Abstract: The present invention provides control of a synchronous machine with non-sinusoidal current-voltage profiles. The synchronous machine is controlled in a field-oriented coordinate system. In this case, the transformation between field-oriented coordinate system and stator-oriented coordinate system is effected by specific, adapted transformations which take account of the non-sinusoidal signal profiles during the driving of the synchronous machine, such that the latter correspond to current-voltage profiles progressing in a constant fashion in the field-oriented coordinate system. What is achieved thereby is that the non-sinusoidal current-voltage profiles need not be taken into account in any way in the design of the control system in the field-oriented coordinate system.

The second label indicates that the first object is depicted in the second image at the second position.

Abstract: In one embodiment, a computing system accesses a number of features extracted from one or more first images. The extracted features are associated with at least one object captured in the first images. The first images are captured by a camera associated with a vehicle. The computing system identifies, in a reference map, reference features matching one or more of the features extracted from the first images. The reference features are associated with the at least one object captured in the first images. The computing system generates, for the camera, a calibration model by comparing the identified reference features in the reference map and the features that match the one or more reference features. The calibration model is used to calibrate second images captured by the camera associated with the vehicle.

Abstract: The present invention provides control for synchronous machines in order to achieve an approximately constant torque irrespective of the load angle. The induced voltage of the synchronous machine rotating with a zero-current of the stator is first determined. Starting from the voltage plot of the induced voltage over the load angle, a current plot which achieves a constant torque irrespective of the load angle or any other default settings, can then be calculated. In particular, a non-sinusoidal current plot can also be calculated for non-sinusoidal plots of the induced voltage in the synchronous machine, in order to achieve desired settings that are as constant as possible irrespective of the load angle of the synchronous machine.

Abstract: The invention relates to a solenoid valve having an actuator body (17), in which a magnet coil (15) that interacts with a magnet core (16) is arranged and which interacts with an armature (14) that can be moved relative to the magnet core between two end positions and is acted upon by the spring force of an armature spring (13) in a movement direction pointing away from the magnet core (16). The magnet core and the armature have stop surfaces (18a, 18b) which are interrupted by a recess (29) that receives the armature spring. According to the invention, a solenoid valve is provided which is improved with respect to the function of the solenoid valve and the stress on the stop surfaces (18a, 18b) that causes wear. This is achieved in that the magnet core (16) and/or the armature (14) have/has a design (30, 31), in particular a spherical or toroidal design, which reduces the stress on the edges in the region of the stop surfaces (18a, 18b).
