Golem Explanation

 

 

This page is for in-house use of Dyop® Vision Associates LLC.  Rather than add to the detritus of downloaded, I realized that if I obscurely posted them on this page, I could make current versions of the documents available as a URL link.  The concept is “hide in plain sight” in that if you don’t know what to look for, you are unlikely to find it.  The Golem page is also what I used to provide access to the prototype Dyop® files before the patent was published.
