The detector of the photon intensity is either a low light sensing photomultiplier tube (PMT), silicon based photon counting sensor, or Geiger-mode avalanche photodiode detector. The detector of the photon spectrum is a spectrometer. Following exposure to the referenced light sources, fertile avian eggs will exhibit a higher intensity of photons than that of unfertilized avian eggs, and avian eggs of the female gender will emit a different spectrum of photons than will avian eggs of the male gender.Type: GrantFiled: January 17, 2009Date of Patent: May 31, 2011Inventor: Jack Dean Rollins

Publication number: 20110067633Abstract: An in-ovo egg injection machine generates and transmits vibration to an incubating egg tray to align the egg axes prior to injection. The mechanism can be used independently of the in-ovo egg injection machine and is suitable for use with an egg candling machine. With the eggs positioned on the incubating tray and held by egg tray posts with their large ends facing upward for the purposes of incubation, vibration is applied to the tray. The vibration allows the eggs to ‘float’ in their restricted locations in the egg tray. Since the eggs are naturally bottom-heavy, the heaviest portion of each egg moves down as the tray is vibrated. The eggs therefore self-align their axes into an orientation corresponding with the established vertical axes of the injectors, respectively, with no contact with the eggs being required.Type: ApplicationFiled: January 23, 2009Publication date: March 24, 2011Inventors: Rafael S.

Publication number: 20080202427Abstract: A pneumatically operated egg injection machine includes a sealed frame structure with a pair of in line parallel tracks through an injection section and a transfer section in series. An injection assembly includes a plurality of injectors gripped in a support plate to simultaneously inject vaccine into the same injection region irrespective of egg height and orientation. Fluid delivery systems meter prescribed vaccine dosages to the injecting needles with reduced turbulence, friction, heat and residence time to increase the delivered titer to the injected eggs. A transfer assembly lifts the injected eggs by causing a reduced pressure around the injection hole while maintaining the injection hole at atmospheric pressure. The injection assembly is sprayed with a sanitizing solution at the same time that the injected eggs are moved from the injection section to the transfer section.Type: ApplicationFiled: December 28, 2007Publication date: August 28, 2008Inventors: Rafael S. Correa, Marco A. Quiroz, William D. Samson, Erich F. Bevensee

Publication number: 20080149033Abstract: Egg candling methods and apparatus are provided wherein non-live eggs, inverted egg, and side air cell eggs can be quickly identified. A method of candling eggs includes exposing a plurality of incubated eggs to an environment having a temperature different from a temperature at which the eggs were incubated; obtaining a thermal image of the eggs; and analyzing the thermal image to obtain surface temperature information for each egg. The surface temperature information is utilized to designate each egg as live/non-live, inverted, or having a side air cell.Type: ApplicationFiled: December 21, 2006Publication date: June 26, 2008Inventors: John H. Hebrank, Monika Garrell

Patent number: 7360500Abstract: An injection apparatus for injecting eggs of varying sizes and different orientations in an incubating tray that includes a substantially horizontal support plate with vertical openings therethrough, and vertical injectors resting in the openings and able to slide therein with respect to the plate such that the injectors can move vertically in the openings while remaining engaged with the support plate so as to maintain their vertical orientation throughout an injection sequence. For each opening, an expandable ring is positioned in the plate and pneumatically expanded to tighten around its respective injector after the injector has adjusted vertically in its respective opening to the height of an associated egg in order to maintain the injectors in their vertical orientation for injection of their associated eggs.Type: GrantFiled: April 10, 2006Date of Patent: April 22, 2008Assignee: AviTech, LLCInventors: Rafael S.

Patent number: 7333187Abstract: Identifying live eggs includes: a) illuminating eggs with light; b) receiving light passing through each egg at a light detector; c) generating an output signal that corresponds to light received at a light detector for each respective egg; d) analyzing the output signals to identify an indication of an external disturbance; e) analyzing the output signal for each egg to identify the existence of an embryo heart rate and/or embryo movement; and f) designating an egg as a live egg in response to identifying embryo heart rate and/or embryo movement. Steps a) through d) are repeated if output signals from a predetermined number of eggs contain an indication of an external disturbance to the eggs. Steps a) through f) are repeated if the number of eggs designated as live exceeds an expected number, or if embryo movement occurs at about the same time in a predetermined number of eggs.Type: GrantFiled: September 1, 2005Date of Patent: February 19, 2008Assignee: Embrex, Inc.Inventor: John H.

Patent number: 7261053Abstract: An in ovo jet injection apparatus and related methods for treating live eggs. The jet injection apparatus includes one or more jet injection delivery devices configured to deliver one or more treatment substances to predetermined areas of eggs using a high pressure stream of the treatment substance(s). Multiple treatment substances can be delivered so that they are spatially and/or temporally separate. The devices and methods of the invention enable the effective use of a plurality of treatment substances, including those that are effective when used alone but can be noxious if mixed. The methods and apparatus for the jet injection of substances into embryonic chicks reduce the risk of mechanical injury to the developing birds that would be caused by injection needles. The methods and apparatus of the invention can also reduce the introduction of an infection into the chicks.Type: GrantFiled: April 1, 2005Date of Patent: August 28, 2007Assignee: Merial LimitedInventors: Kemal Karaca, David J. Hayzer, Joseph H. Johnston, Jr.
