Abstract: A graphical user interface includes a plurality of single-action-selectable primary navigation buttons arranged around at least a portion of a periphery of a display content window. Selection of a single-action-selectable primary navigation button of the plurality of single-action-selectable primary navigation buttons causes corresponding content to appear in the display content window. Selection of at least one of the plurality of single-action-selectable primary navigation buttons causes content available in the display content window via subsequent selection of the at least one of the plurality of single-action-selectable primary navigation buttons to change. The graphical user interface also includes at least one secondary navigation button. The at least one secondary navigation button includes at least one of a back button, a next button, and a content-window scalar button. The graphical user interface also includes at least one dynamic program button.

Abstract: An optical memory 200 including an optical storage element 301 for storing data as a packet of photons, optical storage element 301 delaying in time the packet of photons traveling through the storage element from a first point to a second point. A photon source 302 receives an electrical signal representing data and injects the packet on to optical storage element 301 in response, and a detector 303 selectively detects the packet traveling on optical storage element 301. A feedback path 306/305 couples photon source 302 and detector 303 for recirculating the packet through storage element 301.
