Abstract

A food storage apparatus comprises a container (140) for containing a food item, and a cover (142) for covering an opening of the container (140). A first electrical component (144) is associated with the container (140). A second electrical component (146) is associated with the cover (142). The first electrical component (144) communicates with the second electrical component (146) to monitor the food item.

Claims

1. A food storage apparatus comprising:

a container for containing a food item, the container having an opening;

a first electrical component associated with the container;

a cover for covering the opening of the container; and

a second electrical component associated with the cover;

wherein the first electrical component is in electrical communication with the second electrical component to monitor the food item.

2. The food storage apparatus of claim 1 wherein the first electrical component and the second electrical component communicate when the cover seals the opening of the container.

3. The food storage apparatus of claim 1 wherein the cover includes a first at least one electrical contact and the container includes a second at least one electrical contact to provide an electrical coupling between the first electrical component and the second electrical component when the cover seals the opening of the container.

4. The food storage apparatus of claim 1 wherein one of the first electrical component and the second electrical component includes a sensor, and wherein another of the first electrical component and the second electrical component includes an indicator.

5. The food storage apparatus of claim 1 wherein one of the first electrical component and the second electrical component includes at least one of a receiver, a transmitter, a processor, and a memory, and wherein another of the first electrical component and the second electrical component includes an indicator.

6. The food storage apparatus of claim 1 wherein one of the first electrical component and the second electrical component includes at least one of a receiver, a transmitter, a processor, and a memory.

7. The food storage apparatus of claim 1 wherein the container is sized for carrying by an individual.

8. The food storage apparatus of claim 1 wherein the container has a capacity less than or equal to 10 liters.

9. The food storage apparatus of claim 1 wherein at least one of the first electrical component and the second electrical component includes one of a temperature sensor, a humidity sensor, and an acidity sensor.

10. A method of monitoring a food item comprising the steps of:

determining a time duration that the food item is outside of a storage place; and

generating an indication based on the time duration.

11. The method of claim 10 wherein the storage place refrigerates the food item.

12. The method of claim 10 wherein the step of determining the time duration includes the steps of:

determining a first time at which the food item is removed from the storage place;

determining a second time at which the food item is returned to the storage place; and

determining the time duration based upon the first time and the second time.

13. The method of claim 12 wherein the step of determining the first time includes the steps of:

prior to the first time, establishing communication between a tag communicating device and an electronic tag associated with the food item when the food item is within the storage place; and

detecting a loss of communication between the tag communicating device and the electronic tag when the food item is removed from the storage place;

wherein the first time is based upon a time at which the loss of communication is detected.

14. The method of claim 13 wherein the step of determining the second time includes reestablishing communication between the tag communicating device and the electronic tag after the food item is returned to the storage place, wherein the second time is based upon a time at which communication is reestablished.

15. The method of claim 10 wherein the time duration is determined using an electronic tag associated with the food item.

16. The method of claim 15 wherein the electronic tag is included in a food storage apparatus for containing the food item.

17. The method of claim 16 wherein the indication is generated by an indicator associated with one of the food storage apparatus and the storage place.

18. A system for monitoring a food item, the system comprising:

a receiver which receives a signal associated with a temperature proximate to the food item;

a processor which determines a time duration that the temperature is beyond a predetermined temperature threshold; and

an indicator to generate an indication based upon the time duration.

19. The system of claim 18 wherein the signal is received from a food storage apparatus for containing the food item, the food storage apparatus having a temperature sensor to sense the temperature proximate to the food item.

20. A system for monitoring a food item, the system comprising:

a processor to determine a first time at which the food item is removed from a storage place, to determine a second time at which the food item is returned to the storage place, and to determine the time duration based upon the first time and the second time; and

an indicator to generate an indication based upon the time duration.

21. A food storage apparatus for monitoring a food item, the food storage apparatus comprising:

a container for containing the food item; and

an electronic tag which communicates with a tag communicating device to determine a time duration that the food item is outside of a temperature controlled storage place.

22. The food storage apparatus of claim 21 further comprising an indicator which generates an indication of the time duration.

23. The food storage apparatus of claim 21 wherein the electronic tag communicates with the tag communicating device to determine the time duration by determining a first time at which the food item is removed from the storage place, determining a second time at which the food item is returned to the storage place, and determining the time duration based upon the first time and the second time.

24. A method of monitoring a food item, the method comprising the steps of:

establishing communication between a tag communicating device and an electronic tag associated with the food item;

detecting a loss of communication between the tag communicating device and the electronic tag;

reestablishing communication between the tag communicating device and the electronic tag;

determining a time duration between a first time at which the loss of communication is detected and a second time at which communication is reestablished; and

generating an indication based upon the time duration.

25. The method of claim 24 wherein communication between the tag communicating device and the electronic tag is established when the food item is placed to a storage place, wherein the loss of communication between the tag communicating device and the electronic tag is detected when the food item is removed from the storage place, and wherein communication between the tag communicating device and the electronic tag is reestablished when the food item is returned to the storage place.

26. A system for monitoring a food item, the system comprising:

a tag communicating device to establish communication with an electronic tag associated with the food item, to detect a loss of communication with the electronic tag, and to reestablish communication with the electronic tag, the tag communicating device having a processor to determine a time duration between a first time at which the loss of communication is detected and a second time at which communication is reestablished; and

an indicator responsive to the processor to generate an indication based upon the time duration.

27. The system of claim 26 wherein communication between the tag communicating device and the electronic tag is established when the food item is placed to a storage place, wherein the loss of communication between the tag communicating device and the electronic tag is detected when the food item is removed from the storage place, and wherein communication between the tag communicating device and the electronic tag is reestablished when the food item is returned to the storage place.
