  • Patent number: 10168682
    Abstract: A system for providing location specific load-modifying demand response (DR) and methods for making and using same. The system advantageously can manage load on individual distribution level power circuits. Information regarding forecasted and real-time loading of individual distribution level power circuits is provided to a DR Locational Application. The DR Locational Application leverages the ability of smart devices containing real-time locational functionality, such as global positioning system, to either indicate to the consumer when it is appropriate to consume power, or automatically control the energy consumption, of the smart device along with any other loads that are verified by the smart device to be in the same location. The DR Locational Application can inform the consumer, the DR Aggregator or Crowd-Source Organization, and the distribution operator of the energy consumption sum of the response for each of its distribution level circuits.

  • Patent number: 4276752
    Abstract: A refrigerated cargo container, comprising no moving parts, for use in transporting temperature sensitive cargoes in aircraft. The container has six insulated walls with an insulated door along part of one of the walls, preferably the container's front wall, to provide for an air-tight container when the door is closed. An insulated bunker, having an insulated wall about a portion of its outer surface and a heat exchange portion along its bottom surface, containing a coolant such as solid carbon dioxide, is located within one of the top corners of the insulated cargo container. An air inlet duct extends along the top wall of the insulated container to one side of the insulated bunker to allow warm air from the interior of the container and the cargo to flow into the inlet duct along the top wall of the container and to pass along the side and bottom of the coolant bunker where the warm air is cooled by the heat exchange portion of the bunker.
