Description: MULTΓMODE APPARATUS WITH COMMUNICATION AND CONTROL FEATURES TECHNICAL FIELD OF THE INVENTION In one aspect the present invention relates to novel apparatus having the capability of communicating with household (and/or other) appliances. In other aspects, the present invention relates to an apparatus as characterized in the preceding paragraph which: can communicate with appliances via existing electrical wiring; can process and display messages originated by an appliance and forward those messages to a designated cellular phone. can process and display messages transmitted to the apparatus from a cellular phone. In yet another respect the present invention relates to novel integrated units for apparatus as characterized above which have multiple modes of operation, at least: (1) a TV mode in which the unit has the capabilities of a television set, and (2) an APPLIANCE mode in which a user can send commands by way of the integrated unit to an appliance served by the integrated unit, using an input device such as a cellular phone, a keyboard, or a remote control. The integrated unit is also designed to receive and display messages transmitted to the unit from a cellular phone. BACKGROUND OF THE INVENTION Heretofore invented have been certain new and novel appliances with multiple, user-selectable operating modes. These appliances are capable of carrying out different ones of multiple functions. A function is called up by choosing the appropriate, user-selectable mode. Examples of the operating modes which different ones of the subject appliances have and the function of the appliance in each of these modes appear below. Copending application No. 09/116,785 discloses, in detail, systems with integrated units of the character just described which have an APPLIANCE mode of operation. In that mode, the systems disclosed in the '785 application have the ability to make information on the status of an appliance available: (a) on a display screen of the unit, and (b) to a repair or service facility at a site removed from the loci of the appliance and the integrated unit. The systems disclosed in the '785 application also have the capability of controlling the operation of appliances in addition to the just-described appliance monitoring and reporting features. They also have the capability of supervising more than one appliance, and a wide variety of appliances can be monitored. These include, without limitation: electric stoves and ovens, refrigerators, freezers, window and central air conditioning systems, central heating systems, room heaters, and central vacuuming systems. SUMMARY OF THE INVENTION The apparatus of the present invention is akin to that disclosed in the '785 application in that it has appliance monitoring, controlling, and reporting functions. The systems disclosed herein, however, have integrated units with a GSM or comparable device which enables the integrated unit to call a specified cellular phone and report the existence of an appliance-related problem to the person answering the phone. Conversely, a person using the designated cellular phone can call the integrated unit and leave a message on a display screen component of that unit. Another novel feature of the apparatus disclosed herein is that a message identifying an appliance-related problem can be placed on a screen of the display unit irrespective of the mode in which the system is operating, preferably in a manner which is unobtrusive and does not more than minimally distract the system user (and/or other person(s)) from the activity such as watching TV in which he is engaging. Yet another advantage of apparatus as described herein is that icons representing the different appliances supervised by the integrated unit of the apparatus automatically appear when the APPLIANCE mode of operation is selected. Selecting an icon brings up a screen displaying the status of the associated appliance and, optionally, one or more icons which can be employed to control the operation of the appliance. Still another novel feature of the systems disclosed herein is the use of network interface boards (NIBs) in the integrated units of the apparatus and the inclusion of a complementary NIB in each associated appliance. The NIBs embed messages in network communications protocols, and strip the protocols to retrieve the messages. This schemata allows in place electrical wiring to be used to transmit messages between the integrated unit of the apparatus and the associated appliances. The objects, advantages, and features of the present invention will be apparent to the reader from the foregoing and the appended claims and as the ensuing detailed description and discussion of the invention proceeds in conjunction with the accompanying drawing.

DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawing, FIG. 1 depicts a complement 20 of household appliances and a MIE appliance 22 embodying the principles of the present invention. The MID appliance has an integrated unit (or module) 24; a remote control 26; and, optionally, a keyboard 28. The integrated unit 24 of the system 22 communicates with the representative, illustrated appliances in complement 20 - oven 30, refrigerator/freezer 32, dishwasher 34, and washer/dryer 36 - via installed electrical wiring 38 and the power cords (or local electrical wiring) 40-46 of the appliances. The integrated unit 24 is also designed to communicate with a specified cellular phone 48. Exemplary MIE 22 has the following modes of operation: TELEVISION CD INTERNET SECURITY/MONITOR APPLIANCE How MIE appliance 22 functions in each of the first four modes is described above in that section of the specification entitled SUMMARY OF THE INVENTION. Operation of the appliance in the APPLIANCE mode is discussed below. It is not necessary that MIE appliance 22 have all five of the operating modes identified above. One or more of these modes may be omitted or a mode may be disenabled, typically with a provision for mode activation as described in copending application No. 09/478922 filed 6 January 2000. Referring now to FIGS. 1 and 2, the integrated unit 24 of system 22 includes: a display unit 52 with a flat screen 54. The display unit 52 is mounted to the integrated unit by a universal coupling 56 which allows the display unit screen to be rotated and tilted to face a viewer and to be folded up against the bottom 58 of integrated unit cabinet 59 when MIE appliance 22 is not in use. The details of the universal coupling are not part of the present invention and will accordingly not be described herein. The universal coupling is, however, disclosed in detail in copending application No. 09/516,427 filed 1 March, 2000, to which the reader may refer, if desired. Messages warning of existing or potential problems are displayed on the screen 54 of display unit 52. If the message is not acted upon in a specified period of time, integrated unit 24 forwards the warning message to cellular phone 48. Commands and data can be inputted to module 24 by onboard controls 60 or with the remote control 26 or optional keyboard 28. Remote control 26 and keyboard 28 will be referred to hereinafter only to the extent that they are relevant to an understanding of the present invention. Details of these devices can be found in U.S. Patent No. 5,724,102 and in copending application No. 09/466,103 filed 12 December 1999. Audio speakers 62 and 64 are attached to opposite ends of integrated unit 24. This eliminates speaker wires and otherwise facilitates the installation of MIE appliance 22 and enhances the appearance of the installation. The integrated unit 24 of system 22 with speakers 62 and 64 is designed to be mounted in an overhead cabinet system 66; it is more specifically designed to be mounted beneath two adjacent center cabinets 68 and 70. Those cabinets are located between outer overhead cabinets 72 and 74 of greater depth. Cabinets of the character illustrated in FIG. 2 are often supplied in conventional widths and heights. The module 24 of MIE appliance 22 is preferably designed and dimensioned for compatibility with such cabinets of standard dimensions. The two shorter or shallower cabinets 68 and 70 between longer cabinets 72 and 74 define a downwardly opening, horizontally extending recess 76. The assembly 78 of integrated unit 24 and audio speakers 62 and 64 is dimensioned to fit into recess 76 with: (a) the ends 80 and 82 of assembly 78 abutting outer cabinets 72 and 74, and the upper wall 84 of the assembly flush with the bottoms 86 and 88 of the two outermost cabinets. Details of the arrangement for mounting integrated unit assembly 78 to cabinets 68 and 70 appear in the copending '427 application and will not be unnecessarily repeated here. Referring now primarily to FIG. 2, the illustrated module 24 also has a player 94 for a conventional or interactive, laser readable disk 96. This player is optional; it can be provided or omitted, depending upon the market for which the system is intended. Commands for operating the TV and disk player and for selecting the mode of operation of MIE appliance 22 can be inputted by the above-mentioned remote control 26 or keyboard 28 or by the FIG. 2 onboard pushbutton controls 60. One representative onboard control is identified in FIG. 4A by reference character 98. The operating components of integrated unit 24, together with certain ancillary devices which may be activated in different operating modes of MIE appliance 22, are depicted schematically in FIGS. 4A, 4B, and 4C. The integrated unit operating components include a mode selection register 100 and a video/audio switch 102, both activated when a particular one of the appliance 22 operating modes is selected. The video/audio switch channels the input available in the selected operating mode to the screen 54 of display unit 52 and to audio speakers 62 and 64. As a single example, when the TELEVISION mode is selected, a connection to a source for a television signal such as an antenna, a cable, and/or a VCR is made through switch 102. External components controlled by the integrated unit 24 of MIE appliance 22, in this case in a SECURITY mode of operation, are incorporated in an entryway module identified by reference character 104 in FIG. 4A. These components include a microphone 106, an entryway speaker 108, and an electrically operated door latch 110. Optionally located at the same entryway (not shown) as module 104 is a camera 112 which is designed to display an image of a person at the entryway on display unit screen 54. Camera 112 can otherwise be used to monitor an alternate location such as a baby's bedroom. The operation of an entryway security system of the character just described is disclosed in detail in copending application No. 09/116,825 filed 16 July 1998, to which the reader may refer if desired. Other major operating components of integrated unit 24, primarily located on secondary board 114 or controller board 116, are listed below along with the function of each component. Also located on or operatively associated with secondary board 114 are the following additional components: It was suggested above that appliance module 24 can transmit and receive data via a telephone line as well as by cellular phone linkups. The telephone line is shown in FIG. 4A and identified by reference character 140. As shown in FIG. 4A, module 24 also has a USB port 142 as well as links (or connections) 144, 146, and 148 for transmitting appropriately formatted data to a printer and to video and audio devices— viz., display unit screen 54 and speaker units 62 and 64. The module 24 of MIE appliance 22 preferably also has an Ethernet port 150. This: (1) allows MIE appliance 22 to be networked to compatible devices, and (2) allows appliance 22 to be connected to the Internet via a DSL or other broad bandwidth link. TELEVISION, CD (if present), APPLIANCE, SECURITY / MONITOR, and INTERNET modes of operation of MIE appliance 22 may be selected by the user of that appliance with push button mode controls 152, 154, 156, 158, and 160 of remote control 26 (see FIG. 3) or with corresponding pushbuttons of keyboard 28, or with corresponding ones of the onboard controls 60. Referring now to FIG. 4C, the electronic video/audio switch 102 of module 24 is illustrated as a mechanical switch in the interest of clarity. This switch has five positions labeled 1-5. The pressing of one of the five mode buttons 152 - 160 causes the corresponding number— shown in the following table— to be placed in mode selection register 100. Video switch 102 is thereupon set to the number in selection register 100, causing MIE appliance 22 to operate in the selected mode. Additional details of the operating components of MIE appliances of the same general character as appliance 22 are to be found in the following U.S. patent and copending applications hereby incorporated by reference herein. UNITED STATES PATENT COPENDING U.S. APPLICATIONS The functions of the other buttons on remote control 26 and the keys on keyboard 28 are described in the '102 patent and in the copending '103 application and accordingly have been omitted in this specification as they are not germane to an understanding of the present invention. Referring still to the drawings, FIG. 8 shows a display 162 that appears on screen 54 when a user of MIE appliance 22 selects the APPLIANCE mode of operation by pressing remote control mode button 160. This display includes a banner 164 with the current date and time and icons 166, 168, 170, and 172 respectively representing oven 30, refrigerator/freezer 32, dishwasher 34, and washer/dryer 36 of FIG. 1. Also, the display may include a warning such as the one identified by reference character 174. This aspect of invention is discussed in detail below. In the typical, FIG. 5 scenario, to which the ensuing disclosure is for the most part directed in the interest of clarity and brevity, the MIE appliance user employs remote control 26 or keyboard 28 to select oven icon 166. This brings up on screen 54 of display unit 52 the display shown in FIG. 9 and identified by reference character 176. This display includes date and time banner 164 and a block 178 in which the status of oven 30, represented by oven icon 166, is displayed. In the typical scenario under discussion, the user of MIE appliance 22 wishes to turn oven 30 off and accordingly selects OFF button 180 in display block 178 with remote control 26 or keyboard 28. Thereupon, a "oven off command is- transmitted from controller board 116 (see FIGS. 1 and 4A) to appliance network interface board (NIB) 128. NIB 128 embeds this command in an appropriate network protocol and sends the message over electrical wiring 38 and local power cord 40 to oven 30. An oven NIB 182 (see FIG. 1) detects the message, strips off the network communications protocol, and sends the "oven off command to the oven controller 183 of oven 30 which, upon receipt of the command, turns oven 30 off. Oven NIB 182 detects a signal from the oven controller 183 confirming that the oven has been turned off, embeds this confirming message in the network communications protocol, and sends the message to NIB 128 of the MIE appliance integrated unit 24. NIB 128 strips the network communications protocol from the confirming message and transmits the latter to controller board 116. This results in a confirmation that the oven has been turned off being displayed to the MIE appliance user. In the embodiment of the invention under discussion, the OFF label of icon 180 (see FIG. 9) changes to START, and the color of the oven icon 166 changes from yellow to green. In the event that an appliance becomes disconnected from the existing electrical wiring over which the MIE appliance communicates with said appliance, the respective appliance icon on the MIE's display screen will be greyed out and will become inaccessible to the user. Commands are selected by using LEFT, RIGHT, UP, and DOWN buttons 200, 202, 204, and 206 of remote control 26 (see FIG. 3) or the corresponding buttons of keyboard 28 — if present — to move the cursor arrow (see FIGS. 8 and 9) icon 190 representing the desired action. GO button 192 (see FIG. 3) is pressed to execute the command. Turning now to FIG. 6, the user of MIE appliance 22 may also use cellular phone 48 to transmit the "oven off command to oven 30. To do this, (see FIG. 6), the user calls the GSM module 132 of MIE appliance integrated unit 24. Once the connection is made, the user enters by way of the cellular phone keyboard a numerical code corresponding to the "oven off command. This command is received by GSM module 132 and transmitted to controller board 116. Controller board 116 then sends the "oven off command to appliance NIB 128, wherein the command is embedded in the network protocol, and transmitted to the NIB 182 of oven 30, in the same fashion as if the "oven off command were originated by remote control 26 or keyboard 28. The confirming message is in this case displayed on screen 54 and also relayed via GSM module 132 of the integrated unit 24 to cellular phone 48. Turning next to FIGS. 7 and 10, it was pointed out above that, if a problem with a household appliance supervised and controlled by MIE appliance 22 occurs, a warning message will be displayed on the screen 54 of display unit 52 irrespective of the mode in which the MIE appliance is operating. In the representative example to which FIGS. 7 and 10 are directed, the user of MIE appliance 22 (or another person) has selected the TV mode of operation by pressing push button 156 on remote control 26 or, alternatively, if a keyboard is present, by pressing the corresponding mode selection button on the keyboard. It is further assumed in this scenario that, while TV is being watched, the door of refrigerator/freezer 32 is left ajar. This condition is detected by the refrigerator controller 185 which sends a "door ajar" alarm to the NIB 184 of the refrigerator. The refrigerator NIB 184 embeds the "door ajar" alarm in the selected network communication protocol and sends the alarm over power cord 42 and installed electrical wiring 38 to the appliance NIB 128 of the supervising MIE appliance 22 (see FIG. 4B). Here, the network protocol is stripped away and the alarm message transmitted to the MIE controller board 116, which sends the message to the screen 54 of MIE display unit 52. To minimize interference with the viewer's activities, the warning message is preferably displayed toward the bottom of screen 54 in a window as identified by reference character 174 in FIG. 10. At the same time, and as shown in FIG. 7, a countdown timer 173 (see FIG. 4a) is started. At the end of the timing period, controller board 116 determines whether the problem has been remedied; i.e., whether the refrigerator door has been closed. If it has, the warning message display 174 is removed from screen 54, and the program ends. If the refrigerator door has not been closed before the time lapses, controller board 1 16 sends the "door ajar" message to GSM module 132 which calls cellular phone 48 and displays the alarm message on the cellular phone screen (not shown) to the person answering the phone. Where the fault which initiated the warning message is not remedied, the message display window 174 remains on the screen for a preset length of time and is then removed. How messages received from the appliances supervised by MIE appliance 22 and messages received from cellular phone 48 are displayed is shown in more detail in FIG. 11. These messages appear on screen 54 in window 194 irrespective of their origin. Scroll UP and scroll DOWN buttons 196 and 198 allow a user to bring up in window 194 messages which are hidden if window 194 is filled and there are additional messages. The cellular phone icon 208 is displayed (see FIG. 8) to alert the MIE appliance user that one or more messages have been received from cellular phone 48. A scroll button is selected with LEFT, RIGHT, UP, and DOWN buttons 200, 202, 204, and 206 and activated with GO button 192. Integrated unit 24 can also be used for purposes not discussed above, for example, energy management. As an example, many utilities charge a premium for electricity used at a rate above a floor level, especially during peak hours. It may happen that oven 30 is turned on while dishwasher 34 is running. If it does, integrated unit 24 can put the dishwasher into a pause mode in which it does not consume electricity so that the floor level is not exceeded and the premium avoided. The invention may be embodied in many forms without departing from the spirit or essential characteristics of the invention. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive. The scope of the invention is indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
