New Scientist TV: Giant 3D loom weaves parts for supercar - 0 views

  •  
    It's a sports car few people will be able to get their hands on. In production since last December, only 500 Lexus LFAs will be produced and they were already sold out in early June 2010 (see photo below). But it's not just its top speed of 325 kilometres per hour that's attracting buyers. The car is being used as a test bed for newly-designed parts made from carbon fibre and plastic. Compared to steel or aluminium, it makes the car stronger and lighter but producing these components is much more time-consuming: only one car is currently being assembled per day. One of the key technologies being used is a high-tech circular loom, guided by lasers, that can weave 3D objects (see video above). The machine's futuristic design attracted lots of media attention two years ago, but the video was pulled for fear it would expose company secrets. Now Lexus is revealing how the loom is being used to create complex 3D parts with varying thicknesses and curved shapes. For example, it can create roof rails by weaving fibres around a core, two layers at time, until twelve layers later a hollow roof rail is produced. The piece can then be moulded and injected with resin to create the finished part. The machine was also used to create the car's chassis and front pillars as well as the steering wheel.

    The author makes some important observations that are astoundingly political and may be uncover the core to today's religious interests in science and technology. Major points of interest, when referring to the human eras of social/scientific/technological development: "At each stage, a new resource became available. Something that was previously unknown, unavailable or unusable suddenly became a valuable commodity. In other words, key developments in technology created new resources. The quantity of available resources has continued to expand throughout human history."

Tiny LEDs Pump out Quantum-Entangled Photons | 80beats | Discover Magazine - 0 views

  •  
    LEDsThe strange quantum state of entanglement isn't just challenging to think about, it's hard to create. This "spooky" phenomenon-in which two particles are linked, even if they're separated by distance-can be created by scientists in the lab using bulky lasers. But scientists published a study in Nature today in which they created a light-emitting diode (LED) that produces entangled photons.

Stamping out low-cost nanodevices | KurzweilAI - 0 views

  •  
    A simple technique for stamping patterns invisible to the human eye onto a special class of nanomaterials has been developed by researchers at Vanderbilt University. The new method works with porous nanomaterials that are riddled with tiny voids, which give them unique optical, electrical, chemical, and mechanical properties. There are nanoporous forms of gold, silicon, alumina, and titanium oxide, among others. The technique involves the creation of pre-mastered stamps using traditional, but complex, clean room processes and then using the stamps to create patterns using a new process called direct imprinting of porous substrates (DIPS). DIPS can create a device in less than a minute, regardless of its complexity. The smallest pattern the researchers have made to date has features of only a few tens of nanometers (about the size of a single fatty acid molecule). They have also succeeded in imprinting the smallest pattern yet reported in nanoporous gold, one with 70-nanometer features. The first device the group has created is a "diffraction-based" biosensor that can be configured to identify a variety of different organic molecules, including DNA, proteins and viruses. The researchers envision a wide range of applications including drug delivery, chemical and biological sensors, solar cells, and battery electrodes.

Tactile technology guaranteed to send shivers down your spine | KurzweilAI - 0 views

  •  
    Surround Haptics, a new tactile technology developed at Disney Research, Pittsburgh (DRP) in collaboration with Carnegie Mellon University, makes it possible for video game players and film viewers to feel a wide variety of sensations, from the smoothness of a finger being drawn against skin to the jolt of a collision. The technology is based on rigorous psychophysical experiments and new models of tactile perception. The technology will enhance a high-intensity driving simulator game developed in collaboration with Disney's Black Rock Studio. With players seated in a chair outfitted with inexpensive vibrating actuators, Surround Haptics will enable them to feel road imperfections, objects falling on the car, skidding, braking and acceleration; and experience ripples of sensation when cars collide. They will also experience jumping, flying, falling, shrinking or growing, of bugs creeping on their skin, the researchers said. The DRP researchers have accomplished this feat by designing an algorithm for controlling an array of vibrating actuators in such a way as to create "virtual actuators" anywhere within the grid of actuators. A virtual actuator can be created between any two physical actuators; the user has the illusion of feeling only the virtual actuator, the researchers said. As a result, users don't feel the general buzzing or pulsing typical of most haptic devices today, but can feel discrete, continuous motions such as a finger tracing a pattern on skin. Disney is demonstrating Surround Haptics Aug. 7-11 at the Emerging Technology Exhibition at SIGGRAPH 2011, the International Conference on Computer Graphics and Interactive Techniques in Vancouver, B.C.

New Scientist TV: Amputees regain control with bionic arm wired to chest - 0 views

  •  
    Jesse Sullivan, the man in this video, is using one of the most high-tech prosthetic arms available. But what's truly impressive about it isn't visible to the eye: instead of using a motor, he's controlling the arm with his thoughts. After an amputation, the nerves in a stump remain healthy, at least for a while, and now scientists are making use of this fact to create highly dexterous, thought-controlled prosthetics.

New laser technology could revolutionize communications | KurzweilAI - 0 views

  •  
    Engineers at Stevens Institute of Technology have developed a technique to optically modulate the frequency of a laser beam and create a signal that is disrupted significantly less by environmental factors, says Dr. Rainer Martini. The research provides for enhanced optical communications, allowing mobile units not tied to fiber optic cable to communicate in the range of 100 GHz and beyond, the equivalent of 100 gigabytes of data per second. Eventually, the team hopes to extend the reach into the terahertz spectrum. The frequency or amplitude modulation of middle infrared quantum cascade lasers has been limited by electronics, which are barely capable of accepting frequencies of up to 10 GHz by switching a signal on and off.  Marini and his team have developed a method to optically induce fast amplitude modulation in a quantum cascade laser to control the laser's intensity. Their amplitude modulation system employed a second laser to modulate the amplitude of the middle infrared laser, using light to control light. The current detector is only capable of detecting frequencies up to 10 GHz, but Dr. Martini is confident that a new detector will make the system capable of much higher frequencies. With an optical system that is stable enough, satellites may one day convert to laser technology, resulting in a more mobile military and super-sensitive scanners, as well as faster Internet for the masses, says Martini.

New way to store solar energy for use whenever it's needed | KurzweilAI - 0 views

  •  
    MIT researchers have developed a new application of carbon nanotubes that shows promise as an innovative approach to storing solar energy for use whenever it's needed. Storing the sun's heat in chemical form - rather than first converting it to electricity or storing the heat itself in a heavily insulated container - has significant advantages: in principle, the chemical material can be stored for long periods of time without losing any of its stored energy. The researchers created carbon nanotubes in combination with a compound called azobenzene. The resulting molecules, produced using nanoscale templates to shape and constrain their physical structure, and the concept that can be applied to many new materials. This material is vastly more efficient at storing energy in a given amount of space - about 10,000 times higher in volumetric energy density, making its energy density comparable to lithium-ion batteries, the researchers said.

Safer robots will improve manufacturing | KurzweilAI - 0 views

  •  
    Robots have been considered too unpredictable and dangerous to work alongside humans in factories, but improved technologies for artificial sensing and motion are leading to a new wave of safer robots. Last winter, NASA sent a humanoid robot dubbed Robonaut 2 (R2) to the International Space Station. R2, which has only a torso, sophisticated arms and fingers, and a head full of sensors, jointly developed by NASA and General Motors under a program to create a robot that could operate safely alongside humans. R2 uses a popular robotics technology called series elastic actuators in its joints. The actuators have an elastic spring component between the motor and the object the robot has to pick up. The actuators help the robot detect and control the force of its own movements. R2 is also covered in soft material in case of accidental collisions, and its head contains cameras so it can keep track of its human colleagues. In June, President Obama announced a $500 million federal investment in manufacturing technology (including $70 million for robotics). It represents another step in developing robots that can assist with repetitious or physically stressful assembly-line tasks without posing a safety risk.
