Abstract: A controlled-power RJ45 socket includes a housing having a cavity to receive an RJ45 plug. The socket further includes electrical contacts positioned in the cavity and that come in contact with electrical contacts of the RJ45 plug when the RJ45 plug is plugged into the RJ45 socket. A switch is positioned to disconnect the power to the electrical contacts of the RJ45 socket before the electrical contacts of the RJ45 plug are physically detached from the electrical contacts of the RJ45 socket during a de-mating of the RJ45 plug from the RJ45 socket.

Abstract: A lighting system includes a gateway device having a user input interface. The lighting system further includes a first lighting device configured to wirelessly communicate with the gateway device, and a second lighting device configured to wirelessly communicate with the gateway device. The gateway device is configured to initiate wireless communications with the first lighting device and the second lighting device in response to an input provided to the gateway device via the user input interface.

Abstract: Devices associated with a lighting application can utilize multiple communication technologies for communicating with multiple devices that have different power consumption constraints and different transmission ranges. Communications and signaling can be managed to extend battery life. A battery-powered occupancy sensor can communicate occupancy information via a radio. The radio can be placed in sleep mode to preserve battery life. A communication node in the application can support intra-network and inter-network communications, for example with remote devices and systems.

Abstract: A multi-network gateway device includes a lighting network interface circuit configured to communicate with lighting devices using first wireless signals compliant with a first communications standard. The gateway device further includes a location-based network interface circuit configured to communicate with asset tags using second wireless signals compliant with a second communications standard that is different from the first communications standard. The gateway device also includes a processor configured to control the lighting network interface circuit to transmit a lighting control command based on identification information received wirelessly by the location-based network interface circuit.

Abstract: A wireless network system includes a primary wireless access point (AP) and a first access point node (APN) including a first lighting device with a first integrated wireless access point. The wireless network system further includes a second APN including a second lighting device with a second integrated wireless access point. The first APN and the second APN are wireless network clients to the primary AP and wirelessly communicate with the primary AP. The first APN is configured to wirelessly communicate with a first wireless network client. The second APN is configured to wirelessly communicate with a second wireless network client.
