| 20080231534 | Multiple Phase Shifter for Protecting Individuals Against Electromagnetic Waves - The invention relates to a multiple phase shifter for protecting individuals against electromagnetic waves. The invention comprises several phase shift modules which each comprise two identical or homothetic flat loops which are electrically connected by means of two inter-loop connection elements at a first opening in each of the loops and which are electrically insulated from one another with the exception of the inter-loop connection elements. Each module is electrically connected to another module by means of two inter-module connection elements and is essentially identical or homothetic to the other modules. The inter-module connection elements connect one of the loops of one module at a second opening in the loop to one of the loops of another module at a second opening in said loop. The modules are electrically insulated from one another with the exception of the inter-module connection elements. | 09-25-2008 |
