Abstract: A device, system and method for determining user compatibility. Information may be received recording the usage of media by two or more users at associated user devices. The recorded media usage for the users may be compared. A measure of compatibility may be determined between the two or more users based on the comparison.

Abstract: A wheel hub for capturing energy created by road bumps and converting that into energy to be used in moving a vehicle in it's current direction of motion. Energy return is accomplished by elastic spring means, although the physical principle of operation is not directly obvious. Any road shock imparted upon the wheel will result in a radial displacement of an outer wheel hub and thus a radial force toward the center of the wheel. The radial force will be released as an axial rotation imparted upon a wheel hub assembly, thus increasing the axial speed in the current direction of motion. The principle is similar to that causing the earth to rotate around the sun. The wheel hub assembly will not wobble erratically since there is a dampening component by virtue of a vehicles weight and moment of inertia of a rotating wheel. Additionally, total shock absorbtion, is increased.

Abstract: We present a method for informed optimization of sampling vectors in multi-directional diffusion-weighted magnetic resonance imaging. The advantage of this optimization is that it is informed rather than being a naïve optimization of sampling vectors. Typically, sampling vectors are set relatively uniformly along a spherical surface. In this case, a scan at high imaging resolutions utilizes sampling vectors that are chosen based on the knowledge of the overall orientation distribution for the entire sample or region of interest. This overall orientation distribution is obtained by performing multi-directional diffusion-weighted scans at high angular resolution, but low or minimal voxel resolution. A subset of the vectors used in this high-angular-resolution scan is chosen to minimize the error in the final results. This optimal subset is not necessarily uniform in space.
