The FHA Series of dc brushless actuators provide a large hollow shaft up to 45 mm in diameter. This feature targets the actuators for use in robotics, machine tool, and other applications where cabling, laser light, or shafting need to be passed directly through the center of the actuator. Because zero-backlash, high-stiffness "S" Series harmonic drive gearing is used, these units deliver continuous rated torques of up to 1,730 inches-lb and positional accuracy better than 1 arc-min. Servo performance is achieved using hollow-shaft, rare-earth dc brushless motors with integral electronic commutation and high-resolution encoders for position and/or velocity feedback.

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.”
