Abstract

An animal monitoring device configured as a bolus for oral administration to reside in the reticulorumen of a ruminant animal. The animal monitoring device includes a memory element, a processor in communication with the memory element and a computer code contained in the memory element. The computer code includes a power management module executable by the processor to regulate power use by the bolus based on determination of remaining energy stored in an energy source and the determined power requirements over a pre-determined life cycle of the bolus.

Claims

1. A method of monitoring the physiological parameters of a ruminant animal, comprising:

disposing a bolus in the reticulorumen of said ruminant animals;

enabling or disabling one or more sensors in said bolus by execution of a computer code contained in a non-transitory computer readable media communicatively coupled to a processor, said enabling or disabling of said one or more sensors coordinated with a plurality of life stages in a lifespan of said ruminant animal;

generating a sensor signal from said one of more sensors when enabled, where said sensor signal varies based on a corresponding change in one or more physiological parameters of said ruminant animal; and

transmitting encoded physiological data indicative of the physiological parameters of said ruminant animal.

2. The method of claim 1, wherein the step of enabling or disabling one or more sensors in said bolus is performed by operation of a power management module based upon a comparison of the sensor signal to a pre-determined set of one or more physiological parameters during said plurality of life stages in said lifespan of said ruminant animal.

3. The method of claim 1, wherein the step of enabling or disabling one or more sensors in said bolus further comprises assessing elapsed time from an activation of said bolus.

4. The method of claim 1, wherein said plurality of life stages in said life span of said ruminant animal comprise a first life stage prior to puberty and a second life stage commencing with puberty.

5. A method of monitoring physiological parameters of a ruminant animal, comprising:

generating a sensor signal from one or more sensors contained in a bolus orally administered to said ruminant animal, said sensor signal varies based on a corresponding change in one or more physiological parameters of said ruminant animal;

encoding said sensor signal from said one or more sensors as encoded physiological data corresponding to said one or more physiological parameters of said ruminant animal; and

storing said encoded physiological data in a non-transitory computer readable media,

enabling a radio signal generator located within said bolus;

activating said radio signal generator at pre-determined intervals to generate a radio signal to carry said encoded physiological data; and

generating said radio signal having a frequency of between about 700 MHz to about 1 GHz.

6. The method of claim 5, wherein said frequency is selected from the group consisting of:

between about 700 MHz to about 800 MHz, 750 MHz to about 850 MHz, about 800 MHz to about 900 MHz, 850 MHz to about 950 MHz, 900 MHz to about 1 GHz.

7. The method of claim 6, wherein said bolus further comprises matching elements which adjusts said frequency of said radio signal to compensate for a change in said frequency of said radio signal due to passing through a mass of said ruminant animal.

8. A method of monitoring physiological parameters of a ruminant animal, comprising:

determining a remaining amount of energy stored in a power source located within a bolus orally administered to said ruminant animal;

determining an amount of energy required by said bolus to operate through a pre-determined period of time based on current programming of a computer code contained in a non-transitory computer readable media contained in said bolus;

comparing said amount of energy required by said bolus to operate through said pre-determined period of time to said remaining amount of energy stored in said power source; and

calculating a difference in said amount of energy remaining in the power source and said amount of energy required by said bolus to operate through said pre-determined period of time; and

performing one or more power regulation events to offset said difference in said amount of energy remaining in the power source and said amount of energy required by said bolus to operate through said pre-determined period of time.

9. A method of monitoring physiological parameters of a ruminant animal, comprising:

generating a sensor signal from one or more sensors contained in a bolus orally administered to said ruminant animal, said sensor signal varies based on a corresponding change in one or more physiological parameters of said ruminant animal;

encoding said sensor signal from said one or more sensors as encoded physiological data corresponding to said one or more physiological parameters of said ruminant animal;

storing said encoded physiological data in a non-transitory computer readable media;
