20130226512 | MAGNETO-INDUCTIVE POSITIONING USING A ROTATING MAGNETIC FIELD - A method and system for locating the position of a source that emits a rotating magnetic field. Three or more receivers are deployed or positioned in known position relative to each other, which may be along a common axis in some cases. Phase differences between the magnetic fields measured by the receivers are detected. The phase shifts are used to determine the location of the source. With three receivers, a range and bearing angle relative to a middle receiver may be determined. With five or more receivers, a range and two bearing angles may be determined, thereby providing a three-dimensional position. | 08-29-2013 |

20130072117 | DECOUPLED MULTI-LOOP WIDEBAND ANTENNAS FOR MAGNETIC COMMUNICATION - An antenna for magnetic communications and magnetic communications devices incorporating the antenna. The antenna includes two or more loops physically overlapping, wherein each loop is configured to be connected to one or more driving circuits, wherein the overlapping loops are symmetrically arranged around and overlap an antenna central point, each loop having a center point, wherein the center point of each loop is spaced apart by a distance from the center point of each adjacent loop, and wherein a distance of the loops from each other and from the antenna central point is selected to realize a local minimal mutual coupling | 03-21-2013 |
