Abstract: The disclosed examples relate to arranging graph data for display on a display device. One example provides, on a computing device, a method comprising determining one or more connected groups of nodes in directed acyclic graph data, for each connected group of nodes, determining a reachability from each node with no inputs to each of one or more nodes with no outputs to determine a plurality of initial node/terminal node pairs, and for each initial node/terminal node pair, determining a path from the initial node to the terminal node. The method further comprises initializing a grid based upon the determined paths, placing each node at a corresponding initial grid location, and placing edges between nodes based upon the determined paths to form an initial grid representation, modifying the initial grid representation via a cost function to form a modified grid representation, and outputting the modified grid representation for display.

Abstract: An on-board recording system for a vehicle is disclosed. The on-board recording system is configured to monitor data for errors. The on-board recording system includes one or more processors and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the processors, causes the on-board recording system to receive as input a data sequence including a plurality of frames. The frames are received and recorded by the on-board recorder at a corresponding assigned time offset and include a corresponding assigned message. The on-board recording system is further caused to determine a missing assigned message that has not been received at the corresponding assigned time offset. In response to determining the missing assigned message, the on-board recording system calculates a total length of time based on a number of missing assigned messages stored in the memory.
