Silicon Labs has recently published a white paper on 5 important guidelines for selecting the right size battery for wireless IoT sensors. Check it out here. … [Read more...]
New Methods Minimize Interference on TV Broadcasting and Mobile Connections
A research project recently conducted by VTT Technical Research Centre of Finland Ltd. allows an optimal location to be identified for wind turbines, where interference on television broadcasting and mobile connections is minimized. “With tools now available for minimizing the potential negative impacts of wind power at the planning stage, power plant projects are likely to … [Read more...]
‘Electrosmog’ to Help Power Devices in UK
Paul Drayson, a former British science minister, has developed a device that captures “electrosmog” (invisible clouds of electromagnetic radiation), and uses it to power small devices. The energy-harvesting system is known as Freevolt. Freevolt uses an antenna to gain power from multiple wavebands of the electromagnetic spectrum. This is the first commercial device that is … [Read more...]
New Multi-Range System DC Power Supply Model
B&K Precision has introduced an addition to its 9115 Series with the new multi-range programmable DC power supply—model 9117. The new 9117 can deliver up to 3000 W of output power in any combination of voltage up to 80 V and current up to 120 A within its power rating. It offers twice as much output power as current models in the 9115 series and has a 2U 19" rackmountable … [Read more...]
GaN Coaxial Power Amplifiers
Pasternack recently launched its increased offering of gallium nirtride (GaN) coaxial power amplifiers. “The high power density of gallium nitride semiconductor technology dissipates heat more effectively which results in amplifier designs that have significantly higher output power levels over broadband and narrowband frequencies,” according to the company. This technology … [Read more...]
New Metamaterial Yields Invisibility for Aircraft and Drones
Electrical engineers from the University of California have created a new ultra-thin metamaterial that could provide a cloaking device and make UAVs (Unmanned Aerial Vehicles) invisible. The new material creates invisibility and leaves no electronic, infrared or visual signatures for enemies to detect. The new design uses “an ultra-thin Teflon substrate, studded with … [Read more...]
3D Printing Can Add Circuitry
Researcher Michael Perrone is currently testing a prototype of one of the world’s most advanced 3D printers, which was built by a startup company known as Voxel8. The 3D printer is not on the market yet, but it can produce small objects out of plastic while simultaneously adding circuitry to them. The printer was produced last month in a lab at Harvard University. During … [Read more...]
High-tech Highways Could Charge Electric Cars While Driving
The United Kingdom is currently testing technology that would allow high-tech highways to recharge electric cars as users are driving. “The U.K. has already tested a bunch of different approaches to this technology and identified versions that work and are ready to manufacture. In basic terms, the system has power lines connected to coils under the surface of a road, which … [Read more...]
High Power Coaxial Limiters Handle up to 200 Watts
Fairview Microwave Inc. announces a new family of broadband, high power coaxial limiters that protect sensitive components and RF receivers that are close to high power signals. Depending on the model, the limiters operate on frequencies ranging from 0.5 GHz to 40 GHz. The limiters also offer seven different design options, a low leakage power of 10 to 15 dBm and limited … [Read more...]
Report: Data can be Hacked Via Sound Waves
A security expert has reported that data can be hacked and transmitted by using sound waves. “Attackers could make use of the physical elements of common input/output circuits - not only in computers but in printers, aircon units, and all kinds of other devices - by vibrating them at a pre-decided frequency. Effectively, they would be turned into radios,” Reuters reported. … [Read more...]
