    Abstract: The invention relates to a coupling module ( 1 ) via which communication becomes possible between different electronic appliances of an (in-home) network ( 30 ). To this end, the coupling module ( 1 ) can be expanded in modular fashion with transmitter and receiver modules ( 20 - 27 ), which in each case create a network interface with the electronic appliances, with the associated transmission protocol in each case. The coupling module ( 1 ) may preferably independently detect the connected appliances, and pass on incoming information to the particular addressee in the appropriate protocol.

    Abstract: In order to improve the efficiency of a driver circuit for controlling upper and lower switching means (T3, T4) for converting a direct voltage Ud into a clocked output voltage Ua for a resonant converter with a high-voltage section (HT) for controlling the upper switching means (T3) and a low-voltage section (NT) for controlling the lower switching means (T4), which switch the switching means (T3, T4) on alternately to one another, the switch-on phases of the switching means (T3, T4) being separated from one another by dead-time phases, there is provided a first circuit section which controls the duty cycle Dtein3 of the upper switching means (T3) as a function of the duty cycle Dtein4 of the lower switching means (T4), and receives control signals from the low-voltage section (NT) exclusively during the duty cycle Dtein4 of the lower switching means (T4).

    Abstract: In order to improve the efficiency of a driver circuit for controlling upper and lower switching means (T 3 , T 4 ) for converting a direct voltage Ud into a clocked output voltage Ua for a resonant converter with a high-voltage section (HT) for controlling the upper switching means (T 3 ) and a low-voltage section (NT) for controlling the lower switching means (T 4 ), which switch the switching means (T 3 , T 4 ) on alternately to one another, the switch-on phases of the switching means (T 3 , T 4 ) being separated from one another by dead-time phases, there is provided a first circuit section which controls the duty cycle Deltatein 3 of the upper switching means (T 3 ) as a function of the duty cycle Deltatein 4 of the lower switching means (T 4 ), and receives control signals from the low-voltage section (NT) exclusively during the duty cycle Deltatein 4 of the lower switching means (T 4 ).

    Abstract: The circuit has a lamp driver (110) for providing a regulated lamp current to operate the HID lamp (322) in response to a control signal and an intensity sensor (130) for producing and outputting a sensor signal representing the light output at the sensor position. A high pass filter (140) provides the control signal by filtering the sensor signal. Independent claims are also included for the following: an electrical circuit and an image projector with an HID lamp.

    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.
