Back electromotive force is the way the qsi three rail sound system has worked since day I. They had it available in there 3 board systems way before MTH decided to go with proto 1 sounds,which was made by qsi. If mth thinks they invented bemf, qsi was the 1st to use it in 3 rail and I can;t tell you if anyone used it before them or not, but mth did not invent bemf or as far as I know patent it. But if it is true that you can patent 1 mph speed increments, then our patent system needs to be overhauled. |Why don;t the dcc people just use 1.5 or .75 etc speed increments. You can eat me alive for saying this as it is my opinion only that MTH is playing poker here with the threat of sueing over scale increments. Have they actually told anyone the patent number or numbers they are referring to in the letter to DCC companies. This would be very interesting to find out. Anyone out there interested in researching patents????????????????????????dave roxin
