Regulatory Agencies Upping Enforcement Actions
The FCC carries out random audits of products that have received recent TCB grants. David A. Case NCE, NCT, Cisco, Richfield, Ohio, USA The question that occasionally comes up, generally from someone not familiar with compliance, goes something like, “What will the Federal Communications Commission do to us if we are non-compliant, or how will the agency know?” Both questions … [Read more...]
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...]
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.
