    • An electromechanical motor (1) comprises an object (2) to be moved, a vibrator beam (10), at least two protruding portions (12) attached to the vibrator beam, a normal force providing arrangement (40) applying a normal force (F) between the object and actuating ends (11) of the protruding portions for interaction with the object. The vibrator beam has vibrator beam electrodes (18A, 18B) for exciting at least one vibrator beam active volume (14) of electromechanically active material, enabling bending the vibrator beam perpendicular to a main extension direction of the vibrator beam and along the protruding portions (12). Control electronics (50), connected to the vibrator beam electrodes, is configured for providing resonance electrical signals causing the vibrator beam active volume to induce a resonant bending vibration and is further configured for providing quasi-static electrical signals causing a quasi-static motion of the actuating ends, superimposed on motion caused by the resonant bending vibration.

    • An electromechanical motor (10) comprises an object (20) to be moved, at least one electromechanical actuator (30) and a control electronics unit (90). The electromechanical actuator has actuator element(s) (40) with electromechanically active material and electrodes (44A-D, 45A-D) for exciting it. The actuator element is attached by a first end (46) to a support structure (50) and by a second end to a drive pad (60). The control electronics unit (90) is electrically connected to the electrodes of the electromechanical actuator. The control electronics provides first electrical signals, causing the drive pad to move in a non-resonant two-dimensional path. The control electronics is arranged for providing second electrical signals, causing the electromechanical actuator to move in a bending mode mechanical resonance. The contacting surface (62) of the drive pad is provided at a distance d from the centre line, larger than 0.1 micrometer times a ratio between the distance between the first and second end and the stroke of the bending mode.

    • The invention provides an antenna arrangement for a wireless communication system arranged to have at least one transmit mode and at least one receive mode, the arrangement comprising at least three directional antennas (601, 602, 603) in an antenna configuration. Each directional antenna is arranged to have an azimuthal radiation pattern shaped as a beam, each beam covering an angular sector, such that a combined radiation pattern of all beams in a first transmit mode is arranged to provide a full 360° omnidirectional coverage. By combining localization and polarization (P1, P2) of the directional antennas an omnidirectional radiation pattern substantially without null-depths in the azimuthal plane can be created when the radiation pattern of the directional antennas are combined. The invention also provides a corresponding method and a base station for communication with mobile terminals in a telecommunications network equipped with the antenna arrangement.
