| 20080252877 | Inspection of Eggs in the Presence of Blood - The invention relates to a device for inspecting eggs for the presence of blood. The device comprises a light source in order to pass light at a first wavelength which is not selectively absorbed by blood and light at a second wavelength which is selectively absorbed by blood through an egg to be inspected. Furthermore, the device comprises detection means for converting the light transmission through the egg to be inspected for each of the two wavelengths into corresponding signals, each of the said signals being representative of the light transmission at the relevant wavelength. The device also comprises signal-processing means which are transmission associated with the first wavelength and the light transmission associated with the second wavelength based on the signals emanating from the detection means and to emit a decision signal which is representative of the decision whether or not an egg contains blood on the basis of this ratio. According to the invention, the light source comprises one or more identical LED's (Light Emitting Diode) for generating light which passes through the egg. In use the one or more LED's emit light within a certain narrow spectrum, which spectrum comprises both the first and the second wavelength. | 10-16-2008 |

| 20100002225 | Methods and Apparatus for Maintaining Effective Operation of Apparatus for Candling Avian Eggs - Egg candling methods and apparatus are provided wherein the optical path between a light source and light detector is monitored for obscuring debris and/or malfunctions. A method of candling eggs includes illuminating an egg with light from a light source; receiving light passing through the egg at a light detector; generating an output signal that corresponds to light received at the light detector for the egg; and analyzing the output signal to determine whether the optical path between the light source and light detector has been altered. In response to determining that a respective optical path has been altered, the light source and/or light detector is cleaned and/or inspected for malfunctions. Cleaning the light source and/or light detector may include wiping a surface of the light source and/or light detector and/or spraying a surface of the light source and/or light detector with a fluid. | 01-07-2010 |
| 20100026989 | Detection of Open Cracks in Eggs - A conveying device for conveying eggs comprises an endless conveyor provided with rollers extending transversely to the direction of conveyance. The rollers are arranged in pairs, and each pair of rollers forms an receiving space, in which an egg is accommodated in such a way that the egg rests on both rollers. The conveying device furthermore comprises a transfer device provided with a plurality of pick-up elements for picking up the eggs from a tray and placing the eggs on the conveyor. The pick-up elements on the transfer device can be moved from a first position in which they are positioned at a distance from each other corresponding to the distance between the individual eggs on the tray, viewed in the direction of conveyance, and a second position corresponding to the centre-to-centre distance between two receiving spaces. In use, the rollers are set in rotation, with the result that an egg resting on them is set in rotation, which is advantageous if the eggs on the conveyor have to be inspected for cracks. In this case by means of a plurality of lasers disposed in a stationary position one after the other a laser beam is directed at the egg during movement of the egg, and the light transmission of the egg surface is observed by optical observation means. Data processing means are equipped to decide on the basis of the observed light transmission whether or not an egg has a crack. | 02-04-2010 |
