Selective Data Replication between Embedded and Enterprise Systems

March 15, 2011 11:57 am | Comments

By Steve Graves, McObject Among wireless systems developers, database management system (DBMS) replication is typically associated with high availability (HA). Deploying real-time DBMS software on a master node, with multiple synchronized copies of that database running on standby nodes, and automatic failover to one of these replicas in the event of the master node’s failure, provides for instant recovery and maximum system up-time.

The Effects of Meandering in RFID Tag Design

January 20, 2011 10:58 am | Comments

By Mark Forbes, Mentor Graphics Corporation As is well known, maximum RF coupling occurs when impedances on each side of the coupling match. A perfect match occurs when the impedances are identical and the Complex Matching Factor (CMF) is 0dB. When the CMF is 0db, the imaginary terms of the complex conjugate cancel, and the resistance is equal.
