  • Patent number: 9588334
    Abstract: The invention relates to a Fabry-Perot interferometer and a method for producing the same. More specifically, the invention relates to Fabry-Perot interferometers which are controllable with one or several actuators, such as piezoelectric, electrostrictive or flexoelectric actuators. In prior art technology there is a problem to achieve a sufficiently small and uniform gap between mirrors. In the present invention an intermediate structure (85a, 85b, 95a, 95b, 81a, 81b, 91a, 91b, 98a, 98b) is used between a mirror and an actuator or between two mirrors. The method of production also includes measuring the width distribution of the gap in several phases, and providing pre-actuation of actuators.

  • Patent number: 9581499
    Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometeror a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometersis controlled into different modes during the measurement of a single target. The invention can be applied inoptical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.

  • Patent number: 9551659
    Abstract: An optical apparatus comprises an ultraviolet light source (100) configured to transmit the ultraviolet light to a sample (102), one or more wavelength dependent beam splitters (104) and at least two separate detectors (106, 108). Each beam splitter (104) receives, from the sample (102), a band of excitating ultraviolet light and at least one band of fluorescence associated with an interaction between the excitating ultraviolet light and the sample (102) in the optical path through the sample (102), directs the band of excitating ultraviolet light passed through the sample (102) towards a first detector (106), and directs the at least one band of the fluorescence towards at least one separate detector (108). The first detector (106) and the at least one separate detector (108) are simultaneously configured to form electrical signals carrying information on powers of the bands of the ultraviolet light and the fluorescence, respectively.

  • Patent number: 9518276
    Abstract: The invention refers to fungal cells, and especially to oleaginous fungal cells that have been genetically modified to produce enzymes of the pyruvate dehydrogenase bypass route to enhance their lipid production. Especially the cells are modified to over-express genes encoding pyruvate decarboxylase (PDC), acetaldehyde dehydrogenase (ALD) and/or acetyl-CoA synthetase (ACS), optionally together with a gene encoding diacylglycerol acyltransferase (DAT), or to express genes encoding PDC together with ALD and/or ACS. Methods of producing lipids, biofuels and lubricants using the modified fungi are also disclosed as well as expression cassettes useful therein. A new enzyme having phospholipid: diacylglycerol acyltransferase (PDAT) activity and a polynucleotide encoding it are also disclosed, which are useful in the lipid production.

  • Patent number: 9476975
    Abstract: Described herein is a passive wireless resonating non-linear sensor that is typically based on a ferroelectric varactor. The sensor replies its data at an intermodulation frequency when a reader device illuminates it at two closely-located frequencies. Furthermore, described herein is a general intermodulation read-out principle for passive wireless sensors. A sensor utilizes a mixing element, such as a varactor and it can be equipped with a capacitive, inductive, or resistive sensor element. When the sensor is illuminated with signals with two frequencies it replies the sensor data at an intermodulation frequency.
