1990 Quadrature encoder noise filter with fastest, most accurate analog-digital regulation
1989 Design of DEFT-1 tachometer
1989 World’s First look-ahead preemptive start/stop control – Waihi Gold, New Zealand
1988/9 First curved conveyor – 20.5 km overland with longest horizontal curve arc at 5 km – Channar, Australia
1987 Predicted pulley failures (1987-1993) – Kennecott, Bingham Canyon, USA
1987 Quintette, B.C., Canada, Redesign of brake (existing brake proportional control caused runaway). Replaced with very fast acting hydraulic disk brake (70 msec) and pulley re-design (corrected drive pulley design flaw)
1987 Syncrude, Alberta, Canada, Sandy Terrain and -50 degrees C. CDI predicted the shaft failure at the locking device interface. Belt flexure testing and rolling resistance measurement machines were also used in the project.
