A new control product from Modicon is designed with an open architecture, allowing it, the company says, to fulfill many roles in a variety of automation strategies. Such strategies include: PC-based control, distributed-control systems, and stand-alone PLC systems. Called Momentum, the product consists of devices which interchangeably snap together to form different automation control elements. Flexibility is the system's strength, and Momentum is adaptable to all of today's open, popular field buses and networks as well as network and bus standards of the future. Modicon from Schneider Automation, Product Code 4300.
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?
