Abstract: A modeling system is provided which comprises a physical atomic modeling system structured for use in conjunction with a computer-implemented application which can execute a vision detection and analysis algorithm. When used to form molecular representations or models, the modeling system can be used to make molecular bonding visible, tangible, and more readily understandable to a student or other user. Various embodiments of the invention leverage the effectiveness of tangible, tactile systems to create a learning experience which increases understanding of atomic bonding at the valence electron interaction level.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a story development tool. In one aspect, a method includes presenting, for selection by a user, one or more settings and one or more characters. The method further includes receiving a selection by the user of a setting and a character for three or more acts of a story, wherein one of the three or more acts is a beginning act and another one of the three or more acts is an ending act. The method further includes receiving a data identifying a particular action. The method further includes receiving data indicating a transition between two of the three or more acts, wherein the transition is triggered by the particular action. The method further includes determining whether there exists a path from the beginning act to the ending act based on the data indicating the transition.

Abstract: A system and a method for the transmission and reception of digital data wirelessly using acoustic tones comprises a device having an encoder, a modulator system, a demodulator system, and a decoder. The modulator system uses a plurality of acoustical tones with a fundamental frequency and multiple harmonics that are amplitude modulated. The received signal is demodulated and detected by quadrature detectors comprising replicas of the acoustical tones. An extended Golay code based decoder is used for correcting errors occurring during transmission.
