Abstract: A building management system is provided. The building management system includes one or more variable air volume units and a controller. The controller includes a processor and a memory. The memory stores processor executable instruction. The processor executable instruction when executed by the processor cause the building management system to perform functional tests on the one or more variable air volume units of the building management system to generate building data; analyze the building data to produce health information per functional test; and visualize a condition of the building system based on the health information.

Abstract: A forced air handling system includes an automated monitoring system. A method of operating the automated monitoring system includes initiating a calibration mode of operation via a controller. A plurality of dampers may then close via the controller. Once closed, a duct in communication with the plurality of dampers may be pressurized. A first air flow measuring exiting each one of the plurality of dampers may be obtained by a flow sensor. The duct is then depressurized and a second airflow measurement is taken, via the controller, exiting each one of the plurality of dampers. The controller calculates a statistical difference between the first and second airflow measurements.

Abstract: In one aspect, a method of generating a model for HVAC system control is provided. The method includes generating a model of the performance of an HVAC system, providing the generated model to at least one of an optimal control system and a diagnostic system, and automatically tuning the HVAC system using the generated model and at least one of the optimal control system and the diagnostic system.

Abstract: The risk of future fracture or deformity of vertebrae of a spine may be estimated by processing an image of at least one vertebra of a spine to compare data representing the appearance of the at least one vertebra with a statistical model of a corresponding part of a spine, the statistical model being formed from data representing images of spines for which information about the degree of fracture or deformity of each spine at a subsequent time is known, and deriving a measure of the similarity between the at least one vertebra of the spine and the model, which measure is representative of the likelihood that the spine will subsequently sustain a fracture or become deformed.
