- the reduced weight is important when the signage unit 300 is mounted in an overhead location, such as over an employee work area at the point of sale. Also, the reduced weight allows the installer of the signage unit to more easily lift the unit into an overhead position.
- the first mirror 320 is disposed at a non-90° angle relative to the incoming image from the image projection device 305.
- the angle between the image projection device 305 and the first mirror 320 lengthens the optical path in the housing 390.
- the first mirror is in a trapezoidal shape to compensate for the first mirror 320 being disposed at a non-90° angle relative to an incoming image.
- the trapezoidal shape can correspond to the shape of the image incident on the first mirror 320.
- the first mirror 320 is not larger than the size of the incoming image.
- the trapezoidal shape of the first mirror 320 can reduce the size of the mirror and the overall weight of the signage unit 300.
- the image travels the first optical path segment 310 to the first mirror 320, where the image is reflected and directed along a second optical path segment
- the image is transmitted along a third optical path segment 350 to the third mirror 360, where it is reflected and directed along a fourth optical path segment 370 until it encounters the projection screen 380, which contains the image plane of projection lens system 305,
- the projection screen 380 which contains the image plane of projection lens system 305.
- the widest portion of the optical layout of such a system is the image projected on projection screen 380, where the term width refers to the dimension perpendicular to the viewing plane.
- the image on the projection screen 380 is the widest component in the optical layout, other components, in particular mirrors 360, 340, and 320, can be made progressively smaller (in the listed order) without loss of optical function. As a result, the weight of signage unit 300 can be further reduced.
- the smaller size of the first mirror 320 allows the housing 390 to be made narrower at the rear side 321 of the housing 390 than at the front side 323 of the housing 390. This feature can allow signage unit 300 to better fit into corner locations, a useful feature in retail environments where customer viewable surface area can be of high value.
- Mrrors 320, 340, and 360 can be of any suitably reflective material, such as a thin metallic layer coated on a suitable substrate.
- one particularly suitable type of mirror includes a metal frame over which is stretched a metallized or otherwise reflective polymeric film.
- Mirrors of this type are disclosed in U.S. Patents 5,247,395 and 5,841,595, herein incorporated by reference, and are commercially available from Hudson Photographic Industries, Inc., of Irvington, New York.
- Other mirrors can be used in polymeric interference mirrors.
- Such mirrors include, for example, multilayer reflective mirrors such as those described include, for example, U.S. Patents Nos. 5,448,404, 5,699,188, and 5,825,542 and PCT Patent
- FIG. 10 is a schematic cross-section of one example of a suitable lightweight mirror.
- the mirror includes a reflective film 341 stretched over a lightweight frame 342.
- the reflective film 341 includes a layer of thin plastic film 343, a reflective material layer 344, and a protective coating 345.
- the reflective material layer 344 includes a first surface 346 and a second surface 347 with the thin layer of plastic 343 bonded to the first surface 346.
- the protective coating 345 is applied to the second surface
- the lightweight frame 342 includes a support surface with an adhesive 348 disposed on the support surface.
- the reflective film 341 is adhered to the support surface of the lightweight frame 342.
- the lightweight frame 342 includes a frame support 349 filled with a lightweight material 351.
- the frame support 349 can be aluminum or other lightweight metal or plastic material, and the lightweight material 351 is a polymeric foam.
- any lightweight metal or material can be used to construct the lightweight frame.
- the mirrors 320, 340, and 360 are substantially flat.
- Other embodiments can include mirrors having an amount of curvature.
- Such curvature can, for example, be spherical, so as to incorporate optical power into the optical system, thereby altering the size of the projected image or altering the location of the image plane.
- cylindrical curvature can be incorporated into one or more of the mirrors so as to alter the aspect ratio of the projected image for the purpose of accommodating a screen having a particular aspect ratio.
- the data provided to imager 304 can be altered to compensate for distortion effects, thereby providing a final image having correct proportions.
- the signage unit 300 includes a mirror adjustment mechanism (not shown).
- the adjustment mechanism has an adjustment control, which extends partially beyond an exterior surface of the housing 390.
- the mirror adjustment mechanism permits the adjustment of the position of at least one of the mirrors used for directing the image.
- the mirror adjustment mechanism can adjust a mirror laterally in one or more directions or rotate the mirror the housing 390.

- the signage unit 300 includes multiple mirror adjustment mechanisms that correspond to the each of the mirrors disposed in the housing
- the mirror can be adjusted manually from within the housing.
- the length of the optical path from the image projection device 705 is the sum of the lengths of image paths 730, 750, and 770 . This may be less than the path length found in the three-mirror embodiment, and can result in the image distance of the projection lens system being shorter.
- the two-mirror system has the advantage of reduced reflection losses and reduced signage unit weight.
- a light redirecting element 782 for example, a Fresnel lens, can be useful.
- Figure 8 shows another embodiment of a signage unit 800 employing only one mirror 860.
- the image distance of the projection lens system of the image projection system 805 may still be shorter, since the optical path is now only the sum of the lengths of path segments 810 and 870. If the housing can be made larger, optical path segments 810 and 870 can be made longer.
- a light redirecting element 882 for example, a Fresnel lens, can be useful.
- FIG. 9 another embodiment of a signage unit 900 is portrayed where no mirrors are used.
- This configuration can be suitable for some installations where a long space, which is relatively low in height, is available for mounting the signage unit 900.
- a light redirecting element 982 for example, a Fresnel lens, can be provided.
- an air flow system 394 controls the intake of air into the internal volume 384 of the housing 390 to filter the air entering the internal volume 384 of the housing 390, cool the internal volume 384 of the housing 390 and image projection device 305, pressurize the internal volume 384 of the housing 390, or a combination of these functions.
- Air intake is controlled to exclude the large amount of air borne particulates generated in, for example, the restaurant environment from the interior volume 384 of the housing 390. If air intake is not controlled, particulates, such as dust and grease, can enter the internal volume 384 of the housing 390. Air borne particulates within the internal volume 384 of the housing 390 can deposit on components, such as the mirrors or the image projection device. Deposits on the components within the interior can lead to reduced quality of the image(s) projected on the projection screen 380 or to damage to the components.

- the air flow system 394 provides cooling of the image projection device 305 and the internal volume 384 of the housing 390.
- the air flow system 394 includes filter 392, inlet port 393, and an exit port 397 defined by the housing 390. Warmed air can pass out of the internal volume 384 of the housing 390 through the exit port to cool the image projection device
- the exit port 397 provides a suitable level of flow resistance, so as to maintain a positive pressure within the internal volume 384 of the housing 390, while still allowing air to exit the housing 390.
- the air flow system 394 includes an air valve 398 disposed over the exit port 397 to prevent backflow of air and influx of contaminants into the internal volume 384 of the housing 390.
- the air valve 398 can be controlled, for example, by the pressure difference between the internal volume 384 of the housing 390 and the ambient pressure outside the housing.
- a wall defines a first region and a second region within the housing 390.
- the wall is transparent.
- the image projection device 305 is disposed within the first region of the housing and the mirror system 302 is disposed within the second region of the housing 390.
- the wall can provide a partition (optionally, airtight) to isolate non-cooled, contamination-sensitive optical components from those components that require cooling.
- the air flow system 394 is configured and arranged to provide a positive pressure within the first region of the housing 390, to cool the image projection device 305 and the first region, and to filter air.
- more than one air flow system 394 can be provided for the internal volume 384 of the housing 390.

- turnbuckles or other length adjustment devices can be interposed in the cable to provide adjustment of the cable lengths and hence adjustment of the height and orientation of signage unit 300.
- Other mounting devices include, but are not limited to, brackets bolted or otherwise fastened to signage unit 300 and to overhead structures.
- Projection Screen It is well known that the appearance of food, especially its color, is important in its customer appeal. It is therefore useful, in the graphic presentation of food items, to present images which are appealing and realistic portrayals of those foods.
- the term "realistic" will mean that the graphic portrayals presented by signage unit 10 will evoke in the viewer a sensation of the probable taste of the food being portrayed, and that when the food item is eaten, the viewer will feel that the graphic portrayal is in some way consistent with the actual taste. It is also useful if the effects of ambient light on the graphic portrayals presented by signage unit 10 are reduced.
- the signage unit 300 includes a projection screen 380 that is a rear projection screen of a type which is especially suitable for portraying graphic images of foods, in that it suppresses ambient light effects while allowing high image contrast and intense colors. It does this by providing arrays of focusing elements 410 surrounded by light absorbing material 420, as shown in Figure 4.
- Other projection screens can also be used.
- the projection screen 380 includes an array of light focusing beads 410 and a transparent support 430.
- the transparent support 430 includes a transparent support surface 432.
- the array of light focusing beads is disposed on the transparent support surface 432.
- the light focusing beads 410 are transparent, however, any light focusing material can be used.
- Figure 4 shows, an individual light focusing bead 412 focusing projected light rays 401 and 403 from an image projection device.
- the light focusing bead 412 focuses light rays 401 and 403 to a small area coincident with a bead area 425, which allows the rays to emerge as rays 405 and 406.
- Each light focusing bead in the array of light focusing beads 410 focuses light rays incident to that individual bead.
- the projection screen 380 includes a light absorbing layer 420 disposed on the transparent support surface 432.
- the array of light focusing beads 410 and the light absorbing layer 420 create a layer 415 which allows image rays 401 and 403 to pass through the light focusing beads 410 at the bead area 425.
- Much of the ambient light 411 is absorbed by the light absorbing layer 420, while a remaining portion enters the bead area 425 where it is diverted in various directions and absorbed by, for example, the internal walls of the housing of the signage unit.
- rear projection screen images can further be enhanced by interposing a diffusing layer 550 between a transparent substrate 530 and a layer 515 containing light focusing beads 510 and a light absorbing material 520.
- Suitable rear projection screens are disclosed, for example, in published PCT Patent Application WO 98/45753, incorporated herein by reference.
- the light focusing in the rear projection screen can be performed by an array of cylindrical or spherical lenses, which can be produced, for example, by microreplication methods known in the art.
- projection screen 380 can further incorporate a suitably oriented light polarizing function, which can, for example, reduce the deleterious effects of ambient lighting.
- multiple signage units 602, 604, 606, and 608 are shown in an array. Any number of signage units can be used for the array.
- each signage unit has a housing.
- the multiple signage units 602, 604, 606, and 608 are placed in a single housing 610. If all of the displays are placed in a single housing 610, a single rear projection screen can optionally be used for all of the displays.
- the multiple displays can include pictorial representations of food items and written words.
- Figure 6 shows individual displays for different food items.
- a single display is created from integrating individual information displays or from a single image projection device.
- the array of signage units display, for example, menu items, prices, specials, moving displays, sequential displays, child or adult oriented information, commercials, inventory information, or customer order information.
