2 ABSTRACT A patient tracking system (PTS) is a potential method for tracking the location of patients throughout a hospital. One such system is described that implements RFID technology. This system will allow for increased efficiency within the hospital workflow, improved space allocation, and faster treatment for emergency patients. The PTS described employs active RFID tags, readers, and fi...

Title of Dissertation: EMBEDDED SYSTEM FOR CONSTRUCTION MATERIAL TRACKING USING COMBINATION OF RADIO FREQUENCY AND ULTRASOUND SIGNAL Won Suk Jang, Doctor of Philosophy, 2007 Dissertation Directed by: Professor, Mirosław J. Skibniewski Department of Civil and Environmental Engineering This study created a framework for integrating the latest innovations in wireless sensor network that automate t...

In the Dynamo project at UBC, we have developed an extensible facility for experimental mobile robotics. It currently consists of nine radio-controlled mobile robots, two CCD colour video cameras, a video transmitter and tuner, radio controllers, Datacube image processing hardware, and a network of transputers. Software for tracking, control, and simulation has also been developed. Ongoing proj...

RFID (Radio Frequency Identification) is a technology that uses radio frequency signals for purposes of identification and tracking of objects, humans or animals. In passive RFID systems, where tags reuse the energy radiated by the reader, coordination capabilities can be considerably limited [29]. This issue leads to conflicts or collisions between the transmissions of the different elements o...

A software-defined radio consists of a programmable communication system where functional changes can be made by merely updating software. In this paper, a software-defined radio 4-QAM (Quadrature Amplitude Modulation) modem system is implemented in LabVIEW. LabVIEW is a widely used graphical programming environment which allows designing systems in an intuitive block-based manner in shorter ti...

This paper reports on the final results of the ESTER 2 evaluation campaign held from 2007 to April 2009. The aim of this campaign was to evaluate automatic radio broadcasts rich transcription systems for the French language. The evaluation tasks were divided into three main categories: audio event detection and tracking (e.g., speech vs. music, speaker tracking), orthographic transcription, and...

This paper will describe the Energetics Satellite Locating Service (ESLS) which is a unique, patented, proprietary satellite based geolocation system. This system called SAT/TRAC for Satellite Tracking, Ranging and Communications may be used to quickly determine the present location within 50 feet of any person, vehicle or object that is equipped with a ESLS low power transmitter. This technolo...

We present our tracking system for the 1998 Topic Detection and Tracking project (TDT-2). This project addresses multiple sources of information in the form of both text and speech from newswire, radio and television news broadcast programs. Our tracking system is probability based and we successfully solve the problem of score normalization across topics with a simple but e ective solution. Te...

Use RFID to efficiently track vehicles going. Mated, efficient monitoring system that allows for accurate vehicle. STS built software based on Aliens API, so the.RFID BASED VEHICLE TRACKING SYSTEM. Operating a managed, busy parking lot can pose significant challenges, especially to a government organization.Abstract: Purpose: Numerous studies suggest that Radio Frequency Identification RFID. 20...

In the presented paper, the principle of frequency domain channel estimation for wireless OFDM systems will be shown. A well known noise reduction technique will be adapted to HIPERLAN/2 and IEEE802.11a standards, and its positive effects will be demonstrated by simulation results. Channel tracking has not been considered by the WLAN standards named above, although it is well known that time-va...
