ABSTRACTIncreasing numbers of deep draft vessels and fixed and semifixed subsurface structures represent a growing hazard towards the world's Fleets of military and commercial submersibles. In this paper, the hazard is defined, and the Submarine's ability to avoid is investigated. The Submarine is found to be lacking.

Microwave anti-collision system
2011 IEEE 17th International Symposium for Design and Technology in Electronic Packaging (SIITME), 2011The anti-collision system for vehicles, proposed through this paper, includes a speed sensor to measure the speed of the vehicle, a space sensor to measure the distance between the vehicle and a detected object, a computer to calculate a danger-of-collision distance to the object, an alarm actuated by the computer when the sensed distance to the object

The problem of collision-avoidance at sea by means of radar is constantly under discussion in maritime circles within the U.S.S.R. This paper, and that of Captain Bukhanovski (Journal, 20, 247,), describe one direction of research that has been actively pursued in the Soviet Union.The device described was developed by the Central Scientific Research ...

This contribution describes the basic concept and practical evaluation of a driver assistance system, which early detects dangerous overtaking maneuvers on two-lane rural roads and helps to prevent accidents. A fusion of video and radar data combines a high-precision detection of far objects with accurate lateral position and velocity estimates for ...

In the discussion on the theory and practice of collision avoidance, two areas have been particularly liable to dispute, namely the rules for direction of manoeuvre and for responsibility for manoeuvre. Where two craft meet, some propose a rule of manoeuvre direction fixed by relative bearing, others a flexible rule designed to increase initial miss ...

A novel anti-collision scheme for RFID systems
2014 IEEE World Forum on Internet of Things (WF-IoT), 2014Because of low cost and easy-to-use feature for RFID cards, more and more operators adopt RFID technique to identify their goods. When there are many goods with RFID cards put together, collision happens when trying to identify each good from the other. Some tree-based schemes are proposed to solve this problem.

IDMA Based Anti-collision in RFID Networks
International Journal of Wireless Information Networks, 2013Even though object identification is its main objective, it is generally accepted that there are some technological challenges that should be addressed in order to exploit the full potential of RFID (Radio frequency identification). The anti-collision problem is one of them. Despite the different proposed methods, it still needs further study on how to

An Improved Anti-collision Algorithm in RFID System
2009 Ninth International Conference on Hybrid Intelligent Systems, 2009Based on the analysis of the EPC Binary-tree algorithm, an improved algorithm is proposed. Compared with EPC Binary-tree algorithm the proposed algorithm will get more efficiency, higher utilization, and much more precision with fewer slots.

ICT Anti Collision Radar for Road Traffic
2007 IEEE 66th Vehicular Technology Conference, 2007The ICT radar is an information-communication technology system for early warning and collision avoidance on roads and motorways. This radar uses special sensor network, which - spanned over the moving vehicles and road obstacles - transmits automatically warning signals to the back of column and enables distant drivers to stop in time or to do such ...

Optimized anti-collision techniques in RFID systems
2007 9th IFIP International Conference on Mobile Wireless Communications Networks, 2007RFID systems are widely used in many diverse applications at present. A development of anti-collision technique is one of the most important issues for tag identification. In this paper we present an analysis for computing the optimal parameter for tag-collision resolution problem based on the EPCglobal RFID protocol [6].
