  • Patent number: 7990073
    Abstract: A method for operating a fluorescent lamp which is connected to a series resonant circuit with a resonant circuit inductance and a resonant circuit capacitance. The method includes applying an excitation AC voltage at an excitation frequency to the series resonant circuit using a half bridge circuit, which has an output to which the series resonant circuit is coupled, and which has a first and a second switch which are alternately switched on and off on the basis of a frequency signal. A current flowing through the resonant circuit is monitored for the presence of a critical operating state. The switched-on times of the first and second switches are shortened in comparison to switched-on times which are predetermined by the frequency signal, upon detection of a critical operating state.

  • Patent number: 7986222
    Abstract: A tire position identification system and method include a transmitter that is configured to send an initiation signal. A receiver is configured to receive the initiation signal and attenuate the initiation signal until the initiation signal is within a first predetermined range of a reference signal.
