Abstract: A quadrilobe connector defined by a cross-sectional shape derived from a square, where each of the corners of the square is replaced with an arc of a circle, and ends of two adjacent arcs meet to form a depression between the arcs. Further, each of the four arcs is equal in radius and intersects tangentially to each other arc.

Abstract: A planetary gearbox, also known as an epicyclical gearbox is disclosed herein. The gearbox includes multiple rows of planets and a ring gear. The sun gear is a single unitary structure which simultaneously engages the multiple rows of planets. The system lowers the stress level on torque generating devices incorporating such a gearbox.

Abstract: A loading device for lifting an elongated object having an elongate axis includes a frame having a first fulcrum surface and a second fulcrum surface, a first effector arm that pivots about the first fulcrum surface, a second effector arm that pivots about the second fulcrum surface, and an actuator moving the first effector arm and the second effector arm between a retracted position and a deployed position.

Abstract: A portable rolling massager is provided that includes a spindle, a roller rotatably mounted on the spindle, and a covering for the roller that features a comfortable surface when applied to the skin and pressure is applied to muscles underlying the skin. Heating and cooling of the cover provides other therapeutic benefits. Storage in the spindle accommodates weights, flashlights, key storage, music devices, and the like. Hand grips having distal ends are designed to provide the ability to massage trigger points that develop in the muscles.

Abstract: A system for storing, managing, and accessing information on a network by providing an interface between a social network and a content network includes an applications platform. The system provides messaging and social networking facility incorporating enhanced instant messaging, file synchronization, network presence, interactive chat capabilities, text messaging, voice and video messaging, blogging, and email. The system includes a viewer, an indexing facility, and a storage facility. The viewer enables users to traverse content and provides services based upon context of time, place, structure, node, and observed user behavior. The viewer provides a means for users to interact with information on the network and services to manipulate information and transact activities. The indexing facility manages the structure of the network and tracks attributes and controlled vocabularies. The indexing facility supports navigation across the structure and resolves the logical index to a physical storage location.

Abstract: A method of preparing porous collagen matrices directly from connective tissues using an acidic solution substantially free of salt.
