A keypad is not needed because the system is reset by pressing a Test/Silence button built into every detector or sensor. A siren is also eliminated because a sounder in every detector sounds an alarm when any sensor is triggered. This is possible because every detector includes a transceiver that can receive alarm messages from any other detector. AC power wiring is also eliminated because the base station and sensors are battery powered. Only a telephone connection is needed if the system is to be monitored. In apartments or dormitory installations, smoke detectors in one apartment relay alarm messages to the next apartment, and onto the next, and so on, to a centralized base station for the entire facility. The centralized base station can be located in an apartment manager&#39;s office for immediate notification of an alarm, improper smoke detector operation, low or missing battery indications, and dirty smoke detector indications. The two-way wireless alarm system can save many lives in apartments, where smoke detectors batteries are often depleted or removed. 
         [0026]    The related art described above discloses the use of wireless communication devices, and the posting of indicia from a database to a digital display. However, the prior art fails to disclose a combination for replacing the family display normally found on the kitchen refrigerator. The present disclosure distinguishes over the prior art providing heretofore unknown advantages as described in the following summary. 
       BRIEF SUMMARY OF THE INVENTION 
       [0027]    This disclosure teaches certain benefits in construction and use which give rise to the objectives described below. 
         [0028]    It has become commonplace to place photos, business cards, letters, children&#39;s art, and other artifacts on the surfaces of refrigerators where such items are held in place by small magnets. In fact, the kitchen refrigerator has assumed a second role; that of family bulletin board. However, two major problems exist when the refrigerator is used as a magnetic bulletin board. First, items held in place by magnets often are dislodged and fall off the refrigerator&#39;s surface. These items can become damaged or lost. Second, the surface of the average refrigerator is not large enough to hold all of the items that a typical family might want to post there. 
         [0029]    The present invention solves this problem by enabling a very large number of items to be stored and posted on the family refrigerator. This posting function may be enlarged to provide a communications role as well. 
         [0030]    The present invention is a combination apparatus including a food storing and preserving machine, such as a refrigerator, and an electronic information center. An insulated cabinet provides a door enabling access to a refrigerated interior space within the cabinet. The door incorporates an electronic circuit including a computing unit with a digital data processor, data storage module, and a touch-sense display panel. A plurality of LCD panels are each enabled for displaying photos and other indicia composed from indicia data within the data storage module. A data port is configured for receiving information transmitted by wireless means. A software program in conjunction with the computing unit receives information at the data port and stores the information in the data storage module. Operational options may be displayed on the touch-sense display unit for manually directing the computing unit for displaying the indicia on the LCD panels. In an alternate embodiment, the electronic circuit portion of the present invention may be enclosed in a relatively flat case and mounted to an ordinary refrigerator door or side panel. 
         [0031]    A primary objective inherent in the above described apparatus and method of use is to provide advantages not taught by the prior art. 
         [0032]    Another objective is to provide a more convenient and safe manner of using a refrigerator as a family bulletin board. 
         [0033]    A further objective is to provide such an apparatus having a phone capability useable in conjunction with the storage of data such as phone numbers stored in the apparatus. 
         [0034]    A still further objective is to provide such an apparatus that rotates indicia on the family refrigerator automatically or may be used to conduct presentations. 
         [0035]    Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the presently described apparatus and method of its use.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0041]    The following description is provided to enable any person skilled in the art to make and use the presently described invention and sets forth the best modes contemplated by the inventors of carrying out their invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide an overall method and devices for a refrigerator based information system. 
         [0042]    The presently described apparatus may be enabled in two similar embodiments. One, as described below and shown in  FIG. 1 , is a combination apparatus including a food storing and preserving machine, such as a refrigerator, with a built-in electronic information center, the focus of the present invention. The second, is a separate electronic information center identical to the first embodiment except that it is adapted, by magnetic fixtures, or otherwise, to be more or less permanently fastened to an existing but separate refrigerator. In both cases, the critical elements and the manner in which they operate are the same. 
         [0043]    Therefore, now referring to the electronic information center  5 , shown in  FIGS. 1A , and  1 B, several components are operative in achieving the objects described above. The electronic information center  5 , as shown in  FIG. 1 , is encased within a door  7  or other panel of a refrigerator or other like appliance  6 , i.e., a freezer appliance, for instance, or it is encased in its own stand-alone enclosure  5 ′ or enclosures which are adapted to mount, by magnets  5 ″ or similar means to the door  7  or other panel of the appliance  6  as shown in  FIG. 1B . The information center  5  includes a built-in control unit  10  including a digital data processor with operating software program, a data storage module, and a touch-sense screen as a single package. The control unit  10  is mounted so as to be accessible to a person for viewing and selecting choices displayed. It is not meant, herein, to limit the manual control of the present invention to a touch sense panel, as any other well known means for front panel control may be utilized; i.e., buttons, and selection devices such as a computer mouse or roller ball. 
         [0044]    The information center  5  also provides a plurality of local LCD display panels  40  which are each enabled, as will be described, for displaying information stored as data within the data storage module of the control unit  10 , which is also referred to herein as an electronic circuit. The information center  5  also provides various devices for communication between users and the information center  5 , such as a USB port  50  a wireless transceiver  52 , a microphone  54  and speaker  56 . The operating software program is functional for receiving information through the port  50 , transceiver  52  and microphone  54  and storing said information in the data storage module, displaying operational options on the control unit  10 , directing operations of the data processor, and displaying information, such as photographs, on each of the display panels  40 . The operating software may be enabled for responding to spoken requests by a user with artificial language responses through speaker  56 , as are well known in the art so that a “conversation” may be carried on between user and machine as is common with telephone inquires to certain businesses. An example of such a conversation might transpire as follows:
       User: “Wake-up”   Machine: “Can I help you”?   User: “Photos”   Machine: “Thirty-five photos stored in memory”   User: “Scan photo”   Machine: “Ready;” “Scanning,” “Please name new photo”   User: “Picnic on June 7 th ”   Machine: “New photo stored under name picnic on June 7 th ”   User: “Good-bye”   Machine: “Many thanks and good-bye”       
 
       In this sequence the phrases, “wake-up;” “photos;” “scan photo” and “good-bye” are language elements that the system library has been trained to recognize and take action upon, including verbal responses to the user. 
       [0055]    The transceiver  52  is preferably enabled for receiving and sending (transmitting) data by wireless means as for instance by one or more of: IR, WiFi, Bluetooth, RFID and RF transmission technologies or other similar wireless communication methods. 
         [0056]    The information handled by the present invention may be: text, pictures, calendars, graphics, symbols, colors and animation as well as any other type of pictorial material that can be presented on the display panels  40 . Such LCD panels  40  may alternately be plasma panels or CRT devices or other display units of any kind. For instance, digital photographs may be input via the USB port  50 . Photos and other pictorial or textural material may be scanned into a digital form through scanner  70  so as to be stored in the data storage module, and then brought to the display panel  40  for viewing. This simple task takes the place of the mechanical posting of paper-based photographs held on a metal surface such as a refrigerator by magnets, tape or other temporary fasteners. Likewise, a child&#39;s art may be scanned into digital form and displayed on one or more of the display panels. Text messages, famous quotes, poems, and text articles may be displayed in this manner also. The presentation of information may be handled in accordance with Ferragut, et al., U.S. 2003/0014259 which is hereby incorporated herein by reference. Lindler, U.S. Pat. No. 6,535,139 teaches the presentation of information on display screens in a manner used in the present apparatus and therefore is herein incorporated into the present disclosure by reference as well. 
         [0057]    The software program is enabled for adding to, deleting from, shuffling among, and resizing any of the information that is stored within the present invention. The various display panels  40  may be adjusted as to brightness, contrast, color balance, physical orientation and may be enlarged and cropped and even vignetted as desired using well known software routines that are available to the public. All of these capabilities are well known in editing digital graphics. This capability is particularly useful for posting photographs for family and friends to view wherein the photographs may be digitally altered to optimize their appearance. 
         [0058]    Preferably, information in spoken form may be input into the present system using a spoken language recognition software feature, well known in the art, so that information may be adding to, deleting from, shuffling, resized, etc. via voice command. Also, touch-sense selection of options may be used as well or in conjunction with verbal commands. 
         [0059]    Preferably, one display panel  42  is functional as a calendar and, through control unit  10  may be set for day, week, month and year views. This panel  42  can be written on to place notes. 
         [0060]    Through the transceiver  52  the system is able to communicate with hand held devices such as cell phones and PDAs and with remote display screen modules  70 , as shown in  FIG. 3 , which are units that may take the form of a wall hung or surface supported picture, and may be battery operated or use house current for operation. Modules  70  are preferably LCD display panels mounted in picture frames for displaying photos or other materials such as with the display modules  40 . Through the transceiver  52  of the information center  5  the modules  70 , which provide RF receiver and display driver circuitry  72 , display information is able to be sent to the modules  70  for display. 
         [0061]      FIG. 2  is a concept block diagram showing that the present invention represented by “Fridge Panel”  5  is able to communicate using a wireless electronic picture transfer system  5   a , preferably RF based to send information to a host of remote display modules  70  within a certain limited transmission distance such as 400 feet or less. Such a transfer system  5   a  includes control unit  10 , transceiver  52 , receiver and display driver circuitry  72 . This wireless system is preferably in communication with one or more public telephone systems including cell phone systems, as is well known in the art and with the Internet via a wireless connection as is taught by Roh, et al., U.S. 2003/0167785 which is hereby incorporated by reference herein. Curry, et al., U.S. Pat. No. 6,542,497 discloses a wireless gateway system that provides telephone communications and is hereby incorporated herein by reference as one manner of achieving the utility of the present apparatus. Mahoney, U.S. Pat. No. 6,940,951, discloses a speech enabled automatic name dialing system for connection to a telephone system, that includes a user computer with a computer-based address book program for retrieval of name-telephone number data. Mahoney is hereby incorporated herein by reference to enable this aspect of the present invention. 
         [0062]    Preferably, the software in the present invention further comprises a word recognition parser so that scanned business cards, and other text based items, having telephone numbers thereon are able to be recalled by verbal commands and the telephone numbers automatically dialed using the transceiver  52 . To accomplish this, the system includes a phone dialing enablement as part of the software protocol of the system. 
         [0063]    The system is enabled for setting time durations and order sequencing as is well known. Therefore, the transmission and display of graphic or other information may be set to change periodically so that, for instance the local display modules  40  and the remote display modules may change views on a scheduled basis. In this way, the indicia displayed may be programmed to rotate in any selected sequence onto the LCD panels. This may be done to provide a video show to those sitting around the counter in a kitchen, or to provide a refreshing constantly changing review of pictures, art and other items from day to day at any or all of the display devices. The information displayed may be: text, pictures, calendars, graphics, symbols, colors and animation. 
         [0064]    The intent of the present invention is to present pictorial information at a plurality of display screens both local having wired communication links, and remote through wireless transmission, wherein the type of material displayed and the scheduling of such information is programmable at a base station mounted on or in an appliance. Clearly, the appliance may be replaced by any structural surface such as a wall with the present invention built into the wall or hung, or otherwise attached to the wall. 
         [0065]    Clearly, the electronic communication center  5  may be mounted and used as a base unit, and, since it may be attached to a refrigerator or other appliance or a surface of choice, and in a further smaller embodiment, it may be demounted and used as a portable unit movable from room to room to program remote LCD panels by line-of-sight or near line-of-sight communication techniques such as ultrasonic, infra-red, or blue tooth. 
         [0066]    The enablements described in detail above are considered novel over the prior art of record and are considered critical to the operation of at least one aspect of the apparatus and its method of use and to the achievement of the above described objectives. The words used in this specification to describe the instant embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification: structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use must be understood as being generic to all possible meanings supported by the specification and by the word or words describing the element. 
         [0067]    The definitions of the words or drawing elements described herein are meant to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements described and its various embodiments or that a single element may be substituted for two or more elements in a claim. 
         [0068]    Changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalents within the scope intended and its various embodiments. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. This disclosure is thus meant to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted, and also what incorporates the essential ideas. 
         [0069]    The scope of this description is to be interpreted only in conjunction with the appended claims and it is made clear, here, that each named inventor believes that the claimed subject matter is what is intended to be patented.
