Abstract

In some embodiments, apparatuses and methods are provided herein useful to monitoring temperature or movement of merchandise during and after transport of the merchandise. Some of these embodiments include systems for monitoring the temperature of merchandise items comprising: a temperature sensor disposed at or near one or more merchandise items; a control circuit operatively coupled to the temperature sensor, the control circuit configured to: read temperature measurements from the temperature sensor at predetermined time intervals; generate and encode a barcode with data representing a first temperature measurement; and update and encode the barcode with data representing the first temperature measurement and one or more subsequent temperature measurements; and an interface operatively coupled to the control circuit and configured to display the updated barcode.

Claims

1. A system for monitoring the temperature of merchandise items comprising:

a temperature sensor disposed at or near one or more merchandise items;

a control circuit operatively coupled to the temperature sensor, the control circuit configured to;

read temperature measurements from the temperature sensor at predetermined time intervals;

generate and encode a barcode with data representing a first temperature measurement;

update and encode the barcode with data representing the first temperature measurement and one or more subsequent temperature measurements corresponding to the temperature measurements taken by the temperature sensor at the predetermined time intervals;

the barcode being updated after each temperature measurement to add data representing a most recent temperature measurement and the updated barcode comprising data representing a plurality of sequential temperature measurements taken at the predetermined time intervals from the first temperature measurement to the most recent temperature measurement; and

an interface disposed at or near the one or more merchandise items and operatively coupled to the control circuit and configured to display the updated barcode, the interface comprising a display configured to periodically display barcodes on the same display at or near the one or more merchandise items and to overwrite a barcode with an updated barcode comprising data representing the plurality of sequential temperature measurements.

2. The system of claim 1, wherein each temperature measurement in the updated barcode is represented as a four digit value, one digit indicating a positive or negative value of the temperature measurement and the other three digits indicating an absolute value of the temperature measurement.

3. The system of claim 2, wherein the control circuit is configured to compare each temperature measurement to a predetermined temperature threshold and wherein each temperature measurement representation comprises an additional fifth digit indicating the number of instances that the predetermined temperature threshold has been exceeded.

4. The system of claim 1, wherein the control circuit is configured to compare each temperature measurement to a predetermined temperature threshold and wherein the updated barcode comprises data representing a sequence of digits indicating the amount each temperature measurement exceeded the predetermined temperature threshold.

5. The system of claim 1, further comprising a barcode reader configured to read the updated barcode locally at or near the one or more merchandise items to determine the data representing the plurality of sequential temperature measurements without transmission to a remote computing device.

6. The system of claim 1, further comprising a barcode reader configured to read the updated barcode and to transmit it to a computing device in communication with the barcode reader, wherein the computing device is configured to decipher the temperature measurements in the updated barcode and to create a task if one or more of the temperature measurements indicate that a predetermined temperature threshold was exceeded.

7. The system of claim 1, further comprising an actuator operatively coupled to the interface to cause the interface to display the updated barcode in response to the actuator.

8. The system of claim 1, further comprising a battery operatively coupled to the control circuit, wherein the control circuit is configured to update the barcode with data indicating a low power condition of the battery.

9. A method for monitoring the temperature of merchandise items comprising:

by a temperature sensor at or near one or more merchandise items, measuring temperature at predetermined time intervals;

by a control circuit, generating and encoding a barcode with data representing a first temperature measurement;

by a control circuit, updating and encoding the barcode with data representing the first temperature measurement and one or more subsequent temperature measurements corresponding to the temperature measurements taken by the temperature sensor at the predetermined time intervals;

the barcode being updated after each temperature measurement to add data representing a most recent temperature measurement and the updated barcode comprising data representing a plurality of sequential temperature measurements taken at the predetermined time intervals from the first temperature measurement to the most recent temperature measurement; and

by an interface disposed at or near the one or more merchandise items and operatively coupled to the control circuit, displaying the updated barcode, the interface comprising a display configured to periodically display barcodes on the same display at or near the one or more merchandise items and to overwrite a barcode with an updated barcode comprising data representing the plurality of sequential temperature measurements.

10. The method of claim 9, further comprising providing the control circuit and configuring it to receive temperature measurements according to a predetermined time interval.

11. The method of claim 9, further comprising determining whether one or more of the temperature measurements exceeded a predetermined temperature threshold.

12. The method of claim 11, further comprising determining information from the group consisting of:

the number of degrees, the frequency, and the length of time the one or more temperature measurements exceeded the predetermined temperature threshold.

13. The method of claim 9, further comprising:

scanning the updated barcode with a barcode reader; and

transmitting the updated barcode to a computing device in communication with the barcode reader; and

deciphering the temperature measurements in the updated barcode and creating a task if one or more of the temperature measurements indicate that a predetermined temperature threshold was exceeded.

14. The method of claim 9, further comprising:

providing a plurality of temperature sensors at predetermined locations in a storage area;

measuring temperature at the predetermined time intervals at the predetermined locations in the storage area;

by one or more control circuits, generating and encoding a plurality of barcodes with data representing a first temperature measurement at each predetermined location; and

by one or more control circuits, updating and encoding the plurality of barcodes with data representing the first temperature measurement and one or more subsequent temperature measurements at each predetermined location.

15. The method of claim 14, further comprising increasing or decreasing cooling to one or more of the predetermined locations in response to the temperature measurements.

16. The method of claim 9, further comprising:

scanning the updated barcode of the one or more merchandise items at the time of delivery by a delivery vehicle;

continuing to measure temperature at predetermined time intervals following delivery;

continuing to update and encode the barcode with data representing temperature measurements following delivery; and

scanning the updated barcode following movement to a storage area.

17. The method of claim 9, further comprising:

generating and encoding a first updated barcode with a first barcode device;

scanning the first updated barcode at the time of delivery by a delivery vehicle;

measuring temperature at predetermined time intervals following delivery;

updating and encoding a second barcode with data representing temperature measurements following delivery with a second, different barcode device; and

scanning the updated second barcode following movement to a storage area.

18. A system for monitoring the movement of merchandise items, the system comprising:
