Abstract: A networked driver for a powered device (PD) includes an input connection capable of receiving power and data from an external power and data source, one or more output connections capable of supplying power and data to the PD, and a circuit capable of initiating delivery of a predetermined amount of power to the external load when a physical negotiated link between the external power and data source is lost.

Abstract: A system for control of conditioned air within a space includes a distribution hub connected to provide conditioned air, fresh air, or a combination thereof to the space, and to exhaust and/or return air from the space through the distribution hub, and a controller coupled to the distribution hub to control the provision of the conditioned air and the fresh air, and to control removal of the return air.

Abstract: A luminaire for lighting and for distribution of conditioned air within a space includes a housing having a lighting element, a duct opening, and at least one air vent coupled to the duct opening. The at least one air vent is configured to deliver conditioned air to the space. A method of controlling light and conditioned air delivery within a space, by a single combined lighting and conditioned air fixture, includes providing control and power signals to a controller coupled to the single combined lighting and conditioned air fixture, controlling lighting functions via the controller, and controlling conditioned air functions via the controller.
