Patents involving antenna and aerials, mainly for transmitting...

NOTE:
This is merely research.  I don't have the freedom or the money right now, where I live, to experiment, except for the simplest, cheapest types of components.
And, I live with veterans, some of whom are former addicts and alcoholics---which adds stress to my daily routine.


#6,750,752
Fig. 2 is the most likely relevant to Overunity.com
3 toroids in series, the last one in line has only one turn in the coil.




#5,986,617
Fig. 4, as a transformer, can be used to step up voltage.




#5,457,469
Simple TV aerial system that can be scaled way up in size.




#5,200,718
This is something.  Wonder what a Joule Thief would do with it?

I would do more if I had more privacy in a better location.





#4,028,704
The toroid at the base of this whip antenna is the active component.




#3,961,332
This might be used alone or have additional lengths of wire added to the spiral ends.




#3,110,030
These log periodic aerials are fine if you have the room to build them in sufficient size.  They're inherently variable in the length of individual segments and they may or may not cross over as a loop, one or more times.




#2,650,303
This might be sort of a balun combined with a loop antenna for a radio.




#2,484,028
Fig. 3 is the main interest, but Fig. 4 is a bridge circuit with 2 coils and 2 capacitors opposite them.





#2,218,083
Fig. 1 without the electronics is an actual antenna input/tuning system.  A lengthy coax cable may add even more to the output.

Here's one you missed:

Our initial tests back in 2004 using this design captured over 90 Volts with a 2 foot antenna in the city of Pittsburgh.

You can build it and use it, but not sell it...the patent is active and is currently being used by Powercast, for their wireless power products.

Here's the GOOGLE patent search address:

http://www.google.com/patents?id=B_d3AAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q=&f=false

(Free Patents Online isn't really, ultimately 'free'.  You can get the Claims, but if you want a whole patent, eventually you'll have to sign up and pay for the service.  That's why I don't use it for searches.)

You're right.  It's a simple design, as shown in the patent, but it's dependant on local municipal power for efficiency.
Suppose you took it outside, away from the power lines available in Pittsburgh?  How much bigger would the unit need to be to get the same voltage?

It doesn't perform well if its away from large concentrations of RF energy, like rural farms, little towns, etc.
You can use this device to capture stray RF from commercial broadcast stations- TV, radio, cell, microwave, radar and the like. It doesn't capture energy from the power-lines.
For example, a resonant 1/2 wave dipole antenna for 60 Hz would be over 14,000 miles long.

Powercast is using this type of circuit to power remote sensors and do remote charging of batteries and remotely charge large capacitors.

Funny, I invented it to 'clean-up' the stray RF that is polluting our major cities and re-cycle it into powering useful things, like clocks, smoke detectors, battery charges and other low power consuming devices.
But after Powercast bought my patent, they just added to the RF problem by coupling my power supply circuit with a special type of transmitter so they can power remote things anywhere.

BTW, the US patent office search engine works great & its free:

That was the focus of my question.  I imagine the aerial needs to be substantially longer?

That concept bothered be for a few minutes.  Now that I think about it, if the emanated signal(s) are being grounded by this device, they're effectively dealt with in the way you envisioned for your patent, right?

I'm trying to grasp the concept as I write.
If a dishonest person wraps a coiled wire around a non-energized (!!!) power line, to steal power, it'll conduct at 60 Hz.  If the same thing was done with a fluorescent tube near a Tesla coil, is the Tesla coil being loaded down by that resonant conduction?  Would the same thing happen to power supplies using your patented device?  That is, to be more heavily loaded by the resonant conduction?

I agree.  There distributing the problem around the landscape.

I, and the public library, have been having problems accessing the site and printing off pages.  The librarian himself hinted that his opinion was that USPTO was clamping down of access as a deliberate restriction.  My more conciliatory explanation is that they might do it for budgetary reasons to cut costs.  There's always politics of all kinds to consider, as well.
