Bob, we`ve experimented with such a principle, just four little pieces of metal inserted into the holes aroud the inner periphery and coresponding coils at outside periphery. Olny thing was that it was too pricy to manufacture in small amounts as work involved with custom coils is quite time consuming not to mention the lifespan on leaf springs is somewhat limited.

Regs,

Daniel,

If PS has the patent on all the motions-- how is Redrock in additino to almost 35mm adapter company get away with selling anything?

Just wondering-- I'm not sure you can patent the motions.. you can probably patant a design with technical drawings. If I suddenly wanted to patent "using hydrogen as a combustible to propel"-- I couldn't.

Can you please explain?

Example:

here you can find the patent as pdf file. Search for that number or use the link and click on "Video-camera unit and adapter for a video-camera unit" and look on the 5th page from the patent there you will see the motions patented.
