Abstract:
The patent relates to a cuvette for analysis of liquid food products, which can be applied for analysis of various food fluids. This cuvette can be part of numerous kinds of apparatus for analysis of milk, vegetable oils or oils, extracted from biological products, or fluid food compositions, extracted as a result of proceeded secondary treatment. The cuvette is made of a body (3), which have an inlet pipe (1) on the one side and an outlet pipe (2) on the other side, where the three elements are mounted in a row for an one-way flow and are fixed together through a detachable screw connection (14), where in body (3) a measuring chamber (9) is formed by transparent plates (11) and through the inlet pipe (1) are mounted heat exchangers (10), made of a material with a high conductivity, where on these heat exchangers and in the body (3) are mounted temperature sensors (12) and heating elements (13).
Abstract:
In an example implementation, a substance detection method includes sensing for fluid in a chamber of a substance detection device. When fluid is sensed in the chamber, the method includes sensing again for fluid in the chamber. When no fluid is sensed in the chamber, the method includes initiating a substance detection process.
Abstract:
The present disclosure relates generally to a temperature dependent device. Embodiments of the invention provide information regarding the useful life of perishable goods.
Abstract:
Described is a jug comprising a filter for filtering milk, wherein the filter comprises one or more enzymes. In particular examples, the filter comprises lactase, the jug is for removing lactose from milk, and the jug includes an indicator for indicating to a user when the filter has reduced filtering ability.
Abstract:
The present invention relates to a milk deterioration detection system (1) and method (100) which detects deterioration or spoiling of milk non-invasively (without contact) via laser speckle contrast imaging. A milk sample (S) is held in a transparent container and deterioration of milk causes the roughness of a transparent surface of said container to change, said changes being monitored by laser speckle contrast imaging.
Abstract:
Procédé de calibration d'un appareil de spectroscopie infrarouge pour réaliser des spectres en vue de déterminer la concentration d'un composant C1 dans un fluide F1 d'un animal, qui comprend les étapes consistant à : a)- se munir d'échantillons dudit fluide F1 et d'un fluide F2 différent du fluide F1, provenant de chaque animal appartenant à un lot d'animaux représentatifs, le fluide F2 contenant des quantités décelables d'au moins un composant C2 qui a une relation directe ou indirecte avec une voie métabolique du composant C1, b)- mesurer la concentration du composant C1 dans les échantillons de fluide F1 à l'aide d'une méthode de référence, c)- réaliser le spectre d'absorption IR complet des échantillons de fluide F2, d)- identifier sur les spectres d'absorption des échantillons de fluide F2, les plages spectrales qui sont corrélées avec la concentration du composant C1 dans les échantillons de fluide F1, et e)- calculer en se fondant sur au moins une desdites plages spectrales corrélées, un modèle mathématique prédictif de la concentration du composant C1 dans le fluide F1. Le procédé s'applique à la prédiction des teneurs de composants d'un premier fluide à partir du dosage de composants dans un autre fluide. Il s'applique aussi à l'identification de composés impliqués dans une voie métabolique.
Abstract:
A nursing monitoring device includes an inlet conduit with an inlet opening to enable milk that is released from a nipple to enter the inlet conduit. An outlet conduit with an outlet opening enables milk from the outlet conduit to enter a mouth of a nursing child. A measurement unit connected to the inlet conduit and to the outlet conduit enables measurement of a property of the milk that flows from the inlet conduit to the outlet conduit via the measurement unit. The outlet conduit is sufficiently long to enable placement of the measurement unit laterally to the mouth.
Abstract:
The invention relations to a method of determining milk characteristics for individual animals within a cohort of milking animals, where the method is characterised by the steps of: a) recording individual identification of animals present at a milking shed for a milking event; b) recording the timing of the milking event for individual animals; c) measuring at least one milk characteristic of milk collected from the cohort of milking animals; d) correlating the identification of an individual animal with the timing of the milking event to develop a profile of one or more milk characteristics for the individual animal. A system for implementing the method is also claimed. The inventive method and system has particular application for determination of characteristics of milk from a selected animal from a group of animals, particularly, but not limited to, milk yield, based on measurement of an ensemble of milk production from a group of animals, such as a dairy herd or cohort of dairy cows.
Abstract:
The invention relates to a method and a system for quantitative or qualitative determination of a target component in a liquid sample. The method comprises i) providing a plurality of magnetic particle comprising one or more capture sites for the target component on their respective surfaces; ii) providing a plurality of fluorophores configured to bind to the capture sites of the magnetic particles; iii) bringing the liquid sample into contact with the fluorophores and the magnetic particles in a flow channel of a micro fluidic device comprising a transparent window; and iv) at least temporally immobilizing the magnetic particles adjacent to the transparent window using a magnet, emitting exciting electromagnetic beam towards the immobilized magnetic particles, reading signals emitted from fluorophores captured by the immobilized magnetic particles and performing a quantitative or qualitative determination of the target component based on the read signal. The invention also relates to a suitable micro fluidic device for use in the method/system and a kit for preparing a liquid sample.
