  • Patent number: 11095464
    Abstract: The present invention relates to a Power over Ethernet system (100) which supports additional optical communication via optical fibres. The powered devices (d1, d2, d3) may comprise circuitry to process optical signals, in particular triggering activation of the powered device (d1, d2, d3) after being in a low power state. The power supplying devices (s1-s6) may relay optical signals via direct optical paths. Optical paths in the network may improve timing accuracy of applications. The overall power consumption of the system may be improved in particular during low activity situations in which the system is primarily used for data communication. The additional optical communication paths may provide redundant paths and thus may increase the network's robustness.

  • Patent number: 11073859
    Abstract: The invention relates an electrical device for providing an output depending on an electrical input. The electrical device (1) is adapted to provide a constant output, if the electrical input is in a first electrical input range, and a dependent output, if the electrical input is in a second electrical input range, wherein the dependent output depends on the electrical input. The output can therefore remain constant, even if the electrical input, which is preferentially a DC grid voltage, fluctuates within the first electrical input range. Moreover, in the second electrical input range the output can be controlled by just controlling the electrical input like the DC grid voltage, without necessarily requiring an additional control construction of the electrical device. A resistance against fluctuations of the electrical input and a controllability of the output can therefore be realized in a relatively simple way.

  • Patent number: 10965476
    Abstract: The present invention relates to Power-over-Ethernet (PoE) systems. The invention proposes to use a classification event to communicate from the PD (121) to the PSE (110, 910). A sensor (310, 410, 510a, 510b) may determine a sensor value, shut down the PoE connection, and reconnect so that the power up cycle with the PSE (110, 910) will start. The sensor (310, 410, 510a, 510b) provides a PoE resistance related to a class 0, 3 where the class relates to the sensor value (e.g., class 0=presence detected; class 1=no presence detected). This procedure may be repeated (e.g. continuously, every minute or whenever the sensor value changes such that the PSE (110, 910) needs to be informed) and if needed multiple cycles can be used to increase the length of the message communicated.
