Abstract: The invention relates to a device comprising a first optical Mach-Zehnder interferometric sensor (MZI1) with a large FSR, wherein a plasmonic waveguide (107) thin-film or hybrid slot, is incorporated as transducer element planar integrated on Si3N4 photonic waveguides and a second optical interferometric Mach-Zehnder (MZI2), both comprising thermo-optic phase shifters (104, 106) for optimally biasing said MZI sensor (MZI1) and MZI as variable optical attenuator VOA.

Abstract: A method for applying a patterned coating of resist onto a surface of a substrate, includes embossing flowable resist at least once, wherein the flowable resist is respectively embossed between a patterned surface of a stamp and a carrier, whereby the stamp surface is provided with a patterned resist surface. The stamp carrying a first patterned part of the resist coating and the carrier carrying a second part of the resist coating are separated from each other. The patterned resist coating is transferred, wherein the first patterned part of the resist coating on the surface of the stamp is pressed against the surface of the substrate and the patterned resist coating is transferred onto the surface of the substrate. The first patterned part of the resist coating is cured and a demolding step is performed by separating the stamp from the first patterned part of the resist coating.

Abstract: A magnetic position measuring device includes a sensor and a scale. At least one of the sensor and scale is movable in relation to the other. The sensor includes four sensor elements positioned along a longitudinal axis parallel to the direction of the movement. The scale is made of alternating and repeating first and second sections. The first sections have a first reluctance and the second sections have a second reluctance. The first sections each have a length "l" and the second sections each have a length "s". The Sensor includes a field plate and four sensor elements positioned on the field plate along the longitudinal axis. The four sensor elements include first and second outer sensor elements and first and second inner sensor elements.

Abstract: A berry stripping machine for grapes includes a machine housing, a berry stripping cylinder rotatably mounted therein, and a fill funnel for the grapes preceding the berry stripping cylinder. A spiked roller is coaxially mounted inside the berry stripping cylinder. The berry stripping cylinder and the spiked roller are driven by separate adjustable-rate drive units.
