate of desired, even though such devices do not fit the standard light switch cover height parameters. 
         [0021]    The front surface of the faceplate would have a display or other user-visible operational elements distributed across substantially all of the front surface, regardless of the faceplate size. The term ‘substantially all’ does not imply that every portion of the faceplate must have some visible display but rather that there are no large gaps or obviously missing elements as there would be, for example, if one where to place a traditional two-gang faceplate over a single-gang utility box. In such a situation, the area of the faceplate in front of the ‘missing’ gang-box would be blank, or substantially blank, because there could be no display device mounted in the ‘missing’ box. In some cases the ‘substantially all’ test would be satisfied if the faceplate contained a gap for a device mounted in a gang-box. For example, assume a triple-gang width faceplate display were to be used with a switch mounted in a single-gang utility box. The triple-gang faceplate could have an opening therein (either in a center position, or left or right of center) to accept a utility box mounted switch. 
         [0022]    Note that in most applications, the triple-gang faceplate would likely be one piece that can be attached on via connectors on the faceplate back-side to the actual ‘in-box” switching module using a two piece design (the faceplate and the switching module). A preferred approach then would be to allow the switching module to be connected to the faceplate in a “centered”, “left”, and “right” side orientation. In other words, the faceplate could be centered on the box or offset to the left or right side of the box (or up or down) according to how the faceplate might best look on the wall so as to provide better placement than where the box is actually located. In such a situation, the backside of the faceplate would have a sophisticated connection system (not shown) to cover reasonable switch and faceplate mounting combinations. 
         [0023]      FIG. 3  shows one embodiment  30  of faceplate  200  having display  31  with soft keys  32 . This display and keys can be programmed under the control of an internal or external processor. 
         [0024]      FIG. 4  shows one embodiment  40  of an expanded faceplate, such as faceplate  400 , for use with a single or double utility box. Faceplate  400  also has display  41  for allowing a user to use the utility system to perform a wide variety of functions. Holes  45  are used, as discussed above, to mount the faceplate to the utility box or to a device already mounted in the utility box. Electronic circuitry  42  can be, if desired, contained within faceplate  400 . 
         [0025]      FIGS. 7A through 7D  shown that the faceplate can be any size or shape desired to work with any size utility box and to fit the décor or the physical limitations of the premises. Thus, a “tall” (higher than it is wide) faceplate ( 70 ,  FIG. 7A ) can be used where horizontal space is not practical. A wide faceplate ( 71 ,  FIG. 7B ) can be used when vertical size is not desired.  FIG. 7C  shows a round faceplate  72  and  FIG. 7D  shows a triangular faceplate  73 . Any geometry and/or size can utilize the concepts discussed herein. 
         [0026]      FIG. 5  shows a view of back surface  401  of a faceplate illustrating one embodiment of how electrical contact is made to the premises utility system. In his embodiment, contacts  51 - 1  to  51 - 4  are used for mating with contacts, such as contacts  15 - 1 ,  15 - 2  ( FIG. 1 ) located in the mated utility box. Communication between the faceplate and the utility box (or devices within the utility box) can be by electrical contact, as shown or wirelessly by RF, optics or any other method. Wireless connection would facilitate offset faceplate mounting as discussed above. 
         [0027]      FIG. 6  shows system  60  in which two faceplates are mated side by side to form a double width faceplate. Note that while each of these faceplates is shown as a single-gang width faceplate, they can be any width or height desired and any number of widths (or heights) can be added as desired. Multiple faceplates can thus be combined to form a unified faceplate having an expanded width to allow for necessary electronics and display size that fits the intended usage. The faceplates can be, for example, connected together using male/female clips  61 ,  62 , as shown, or by using any other connecting mechanism. A cover (not shown) can be used to cover the open ends, such as open end  63 , to hide the unused clips.
