The construction of the Ford ELTEC (Electronic Technology) vehicle has offered a unique opportunity to demonstrate the practical advantages of using modern electronics in a family car. Included in the specification is the integrated control of a lean burn engine and a continuously variable transmission from a single microprocessor. A number of novel features are controlled such as ionisation feedback, intake port, variable geometry induction and an electronic throttle.

This paper reviews some of the methods and experience with the DRAM Program, as it has been developed for interactive simulation of realistic mechanical machinery. The Program has been made interactive by increasing solution speed and providing for output of a moving drawing of the mechanism on time shared graphic display terminals. At the same time program generality has been expanded by including effects such as Coulomb friction and impact.

Conclusions based on the airborne experiments with laser radars are summarized in this paper. Details of the equipment and the flight procedures will be displayed during the oral presentation at the conference.
