Floor covering for transmitting electromagnetic energy
Abstract
Abstract A FLOOR COVERING FOR TRANSMITTING ELECTROMAGNETIC ENERGY IN THE FORM OF SIGNAL ENERGY OR ELECTRICAL POWER OR BOTH, THE ENERGY BEING RECEIVED AT ONE INPUT LOCATION ON THE FLOOR COVERING AND TRANSMITTED THROUGHOUT SO THAT IT CAN BE SUPPLIED THROUGH A COUPLER THAT ENGAGES THE FLOOR COVERING WHICH IS CONNECTED TO A RECEIVING UNIT PLACED ANYWHERE ON ITS SURFACE. IN ONE EMBODIMENT, THE ENERGY IS CARRIED THROUGHOUT THE FLOOR COVERING BY A GRID SYSTEM OF A PREDETERMINED PATTERN. IN ANOTHER EMBODIMENT, THE FLOOR COVERING COMPRISES A SERIES OF LAMINATIONS INCLUDING AN UPPER LAYER OF CONVENTIONAL CARPET-LIKE FABRIC, SPACED APART SUB-LAYERS OF ELECTRICALLY CONDUCTIVE MATERIAL SEPARATED BY A DIELECTRIC LAYER WHICH MAY SERVE AS A PROPAGATION MEDIA FOR ENERGY AT MICROWAVE FREQUENCY. ELECTRICAL POWER TRANSMISSION IS INCREASED IN ANOTHER EMBODIMENT BY SPACED APART WIRES EMBEDDED BETWEEN CERTAIN OF THE LAMINATED MATERIALS.
