Abstract: A Power over Ethernet (PoE) system that includes a power source, an Ethernet transmission line, a powered device and a reset device is provided. The power source is configured to generate an electric power signal having a power level. The powered device is configured to receive the electric power signal through the Ethernet transmission line. The reset device includes a power terminal and a reset circuit. The power terminal is electrically coupled to the Ethernet transmission line. The reset circuit is electrically coupled between the power terminal and a ground terminal. Upon receiving a control signal, the reset circuit is configured to vary a voltage level of the electric power signal from the power level to a non-zero reset level for a predetermined time period to reset the powered device.

Abstract: Systems and methods for managing a wireless mesh network, in particular to provide for the simple configuration of a plurality of unconfigured devices to be added to the wireless mesh network are disclosed. New devices in the vicinity of a wireless mesh network broadcast signals, such as beacons, advertising their ability to join the wireless mesh network. These beacons may be detected by a primary device, such as a primary router, that is part of and can manage the wireless mesh network. The primary device is then able to establish temporary connections with the new devices that are eligible to join the wireless mesh network. The primary device may generate a list of potential new nodes for presentation to an electronic device, such as a smartphone, from which a user can select a plurality of new devices to add as new nodes. Alternatively, the primary device automatically adds devices as nodes to the wireless mesh network based on various criteria.

Abstract: A network device that includes a power source device (PSE) circuit, a MOS switch, a network connector and a detection unit is provided. The network connector has a first and a second terminal electrically coupled to the voltage source and to the ground terminal through the MOS switch respectively. Under the condition that the PSE circuit is not activated, the detection unit detects a first non-zero voltage pulse at the second terminal to determine that a powered device is attached to the network connector to activate the PSE circuit to generate and transfer the power to the powered device through the network connector. Under the condition that the PSE circuit is activated, the detection unit detects a second non-zero voltage pulse at the second terminal to determine that the powered device is detached from the network connector to deactivate the PSE circuit to stop generating the power.
