Abstract

The present invention provides a bolus for introducing into a ruminant animal'"'"'s reticulum, comprising at least one pressure sensor (e.g. acoustic sensor and pressure transducer) configured and operable for receiving an overall pressure signal emanated by two or more signal sources in its surroundings and outputting a data stream indicative thereof; a processing utility for receiving and processing the data stream indicative of the overall pressure signal to isolate therefrom signal components from two or more defined sources and outputting one or more values indicative of a health condition of the animal; and a communication utility for receiving said one or more values and transmitting a signal corresponding thereto. The invention also provides a method for monitoring health condition of a ruminant animal and a system therefore, making use of the bolus of the invention.

3. A bolus according to claim 1, wherein said processing utility comprises a filtering module configured and operable for receiving an input data and isolating therefrom data corresponding to pressure signal from two or more defined pressure sources emanating from one or more of the heart, the respiratory system and the digestive system of the animal.

4. A bolus according to claim 1, comprising two or more different pressure sensors associated with respective two or more utilities of the processing unit running two or more respective algorithms, each for enhancing one signal component while attenuating all the other.

5. A bolus according to claim 3, comprising the single sensor and said filtering module comprising two or more different filters, each filter being configured and operable to isolate from the overall pressure signal a part including the respective signal component, to be processed by a respective algorithm in the processing unit to determine the required parameters.

6. A bolus according to claim 1, wherein the analyzed data stream corresponds to pressure signals recorded over a predetermined observation period of time T that is selected to be short enough to allow the heartbeat to be considered as quasi-stationary and long enough to permit an accurate and precise calculation of the heart rate.

7. A bolus according to claim 5, wherein the time T is about 8-15 seconds.

8. A bolus according to claim 1, wherein the processing unit includes a hardware utility configured and operable to receive said data stream indicative of the overall pressure signal, apply a frequency filtering thereto, and provide a digital signal representative of the filtered signal;

and a software utility preprogrammed to process the digital signal by applying thereto a root-mean-squared power windowing and inter-beat interval extraction to thereby obtain the one or more values indicative of the health condition of the animal.

9. A bolus according to claim 1, wherein the output of the processing unit includes data indicative of a unique ID assigned to the animal.

10. A bolus according to claim 1, wherein said signal generated by the communication utility is a two way radio-frequency signal.

11. A bolus according to claim 1, wherein said pressure sensor is an acoustic sensor for measuring acoustic signal.

13. A method for monitoring health condition of a ruminant animal, the method comprising:
