A team of engineers from Purdue University have successfully built a time cloak that hides messages in laser light. This technique is called temporal cloaking and uses lasers and fiber optics to hide data. The technique works by separating strands of light frequencies and slowing photon speed, which allows messages and data to be inserted in gaps created when photons decrease … [Read more...]

High Performance Ceiling Mount Antennas Yields Industry Low Peak Gain
A new multiple-input/multiple-output distributed antenna system has been introduced by Pulse Electronics. This DAS ceiling mount system includes high port-to-port isolation and improved gain patterns for both of its ports. "Often MIMO antennas have problems with non-circular gain patterns with high deviation from min-to-max gains. In MIMO or neutral host applications the … [Read more...]
Generator Line Revitalized
B&K Precision Corporation has announced the rejuvenation of its 4075B series of arbitrary/function waveform generators. The generators now offer higher frequency ranges up to 80 MHz, increased arb memory of 16-Mpt, and a color LCD. Each model can also generate waveforms with a 14-bit amplitude resolution. These new models are ideal for use applications such as sensor … [Read more...]
'Tech Tidbit' – Upgraded Speech Software Allows Paralyzed Physicist Easier Communication
Stephen Hawking, a 72-year-old former professor from Cambridge University, has just received a new upgrade to his computer speech system from engineers at Intel. Hawking relies on computer technology to speak since he suffers from motor neuron disease and is almost fully paralyzed. Currently, he uses a cheek sensor that is synced to his eye glasses that allows him to choose … [Read more...]
'Tech Tidbit' – Wi-Fi Hotspots to be Installed in Public Transportation Systems
A company named Veniam has announced that with the help of True Ventures, it has raised about $4.9 million dollars for a project that will turn buses into Wi-Fi hotspots. This technology has already been introduced in the public bus system in Portugal and the company noted that about 75 percent of passengers use the new technology. With the new capital raised for this project, … [Read more...]
Mechanical Vibrations in Environment Aid in Generating Electricity
A group of research scientists at the VTT Technical Research Centre of Finland announced they have found a new way to generate electricity. This method involves harvesting energy from vibrations in the environment and converting these vibrations into electricity. This was accomplished by connecting the bodies to an external circuit. The researchers generated this energy by … [Read more...]
Custom Cable Assemblies Introduced
New high-performance cable assemblies have been introduced by API Technologies. Features of the custom cable assemblies include a VSWR of less than 1.5:1, an insertion loss that is less than 1db below 50 GHz, and frequencies ranging from 5 GHz to 50 GHz. These cable assemblies are ideal for use in military, aerospace, medical, industrial, and oil and gas applications. “By … [Read more...]
Filter Improves EMC and RCD Compatibility
TDK Corporation has announced its new EMC filter – the EPCOS LeaXield active filter module. This filter minimizes earth leakage currents, which can cause RCDs and negative effects. The LeaXield compensates leakage currents up to 1000 mA and functions in frequencies ranging from 4 kHz to 500 kHz. “LeaXield is now designed for rated currents of up to 150 A for 3-phase grids at … [Read more...]
