A physiological monitoring system collects electrocardiogram (“ECG”) data from through monitoring sensors via a sensor interface. A machine learning model identifies characteristics of the ECG data that may be attributable to a cardiovascular device used by the patient. At least one normal ECG template for the individual patient is created and continuously updated by the machine learning model. Abnormal ECG data sets are analyzed using knowledge-based beat classifiers to identify specific arrhythmias. A data structure stores responses to the specific arrhythmias based on their likely effects on the patient. For example, the response to a dangerous arrhythmia may be an emergency alarm, while the response to a temporary arrhythmia quickly corrected by the patient's pacemaker may be a non-urgent message or a note to file.

In addition, an aggregation signal (STEV, TWA) is generated, which is an averaging or accumulation of several target gas signal values. If an aggregated value is between a smaller and a larger aggregation threshold (STEVlow, TWAlow, STEVhigh, TWAhigh), an aggregation warning is issued. If the aggregated value is greater than the larger aggregation threshold (STEVhigh, TWAhigh), an aggregation alarm is issued.

ILLUMINATION DEVICE AND ILLUMINATION PROCESS WITH AUTOMATIC SHADING COMPENSATION
An illumination device (100) and an illumination process are capable of illuminating a surface. A control unit (10) captures an illuminance specification and controls the light sources (a.1, b.1, c.1) of the illumination device in such a way that the maximum illuminance achieved on the surface is equal to the illuminance specification. Each light source can be controlled independently of any other light source. Several distance meters (dm, dm.2, . . . , dm.6) measure the respective distance between themselves and the illuminated surface. The control unit detects the event that an object (AO) is shading an area of the surface and causes this shading to be at least partially compensated. For this purpose, the control unit increases the maximum illuminance of unshaded light sources. Preferably, the maximum illuminance of light sources that are redundant or partially redundant to shaded light sources and are not themselves shaded is increased.
