Abstract: In one aspect of various exemplary embodiments, an exercise device comprising: an axial structure defining an axis of rotation; a user support structure rotatably coupled to the axial structure; and a ball member supported by the axial structure and disposed with radial symmetry corresponding points along the axis of rotation. Thus, the ball member may be substantially spherical in shape, elliptical, oblong, etc.

Abstract: A solar panel mount assembly includes a base portion mountable to an installation surface, and a support arm defining a support shoulder. The support arm is coupled to the base portion. The support arm and base portion cooperate to accommodate positioning the support arm at an adjustable distance relative to the installation surface. The solar panel mount assembly further includes a rotatable clamp assembly coupled to the support shoulder, and includes at least two brackets that releasably secure a portion of one or more solar panels.

Abstract: Solar panel connection assemblies for mounting solar energy panels to buildings as well as for affixing multiple solar energy panels together. Solar panel corner connection assemblies including a bracket that can be fastened to the corner edge of solar panel frames. Solar panel corner connection assemblies including flanges extending from the corner of a bracket for connecting with a neighboring flange on a neighboring bracket.

Abstract: Expandable fixation assemblies, expandable cranial fixation assemblies, and expandable intervertebral implant assemblies are provided for securing structures to bone and for securing bones and/or bone segments with respect to each other. An expansion member can be moved through at least a portion of an expandable fixation body, thereby causing expansion of the expandable fixation body, such that bone engagement features of the expandable fixation body engage surrounding structure, such as bone.

Abstract: A building rooftop mounting structure including a sacrificial material that allows freedom of movement between itself and the rooftop as well as between itself and the mounting structure.

Abstract: Rooftop solar energy module mounting systems that incorporate interchangeable mounting bases with a solar energy module frame.

Abstract: A semiconductor package includes a conductive base, a die disposed adjacent to an upper surface of the conductive base, a patterned conductive layer, and a dielectric layer encapsulating the die. The dielectric layer defines an opening through which the patterned conductive layer is electrically connected to the upper surface of the conductive base. The conductive base has a lateral surface including a first portion adjacent to the upper surface of the conductive base and a second portion adjacent to a lower surface of the conductive base, where the second portion is sloped inwardly with respect to the lower surface of the conductive base.

Abstract: Photovoltaic modules that are collapsible and angularly adjustable are made by mounting a photovoltaic panel in a frame, with a leg joined to the frame, the leg being manually adjustable to various angles, tilting the frame at various angles relative to the horizontal by simply lifting the frame. Certain embodiments also include interlocking features that join adjacent frames to form a rectangular array of modules.
