In accordance with embodiments, there are provided devices, systems and methods for capturing images of one or more substances in a scene, such as toilets using an illumination module and an imaging module included in a housing wherein the housing is configured to be inserted to devices such as toilet cleaning devices and receive the one or more substances. The imaging module comprising one or more high quality imagers configured to capture one or more images or an image video of the substances and a processor for analyzing the captured images to identify the characteristic and/or type of the substances.

The present disclosure relates to gastrointestinal (GI) tract detection methods, devices and systems.

Provided is an apparatus for extracting water from a condenser to the outside for water quality analysis. The apparatus includes an insertion pipe inserted into a condenser, a screw thrust portion including a rotating shaft inserted into the insertion pipe, a screw coupled to one end of the rotating shaft, and a screw thrust portion comprising a power providing portion configured to transmit power to the rotating shaft, and an exhaust pipe provided in the insertion pipe to introduce the water to flow to the outside of the condenser when the water contained in the condenser flows toward a rear side of the screw according to a rotation of the screw.

An electrically passive device and method for in-situ acoustic emission, and/or releasing, sampling and/or measuring of a fluid or various material(s) is provided. The device may provide a robust timing mechanism to release, sample and/or perform measurements on a predefined schedule, and, in various embodiments, emits an acoustic signal sequence(s) that may be used for triangulation of the device position within, for example, a hydrocarbon reservoir or a living body.

An onboard apparatus, system, and method for automatically loading into or unloading from a bulk transport or other container and evaluating characteristics of a liquid during the loading or unloading, that dynamically monitors and evaluates characteristics of the flow, particularly density, which are used to determine other characteristics and values of the load, namely, presence of contaminants such as water, solids, out of specification conditions, etc. to enable accurately measuring volume, mass, and/or quality of the load, and optionally to automatically responsively perform certain operations, for example, to signal an operator, cease loading, segregate and/or return all or portions of the load, if contaminated or out of specification, and which facilitates control remotely, as well as for qualifying for government certification for custody transfer.

A system and method for sampling of liquid products. The system includes a portable, releaseably connected product sample receiving assembly and a plurality of product sampling and mixing assemblies. The product sample receiving assembly can be attached and detached from two or more the product sampling and mixing assemblies, so that a single product sample receiving assembly can be used to service multiple product sampling and mixing assembly locations at different times. Each of the multiple product sampling and mixing assemblies includes a suction assembly and a discharge assembly on opposite sides of a static mixer. The product sample receiving assembly may include a slip-stream configuration or in-line configuration. The product sampling and mixing assemblies may be unidirectional or bidirectional.

A device for collecting multiple samples for use by a single user while avoiding cross-contamination under adverse conditions is disclosed. A multiple sampling device comprising a single handle actuator with a trigger, connected to a shaft assembly further connected to a claw assembly for actuating a self-sealing sampling sphere in the process of collecting a desired sample, is disclosed. The sampling sphere comprises two halves that separate when the trigger and claw assembly are actuated, and close together when the trigger is released using springs on the claw assembly and sampling sphere. Additional sampling spheres are stored on the shaft assembly. In operation, once a sample is collected by one sampling sphere, the sampling sphere is exchanged with an empty sampling sphere stored on the shaft assembly.

Methods of evaluating viscous compositions are disclosed. These methods may be used to evaluate volumetric properties of fluids including peanut butter. The methods may include preparing a surface for testing by leveling and flattening a viscous composition, placing a drop of a liquid on the flattened leveled surface, evaluating the observed contact angle between the drop and the surface, and then comparing the observed contact angle to a reference contact angle.

Devices and methods for collecting trace amounts of samples are provided. A device can utilize a sterile syringe integrated with a venturi-type vacuum source for sample collection. The device can be used in a variety of applications for collecting specimens that are otherwise difficult to retrieve using conventional sample collecting techniques.

A fluid sample collection system for directly collecting a fluid sample from a fluid source includes a fluid collector and a fluid line. The fluid collector includes (i) a sample vial including a sample vial body and a vial cap that is selectively coupled and sealed to the sample vial body; (ii) a collector body that defines a passenger vial chamber, the sample vial being positioned at least partially within the passenger vial chamber during collection of the fluid; and (iii) a cap access facilitator that is configured to engage a portion of the sample vial to enable a user to selectively couple the vial cap to the sample vial body to seal the sample vial so that the fluid is retained within the sample vial. The fluid line extends between the fluid source and the fluid collector to substantially directly transmit the fluid sample to the fluid collector without exposing the fluid sample to the ambient environment that surrounds the fluid sample collection system.
