Abstract
Abstract System for remotely monitoring the temperature of animals in which a capsule containing a variable length antenna which changes in length according to the animal''s temperature is embedded in the animal. Interrogating means are provided for transmitting a range of frequency signals to the capsule and for receiving reflected signals from the antenna. The system in addition has means for detecting a peak signal value from the antenna to indicate the animal''s temperature and to provide a read-out or display of the animal''s temperature.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A remote monitoring system for animal body temperature, comprising: a. a variable length antenna means for being subcutaneously implanted in an animal, said antenna means being such that its length variations are proportional to changes in the animal''s body temperature, b. a remote interrogating unit which transmits a range of radio frequency signals bracketing the range through which the length of said antenna may vary, said range of signals including one which will constitute a resonating frequency corresponding to the antenna length and to which the antenna will respond and transmit back to the interrogating unit a peak amplitude reflected signal, said unit including additional means for receiving said peak amplitude signal and converting the same to a visual read out of the animal''s body temperature.
Claim 2
Dependent Claim
126 words
A remote monitoring system for animal body temperature, comprising: a. a variable length antenna means for being subcutaneously implanted in an animal, said antenna means being such that its length variations are proportional to changes in the animal''s body temperature, b. a remote interrogating unit which transmits a range of radio frequency signals bracketing the range through which the length of said antenna may vary, said range of signals including one which will constitute a resonating frequency corresponding to the antenna length and to which the antenna will respond and transmit back to the interrogating unit a peak amplitude reflected signal, said unit including additional means for receiving said peak amplitude signal and converting the same to a visual read out of the animal''s body temperature.
Claim 3
Dependent Claim
28 words
The system according to claim 1 and wherein said interrogating unit includes a transmitter and receiver both of which are connected to and controlled by a frequency controller.
Claim 4
Dependent Claim
36 words
The system according to claim 1 and wherein said antenna means comprises a reservoir and capillary tube containing metallic powder in suspension in a carrier liquid and wherein the antenna is contained in a non-metallic capsule.
Claim 5
Dependent Claim
21 words
The system according to claim 1 and wherein said antenna means is a solid metal with a high coefficient of expansion.
Claim 6
Dependent Claim
59 words
An antenna for a remote monitoring system for animal body temperature, comprising: a. a variable length antenna means for being subcutaneously implanted in an animal, said antenna means being such that its length variations are proportional to changes in the animal''s body temperature, said antenna also being at least partially metallic in nature and encapsulated in a non-metallic substance.
Claim 7
Dependent Claim
59 words
An antenna for a remote monitoring system for animal body temperature, comprising: a. a variable length antenna means for being subcutaneously implanted in an animal, said antenna means being such that its length variations are proportional to changes in the animal''s body temperature, said antenna also being at least partially metallic in nature and encapsulated in a non-metallic substance.
Claim 8
Independent Claim
102 words
A method for remote monitoring of the body temperature of animals, comprising: a. implanting subcutaneously a variable length antenna in an animal which variations in length are directly responsive to the animal''s body temperature, b. transmitting a range of interrogating radio signals to said antenna to determine the length of said antenna, c. reflecting said signals from said antenna, d. receiving said signals in such a manner as to detect a peak amplitude reflected signal corresponding to a resonating frequency for the antenna length, and e. converting said peak amplitude reflected signal to a visual read out of the animal''s body temperature.
