Abstract: The present concept is a method of preparing an egg to determine the color of the egg using an egg yolk cover. The egg yolk cover is dome-shaped with a base edge and inspection area. The egg yolk cover eliminates ambient light from impinging on the egg yolk and is used in combination with a light sensor to determine the color of egg yolks. The light sensor includes a single flat printed circuit board with a top and bottom side which includes at least one LED light and one color sensor, at least one light pipe receiving light from the LED and transmitting it onto a substrate at an angle theta and a tube frame including an optical tube for receiving light reflections from the substrate. The light pipes and the tube frame are compression fit between the printed circuit board and a lower housing. To determine the color of the egg yolk, the egg is first cracked onto a flat surface. The egg yolk cover is then placed over the egg yolk and the color sensor is placed onto the inspection area to measure the color.

Abstract: A device and a method are provided for measuring the moisture in die cast molds, the cavity of which is connected via an evacuation conduit to an evacuation device. The modular assembly of the device is connectable to the evacuation conduit and includes a sensor assembly to measure the moisture of gases evacuated from the mold cavity. The sensor assembly includes an emitter emitting electromagnetic radiation and a detector detecting electromagnetic radiation. On the basis of the measured values obtained during the evacuation action it can be determined whether the amount of a water/release agent mixture jetted into the mold cavity needs to be altered before the actual casting action.

Abstract: Optical computing devices are disclosed. One optical computing device includes an electromagnetic radiation source that emits electromagnetic radiation into an optical train to optically interact with a sample and at least one integrated computational element, the sample being configured to generate optically interacted radiation. A sampling window is arranged adjacent the sample and configured to allow transmission of the electromagnetic radiation therethrough and has one or more surfaces that generate one or more stray signals. A first focal lens is arranged to receive the optically interacted radiation and the one or more stray signals and generate a primary focal point from the optically interacted radiation. A structural element defines a spatial aperture aligned with the primary focal point such that the optically interacted radiation is able to pass therethrough while transmission of the one or more stray signals is substantially blocked by the structural element.

Abstract: An absorption cell for microfluidic chemical analysis made from tinted or coloured polymers, for example polymethylmethacrylate (PMMA), in which microfluidic channels are cut. Light is coupled into the absorption cell via two windows (typically 200 um thick) that are retained at either end of the channel. Absorption is measured using a light source, such as a light emitting diode (LED) and a photodiode butted against the windows. Spurious scattered and/or reflected light is absorbed by the coloured polymer over the length of the measurement cell, while very little light loss occurs at the coupling windows.
