A novel anti-collision protocol for RFID systems

2007 IEEE Workshop on Automatic Identification Advanced Technologies, 2007
A new anti-collision protocol for radio identification systems has been invented. This anti-collision protocol is called the Aloha PN bit transmission protocol. A transponder generates a pseudo-random number (PN), and transmits a signal to an interrogator with a delay or a slot corresponding to the PN bit value.

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

An efficient tag anti-collision protocol for RFID systems

2012 IEEE 2nd International Conference on Cloud Computing and Intelligence Systems, 2012
In low-cost RFID systems, efficient anti-collision protocol of passive tags is very desirable for fast identification. In this paper, we propose a new anti-collision protocol: assigned tree slotted aloha anti-collision protocol. The key technology is to assign prefixes to each frame and slot respectively such that tags can match the frame recognition ...

Dinade System as an Anti-Collision Device

SAE Technical Paper Series, 1968
<div class="htmlview paragraph">Increasing air traffic has produced an increase in midair collisions. This paper describes the airborne collision avoidance system (CAS), which is intended for use by large aircraft. It also describes the Dinade CAS, intended to be installed in small aircraft.</div> <div class="htmlview paragraph">In ...

A Fast Algorithm for Anti-Collision in RFID System

Advanced Materials Research, 2013
This paper proposes a fast query tree-based (FQT) algorithm for anti-collision in RFID system. Tags to be identified would be grouped by a reader randomly at beginning, and the reader identifies a group of tags and records the quantity of tags. Then reckons the number of all tags and carries out optimized group again.

Neural anti-collision system for Autonomous Surface Vehicle

Neurocomputing, 2015
Autonomous Surface Vehicles (ASV) are robots destined for the operation at water basins like lakes, canals, harbors and even open sea. They are used for different purposes, e.g. for patrol tasks, as scouts, or as a support for Navy ships. One of the main tasks of ASV is to move along a fixed path to a destination point.

An Improved Anti-collision Algorithm for ISO15693 RFID Systems

2012
The Radio Frequency Identification (RFID) is an important technology of the Internet of Things. Along with the rapid growth of the RFID technology, security issues have acquired much attention recently. However, most of the RFID security works focus on fake identity or information leaking problems.

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.

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
