Abstract: A cleaning robot may determine a three-dimensional model of a physical environment based on data collected from one or more sensors. The cleaning robot may then identify a surface within the physical environment to clean. Having identified that surface, the robot may autonomously navigate to a location proximate to the surface, position an ultraviolet light source in proximity to the surface, and activate the ultraviolet light source for a period of time.

Abstract: The Cellular Automata Music Generator (CAMG) is a software platform, application and engine that generates and modifies musical compositions in real-time using a system of networked modules that utilize the 1-dimensional cellular automata (CA) mathematical model. The music compositions are non-looping (i.e. the same few bars of music do not repeat over and over), can be any length, can have low memory and processing requirements compared to looping WAV or MP3 files, and follow psychoacoustic principles. The music generated is ever evolving and can be globally altered based on one-parameter change. The music engine can be utilized in computer games or to generate unique ringtones or any musical composition for cell phones or other mobile devices based on ten-digit inputs, such as telephone numbers. The ringtones or musical pieces can be generated automatically based on the telephone number of the in-coming telephone call, or manually by the user, who inputs a selected numerical sequence.
