摘要： An electromechanical actuator 10 is disclosed, having drive elements (14a–d) movable in two dimensions and connected to an actuator backing (12). The actuator backing (12) is made of a material being ferromechanically inactive. Furthermore, the joint between the drive element (14a–d) and the actuator backing (12) is stiff and highly stable. This is achieved by use of an irreversible joint made e.g. by thermoset plastic glues, diffusion bonding or co-sintering. Co-sintering is to prefer. The actuator backing (12) material is selected to be stiff, preferably having a stiffness above 70 GPa and more preferably above 100 GPa, and having a high heat conductivity, preferably above 5 W/mK and more preferably above 10 W/mK, Electrodes (22) are preferably integrated in the actuator backing to increase stiffness as well as improving the heat conductivity. The drive elements (14a–d) are preferably covered (28, 26), at least at the driving surface, by heat-conducting material.

摘要： In an electromechanical motor, elongated electromechanical drive elements are mechanically and preferably also electrically attached to a carrier. A spring is arranged to apply a force on the electromechanical drive element by pressing the backside of the carrier at a pivot point. The carrier is allowed to pivot around the pivot point around an axis parallel to a the element elongation. The electromechanical drive element is thereby suspended in a floating manner. The electromechanical drive elements are arranged to present a bending motion having strokes perpendicular to the elongation. The pivot point, the mechanical joint between the carrier and the electromechanical drive element, and preferably also a nodal point of bending motions of the electromechanical element are situated at a common plane perpendicular to the element elongation. In one embodiment, the electromechanical drive element is provided with metallizations to which the carrier is soldered.

摘要： An electromechanical motor (1) has a driving element (30) comprising two electromechanical sections (32, 34) extended substantially parallel to a driving surface (14) of a body (10) to be moved. The electromechanical sections (32, 34) are rigidly supported by a backbone portion (22) of a stator (20) at a first end (38). An link member (40) having a single actuating portion (42), which by its interaction with the driving surface (14) of the body (10) moves the body (10), is attached between respective second ends (36) of the electromechanical sections (32, 34). The electromechanical sections (32, 34) are excitable in a vibration mode having strokes substantially perpendicular to the direction of motion (12). A portion of the link (40) or the joints (46, 54) between the link member (40) and the electromechanical sections (32, 34) have a bending stiffness in the direction of the strokes that is significantly lower than the bending stiffness of the electromechanical sections (32, 34) themselves.

摘要： According to the present invention, electromechanical motors are driven in such a way that contact portions of driving elements (10) are moved along smooth trajectories. The velocity is varied, the average velocity being lower during the time when the element (10) is in contact with a moving object (22) than during the contact free time. Preferably, the main displacement velocity component is non-negligible when switching between sets of elements (10). When stopping the motor, the actuating sets of elements (10) are brought into a voltage-free condition, one set at a time. The contact portions of the elements (10) are lapped with such an accuracy, that the normal force applied between the moving object and the stator (2) is large enough to cause elastic deformations of the stator (2) that are in the same order of magnitude or larger than the accuracy of the lapping.

摘要： A mechanically simple dual-frequency (or wide band) quadrifilar helix antenna (1). It includes four helix shaped radiating elements (2-5) where each helix element consists of two or more parallel helices (2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b) of different lengths that are in galvanic contact at, or close to, the feeding point (2c, 3c, 4c, 5c). The four feeding points (2c, 3c, 4c, 5c) of the helix elements (2-5) are located at the bottom of the helix, meaning that the feedings of the helix elements are located at the end (6) of the helix pointing in the direction opposite to the direction of its main radiation.

摘要： A sight apparatus has a day-sight part, a night-sight part and a filter which quenches the visible light so that the night-sight part in the form of an IR sight can be used during the daytime as well. In order to improve use of the night-sight under daylight conditions the filter has characteristics which quench visible light having wavelengths outside the wavelengths of blue light and is arranged in the beam path for the incoming visible light.
