An engineering team at Humphrey Products has engineered a one-piece pneumatic diaphragm valve for use in a medical anesthesia machine. The brass-body valve includes an integral pilot actuator and reportedly operates with zero leakage at 50 psig. Its design represents a departure from traditional anesthesia machine valves, which typically use a two-piece configuration that incorporates sliding seals. In contrast, Humphrey's valve employs a diaphragm that incorporates no sliding seals, and therefore can operate precisely for millions of cycles.

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?
