Abstract

An electromagnetic field deflecting garment made up of a dry knitted conductive fabric (2) with conductive filaments (3) disposed in parallel fashion, edged with a lattice conductive fabric (4) with filaments (5) disposed in a criss-crossed pattern, an electrical circuit (10) able to disperse the electromagnetic signal coming from the garment being connected to said fabric (4).

Claims

1. An electromagnetic field deflecting garment, comprising:

a conducting fabric edged with a lattice fabric having conductive filaments which serve to close a conductive circuit between said conducting fabric and said lattice fabric; and

an electronic circuit interconnected through a conductor to said lattice fabric, wherein said electronic circuit is operable to substantially completely dispel an electromagnetic signal coming from said garment through a Joule effect,

wherein said electronic circuit is a parallel resonator at a predetermined cutting frequency and predetermined resonance frequency.

2. A garment according to claim 1, wherein said conducting fabric is a knitted fabric with filaments consisting of conductive material disposed parallel to each other.

3. A garment according to claim 1, wherein said lattice fabric has filaments of conductive material disposed in a lattice wherein at least one filament of conductive material is arranged in a perpendicular orientation relative to the remaining filaments of conductive material.

4. A garment according to claim 1, wherein said parallel resonator consists of the connection in parallel of an inductance, a first and a second capacitance decoupled by a diode, and a resistance, said parallel resonator being coupled to the conductive fabric by means of a coupling capacitance.

5. A garment according to claim 4, wherein said inductance is about 10 μ

H, the first capacitance is about 20 pF, the second capacitance is about 10 μ

F, the diode is the model 1N32A, the resistance is about 2 MΩ and

6. A garment according to claim 1, wherein grounding of the electronic circuit is achieved by means of a cord protruding from the garment and made of conductive material.

7. A garment according to claim 1, wherein a microamperometer is connected to said electronic circuit allowing the intensity of the electromagnetic field absorbed by the garment to be displayed.

8. A garment according to claim 1, wherein said garment is a jacket.

9. A garment according to claim 8, wherein said jacket comprises a housing to hold objects, a housing to contain the microamperometer and a housing to contain the electronic circuit.

10. A garment according to claim 1, wherein said garment is a hat.

11. A garment according to claim 10, wherein said electronic circuit is positioned inside the hat.
