System and method for controlling temperature indicators
First Claim
1. A temperature indicator stick system configured to indicate a predetermined temperature when exposed to the predetermined temperature, the temperature indicator stick system comprising:
- a housing having an interior configured to receive a temperature indicator stick;
a drive roller supported by the housing to engage the temperature indicator stick, the housing including a first opening configured to allow the temperature indicator stick to advance out from and retract into the housing and a second opening through which the drive roller extends to engage the temperature indicator stick;
wherein the temperature indicator stick includes a keyed shape and the first opening has geometry matched to the keyed shape; and
wherein rotation of the drive roller causes at least one of retraction and advancement of the temperature indicator stick to and from the interior of the housing.

Abstract
A system and method for controlling a temperature indicator stick includes a housing having an interior configured to receive the temperature indicator stick configured to indicate a predetermined temperature through a physical change or a chemical when exposed to the predetermined temperature. A roller drive is supported by the housing to engage the temperature indicator stick. Accordingly, rotation of the drive roller causes a retraction or advancement of the temperature indicator stick to and from the interior of the housing. Additionally, the housing and temperature indicator stick may include a key system to keep the temperature indicator stick in a substantially fixed rotational position with respect to the housing as the temperature indicator stick advanced from and retracted into the housing.

10. A temperature indicator stick system configured to indicate a predetermined temperature, the temperature indicator stick system comprising:
-
a housing extending along a longitudinal axis to form a substantially hollow interior along the longitudinal axis; a drive mechanism supported by the housing; a temperature indicator stick arranged within the interior of the housing and having a keyed shape extending along the longitudinal axis; an opening formed at one end of the longitudinal axis to provide access to the hollow interior and having a geometry configured to mate with the keyed shape formed on the temperature indicator stick; wherein actuation of the drive mechanism causes at least one of retraction and advancement of the temperature indicator stick to and from the interior of the housing through the opening; and wherein the geometry of the opening holds the temperature indicator stick, through the keyed shape, in a substantially fixed axial position with respect to the housing as the temperature indicator stick is moved to and from the interior of the housing through the opening. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A temperature indicator stick configured to indicate a predetermined temperature, the temperature indicator stick comprising:
-
an elongated stick extending from a first end to a second end to form a shaft extending therebetween, the elongated stick formed of a matter configured to indicate a predetermined temperature through at least one of physical and chemical change when exposed to the predetermined temperature; and a keyed shape including at least one of a protrusion and a trough, wherein each of the at least one of a protrusion and a trough are extending in a substantially straight line along the shaft between the first end and the second end.
