Abstract: Various embodiments of the present invention provide a two-wire (e.g., unshielded twisted pair) bus system that is simple (e.g., no microcontroller required in slave devices), synchronous with embedded clock information, inexpensive, automotive EMC compliant, and has sufficient speed and bandwidth for a large number of slave devices/peripherals, and also provides various protocols that can be used in various communication systems such as a two-wire bus system. The two-wire bus optionally may be self-powered, i.e., the master device may provide power to the slave devices over the two-wire bus.

Abstract: Network nodes acquire bandwidth in contention-based networks for handling video traffic. A request to reserve a channel for transmission of a payload is sent prior to a network node receiving the payload. The payload is a burst of video data that is generated periodically. A network node determines a time period for reserving the channel. The network node determines when to initiate contending for the channel and the time period for transmitting the payload to another network node. A network node determines when a payload is expected to arrive and monitors its back off time period at least a time period prior to receiving a payload. The network node also monitors transmission of the payload and adjusts when to initiate contending for the channel.

Abstract: Power management techniques in distributed communication systems in which the power available at a remote unit (RU) is measured and compared to the power requirements of the RU. Voltage and current are measured for two dummy loads at the RU and these values are used to solve for the output voltage of the power supply and the resistance of the wires. From these values, a maximum power available may be calculated and compared to power requirements of the RU.

Abstract: A PoDL system includes a PSE supplying DC power and Ethernet data over a single twisted wire pair to a PD. Prior to coupling the DC voltage source to the wire pair, the PD needs to receive sufficient power to perform a detection and classification routine with the PSE to determine whether the PD is PoDL-compatible. The PSE has a low current, pull-up current source coupled to a first wire in the wire pair via a first inductor. This pull-up current charges a capacitor in the PD to a desired operating voltage, and the operating voltage is used to power a PD logic circuit. The PD logic circuit and a PSE logic circuit then control pull-down transistors to communicate detection and classification data via the first wire. After the handshaking phase, the PSE then applies the DC voltage source across the wire pair to power the PD for normal operation.

Abstract translation: PoDL系统包括通过单个双绞线对PD提供直流电源和以太网数据的PSE。 在将直流电压源耦合到线对之前，PD需要接收足够的电力以执行与PSE的检测和分类例程，以确定PD是否与PoDL兼容。 PSE具有通过第一电感器耦合到线对中的第一线的低电流，上拉电流源。 该上拉电流将PD中的电容器充电到期望的工作电压，并且使用工作电压为PD逻辑电路供电。 然后，PD逻辑电路和PSE逻辑电路控制下拉晶体管，以经由第一线路传送检测和分类数据。 在握手阶段之后，PSE将通过电线对施加直流电压源，为PD供电以进行正常工作。
