A system of spectroscopic devices deployed amongst the fluid infrastructure of hydrocarbon fluids are described herein. The devices provide early visibility into the characteristics of those fluids which inform and educate downstream parties of the potential value of the fluid, or the opportunity to reblend or redirect the fluid to optimize the formulization. By allowing downstream parties to determine the quality and quantity of refined products at an early stage, they are better able to determine the true value of the fluid. The data from the distributed network of spectroscopic analyzers provides valuation information that can be used to make more informed purchasing decisions or allow processors to create blends that optimize the efficiency of refining operations.

Hydrocarbon condensate detection and control. The hydrocarbon condensate detection and control system includes detecting hydrocarbon in an aqueous mixture by sensing fluorescence, turbidity, and color of the aqueous mixture and controlling the flow of the aqueous mixture based on the hydrocarbon content of the aqueous mixture.

An apparatus for manufacturing an electrode performs press-working of a strip electrode being conveyed. This manufacturing apparatus includes a press roll including a roll surface having a width that is twice or more a width of the strip electrode, a switch configured to switch a contact region of the roll surface contacting with the strip electrode during press-working, and a controller. When an abnormality of the roll surface is detected in a state where the contact region of the roll surface is a region located on the left side with respect to a center line of the roll surface, the controller controls the switch such that the contact region of the roll surface is switched to a region located on the right side with respect to the center line of the roll surface.

Systems and methods for monitoring emissions of a combusted gas are provided. The method includes determining a first net heating value of a flare gas. The method also includes determining a second net heating value of a combustion gas including the flare gas. The second net heating value can be determined based upon the first net heating value and a volumetric flow rate of the flare gas.

A combustion efficiency of the combustion gas can be determined using the selected model, the second net heating value, and selected ones of the process conditions and the environmental conditions. Total emissions of the combustion mixture can be further determined from the combustion efficiency and a volumetric flow rate of the combustion gas.

In certain embodiments, a system for making an implant for an eye comprises a printer, a camera, and a computer. The printer prints material onto a target and has a printer head and printer controller. The printer head deposits the material onto the target, and the printer controller moves the printer head to deposit the material onto a specific location of the target. The camera generates an image to monitor the printing of the material. The computer stores a pattern for the implant, which is designed to provide refractive treatment for the eye; sends instructions to the printer controller to move the printer head to print the material onto the target according to the pattern; assesses the image from the camera according to the pattern; and adjusts the instructions in response to the image.

A coating/developing device includes: a first laser unit that irradiates a coating liquid with laser light and acquires a state of the coating liquid based on a change in the laser light; and an irradiation propriety determination mechanism that determines whether the first laser unit irradiates the coating liquid with the laser light based on the coating liquid on a liquid bottle side of a position where the laser light is irradiated from the first laser unit in a flow path. The irradiation propriety determination mechanism includes: a second laser unit that acquires color information of the coating liquid; and a controller. The controller determines whether the color information of the coating liquid is predetermined color information that readily absorbs a wavelength of the light irradiated by the first laser unit and executes determining whether to irradiate the coating liquid with the laser light based on the determination result.

A method for 3D printing a part in a layer-wise manner includes providing a pool of polymerizable liquid in a vessel over a build window and positioning a downward-facing build platform in the pool, thereby defining a build region above the build window. The method includes selectively curing a volume of polymerizable liquid in the build region by imparting electromagnetic radiation through the build window to form a printed layer of the part adhered to the build platform and scanning at least a portion of the build window with monochromatic, polarized light along a plane of incidence. The method includes measuring a change in intensity and polarity of the light to obtain information about the printed layer. The method includes raising the build platform to a height of a next layer to be printed and modifying the electromagnetic energy imparted into the next layer based upon the obtained information to print a next layer. The imparting, scanning, measuring, raising and modifying steps are repeated until the part is printed.

A method of detecting a Facet region includes: a fluorescence luminance detecting step of detecting fluorescence luminance unique to SiC by irradiating a SiC ingot with exciting light having a predetermined wavelength from a top surface of the SiC ingot; and a coordinate setting step of setting a region in which the fluorescence luminance is equal to or higher than a predetermined value in the fluorescence luminance detecting step as a non-Facet region, setting a region in which the fluorescence luminance is lower than the predetermined value in the fluorescence luminance detecting step as a Facet region, and setting coordinates of a boundary between the Facet region and the non-Facet region.
