Try to imagine a “world littered with trillions” of wireless sensors. Now try to imagine the problems getting even a few thousand of them to work together in any kind of intelligible way so you can know if that interstate bridge is near collapse or the natural gas pipe behind a housing development has a crack in it or how dropping your AC temperature by 3 degrees during peak demand will clobber your electric bill. Those are the problems that a new research project at Carnegie Mellon University (CMU) is going to explore. It has, as most such government-industry-academia joint efforts do, the cumbersome name of Pennsylvania Smart Infrastructure Incubator (PSII). The basic idea: Bring together some smart people, give them state of the art facilities and communications, and ask them to wrestle with how to build and run really big sensor networks that can deliver useable information.
L'université de Darmouth propose un logiciel qui s'aide des données captées par d'autres utilisateurs à proximité pour affiner celles, parfois incomplètes, enregistrées par l'utilisateur. Accéléromètre, GPS, microphones... ces capteurs embarqués dans les téléphones fournissent à l'appareil des données indispensables au fonctionnement d'applications telles que la géolocalisation, la reconnaissance faciale, ou l'authentification vocale. Seulement, la qualité de détection de ces capteurs est parfois affectée par différents facteurs. Comme par exemple la situation inappropriée d'un téléphone - placé dans la poche de l'utilisateur, dans son sac à main - pour le recueil de données.
Darwin rend les capteurs de téléphones plus intelligents
Industries everywhere are finding ways to save not only on energy and its costs, but through the use of wireless networks and in numerous other ways too. According to Oak Ridge National Laboratories, through the use of wireless sensor networks, savings on energy for motors used in industrial processes could improve efficiency by 20%, resulting in significant cost savings. Wayne Manges said, "With electric motor-driven systems accounting for nearly one-fourth of all electricity consumption in the United States, the potential for savings is huge."

CITIES are synonymous with noise. But what happens when a city centre becomes a home, a bedroom to 19,000 residents? Noise becomes an issue. Melbourne City Council has spent $70,000 hiring Melbourne University technology experts to draw up plans for a ”wireless sensor network” to measure sounds across the CBD.
Palo Alto, California (CNN) -- In the 1990s, a researcher named Kris Pister dreamed up a wild future in which people would sprinkle the Earth with countless tiny sensors, no larger than grains of rice.

Over the last year I have had the great fortune of mind melding with various people with incredible ideas. As some of you may know, I am involved in Ushahidi, an open source platform for data collection, visualization and interactive mapping. Ushahidi has gotten its notoriety in the crowdsourcing sphere, with growing adoption around the world .

Researchers aim to use humans as wireless nodes
Sensors carried by members of the public could form the backbone of an ultra high bandwidth mobile internet infrastructure - and reduce the density of mobile phone base stations – according to researchers at Queen's University Belfast's Institute of Electronics, Communications and Information Technology (ECIT). Potential applications include remote healthcare monitoring where compact sensors implanted or worn on a patient's body are used to transmit information about their condition wirelessly.Smartphones as sensor platforms
One of the interesting areas for the future development of smartphones is as sensor platforms. I’ve written before about how that might work in consumer health, and Fast Company has an article today about how it might work in consumer finance : RFID credit cards are on the way .You may have heard that the new Google phone (called the Nexus S , built by Samsung) has built in near field communications (NFC). You might not have heard yet the news from yesterday that Google is running an experimental local marketing campaign in Portland which uses the NFC capability. Any business in Portland which has claimed its Google Places Page will be offered a pack of Google goodies which includes an NFC enabled window sticker, and consumers are being incentivised to leave reviews with a prize for the top reviewer.

The software has been developed for smart phones A system which allows psychologists to track people's emotional behaviour through their phones has been successfully road-tested by scientists. St Andrews University researchers have developed in-built phone sensors to work out how people's emotions are influenced by their surroundings.Automotive sensors industry
