Abstract: A method for collision avoidance of a motor vehicle with an emergency vehicle includes detecting surroundings of the motor vehicle using an optical detection arrangement, detecting wider surroundings of the motor vehicle using an acoustic detection arrangement, and detecting traffic users in the surroundings. The wider surroundings are investigated to detect a signal indicative of an emergency signal of the emergency vehicle, and a trajectory of motion for each of the detected traffic user is determined. If emergency signal is detected, a further investigation is undertaken to detect behavior that is indicative of a hazardous situation in the surroundings. If the behavior indicative of the hazardous situation detected, then the method also includes locating a position of the emergency vehicle and determining a trajectory of motion for the emergency vehicle based on the position of the emergency vehicle and the determined trajectories of motion of the detected traffic users.

Abstract: A method is provided for updating parking area information in a navigation system for a vehicle. The method includes the following steps: detecting a parking area by way of data received at least one device on at least one vehicle; determining information relating to the parking area which at least partially relates to characterizing characteristics of the parking area; analyzing the determined information in relation to an adequate characterization of the parking area; comparing the determined information with data of at least one database; and updating the database in the event of a deviation between the determined information and the data of the database.

Abstract: Methods for performing dose determination and cost function gradients in a radiation therapy are disclosed, which include: discretizing a volume-of-interest (VOI) into a set of voxels; identifying a set of beamlets which deposit dose contributions of radiation to the VOI, and each beamlet has a weight factor; transforming the dose contributions into a first domain, and transforming the weight factors into a second domain orthogonal to the first domain; calculate the local derivatives of a cost function of dose and cost function gradients with respect to the weights of the beamlets.
