摘要： Before a washing machine is switched over to a very high spin speed in the spin program of the washing machine, the existing imbalance due to irregular distribution of laundry in the drum should be checked. If the imbalance is too strong, the spin program should be interrupted if there is a threat of excessively high bearing forces to be expected. The fluctuation in rotary speed, which may have a high frequency due to the drum speed, and of the power consumption of the washing machine motor measured downstream of the direct current intermediate circuit prior to the feed thereof into the inverter for producing the rotary field in the motor. There, the vector product of the current and the voltage for imbalance measurement by determining power is blocked off from mains network interference effects by the high capacitance of the direct current intermediate circuit.

摘要： In the wireless telegram communication (28) from data-generating, unidirectionally communicating terminal devices (12) by way of primary radio sections (10) and by way of subsequent bidirectionally operating data collectors (13) of a radio network (11) to a data-documenting master data collector (14), a memory and selection expenditure governed by redundancy as a consequence of multiple connections by way of the primary radio sections (10) is avoided and nonetheless very reliable telegram communication (18) is achieved with simplified data collectors (13) if distribution criteria such as for example reception field strength-dependent quality information (22) is currently detected and stored in data collectors (13) for primary radio sections (10) from terminal devices (12). In dependence on the instantaneous distribution criteria for each terminal device (12) the master data collector (14) implements a quasi-stationary association with one and only one of the data collectors (13) for the subsequent telegram communications (18), until for example periodically or in an event-controlled manner a new association of a terminal device (12) is again implemented with one and only one, possibly a different one of the data collectors (13). The data collectors (13) also operate with each other as relay stations (25) for forwarding the data telegrams (18) to the master data collector (14) and are equipped, to prevent telegram doublets occurring on different routes, with a barrier against the same data telegram (18) being read out a plurality of times.

摘要： In spite of the enormous market-originating price pressure, even large-scale domestic appliances can be fitted with LCD displays for user guidance. The expensive universal driver circuits (LCD controller ICs) with their many unused functionalities are replaced by simple logic gate circuits synchronized by a host processor for the exchange of image data between the V-RAM and the display, for cyclically successively counting through the pixels (that is to say columns) per image line and the lines per image representation of the display. As now an address in the V-RAM and thus a matrix position in the image of the display corresponds to each counting position per image, and the memory is not occupied with image data continuously but only in a corresponding section. This however is not a problem because large image data memories are available very inexpensively in comparison with an expensive LCD controller IC.

摘要： An electromagnetic valve has a magnetic coil and a movable element coupled to a valve element. The magnetic coil, when excited, conveys the movable element in one direction to move the valve element from its initial position into its active position. A control circuit for the electromagnetic valve has a current source for optionally supplying current to the magnetic coil and a measuring device for measuring a voltage level of the magnetic coil and/or a current level through the magnetic coil. A monitoring unit which is connected to the measuring device establishes a switching state of the electromagnetic valve corresponding to the position of its valve element based on the intended current supply state of the current source and the current and/or voltage characteristic measured by the measuring device and, if appropriate, determines a fault state of the current supply and/or the electromagnetic valve.

摘要： An operating device contains a cover plate having an opening, a rotatable operating element having an operating head on the cover plate, and a shaft running through the opening. Behind the cover plate and at a distance therefrom, there is a circuit board having an opening through which the shaft extends. The operating device includes a tube element which has a hollow-cylindrical base body that runs, between the cover plate and the shaft of the operating element, at least partially through the opening of the cover plate, and a radial inner side that forms, between the tube element and the shaft of the operating element, an inner flow channel that runs through the opening of the cover plate and past the opening of the circuit board, to protect the circuit board against extraneous substances which may enter the operating device through the opening of the cover plate.
