摘要： The invention relates an electrical device for providing an output depending on an electrical input. The electrical device (1) is adapted to provide a constant output, if the electrical input is in a first electrical input range, and a dependent output, if the electrical input is in a second electrical input range, wherein the dependent output depends on the electrical input. The output can therefore remain constant, even if the electrical input, which is preferentially a DC grid voltage, fluctuates within the first electrical input range. Moreover, in the second electrical input range the output can be controlled by just controlling the electrical input like the DC grid voltage, without necessarily requiring an additional control construction of the electrical device. A resistance against fluctuations of the electrical input and a controllability of the output can therefore be realized in a relatively simple way.

摘要： Cables (1, 2) comprise first and second conductors (1, 2) for transporting signals to be picked-up in contactless manners. At first/second locations (3, 4), the first and second conductors (1, 2) are at first/second distances from each other. The first locations (3) are neutral locations where the conductors (1, 2) are parallel. The second locations (4) are pick-up locations. The second distances are larger than the first distances. Pick-up devices for picking-up signals in a contactless manner from the cables (1, 2) comprise parts for defining minimum values of the second distances. These parts may comprise core-parts, such as center ends (10) of E-shaped magnetic cores further comprising outer ends (11, 12) and backs (13). Methods for installing pick-up devices comprise steps of at second locations (4) increasing a distance between the first and second conductors (1, 2) from a value of the first distance to a value of the second distance. Twin-cables (1, 2) or twin-lead-cables (1, 2) are suited well for allowing signals to be picked-up in contactless manners.

摘要： Organic light emitting diode arrangement Organic light emitting diode arrangements (1) are, to protect them against an effect of a switch-on, provided with circuits (31-36) for, during a first time interval that follows a switch-on, limiting a current through the organic light emitting diode arrangement (1) more and for, during a second time interval that follows the first time interval, limiting the current less. The circuit (31-36) may be passive such as a negative temperature coefficient resistor (31) or a series inductor (32) possibly with a freewheel diode (40) or may be active such as a switchable resistor (33) that is not bridged during the first time interval and that is bridged during the second time interval or a switchable resistor that is bridged in response to a detection of a value of the current exceeding a threshold value or such as a part of a converter (63) that is controlled in response to a detection of a value of the current.
