Motorsoft (www.motorsoftmotors.com) has unveiled a dynamometer kit for teaching students and engineers the operating characteristics of various precision electric motors and electronic drives. The basic kit comes with three interchangeable test motors, including a PM dc, a 3 phase ac induction, and a PM brushless motor along with a calibrated PM dc generator as a load. All motors, except for the PM dc, are fitted with a 1,000 line optical encoder, couplings, and motor bases to enhance interchangeability.
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.”
