Abstract: An embodiment method of detecting an arc fault includes communicating a power line signal, including a communication signal modulated on an alternating current power signal, over a power line. The communication signal is communicated according to a power line network protocol. A power spectrum of the communication signal includes a first frequency band and a second frequency band different from the first frequency band. In accordance with the power line network protocol, a power of the communication signal in the first frequency band is attenuated in comparison to the power of the communication signal in the second frequency band. The method further includes performing arc fault detection on the spectral portions of the power line signal that are within the first frequency band.

Abstract: A powerline communication system includes a plurality of rail segments. Each of the rail segments is electrically isolated from other rail segments, and each receives power from a rail segment power supply. At least one cart operates on the rail segments. The cart has a powerline communications controller. Each rail segment has a current state defined by how many and which carts are operating on the rail segment. A central coordinator is coupled to each rail segment and configured to execute a channel estimation using a sounding protocol on its rail segment. The central coordinators store tone maps associated with the possible states of its rail segment, and possibly its adjacent rail segment. A main controller communicates with each central coordinator to direct the state and future state of its segment so that tone maps and network keys can be managed by the CCo in advance of an imminent state change. The main controller or CCo may also execute channel estimation using a sounding protocol and cause updated tone map information to be sent to each central coordinator in advance of an imminent state change.

Abstract: In accordance with an embodiment, a method of operating an electronic system includes detecting an incoming transmission on a power line, and modifying a switching behavior of a switched-mode power supply coupled to the power line upon detecting the incoming transmission. Modifying reduces the level of interference produced by the switched-mode power supply.

Abstract: Multicast transmissions are efficient but do not allow for individual acknowledgement that the data was received by each receiver. This is not acceptable for isochronous systems that require specific levels of QoS for each device. A multimedia communications protocol is provided that uses a novel multi-destination burst transmission protocol in multimedia isochronous systems. The transmitter establishes a bi-directional burst mode for multicasting data to multiple devices and receiving Reverse Start of Frame (RSOF) delimiters from each multicast-destination receiver in response to multiple SOF delimiters, thus providing protocol-efficient multi-destination acknowledgements.
