Abstract
Abstract A device for flexibly encasing electronic circuitry, where an electronic circuit is enclosed in a casing which includes a laminate consisting of metal and plastic sheets such as to form a diffusion impervious and electrically conductive structure which prevents harmful substances from reaching the electronic circuit and also prevents inductive electromagnetic exchange. Electrical conductors pass through the joint region of the laminate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A device for flexibly encasing an electronic circuit to prevent the electronic circuit from coming into contact with harmful substances present in the ambient environment, and for preventing undesirable exchange with induced electromagnetic fields, comprising an impervious casing comprising a metal and plastic laminate, and wherein the metal has a thickness which renders the laminate impervious to diffusion and capable of attenuating electromagnetic, radiofrequency radiation, and wherein the laminate has integrated therein electric conductors in the form of conductive paths printed in the metal and which can be electrically connected to the electronic circuit.
Claim 2
Independent Claim
94 words
A device for flexibly encasing an electronic circuit to prevent the electronic circuit from coming into contact with harmful substances present in the ambient environment, and for preventing undesirable exchange with induced electromagnetic fields, comprising an impervious casing comprising a metal and plastic laminate, and wherein the metal has a thickness which renders the laminate impervious to diffusion and capable of attenuating electromagnetic, radiofrequency radiation, and wherein the laminate has integrated therein electric conductors in the form of conductive paths printed in the metal and which can be electrically connected to the electronic circuit.
Claim 3
Dependent Claim
24 words
A device according to claim 1, wherein the laminate and the electric conductors are each connected to a respective joint region by fusion welding.
Claim 4
Dependent Claim
20 words
A device according to claim 1, wherein the laminate and the electric conductors are glued to their respective joint regions.
Claim 5
Dependent Claim
21 words
A device according to claim 1, wherein the laminate and the electric conductors are mechanically clamped to their respective joint regions.
Claim 6
Dependent Claim
21 words
A device according to claim 1, wherein a part of the casing is joined to a material other than the laminate.
Claim 7
Dependent Claim
18 words
A device according to claim 1, wherein a part of the casing is joined to the electronic circuit.
