UWB Radar system for road anti-collision application

2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications, 2008
The inter-vehicles communication is becoming increasingly mandatory to improve the road safety and to allow a better transport management. The concept behind an intelligent vehicle consists in equipping this vehicle with an optimum number of sensors, in order to perceive the environment surrounding it and to ensure an automatic guidance control and the

II.—Simulation of Anti-collision Problems

Journal of Navigation, 1973
The object of this paper is to describe how anticollision simulation is employed at H.M.S. Dryad, the Royal Navy School of Navigation. The methods described are those used in the Navy but this paper has no specific military slant, nor do the anti-collision problems studied at Dryad spring exclusively from the naval environment.

Anti-collision methods for chipless RFID systems

2015 Asia-Pacific Microwave Conference (APMC), 2015
Radio Frequency Identification enables automatic identification of objects with least human involvement. Chipless RFID is the low-cost alternative of conventional chip based system. In many application multiple tags collide with each other making the reading and identification challenging for the reader.

Dynamic Anti-Collision System for Hydraulic Cranes

IFAC Proceedings Volumes, 2011
Abstract The need for dynamic anti-collision systems is rapidly increasing. The future stopping positions of a crane and its neighbor cranes are predicted, which allows to stop the cranes on time to avoid collision. The brake path calculation includes reaction times and is realized via kinematical transformer.

Anti-collision Manœuvres when using Radar

Journal of Navigation, 1954
When using radar in thick weather as an anti-collision warning device it is necessary, when planning any manœuvre, to consider the effect of the proposed alteration of own vessel's course and/or speed on the PPI presentation of the target vessel's radar, should she be using it.

Watchdog: An Anti-Collision Wellhead Monitoring System

Proceedings of International Arctic Technology Conference, 1991
ABSTRACT BP Exploration undertook the development of a new rig safety system to provide an increased level of protection against sub-surface well collisions. The Watchdog system is an acoustic wellhead monitoring system designed to warn the driller when a collision with an existing well is imminent. Monitors are placed on the wellhead of
