Abstract: An aerial device (100) capable of controlled flight comprises a first body (110) comprising a lift generator for providing lift to the aerial device (100); a second body (208) comprising a substance dispenser (122) for controllably dispensing a curable substance for additive manufacture; an articulated coupling assembly (200) coupling the first body (110) to the second body (208); an actuator (212; 214; 216) operable to articulate the articulated coupling assembly (200) so as to move the second body (208), and thereby the substance dispenser (122), relative to the first body (110); and a controller operable to control the lift generator, the substance dispenser (122), and the actuator (212; 214; 216).

Abstract: A method and system are provided for hierarchical data warehousing in a context-variable data framework. The method includes building a context-variable data framework. The context-variable data framework comprises 1) a data point of interest 2) one or more contextual hierarchies based on a type for the data point of interest, and 3) an organizational hierarchy. The method further includes populating the context-variable data framework with information relating to the data point of interest. The method also includes storing the context-variable data framework and the information in a centrally accessible data store.
