    nice way to convert transversal force in lateral. They use it for high forces (up to 500 N). Would it (Bragg fiber) work for milli N ?

      Right man! It's interesting to see that these instruments are also needed to almost all robot-assisted surgery procedures. So it's more than just brain manual surgery.

  • the development of marketing is sensible to its environment and is hence already self-limiting itself according to the previously mentioned legal and social framework
  • neuromarketing
  • explore new inner dynamics of marketing, new directions in the field of possibilities offered by the current organology and its articulations between techniques and social organization in order to influence and shape marketing as an associative force – in opposition to its current dissociative force – in the larger psychic, social and technic organology
  • ...70 more annotations...
  • find new ways of efficiency
  • arbitration between efficiency and care
  • a global thinking of the problem
  • Fighting the attention and desire resource shortage: stoping to use advertisement?
  • The question is rather here to think the moderation of the psychopower
  • empower transindividuation, i.e. to make sure that an economic activity creates more possibilities of individuation than it tend to destroy by attempting to capture attention and canalize motivation in a funnel. Empower transindividuation would imply to empowering actors of their own lifestyle, winning back the savoir-vivre prescribing production
  • Should marketing stop using psychopower?
  • marketing ethics guidelines
  • transactions are more likely to be morally defensible if both parties enter it freely and fully informed
  • the goal of marketing should be to increase the likelihood and frequency of free and informed transactions in the marketplace
  • putting freedom as a criteria of morality
  • the industrial use of pycho- and neuropower tend to fall under the category of barriers to freedom
  • neurotechniques – to capture the attention
  • psychotechniques – to attempt to create motivation
  • Most people think commercials are a small price to pay for these benefits
  • advertising
  • denying the schemes of addiction and the fact that we are becoming through the objects of attentions
  • right to avoid attention capture by advertising
  • progress made in cognitive sciences proving that
  • reward system being abnormally stimulated
  • Advertisements exploit
  • vulnerability and reinforce their overconsumption behaviors
  • “if food advertising on TV were banned, significant reductions in the prevalence of childhood obesity are possible.” (Veerman et al. 2009)
  • What is at stake falls to be much more complex than the sole Freedom of Speech invoked for the advertiser
  • liberty of non-reception
  • would mean to guaranty every citizen the right to choose where and when he wants to access the advertising information
  • Change in the industrial and commercial paradigm
  • Economy of contribution and peer production
  • An economy of contribution means that users of a service are contributing to the production of these services.
  • example
  • is open-source software that are contributively build by potentially hundreds of developers organized in communities
  • minimize the gap between the producer and consumer
  • blur the frontier between professionals and amateurs
  • The Copernican revolution of the Vendor Relationship Management paradigm
  • change in the commercial paradigm, described as an Intention Economy i.e. the opposite of the Attention Economy
  • consumers are charged to express and discuss their intention
  • with businesses rather than the usual paradigm in which businesses where fighting for a piece of canalized motivation
  • Implementing such a system would nevertheless imply that marketing departments dispose of a system in which they could value their supplies and where they could be easily found by customers. Doc Searls promotes his answer to this issue: the Vendor Relationship Management system.
  • the belief that free customers are more valuable than captive ones — to themselves, to vendors, and to the larger economy.
  • To be free
  • 1. Customers must enter relationships with vendors as independent actors.
  • 2. Customers must be the points of integration for their own data.
  • 3. Customers must have control of data they generate and gather. This means they must be able to share data selectively and voluntarily.
  • 4. Customers must be able to assert their own terms of engagement.
  • 5. Customers must be free to express their demands and intentions outside of any one company’s control.
  • This is a profoundly game-changing approach
  • big data that is the rush for consumers’ information potentially leading to the same dead-end of attention destruction and affective saturation than the former offline paradigm
  • VRM system working as a marketplace
  • the goal of marketing should be to increase the likelihood and frequency of free and informed transactions in the marketplace
  • less imperfect and less biased information in a cultural context overvaluing transparency, and a bigger atomicity due to the hereafter introduced trend for re-localized peer production.
  • 3.2.2.3 VRM and externalization of the socialization process
  • Promoting the end of advertisement
  • means to find a new way to make the information circulate, what was the primary goal of advertisement
  • Until there is no alternative to massive advertisement campaign for the information circulation, it is indeed hard to ask entrepreneurs and managers to get rid of those successors of propaganda: such a transition process necessarily imply adaptation costs from the producer and the consumer side, and possible competitive disadvantage against competitors still maximizing profit through advertisement means
  • But the internet transformation of the general organology offers new way to think information circuits and potentially constitute an opportunity to externalize the socialization process of products that is to empower citizen-consumers organized in communities
  • Empowering groups of citizen doesn’t annihilate the risks of mis-use or counterproductive interest-taker behaviors but a well-designed system of trust between peers could minimize this risk by creating a dependency to what social capital other peers give you, as it is happening in the sharing economy: the credibility of a contributive peer would be guaranteed through what the P2P Foundation calls Feedback systems and peer-police
  • a strong structuration of products characteristics, allowing customers to personalize their choices according to their desire and constraints: such a “VRM+” system
  • Marketing would then be the art of being as high as possible in this ranking, as it is happening in SEO for search engines, but in this context of criteria explosion, marketing would then be the disciple of listening to customers’ wishes and aspiration needing an attention, in order to kick in the production or to adapt the following series.
  • 3.2.2.4 Toward a possible equi-power
  • Such a system would tremendously re-configure the balance of power and tend toward a form of equi-power i.e. a social organization in which abuses of a “big” would be the potential object of a ranking sanction by the peers
  • self-regulative function
  • a form of economic Darwinism would let to conscious organization the right to curve their path toward a durable configuration in accordance with the social ecosystem.
  • the idea of equi-power is a form of homogenization of the social matter, in which the distortions in the balance of power would be compensated by the gathering of small forces sharing a common interest
  • Such a sanction systems, if successfully implemented, would make value-destructing businesses progressively decline and hopefully bankrupt,
  • long-term valuable strategic choice
  • long term satisfyingly high ranking
  • It would be utopic to think that the “being cool” marketing
  • would disappear, but marketers would have to make those two objectives compose together.
  • This social capital contagion is nevertheless a tool that would need to be controlled in its form of violence by extensive testings and iterations with forms of protections for the smallest peers, that is to say to keep this form of social violence to institutionalized, classic forms of businesses, clearly beyond the line of what should be acceptable in the global village.
  • the goal is here to create an artificial form of majority that is a self-censuring responsible behavior of corporations

  • for In Vivo and In Vitro Isometric Force Measurements and Isotonic Displacement Measurements
  • Four-bonded strain gages form a rugged bridge which measures the strain produced on a cantilever beam by the force applied. The housing is rugged and the handle can be clamped. Gravity effects are reduced to one dimension. High natural resonance is afforded by the cantilever. There are no pivots — no friction.

robot touch aids cancer surgery

shared by Francois Bergeron on 25 Apr 12 - No Cached
  • Surgeons have developed new minimally invasive surgery (MIS) techniques and instruments so that procedures that would previously have required a large incision can now be performed through a tiny 10mm cut.
  • University of Western Ontario and Canadian Surgical Technologies and Advanced Robotics (CSTAR) in London, Ontario
  • The researchers used a torque sensor to measure the force of the palpations.
  • ...2 more annotations...
  • Using tactile MIS sensing instruments under robotic control reduces the maximum force applied to the tissue by over 35% compared to a human controlling the same instrument. Accuracy in detecting the tumours was also far greater with the robot - between 59 and 90% depending on the robot control method used for palpation.
  • If developed further, the authors suggest that this type of instrument would particularly benefit surgeons performing lung tumour resection, where tissue often shifts significantly.

    Machines talking to machines No doubt that the Olympics will have a profound effect in shaping London's future. By the time the Games begin, for instance, it will have Europe's largest free WiFi zone, with the city's iconic red phone booths converted, fittingly, into hotspots. But another opportunity London landed earlier this month could have just as much impact, perhaps more. A company called Living PlanIt announced that it will begin testing its "Urban Operating System" in the Greenwich section of the city. What does that mean? Put simply, London would have its own operating system, much as your PC runs on Windows or your Mac runs on Apple's IOS. This ties into the latest hot buzz phrase, "the internet of things," which describes a world where machines talk to other machines. No human interaction required. So, for a city, this means sensors in buildings would connect to sensors in water treatment plants which would connect to sensors in stoplights. It would be one gigantic, computerized urban nervous system, which a lot of experts think is the only way cities can survive a future when they'll contain more than two out of every three people on Earth. Based on what sensors reveal about the location and movement of humans in a section of a city, for instance, buildings will automatically adjust their temperatures, streetlights will dim or brighten, water flow will increase or slow. Or, in the event of a disaster, emergency services would have real-time access to traffic data, trauma unit availability, building blueprints. And soon enough, our smart phones will be able to tap in to the Urban OS. So will our household appliances. This is not some 21st century analogue of the personal jet pack. The Urban OS is the driving force behind a smart city being built from the ground up in northern Portugal. Construction is scheduled to be completed in three years; eventually it will have about 150,000 residents. It will also have more than 100 million sen
