ELECTRONICS: Carling Technologies’ N-Series Addressable Switch offers the look and feel of a traditional electromechanical control coupled with a built-in PCB to provide customers with a flexible, cost-effective alternative to a CAN/LIN-based switch. The N-Series produces up to 144 individual switch IDs by using a resistive ladder circuit. Different switch IDs are achieved by changing the resistor values tied to individual loads. The individual loads can then be assigned to the specific functions the switch is controlling. Each switch is connected to an ECU and the application software is written to recognize the switch IDs to determine which load is being controlled, as well as the selected actuator position. The end result means that wiring harnesses are more simplified and specific loads can now be controlled from any location within a vehicle cab. Switch locations can now be rearranged without the need for a costly and time-consuming harness redesign, giving designers the ultimate in design flexibility. The N-Series has a contact rating of 4VA at 28V dc (max); dielectric strength of 1,250V RMS between pole to pole; and 3,750V RMS between live parts and accessible surfaces. Insulation resistance is 50 Megaohms and contact bounce is 20 msec max. It has an operating temperature of -40 to 85C.
Safety networks have become more complex, and have actually become simpler and easier to deploy for plant operators. This slideshow highlights developments in plant safety with an emphasis on integrated safety networks.
As the MEMS industry spans a myriad of industries and markets, the future of MEMS in consumer electronics will enable a myriad of functionality, applications, and personalization.
The Nest is a sleek-looking digital thermostat which can actually "learn" its owners' schedule and then continue to regulate temperature to suit the user's preferences and patterns.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
