Abstract: Techniques, systems and apparatus are described for implementing a telescopic contact lens. In one aspect, a telescopic contact lens includes an inner lens including optical apertures and aspheric reflectors, an outer lens of a biocompatible material, and a switching device that rapidly switches between normal and telescopic vision. The optical apertures of the inner lens includes a center aperture that allows light to pass through for normal vision and an annular aperture located on the periphery of the inner lens that allows light to enter for telescopic vision, The aspheric reflectors are configured between the annular aperture and the center aperture to reflect the light and magnify a visual image for telescopic vision.

Abstract: A LED bulb comprising a support having at least one LED mounted on a first side, the at least one LED being electrically coupled to a circuit mounted on a second side of the support for driving the LED bulb at a first or a second light intensity level, the circuit comprising input terminals connectable to a power supply for receiving an input voltage; a LED driver component for adjusting the input voltage supplied to the at least one LED; a comparator circuit for detecting the input voltage and if above a threshold voltage closing a switch to drive the LED bulb at the first light intensity level.

Abstract: A system and method of capturing solar energy, and related method of manufacturing, are disclosed. In at least one embodiment, the system includes a first lens array having a plurality of lenses, and a first waveguide component adjacent to the lens array, where the waveguide component receives light, and where the waveguide component includes an array of prism/mirrored facets arranged along at least one surface of the waveguide component. The system further includes at least one photovoltaic cell positioned so as to receive at least a portion of the light that is directed out of the waveguide. A least some of the light passing into the waveguide component is restricted from leaving the waveguide component upon being reflected by at least one of the prism/mirrored facets, hereby the at least some light restricted from leaving the waveguide component is directed by the waveguide toward the at least one photovoltaic cell.

Abstract: A variety of lenses, lens assemblies, imaging devices, applications for such lenses, assemblies and devices, and related methods of operation and manufacturing are disclosed. At least some embodiments of the invention relate to a lens that includes first and second inward-facing surfaces that are each at least partly reflective. The lens further includes a first aperture that is positioned around at least a portion of an outer periphery of one of the first and second inward-facing surfaces, and a second aperture existing proximate a central region of the lens. The light proceeding within the lens between the first and second inward-facing surfaces is reflected at least twice on at least one of the first and second inward-facing surfaces as it travels between the first aperture and the second aperture.

Abstract: This invention concerns architecture for a SIP stack that enables the addition or removal of new services without this having any impact on the other part of the stack. The user agent class contains sessions, the session class contain transactions and service implementations, while the transaction class simply contains service implementations. The user-agent class is programmed to retrieve session service implementations from the application and to attach them to session instances. The session class is programmed to receive transaction service implementations from the application, via the user agent class and to attach them to transaction instances. The proposed architecture allows an application to simultaneously support more than one version of a specific service. Added benefits also include making the customization process of these services quite easy.
