Abstract

A system for transmission of at least power using inductive wireless coupling includes an environmentally sealed dongle and a mounting component which releasably mates with the dongle. The dongle is sized for use with one hand, and may be coupled by an umbilical to either a garment of the user or to a vehicle structure for example a seat, in which case the mounting component is coupled to the vehicle structure or to the garment respectively. The dongle and the mounting component include first and second inductive coils respectively and corresponding ferrite cores. The coils are positioned within the dongle and mounting component so that they are aligned for their inductive coupling when the dongle and mounting component are mated. The positioning and alignment of the coils provides a substantially closed magnetic path between the coils. The mounting component may be a receptacle.

Claims

1. A system for the transmission of at least power using inductive wireless coupling comprising:

a dongle, having a housing which is environmentally sealed,

a mounting component configured to selectively releasably mate with said dongle,

wherein said dongle is sized to substantially fit in a palm of a user,

wherein one of said dongle, said mounting component is adapted for coupling to one of a garment, a structure of a vehicle,

and wherein the other of said dongle, said mounting component is adapted for coupling to the other of the garment, the structure of the vehicle,

and wherein said adaption for coupling to the garment, the structure of the vehicle includes an umbilical having a length of substantially in the ranges of 0-30 cm, 0-100 cm respectively,

and wherein said dongle and said mounting component contain first and second inductive coils and corresponding ferrite cores respectively, said first and second coils configured to be aligned for said inductive coupling when said dongle and said mounting component are said mated so as to provide a substantially closed magnetic path between said first and second coils for at least transfer of power between said first and second coils.

2. The system of claim 1 where said umbilical is mounted at a first end thereof to said dongle.

3. The system of claim 1 wherein said umbilical is mounted at a first end thereof to said mounting component.

4. The system of claim 2 wherein an opposite second end of said umbilical is adapted to be mounted to the garment.

5. The system of claim 2 wherein an opposite second end of said umbilical is adapted to be mounted to the structure of the vehicle.

6. The system of claim 3 where an opposite second end of said umbilical is adapted to be mounted to the garment.

7. The system of claim 3 wherein an opposite second end of said umbilical is adapted to be mounted to the structure of the vehicle.

8. The system of claim 1 wherein a housing of said mounting component is chosen from at least one of the group comprising:

a hollow receiver, a hollow receptacle, a housing having planar coupling surface for planar surface-to-planar surface inductive coupling, a housing having linear alignment mechanism, a housing having hollow receiver and internal linear alignment mechanism, a housing having threaded coupling, a housing having a pull-away coupling, a housing having a pull-away alignment mechanism, a housing having releasable fasteners, a housing having releasable fasteners on a planar surface thereof, a housing having a resilient break-away coupling.

9. The system of claim 8 wherein a housing of said dongle is chosen, correspondingly so as to couple with said mounting component, from at least one of the group comprising:

a housing which includes a cube, a housing which includes a cylinder, a housing which includes a cuboid, a housing which is at least partly conical, a housing which is at least partly frusto-conical, a housing which includes a spheroid, a housing which includes a prism, a housing which includes a poly-hedron, a housing which includes a parabaloid, a housing which includes an ellipsoid.

10. The system of claim 1 wherein said coils have a low direct current resistance.

11. The system of claim 1 wherein said mounting component is a receptacle, and wherein said dongle mates in said receptacle, and wherein said receptacle includes a drain, whereby said receptacle is self-draining of fluids.

12. The system of claim 11 wherein said drain includes at least one aperture for clearing solids therethrough.

13. The system of claim 1 wherein said mounting component is a shielded receptacle, and wherein said dongle mates in said receptacle, and wherein said coils are adapted for inductive transmission of data.
