Whether the need is remote access to data on a home network or to turn an entire classroom into a highly interactive learning environment, the solution is simple, convenient, and inexpensive. With a small form factor server called a plug computer, network connectivity is right at a wall socket. Simply insert the plug computer into an electrical outlet and add an external hard drive or a USB flash drive through a USB port (depending on the deployment, a router may also need to be connected) — just like that, you have a network attached storage device. Powered by Marvell embedded processors, a plug computer is packed with enough processing power and network connectivity for managing and serving up digital media files.
It also draws less than one tenth of the power consumed by its PC counterparts enabling always-on, always-connected, and environmentally friendly computing. Applications for a plug computer include: Media Server Home Automation Remote Access A micro cloud for the classroom. TinyOS Home Page. NASA investigates use of graphene for new sensors.

(Credit: NASA/Pat Izzo) NASA researchers have developed graphene-based sensors to detect trace elements in Earth’s upper atmosphere and structural flaws in spacecraft. Technologist Mahmooda Sultana at NASA’s Goddard Space Flight Center is investigating nano-sized detectors that could detect atomic oxygen and other trace elements in the upper atmosphere and structural strains in everything from airplane wings to spacecraft buses. “The cool thing about graphene is its properties,” said Jeff Stewart, the acting assistant chief for technology for Goddard’s Mechanical Systems Division. “It offers a plethora of possibilities. Graphene is just one atom thick and composed of carbon atoms arranged in tightly bound hexagons best visualized as atomic-scale chicken wire. Chemical Sensors. A low-cost, implantable electronic biosensor. Field effect transistor protein biosensor schematic.
A sensing channel connects the source (S) and drain (D) with a reference electrode (RE). When a target analyte (protein) binds to the receptor, it induces charges in the substrate, causing a change in the current ﬂow between the source and drain (a protein detection). (Credit: Ohio State University) Ohio State University engineers are developing low-cost electronic devices that work in direct contact with living tissue inside the body. The initial objective is to develop an in vivo biosensor to detect the presence of proteins that mark the first signs of organ rejection in the body. Doctors would insert a needle into the patient’s body near the site of the implanted organ. While other more exotic semiconductors might work in the body, they are more expensive, harder to manufacture, and may be toxic, he said. Protective coating The university will license this technology for further development.
SCiO - Consumer Physics. Fear of Repression Spurs Scholars and Activists to Build Alternate Internets - Technology. By Jeffrey R. Young Washington Computer networks proved their organizing power during the recent uprisings in the Middle East, in which Facebook pages amplified street protests that toppled dictators. But those same networks showed their weaknesses as well, such as when the Egyptian government walled off most of its citizens from the Internet in an attempt to silence protesters. That has led scholars and activists increasingly to consider the Internet's wiring as a disputed political frontier. For example, one weekend each month, a small group of computer programmers gathers at a residence here to build a homemade Internet—named Project Byzantium—that could go online if parts of the current global Internet becomes blocked by a repressive government. Using an approach called a "mesh network," the system would set up an informal wireless network connecting users with other nearby computers, which in turn would pass along the signals.

The concept of the "sensor web" is a type of sensor network that is especially well suited for environmental monitoring. The phrase the "sensor web" is also associated with a sensing system which heavily utilizes the World Wide Web. OGC's Sensor Web Enablement (SWE) framework defines a suite of web service interfaces and communication protocols abstracting from the heterogeneity of sensor (network) communication. Definition Characteristics of Delin's sensor web architecture Delin designed a sensor web as a web of interconnected pods.
All pods in a sensor web are equivalent in hardware (there are no special "gateway" or "slave" pods). Nevertheless, there are additional functions that pods can perform besides participating in the general sensor web function. The term of mother pod refers to the pod that contains the master clock of the synchronous sensor web system.
Each pod usually contains: See also References Further reading External links Semantic Sensor Web | Kno.e.sis. Millions of sensors around the globe currently collect avalanches of data about our environment. The rapid development and deployment of sensor technology involves many different types of sensors, both remote and in situ, with such diverse capabilities as range, modality, and maneuverability. It is possible today to utilize networks with multiple sensors to detect and identify objects of interest up close or from a great distance. The lack of integration and communication between these networks, however, often leaves this avalanche of data stovepiped and intensifies the existing problem of too much data and not enough knowledge.
With a view to alleviating this glut, we propose that sensor data be annotated with semantic metadata to provide contextual information essential for situational awareness. In particular, we present an approach to annotating sensor data with spatial, temporal, and thematic semantic metadata. Research Topics Semantic Modeling and Annotation of Sensor Data People.

A sensor grid integrates wireless sensor networks with grid computing concepts to enable real-time sensor data collection and the sharing of computational and storage resources for sensor data processing and management. It is an enabling technology for building large-scale infrastructures, integrating heterogeneous sensor, data and computational resources deployed over a wide area, to undertake complicated surveillance tasks such as environmental monitoring.
Concept and history The concept of a sensor grid was first defined in the Discovery Net project where a distinction was made between “sensor networks” and “sensor grids”. Uses The sensor grid enables the collection, processing, sharing, visualization, archiving and searching of large amounts of sensor data.     There are several rationales for a sensor grid.

FreedomBox. FreedomBox is a community project to develop, design and promote personal servers running free software for distributed social networking, email and audio/video communications. The project was announced by Eben Moglen at the New York ISOC meeting on February 2, 2010. On February 4, 2011, Moglen formed the FreedomBox Foundation to become the organizational headquarters of the project, and on February 18, 2011, the foundation started a campaign to raise $60,000 in 30 days on the crowdfunding service, Kickstarter. The goal was met on February 22, and on March 19, 2011, the campaign ended after collecting $86,724 from 1,007 backers. The project currently describes a FreedomBox as The developers aim to create and preserve personal privacy by providing a secure platform for building federated social networks. This shall be done by creating a software stack that can run on plug computers that can easily be located in individual residences or offices.

CloudPlug, a plug computer developed by CTERA Networks Seagate Dockstar, a plug computer similar to the SheevaPlug Suitable for running a media server, back-up services, file sharing and remote access functions, such devices can be used as a bridge between in-home protocols such as Digital Living Network Alliance (DLNA) and Server Message Block (SMB) and cloud based services. Plug computers typically consume little power and are inexpensive.
One manufacturer claims its $119 plug computer draws 1.2 watts and can cost $2 a year to run. The low cost of plug computers has led to a proposed "FreedomBox", an always-on home server configured to keep communication private in the face of government surveillance. History A number of other devices of this type began to appear at the 2009 Consumer Electronics Show. See also References External links Media related to Plug computers at Wikimedia Commons. H:D. The Past, Present, and Future of Data Storage. As we approach the end of 2011 and look forward to another year, we pause to reflect on the long history of data storage. Mankind's ability to create, process, store, and recall information is light years ahead of the days of cave paintings and engravings on stone tablets. Vast amounts of information can be stored on drives smaller than your thumb, and data centers are cropping up at an increasingly high rate.
What does the future of data storage hold? Are we really that close to holographic drives? Is 2012 the year SSDs become mainstream?
