Abstract: Parents and entities incentivize students to learn using pledges of cash, goods, and services. Students earn incentivized rewards by interacting with lessons on a digital computing device, such as a desktop computer, notebook, tablet, or “smart phone.” The lessons may include digital flash cards, text, pictures, figures, audio and video recordings ranging from classroom lectures, to classical music, to animation of scientific principles. In flashcard embodiments, the accuracy of each answer is recorded on a histogram corresponding to a particular flashcard, or the principles taught therein. The application generates performance metrics from histogram data. The performance metrics are used to generate control parameters that control the frequency and order flashcard presentation. Statistical analysis, adaptive learning and/or artificial intelligence programs refine the control parameters governing flashcard review, thereby optimizing the functionality.

Abstract: A video network includes public kiosks having digital storage capacity. Centralized inventory control manages the video files stored at individual kiosks or network LANs. A user requests a multimedia file for download, and selects various ancillary files and control features, such as languages, subtitles, control of nudity, etc. The requested file is encrypted according to an encryption key, watermarked, and downloaded from a high-speed port of a public kiosk to a hand-held proprietary high speed memory device of a user. Payment is received at the time of request or at the time of download, and royalties are distributed by the video network to copyright holders. Computer applications or playback devices allow users to store and/or play video files that have been downloaded to a hand-held device while managing and enforcing digital rights of content providers through the watermarking and/or encryption.

Abstract: An emergency vehicle transmits a Vehicle Present Signal when in transit on public roads responding to an emergency. The signal can include information relating to the type of emergency vehicle, local highway and terrain data, and the location, speed and direction of travel of the emergency vehicle. When the Vehicle Present Signal is detected by a first vehicle, a functional circuit within the first vehicle calculates the distance between the emergency vehicle and the first vehicle. If the vehicles are within a predetermined distance, a warning signal activates one or more warning systems, thereby notifying the driver of the first vehicle that an emergency vehicle is in the vicinity. A dead-band defined by first and second predetermined distances can be incorporated to prevent rapid cycling of the warning signal.
