Data compression is continuously optimized using frequency-based dictionary lookup tables for communication between a transmitter in a vehicle and a receiver. In a transmitter, first and second frequency-based dictionary lookup tables are provided. The transmitter receives a data block and compresses it using the first table. Using the data block, the second table is updated and a difference between a compression efficiency of the first table and a compression efficiency of the second table for the data block is calculated. The compressed data block is transmitted to the receiver.

METHOD FOR GENERATING 3D REFERENCE POINTS IN A MAP OF A SCENE
A method of complementing a map of a scene with 3D reference points including four steps. In a first step, data is collected and recorded based on samples of at least one of an optical sensor, a GNSS, and an IMU. A second step includes initial pose generation by processing of the collected sensor data to provide a track of vehicle poses. A pose is based on a specific data set, on at least one data set re-coded before that dataset and on at least one data set recorded after that data set. A third step includes SLAM processing of the initial poses and collected optical sensor data to generate keyframes with feature points. In a fourth step 3D reference points are generated by fusion and optimization of the feature points by using future and past feature points together with a feature point at a point of processing. This second and fourth steps provides significantly better results than SLAM or VIO methods known from prior art, as the second and the fourth steps are based on recorded data. Wherein a normal SLAM or VIO algorithm only can access data of the past, in these steps, processing may also be done by looking at positions ahead, by using the recorded data.

METHOD FOR PROTECTING THE TIME SYNCHRONIZATION IN A NETWORK AGAINST UNAUTHORIZED CHANGES
The time synchronization of a network is protected against unauthorized changes to the grandmaster clock of a base time domain by monitoring the physical communication interfaces of a network device for arrival of messages relating to time synchronization. If the messages relating to time synchronization apply to the initially set-up and synchronized base time domain, a check is performed to determine whether the messages relating to time synchronization announce a new grandmaster clock having better clock parameters than those of the present grandmaster clock. If so, a virtual base time domain is started by the network device. If the verification reveals that the proposed new grandmaster clock is trustworthy or valid, the network device discontinues the virtual time domain, updates its stored information concerning the grandmaster clock and, from this time onward, sends messages relating to time synchronization that are based on the new clock parameters to the network.
