Abstract: Systems and methods are disclosed for acquiring various data from multiple sources that correct, format, package, and distribute data to end users. A data warehouse entity retrieves data acquired through a download interface in a format specified by the vendor, converts data into a standard or predefined data format, packages the standard format data, and distributes data to end users through a distribution interface. An incremental approach for updating data facilitates corrections to provide accurate reliable data. The data warehouse is populated with data from various vendors via a database containing data by downloading data file(s) from the individual vendor sources, parsing the data file(s) to a standard format, deleting duplicate data, and updating data if corrections or new data are identified.

Abstract: The present invention provides a control apparatus (11) for controlling luminescence produced by a light source (12) which includes a sensor (17) for sensing motion of air and a circuit (3) for varying the luminescence provided by the light source when motion of air is sensed. The sensor (17) is an air pressure sensor and all changes in the luminescence provided by the light source (12) are occasioned by sensed changes in air pressure. The present invention also provides lighting apparatus (10, 11, 12) which includes the control apparatus (11).
