Abstract: In some embodiments, a computer-implemented method of communicating on a shared medium is provided. A node computing device receives an incoming message via the shared medium and determines, based on the incoming message, whether the node computing device is the next computing device assigned to transmit on the shared medium. In response to determining that the node computing device is the next computing device assigned to transmit via the shared medium, the node computing device detects an end of the incoming message, and, in response, transmits an outgoing message via the shared medium. In some embodiments, a computer-implemented method of managing communication between node computing devices is provided. A maestro computing device transmits one or more configuration messages to establish a transmission order for the set of node computing devices to transmit messages on the shared medium, and transmits a start message that initiates the transmission order.

Abstract: An apparatus is provided comprising: a first power domain that includes a first component that operates at a first voltage level; a second power domain that includes a media access controller (MAC) that operates at a second voltage level; and a third power domain that includes a physical media access (PHY) device that operates at a third voltage level; wherein the first voltage level is higher than the second voltage level; and wherein the second voltage level is unreferenced; further including: a first reinforced electrical isolation circuit disposed on a first circuit path that includes at least one signal lane that extends between the first power domain and the second power domain; and a second reinforced electrical isolation circuit disposed on a second circuit path that includes at least one signal lane that extends between the MAC device and the PHY device.

Abstract: An Ethernet or other communications module can amplify and reinforce a signal received from a non-local source without requiring a transformer or other magnetic component. A semiconductor integrated difference amplifier circuit can be used to amplify and reinforce a differential mode component of the received signal, while also attenuating a common mode component of the received signal. A transmission compensation network can generate a phase-shifted version of a locally transmitted signal being placed on the same communication terminals as the received signal during full duplex communications, for cancellation of such locally transmitted signal at inputs of a local receiver circuit. This can enhance detection of the received signal generated by the non-local source.
