Abstract: A System and method for the application of in-memory analysis of network data applied to spatial market segmentation with demand estimates and competitor information comprising multiple data extractors, a descriptive module, a predictive module, a learning module, at least one application programming interface, and a visualization tool are disclosed. An example of network data is machine readable data that is acquired through an application programming interface. An example of in-memory analysis is the use of in-memory processing and storage objects. A descriptive module is configured to produce market features. An unsupervised learning module is configured to produce market segments and a visualization tool is configured to evaluate one or more market scenarios and to display market features with maps and charts.

Abstract: A ring pen device convertible between a use as a finger ring and a writing implement includes: (a) a ring hull; (b) a hull insert that is insertable within the ring hull, the hull insert including a channel; and (c) an extendible pen assembly in the hull insert, the pen assembly including at least one marking tube; wherein the pen assembly has a retracted position within the hull insert, and an extended position in which a portion of the marking tube extends from an end of the channel in the hull insert. The pen assembly preferably includes a slide bar with at least one pair of matching stops extending from it, and at least one marking tube adjacent the slide bar, each slide bar stop being removably engageable with at least one of the notches.
