The time constant, τ, was extrapolated from the data to be approximately 50 seconds. In the frequency domain, this translated to a bandwidth of 0.003 Hz. Therefore, following Nyquist criterion (sampling at least twice the bandwidth of the original signal), the minimal sampling in the active mode to avoid aliasing in the reconstruction of temperature is 0.006 Hz or 166 seconds.[18] To ensure accurate temperature reconstruction in the

active mode, the monitor was programmed to sample every 60 seconds for 5 minutes, before returning to the idle mode. this website The subjective reporting of compliance by the participants in this study served as the control to compare the results of the objective data recorded by the compliance monitor. A Pearson correlation

coefficient was employed to evaluate the relationship between objective and subjective elapsed times. Means and standard deviations of objective and subjective elapsed times were determined along with the percent nightly usage of the test appliance by each participant over the period of time in which he/she was in possession of the appliance. Finally, the percentage of participants reporting various adverse effects while wearing the MRD was examined. By using appropriate sampling rates at transition periods (insertion/removal), usage time can be determined without the need for calibrating

GDC0199 monitors for absolute temperature accuracy. Mathematica Software (Wolfram Research, Champaign, IL) was used to filter the temperature data based on slopes and time constant to extract the objective insertion and removal times (Fig 4A). Filtering the data in this manner is more robust against false positives than filtering Interleukin-3 receptor by a temperature threshold (Fig 4B). Objective usage times by each participant were compared to the times indicated in their treatment journals (Fig 4C). The correlation between subjective times as recorded by the participants and objective times as recorded by the monitor was 0.9985 (Fig 5). The mean objective wearing time, as detected by the compliance monitor, was 6.6 ± 1.6 hours/night. The mean subjective wearing time, as recorded by the participants, was 6.5 ± 1.5 hours/night (Fig 6). The mean usage of the MRD by participants in this study was 68.7%, with a range of 24% to 100% (Fig 7). Table 1 shows the percentage of participants reporting adverse effects while wearing the MRD. Modern processors operate at the lowest power by remaining in a deep sleep mode as long as possible. Awakening a processor to take a data point draws a fixed amount of charge from its power source. In the case of an intraoral monitor, the power source is a battery, which can only carry a certain amount of charge.
