Abstract

ARRANGEMENT INTRODUCED IN A HIDDEN RECEIVER-SENDER DELIMITER FOR PNEUMATICS AND SIMILARS, especially a constructive arrangement allowing the use of a transponder (device to send and receive radio frequency signals) in aggressive means, be them chemical, mechanical or others, with no losses which may cause damage to said transponder; the conventional transponder (T) for emission and reception of radio frequency signals (RF) composed by a chip (1) and a coil reel (2); the transponder (T), with its new features, may be used, with no prejudice to its features, in aggressive chemical or mechanical means; the transponder (T) receives two protections: the first one by covering the transponder set (T) with a plastic film (F); the second protection is the introduction of said transponder (T), already with the first protection, inside a capsule (3) with special features, made of transparent material to electromagnetic waves and appropriate to resist against different mechanical efforts, be them twisting, flexion, traction or even mechanical vibrations, being the employed material preferably a plastic provided not only with transparence to electromagnetic waves, but also relative flexibility.

Claims

1. A transponder for the emission and reception of radio frequency signals comprising, a chip and a coil reel, a plastic film covering, said chip and said coil reel, said transponder thus covered, being housed between male and female portions of a capsule, said female portion comprising a compact base connected to an equally compact side forming a smooth end rim, the internal wall of said compact side has an edge with a configuration comprising a small straight path, distal from said compact base, followed by a “

V”

, shape indentation followed by a retracted bottom housing which has its width limited by a ring wall, said ring wall extends up about the vertex of said “

V”

indentation, with said ring wall having a bevel on the side of the male portion and rounded edge on the other side;

the bottom of said compact base is located at a level above the retracted bottom;

the male portion comprises a compact top whose diameter is substantially compatible with the straight path of the female portion, with said top comprising an attachment portion, comprising a correspondence straight path followed by a “

V”

-shaped projection which is coupled and fits under relative pressure to the “

V”

shaped indentation of the female portion, while an equally ring-shaped rim is settled over the retracted bottom, so to be restrained by the ring wall;

said male and female portions become fitted between them under considerable pressure;

a chamber is created between the bottom of the compact base and the maximum height of the ring wall, coinciding with the bottom of the compact top, inside which the transponder is housed, with a diameter adjustment existing in said chamber very near to the internal diameter of the ring wall.

2. The device of claim 1, wherein said chamber has dimensions to allow the covered transponder to fit under pressure, forming smooth arching determining a “

spring”

effect having the purpose to avoid the transponder to absorb vibration, as well as the random balance of inside capsule and, in case of huge twisting or impact over the capsule, the transponder does not happen to deform.

3. The device of claim 1, which is employed in aggressive chemical or mechanical means, with no prejudice to the functions of the transponder, since it presents double protection;

the first one from the cover by the plastic film or similar immersion or any other form allowing said resource and being able to quickly dry chemical and mechanical insulation; and

the second one through the capsule made of transparent material to electromagnetic waves and appropriate to resist against various mechanical efforts, be them twisting, flexion, traction or even mechanical vibrations, being the employed material preferably a polycarbonate provided not only with transparence to electromagnetic waves, but also relative flexibility.

4. The device of claim 1, in which the covering, allows the transponder to respond, in a fully efficient way, to the use in naturally aggressive chemical means, including acids.

5. The device of claim 1, in which said capsule is formed of transparent material to electromagnetic waves and appropriate to resist against mechanical efforts.

6. The device of claim 5 in which the chamber has dimensions to allow the covered transponder to fit under pressure, forming smooth arching determining a “

spring”

effect having the purpose to avoid the transponder to absorb vibration, as well as the random balance inside the capsule and, in case of huge twisting or impact over the capsule, the transponder (T) does not happen to deform.

7. An electrical device for transmitting or receiving electric signals, comprising:

A transponder;

a film, coating said transponder;

a thin capsule, enclosing said film coated transponder within a chamber, said capsule comprising;

a base portion; and

a top portion, said top portion securely interlocking with said base portion to form the chamber, said chamber being of a size as to cause the transponder to form an arch within the chamber, said transponder fitting snugly in the chamber between the base portion and the top portion to prevent damage from vibration.

8. The device of claim 7, wherein said base portion further comprises:

a platform for said transponder;

a ring wall around said platform; and

a side wall around an edge of said base portion; and

wherein said top portion further comprises;

a cover portion; and

an attachment wall, said attachment wall structured and arranged to fit snugly between said ring wall and said side wall of said base portion.

9. The device of claim 8, further comprising:

a groove on an interior side of said side wall; and

a protrusion on an exterior side of said attachment wall, said protrusion structured and arranged to mate with said groove in a manner that snugly secures said top portion to said base portion.

10. The device of claim 9, wherein said groove extends along a middle portion of said side wall.

11. The device of claim 8, wherein said attachment wall extends below said platform when said top portion and said base portion are secured to each other.

12. The device of claim 7 wherein said transponder comprises a chip and a coil reel.

13. The device of claim 7, wherein said film is formed or a substance which prevents said transponder from being damaged by chemicals, including acids, while not interfering with said transponder'"'"'s functionality.

14. The device of claim 7, wherein said film is plastic.

15. The device of claim 7, wherein said capsule is formed of a material that does not interfere with electromagnetic waves and is strong enough to resist forces associated with twisting, flexion, traction or even mechanical vibrations.

16. The device of claim 7, wherein said capsule is formed of a polycarbonate provided not only with transparence to electromagnetic waves, but also relative flexibility.
