Abstract: A method for automated computerized audio visual dubbing of a movie comprises (i) generating a three-dimensional head model of an actor in a movie, the head model being representative of specific facial features of the actor, and (ii) generating a three-dimensional head model of a dubber making target sounds for the actor, the dubber head model being representative of specific facial features of the dubber, as the target sounds are made. The method also comprises modifying at least a portion of the specific facial features of the actor head model according to the dubber head model such that the actor appears to be producing target sounds made by the dubber.

Abstract: A method using computer software for automatic audio visual dubbing (5) using an efficient computerized automatic method for audio visual dubbing of movies by computerized image copying of the characteristic features of the lip movements of the dubber onto the mouth area of the original speaker. The invention uses a method of vicinity-searching, three-dimensional head modeling of the original speaker (3), and texture mapping (10) technique to produce new images which correspond to the dubbed sound track: The invention thus overcomes the well known disadvantage of the correlation problems between lip movement in an original movie and the sound track of the dubbed movie.

Abstract: The present invention generally relates to safe and stable sunscreen compositions comprising of at least one sunscreen active ingredient in the form of an inert sol-gel microcapsules encapsulating ultraviolet absorbing compounds in any acceptable cosmetic vehicle. The composition according to the present invention can comprise several ultraviolet absorbers that may be encapsulated in the same sol-gel microcapsule or in different capsules. The hydophobicity/hydrophilicity character of the sol-gel microcapsules can be controlled by selecting suitable sol-gel precursors and suitable reaction conditions and can be chosen to be compatible with the cosmetic vehicle to be used in the sunscreen composition, thus, the present invention facilitates an easy incorporation of the composite sol-gel encapsulated sunscreen in all types of cosmetic vehicles including oil free compositions, with no necessary steps of heating or high shear forces.

Abstract: The present invention relates to a method for obtaining improved photostability of a sunscreen composition that contains at least two sunscreen active ingredients, which are photo-unstable when formulated together, by microencapsulating at least one of said active ingredients in an encapsulating material suitable for holding the encapsulated active ingredient material, thus reducing or preventing its leaching out of the capsules; and adding other acceptable components and additives needed for the preparation of said composition. The sunscreen active ingredients can be selected from UVA and UVB absorbers, preferably a combination thereof. In a preferred embodiment of the present invention said active ingredients are encapsulated in separate sol-gel microcapsules.

Abstract: A therapeutic, cosmetic or cosmeceutic composition for topical application, capable of stabilizing an active ingredient and delivering the active ingredient, comprising a plurality of microcapsules having a core-shell structure. The microcapsules have a diameter of approximately 0.1 to 100 micron. The core of each microcapsule includes at least one active ingredient and is encapsulated within a microcapsular shell. The shell is comprised of at least one inorganic polymer obtained by a sol-gel process, and the shell protects the active ingredient before topical application and is designed to release the active ingredient from the microcapsules following application. The composition is useful in encapsulating active ingredients, such as benzoyl peroxide, that are unstable in other formulation, or are irritating to the skin.

Abstract: The present invention relates to a novel process for preparing sol-gel microcapsules loaded with up to 95% (w/w) functional molecules or substances and to the products obtained by said process. Said process is conducted in two steps: (a) creating an oil-in-water emulsion by emulsification of a water insoluble solution comprising the sol-gel precursors and the molecules to be loaded, in an aqueous solution under appropriate shear forces; (b) mixing and stirring said emulsion with an aqueous solution at a suitably selected pH to obtain loaded sol-gel microcapsules in suspension. The microcapsules so obtained can further be subjected to cycles of isolation and rinsing. Incorporation of the final product, either in the form of a suspension or a powder, in cosmetic formulations affords a transparent cream when applying to skin and has a smooth and pleasant contact.

Abstract: The present invention generally relates to safe and stable sunscreen compositions comprising of at least one sunscreen active ingredient in the form of an inert sol-gel microcapsules encapsulating ultraviolet absorbing compounds in any acceptable cosmetic vehicle. The composition according to the present invention can comprise several ultraviolet absorbers that may be encapsulated in the same sol-gel microcapsule or in different capsules. The encapsulation of the ultraviolet absorbers reduces or even prevents the contact between the sunscreen compounds and the human tissue, thus reducing various adverse effects that are associated with the use of sunscreens, such as photoallergy and phototoxicity, and makes the composition safer for use. The encapsulation also reduces or even prevents cross reactivity between the sunscreen compounds and the packaging material and between the sunscreen compounds and any other component present in the composition, thus enhance the compositions stability.
