Abstract: Implementations of airflow capture hoods may include a central support coupled with a plurality of ribs configured to support a bottom end of a capture hood in an open position. The central support may be coupled with a plurality of poles configured to support an upper end of a capture hood in an open position.

Abstract: Implementations of an airflow capture hood flow control ring may include a flexible ring including a toroidal shape configured to couple around a base of an airflow capture hood. The ring may be configured to permit an airflow sensor coupled to the airflow capture hood coupled to an inlet to measure a flow of air into the inlet with at least 90% accuracy.

Abstract: Implementations of an airflow capture hood plate may include a plate including a plurality of openings therethrough. The plate may be configured to couple to a hood to guide airflow through the hood when the hood is placed over a diffuser of a heating, ventilation and air conditioning (HVAC) system and the plurality of openings in the plate may be configured to align with a plurality of ribs of a grid in the hood.

Abstract: An impact analysis software system is described which resides on a computer connected to a network in an enterprise. The system analyzes the impact of network events on the network, and includes a number of modules, including a number of data source adapters for interfacing with external data sources to thereby allow access by the system to enterprise-related data in the external data sources. The system further includes an impact analysis data structure populated with data accessed from the external data sources and defining relationships between the enterprise-related data. One or more action tree data structures comprise a routine which, when executed, acts upon the relationships defined by the impact analysis data structure to handle events. A message processor reads the network events and select one of the action tree data structures to handle each read network event.
