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.

First claim

What is claimed is:

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; 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.

2 . The system of claim 1 , wherein the barcode is updated after each temperature measurement to add data representing the most recent temperature measurement.

3 . The system of claim 1 , wherein the updated barcode comprises data representing a plurality of sequential temperature measurements taken at the predetermined time intervals from the first temperature measurement to a last temperature measurement.

4 . 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.

5 . The system of claim 4 , 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.

6 . 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.

7 . The system of claim 1 , wherein the interface comprises an e-ink interface configured to display barcodes and to overwrite a barcode with an updated barcode.

8 . 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.

9 . The system of claim 8 , wherein the computing device 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.

10 . 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.

11 . 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.

12 . 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; and by a control circuit, updating and encoding the barcode with data representing the first temperature measurement and one or more subsequent temperature measurements.

13 . The method of claim 12 , wherein the updated barcode comprises data representing a plurality of sequential temperature measurements taken at the predetermined time intervals from the first temperature measurement to a last temperature measurement.

14 . The method of claim 12 , further comprising displaying the updated barcode on an e-ink interface.

15 . The system of claim 12 , further comprising providing the control circuit and configuring it to receive temperature measurements according to a predetermined time interval.

16 . The method of claim 12 , further comprising determining whether one or more of the temperature measurements exceeded a predetermined temperature threshold.

17 . The method of claim 16 , 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.

18 . The method of claim 12 , 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.

19 . The method of claim 12 , 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.

20 . The method of claim 19 , further comprising increasing or decreasing cooling to one or more of the predetermined locations in response to the temperature measurements.

21 . The method of claim 12 , 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.

22 . The method of claim 12 , 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.

23 . A system for monitoring the movement of merchandise items, the system comprising:
a sensor disposed on a merchandise item measuring movement; a control circuit operatively coupled to the sensor, the control circuit configured to:
read measurements from the sensor at predetermined time intervals;
generate and encode a barcode with data representing a first sensor measurement;
update and encoding the barcode with data representing the first sensor measurement and the one or more subsequent sensor measurements; and
an e-ink interface operatively coupled to the control circuit and configured to display the updated barcode.

24 . The system of claim 23 , wherein the sensor comprises one o
