Abstract

A coupling method and device for an animal mountable electronic package is disclosed which is particularly useful for antenna implementation. A conductor is passed through a magnetic core having a coil wound thereon so that a magnetic path circuit is established to thereby cause a transformer action to be provided between electronic currents flowing in the coil and conductor, this magnetic path circuit, when established, being the coupling mechanism between coil and conductor. The conductor can be of any appropriate length to form a loop, dipole, monopole, or other type of antenna element. If the conductor ends are fastened together to form a closed loop (whether electrically closed or not), this resulting loop can be conveniently utilized for attaching the electronic package to an animal, such as, for example, by placing the loop around the animal'"'"''"'"'s neck, and when so utilized the loop is received within the core so that the electronic package is movable with respect to the loop antenna. A tube is also preferably provided to receive the conductor therein and reduce wear and breakage.

Claims

1. An animal mountable device having low vulnerability to breakage, said device comprising:

a tube;

a conductor extending through said tube and being freely movable relative thereto;

a magnetic core fastened around said tube;

a coil fastened to a portion of said magnetic core to establish coupling capability between said coil and said conductor, said coil being connected with predetermined electronic circuitry; and

means to fasten the ends of said conductor together to form a loop antenna about a predetermined portion of an animal, said conductor supporting said tube having said core fastened thereto so that said tube is freely movable along said conductor without adversely affecting signal coupling between said conductor and coil.

2. The device of claim 1 wherein said device includes a casing for packaging said tube, magnetic core, coil and electronic circuitry whereby said conductor extends through said casing so that said casing is movable along said conductor.

3. A method for coupling signals between animal mounted electronic circuitry and an antenna, and for supporting said electronic circuitry on said animal, said method comprising:

providing an antenna wrapped around a predetermined portion of an animal;

providing a magnetic core through which said antenna extends so that said magnetic core is supported by said antenna but is freely movable relative thereto;

maintaining spacing between said core and antenna so that wear is reduced as said core is moved along said antenna in axially opposite directions and rotated with respect thereto; and

providing a coil wrapped about said core so that a magnetic circuit path is established between said antenna and said core despite movement of said core with respect to said antenna.
