Bosch's reworked automotive sensors can help control flying taxis
As companies from Boeing and Uber to Lilium work to develop flying taxis, Bosch wants to make the sensors they'll require more accessible. The company says conventional aerospace technology is too expensive and bulky to use in autonomous flying vehicles. So, today, Bosch announced a plug-and-play sensor box that adapts automotive industry sensors for use in flight.
IMEC working with holograms, mirrored pixels to prevent 3D movie headaches
Let's face it, 3D movies are amazing but there are times when you'll walk away with a killer headache. A group of researchers at IMEC believes that holographic video might be the best way around this problem and has been working on a means of constructing holographic displays by shining lasers on microelectromechanical systems (MEMS) platforms capable of moving up and down like small, reflective pistons. Here's the cool part: each pixel would have a spring-like mechanism attached to it that could be moved by applying voltage to it. In the first stage of the technology, a laser is bounced off a MEMS-less chip containing an image, the diffracted light interfering to create a 3D picture. From here, the team can adjust the image by replacing pixels with small, mirrored platforms that can alternate their direction to create a moving projection. It gets technical after this, but you can take a gander at the video after the break for a full demo and explanation.
World's smallest violin uses MEMS, plays only for you (video)
You might not have heard of microelectromechanical systems (MEMS), but there are likely a bunch in your new smartphone -- they make possible the tiny accelerometers and gyroscopes needed to detect motion as your device swings around. However, last week students at the University of Twente demonstrated a brand new micrometer-scale system: a tiny musical instrument that plucks strings (those "folded flexures" above) one-tenth of a human hair wide. Six microscopic resonators fit on a microchip, one resonator per musical tone, and series of the chips can be combined into a MIDI interface to play entire songs. Though the micronium needs to be amplified 10,000 times before they're audible through standard speakers, the instrument's the real deal -- watch it play a wide selection of tunes (including some Mario Bros) in a video after the break. One burning question remains, however: is this nano-violin open source?
MEMS-based smart fuses could guarantee desired explosions
While we certainly hope the average (read: not GI) jane / joe isn't overly concerned about the rate at which homegrown explosions detonate as desired, we understand the Army's need to have more faith in their own munitions. Reportedly, a new "smart fuse" conjured up at Georgia Tech could soon prevent bombs from experiencing fuse failure by using "semiconductor fabrication equipment to make hundreds of ultra-high precision detonators on a wafer at the same time." In addition to cutting down on the use of toxic heavy metals and increasing the safety of weapon production, the intelligent MEMS fuse will supposedly "incorporate built-in arm and fail-safe mechanisms that virtually guarantee that munitions go off when they should, every time." Weapons that fire when needed -- now there's a concept. [Image courtesy of Rich's Incredible Pyro]
Secrets of levitation cracked by Scottish researchers?
Try not to get too frenetic here, but a couple of gurus at the University of St. Andrews in Scotland have reportedly created an "incredible levitation effect by engineering the force of nature which normally causes objects to stick together." In layman's terms, the scientists have devised a way to reverse the phenomenon known as the Casimir force so that it "repels instead of attracts." Ultimately, the discovery could lead to "frictionless micro-machines with moving parts that levitate," and in theory, devices could be created to transport humans. Do realize, however, that individuals in this team have also "showed that invisibility cloaks are feasible," so we're not counting ourselves amongst the faithful just yet.[Thanks, James][Our readers have let us know that this article's headline bore some similarities to other articles on the same topic -- though purely coincidental, in the interest of further differentiating the post we've edited it to a small degree. -Ed.]
