If sensors detect deviations (i.e. prediction errors), a controller (or regulatory system) must be engaged in order to restore accurate predictions.
In this paper, a dynamic analytical model, namely sensor charge output deviation method is proposed to identify a delamination embedded in a cantilever laminated composite beam bonded with isolated piezoelectric actuator and sensor patches.
Furthermore, as an alternative design, the FH-TENG has been integrated into a bearing pedestal, which can not only harvest mechanical energy from the shaft radial movement, but also be applied as a self-powered axis deviation sensor.
The PGCS used fault detection settings regarding 1) correlation of sensor signals, 2) deviation of sensor glucose (SG1 and SG2) from the mean (SG), 3) mutual difference in rate of glucose change (direction of trend), 4) loss of sensor signal, RF, or Bluetooth connectivity, and 5) insulin delivery limits.
Comparing two fused systems showed that the mid-level fusion was more effective than the low-level one, where in the best fused systems (integration of all three sensors), the standard deviation ratio (SDR) values for Ea and MTf were improved by 11.2%and9.1%1%, respectively, and the satisfactory results for both Ea (R2p = 0.926, SDR = 3.07) and MTf (R2p = 0.841, SDR = 2.51) were obtained.
The deviation of sensor signal is continuously evaluated to ensure that both sensors track within predetermined parameters.
Closed-loop therapy significantly reduced mean overnight glucose levels by 0.9mmol/ll (p < 0.001), with no difference in glycaemic variability, as measured by the standard deviation of sensor glucose.
We also calculated the values of our non-enzymatic glucose sensor for stability, standard deviation (SD) of stability, and reusability (see Table 1).
It can be found that, in WDMA-based UWB sensor networks with timing deviation, our orthogonal waveforms considerably outperform other existed UWB orthogonal signals.
This happens when the degradation is due to internal system wears and tears and it is too difficult to have direct sensor readings of its deviation from normal values.
