Abstract: A more efficient design for a solar cell based upon an optical waveguide along with cost effective methods for manufacturing the new solar cell. The optical waveguide based solar cell achieves an increase in efficiency through the use of a three dimensional geometry. In general terms, an inwards facing solar cell is wrapped around the length of an optical waveguide which then uses the end of the waveguide to capture the light and feed it in towards the lengthy solar cell.

Abstract: A method for controlling the sharing of Audio-only content, Audio-Visual content, and Visual-only content between Subscribers on a Telephone call after it is in a talking state. The Content Sharing service could be offered to telephony subscribers where it becomes another vertical telephony feature like Ring-Back Tone service. The Subscriber to this Content Sharing service will be given the ability to access and select content that will be played while on an active telephone call. All the subscribers connected on the telephone call will be given the ability to control the playing of the content. The content itself will be managed by a centralized Content Server allowing control by the Content Providers of the content provided to subscribers. The content being shared can be stored centrally on a server or be content stored directly by the user on their terminal devices.
