Abstract

A novel system for easily aligning a ground mounted power supplying electromagnetic inductor to a vehicle mounted power absorbing electromagnetic inductor is presented. The power supply inductor is preferably mounted within a parking block or a speed bump. The power absorbing inductor is mounted in a vehicle, preferably between the front tire and the front bumper. When the vehicle'"'"'s front tires touch the parking block or the speed bump, the two electromagnetic inductors are aligned sufficiently to transfer power efficiently.

Claims

1. A method for aligning a stationary oscillating magnetic field power source and a vehicle-mounted oscillating magnetic field power absorber, comprising:

(a) providing a stationary magnetic inductor means,

(b) providing a vehicle-mounted magnetic inductor means,

(c) providing a physical contact barrier means that hinders the longitudinal motion of the vehicle,

(d) defining a point of barrier contact on the vehicle,

(e) defining a point of vehicle contact on the barrier,

(f) placing said vehicle-mounted magnetic inductor means within the vehicle a first longitudinal distance away from said point of barrier contact, and

(g) placing said stationary magnetic inductor means outside of the vehicle a second longitudinal distance away from the said point of vehicle contact on the barrier, said second longitudinal distance being substantially similar to said first longitudinal distance,

whereby a substantial longitudinal alignment between said stationary magnetic inductor means and said vehicle-mounted magnetic inductor means is achieved when the vehicle touches said barrier means, and electromagnetic energy can be transferred from said stationary magnetic inductor means to said vehicle-mounted magnetic inductor means.

2. The method of claim 1 wherein said physical contact barrier means is selected from the group consisting of a wall means, a parking block means, and a speed bump means.

3. The method of claim 1 wherein said stationary magnetic inductor means is enclosed within said physical contact barrier means.

4. The method of claim 3 wherein said magnetic inductor means is slidably mounted within said physical contact barrier means.

5. A system for transferring electrical energy from a stationary alternating current source to a stationary road-vehicle, comprising:

(a) a stationary magnetic inductor means,

(b) electrical wire means connecting said stationary alternating current source and said stationary magnetic inductor means,

(c) a vehicle-mounted magnetic inductor means,

(d) electrical wire means connecting said vehicle-mounted magnetic inductor means to the other electrical apparatus of the road-vehicle,

(e) a stationary physical contact barrier means that hinders normal longitudinal motion of the road-vehicle,

(f) a point of barrier contact being defined on the vehicle,

(g) a point of vehicle contact being defined on the barrier,

(h) said vehicle-mounted magnetic inductor means being mounted a first longitudinal distance away from said point of barrier contact on the vehicle,

(h) said stationary magnetic inductor means being mounted said a second longitudinal distance away from said point of vehicle contact on the barrier means, said second longitudinal distance being substantially similar to said first longitudinal distance,

whereby a substantial longitudinal alignment between said stationary magnetic inductor means and said vehicle-mounted magnetic inductor means is achieved when the vehicle touches the barrier in normal longitudinal motion, and electrical energy can be transferred from said stationary source to the vehicle in form of oscillating magnetic field.

6. The system of claim 5, further including an actuator means for said vehicle-mounted magnetic inductor means, whereby the magnetic inductor can be raised or lowered as desired.

7. The system of claim 5, wherein said stationary magnetic inductor means is enclosed within said stationary physical contact barrier means.

8. The system of claim 5, wherein said stationary physical contact barrier means is selected from the group consisting of wall means, speed bump means, and parking block means.

9. The system of claim 8, wherein said stationary magnetic inductor means is enclosed within said stationary physical contact barrier means.

10. The system of claim 9, wherein said stationary magnetic inductor means is laterally slidably mounted.

11. The system of claim 5, wherein said stationary magnetic inductor means is laterally slidably mounted.
