Abstract:
1. An inductively coupled sequential power transmission system comprising: a rechargeable central battery adapted for portable wearing by a soldier, a garment used in a soldier system, said garment having pockets and having an electrically conductive first electrical network mounted therein wherein said first electrical network has an infeed end mountable to, in electrical communication with, said central battery, and outfeed nodes, a first set of inductive primary coils mounted to said pockets and electrically connected to said outfeed nodes, a pocket-mountable independent battery powered accessory mountable into said pockets and having an inductively coupled sequential power transmission sub-system mounted thereon and a rechargeable secondary battery charged by said sub-system, wherein said sub-system includes a second electrical network having at least one inductive secondary conduit extending from an infeed end to an outfeed end, wherein at least one inductive secondary coil having secondary ferrite chosen from a backing, a core, is mounted at said infeed end and said secondary battery is mounted at said outfeed end of said second electrical network in electrical communication therewith, and wherein each primary coil of said primary inductive coils is chosen from: (a) a rigid, low profile substantially planar coil having cooperating primary ferrite chosen from a housing, a core, and wherein said each primary coil is mounted flush to said pockets, wherein said low profile coil does not interfere with access of said accessory into said pockets, (b) a cylindrical coil having a primary ferrite chosen from a housing, a core, and wherein each said secondary coil is internal to a corresponding said accessory, and said each primary coil protrudes into said corresponding accessory when said corresponding accessory is mounted in said pocket, and wherein said each primary coil is no larger than said accessory so that when said each primary coil is mounted to a said pocket said each primary coil is no wider or taller than a corresponding surface of said accessory adjacent said each primary coil so as not adversely affect garment flexibility when said accessory is mounted in said each pocket, and wherein said each pocket is adapted to mechanically align in a pre-determined fixed alignment said accessory in fixed relation relative to said each primary coil so as to mount said inductive secondary coil on said accessory proximal adjacent to and flush with, and so as to be substantially aligned over said each primary coil, wherein said ferrites direct the magnetic flow between said each primary coil and said secondary coil to minimize flux leakage and optimize magnetic coupling efficiency, whereby when said primary and secondary coils are in said close proximity and aligned they are substantially maximally magnetically coupled.
