Purchase and delivery of digital content using multiple devices and data networks

Abstract: A system that facilitates the purchase and delivery of audio and video content (e.g., entertainment media) over the Internet is disclosed. In a preferred embodiment, the disclosed system allows a user who hears or sees an audio or video broadcast to use a cell phone or other wireless device to order the broadcast material, and have it remotely delivered to an independent device (e.g., the user's personal computer) without further user intervention. Thus, the system allows the user to order the desired content using a wireless device that the user will often have in his or her possession when he or she hears or sees the desired content, but to have the content delivered to a second remote device.

Advanced tools for speech synchronized animation

Abstract: A random access animation user interface environment referred to as interFACE enabling a user to create and control animated lip-synchronized images or objects utilizing a personal computer for use in the users programs and products. A real-time random-access interface driver (RAVE) together with a descriptive authoring language (RAVEL) is used to provide synthesized actors ("synactors"). The synactors may represent real or imaginary persons or animated characters, objects or scenes. The synactors may be created and programmed to perform actions including speech which are not sequentially pre-stored records of previously enacted events. Furthermore, animation and sound synchronization may be produced automatically and in real-time. Sounds and visual images of a real or imaginary person or animated character associated with those sounds are input to a system and may be decomposed into constituent parts to produce fragmentary images and sounds. A set of characteristics is utilized to define a digital model of the motions and sounds of a particular synactor. The general purpose system is provided for random access and display of synactor images on a frame-by-frame basis, which is organized and synchronized with sound. Both synthetic speech and digitized recording may provide the speech for synactors.

SBEACH: Numerical Model for Simulating Storm-Induced Beach Change

Abstract: : This report provides guidance for implementing SBEACH, the Storm- Induced BEAch CHange model, via a user interface available for the personal computer. SBEACH simulates beach profile change, including the formation and movement of major morphologic features such as longshore bars, troughs, and berms, under varying storm waves and water levels. The personal computer version of SBEACH is accessed through a user interface which facilitates data entry and manipulation, graphical representation of input and output, and execution of the model. The interface also provides considerable error and range checking prior to actual running of the model. The first two chapters of the report present information about applying the model, including hardware requirements, loading SBEACH onto a hard disk, discussion of the interface structure through which the numerical model is operated, and guidance for model calibration. The final chapter is written as a tutorial, guiding the user in installing, running, and working through several example simulations.

Artificial neural-network based feeder reconfiguration for loss reduction in distribution systems

Abstract: Strategies are proposed to reconfigure the feeder in distribution systems by using artificial neural networks (ANNs) with mapping ability. ANNs determine the appropriate system topology that reduces the power loss according to the variation of load pattern. The control strategy can be easily obtained on the basis of the system topology which is provided by ANNs. ANNs are designed in two groups. The first group estimates the proper load level from the load data of each zone. The second determines the appropriate system topology from the input load level. Several programs with the training set builder are developed for the design, the training, and the accuracy test of artificial neural networks. The performance of neural networks designed is evaluated on the test distribution system. Neural networks are implemented in FORTRAN language and trained on a 386 PC. >
