Abstract:
The invention relates to novel polymer-based microstructures, with outstanding shape accuracy and cost-effective processing. The novel polymers are based on hyperbranched macromolecules and enable remarkable property combination such as reduced shrinkage and associated low stress, high shape fidelity and high aspect ratio in patterned microstructures, with additional benefit of fast and low-cost production methods. The invention also relates to methods to produce these microstructures. The polymer-based microstructures are relevant for, but not limited to micro- and nano- technologies applications, including lab-on-a-chip devices, opto-electronic and micro- electromechanical devices, optical detection methods, in fields of use as diverse as automotive, aerospace, information technologies, medical and biotechnologies, and energy systems.
Abstract:
The present invention proposes a method and a computing system for deducing ink thickness variations from spectral reflectance measurements performed on a printing press or on a printer. The computed ink thickness variations enable controlling the ink deposition and therefore the color accuracy, both in the case of high-speed printing presses and of network printers. Ink thickness variations (305) are expressed as ink thickness variation factors incorporated into a spectral prediction model (203). The method for computing ink thickness variations comprises both calibration (204) and ink thickness variation computation steps. The calibration steps (204) comprise the calculation of ink transmittances from measured reflectances and the computation of possibly wavelength-dependent ink thicknesses of solid superposed inks. Wavelength-dependent ink thicknesses account for the scattering behavior of non- transparent inks or of inks partly entering into the paper bulk. The ink thickness variation factors are fitted by minimizing a distance metric between the reflection spectrum (407) predicted according to the thickness variation enhanced spectral prediction model (404) and the measured reflection spectrum (302). The ink thickness variation enhanced spectral prediction model (404) can be applied both in the visible wavelength range and in the near-infrared wavelength range. This enables computing unambiguously the thickness variations (305) of the cyan, magenta, yellow and black inks. Furthermore, a spectral reflection may be measured over a stripe of a printed page and used to predict the ink thickness variations (305) occurring within that stripe (402). This enables the real-time control of the ink deposition process on a printing press.

Abstract:
An optical modulator is arranged to compensate for the thermo-optical modulating effects induced by charge-injection based phase modulators. It comprises first modulator means (3), that receive optical radiation (11, 21), direct it along an optical path, apply a first predetermined optical phase modulation by the injection of free charges into the optical path, and output optical radiation (13, 22) so modulated. Compensator means (4) apply, to optical radiation output from (13, 22), or to be received by, the first modulator means (3), a second predetermined optical modulation chosen to substantially compensate for stray thermo-optical phase modulations imposed upon received optical radiation by the first modulator means (3) as a result of thermal dissipation within the first modulator means.
Abstract:
The method for producing inductive-type components, especially components of inductance coils, transformers or antennae, consists in micro-machining a plurality of first parts(1) that are joined to each other by connecting elements (2) or a connecting support on a first substrate that is made of a magnetic material; a printed multilayer plate (4,5) is inserted onto the arms (8a, 8b, 8c) of these first parts (1), whereby said plate has openings for the arms and metal windings that are terminated by at least two contact pads (7a, 7b); a second substrate made from a magnetic material is placed on top of and secured to the first substrate and the plate, whereby the second substrate is micro-machined prior thereto in order to obtain second parts (13) that are complementary to the first parts. The second parts are connected to each other by means of connecting elements or a connecting support. The components are then sorted and the contact pads on the lips (16,18) of the plate are folded against the base (9) of the core or the magnetic surface according to a special method of implementation in order to create a surface mounted device (SMD).
