Patent number: 8249841Abstract: A computerized tool for assessing conditions in a room includes a data extraction module for at least one of modeling and extracting environmental condition data of a room and a layout module for calculating a layout of the room from the environmental condition data. The computerized tool may also include a temperature module for at least one of modeling and extracting temperature data in the room and a thermal profile module for calculating a thermal profile of the room from the temperature data. The thermal profile may be overlayed on the calculated layout to thus enable the relationship between the thermal profile and the room layout to be visualized.Type: GrantFiled: January 29, 2007Date of Patent: August 21, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ernesto J. Ferrer, Carlos E. Ramirez, Marcos A. Batista, Christian J. Bonilla, Cullen E. Bash
