  • Publication number: 20080063605
    Abstract: The invention relates to a method and a corresponding device for multipurposely supporting a randomly shaped and/or possibly complex with respect to a rigid base (11) part (1) by fixing a working reference, wherein the inventive method consist in interposing at least one deformable constant-volume chamber (3) which is sealed and filled with incompressible particles (4) between a maintainable part and the rigid base (11) and in lowing pressure inside the deformable constant-volume chamber (3) by means of a vacuum source (5) connectable thereto, thereby enabling the particles (4) to be amalgamated into a solid block which thrusts at least partly on the rigid base (11) and maintains the part (1) by fitting the shape thereof.

  • Publication number: 20050165462
    Abstract: The present invention provides devices, methods of manufacture, methods of use and kits related to transmitting and diffusing light for delivery to a target site. Techniques are provided which allow accurate control of the illumination profile with a diffuser tip design which is easily produceable, relatively inexpensive and provides countless variations to obtain desired illumination profiles. This is achieved with the use of at least one scattering region having a conical shape. The number of conical scattering regions, the dimensions of such region(s), and the scattering properties of the scattering materials may be selected individually and/or collectively to selectively control the resulting illumination profile. In addition, the conical features allow for other beneficial design features, such as a smaller cross-sectional diameter than is typically achievable with other techniques.
