Abstract

A cooking temperature sensor having a controller including a thermal imaging camera which identifies at least one food item in a cooking environment. A display is in communication with the controller and the controller transmits data representative of the at least one food item for display. A selection is received in connection with the data and associates a temperature with the at least one food item. The controller monitors a thermal value of the at least one food item and generates an alert indicative of when the temperature is reached for the at least one food item.

Claims

1. A grill temperature sensor comprising:

a controller including a camera coupled thereto, the camera identifying thermal properties of at least one food item on a grill;

a display in communication with the controller, the controller transmitting data representative the thermal properties of the at least one food item for display;

a selection received in connection with the data and associating a temperature with the at least one food item;

the controller monitoring a thermal value of the at least one food item and generating an alert indicative of when the temperature is reached for the at least one food item.

2. The device of claim 1 wherein the data is an image.

3. The device of claim 1 wherein the selection is an area containing at least two food items.

4. The device of claim 1 wherein the selection is indicative of food type and doneness.

5. The device of claim 4 wherein the doneness is based on a scale between rare and well done.

6. The device of claim 1 further comprising:

a housing having the controller, camera and display coupled thereto such that the grill temperature sensor is a hand holdable device.

7. The device of claim 6 further comprising a trigger positioned on said housing such that activation of said trigger causes a thermal image to be taken by the camera for processing by the controller.

8. The device of claim 1 wherein the alert indicative of when the at least one food item is suggested to be flipped.

9. The device of claim 1 wherein the controller is configured to communicate wirelessly with a mobile device having said display thereon.

10. A cooking temperature sensor comprising:

a controller;

a camera in communication with said controller, the camera identifying thermal properties of at least one food item in a cooking environment based at least in part on infrared energy emitted by the at least one food item as measured by the camera;

said controller configured to receive signals from the camera, the signals indicative of the thermal properties;

a selection received by the controller to associate a temperature with the at least one food item; and

software executing on the controller which determines a thermal value of the at least one food item based on the thermal properties identified by the camera, said software generating an alert indicative of when the temperature is reached for the at least one food item.

11. The device of claim 10 wherein the selection is indicative of food type and doneness.

12. The device of claim 10 wherein the thermal value is determined at least based on an emissivity of the at least one food item.

13. The device of claim 12 wherein the selection indicates a food type having an emissivity associated therewith.

14. The device of claim 10 wherein said software identifies the at least one food item by determining a boundary associated therewith, the boundary being determined based on identifying a first temperature associated with a grilling surface and comparing the first temperature to the thermal value wherein the boundary is defined around a perimeter of the at least one food item where the first temperature is at least 1.5 times the thermal value.

15. The device of claim 10 wherein based on the selection, the temperature is determined at least in part based on a thickness of the at least one food item.

16. The device of claim 11 wherein the selection is indicative of a final temperature and the temperature is calculated based on an estimated carry-over temperature change such that the alert is generated when the temperature is lower than the final temperature.

17. A method of measuring a temperature of one or more food items in a cooking environment comprising the steps of:

capturing with an imaging device an infrared energy associated with an area of the cooking environment;

identifying the one or more food items based on a drop in the infrared energy being measured in a closed loop pattern within the area;

associating a temperature with at least one of the identified one or more food items; and

generating an alert when the temperature is reached.

18. The method of claim 17 wherein the drop is at least 1.5 times a measured temperature adjacent to the closed loop pattern over a distance of one inch or less.

19. The method of claim 17 wherein the drop is at least 1.5 times a measured temperature adjacent to the closed loop pattern over a distance of half an inch or less.

20. The method of claim 17 wherein the drop is at least 1.5 times a measured temperature adjacent to the closed loop pattern over a distance of a quarter inch or less.
