摘要： The present invention provides a method for predicting a remaining lifetime of an electrical component of an electrical circuit, the electrical circuit being part of a building management device. The method comprises: estimating (S1) two or more estimated temperatures of the electrical component by using a trained machine learning model of the electrical component that is trained based on training data. Further, the method comprises: generating (S2) a temporal course of temperature of the electrical component based on the two or more estimated temperatures; and computing (S3), based on the temporal course of temperature of the electrical component, an indicator for the remaining lifetime of the electrical component. The present invention also provides a method for predicting a remaining lifetime of an electrical circuit being part of a building management device.

摘要： An isolated multiple-output power supply with a function of detecting the presence or absence of a load at an output port is disclosed. The power supply includes a first voltage source for providing a first voltage at a first node; a first diode having a cathode coupled to the first output port, and an anode coupled to the first node for receiving the first voltage; a second voltage source for providing a second voltage at a second node; a second diode having a cathode coupled to a second output port, and an anode coupled to the second node for receiving the second voltage; and a bridging circuit having two terminals respectively connected to the first and the second output ports. When the load is not present at the first output port, the bridging circuit pulls up an output voltage at the first output port to reverse bias the first diode.
