Abstract: Disclosed are techniques for improving an advanced driver-assistance system (ADAS) by pre-processing image data. In one embodiment, a method is disclosed comprising receiving one or more image frames captured by an image sensor installed on a vehicle; identifying a position of a skyline in the one or more image frames, the position comprising a horizontal position of the skyline; cropping one or more future image frames based on the position of the skyline, the cropping generating cropped images comprising a subset of the corresponding future image frames; and processing the cropped images at an advanced driver-assistance system (ADAS).

Abstract: A sound system for a locomotive mounts a loudspeaker line array for broadside firing forward from the vehicle. Additional loudspeakers are installed on the locomotive for projecting sound to the sides. A control system applies drive signals to the loudspeakers of the line array with the control system providing phase adjustment of drive signals applied to each loudspeaker of the line array to control side to side directional steering of a projected sound beam. The control system includes an automated, location dependent sub-system for selecting beam width and directional steering of a projected sound beam.

Abstract: Procedure and system for driving a vehicle required to travel repeatedly over the same path, in which procedure at least some elements of the vehicle are operated in accordance with prerecorded information.According to the invention, the information relates to the operations to be performed on or by such elements in relation to the position of the vehicle on its path; and the elements are operated on the basis of such information in the light of the vehicle's instantaneous position with a correction for instantaneous vehicle speed and the response time of the elements.
