  • Ballast water treatment systems including related appratus and methods
    Publication number: 20110196814
    Abstract: Ballast water treatment apparatus and methods for preventing foreign aquatic invasive species form entering marine ecological zones by translocation in ship's ballast water. The apparatus includes a housing, a filter member, and UV water treatment chambers. Methods include use of a ship's fire hydrant system or ballast water discharge port for moving ballast water from the ship's ballast tanks into the apparatus for filtration and treatment. In-port service vessels and barges as well as dock-side service vehicles are equipped with the various treatment and filtration apparatus to provided in-port or dock-side ballast water treatment services. Related methods are also provided.

  • Transformer systems including standby loss prevention modules
    Patent number: 7808398
    Abstract: A transformer system for sensing load requirements and controlling a transformer accordingly to reduce power consumption when the load is in a stand by mode. One embodiment of the system includes a transformer implemented to receive an input and transform the input for use by a load, a sensor connected between an output of the transformer and the load, a communication link including the sensor and being connected between the transformer and the load, and a control switch connected to the transformer and sensor through the communication link. The sensor detects a mode of load operation and communicates a corresponding load mode signal over the communication link.
