Abstract: The invention relates to a home automation system and a method for controlling the same. In order to stably control a continuing concerted adjustment action of a continuously variable parameter by means of few and low-sized commands in order to avoid overloading of a low-data rate network while providing means for fast and unobtrusive correction of failures due to missed commands, it is provided a method for controlling a wireless home automation system, the home automation system being arranged as a network comprising at least one controller and a plurality of devices, wherein the method comprises the steps of sending a start command from the controller to a group of devices comprising an action type and a transaction ID and sending a stop command from the controller to the devices comprising the transaction ID and a controller counter.

Abstract: A device according to the invention for writing information to an information carrier (1) includes conversion means (7) for converting symbols in an information signal (SINFO) into pulse sequences in a control signal (STR). The device further includes a transducer (10) for generating a physically detectable pattern on the information carrier (1) in response to the control signal (STR). The conversion means (7) include assignment means (702) for assigning properties of the pulse sequences to symbols in the information signal (SINFO). These properties include the duration and the magnitude of pulses in the pulse sequence. The conversion means (7) further include at least one counter (711) for supplying a count signal (TC1) after a time interval, which counter is coupled to the assignment means (702). The conversion means (7) further include a controllable delay line (761) coupled to the at least one counter (711), for delaying the count signal (TC1), and to the assignment means (702).

Abstract: Picture display device comprising a plurality of electron transport ducts or transporting electrons in the form of electron currents, and selection electrodes for withdrawing each electron current at predetermined locations from its transport duct and for directing said current towards a luminescent screen. The selection electrodes are driven by a selection driver comprising integrated driver circuits having outputs which are DC-coupled to the selection electrodes and are cascaded as regards their power supply voltages in such a way that they apply both selection pulses and transport (bias) voltage to the selection electrodes.

Abstract: A display device often includes a correction circuit for correcting a position error which is caused by the fact that the deflection signals are not (any longer) in conformity with the video signals to be displayed. This is caused, inter alia by the fact that the deflection coils and the display tube are not ideal. By providing the display device with a waveform generator generating a (line deflection) reference signal and by causing this reference signal to traverse the same "signal path" as the video signal, variations in the delay etc. can be corrected. Both the video signal and the reference signal are stored in a memory and read from the memory under the control of the correction circuit. Inputs of the correction circuit receive the (line deflection) reference signal delayed via the memory and a signal related to the (real) line deflection. With reference to these input signals, the correction circuit applies a (read) clock signal to the memory.
