Abstract: The present invention is directed to enhanced expandable socket accessory systems that are enhanced with the ability to maintain retention of the socket accessory within the receiving slot to resist vertical inertial force, e.g., resulting from jostling, bumping or jumping. In particular, novel form factors, including necklaces, are capable of utilizing the enhanced expandable socket accessory systems of the present invention.

Abstract: A method may comprise: determining a total dissolved solids (TDS) concentration of a water source; correlating the TDS concentration to an ion concentration; and selecting at least one friction reducing polymer for a hydraulic fracturing operation based at least in part on the ion concentration.

Abstract: Systems, device configurations, and processes for a server to receive, from a user interface (UI) on a client, a request to generate a list from a selection of: an objective, vocabulary item, and/or grammar point mapped to a range of competency scores, and an audience. The server then selects data records storing data for the objective, vocabulary item or grammar point. The server then renders, for transmission and display on the client, a user interface control including a list of data for the objective, grammar point, and/or vocabulary item.

Abstract: A ducted shelf for an open-fronted display unit employing air curtains comprises a duct extending forwardly or rearwardly through the shelf and communicating at a forward end with a discharge or return opening, the duct being wider in the widthwise direction at the forward end than at a rearward end of the duct. Guide walls divide the duct into a group of channels disposed successively side-by-side in the widthwise direction. Each channel has a respective length reflecting a degree of widthwise offset between the rearward end and the forward end of that channel. A longer channel of the group has a greater width in the widthwise direction at its rearward and forward ends than a shorter channel of the group.

Abstract: A new and distinct Hibiscus cultivar named ‘RWOODS6’ is disclosed, characterized by large, semi-double white flowers with red-purple streaking and basal blotch. Flowers are up to 13 cm in diameter. Flower petals are strong and tolerate wind and rain well. The new variety is a Hibiscus, normally produced as an outdoor garden or container plant.

Abstract: A wireless client device having a touchscreen may run a class assessment tool. The tool may have an interface that displays a row of student pictures and names and enables a teacher to assess the students on various key aspects. The tool may display a rubric for each key aspect when the key aspect is hovered over or selected. The interface may include a matrix of assessment blocks having a plurality of individually selectable areas that enable a teacher to enter a key aspect score for each key aspect for each student. The interface may include a row of comment areas configured to receive a private message for a student and a row of final scores based on the key aspect scores of the student. A row of results may be displayed, where each result reflects whether a student passed or failed the class based on the student's final score.

Abstract: A ducted shelf for an open-fronted display unit employing air curtains. The shelf has a supply duct at a lower level communicating with a downwardly-facing forward discharge outlet and a return duct at an upper level communicating with an upwardly-facing forward return inlet. In front-to-back section through the shelf, a forward supply duct extension in front of the supply duct narrows forwardly above the discharge outlet and a forward return duct extension in front of the return duct reaches downwardly to the lower level of the shelf to lie forwardly of the supply duct. This beneficially reduces the thickness of the front of the shelf.
