System for remotely monitoring changes in condition

摘要

A system for remotely monitoring change in condition. A condition indication device can include an indication area and an identification area. The indication area can include one or more of a freeze/thaw indicator, heat temperature marker or high temperature indicator. A reader reads information from the indication area and the identification area. Information is forwarded from the reader using a remote network to a remote recognition device. In one embodiment, the reader takes a picture of the indicator device and the picture is forwarded as information to the remote recognition device. A conductivity changes to solutions and/or emulsions together with color changes in the remote indicating device can remotely monitor the change in condition. The information obtained at the remote recognition device can be used to determine a status, location and time for a point in transit or storage of the condition indication device.

主权项

1. A system for remotely monitoring changes in condition comprising:
a condition indication device including an indicator and an identification, said indicator includes a color indicator and a conductivity measuring indicator, said color indicator changing a color of the color indicator if there has been a change of condition, said conductivity measuring indicator has a different value if there is a change of condition; a reader, said reader obtaining first information directed to said indicator and said identification; and a remote recognition device, receiving said first information and determining a status of said condition indication device.
