Automatic detector of pregnancy in horses, cattle, sheep and goats.

摘要

"Automatic detector of pregnancy in horses, cattle, sheep, and goats".Patent of invention for diagnostic equipment automatic pregnancy in equ00b3inos, bovine, ovine and caprine animals which is obtained through the following process: digitization of the signal (3),4) from a Doppler transducer placed inside the animal via digital rectal examination: pre digital processing of sampled signal (5) through moving average filters for noise reduction;Digital processing of the signal (6) using the Hilbert transformation to obtain the envoltu00f3ria signal and Fourier transform (FFT) to obtain the spectrum of frequ00b3u00eancia signal; andFinally, the automatic diagnoses of pregnancy through neural networks (7).
