Abstract: A penis lengthening device comprises a traction chamber with tapered sidewalls configured to secure the penis within the chamber by forming a partial vacuum therein. A flexible air seal covers the upper portion of the traction chamber and extends over the penis. As the chamber is evacuated, the air seal tightens around the penis, creating an air seal to retain the vacuum within the chamber. Tensile force is transmitted through the chamber to the penis of the user. Alternative “light traction” embodiments utilize a condom-like device configured to attach to an elastic band, or to suspend weights therefrom. Larger tensile forces are applied for shorter periods of a few minutes up to an hour using the traction chamber embodiment, and smaller forces of 1-2 pounds are applied for longer periods of several hours using a light-traction embodiment. Alternate between the two methods throughout the day enhances its effectiveness.

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.
