RFID—controlled smart range and method of cooking and heating
First Claim
1. A method of heating a vessel using a range having an RFID reader/writer reader, wherein the vessel includes an RFID tag and a temperature sensor, the method comprising the steps of:
- (a) reading a set of heating instructions from an external storage medium separate from said vessel and selected from the group consisting of a recipe card and a food package, wherein the heating instructions include a sequence of one or more heating steps, with at least one of the heating steps including a desired temperature;
(b) detecting the vessel and identifying vessel information;
(c) reading the actual temperature of the vessel from the RFID tag;
(d) determining a temperature differential between the desired temperature of the set of heating instructions and the actual temperature; and
(e) controlling heating of the vessel based at least in part upon the temperature differential.

Abstract
A system and method for providing multiple cooking modes and an ability to automatically heat cooking vessels and other objects using RFID technology, and an ability to read and write heating instructions and to interactively assist in their execution. An induction heating range is provided with two antennas per hob, and includes a user interface display and input mechanism. The vessel includes an RFID tag and a temperature sensor. In a first cooking mode, a recipe is read by the range and the range assists a user in executing the recipe by automatically heating the vessel to specified temperatures and by prompting the user to add ingredients. The recipe is written to the RFID tag so that if the vessel is moved to another hob, into which the recipe has not been read, the new hob can read the recipe from the RFID tag and continue in its execution.

16. A method of heating a vessel using an induction range having an RFID reader/writer, wherein the vessel includes an RFID tag and a temperature sensor, the method comprising the steps of:
-
(a) reading a set of heating instructions from an external storage medium separate from said vessel and selected from the group consisting of a recipe card and a food package, wherein the heating instructions include a sequence of one or more heating steps, with at least one of the heating steps including a desired temperature; (b) detecting the vessel and writing the set of heating instructions to the vessel RFID tag; (c) reading the actual temperature of the vessel from the RFID tag; (d) determining a temperature differential between the desired temperature of the set of heating instructions and the actual temperature; and (e) controlling heating of the vessel based at least in part upon the temperature differential. - View Dependent Claims (4, 17)

21. A method of heating a vessel (28) using a range (22) having an RFID reader (52), wherein the vessel (28) is on said range (22) and the vessel (28) includes an RFID tag (24) and a temperature sensor (26) operably coupled with the RFID tag (24) so that information about the actual temperature of the vessel (28) sensed by said sensor (26) is received by said RFID tag (24), the vessel RFID tag (24) storing information confirming the presence of said RFID tag (24) and said temperature sensor (26), the method comprising the steps of:
-
(a) loading heating instructions onto said reader (52) from a recipe card, food package, or other item separate from the vessel (28), including one or more heating steps including a desired vessel regulation temperature; (b) heating said vessel (28) by (i) reading the temperature of the vessel (28) from the vessel'"'"'s associated RFID tag (24);
(ii) determining a temperature differential between said desired temperature and the vessel temperature; and
(iii) controlling the heating of said vessel (28) based upon the temperature differential and said heating instructions,said heating step being carried out only if said reader (52) detects the presence of a suitable vessel (28).
