  • Publication number: 20150181666
    Abstract: An arrangement and a method for controlling an array of light-emitting diodes includes a capacitor arranged in series with an electronic switch between one end of a first segment of the array and a constant-current source. A first terminal of the capacitor is connected to the one end and a second terminal of the capacitor is connected to the switch. The switch is connected to a control unit for control purposes.

  • Publication number: 20150156841
    Abstract: An arrangement and a method for controlling light-emitting diodes divided into segments of an array are provided. The second terminals of all segments in the array are connected to a constant current source via one respective switching element per terminal, resulting in formation of a number n of stages, each of which has an n-th segment and an associated n-th switching element. When the amplitude of the input alternating voltage is at zero volts, all switching elements in all n stages are through-switched. An n-th reference voltage and an node voltage measured at the second terminal of a segment in stage n+1 are compared, and if the n-th reference voltage is less than the node voltage, the switching element of the n-th stage is blocked.

  • Patent number: 6775767
    Abstract: A method for automatically assigning addresses in a bus system with a bus, a plurality of participating units connected to the bus and a control device for issuing control signals to the units also coupled to the bus, where each unit comprises an actuator and an actuator driving device for displacing the actuator along a displacement path defined by two end positions, is characterized by the following steps: storing, in the control device, operating data sets that, upon adjustment of the actuators from one end position to another end position, describe expected operation parameters of the actuator driving devices of the units, these set parameters being different for each actuator driving device, and storing address data that are also different and are assigned to the different set parameters; the control device causes the actuator driving devices of the units to move the respective assigned actuators to the one end position; the control device then causes the actuator driving devices of the units to move the
