Abstract: The invention is a method of monitoring the temperature to which an object has been exposed. The invention comprises combining a Time-Temperature Indicator (TTI) with an electronic monitoring device to determine whether the temperature to which the object has been exposed may have exceeded a predetermined threshold. The TTI device can be used to make a rapid initial determination as to the acceptability of the temperature history. The temperature history stored in the electronic monitoring device can be retrieved if visual inspection of the TTI indicates that the temperature history may possibly have exceeded the predetermined threshold. As a result, rejection of goods based on inaccurate TTI readings can be reduced or prevented, and the amount of time needed to retrieve data from an electronic monitoring device can be limited to only those circumstances where the initial visualization of the TTI indicates the possibility of an unacceptable temperature history.

After the mounting is converted to provide a moveable relationship, however, a temporary temperature excursion can cause the SMA portion to contract, providing a discernible change in the relationship between the sensing element and the body.

Abstract: An appliance temperature sensor for acquisition of usable data in a noisy environment collects a plurality of temperature readings in a buffer. It then screens that batch of data to determine whether or not its noise content is acceptably low before forwarding the data to a memory for use in subsequent appliance operations. Screening consists of computing the arithmetic mean and the variance of the readings of the batch at hand. If the variance is less than a predetermined threshold level, the mean of that batch of temperature data is forwarded to the memory for subsequent use. If the variance exceeds that predetermined threshold level, the data are expunged and not used. When the number of rejected contiguous batches of data exceeds a predetermined number, an alarm is provided to alert an operator that the system is noisy.

The measuring wheel determination of length is algebraically summed with the tension elongation and changes due to temperature to provide a more accurate indication of the depth measurement in the well bore.
