A data signal having a single polarity is outputted from a data driver of an in-plane switching type liquid-crystal display unit. The internal combustion engine andor the electric motor can introduce torque into a transmission downstream in the drivetrain, and a separating clutch is provided between the internal combustion engine and the electric motor. The apparatus allows collecting dynamical measurements using a set of multiple frequencies of interest at once, in one measurement instead of sequential, one frequency in a time; measurements. Additionally, methods are provided for forming films of a charge-transport layer on an active layer of an optoelectronic device. The support leg can be rotated from a storage position substantially in the same plane as the U-shaped support member to a use position substantially perpendicular to such support member plane. The output of each sensor including a sensor class probability vector based on each sensor’s classification database is input to a fusion engine which estimates a base class probability vector based on the sensor class probabilities output by the sensors and a preconfigured base database including base classes.
