Abstract: A connecting system for connecting a tensioning member to a free-space shaft may comprise an inner element having an element spherical outer surface truncated at opposite truncated ends and may include an element bore extending through the inner element and coaxial with the element spherical outer surface. The element bore may have a bore axis and a bore cross section sized and configured complementary to a shaft cross section of the free-space shaft. A retaining collar may include a collar spherical inner surface complementary to and configured to receive the element spherical outer surface, and may have opposing collar ends. The collar spherical inner surface may define a collar axis. The retaining collar may allow universal motion of the bore axis relative to the collar axis. The retaining collar may include an arching portion for connecting the tensioning member to the shaft.

Abstract: The present inventor devised, among other things, one or more exemplary systems, kits, methods, devices, assemblies, components, and/or software and related graphical interfaces related to signs with interchangeable illumination elements. One exemplary embodiment includes an illuminated sign assembly of two or more alphanumeric lighting elements formed of a transparent or translucent injection- or blow-molded plastic and including a number of surface-mounted light-emitting diodes (LEDs). Each of the alphanumeric elements plugs into power track, and can be independently rotated to a desired orientation relative the power track. In some embodiments, the each of the elements can be wireless controlled or programmed via a smartphone to blink or change colors according to a desired pattern or in response to ambient conditions. In still other embodiments, the lighting elements vertically stack onto a recharge station, and in yet others the elements are powered or recharged via resonant inductive coupling.
