Abstract: A method of making a three-dimensional structure including substructures is provided. The method includes directing laser light from a microscope objective through a photopolymerizable material to form a plurality of substructures each having at least one vertical wall directly attached to a vertical wall of an adjacent substructure. The substructures are individually formed in a sequence such that any second substructure that is formed in a location vertically disposed between the microscope objective and a first substructure has a wall that extends horizontally a shorter distance than a wall of the first substructure if a third substructure will subsequently be formed directly attached to the wall of the first substructure. The method is useful for minimizing passing laser light through a portion of an already formed substructure during formation of the three-dimensional structure.

Abstract: A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

The back optical reflector (10) may reflect (80b) at least 70% of light for each wavelength in the first wavelength range, and may transmit (90c) at least 70% of light (90b) for each wavelength in the second wavelength range.
