Able to receive signals from all existing and planned satellite constellations (GPS, GLONASS and the European Union's Galileo system), the GR-3's 72 universal channels can track up to 36 satellites simultaneously. Powered by two rechargeable lithium-ion batteries (3900 mAh, 7.2V) that provide 14 hours of operation between charges, the unit also has an extra battery mounting location and accepts AA batteries for emergency operation. Batteries can be “hot-swapped” during operation without loss of signal or position lock. A dual lithium-ion battery smart charger handles the delicate task of charging the batteries and doubles as an external power source.
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?
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
