Several transmission embodiments selectively communicate rotary drive to an orbiting scroll to achieve capacity modulation. The ends of an interconnection having 4 transmission conductors and a return conductor distinct from the reference conductor are each connected to a termination circuit. The lamellae prevent glare in plane S and in surrounding planes and thereby allow the luminaire to meet the Unified Glare Rating. A probability that the patient is an LQT1 carrier or an LQT2 carrier is determined based on a regression model which takes into account the first ECG parameter and the second ECG parameter.
