I wasn't trying to put an end to anything. As far as I can tell looking at the pics the artwork was barrowed and rotated. However, the algorithems and circuits are on the inside. If you don't have a label and your switching components on a circuitboard you better label them somehow. Because they will be the same shape and size. If I were going to alter a circuit board to do a better job for me I would take the circuit board and make changes on it. I would not start from scratch. Now if you are producing something to patent and sell the product better have it's unique production so that patent infringement cannot be charged. However, durring the early stages I would probably start with someone elses product. Ernie
