There is a system for user skin color determination of a user, the system comprising a skin analysis assembly, configured to obtain a user skin image of the user, comprising one or more user skin image pixels, perform color processing on the user skin image to determine a user skin color; and output the result of the color processing, the result comprising the user skin color.

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.

A modular housing for a spectrometer, the housing comprising at least two modules, the housing further comprising: a sensor recess configured to receive a sensor, the sensor being configured for determining at least one light spectrum characteristic of light received after optical interaction of the light with a sample; an aperture configured for receiving and guiding the light received after the optical interaction along a reception path extending from an entrance of the aperture to the sensor recess; and at least two channels configured for guiding and emitting light out of the modular housing, such that the light, after the optical interaction with the sample, is received at the entrance of the aperture; wherein the at least two channels are arranged along intersecting or skew axes; and wherein at least two of the at least two modules comprise respective ones of the at least two channels.

In some aspects, a device for apportioning granular samples includes a sample feeder defining a conduit, the conduit including a first opening to receive the granular samples and a second opening. The device includes a shuttle operably coupled to the sample feeder to receive the granular samples from the conduit via the second opening. The shuttle is configured to apportion the granular samples to incrementally enter a sample chamber to be analyzed. The device includes an outlet conduit fluidly coupled to the sample chamber and configured to permit the sample chamber to be evacuated.

A system and method for detecting colored objects and decoding messages are provided. A light source is operatively coupled to a power source for emitting light on a colored object. A light receiver is configured to receive the emitted light from the light source as the light reflects off the colored object and is further configured to detect color of the reflected light. Further, a processor is operatively coupled to processor readable media and is configured to receive, via a communications module, information representing the color of the reflected light. A housing is included for supporting the light source, the light receiver, the processor and the communications module. The processor is configured to process the information representing the color of the reflected light and provide at least partial message information corresponding to the color.

A portable color measurement device 10 is described. The device 10 has a body 20 including a light source 30 and a sensor 40. The body 20 includes a measurement zone 21 to accommodate, within the body 20, an element 100 to be measured for color. The light source 30 is configured to emit light along a path within the body 20 to the sensor 40. The measurement zone 21 is substantially in the path. The portable color measurement device is configured to measure properties of an accommodated element 100 in dependence on one or more outputs of the sensor 40.
