1. An apparatus for detecting a drop of follicle fluid falling into a test tube, the apparatus comprising:
a test tube for storing follicle fluid, wherein the test tube has a cork fitted at open-end of the test tube, and wherein the cork has a passage allowing an inlet tube, carrying the follicle fluid, to pass through the test tube; a pair of optical devices positioned at an opposite side of the test tube, wherein the opposite side indicates a position on the test tube where an incoming follicle fluid flow breaks into a drop and detaches from the inlet tube, and wherein the pair of the optical devices comprises a first optical device and a second optical device, and wherein the first optical device emits a beam of light of a pre-defined intensity, through the test tube, towards the second optical device; and a signal processing circuitry, coupled with the test tube, to detect first and subsequent drops of the follicle fluid by
monitoring an intensity of the beam of light received by the second optical device,comparing the intensity of the beam of light with the pre-defined intensity, anddetecting the first and subsequent drops of the follicle fluid in the test tube when a difference between the pre-defined intensity and the intensity is greater than a pre-defined threshold value. |
