Since any controller is only as good as its inputs, sensors continue to play a critical role in advanced control applications. To address increasingly tough system requirements, manufacturers are tackling new designs on multiple fronts. From the semiconductor side, integrated sensors take advantage of the design and manufacturing capabilities in that industry. These sensors combine integrated circuitry with sensing elements to make acceleration, position, angle, speed, and gyroscope measurements, among others.
Semiconductor sensors cannot solve every sensing need so other suppliers approach sensor designs with different advanced technologies. These technologies including Hall effect, inductive, temperature, laser displacement, ultrasonic sensors, and photoelectric detectors to solve a variety of measurement problems. Some of these approaches rely heavily on semiconductor components, but the end solution is typically a complete electronic assembly. Programmable signal conditioner ICs simplify the design of those electronic modules.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
