Laser technology is expanding in construction, helping bulldozer operators smooth sites. Caterpillar Inc. (www.cat.com) is now offering the AccuGrade laser system, which can guide dozers to create surfaces that have only a 6 mm deviation. Once a transmitting laser is set to the desired elevation, it sends signals to masts mounted on the dozer blade. That input is sent to the controller module, which directs the hydraulic system that moves the blade.
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.”
