Abstract: The invention relates to a user device comprising: an output component for outputting media content to a user; computer storage holding a user model of a user, the user model comprising personal information of the user; an input component configured to receive a content identification document identifying pieces of content to be output to the user by the output component: a content modifier configured to modify the document received by the input component based on the user model of the user, the content modifier operable to filter out at least one piece of content identified by the content document to generate a modified identification document, wherein the output component is configured to interpret each piece of content identified in the modified identification document for outputting to the user, wherein the filtered out piece(s) of content is not provided to the user.

Abstract: The invention relates to a method for implementing forwarding in playback of video content, in which the video content is associated with commercials, the method comprising: determining a set of commercials that are skipped in forwarding the video content; and applying a function to determine the playback of the set of commercials when the forwarded video content is played, wherein the function is programmable.

Abstract: An optical cavity is combined with non-linear optical crystals and a laser source to generate light radiation at a frequency about 1.5 times the frequency of the initial laser source while having a wavelength 2/3 that of the initial laser source. The optical cavity comprises mirrors of relatively high reflectivity for optical radiation at a frequency of F/2, superior transmission for radiation at a frequency of 3/2*F to extract the final radiation and mirrors with relatively immediate or high reflectivity, or generally high transmission for radiation at a frequency F. The effective optical length of the cavity is precisely tunable by operating at least one of the mirrors that form the cavity.

Abstract: An optical cavity is combined with non-linear optical crystals and a laser source to generate light radiation at a frequency about 1.5 times the frequency of the initial laser source having a wavelength ? that of the initial laser source. The optical cavity comprises mirrors with relatively high reflectivity for optical radiation at a frequency of F/2, superior transmission for radiation at a frequency of 3/2*F for extracting the final radiation and mirrors with relatively immediate or high reflectivity, or generally high transmission for radiation at frequency F. The effective optical length of the cavity is precisely tunable by acting on at least one of the mirrors that form the cavity. The optical cavity contains at least two non-linear optical crystals: at least one of which satisfies the phase-matching-quasi phase-matching-condition for non-linear conversion F 2*F/2, and at least one of which satisfies the phase-matching—or quasi phase-matching-condition for non-linear conversion F+F/2? 3/2*F.

Abstract: The invention relates to new and known compounds as well as methods for preventing the attachment of aquatic organisms to surfaces which are submerged for extensive periods of time in water. More particularly, this invention relates to the protection of submerged surfaces with new isonitrile, formamide, isocyanate and isothiocyanate anti-fouling agents.

Abstract: The invention relates to methods for preventing the attachment of aquatic organisms to surfaces that are submerged for extension periods of time in water. More particularly, this invention relates to the protection of submerged surfaces with alkylamine derivatives as antifouling agents. The invention is beneficiary for the environment in that it will permit the use of copper- and tin-free paints.
