The foregoing Summary, as well as the following detailed description of preferred embodiments of the present invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there is shown in the drawings an embodiment which is presently preferred. It is understood, however, that the invention is not limited to the precise arrangement and instrumentality shown. In the drawings:
FIG. 1 is a schematic diagram of a system according to a preferred embodiment of the present invention.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
The words “a” and “one” are defined to include one or more of the referenced item unless specifically stated otherwise. The term “data entry device” as used in the claims and in the corresponding portions of the specification, means “any one of a keyboard, a numeric pad, a separate computer or processor, a bar code reader, a touch pad, a touch sensitive screen, a voice recognition system, or any other known method of entering data into a processible format, such as that used by computer processors and personal computers”. While many embodiments of the present invention will be described below, those of ordinary skill in the art will appreciate from this disclosure that any of the steps or system components described in one embodiment can be combined with any of the other described embodiments.
Referring to FIG. 1, wherein like numerals indicate like elements throughout, the system 10 of the present invention preferably provides a “smart” refrigerator 12 that facilitates the monitoring of the freshness of foods and/or drinks contained therein. The refrigerator 12 preferably includes onboard circuitry 14, such as a PC processor, and/or is in communication, via a wireless connection or a hard wired connection, to a separate computer 16. Alternatively, the computer 16 can be located next to the refrigerator 12 to monitor food and/or drink while not being actually connected or in communication with the refrigerator 12. One method and apparatus for partially connecting and/or integrating a computer or processor with a refrigerator for specific functions is shown in U.S. patent application Ser. No. 10/344,937 which is hereby incorporated by reference herein as if fully set forth in its entirety.
In one preferred embodiment, at least one of the interior portions of the refrigerator, such as a crisper or other interior surface, includes a small data entry device 18. When food and/or drink is placed in the refrigerator, the data entry device 18 is used to enter the type of food and/or drink that is being positioned in the refrigerator 12 as well as some date data that will allow the relative freshness of the food and/or drink to be estimated by the processor 14 or the computer 16. For example, a user can enter the sell by date for food and/or drink that is placed in the refrigerator so that the processor and/or computer 14, 16 can monitor when the food and/or drink should be used by or discarded.
Alternatively, the user can enter the purchase date as well as the type of food and/or drink and the processor and/or computer 14, 16 can estimate the remaining useful period for the food and/or drink. When unusual food is placed in the refrigerator, the processor or computer can go online to check multiple databases 20 or servers 22 to determine how long the food and/or drink can be expected to last. Additionally, the processor and/or computer 14, 16 (for simplicity, the term “processor 14” is hereinafter defined as meaning “any known processor and/or computer 14, 16”) can include algorithms and formulas to allow the expected period of usefulness (i.e., for how long the food and/or drink can be safely consumed) to be adjusted depending on the temperature of the refrigerator 12. Methods and apparatuses for entering data into a computer or processor are shown in U.S. patent application Ser. Nos. 10/614,091 and 09/901,595; each of which are hereby incorporated by reference herein as if fully set forth in their entirety.
A bar code reader 24 can be positioned in or by the refrigerator 12 to allow the food and/or drink data to be automatically collected by the refrigerator 12 and stored in the processor 14 when a user properly moves the food and/or drink past the bar code reader 24. The bar code reader 24 can be combined with any other data entry device 18 to allow multiple ways of entering food and/or drink data in the processor 14. One method and apparatus for scanning bar codes is shown in U.S. patent application Ser. No. 09/973,303 which is hereby incorporated by reference herein as if fully set forth in its entirety. Alternatively RFID tags placed on food and/or drink items can be used to provide data to the processor 14. This results in the “smart” refrigerator keeping a running inventory of all items in the refrigerator that is automatically updated when new items having RFID tags are inserted into or removed from the refrigerator 12.
In another preferred embodiment, an audible or visual indicator 26 can alert a user when food and/or drink in the refrigerator is nearing the end of its expected period of usefulness. The indicator 26 can be any combination of a light, an audible alarm, a synthesized voice, or text that is displayed on a display device 28 that is integrated with the refrigerator or attached to a connected or separate computer system 16. One method and apparatus for placing a display device on a refrigerator is shown in U.S. patent application Ser. No. 09/527,368 which is hereby incorporated by reference herein as if fully set forth in its entirety.
In another embodiment, the system 10 may also provide a print out of food and/or drink that is nearing the end of the expected period of usefulness. Another feature of the system 10 of the present invention is the ability of the processor 14 to access recipes that are stored on the processor 14 which include those food and/or drink items that are nearing the end of their expected period of usefulness. This makes using up leftover food and/or drink a fin exercise that can involve trying new and exciting recipes. Additionally, the system 10 can automatically access online databases 20 to update and/or download additional recipes. The user can also use the data entry device 18 to request recipes of a specific genre that use the food and/or drink items that are near the end of their expected period of usefulness. For example, the user can request that the processor 14 go online to find Chinese, Italian, Russian, Peruvian, barbeque, low-fat, and/or any other genre of recipes that incorporate those food and/or drink items that should be consumed in the near future. One method and apparatus for connecting and/or communicating between a processor and a computer network is shown in U.S. patent application Ser. No. 09/845,815 which is hereby incorporated by reference herein as if fully set forth in its entirety. A user can preferably contact the processor 14 by telephone or the Internet to identify a recipe and quantity of food to be prepared. For example, a user can access the processor 14 over the internet using a terminal, a personal digital assistant, PDA, email, or the like. Then, the processor 14 can determine whether all the needed ingredients are present in the refrigerator 12 or cupboards and can preferably automatically place an order with a selected supermarket for any missing ingredients. This allows one to plan last minute meals without having to inventory the contents of the refrigerator 12.
Additionally, a user can enter the type of food being prepared and the system 10 can alert the user to any food and/or drink items that need to be used which are nearing the end of their expected period of usefulness. For example, one may be making spaghetti and meatballs and not realize that some squash is located in the back of the crisper that is about to spoil. When beginning to cook, the user enters spaghetti and meatballs into the data entry device 18. When the processor 14 reviews the contents of the refrigerator 12, the processor determines that squash is about to go bad, and an audible or visual alert is provided to the user, letting him or her know that some squash in the refrigerator 12 may be a good addition to the spaghetti sauce. Additionally, the processor 14 can use remote data entry devices that are located in cupboards to keep track of ingredients that are stored in the kitchen outside of the refrigerator. This data can be used by the processor to alert a user as to additional potential recipes of interest. Alternatively, the processor can preferably provide a list of all items in the refrigerator 12 and/or cupboards with any desired associated information, such as quantity or expected expiration dates.
The system 10 also simplifies shopping. When it is time to go shopping, a user can enter into the processor that a trip needs to be planned and how long it may be before another subsequent shopping trip takes place. When this data is entered, the processor 14 reviews the contents of the refrigerator and prints out or displays a list of items that may need to be replaced prior to the subsequent shopping trip. This can prevent one from failing to buy milk because there is milk in the refrigerator (which is nearing the end of its expected period of usefulness) when one does not plan to return to the grocery store after the day's grocery shopping for two weeks (which may be a week after the milk would have expired).
The system 10 preferably includes an organization function that can be integrated with the processor 14 or other memory device that keeps track of upcoming events. For example, if one's child has to bring cupcakes to school on Tuesday and a dinner party is being held on a Friday, the processor 14 can provide alerts a predetermined amount of time in advance reminding the user that certain ingredients need to be obtained beforehand. To elaborate on the above example, when the user selects cupcakes, the processor 14 can check the Internet or stored recipes and provide sample recipes that can also be ranked based on the currently available ingredients; when selecting the dinner party icon, the processor 14 can suggest recipes based on current ingredients. Additionally, the processor can store preselected themes, such as a Mexican dinner, holiday dinners, religious meals, or a wine and cheese cocktail party theme, that can be used to facilitate menu generation.
The system 10 can also be integrated with cooking appliances, such as stoves, microwaves, toasters, coffee makers, and the like. For example, if a dinner is scheduled for 8 PM, the processor 14 can place an order at a supermarket for missing ingredients and automatically start preheating the oven while a user drives to the supermarket from the office.
The system 10 can be integrated with speakers and music players or online music databases to provide coordinated music during cooking and/or eating. For example, the processor 14 can identify Italian opera pieces over the Internet while a user is preparing Italian food so that the music can be played to complement the occasion. The processor 14 can preferably also look up decorating ideas that match the theme of a meal. For example, the type of table settings, centerpieces, wall decorations, or the like can be suggested by the processor 14. The processor 14 can also be linked with televisions or other monitors to provide coordinated pictures that relate to the culture from which a meal or theme originates.
Additionally, multiple systems 10 used by separate households can be linked to allow recipe and theme exchanges and the coordination of potluck type meals. For example, when planning a Mexican dinner, the systems 10 can use a common theme and select the individual dishes to be prepared by separate households based on maximizing the use of each household's current food inventory. Alternatively, if people are planning on cooking the entire meal at a single location, then the systems 10 can coordinate to advise guests which ingredients they should bring with them.
In addition, when a food and/or drink item is fully used, the data entry device 18 can be used to enter the information in the processor 14 to allow the automated generation of a shopping list. Additionally, the processor 14 can automatically place the order electronically with a supermarket server 30 or fax machine 30 so that the replacement of the necessary food and/or drink items is greatly simplified.
The system 10 also allows a user to remotely call/contact and access the system via a telephone or Internet connection to determine whether any food and/or drink items need to be purchased. This allows one to check while driving to the store or before leaving work. Additionally, the system 10 can be set so that the processor 14 sends emails or leaves voicemails at certain times of the day which can contain any pertinent information, such as recipes that incorporate food and/or drink items nearing the end of their expected period of usefulness so that one can make any necessary plans while still at the office or otherwise remote from the refrigerator 12.
It is recognized by those skilled in the art, that changes may be made to the above-described embodiments of the present invention without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but is intended to cover all modifications which are within the spirit and scope of the invention as defined by the appended claims.
