I've recently patented a mechanism which converts high speed rotary motion to slow speed, high force, ultra-precise linear motion using a single moving part. Details can been seen here: https://www.youtube.com/watch?v=Jz3d58lz7Dk I've recently begun the marketing/licensing process but am having trouble getting any useful feedback. If any of you, my fellow mechanical engineers, would be so kind as to critique the positives and negatives of my invention I'd be very grateful. Thank you . . .
