An automatic and continuous method is presented to improve the accuracy of fiber optic distributed temperature measurements derived from Raman back scatterings utilizing two light sources with different wavelengths, by choosing the wavelengths of the two sources so the primary source's return anti-Stokes component overlaps with the incident wavelength of the secondary light source thereby canceling out the non-identical attenuations generated by the wavelength differences between Stokes and anti-Stokes bands.

The present invention is for an embossing stylus for embossing a design. The stylus has a central body portion, a removable embossing tip, having at least one embossing point and a spring biasing mechanism. The spring biasing mechanism is disposed on one end of the central body portion, and is configured to contact the removable embossing tip, biasing the embossing point in an outward direction away from the central body portion, such that the embossing point can be used to emboss the desired design.

A method and an apparatus for pulse-amplitude equalization of rational harmonic mode-locked optical pulses provides modulation voltages greater than a switching voltage of a dual-electorde Mach-Zehnder modulator to electrodes of the Mach-Zehnder modulator, so that rational harmonic mode-locked optical pulses experience the same transmission coefficient through the Mach-Zehnder modulator, to thereby achieve amplitude-equalized rational harmonic mode-locked optical pulse trains.

A method of forming an electrically conductive element in an integrated circuit is disclosed. The method includes depositing a composite polymer dielectric film onto a silicon-containing substrate, wherein the composite polymer dielectric film includes a silane-containing adhesion promoter layer formed on the silicon-containing substrate, and a low dielectric constant polymer layer formed on the adhesion promoter layer, depositing a silane-containing hard mask layer onto the composite polymer dielectric film, exposing the adhesion promoter layer and the hard mask layer to a free radical-generating energy source to chemically bond the adhesion promoter layer to the underlying silicon-containing substrate and to the low dielectric constant polymer layer, and to chemically bond the composite polymer dielectric film to the hard mask layer, etching an etched feature in the hard mask layer and the composite polymer dielectric film, and depositing an electrically conductive material in the etched feature.
