Suura - Data Offload for Mobile Network Operators

Suura.com have developed patent-pending technology to silently authenticate 3G subscribers onto existing WiFi networks, without modification to those networks, creating the opportunity for 3G data subscribers to roam, without intervention, onto more cost efficient WiFi networks. Suura also meters the use, so the WiFi provider can be compensated for the offload. Suura brings the promise of low-cost WiFi access through public hotspots. The system is targeted towards users that wish to surf the Web or make VoIP calls while they are roaming. Suura has the ability to seamless authenticate mobile devices through WiFi hotsposts using a single click mechanism and works on all the major mobile platforms.See Video.

An Efficient Technique for Robust Detection of Digital TV Signals

As analog TV transmission shuts down throughout the world, corresponding frequency spectrum is released for the use of not only digital TV but also other services in a more openly regulated environment. Similarly the unoccupied white spaces in the TV spectrum are increasingly being used for a wide range of applications. This requires a more sophisticated approach for spectrum planning and control, to avoid interference with digital TV receivers. This new approach highly benefits from the availability of robust spectrum analysis and monitoring tools that identify the digital TV channels in use and measure the signal quality in those channels. Feature based identification using pilot tones embedded in digital TV signals is not always reliable or easy, as it can be difficult to see the features in a  signal which is distorted by noise and wireless propagation effects. The solution presented here applies advanced signal processing techniques to overcome these problems. It automatically scans digital TV broadcast over the air, employs protected smart techniques to be able to detect both strong and weak digital TV signals, and identifies channels in use as well as the signal type and quality in a very short time. In addition to its robustness and efficiency in signal measurement and monitoring applications, the solution can be used by digital TV tuners for the fast and reliable scanning of available channels.

Scalable Programmable Architecture for Ray-Tracing Applications (SPARTA)

SPARTA consists of a novel, scalable Distributed Shared Memory (DSM) FPGA cluster and a parallel ray-tracing engine that exploits the unique features of the cluster to enable photorealistic rendering of large-scale dynamic scenes at interactive frame-rates. The product will be brought to market in two stages. Initially, the hardware will be marketed as a standalone product and this will be followed closely by the ray-tracing engine. This strategy will allow early access to the market as well as providing an early income stream for the company before the ray-tracing engine is brought to market..See Video.

Reconfigr - Reconfigurable Communication Systems

Researchers at Trinity College Dublin have developed a software radio system for maximum application flexibility and minimal RF hardware. FlexRad is presented as a software radio toolkit and development system for wired and wireless communications products. A FlexRad system can be completely changed in software unlike a conventional transceiver where the application is fixed in hardware or has a limited ability to be changed after deployment. One concrete example of this toolkit being used in the real world: a dynamic spectrum access system was built using FlexRad that automatically detects and avoids interference to maintain a robust communications link at all times. This is a product that is tailored for robust and cost effective wireless links and connectivity. The solution uses clever detection and self-adaptation techniques and otherwise unused frequency spectrum segments or ‘white space’ in the UHF band to achieve blanket coverage and maximum building penetration across a target area.

Text Resources and Visualisation for ELearning Languages (TRAVEL)

Researchers in Trinity have developed a system for the presentation of text which is synchronised with recorded speech as an aid in the learning of languages and literacy. This system provides a student with a visual association between text and audio in a manner that will assist in learning vocabulary, enhance their reading ability and will reinforce correct pronunciation. As the words are heard by the final user they are simultaneously highlighted on a screen. Initially, the system takes an audio recording and its associated text transcript, partitioning the audio recording into discrete words enabling the creation of instantaneous highlighting of text on the screen. This novel aid functions as a support to teaching. This system uses natural human voice of the teacher rather than the standard synthesized voice found on other text audio compositors. In this way intonation and linguistic emphases are maintained.Non-Confidential Flyer.

FlexiRad

Researchers at Trinity College Dublin have developed software which, with the addition of an extraneous antenna, will perform all the functions of traditional radio without any additional hardware. FlexiRad is presented as a software radio toolkit and development system for communications products. All extant commercially available radio solutions require a certain amount of essential hardware which in this system is replaced by software which can be installed on any computer.
One concrete example of this toolkit being used in the real world: a Cognitive Radio system was built using FlexiRad that automatically searches for free bandwidth, providing an interference free signal at all times. This is possible due to the ‘backhaul’ element of the system which uses combination of otherwise unused frequency spectra in the television band and self adaption technologies to achieve blanket coverage across an area. This is a product that is tailored for cost effective wireless across non-line of sight distances and/or terrain where conventional line of sight links cannot be established. Non-Confidential Flyer.

MeshTV

Internet TV is centralised and non scalable due to large bandwidth requirements based on the sole content transmitter. Researchers in Trinity have developed MeshTV; a peer to peer (P2P) Internet TV broadcasting system. MeshTV works by having the primary transmitter send content to a small number of computers who in turn replicate content to other computers and so on. This distributes bandwidth requirements across all participating computers. The system is comprised of a number of decentralised algorithms for adapting mesh overlay. The overlay adapts so that all peers download media content at approximately the same rate. This system can therefore be used by TV broadcasters to provide high definition live broadcasts over the internet. Non-Confidential Flyer.
