    摘要: A marginal oil extraction system having an upper extraction unit, an extraction container, and a lower valve assembly. The marginal oil extraction system uses at least some of these components to cheaply extract oil from a stripper oil well. In some cases the system is capable of separating the oil from the water in the well with a solid barrier and can cheaply remove the oil from above the solid barrier. The system is cheap to install, easy to maintain and provides efficient access to what would otherwise be an inaccessible asset.

    摘要: A passive optical network suitable for use as a telecommunications access network, having a head-end transmitting in a first optical frequency and one or more subscriber stations transmitting on a second common optical frequency. A carrier sense, multiple access protocol, with collision detection, is used, the collision detection being performed in the subscriber and head-end stations.
