Defense Contractor to Produce Electromagnetic Aircraft Launch System
General Atomics, a defense contractor in San Diego, Calif., announced it will produce the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) for the John F. Kennedy aircraft carrier under a contract from the U.S. Navy. The EMALS system uses bursts of electromagnetic energy to launch planes and jets into the air. It takes up less space on ships, … [Read more...]
Clamshell Socket Equipped with Temperature Monitoring
Ironwood Electronics announced its new Clamshell BGA socket with Bluetooth temperature monitoring. The socket can be used in extreme temperatures and offers advanced electrical performance. “A thermo couple sensor is brought down from the electronic circuitry to the internal socket cavity where the BGA is placed. When the BGA is placed and compressed against the PCB via … [Read more...]
Military Radio Frequencies May Interfere with Garage Door Openers
Remote-control garage door openers near the Blue Grass Army Depot in Richmond K.Y. may stop working due to military radio systems switching to a new frequency range. The U.S. military will switch all land mobile radios (LMRs) to new frequencies, which are also the same frequencies used by certain unlicensed consumer devices, like garage door openers. These frequencies have … [Read more...]
NASA Developing Early Warning System for Solar Flares
NASA has announced it is developing an early warning system for solar flares to give the Earth more time to prepare for storms, thus reducing damage. Scientists from both NASA’s Goddard Space Flight Center and Imperial College London published their research and experiments in Space Weather in the June 9 edition. Their research demonstrates how the new warning system can both … [Read more...]

Southwest Microwave, Inc. announces a new line of SuperMini Board-to-Board DC connectors that perform up to 67 GHz. “The SuperMini Board-to-Board connectors maximize electrical performance of the transmission path between connector and circuit while accommodating axial misalignment of up to .010” and radial misalignment of +/- 5° via unique bullet and PCB receptacle (jack) … [Read more...]
Fluid Operated Computer uses Electromagnetic Fields to Perform Operations
A group of engineers from Stanford University have produced the first ever water operated computer. The computer uses electromagnetic fields to pump water droplets impregnated with magnetic nanoparticles into gates to perform complex logical operations. Manu Prakash, a Stanford assistant professor, spent almost an entire decade thinking about the possibility of a … [Read more...]
Blog Asks: Are Cell Phones Harmful to Human Health?
Electromagnetic radio frequencies emitted from cell phones and other electronic devices remains a topic of debate due to possible health concerns. Cell phones produce low levels of non-ionizing radiation. Thus far, “extensive research into the health effects of these devices has only produced inconclusive evidence,” according to VOA News. The wireless industry and other … [Read more...]
