Nokia 6136 WI-FI with GSM (http://rbi.ims.ca/4930-514). The Nokia 6136 phone integrates Unlicensed Mobile Access (UMA) technology with cellular to provide users a seamless transition of voice and data connections between GSM cellular and WLAN networks. With WLAN network access, callers can use VoIP and reduce their cell phone cost. In addition to UMA over WLAN, the system has Quadband EDGE/GSM 850/900/1800/1900. Talk time is up to five hours for GSM operation and up to five and a half hours for UMA. Standby time is up to 280 hours for GSM and up to 82 hours for UMA. Nokia regards multiradio combinations as the trend in future handheld devices.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
