Jeff Woolf of more than six million randomly placed and sized dots per square inch. MicroMap and Woolf were discussed during a debate on innovation in the House of Commons. During this debate, a MicroMap viewer was handed around for members of parliament to use. Woolf worked with Ron Hickman, inventor of the Black & Decker Workmate and designer of the Lotus Elan car, to some extent, benefiting from his patent experience before the final patent application was lodged. MicroMap was patented in many countries around the world. There is a display on the development of MicroMap in the Science Museum in
Lotus Elan early cars, while 3.55 differentials became more common in later cars (especially the more powerful Sprints) to provide more relaxed cruising on newly built highways. The final drive used four Rotoflex couplings (colloquially called rubber doughnuts) to connect the differential output shafts to the rear hubs. These couplings were widely used at the time for road vehicles (e.g. Hillman Imp, Triumph GT6) and racing (e.g. Ford GT40, Lotus 21), prior to the availability of constant velocity (CV) joints. In the case of the Elan, which had exceptionally supple rear suspension that allowed significant vertical wheel travel, the deformation of the
