A type of display board is currently available for providing an interchangeable background, covered by a transparent acrylic sheet. In one style of this type of board, the acrylic sheet is mounted to a hinge at its top and retained by magnets at its bottom. The magnets are attracted to a steel sheet that is about 0.32 mm thick, to which the acrylic sheet hinge is also mounted. To provide or change the semi-permanent display, the cover is opened and printed media, in the form of printed coated paper or polymeric material is placed over the steel sheet, and the Plexiglass cover is closed. This provides the user with a board having a printed background, but that he can write on with a marker, and later erase. As an example, a basketball coach may want a board having a basketball court scheme as a background, upon which he can draw basketball plays. Using the board described above he could order a basketball court scheme on cardboard or polymeric media and place it between the metal backing and the acrylic sheet cover, close the cover, and then mark the plays on the acrylic sheet. During football season the board could be provided with a football scheme background and provided to the football coach, who could draw football plays on it. In a medical environment, a board assembly in an ear, nose and throat specialist's office could be used to show a background media of the human throat, permitting the physician to mark on the clear plastic over this media, to illustrate a throat procedure. The same style of board could be used in a cardiologist's office with media showing the interior of the human heart, to permit the cardiologist to explain a cardiac procedure to a patient.
Unfortunately, many of the available boards of this nature are problematic. First, many include a wood backing to the steel sheet, thereby making the board quite heavy. Moreover, wood forming a portion of the board causes the board's use to be prohibited in many portions of a hospital, including patient rooms. Any porous material, such as wood, provides places for microbes to dwell, where it is difficult for sanitizing agents to reach. Also, as the principal structure of the board is wood, the steel sheet tends to be quite thin, on the order of a third of a millimeter. Also, a frame is generally used to hide the layered construction from users, and to forestall potential delamination. This adds to the weight of the board and provides additional covered areas for harmful microbes to live.
Further, in some hospital rooms a “terminal cleaning” is performed when a patient with a highly infectious condition is discharged. In this procedure, everything in the room is hosed down with bleach. Boards that include wood or a laminated panel as part of their construction tend to be damaged by being exposed to large amounts of bleach water. In like manner, boards containing wood may also be more vulnerable to becoming warped if left outside in the rain, as an advertising sandwich board might be left.
Finally, the differing coefficient of thermal expansion of the wood versus the steel sheet tends to cause warping in the steel sheet. It appears that this has necessitated the use of a thicker acrylic sheet than would otherwise be necessary, so that the weight of the acrylic sheet can hold the media in place, even against an uneven backing surface.
The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope. In various embodiments, one or more of the above-described problems have been reduced or eliminated, while other embodiments are directed to other improvements.
In a first separate aspect, the present invention may take the form of a display assembly, having a base comprised of polymeric material, and having a front wall of at least one hundred square centimeters in area, and a rearward-extending base peripheral wall of at least 0.5 cm height. The front wall has raised regions and recessed regions that extend at least as far back as the peripheral wall at its furthest rearmost extent, so that when the base is placed against a flat surface the back of the recessed regions touches the flat surface. A polymeric cover is adapted to tension fit to the base, the polymeric cover including a generally transparent front wall. Translucent display media interposed between the base and the cover and a set of energy efficient lighting devices disposed in the recessed regions.
In a second separate aspect, the present invention may take the form of a display assembly, having a base comprised of polymeric material, having a front wall of at least one hundred square centimeters in area, and a rearward-extending base peripheral wall of at least 0.5 cm height. The front wall has raised regions and recessed regions, and the recessed regions are recessed such that their backs extend at least as far back as the peripheral wall at its furthest rearmost extent, so that when the base is placed against a flat surface the back of the recessed regions touch the flat surface. Also, a polymeric cover is adapted to fit over the base, the polymeric cover including a generally transparent front wall, and a rearward extending cover peripheral wall, sized to fit about the base peripheral wall, so that when the cover is placed over the base there is a slight tension between the cover peripheral wall and the base peripheral wall. Finally, display media is interposed between the base and the cover.
In a third separate aspect, the present invention may take the form of a method of updating an electrophoretic display, that utilizes an electrophoretic display capable of receiving and displaying a transmitted digital photograph, a marker and a digital camera capable of transmitting digital images to a destination, the display including a transparent cover that can be marked on by the marker. An image is displayed on the electrophoretic display, and markings are made on the cover with the marker. A digital photograph is of the display with the digital camera and marked cover. The photograph is sent to the electrophoretic display, which displays the photograph on the electrophoretic display, thereby displaying both the image and the markings.
In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the drawings and by study of the following detailed descriptions.
Exemplary embodiments are illustrated in referenced drawings. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.
In the context of this application an energy efficient lighting device must produce at least 50 lumens per watt. A light emitting diode (LED) is one example of an energy efficient lighting device.
The assembly 10 and system described above have many advantages. Using the steel plate 13 as the structural support as well as the magnetic backing permits the creation of a lighter board, relative to currently available boards, of roughly one pound per square foot of board, versus about two pounds per square foot of board for currently existing boards. Further, because a thicker steel plate is used, more magnetic attraction is formed with the same power magnet. As a result, media may be magnetically retained on the exterior of the polymeric cover 12. This permits a system including magnetic media 23, designed to be stuck to the outside of the cover 12. For example, in a hospital setting, an assembly 10 can be provided on the door of each patient room, and magnetic media advisories can be attached as desired. For example, magnetic media 23 advisories for MRSA, could be kept on hand and deployed on assemblies 10 as required, to affect a warning to health care workers. Such magnetic media could be fashioned to be very prominent and to catch the attention of medical workers, more so than a simple message written using a marker. A magnetic media background 24 can be deployed directly on plate 13, to provide a semi-permanent background. For example, in the example given above, this could be provided for each room board 10, and changed seasonally to reflect different hospital initiatives.
In one embodiment plate 13 may be “dimpled”—that is, looking at plate 13 from the front a number of indents would be visible, and viewing from the rear, corresponding protrusions. These dimples both create some depth for plate 13 and provide a number of places where a drill can be used to broach plate 13, to permit the introduction of a fastener such as a wood screw, which may then by screwed into a wall (not shown) to support assembly 10. Also, a tray on the bottom of assembly 10 may be provided to hold markers and an eraser. In a preferred embodiment, this tray is attached lightly, so that it can easily snap off, and is made with edges that have all been blunted, as the steel trays currently in use have proven to be a hazard to those working with these boards, as some have been cut by the steel trays.

The many advantages of assembly 210 may now be considered. The entire assembly can be quite light, as base 212, printed media 230 and cover 240 can be made of lightweight polymeric material and steel plate 222 can be as little as 0.1 mm thick, as in the embodiment of assembly 210 plate 222 is not used for structural support. If it is to be used in a hospital room, assembly printed media can indicate where information can be written on cover 240 with a marker provided for this purpose. If a patient is allergic to a medicine or a food, a magnetic element 250 bearing this information in a bright and bold manner may be placed on cover 240 and retained by magnetic force to plate 222, thereby providing a very clear warning, that may be very difficult to fail to notice. In this manner, a hospital can facilitate the task of the medical staff in ensuring that health care workers are clearly notified of the many important factors that must be taken into account in providing patient care. This is always a huge challenge in a busy hospital that must provide appropriate service to a broad array of patients having many idiosyncrasies in their conditions. Also, because no wood or laminated materials are used in assembly 210 it can be exposed to water, for example during a terminal clean, or as an outside display periodically exposed to rain or cleaning fluids, without fear of damage being incurred.
Because it is releasably retained by magnets 218, steel plate 222 does not obstruct installation of base 212, and further permits easy removal in the event that assembly 210 and the set of screws must be accessed for removal. Also, assembly 210, could be prepared with a graphic representing an organ or the human body as whole on printed media 230, thereby serving as an educational material that directly benefits patients. Such an assembly 210 would permit a physician to mark on the cover 240, for example to help explain a procedure to a patient, thereby greatly facilitating physician patient communications. Further, such an assembly could display the name of a pharmaceutical company or a pharmaceutical and could be distributed as a service to hospitals by a pharmaceutical company, without violating current law.
Further, using a set of assemblies 210, it would be possible to implement a system and method in a hospital for increasing staff awareness of patient conditions requiring special measures. Each of a set of patient rooms is equipped with an assembly 210 for each bed in the room. When a new patient is admitted to the room, patient identifying information is written on the cover 240 with markers that are also provided. Then, if the patient has a condition requiring special treatment, such as MRSA, a magnetic element 250, taken from a set of magnetic elements 250 provided, which collectively can provide warning for any one of a number of different conditions requiring special treatment is stuck on the cover 240 and retained magnetically by magnetic attraction to steel plate 222. Elements 250 may be color-coded by condition type and each may bear a distinctive design, so that a medical staff member is quickly made aware of the patient condition or conditions requiring special handling.
In a further detail, a pair of raised areas 260 in a transverse one of channels 214 facilitates attachment of a tray for markers. Such a tray is made of polymeric materials and is wedged into channel 214 and held in place by the channel walls and by raised areas 260. In like manner, a pair of raised areas 270 in a longitudinal channel facilitate the attachment of a marker tray if the board is oriented so that it extends horizontally more than vertically. The advantage of a marker tray made of a polymer and held in a channel by raised areas 260 or 270 is that if a person accidentally walks into such a tray it is easily dislodged. Accordingly, it is far less likely, both because of the softer polymeric material used and because it is more easily dislodged to injure a person who encounters it.

In a further aspect, the may be present in any of the embodiments 10, 210, 210′, 211 or 210″, a “keying” scheme may be used to restrict that use of the assembly to display materials from a single source. For example, an element of a particular shape may extend out of margin 216′, so that only display material having a matching shape will fit into the available area. The affordable care act greatly restricts the goods that pharmaceutical companies can provide for free to doctors to those goods that may be directly used to help patients. If the use of the display assembly 10, 210, 210′, 211 or 210″ is restricted to printed material that is provided directly by a pharmaceutical company and that aids the doctor in explaining a health condition, then this type of gift may be allowed. It is a particular advantage that the doctor can write on transparent cover 240 (or 240′) to help explain a medical condition or treatment.
