    Abstract: An optical system for monitoring a vehicle driver's eye gaze includes a first illumination source and a second illumination source for emitting light towards the driver's eye, a lens, and an image sensor for detecting an image, wherein the lens is configured to direct light reflected by the driver's eye to the image sensor, and wherein a distance between the second illumination source and an optical axis of the lens is larger than a distance between the first illumination source and the optical axis. Further, a method for monitoring a vehicle driver's eye gaze with an optical system is disclosed.

    Abstract: The present disclosure discloses a computer-implemented method for a pitch angle recognition of a steering column in a vehicle. In aspects, the computer-implemented method includes measuring first acceleration data using a first acceleration sensor and measuring second acceleration data using a second acceleration sensor. The computer-implemented method further includes determining drift data of at least one of the first acceleration sensor and the second acceleration sensor based on the first acceleration data and the second acceleration data. Additionally, the computer-implemented method includes determining a pitch angle of the steering column based on the drift data, the first acceleration data, and the second acceleration data.
