Abstract

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.

Claims

1. A system for remotely monitoring changes in condition comprising:

a condition indication device including an indicator and an identification;

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.

2. The system of claim 1 wherein said identification is a bar code.

3. The system of claim 1 wherein said reader obtaining second information of one or more of a location of the condition indication device or a time of said reader obtaining said first information.

4. The system of claim 1 wherein said reader includes a camera for inputting said first information and said remote recognition device performs pattern recognition on said first information.

5. The system of claim 1 wherein said remote recognition device includes storage for storing said first information.

6. The system of claim 1 wherein said indicator provides an irreversible visual indication of a condition selected from the group consisting of a room temperature to a freeze event, cold temperature to a freeze event, freezing temperature to a thaw event, room temperature to greater than about 37.8 degrees C. and a temperature of about −

20 degrees C. to greater than about 37.8 degrees C.

7. The system of claim 1 wherein said indicator comprises a housing;

a solution or a first surface, at least a portion of said first surface being of a first color;

a first reactant located in the solution or on said first surface within said housing;

a capsule containing a liquid and a second reactant, said capsule being located within said housing;

wherein said liquid freezes at a first threshold temperature and expands upon freezing whereby said capsule fractures from the liquid expansion and wherein said first and said second reactants combine on said first surface to produce a pigment of a second color upon mixing, said first and said second colors being different.

8. The system of claim 7 further comprising a second capsule located within said housing and optionally a third reactant;

wherein the formulation of said second capsule comprises a component that melts at a second threshold temperature and wherein said second capsule contains said second reactant or said optional third reactant;

wherein when said optional third reactant is present, said third and first reactants combine to produce a pigment of a third color upon mixing, said third color being different from said first color.

9. The system of claim 1 wherein said indicator is a color change indicator and further comprising a heat temperature marker, said first information comprising color change information, said reader obtaining heat temperature marker information from said heat temperature marker.

10.
