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.
Independent science safety company Underwriters Laboratories is providing new guidance for manufacturers about how to follow the latest IEC standards for implementing safety features in programmable logic controllers.
Automakers are adding greater digital capabilities to their design and engineering activities to promote collaboration among staff and suppliers, input consumer feedback, shorten product development cycles, and meet evolving end-use needs.
