Abstract: A test cartridge for use in sample analysis is provided. The test cartridge includes a reservoir card that further includes a reagent that includes living biological cells; and a test cartridge base configured to accept the reservoir card. The reservoir card is configured to interface with a test cartridge base through at least one fluid port. The test cartridge base includes an elliptical reaction chamber having a central axis and an inlet channel connected to the reaction chamber. The inlet channel is positioned above the reaction chamber at an angle of 15-60 degrees above the horizontal and is offset from the central axis of the reaction chamber. Upon introducing a sample to be analyzed into the test cartridge base through the inlet channel, the sample is homogeneously mixed with the reagent while minimizing damage to the living biological cells.

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: An LED inspection lamp has plurality of LED sources for emitting electromagnetic radiation at different peak wavelengths for causing visible fluorescence in different leak detection dyes. A lens is associated with each LED. Radiation passing through lenses is superimposed in target area at target distance. Another LED inspection lamp has plurality of LEDs emitting electromagnetic radiation at a peak wavelength. A lens adaptor has lens housing for attachment to LED inspection lamp with a single LED for causing visible fluorescence, and a lens. Substantially all of the radiation from the LED passes through the lens and is focused in a target area at a target distance from the lenses. LED spot lights have a similar configuration. The LEDs may produce white light from distinct LEDs or from white LEDs. The light may be a flashlight or fixed spot light.
