Abstract: The present invention describes carbazole, dibenzofuran, dibenzothiophene and fluorene derivatives which are substituted by electron-deficient heteroaryl groups, in particular for use as triplet matrix materials in organic electroluminescent devices. The invention furthermore relates to a process for the preparation of the compounds according to the invention and to electronic devices comprising these compounds.

Abstract: The application relates to compounds having functional substituents in a specific spatial arrangement, to devices comprising same, and to the preparation and use thereof.

Abstract: An apparatus configured for wirelessly communicating in a wireless communications network includes a wireless interface configured for wireless communication and a controller configured for controlling a beam pattern of the wireless interface and at least one communication parameter of the wireless interface. The apparatus is configured for receiving a locking signal indicating a request for locking at least a part of the beam pattern and the at least one communication parameter. The controller is configured for locking at least the part of the beam and the at least one communication parameter responsive to the locking signal.

Abstract: An apparatus including a processor unit configured to provide a first high-definition map, a sensor unit configured for providing sensor data representing an environmental condition in a periphery of the apparatus and a receiver unit configured to receive data representing a second high-definition map. The processor unit is configured to fuse the second high-definition map and the sensor data so as to provide the first high-definition map. The apparatus further includes a transmitter unit configured for transmitting a result of fusing the second high-definition map and the sensor data, and includes a command generator unit configured to generate a command signal representing a vehicle control command for a vehicle carrying the apparatus based on the first high-definition map.
