Abstract: A method for determining a movement of a rotor of an electric motor, comprises supplying a drive signal to a drive coil of the electric motor, sensing a coil current of the drive coil, detecting current ripples of the sensed coil current caused by the rotor of the electric motor crossing ripple generating positions, inferring the movement of the rotor from the detected ripples, braking the motor by reducing the drive signal supplied to the drive coil from an initial signal value to zero according to a braking curve specifying a non-zero fall time during which the drive signal is reduced from the initial signal value to zero. The braking curve is adapted so that the rotor does not cross a ripple generating position after the drive signal has been reduced to zero.

Abstract: The techniques of this disclosure relate to a system for transmitting radio frequency signals. The system includes a controller in communication with a first device fixed within a first housing attached to an exterior of a vehicle. The system also includes a second device fixed within a second housing attached to the exterior of the vehicle. The controller determines whether the first housing and the second housing are in a first position or in a second position. When the first housing and the second housing are in the first position, the controller transmits first radio frequency signals via the first device and via the second device. When the first housing and the second housing are in the second position, the controller transmits second radio frequency signals via the first device and via the second device. The system improves an antenna coverage area of the first device and second device.
