Collecting information about faults, state of surrounding environment and equipment is crucial in systems that could jeopardize human lives, such as trains. Normally, data are obtained via analog sensors which do not have any interface to allow their integration with software systems. Additionally, acquisition and transport of sensor data could suffer interferences in the train's environment due to...
One of the hot topics of today's world is security. Not only companies spend more and more money in order to protect their valuable assets (physical and digital), regular people also need enhanced forms of security regarding personal sensitive information. Traditional password methods for protection of information are prone to brute force attacks, as computational power increases. The focus has then...
While Bluetooth Low Energy (BLE) is emerging in personal wireless network communication, aimed at applications such as healthcare, fitness and many others, there are still some pitfalls, namely concerning reliability and accuracy for its application in range sensing areas. BLE is designed for ultra low power consumption, ideal for applications requiring episodic or periodic transfer of small amounts...
The miniaturization and cost reduction of sensors is encouraging its wide spreading and application in diverse usage areas. The use of multiple types of sensors can improve the current surveillance systems, by reducing false positives, extending the type of detected events and increasing system's redundancy. Also, geo-location is becoming more precise and available at lower costs, thus enabling its...
Surveillance systems are evolving and analog cameras give way to IP cameras, wireless sensors are used in home surveillance, remote mobile phones access to video surveillance is current practice, but the concept itself, of “surveillance systems”, has not evolved accordingly. Control rooms are still the heart of operations, where several security guards spread their attention over an array of monitors,...
Surveillance systems are in constant development and its dependence of humans although dwindling, it is still significant. On the other hand a constant evolution and adaptation of robots to perform tasks traditionally performed by humans it is also been witnessed. Using the advantage of these fields an architecture and a protocol to facilitate the integration of an autonomous robot as active agent...
