  • Publication number: 20170230082
    Abstract: Systems and methods for delivering energy on a bus used for communication between devices are provided. Systems and methods dynamically provide a predetermined recovery time between communication messages calculated from forward and response message types and/or length, and a model of the energy reserve in the network devices to allow time for energy storage circuits in the devices to charge. In addition or alternatively, systems and methods provide an extra recovery time between messages to allow the bus voltage to recover from a fold-back mode and/or include an extra current limit circuit to increase a power supply current when the combined energy required by the network devices is greater than a current limit on a power supply.

  • Patent number: 9037918
    Abstract: Systems for helping identify faults on a bus, as well as to determine the topology of a bus network, are disclosed. A system according to one embodiment includes a bus interface for connecting to a bus and a switch coupled to the bus interface, the switch configured to alternate between an open state and a closed state. The system is connected to the bus via the bus interface when the switch is in the closed state, and the system is disconnected from the bus via the bus interface when the switch is in the open state.
