Abstract: Unique content generated by a group of individual users is evaluated. First unique content provided by a first user via a social networking website interface is collected at a tangible host server. Second unique content provided by a second user via the social networking website interface is collected at the tangible host server. User input ratings from individual users of the social networking website interface are collected so as to rate the first unique content and second unique content. In a first evaluation stage, the first unique content and second unique content are evaluated based on user input from individual users of the social networking website interface so as to comparatively rank the first unique content and second unique content.

Abstract: An RF coupler incorporating a pair of branch circuits which combine first and second input signals supplied at the same impedance level, amplitude and phase into an output signal at the same impedance level, twice the amplitude and phase shifted with respect to the input signals when both input signals are present, and which, if only one of the input signals is present, passes that input signal through its branch circuit to the output without loss, while terminating the branch circuit associated with the absent input signal with an equal impedance.
