Abstract: Systems and methods for tailoring the functionality of software applications are disclosed. Specifically, embodiments of the present invention may tailor the functionality of a software application by tailoring the features of the interfaces of the software application presented to a user based on one or more maturity levels of the user. In this manner, the set of features, and thus the functionality or complexity of a software application, may be tailored to the maturity levels of a user.

Abstract: A rotary valve system for a four stroke engine is provided. The rotary valve system includes: an engine having a plurality of cylinders, a crankshaft, a fuel injector and an exhaust manifold; an intake valve assembly rotatably mounted within the engine in communication between the fuel injector and the cylinders, the intake valve assembly forming a single transverse intake port adjacent each of the cylinders; and an exhaust valve assembly rotatably mounted within the engine in communication between the exhaust manifold and the cylinder, the exhaust valve assembly forming a single transverse exhaust port adjacent each of the cylinders, the exhaust valve assembly being located parallel to the intake valve assembly; the intake valve assembly and the exhaust valve assembly being operationally connected to the crankshaft.

Abstract: An exercise beverage vessel comprising a central, cylindrically shaped, hollow grip portion; a first, second, third and fourth cylindrical shaped, hollow disk member integrally formed with the grip portion to form a barbell shaped drinking vessel; a weight housing in connection with the third disk member having a weight chamber formed therein that is accessible through a fill aperture and having at least one transparent viewing portion of a size sufficient to allow a viewer to view a weight increasing agent level within the weight chamber; a plug member sized to frictionally fit within the fill aperture; and a hinged cap member, hingedly attached to the fourth disk member with a hinge mechanism, having a pivoting cover portion of a size sufficient to cover a drinking opening formed in the fourth disk member.
