Abstract Antilock braking systems (ABS) are inherently limited by the static coefficient of friction (µ) between a vehicle’s tires and the road surface. This paper explores a unique active safety concept, Integrated Coefficient Enhancement (ICE), which works to improve ABS well beyond their present limits. The ICE concept was developed using a basic physics principle: to change µ between two surfaces, at least one of the surfaces must be altered in some way. By quickly deploying a specially designed tractive medium (TM) to aid in directional stability and braking, hazardous situations can be greatly mitigated. This paper describes the features and testing results of this TM and its aerodynamic-mechanical-electronic deployment apparatus. Under all slippery road conditions tested, the developed TM mitigated skidding, with improvements that ranged from 20% to several hundred percent, depending on conditions and deployment rates.

The purpose of this information report is to present the factors that affect the design and development of aircraft jet blast windshield rain removal systems. Rain removal system design will generally be unique to specific aircraft. Design of these systems typically requires a preliminary design for the system based on available empirical data to be followed with a laboratory development program and a flight test validation program. Published windshield rain removal performance test data is available only for limited windshield configurations.

This paper discusses the challenges and opportunities in the truck industry and especially the efforts of DAF Trucks N.V. in improving traffic safety and the environmental impact related to trucks. Proposals regarding legislation, new technologies and the approach to be followed, in order to reach the desired goals, are presented. Various new technologies investigated in DAF Trucks N.V., like platooning are explained, to show the open perspective of the company towards finding solutions and the commitment to invest in this effort. As a significant message this paper wants to convey, is the need for all the stakeholders to work together in an joint effort to achieve the best possible results.

Highly diversified market needs, non-harmonized regulations and new technological trends in future construction machinery industry will challenge OEMs in defining their appropriate development strategies. Main trends like “efficiency”, “safety/security” as well as “connectivity” are considered as important driving forces in future product - and customer service - developments. Some examples are given for the above mentioned trends. Chances and related risks of such development trends are considered as well.

Many autonomous driving plans call for deploying a handful of solid state Lidar sensors on each vehicle, but the Lidar modules used on today’s prototype vehicles are all mechanical systems with moving parts. That’s prompted huge interest in solid-state Lidar, with OEMs and suppliers racing to invest in non-mechanical technologies.

This test method provides stakeholders (runway deicing chemical manufacturers, users, regulators, and airport authorities) with a relative ice penetration capacity of runway deicing/anti-icing chemicals, by measuring the ice penetration as a function of time. Such runway deicing/anti-icing chemicals are often also used on taxiways and other paved areas. This test method does not quantitatively measure the theoretical or extended time of ice penetration capability of ready-to-use runway deicing/anti-icing chemicals in liquid or solid form.
