  • Patent number: 11244023
    Abstract: A method includes storing a plurality of content items and storing one or more associations. Each of the associations includes an association between exactly two of the content items. The method may also include causing a graphical user interface (GUI) to be presented on an electronic device. The GUI may include a first representation of a first content item, a list of representations comprising a second representation of a second content item and a third representation of a third content item, a first visual indicator indicating a first association between the first content item and the second content item, and a second visual indicator indicating a second association between the first content item and the third content item. The method may also include receiving a user input comprising an instruction to create an additional association between the first content item and the second content item.

  • Publication number: 20200151225
    Abstract: A method includes storing a plurality of content items and storing one or more associations. Each of the one or more associations includes an association between exactly two of the plurality of content items. The method may also include causing a graphical user interface to be presented on a display of an electronic device. The graphical user interface may include a first representation of a first content item of the plurality of content items, a list of representations comprising a second representation of a second content item of the plurality of content items and a third representation of a third content item of the plurality of content items, a first visual indicator indicating that a first association of the one or more associations exists between the first content item and the second content item, and a second visual indicator indicating that a second association of the one or more associations exists between the first content item and the third content item.

  • Publication number: 20050160734
    Abstract: Applicant's preferred embodiment utilizes municipal wastewater effluent to replenish a depleted geothermal field. Condensate produced by expanding steam produced in the geothermal field through a steam turbine-generator may be pooled with cooked water collected from said field, and then directed through a penstock from a higher elevation to a lower elevation where further energy is extracted through a traditional hydroelectric turbine-generator. The cooked water and condensate may be treated to produce potable water and/or distributed for public consumption either before or after being directed to the hydroelectric turbine-generator. The effluent is pumped up to the geothermal field during off-peak periods of electric consumption, and the hydroelectric generation is accomplished during periods of peak electric demand. A fraction of the effluent may be used as cooling water for the steam turbine-generator and its associated condenser before injection into the geothermal field.
