Get thyself to a patent attorney, ASAP! There is no such thing as a "poor man's copyright" for a patent. That only works for writings, not for inventions. You patent ideas, and copyright words. Patenting an invention and copyrighting a literary work are entirely different. To get a patent, you need an attorney to file the documents with the US Patent and Trademark Office. If you take your idea to someone else, and they use it, you will have to sue them in an expensive, low-probability lawsuit. The more you describe this thing in public, the less patentable the idea becomes.

Don't write another word about this and go get a consultation with a patent attorney who can tell you what to do next, and if the idea can be patented. An initial consultation is usually free. Take advantage of it, you will be glad you did!
