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 a 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.

A hyperspectral method for detecting the present condition of an avian egg is disclosed in which a neural network algorithm is used to compare the spectrum of a test egg against a spectral library. The method can detect fertility with greater than 90% reliability on the day of laying and the gender of the chick with greater than 75% reliability on the 12th day after laying.

A system for measuring one or more physical properties of cementitious material is operable to cure a slurry of cementitious material under desired conditions of temperature and pressure. Particularly, the system may be operable to cure the slurry under a temperature and pressure expected to be experienced downhole. The system may also be used to determine properties of the cured cementitious material, such as maximum yield strength and shear bond strength at the desired temperature and pressure. The desired conditions of temperature and pressure may be applied both during curing and testing of the cementitious material.

Method and apparatus for producing vaccine within a plurality of eggs are provided. Each of a plurality of eggs (1) is illuminated with light from one or more LED's (24). A detector (26) is positioned adjacent each egg and detects light passing therethrough. Each egg is then identified as containing a live embryo or as being a non-live egg. Each egg that is determined not to contain a live embryo may be removed, either automatically or by hand. A seed virus is injected into each egg identified as containing a live embryo. After a predetermined period of incubation each live embryo is euthanized and amniotic fluid containing a vaccine produced as a result of the presence of a seed virus is harvested from each euthanized egg.

The invention relates to an egg candling method for determining the state of eggs between the third and seventeenth days, and in particular for determining the living or dead state of said egg. According to the invention, the egg is illuminated with a green or blue light for visually showing on the shell a shadow of the blood network supplying the embryo if the network is present in the egg. At least one image of the egg is acquired and processed in order to determine the vitality level of the egg based on the presence of said blood network or the lack thereof, and based on the size of the veins of said blood network if present. The method can also be used for characterising the presence or absence of an air space at the upper portion of the egg and thus defining the inverted or uninverted position of the egg. The method can finally be used for detecting lesions on the shell, and particularly cracked shells.

An X-ray inspection (10) apparatus includes an X-ray radiating part, an X-ray detecting part, a mass estimation unit and a mass class determination unit. The X-ray radiating part is configured and arranged to radiate X-rays to an inspection target (8). The X-ray detecting part is configured and arranged to detect the X-rays radiated from the X-ray radiating part that transmitted through the inspection target (8). The mass estimation unit is configured to estimate a mass of the inspection target based on an amount of the X-rays detected by the X-ray detecting part. The mass class determination unit is configured to determine which mass class among a plurality of mass classes (53a,53b,...53g,54) within a preset range the inspection target (8) belongs to based on the mass of the inspection target estimated by the mass estimation unit.

A device (1) for inspecting objects with a substantially spherical surface, such as for example eggs or fruit, comprises optical observation means (8) for observing the objects. The device has a supporting surface (10) for supporting the objects. There is a light source for illuminating the objects. The device also comprises a box (2) with reflective walls (3a, 4b and 4a shown) which is positioned above the supporting surface (11). The light source and the observation means (8) are accomadated in the box (2). A plurality of objects can be placed next to one another on the supporting surface (10) and can be illuminated equally well.
摘要:
The invention comprises a method for classifying poultry eggs, said method comprising the steps of: providing a plurality of eggs each having a respective physical egg location; measuring the temperatures of the eggs; and classifying the eggs as a function of the temperatures of the eggs. The step of classifying includes: determining a spatial temperature trend among the plurality of eggs; and identifying live eggs of the plurality of eggs using the spatial temperature trend. Optionally, the step of determining a spatial temperature trend includes generating a temperature trend map including a predicted egg temperature for each egg location and the step of classifying includes correcting the egg temperatures for relative egg locations and identifying live eggs of the plurality of eggs using the corrected egg temperatures.
