THE INTEGRATED UNIT FOR MEMS BASED PRESSURE MEASUREMENT March 2009

The article deals with a custom based integrated measurement unit

(IMU), which serves as processing device for MEMS based pressure

measurement.

 

The IMU consists of the three elementar stages, measurement

stage, processing stage and communication stage. They are

implemented on the one single board.

 

The measurement block has 16-bit resolution with 64 provided

measurement ranges to satisfy appropriate accuracy. The power

supply is 5 V, which allows to measure current with 238 nA step

within 1 mA measurement range.

The communication stage is based upon 12C standard.

THE MOBILE ECG TELEMONITORING SYSTEM BASED ON GPRS AND GPS April 2009

 

This presentation provides a description of a new mobile ECG telemonitoring

system.

 

The portable ECG monitoring terminal in the system consists of GPRS and

GPS module in order to send the ECG signal data through GPRS network with

the position information of the user, and a accelerometer is embedded in the

terminal to sense the sudden posture change of the user, this will enable the

monitoring center in the system give a immediately response to the user who

suffer a suddenly cardiac failure.

IMM-BASED LANE-CHANGE PREDICTION IN HIGHWAYS WITH LOW-COST GPS/INS March 2009

 

The prediction of lane changes has been proven to be useful for collision

avoidance support in road vehicles. This paper proposes an interactive

Multiple model (IMM)-based method for predicting lane changes in highways.

The sensor unit consists of a set of low -cost Global Positioning

System/inertial measurement unit (GPS/IMU) sensors and an odometry captor

for collecting velocity measurements.

 

Extended Kalman filters (EKFs) running in parallel and integrated by an

IMMbased algorithm provide positioning and maneuver predictions to the user.

The maneuver states Change Lane (CL) and Keep Lane (KL) are defined by two

models that describe different dynamics.

 

Different model sets have been studied to meet the needs of the IMM-based

algorithm. Real trials in highway scenarios show the capability of the system to

predict lane changes in straight and curved road stretches with very short

latency times.

DESIGN AND ASSESSMENT OF AN ONLINE PASSENGER INFORMATION SYSTEM FOR INTEGRATED MULTIMODAL TRIP PLANNING June 2009

 

This paper presents the design and evaluation of an online passenger

information system for delivering personalized multimodal trip planning

services through the integration of wireless and Web-based communication

technologies.

 

The goal of the system is to provide real-time travel information throughout

the entire life cycle of an interurban trip. Before the full-scale deployment of

this type of system, it is essential to assess its impact on the involved

stakeholders through a pilot application.

 

The proposed system (ENOSIS) has been implemented and evaluated for

supporting travel decisions in Greece. An evaluation framework for assessing

the impacts of the ENOSIS system is proposed, and the evaluation results of

the ENOSIS pilot application are also reported.

The evaluation results provide significant evidence of the technical and

operational efficiency of the ENOSIS services, while it is shown that the

proposed system is cost effective.
