Abstract: A method is proposed for adjusting an actuator (300) of a positioning system (100). The positioning system (100) has an electronically commutated actuator drive (200) which is coupled to the actuator (300), wherein the actuator drive (200) has a permanent magnetic rotor (210), wherein the rotor (210) has a first shaft (212) which extends along a pole axis (290) of the rotor (210). The actuator drive (200) additionally has an electronically commutated stator (230), wherein the stator (230) can be energized using a space phasor (260), wherein the space phasor (260) has an electric phase and an amplitude, wherein the space phasor (260) is aligned with respect to the first shaft (212) of the rotor (210) around a difference phasing.

Abstract: An actuator (1), which is developed for converting an electronic signal into mechanical motion, with a breakaway function for rectifying a malfunction, such as jamming, wherein the means is provided to supply an increased electric voltage to the actuator (1) if the breakaway function is activated.

Abstract: A method for adjusting coolant temperature in an internal combustion engine (2), whereby the coolant circuit thereof contains an electrically driven coolant pump (3) and an electrically controllable bypass valve (4). If the setpoint value of the coolant temperature changes in an abrupt manner, the rotating speed of the coolant pump (3) rises during the short interval in order to reduce the dead time required for adjustment. A Smith controller, which takes into account dead times of the system, is used to regulate the bypass valve.

Abstract: An actuator has an actuating element and an actuating drive with an electromagnet with a coil. An armature, which can be coupled to the actuating element, can move between a first contact surface on the electromagnet and a second contact surface. An initial current or a higher holding current flows through the coil until a time at which the armature plate is reliably in contact with the contact surface of the electromagnet. An operating state of high-speed current reduction is then selected, wherein the opposite polarity of the supply voltage in comparison to the initial current flow is applied to the coil. A holding current then flows through the coil.

Abstract: For detecting and separating the shadow of moving objects in a sequence of digital images, a sequence of background images is first determined from a sequence of images, this sequence of background images containing only the non-moving image background of the sequence of images but not the moving objects. Object edges are then extracted from the sequence of images in that in each case an edge gray-value image is determined for each image of the sequence of images and for each respective corresponding background image of the sequence of background images. Using vertical or horizontal projection of these edge gray-value images, corresponding vertical or horizontal edge histograms are determined in each case for the edge gray-value images.
