Abstract: A fault protection circuit for an alternator is provided for preventing faults such as a prolonged full-field condition in the alternator. The fault protection circuit includes a safety switch that is opened when the alternator output voltage becomes too high, as may occur during a full-field condition caused by an electrical short, or when some other fault is detected within the alternator. The opening of this safety switch disconnects a supply voltage feeding an excitation current control switch. The excitation current control switch normally adjusts an excitation current provided to a rotor in the alternator, in order to regulate a voltage output from the alternator. By providing a safety switch that disconnects the supply voltage for the rotor excitation in the alternator, the alternator output voltage may be prevented from reaching excessive levels that may damage devices in an electrical system and a battery coupled to the alternator.

Abstract: A method for determining malfunction is provided. The method includes receiving a 1D or 2D luminance image of a scene from a time-of-flight based 3D-camera. The luminance image includes one or more pixels representing intensities of background light received by an image sensor of the 3D-camera. The method further includes receiving a 2D optical image of the scene from an optical 2D-camera and comparing the luminance image to the optical image. If the luminance image does not match the optical image, the method additionally includes determining malfunction of one of the 3D-camera and the 2D-camera.

Abstract: A monitoring component may select a reference area, associated with an environment of an imaging system, based on a three-dimensional (3D) image obtained by the imaging system. The monitoring component may determine a reference image corresponding to the reference area. The reference image may be determined based on design data associated with the environment of the imaging system. The monitoring component may perform, based on the 3D image and the reference image, a functional safety check to determine a functional safety status associated with the imaging system. The monitoring component may selectively provide a signal based on the determined functional safety state.
