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...]
EMI/EMC Power Filter Line Expands
API Technologies has expanded its power filter family with the introduction of new two-line, two-stage, EMI/EMC power filters designed for use in ground-current-sensitive applications. The filters offer a rated voltage of 250(50/60Hz) and an operating temperature range of -40 to +85 degrees Celsius. Other features include “withstanding voltage is 4000V AC or 1500V AC for one … [Read more...]
EMC Test Lab Expands; Now Fully Accredited
Retlif Testing Laboratories, an independent test lab in Ronkonkoma, N.Y., announced it is expanding its EMI/EMC compliance testing laboratories. Retlif has finalized the accreditation process and is now fully accredited to IS0-STD-17025 for its Composite Testing Laboratories. “Administered by the Laboratory Accreditation Bureau (L-A-B), the accreditation enables a broader … [Read more...]
Wireless Testing Lab Opens in China
Bureau Veritas announced it has opened a Wireless/Smartworld Lab in Shenzhen, China. The company’s current footprint covers the U.S., Germany, France, Korea, Taiwan, and now China. “With 7 out of the top 10 global smartphone brands being Chinese, Shenzhen being one of China's three technology hubs and one of China's Smart Cities, Bureau Veritas' latest wireless/smartworld lab … [Read more...]
African Village Burning Rituals Help Identify Reason for Magnetic Field Weakening
A team of scientists has reported that ancient village burning rituals that took place during the Iron Age have provided evidence of what could have possibly caused the weakening of the magnetic field in South Africa. Scientists discovered that a hot and dense rock 2,000 miles beneath the surface that is 4 miles wide is the cause of Africa’s magnetic field weakening. “The … [Read more...]
Outdated 2G Mobile Phones Could be Used to Hack Computers
A team of computer security experts from Ben-Gurion University in Israel have discovered 2G mobile phones could hack air-gapped computers and steal data via radio frequency wireless electromagnetic waves and a GSM network. In order for this process to work properly, both the 2G phone and the targeted computer must have malware installed on them. “Computers naturally emit … [Read more...]
Robots to Help Build Radio Telescope for Far Side of Moon
Researchers are making progress in building a radio telescope array that would be placed on the far side of the moon by a robot. The robot, or rover, would be controlled by NASA astronauts in the Orion spacecraft. A team at the University of Colorado Boulder, lead by Jack Burns of the Lunar University Network for Astrophysics Research (LUNAR), has developed a system that … [Read more...]
Testing Reveals Microwaves May Launch Aircraft into Space
A team of researchers from Escape Dynamics in Colorado have announced test results indicate microwaves might be able to launch space planes into space, which would allow for a single stage spacecraft. If this idea works, it would significantly reduce costs, because sending satellites and humans into orbit is typically very expensive. “Today's rockets are all based on the same … [Read more...]
New Waveguide Detectors Cover Frequency Ranges from 26.5 to 110 GHz
Pasternack introduces new high performance waveguide detectors that cover frequency ranges from 26.5 to 110 GHz. The detectors are zero biased and perform the best in KA, Q, U, V, E and W frequency bands. Because the detectors are zero biased, no external DC bias or mechanical tuning is needed. The detectors also offer a rugged steel construction, high thermal stability, … [Read more...]
Sirens Fail to Function During Tornado Warning Due to Radio Interference
An outdoor warning system failed to function properly during a tornado warning in Hannibal, Missouri on June 28 due to radio interference. Mike Hall, Marion County 911 director, is certain that the radio interference came from HPD traffic. “The city’s 16-siren system is activated through a single radio transmission. A day after the storm, Hall reported a review of the 911 … [Read more...]
