Abstract: An optical fiber for use in a Coherent Anti-Stokes Raman Scattering (CARS) endoscope, comprising a core guiding lightwaves at a pump wavelength and at a Stokes wavelength, the core being single-mode at both wavelengths. The core is surrounded by cladding layers, including an inner cladding layer, a trench cladding layer, an intermediate cladding layer and an outer cladding layer. The refractive index of the trench cladding layer is lower than those of both neighboring cladding layers so as to define a trench in the radial refractive-index profile. The bending losses of the fundamental LP01 mode of the fiber at the Stokes wavelength are limited while maintaining high confinement losses for the higher-order LP11 mode of the fiber at the pump wavelength. The combination of the intermediate and outer cladding layers forms a multimode waveguide for guiding a collected CARS signal generated by an object or medium probed with the endoscope.

Abstract: An electrical male terminal formed from a metal plate comprising a mating portion having contact surfaces adapted to electrically contact a female terminal. The mating portion comprises a first and second seamless strip electrically contacting the first and second female contact surfaces. The male terminal has a seam comprising a mating portion seam, within the mating portion, which is parallel to the longitudinal axis, and located on one of the side portions which are perpendicular to the contact surfaces of the mating portion.

Abstract: A light emitting device generates a broadband light beam in response to an excitation light beam. The light emitting device includes a matrix in which is provided a plurality of fluorescent components of different types. Each type of fluorescent component has an absorption spectrum and an emission spectrum respectively differing from absorption and emission spectra of other types of fluorescent components. The matrix and the types, concentration and positioning of the fluorescent components are selected to output the broadband light beam in response to the excitation light beam. The types of fluorescent components may include fluorescent compounds, quantum dots or a combination thereof. The light-emitting device above may be used as a fluorescent standard, or incorporated into a light source. Scattering elements may also be incorporated in the matrix.

Abstract: This terminal includes a folded contact section which has a longitudinal junction line and defines contact surfaces, a securing section, suitable to be accommodated in a terminal accommodating chamber of an insulating housing, and an intermediate section extending between said contact section and securing section. The intermediate section is deformed in torsion around the longitudinal axis (X), whereby the junction line is angularly offset from the contact surfaces around the longitudinal axis (X). The invention also relates to a process for manufacturing such a terminal, and to an electrical connector including such a terminal.

Abstract: An optical sensor for determining a distance between a target and a probe head is described. The optical sensor comprises a light source delivering a broadband spectrum; a fiber-optic Michelson interferometer (FOMI) for creating an interferogram; and an analyzer unit for receiving the interferogram from an output of the FOMI and for determining the distance of the target by finding a position corresponding to a maximum in a Fourier transform of the spectral distribution of the interferogram. The FOMI comprises a probing optical fiber terminated by the probe head and a reference optical fiber, the reference optical fiber having a fixed optical path length.

Abstract: The present invention relates to dry particulate encapsulation compositions comprising a water-insoluble matrix comprising at least 70% by weight of proteins, based on the total weight of the matrix and a moisture content of about 5 to 10% by weight, based on the total weight of the matrix and an encapsulate encapsulated in the matrix, wherein the matrix once wetted in a clear colorless aqueous solution or in mineral oil has a lightness value (L*) greater than about 40, a color vividness or Chroma (C*) lower than about 33 and a hue angle between about 70 and 90. The encapsulation compositions of the present invention are useful in encapsulating dyes, medications and vitamins. Fine particulate encapsulation compositions comprising natural dyes can be used in lieu of artificial lakes in confectionery, cosmetics and caplets color coatings.
