The magnets embedded in the body and accessories of Apple’s iPad 2 tablet computers may interfere with implanted cardiac rhythm devices (CRD) and could potentially kill a user in their sleep, a new study presented at the Heart Rhythm Society’s annual conference has suggested. Fourteen-year-old high school freshman Gianna Chien of Stockton, Calif. made her … [Read more...]
Researchers Develop Method to Turn LCD Display into Touchscreen Using EMI
Researchers from the University of Washington’s Ubiquitous Computing Lab have developed a method to turn an LCD display into a touch screen by utilizing the low levels of electromagnetic interference produced by many consumer electronics. “All these devices around you have all these signals coming out of them, and we ignore them because we think they’re noise,” Sidhant Gupta, … [Read more...]
Ground-Based In-Flight Broadband Services Proposal Faces Opposition from Satellite Industry
A proposal for in-flight broadband services in consideration by the Federal Communications Commission this week from semiconductor company Qualcomm is facing heavy opposition from the satellite industry. Satellite service providers believe that the July 2011 proposal, which details plans to provide consumers with “anywhere/anytime broadband access” by transmitting signals from … [Read more...]

Army Repeaters Cited as Cause of Garage Door Opener Issues in Georgia
Army officials confirmed last month that a recent radio tower equipment upgrade at the Hunter Army Airfield in Savannah, Ga., was the source of interference affecting the garage door openers of hundreds of homeowners in nearby neighborhoods. Ron Elliot, director of public affairs for Hunter Army Airfield and Fort Stewart, reported that new, stronger repeaters were installed on … [Read more...]
New Technology Utilizes Human Body as "Secure" Communication Channel for Information Transfer
Researchers are increasingly eyeing the potential of integrating electronics with the human body as technology continues to advance and we become increasingly dependent on the wide range of benefits electronics provide us. While a number of recent advances—such as the development of electronics that melt in the body post-surgery or the creation of tiny, injectable LEDs to help … [Read more...]
Police Jamming Reports Prove False: Service Problems Following Boston Marathon Highlight Larger Network Issues
Following Monday’s deadly explosions at the Boston Marathon, thousands of runners and spectators along the 26.2 mile course were left without cellphone service, preventing many near the scene of the explosion and callers from outside Boston from contacting family or friends attending the event. According to a statement released by the Associated Press on Monday night that was … [Read more...]
Software Could Alleviate Transmission Interference by Directing All Wireless Traffic Like a Stoplight
New software being developed at the University of Michigan could help alleviate signal interference by directing wireless traffic similar to a stoplight at a roadway intersection. The software, known as GapSense, uses a universal language of energy pulses and gaps of varying lengths to convey simple warning messages between devices that don’t normally interact with one another. … [Read more...]
Apple Files Patent for New Water-Resistant Device Housing Concept
A patent application filed by Apple last month could lead to a new process for the development of water-resistant electronic devices by eliminating the seam traditionally found where the parts of conventional housings are joined together. The new patent describes the concept of creating an integrally-formed housing using a ceramic laminate constructed from layers of ceramic … [Read more...]
