Contributions to the Danish project SPOPOS
Alexandre Alapetite personal page 2006-2009

Introduction

SPOPOS is a Danish project providing services based on the location of passengers in airports, which was active from 2006 to 2009 (www.spopos.dk, Sporingsteknologiske Person og Operatør Services).

During this project, I was employed at Risø (2006-06 until 2006-12), then at ITU, then at DTU again (2007-08 until 2009-06, Risø being merged under DTU).

Project partners:

• IT University of Copenhagen :: Innovative Communication (Project leader: John Paulin Hansen)
• Risø National Laboratory (later merged with DTU) :: Systems Analysis Department :: Safety, Reliability and Human Factors
• DTU :: Electrical Engineering
• Copenhagen Airports
• Lyngsoe Systems (RFID technology)
• BLIP Systems (Bluetooth technology)
• The Alexandra Institute
• Travelmarket

Open Source software

TinyHTTP2SMS: SMS gateway

During the project, I also developed the TinyHTTP2SMS software for providing a light SMS gateway platform, able to listen to HTTP requests and to use a telephone connected by Bluetooth / COM to automatically send SMS.

It uses the Hayes AT protocol. It supports PDU mode, flash SMS (not aimed to be saved or answered by the recipient), ping SMS (not seen by the recipient), SMS delivery reports, and SMS validity periods.

The software was successfully used with telephones such as Sony Ericsson W880i and K750.

• Download TinyHTTP2SMS (ZIP 70KB)

Usage:
http://example.net:80/tinyhttp2sms/?action=SendSMS&telephoneNumber=%2B4561000000&message=Hello%20World!&validityPeriod=60&requestReport=1&flash=1
http://example.net:80/tinyhttp2sms/?action=DeliveredSMS&telephoneNumber=%2B4561000000&messageReference=12
http://example.net:80/tinyhttp2sms/?action=SendSMS&telephoneNumber=%2B4561000000&validityPeriod=5&requestReport=1&ping=1

SPOPOS SVG map API

And here is my open source JavaScript library to draw some information on an SVG map.
