US Patent 11679200 Closed loop control and signal attenuation detection

Methods, system and devices for monitoring a plurality of parameters associated with a closed loop control operation including continuously monitoring a physiological condition and automatic administration of a medication, detecting a signal level associated with the monitored physiological condition deviating from a predetermined threshold level, retrieving the medication level administered associated with a time period of the detected signal level, applying the retrieved medication level to the detected signal based on a predefined predictive model to generate a predictive signal, and comparing the detected signal to the predictive signal to determine whether a condition associated with the detected signal level is present are provided.
