  • Patent number: 11293875
    Abstract: A micro-colorimetric sensor for sensing target chemicals that converts time sequence information into a spatial distribution of color. By tracking the spatial color distribution, chemical exposure over time is thus detected, which overcomes the limitation of traditional colorimetric sensors. A porous media is coated on a top surface of the substrate. Multiple sensing chemicals are fused in parallel linear channels into the porous media coating. A plate is affixed over the substrate top surface to cover the plurality of parallel linear channels. An air sample is diffused along the porous media to get a clear pattern of spatial color distribution and color images are captured. Optical parameters like gradient of spatial color distribution, intensity, and absorbance, etc., can be tracked to calculate analytes concentrations.

  • Patent number: 10739241
    Abstract: A method is for determining information about liquid droplet fallout during operation of a gas-liquid flare apparatus. The method includes disposing a plurality of tiles in a spaced apart fashion over a monitoring area. A gas hydrocarbon fuel is injected into the gas-liquid flare apparatus to create a combustible flow, and a test fluid is injected into the gas-liquid flare apparatus such that the test fluid is dispersed into the combustible flow. The combustible flow is combusted in in the gas-liquid flare apparatus, resulting in fallout of liquid droplets of the test fluid onto the plurality of tiles. Images of the liquid droplets on the plurality of tiles are analyzed so as to determine the information about liquid droplet fallout in the monitoring area, using a computer.

  • Patent number: 9983089
    Abstract: A persistent color change liquid indicator includes a backing layer, a penetration layer, and a reaction layer. The backing layer has an indication color. The penetration layer includes a liquid structure to allow a liquid to travel through the penetration layer to the reaction layer. The penetration layer is opaque when dry and translucent when exposed to the liquid is to allow the indication color to be visible. The reaction layer reacts to the presence of the liquid such that the visibility of the indication color persists after exposure to the liquid ceases.

  • Patent number: 9939431
    Abstract: A self-contained apparatus and methods for detecting the presence of any specified substance in any medium. A sample of the medium is placed in a capsule, along with a solvent and a sensor configured to test for a target analyte. The solvent comes into contact with the medium in the capsule, and the capsule is agitated to create a dispersion in the solvent of a portion of any target analyte present in the medium. A release mechanism configured to cause conduction of the dispersion to the sensor, so that the sensor produces an indication of presence of the target analyte if the target analyte is present in the medium. The apparatus uses a disposable capsule where the medium in question is placed and the disposable capsule is placed inside a reader and analyzed for presence of the harmful substance.

  • Patent number: 9915638
    Abstract: A food expiry label includes a layer of material (such as a water-swollen mammalian gelatine) that undergoes a phase transition (such as from solid to liquid) upon exposure to bacteria or fungi that result in food spoilage. The label may incorporate a tactile surface that the user can feel underneath the layer of gelatine once the gelatine has changed from solid to liquid. Thus a user can detect when a foodstuff is likely to have spoiled or been on the shelf for a predetermined period simply by feeling the label.

  • Patent number: 9915636
    Abstract: A reaction carrier (14), a measuring device (12) and a measuring method measure a concentration of gaseous and/or aerosol components of a gas mixture. A flow channel (42), extends between two connecting elements (44) and defines a reaction chamber (46) with an optically detectable reaction material (48) that reacts a component of the gas mixture or with a reaction product of the component. The reaction carrier (14) includes a temperature-measuring element (88). The measuring device (12) includes a temperature-measuring element (90) which records a temperature of the measuring device (12) and/or of the reaction carrier (14), and a temperature-determining unit (92) which determines the temperature of the gas mixture as a function of the measurement result of the at least one temperature-measuring element (90). The measuring method includes determining a concentration of the component on the basis of an optically detectable reaction and the determined temperature of the gas mixture.

  • Patent number: 9759648
    Abstract: Herein, a polymer-based device capable of lifting many times its own mass was fabricated by drying a solution of the polycation poly (diallyldimethyl ammonium chloride) (pDADMAC) on a surface coated with charged poly (N-isopropylacrylamide)-based microgels. Due to strong polymer-polymer and polymer-surface interactions, when the pDADMAC solution dries on the microgel-modified surface, it bends. If the surface is flexible, it curls up into a scroll like structure, that can be opened up at high (ca. 80%) humidity. This process is fully reversible, i.e., if the humidity is decreased, the surface curls back up. This expansion/contraction behavior is capable of lifting relatively large masses, many times its own mass, and can potentially be used as an artificial muscle.
