Abstract: A method of operating a plurality of communications nodes in a 10BASE-T1S Ethernet network. The plurality of communications nodes are configured to implement a physical layer collision avoidance, PLCA, process. At least two of the communications nodes are candidate beacon generators. The method comprises: for each of the at least two candidate beacon generators, determining a time delay since a last received beacon, comparing the determined time delay with a threshold value associated with the candidate beacon generator, and if the time delay exceeds the threshold value then setting that candidate beacon generator as an in-use beacon generator; and the in-use beacon generator transmitting a beacon to define the start of a PLCA cycle, thereby triggering a transmit opportunity for each of the other communication nodes.

Abstract: A system includes a processor and a non-transitory computer-readable medium storing machine instructions that cause the processor to perform a first fast Fourier transform (FFT) on received radar data to obtain a range-antenna data array and to perform a second FFT on the range-antenna data array to obtain a range-Doppler-antenna data cube. The processor performs peak detection on the range-Doppler-antenna data cube based on object information to obtain a subset that includes confirmed peaks and candidate peaks. The processor performs angle of arrival calculations for the subset of the range-Doppler-antenna data cube, and filters candidate peaks in the subset to obtain a point cloud representative of an environment. In some implementations, the confirmed peaks are detected based on a default threshold value, the candidate peaks are detected based on at least one adapted threshold value, and the at least one adapted threshold value is determined based on the object information.

Abstract: The present invention relates to a network device comprising: a first input interface, a first output interface, and a second output interface, wherein the network device is configured to change from a first state, referred to as a time state, to a second state, referred to as a spatial state, and vice versa, wherein the network device is configured to generate each of a first output message and a second output message based on a first input message, wherein the network device is configured to transmit, in the time state, both, the first output message and the second output message, offset in time either via the first output interface or second output interface, and wherein the network device is configured to transmit, in the spatial state, the first output message via the first output interface and the second output message via the second output interface. The present invention also relates to a communication system comprising the network device and to a method for the network device.
