摘要： A method for detecting the level of a liquid in a container. The method includes applying a predetermined voltage to a level measuring electrode, disposed within the container, for a predetermined first period of time; then, discontinuing the application of the voltage and waiting a predetermined second period of time; and then measuring an electrode voltage at the level measuring electrode.

摘要： A supplementary device, such as a charging, cleaning and/or diagnosis device, for a small electric device, such as an electric hair cutting or hair removal apparatus or an electric toothbrush, but particularly for an electric shaving apparatus, includes an arrangement to detect whether it is connected electrically and/or magnetically to the small electric device, and an arrangement to discriminate between different types of small electric device. This arrangement monitors an electric and/or magnetic quantity prevailing at the connection of the supplementary device. A method for detecting the presence of an electric and/or magnetic connection between said devices includes monitoring an electric and/or magnetic quantity prevailing at the connection of the supplementary device.

摘要： The apparatus includes a method of transmitting data between a small electric appliance such as an electric hair cutting apparatus, an electric toothbrush or a household appliance, and a supplementary electric appliance connectible therewith such as a charging, cleaning or diagnostic device, as well as to appliances suitably configured for this purpose. The supplementary appliance supplies to the power supply connection of the small electric appliance an electric current, an electric voltage or an electric and/or magnetic field which is modulated with a corresponding data signal by the small electric appliance or by the supplementary appliance, depending on the desired direction of data transmission. Demodulation is effected in the receiving appliance.
