The Miro 3 High-Speed Digital Camera - making the invisible visible

May 11, 2007 Vision Research showed off a very special new camera at the recent NAB in Las Vegas, and SAE World Congress in Detroit - the first in a new line of Phantom high-speed digital cameras. The Phantom Miro line is a compact, light-weight, rugged family of cameras targeted at industrial applications ranging from biometric research to automotive crash testing. Rated to survive 100g acceleration this rugged camera can take 512x512 images at up to 2200 frames-per-second (fps). Reduce the resolution to 32 x 32 and achieve frame rates greater than 95,000 fps. With an ISO rating of 4800 (monochrome, saturation-based ISO 12232), the camera has the light sensitivity for the most demanding applications. With shutter speeds as low as 2 microseconds, the user can freeze objects in motion, eliminate blur, and bring out the image detail needed for successful motion analysis. The camera accepts any standard 1" C-mount lens. See a movie of what it can do here. Read More

Scientists move a step closer to being able to make objects invisible

May 4, 2007 A computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range. Scientists have already created an ‘invisibility cloak’ made out of ‘metamaterial’ which can bend electromagnetic radiation – such as visible light, radar or microwaves – around a spherical space, making an object within this region appear invisible. Until now, scientists could only make objects appear invisible from far away. Liverpool mathematician Dr Sebastien Guenneau, together with Dr Frederic Zolla and Professors Andre Nicolet from the University of Marseille, have proven - using a computer model called GETDP - that objects can also be made to appear invisible from close range when light travels in waves rather than beams. Scientists predict that metamaterials could be of use in military technology, such as in the construction of fighter jets and submarines, but it will be some years before invisibility cloaks can be developed for human beings.Read More

Invisible sound from Bang & Olufsen

February 26, 2007 Adding further validity to the “sound systems should be heard and not seen” school of thought is the news that long-term discerner of public taste Bang & Olufsen is to release a passive loudspeaker that can be placed in places where active loudspeakers fall short. Bang & Olufsen has played a leading role in the evolution of entertainment systems and its BeoVox 1 points to the future of home entertainment. Being a built-in loudspeaker, BeoVox 1 fits nicely and discreetly in hallways or rooms where you do not have much space. It can be completely concealed in the walls or in the ceiling. It's extremely well suited for places where the primary activity is not listening to music, but where you'd still like to have music either as secondary entertainment or background sound. Another product from the imagination of designer David Lewis, the two-way passive system includes 1” treble unit and a 6” mid-range/bass unit, delivering a frequency range of 50-20,000 Hz.Read More

'Invisible' Loudspeaker Technology

April 1, 2005 Sonance, the company that originated high fidelity in-wall loudspeakers some 22 years ago, has acquired the IP of its major competitor Sound Advance Systems for “invisible” loud speaker technology. These technologies offer a range of unique and compelling loudspeaker features in that they are completely undetectable and provide a wide, virtually omnidirectional sound dispersion pattern and are ideal for applications requiring background and foreground music, voice paging, surround sound, and multi-room systems. Sound Advance speakers can be found in such exclusive locations as the Dolce & Gabana, Luis Vuitton, Prada, Armani and Chanel boutiques in cities such as Milan, Paris, New York, Beverly Hills, and St. Moritz, and have been the centerpiece of numerous CEDIA Electronic Lifestyle award winning residential installations.Read More

Invisible digital post-it notes

February 12, 2005 In the future, cell phone users will be able to leave messages anywhere in the form of what might be termed electronic post-its. They will be able to post virtual messages referring to a specific location wherever they are needed. Siemens researchers have now created the technical basis and the computer programs for this "digital graffiti service." Post-its are exceedingly practical. They're a handy way of letting people know if you've gone out quickly to shop or to lunch, or for reminding you to do things. However, you can't stick these yellow memos in mid-air - at least not yet. But that will be possible in future with the virtual post-its from Siemens Corporate Technology's research laboratory in Munich. Dieter Kolb's team of specialists have developed computer programs that assign cell phone messages to specific locations. Read More


Insect-Repellent Apparel provides invisible defence

Wednesday August 6, 2003: A range of clothing that incorporates insect repellent into its fabric has been recognised by the Environmental Protection Agency (EPA) in the US. BUZZ OFF apparel is manufactured using a special process that binds the repellent tightly to the garment, resulting in an invisible, odourless layer of protection around the wearer.Read More
