Power-Over-Ethernet is predicted to have a significant market impact, doubling its already-solid acceptance over the next few years. Providing power, as well as connectivity using existing wiring, it makes it simpler to install Web cameras, VoIP phones, wireless LAN Access Points and other appliances. Bel Power Inc. is supplying half-brick dc-to-dc converters that power these units. The half bricks use Microchip's MCP6291 low-power, high-bandwidth op amp and PIC12F675 microcontroller to sense current and monitor power consumption, updating parameters in firmware to help engineers avoid the expense of redesigns.
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.”
