摘要： The present invention provides a method to at least partially power an Ethernet device from a plurality of balanced network power signals received through a network connection. This involves attaching the network device to the network, wherein network signals are received and contain both power signals and/or data signals. These network signals may be passed through surge protection and power-conditioning circuitry wherein the output of these circuits may be provided to a power absorbing circuit. This power absorbing circuit may separate the communication signal and power signal from the network signal. The communication signal may be passed to a network physical layer while the power signal may be passed to a power distribution module. Additionally, because certain embodiments may provide multiple pairs of network power signals to the power absorbing circuit, the current or power associated with each power signal must be sensed and balanced. This may be done with an active control circuit. The balanced power signals may then be supplied from the power absorbing circuit to the network-attached device in order to at least partially power the network-attached device.
摘要翻译：本发明提供了一种从通过网络连接接收的多个平衡网络功率信号中至少部分地为以太网设备供电的方法。这涉及将网络设备连接到网络，其中网络信号被接收并且包含功率信号和/或数据信号。这些网络信号可以通过浪涌保护和功率调节电路，其中这些电路的输出可以被提供给功率吸收电路。该功率吸收电路可以将通信信号和功率信号与网络信号分离。通信信号可以被传递到网络物理层，而功率信号可以被传递到配电模块。另外，由于某些实施例可以向功率吸收电路提供多对网络功率信号，因此必须感测和平衡与每个功率信号相关联的电流或功率。这可以用主动控制电路完成。然后可以将平衡功率信号从功率吸收电路提供给网络连接的设备，以便至少部分地为网络连接的设备供电。

摘要： A signal isolator comprises an isolation barrier, a transmitter, a differentiator, and a recovery circuit. The transmitter is coupled to a first side of the isolation barrier and is configured to receive and convert an information signal to a differential signal that encodes information in the information signal in a single transition edge. The differentiator is coupled to a second side that is isolated from the first side of the isolation harrier and differentiates the differential signal. The recovery circuit is coupled to the differentiator and operates to recover an output information signal based on the information in the single transition edge.

摘要： An interface between two or more integrated circuit devices employs isolation techniques to provide electrical isolation of a digital signal for transmission of the digital signal between a master device and one or more slave devices. Unidirectional isolator channels are utilized to transmit bidirectional digital signals, and a selection of an isolator channel operating in an intended direction is performed by direction control logic. Logic that monitors read and write transactions operates to determine a desired direction of the digital signal and accordingly directs the digital signal through an appropriate isolator channel.
