Rover is a system that enables location-based services by tracking user locations. It uses a Rover controller to interact with location services, clients, and content providers. The system architecture includes Rover clients, wireless access points, servers like the location server and media streaming, and a Rover database. It aims to scale to serve large numbers of users across various devices and wireless technologies.

This presentation is elaboration about the history of Navigation System, RADAR, different types of Satellites,Global Positioning System Satellites, Wide Area Augmentation System, aircraft tracking and technology management.
In this technology, light is passed through transmission channel as it is the fastest medium. It overcomes the defect of WI-FI as well. Transmission of data takes place through illumination. Using this, we can connect to several devices under a single LED light.
Eye Movement based Human Computer Interaction TechniqueJobin George
Eye movement-based interaction is one of several areas of current research in human computer interaction in which a new interface style seems to be emerging. In the non-command style, the computer passively monitors the user and responds as appropriate, rather than waiting for the user to issue specific commands. In describing eye movement-based human-computer interaction we can see two distinctions, one is in the nature of the user’s eye movements and the other, in the nature of the responses. In the world created by an eye movement based interface, users could move their eyes to scan the scene, just as they would a real world scene, unaffected by the presence of eye tracking equipment movement, on the eye movement axis. The alternative is to instruct users of the eye movement based interface to move their eyes in particular ways. On the response axis, objects could respond to a user’s eye movements in a natural way that is, the object responds to the user’s looking in the same way real objects do. The alternative is unnatural response, where objects respond in ways not experienced in the real world.
Now a days Eye tracking technology is applied in many fields like automotive defense and medical industries. The fields of advertising, entertainment, packaging and web design have all benefited significantly from studying the visual behavior of the consumer. Every day, as eye tracking is used in creative new ways, the list of applications grows.
Wi-Vi or wireless vision is one of the most modern technologies which use wireless fidelity or Wi-Fi as the core principle. Basically, it deals with tracking and manipulation of Wi-Fi signals.
Wi-Vi is used to image the obstacles or solids behind any wall or obstructions. The most important advantage of this is it is completely wireless and no cables or wires are used. Hence it becomes more suitable for usage in mobile devices and other lightweight technologies. Wireless facility also allows it to use in armed force and other security agencies.
As we know that SOANR and RADAR uses the principle of transmission and reflected waves, the Wi-Vi which uses the same principle can be called as an adaptation of those. But it also posses several differences and simpler apparatus. We will see those modifications on the coming pages of the paper.

Braingate is an electrode chip which can be implemented in the brain. When it is implemented in brain, the electrical signal exchanged by neurons within the brain. Those signals are sent to the brain and it executes body movement. All the signalling process is handled by special software. The signal sends to the computer and then the computer is controlled by patient.
Radisys/Wind River: The Telcom Cloud - Deployment Strategies: SDN/NFV and Vir...Radisys Corporation
Radisys and Wind River present on the evolution to the Telecom Cloud and how cloud technology and network virtualization will provide both big opportunities and challenges for operators. Important details and insights are shared on Network Function Virtualization (NFV), Software Defined Network (SDN) and Virtualization.
Enabling the Deployment of Edge Services with the Open Network Edge Services ...Liz Warner
The Open Network Edge Services Toolkit (OpenNESS) is an open-source software toolkit for the enablement of orchestration and management of edge services on a diverse range of platforms.

Turbocharge the NFV Data Plane in the SDN Era - a Radisys presentationRadisys Corporation
On October 8, 2014, Karl Wale (Director of Product Management) and James Radley (Architect) presented: Turbocharge the NFV Data Plane in the SDN Era. This expert duo discussed the evolution of the network and service provider objectives around the challenges of deploying SDN/NFV solutions. They take you through some application use cases and introduce the new Radisys FlowEngine data plane software technology.
Faced with the dual threats of rising operating costs and declining revenues, network service providers are increasingly turning to network functions virtualization (NFV) to help them keep up with constantly changing market conditions.
In a virtualized Telco environment, service providers can deploy and deliver new network functions, services and capacity on demand—reducing normal rollout time from months and weeks to just hours.
Leveraging the principles of cloud computing, network service providers can deliver a level of responsiveness never before available, easily scaling capacity up or down to meet the evolving needs of their subscribers.
The result is a highly agile system that allows new revenue-generating services to be quickly developed, exhaustively tested and selectively rolled out to targeted groups in a fraction of the time and at a much lower cost than previously thought possible.
In this session, the speaker will present how the solution from Juniper networks look like and how it can be deployed by service provider to improve their agility in delivering services to their customers.
