Leg ulcer: conservative treatment.

During 16 years 202 patients with leg ulcer have been studied prospectively. Whenever possible, cure has been obtained in ambulatory, which was the main objective. Surgery was preferentially made after the cure of the ulcer. From the 202 patients, 166 have made a prolonged follow-up. Cure in ambulatory has been obtained in 91% of the patients. We stress the importance of the direct control of all the treatment ...

A flexible framework for data exchange and presentation between wireless sensor...

This paper presents the framework of an interface between wireless sensor networks and personal devices like PDAs, cellular phones and laptops. It possesses a flexible architecture that can be adapted easily to display any kind of data received from the network sensors using content description. The most relevant properties of this system are: portability (it can be used on any device with a standard browser), ...

Distributed sensing and actuation over bluetooth for unmanned air vehicles

A short range wireless network platform, based on Bluetooth technology and on a Round Robin scheduling is presented. The objective is to build an application independent platform, to support a distributed sensing and actuation control system, which will be used in an Unmanned Aerial Vehicle (UAV). This platform provides the advantages of wireless communications while assuring low weight, small energy consumptio...

This paper reports and describes the diverse stages concerning the development of an unmanned aerial vehicle (UAV) named “Aeronave Inteligente com Visão Artificial”, better known by its acronym as AIVA. The design and development of the first aerial platform, the onboard ommunications, the instrumentation system, the bidirectional communications platform to/from ground station, the flight control system, the na...

A bluetooth-based wireless distributed data acquisition and control system

This paper presents an application independent embedded platform for a wireless distributed data acquisition and control system, and describes its application in the scenario of controlling the information processing and communications between sensors and actuators onboard of an autonomous flying robot, in a “fly-by-wireless” approach. The system, which was designed and implemented, comprises a set of nodes com...
