Methods and apparatus for identifying live eggs by detecting embryo heart rate and/or motion

Image Number 10 for United States Patent #6860225.

Methods and apparatus for identifying live eggs utilize a cup having a photodetector therewithin that overlies a portion of an egg. The egg is illuminated via a light source positioned adjacent the egg. Variations in the intensity of light passing through the egg is detected via the photodetector which generates an output signal corresponding to detected light intensity. The output signal is processed to identify cyclical and non-cyclical variations in light intensity. The egg is designated as a live egg in response to identifying cyclical and/or non-cyclical variations in light intensity.
