Accordingly, disclosed are various connectors for connecting a colorimetric sensor array to a sample bottle. These connectors allow the colorimetric sensor array to be attached to a sample bottle after autoclaving, and introduce the headspace gas to the colorimetric sensor array at the appropriate time. Examples of these connectors include (1) a needle based connector that punctures the septum of standard bottle to allow gas flow in a chamber with a colorimetric sensor array, (2) a valve based connector that attaches to a sample bottle and when the valve is opened the headspace gas has a path to diffuse to contact a sensor array, and (3) a connector that includes a breakable seal that when broken puts the headspace gas in contact with the colorimetric sensor array.

A kit for diagnosing a disease includes a micro device including a flow path through which a sample to be diagnosed flows, and one or more grooves at a bottom portion of the flow path, and an aperture having an opening corresponding with the flow path.

A fast measurement method for micro-nano deep groove structure based on white light interference, including: establishing a white light interference system, using the white light interference system to measure the structure of the groove, the CCD camera collects and obtains multiple groups of groove interferograms and the serial number corresponding to each groove interferogram in each group; processing each group of groove interferograms of the groove sample to obtain the maximum contrast of each group of groove interferograms and the 3D reconstruction diagram of the local structure; extracting the interface reconstruction diagram in the 3D reconstruction diagram of the local structure according to each group of the groove interferograms; after splicing the interface reconstruction diagrams corresponding to all groups of groove interferograms, obtaining a 3D structural reconstruction diagram of the groove sample, and measuring the depth and width of the groove sample according to the 3D structural reconstruction diagram.

A device for characterizing substances in a scene, the device including a housing having a cavity configured to contain the substances, an opening for receiving the substances, an imager for capturing an image of the substances, an illumination source for illuminating the substances, a sensor for obtaining sensory data of the substances, a gas supply device for storing and inserting gas into the housing, a mechanical arm for inserting or removing the substances into or from the device via the opening, a syringe to add a material into the housing, a pump for creating a vacuum in the device, an air pump to suck air from the housing and removing the substances from the housing, a fan for cooling the housing, a fluid injector for inserting fluid into the housing, and a processor in communication with the imager and the sensor imaging module. The processor receives the sensory data and the captured images, and compares them to a. database to identify the characteristics of the substances.

A kit, system and method for positioning a camera assembly for automated visual inspection of at least one item, are provided. Provided are a camera assembly and a mounting assembly adapted to support the camera assembly wherein the mounting assembly is adapted for assembly and installation by an untrained user and wherein the installation can be guided by a planner application running on a computing device; such that the FOV of the camera assembly includes the item to be inspected.

A test apparatus can measuring particle plugging of a simulated fracture. The test apparatus can include a first test component having a first surface and a second test component having a second surface. The second test component can be positionable relative to the first test component to create a simulated fracture between the first surface and the second surface. The test apparatus can include a visualization area of at least one of the first test component or the second test component can be positioned between a fluid inlet and a fluid outlet along at least a portion of the simulated fracture.

An optical construction includes a first chamber including one or more first walls disposed inside a second chamber including one or more second walls. The first chamber includes a first top and an opposite closed first bottom. The second chamber includes an open second top proximate the open first top and an opposite second bottom proximate the closed first bottom. At least a portion of the one or more second walls includes a plurality of microlayers numbering at least 20 in total. The at least the portion of the one or more second walls faces, and is spaced apart by a non-zero gap from, a corresponding at least a portion of the one or more first walls. The non-zero gap is filled with a material having a lower index of refraction than at least an outermost surface of the at least the portion of the one or more second walls.

A cartridge to be installed in a detection device for detecting light generated from a measurement sample containing a test substance is provided. The cartridge includes: a plurality of detection chambers fluidly isolated from each other and each receiving a measurement sample; and a transmission suppression unit provided between one detection chamber and another detection chamber of the plurality of detection chambers, and configured to suppress transmission of light generated from a measurement sample in the one detection chamber to the another detection chamber.

Methods and systems are described herein for early detection of scaling during processing of liquid solutions. Particularly, the methods and systems described herein provide detection of the onset of scalant crystallization, so that measures can be deployed in a way that avoids significant scaling of membranes or other separating elements.

Disclosed herein is a system and method for quantitative detection and analysis of molecular binding kinetics of a substance with surface membrane proteins of a biological object, such as a live cell, based on detecting and tracking membrane fluctuation amplitude changes cause by membrane displacement associated with the binding of the substance with the surface membrane proteins. The molecular binding kinetics can be detected with high precision in real time from an optical image of the biological object with a differential detection method.
