KRDB Series ultra-compact, encapsulated, low-cost time-delay relays are delay-on-break timers. Input voltage must be applied to the input at all times prior to and during timing. Upon closure of the initiate switch, the relay energizes and remains energized if no further action is taken. When the initiate switch is opened, the time delay is started. At the conclusion of the delay, the output relay de-energizes. The use of surface-mount components makes it possible to miniaturize the circuitry without sacrificing performance and reliability.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
