Inverted U theory. The Inverted U theory was developed in 1908 by Yerkes and Dodson and it is a theory of arousal that considers that optimal performance occurs when the performer reaches an optimal level of arousal. The Inverted U theory seems to fit more accurately with observations of performance than the Drive theory.

Systems and methods for supporting or occluding a physiological opening or cavity

ActiveUS20100094335A1Promote re-endothelializationPromote tissue growthStentsDilatorsImplanted deviceEngineering
Implantable devices for placement at a cavity or opening such as an aneurysm are disclosed. The implantable devices, in a deployed condition, have a generally inverted U-shaped profile with a curved or angled framework support structure sized and configured for placement in proximity to tissue surrounding the opening and anchoring legs extending proximally from the framework structure sized and configured to contact the wall of a neighboring lumen at opposed locations. Occlusive and semi-occlusive membranes may be associated with the framework support structure and deployed over the opening to provide exclusion of the opening and flow diversion. Proximal anchoring segments providing additional lumen wall surface area contact for the implantable device following deployment may be incorporated.

Closure with tear strip

A closure for covering an opening of a container. The closure includes an inverted U-shaped peripheral channel for receiving the rim of a container therein. A tear strip is formed with the skirt of the closure via a tear line that circumscribes the skirt. A breakaway pull tab having an inner surface with U-shaped ribs, the combination of the surface and ribs being such as to provide a concavity which assists in gripping the tab to pull the strip away. Linear vertical ribs may be provided on the outer surface to provide further assistance in the gripping function. The skirt includes a recessed area underlying the pull tab for providing access to the pull tab.
