FCC Okays Medical Body Networks From dailywireless: The FCC on Thursday announced plans to set aside a chunk of spectrum for connecting wireless medical devices, reports Reuters. The allocation of spectrum for so-called Medical Body Area Networks (MBANs) is part of the FCC’s push to free up unused spectrum and will be up for a vote at the FCC’s May 24 meeting. With wireless medical devices, doctors could monitor a patient’s vital signs at home or in the hospital via low-cost wearable sensors that are attached to the patient’s body and wirelessly connected to the machines that process and display the data for doctors. TheIEEE 802.15 Task Group 6 (Body Area Network) developed a communication standard optimized for low power devices for operation on, in or around the human body. The Philips Heartcycle, a sensor-embedded shirt measuring heart functions, was announced last year. The medical devices lobby pushed the FCC to give it rights to 40 MHz of frequencies, just below the WiFi band. More info here. Like this:
Global Internet Expansion: Who Will Lead the Way? [INFOGRAPHIC] According to recent Cisco research, global Internet traffic will grow nearly four-fold from 2010 -- 2015. However, that increase in traffic won’t be dominated by one region. How much will each region contribute to the worldwide traffic expansion? Just by sheer population size alone, one could assume that the Asia-Pacific region would lead in Internet traffic growth. The infographic below provides an interesting visual projection of what Internet usage will look like in 2015. Tags: 2015, infographic, internet traffic
Pepper-spray cop works his way through art history - Arts Post Posted at 09:13 AM ET, 11/21/2011 Nov 21, 2011 02:13 PM EST TheWashingtonPost Lt. On Friday, Pike casually pepper-sprayed protesters in a video that quickly went viral. Over the weekend, Pike’s visage popped up in Photoshopped into other scenes of languid passivity, such as Edouard Manet’s “Le Dejeuner sur l’Herbe” (The Luncheon on the Grass) pictured above. Archibald Willard’s “The Spirit of ‘76” has a new addition. The images are a cheeky way of fighting back against what students say was an unwarranted use of forceful policing tactics. Online, the damage to his and the university’s reputations may already be done: Kennicott says the video will be among the defining imagery of the movement. Though there are dozens of variations on the pepper-spray cop meme — some inserting him into patriotic moments in history, while others are just mash-ups with other memes — the images of Pike in paintings are effective hyperbole for illustrating his nonchalance in pepper-spraying quiescent protesters.
Loser Generated Content: From Participation to Exploitation | Petersen In this article  some of the critical aspects of Web 2.0 are mapped in relation to labor and the production of user generated content. For many years the Internet was considered an apt technology for subversion of capitalism by the Italian post–Marxists. What we have witnessed, however, is that the Internet functions as a double–edged sword; the infrastructure does foster democracy, participation, joy, creativity and sometimes creates zones of piracy. But, at the same time, it has become evident how this same infrastructure also enables companies easily to piggyback on user generated content.

2011 September Latest Research in Wearable Technology: Video Demos and Abstracts Some of the latest research applications in wearable and ubiquitous technology were submitted and presented at EMBC’s UnConference this year. All entries submitted a project abstract and many have included a short demo video illustrating the research and technology in action. The videos provide a real insight into some of the emerging applications in wearable technology from integrating sensors in textiles, mobile phone based sensing, non invasive cardiovascular reactivity measurement, and body worn monitoring tailored to a range of domains. Awards were presented to Nizan Fridman for ‘MusicGlove: A Music-Based Device for Hand Rehabilitation and Quantitative Assessment of Hand Function’ for the most innovative demo, and to Virg Bento for ‘The SWORD ambulatory rehabilitation system’ for the highest potential impact demos. The pieces are falling into place for an “internet of things” From GigaOM: More info here. More info here.
Mozilla asks users to join ‘Stop SOPA & PIPA’ campaign The end of the Internet as we know it may be right around the corner — but not if the Mozilla Foundation has anything to say about it. The maker of Firefox, a non-profit organization, has launched a campaign to help block the passage of both the ‘Stop Online Piracy Act’ (SOPA) and the ‘Protect IP Act’ (PIPA), each of which may soon go up for a vote in Congress. Those who join the campaign are asked to call their senators and representatives and express their ardent opposition to these bills by this Tuesday. What are SOPA and PIPA, anyway? Both PIPA and SOPA aim to crack down on websites that illegally distribute copyrighted material, like movies, songs and TV shows, just as the 1998 Digital Millennium Copyright Act (DMCA) tried to accomplish in the past. Supporters and critics Other possible consequences of SOPA and PIPA Conclusion In short: SOPA and PIPA would likely do little to achieve their explicit goals of curbing online piracy. Watch an in-depth video explanation of PIPA

Interactivity is Evil! A critical investigation of Web 2.0 | Jarrett Central to Web 2.0 is the requirement for interactive systems to enable the participation of users in production and social interaction. Consequently, in order to critically explore the Web 2.0 phenomenon it is important to explore the relationship of interactivity to social power. This study firstly characterises interactivity in these media using Barry’s (2001) framework differentiating interactivity from disciplining technologies as defined by Foucault. Contrary to Barry’s model though, the analysis goes on to explore how interactivity may indeed function as a disciplining technology within the framework of a neoliberal political economy. Table 1 Interactivity and Web 2.0 These ‘non–disciplinary’ features of interactivity can be readily traced within the participatory media of Web 2.0.

Electric Imp Takes the ‘Internet of Things’ Mainstream From Fellow Geek: Today a new startup came out of stealth mode. Called Electric Imp, they have developed a line of products designed to connect anything and everything together. and they might finally take the internet of things into the mainstream. Electric Imp sells a series of small microcomputers that resemble SD cards. In them is a Wifi antennae and a processor. You plug them into other circuits that Electric Imp also sells, which do various things. By breaking the processing out of the sensors, you get a product that can be built to do whatever it is you desire. Everything is controlled from the cloud by a drag-and-drop interface. Don’t really care about networking your Christmas lights to the light level? But how do you connect the Imp to the network in the first place? I’m still not convinced that the internet of things will take off. But if any product is going to make it mainstream, it would be the Electric Imp.

Data Reveals That “Occupying” Twitter Trending Topics is Harder Than it Looks! While the Occupy Wall Street (OWS) movement has been gaining momentum, growing in terms of visibility, media coverage and sheer numbers of participants, it has had a difficult time “occupying” the Twitter trending topics (TTs) list. #OccupyWallStreet, the movement’s dominant hashtag, has never once hit the New York TTs list. Similarly, #OccupyBoston has trended all across the world, but never in Boston, which only saw the phrases ‘Dewey Sq’ and ‘Dewey Square’ trend. Some point the blame at Twitter for censoring content, yet what seems to be happening is purely algorithmic. There’s often more than meets the eye when it comes to algorithmically generated TTs. In this post we dissect some of the dynamics at play, looking at all OWS related terms that have trended on Twitter since the start of the movement, their volume of appearance in tweets, and the times and locations they’ve trended. What’s in a Trend? Censorship? Interesting. #OccupyWallStreet – A closer look Competing for Attention
Net Neutrality: la Discusión de los Estados Unidos | Neutralidad SI ! La Neutralidad En La Red es un hot topic en la sociedad civil e informática de los Estados Unidos. Según la Wikipedia, el término “Net Neutrality” fue acuñado por la Ley Europea de Telecomunicaciones en el año 2003, y luego llevada al país del norte a través de la Federal Communication Comission (FCC) cuando decidió reclasificar a los proveedores de acceso residencial DSL como Servicio de Información al prestar también servicios de TV por Cable. La naturaleza de la discusión en los Estados Unidos no difiere en esencia de lo que discutimos hoy en Chile. Los proveedores de acceso a Internet se deben limitar tan solo a proveer dicho acceso, estando totalmente fuera de su competencia el privilegiar o entorpecer el acceso a ciertos contenidos. En la forma, la discusión dista de lo que sucede hoy en Chile, sin embargo, eso no quiere decir de ninguna manera que podamos estar exentos de la posibilidad que ocurra lo mismo en nuestro país. El problema no termina ahí. ¿Que puede suceder en Chile?
