A mold sensor is configured with an enclosed chamber in which a nutrient-treated substrate is positioned. The mold sensor includes an optical sensor that is configured to measure optical properties in the enclosed chamber. A controller operates the optical sensor and is programmed to detect a presence of mold growing in the chamber based on the optical properties measured by the optical sensor.

The present invention provides a wide-area sample-based reader design which serves as a diagnostic detection device for bio-particles.

Provided herein is a collection device for collecting nano particles conveyed in a fluid including: a fluid duct having a fluid inlet and a fluid outlet, a fluid propelling element propelling said fluid through the fluid duct, and a collection element which is arranged in said fluid duct for the collection of nano particles conveyed in said fluid. The collection element includes a collection surface and an enhancement structure arranged in connection with the collection surface. The nano particles are deposited in the region of said collection surface and said enhancement structure and the collection surface with the enhancement structure enhances the spectral properties of said nano particles for a facile analysis of the amount of collected nano particles.

A mold sensor is configured with an enclosed chamber in which a nutrient-treated substrate is positioned. The mold sensor includes a sensing system that is configured to measure properties of pressure waves within the enclosed chamber. A controller operates the sensing system and is programmed to detect a presence of mold growing in the chamber based on the characteristics of the pressure wave response within the chamber.

A mold sensor include a housing that defines an enclosed chamber in which a nutrient-treated substrate is positioned. The mold sensor includes a substrate advancement mechanism that is configured to selectively move the substrate to expose a surface of the substrate within the chamber. The mold sensor includes a sensor configured to detect mold growth on the substrate within the chamber.

An analyzing apparatus includes an X-ray measurement device, an optical characteristic measurement device, and a calculation unit. The X-ray measurement device may be configured to measure fluorescent X-rays generated from the measurement object. The optical characteristic measurement device may be configured to obtain optical characteristics other than the fluorescent X-rays of one or more carbon compounds contained in the measurement object. The calculation unit may be configured to calculate information about a quantity of the one or more carbon compounds contained in the measurement object on the basis of the optical characteristics of the carbon compound(s), and correct the information about fluorescent X-rays measured by the X-ray measurement device on the basis of the information about the quantity of the carbon compound(s).

Embodiments described herein relate to a cleaning device and methods for cleaning an object. In one embodiment, the object is cleaned by moving a clean head along a surface of the object. Supercritical carbon dioxide fluid is delivered by supercritical carbon dioxide fluid vessel to the surface of the object. The supercritical carbon dioxide fluid and contamination material are removed from the object by a vacuum pump to a detector. One or more measurements of the contamination material are determined by the detector. Samples of the contamination material are collected by a collector. A contamination level of the surface of the object is determined by an analyzer.

A fuel filter inspection method includes capturing an image of a fuel filter sample using an imaging device and sending the captured image to an image processor. The method further includes the image processor receiving the captured image, thresholding the captured image to generate a binary image, determining sizes for a plurality of particles present in the binary image, comparing the size of each of particle of the plurality of particles to a particle size threshold, and quantifying the number of particles of the plurality of plurality of particles with a size greater than the particle size threshold. The method further includes the image processor comparing the number of particles of the plurality of particles with a size greater than the particle size threshold to a particle count threshold, and modifying a graphical user interface to indicate a state of the fuel filter sample based on the comparison.

A benchtop device flow setup for determining the effectiveness of magnetic treatment of feed water for reducing mineral scaling includes two similar branches, both equipped with a reverse osmosis membrane and a pump that operate in the transient regime at the same flow rate and transmembrane pressure. The flow setup is further fed with a solution at the same level of supersaturation measured in a stirred reactor, however, only one branch exposes the feed to a magnetic field.
