Abstract

A communication system includes multiple nodes of a time-sensitive network and a scheduler device. At least one of the nodes is configured to obtain a first signal that is represented in a frequency domain by multiple frequency components. The scheduler device generates a schedule for transmission of signals including the first signal within the time-sensitive network. The schedule defines multiple slots assigned to different discrete frequency sub-bands within a frequency band. The slots have designated transmission intervals. The nodes are configured to transmit the first signal through the time-sensitive network to a listening device such that the first signal is received at the listening device within a designated time window according to the schedule. At least some of the frequency components of the first signal are transmitted through the time-sensitive network within different slots of the schedule based on the frequency sub-bands assigned to the slots.

Abstract

A system and method examine positional data signals onboard a vehicle to identify one or more variations in positioning data of the positional data signals. The system and method identify inaccurate positioning data in the positional data signals based on the one or more variations in the positioning data that are identified.

Abstract

A communication system includes one or more processors that determine a communication risk value for each path of multiple paths within a time-sensitive network. The multiple paths are defined by multiple nodes and links that communicatively connect the nodes. The processors establish a redundant path of the paths that bypasses a low reliability path of the paths. The redundant path includes at least one different link or node from the low reliability path. The processors control the time-sensitive network to communicate duplicate copies of a data frame in parallel along both the redundant path and the low reliability path to increase a likelihood that the data frame is received at a listening device from a publishing device within a designated time window according to a schedule of the time-sensitive network.

Abstract

An inverter system is provided that includes switches that alternate between closed and open states to conduct or block conduction, respectively, of electric current through the switches and switch controllers that control operation of the switches between the closed and open states. In a first operating mode, the controllers control operation of the switches to convert direct current into a single, common phase of an alternating current from a same phase output from each of the switches to power a higher-demand load of a powered system with the single phase of the alternating current. In a second operating mode, the controllers control operation of the switches to convert the direct current into multiple, different phases of the alternating current to power a lower-demand load of the powered system with the multiple, different phases of the alternating current. Each of the switches outputs a different phase of the multiple phases.
