Abstract: A power node provides energy management features in a networked data communications and control environment.

Abstract: A power node provides energy management and network expansion features in a networked data communications and control environment that may be utilized in an energy management system implementing a method of managing energy. Network expansion may be provided by integrating a networking bridge from a power line network to one or more wired network ports or a wireless network. The power outlet on the power node providing power to a device may be identified and associated with information about the device.

Abstract: Power is stored in a networked light allowing the networked light to send a message over the network providing information that the networked light is turning off if external power is no longer available.

Abstract: An apparatus and method for transferring energy between a rechargeable battery and a power distribution network. The minimum final energy level may be determined at least in part from the historical energy levels and usage of the rechargeable battery. The time of day of charging the battery may be determined at least in part from information provided by the energy provider.

Abstract: Various methods of manufacturing a lighting apparatus and embodiments of a modular networked lighting apparatus are disclosed. One method defines a mechanical form factor with a minimum set of electrical connections for a networking module, builds a subassembly of the networked lighting apparatus, the subassembly comprising attachment points compatible with the mechanical form factor for the networking module and contacts for the minimum set of electrical connections for the networking module, installs a networking module into the subassembly of the networked lighting apparatus, the networking module compatible with a selected networking protocol for the networked lighting apparatus, completes the final assembly of the networked lighting module, and marks the networked lighting apparatus to indicate the selected networking protocol for the networked lighting apparatus. In some embodiments, the lighting apparatus may function without the networking module installed.
