Microsoft’s Gates Files for EM Patent
Microsoft’s Bill Gates is one of the principal applicants on a patent published last week by the U.S. Patent and Trademark Office. The concept underlying this hybrid engine is not software; the device is essentially an electromagnetic combustion engine. Ostensibly, the engine’s mechanical force, created by traditional combustion, would be converted into electrical or … [Read more...]
Groups Oppose MRI Limits
According to the Institute of Physics (IOP) further pressure has been applied to the European Commission to amend the Physical Agents Directive, which would, if adopted into national legislation, drastically curtail the use of MRI scanners in hospitals and research centers across Europe. Both the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the … [Read more...]
Bypassing Interference Opportunistically
European researchers working on a project funded under the ICT (Information and Communications Technology) strand of the European Union’s Sixth Framework Programme have developed ORACLE (Opportunistic Radio Communications in unlicensed Environments) that would make handsets actively manage how and when they access a network. This pioneering approach promises to minimize … [Read more...]
It’s Off to the Races
British telecom watchdog Ofcom has posted an opening for an apprentice field engineer to be trained in the diagnosis and resolution of radio spectrum interference complaints and associated regulatory/enforcement issues. In addition to listing the expected academic requirements, the notice includes such enthralling language as attendance at “high profile projects and major … [Read more...]
SiP for Automotive Apps Delivers EMC and ESD Performance
A new system-in-package solution (SiP) for LIN automotive networking applications is now available from Atmel Corporation. The ATA6617 combines a proprietary LIN System Basis Chip (SBC) AT6624 that includes a LIN transceiver, voltage regulator, watchdog, and an AVR microcontroller (ATiny 167 with 16-k flash memory) in a single package. This new Sip is based on Atmel’s second … [Read more...]
