Abstract

A shipping container is used with methods for controlling shipment of a temperature controlled material so that once a customer order is initiated with a customer origin point and a customer destination the shipping container with a phase change material maintaining a sample chamber within the shipping container within a desired temperature range is shipped to the customer origin point where a temperature controlled material is loaded into the sample chamber and then the shipping container is shipped to the customer destination and then returned to a repurposing site and periodic location of the shipping container is tracked by use of a wireless location sensor associated with the shipping container during its shipment. The health of the shipping container, as well as the temperature of its sample chamber, can also be monitored, tracked, recorded and retrieved either during shipment or at the conclusion of a shipping cycle.

Claims

1. A method for tracking an object in transit, comprising:

providing a shippable object with an electronic tag that is configured to;

periodically measure at least one environmental condition experienced by the shippable object;

detect the presence of one or more networks accessible by the electronic tag; and

responsive to detecting at least one accessible network, transmitting information associated with the shippable object through the at least one accessible network,

wherein the transmitted information includes an identification of the shippable object and a history of at least one measurement of the environmental condition.

2. The method of claim 1, wherein presence of one or more accessible networks is detected after the shippable object is moved from a first location to a second location.

3. The method of claim 1, the electronic tag is further configured to determine when the shippable object has been moved based on a loss of connection with a previously accessible network.

4. The method of claim 1, wherein detecting the presence of one or more networks includes detecting a network accessible to the electronic tag while the shippable object is in transit between two physically remote locations.

5. The method of claim 4, wherein the electronic tag is further configured to identify a physical location of the shippable object associated with each measurement of the environmental condition, wherein the transmitting the information includes transmitting physical locations associated with measurements.

6. The method of claim 5, wherein the shippable object comprises a shipping container having a temperature controlled chamber and wherein the electronic tag comprises a wireless sensor.

7. The method of claim 6, wherein the at least one environmental condition includes a temperature of the temperature controlled chamber.

8. The method of claim 7, wherein the history of measurements comprises measurements obtained at a selected sample rate.

9. The method of claim 8, further comprising:

comparing the history of measurements with a set of expected measurements; and

generating an alarm when the history of measurements deviates from the set of expected measurements by more than a maximum tolerance value.

10. The method of claim 9, wherein the sample rate is adjusted based on a preselected variable and the physical location is identified based on identity of the at least one accessible network.

11. A tracking system for tracking an object in transit, comprising:

an electronic tag attached to a shippable object, the electronic tag including a processor;

a sensor configured to periodically measure at least one environmental condition experienced by the shippable object; and

a storage that maintains a history of measurements of the environmental condition,

wherein the electronic tag is configured to wirelessly communicate information associated with the shippable object upon detection of presence of a wireless network, the information including the history of environmental conditions and an identification of the shippable object.

12. The system of claim 11, wherein the wireless network is an unprotected network.

13. The system of claim 11, the information includes an indication that the shippable object has been moved, the indication being based on a loss of connection with a previously accessible network.

14. The system of claim 11, wherein the wireless network is accessed while the shippable object is in transit between two physically remote locations.

15. The system of claim 14, wherein the information identifies a physical location of the shippable object associated with each measurement of the environmental condition.

16. The system of claim 15, wherein the physical location is determined based on identity of the wireless network.

17. The system of claim 15, wherein the physical location is determined using a global positioning system.

18. The system of claim 11, wherein the history of environmental conditions comprises measurements obtained at a selected sample rate.

19. The method of claim 18, further comprising:

comparing the history of measurements with a set of expected measurements; and

generating an alarm when the history of measurements deviates from the set of expected measurements by more than a maximum tolerance value.
