Figure 3.

Examples of inaccurate wear/non-wear classification using differential temperature algorithms. The top graph shows internal and ambient temperature of three thermal events. The bottom graph shows data from the subject’s diary and the output of the two temperature algorithms (high = don, low = doff). The first two temperature events which were erroneously labeled as don time by the temperature algorithms, occurred during transportation of the RCW in a warm vehicle. The third event likely occurred because of loosely wearing the RCW in an office setting, such that, the leg was not in contact with the boot liner and hence was not near the internal temperature sensor.
