A tea pot comprises a receptacle having a pouring device and a handle on an opposite side. The seat mounting structure may include an inflation module, a linkage system, a sensor system, and a side airbag. In the invention, a less significant component of the binary drive signal, if appropriate after compensation in a low resolution digital-to-analog converter, is converted into an analog signal that is applied to a specific or a separate additional electrode of the digital phase modulator.
