Abstract: A communication device comprises a receiver including at least two receive antennas and configured to receive at least one reference signal of a plurality of reference signals, each reference signal being transmitted from at least one base station at a predefined reference signal transmission time; a controller configured to switch between at least two receive configurations of the at least two antennas during a reception period of the at least one reference signal; and a signal quality determiner configured to determine a parameter indicative of a first signal quality of the received reference signal for each receive configuration.

Abstract: An electric motor for a vehicle includes a stator, a rotor and a plurality of independent bridge drivers. Each bridge driver supplies a portion of current to the electric motor. There may be a phase shift between each independent bridge driver. Optionally, each bridge driver delivers current at a slew rate that is different from each other independent bridge driver.

Abstract: The invention relates to a road-building machine, comprising a drivable chassis (1) on which a driver's cab (3) having a control panel (2) is provided. A canopy (5) that is fixed to the chassis by at least one support (6) is arranged above the driver's cab, wherein at least one support (6) is adjustably arranged on the chassis (1) such that the canopy (5) can be lowered for a transport position and raised for a working position. For a working position with reduced set-up height, the lowered canopy (5) forms a free space (9) for an operator in the region of the control panel (2) of the driver's cab (3), wherefore a canopy section covering the control panel (2) is designed such as to be movable relative to the chassis (1).
