    Abstract: Circuito de alimentación para alimentar una señal de tensión y una señal de corriente a una fuente (6) de luz, comprendiendo el circuito de alimentación al menos un conmutador (22, 32, 42, 52) y un controlador (21, 31, 41, 51) para controlar el al menos un conmutador (22, 32, 42, 52), en el que mediante tal control se reduce un valor de al menos una componente de frecuencia de un residuo armónico de un espectro de potencia de la fuente (6) de luz, caracterizado porque la al menos una componente de frecuencia del residuo armónico comprende al menos una primera componente de frecuencia a una frecuencia igual a dos veces una frecuencia base de al menos una de una señal de tensión adicional y una señal de corriente adicional que se originan desde una fuente (11) de CA, en el que mediante tal ajuste del residuo armónico se reduce el centelleo visible en la luz que se origina desde la fuente (6) de luz sin usar un condensador electrolítico para reducir este centelleo visible.

    Abstract: A method and a circuit arrangement for the operation of a high-pressure gas discharge lamp (HID [high intensity discharge] lamp or UHP [ultra high performance] lamp) is described, which lamp is particularly suitable for illuminating projection displays with sequential color rendering (for example LCOS or SCR-DMD systems) with a pulsatory lamp current. Artefacts in the color rendering are avoided through the generation of at least one compensation pulse of a given amplitude and a given timing and through superimposition thereof on the lamp current.

    Abstract: A circuit and a method for operation of a gas discharge lamp includes a switching transformer having a switch, a converter, inductor and a controller in a control loop for measuring a lamp voltage and setting a desired power. The switching transformer further includes a second control loop used for adjusting the switching transformer to individual lamp conditions.

    Abstract: The invention relates to a method and a device ( 1 ) for data transmission in a power supply network (power line communication). The device ( 1 ), preferably centrally located in a distribution box ( 6 ), is equipped with transceivers ( 3, 4, 5 ), each one of which is connected to a phasing line ( 11, 12, 13 ) of the power supply network, from which it can receive data, and to which it can transmit data. The transceivers are coupled via a control unit ( 2 ), wherein the control unit ensures that the data received from a phasing line can be transmitted, prepared, on at least one other phasing line. Hereby, a re-transmission on all phasing lines with the same transmission power, or a re-transmission matched to the particular signal strengths or the addressees of the data, can take place.

    Abstract: A projection system for image representation includes a display, a lamp, and a sensor for generating a sensor signal for monitoring and compensating changes in the luminous flux provided by the lamp. To achieve a monitoring of the light quantity actually incident on the display, an optical component is arranged in a light path between the lamp and the display. The optical component allows a first light component to pass through and reflects a second light component such that one of the light components is directed at the display and the other light component is directed at the sensor arranged outside the light path. A sensor signal generated in this manner renders it possible to compensate for fluctuations in the luminous flux provided by the lamp through the control of a lamp driver in an effective.

    Abstract: The invention relates to a method and a server ( 1 ) for implementation of central standby functions in an (in-home) network with devices ( 11 - 16 ) connected thereto. The standby server ( 1 ) contains a central processor ( 3 ), a mass memory ( 4 ) and interfaces ( 2, 5, 6 ) for the network connection. When one of the devices ( 11 - 16 ) is shut down, it sends corresponding information and where applicable data to the server ( 1 ) whereupon the latter takes over the standby functions for the device. In particular the server ( 1 ) can temporarily store data directed to the device as long as this is switched off, or pass on with time delay data to be transmitted by the device. Centralization of the standby functions in a special server reduces the energy consumption and improves the speed of data transmission.
