摘要： A system and method are disclosed for using gas detection techniques to determine if a room is vacant or occupied, and to activate, dim or deactivate lighting based on a detected occupancy status. The system and method may monitor a concentration of a first gas using a gas sensor such as a CO2 sensor. The space may also be monitored using second and third sensors, and a vacancy status of the space may be based on the concentration of the first gas and information from the second and third sensors. The second and third sensors can be passive infrared sensors, ultrasonic sensors, gas sensors, microwave sensors, audio sensors, or video sensors. An electrical load associated with the space may be controlled based on the determined occupancy/vacancy status. Other embodiments are described and claimed.

摘要： Document comparisons can be performed at a semantic level by utilizing a rules base in which groups of rules are applied sequentially. In one implementation, (1) syntactic rules are applied to a document to form a tagged sequence in which individual words are tagged with their syntactic categories, (2) ambiguity rules are applied to the tagged sequence to resolve ambiguities, thereby providing a resolved tag sequence, (3) grammar rules are applied to the resolved tagged sequence to determine semantic roles of individual tagged words, thereby providing a role-specific resolved tagged sequence, and (4) property rules are applied to match properties (e.g., adjectives) with the words they modify, thereby providing a semantic feature structure. The semantic feature structure is then compared to at least one other structure.
