This article shows the development and implementation of a device which is capable of monitoring peripheral oxygen saturation in the blood (SpO2) and heart rate of a person in beats per minute (bpm). This can be achieved by conditioning the signal obtained from the sensor Nellcor DS-100A, including a step of converting the current signal to voltage, a step of noise Altering in the signal and finally...
The popularization of the Web and the advent of new information and communication technologies of mobile devices make possible new aspects for management, interaction and information sharing. In petroliferous area, monitoring systems on mobile devices have been used for process optimization, data monitoring, reporting, alarm generation and identification of failures in real-time on oil wells platforms...
This paper presents the use of Near Field Communication and mobile technologies for the development of ubiquitous games. We describe all the components necessary for the building of ubiquitous games: the MIDlet or program running on the mobile phone with NFC features, the services available in the back-end system in charge of the game control and the tool devoted to real-time surveillance and visualization...
A novel, patented, mechanical rowing force sensor has been simulated, constructed and tested. The sensor was set in a modified oarlock together with electronic processing including a Bluetooth transmitter. A Bluetooth-enabled mobile telephone/ laptop with a Graphical User Interface written in Java was used to display the 2-dimensional force on an oar vs. time. The visual display to a coach of rowing...
Health care systems will integrate new computing paradigms in the coming years. Context awareness computing is a research field which often refers to health care as an interesting and rich area of application. One of the areas for context aware computing is social awareness amongst a group of individuals. Providing individuals with social awareness about other coworkers is very important in order...
Traffic security is one of the most important problems to be improved for our daily environment, especially in Japan. Surveillance systems are effectively used to observe intrusion into dangerous and security area. They are well evaluated to monitor whether people enter such an area or not. A remote surveillance system has been developed, which supports users of mobile phones to facilitate network...
Wireless sensor networks span from military applications into everyday life. Body sensor networks greatly benefit from wireless sensor networks to answer the biofeedback challenges in healthcare applications. In such applications, data is of fundamental importance, it must be reliable and within easy reach. However, most solutions rely on a personal computer to process and display sensor data. In...
Policies form an important part of management activities and are an effective means of implementing self-adaptation in pervasive systems. Many policy- based systems designed to date focus on large-scale networks and distributed systems. Consequently, they are often fragmented, dependent on infrastructure and lacking flexibility and extensibility. This demonstration presents Ponder2, a self-contained,...
A low-cost intelligent mobile phone-based wireless video surveillance solution using moving object recognition technology is proposed in this paper. The proposed solution can be applied not only to various security systems, but also to environmental surveillance. Firstly, the basic principle of moving object detecting is given. Limited by the memory consuming and computing capacity of a mobile phone,...
Distributed software systems are characterized by increasing autonomy. They often have the capability to sense the environment and react to it, discover the presence of other systems and take advantage of their services, adapt and re-configure themselves in accordance with the internal as well as the global state. Testing this kind of systems is challenging, and systematic and automated approaches...
