A seven car Maglev (magnetic levitation) Train in Central Japan broke its own speed record when tested near Mount Fuji this week. In 2003 the Maglev’s record was 268 mph and last week it reached 366 mph. On Tuesday the Maglev surpassed both previous records and reached 374 mph. The Maglev train hovers four inches above the tracks and is propelled by electrically-charged … [Read more...]
Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
FBI Pulled Security Expert from Flight for Alleged Hacking Concerns
The FBI pulled Chris Roberts, a computer security expert, from his United Airlines Flight last Wednesday in Syracuse because of suspicions that he hacked the airplane. Roberts tweeted referencing the plane’s communication systems suggesting he was going to use his laptop to force the plane’s emergency oxygen masks to deploy. The tweet read: “Find Myself on a 737/800, let’s see … [Read more...]
Harmonic Comb Generators Are Useful Tools
By Kenneth Wyatt INTRODUCTION One tool every EMC test lab should own is a harmonic comb generator. A comb generator is simply a device that will produce a set of harmonically related CW signals whose spacing is based on a fundamental oscillator frequency. For example, if we were to start with a 10 MHz clock oscillator and feed the digital output into a coax connector, we’d … [Read more...]
New Bill Could Affect Road Safety Technology
The U.S. government says Wi-Fi contributes to more than $140 billion of economic activity per year and demand is growing for the limited available spectrum, according to CBS news. A new bill has been drafted to fix this problem. Lawmakers plan to open a Wi-Fi space for the public; however, it could negatively impact vehicle-to-vehicle commutation (V2V) technology, which … [Read more...]

Inventor Plans to Rid the World of the Power Cord Forever
Meredith Perry, an inventor from New Jersey, has introduced her plans to “get rid of the power cord.” Perry has been working on a project at her company, uBeam, that involves producing a method to charge electronic devices over thin air. Ultimately, the uBeam Transmitter was born. "The dream is to replace all electrical outlets with uBeam transmitters. You'll wake up and just … [Read more...]
Newly Produced Hoverboards Use Magnetic Energy to Hover
Technology to support real-life Hoverboards is rapidly emerging. The Hendo Hoverboard uses magnetic energy to hover and is the first real step towards creating a board similar to Marty McFly’s board in the popular 1985 movie “Back to the Future.” The Hendo Hoverboard is not as compact as the one in the movie – it’s bigger, less maneuverable, needs metal underneath it, and … [Read more...]
