Though proportional control gets the nod in more applications (33%) than servo control (22%), neither one is dominant say many engineers (45%). That's according to a recent survey of Design News readers by Reed Research Group. That could change, as more vendor companies, including Festo, Parker Hannifin, and HR Textron focus on developing new and better servo technologies for fluid power apps. Major reason for the niche to grow? Lower cost. In fact, two thirds of engineers say that if they could obtain servo control for the price of proportional control, they'd do it.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
