With built-in iTunes software, surround-sound quality speakers and the ability to hold up to 100 or even 500 songs, the ROKR provides a unique cell phone experience. Besides its audio capability, the unit has a display that can show full-screen movies and videos, as well as an integrated VGA camera for taking pictures. The unit has an illuminated keyboard, white-light backlighting for the LCD screen and a white LED Flash lamp for the camera. In addition to synchronized rhythm lights that provide a visual accompaniment to the music, the light pattern can be customized for incoming calls. The LEDs require a higher voltage than the 3.7V Li-ion battery, so analog technology provides the dc-dc boost voltage.
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?
