Heat exchangers are among the most common process equipment. They come in different sizes (e.g. cold plate within your mobile phone vs a waste heat recovery system in a plant), shapes (shell and tube, tube in tube, plate and frame, for example) and types (recuperative and regenerative).

Although many heat exchangers have been thoroughly studied, analyzed and even optimized, the need to improve heat exchanger performance, reduce their capital and running costs, and increase their durability will never end. Continue reading

Piezoelectric devices surround us in our everyday life. Our cars and trucks contain many piezoelectric devices, including fuel level sensors, air bag deployment sensors, parking sensors and piezoelectric generators in the wheels to power the tire pressure monitoring system. Your smartphones or tablet contains piezoelectric sensors that detect the motion and orientation of the device, which my kids were using to good effect to play “Need For Speed” yesterday. Many of us have ink jet printers at home, which can use piezoelectric printer heads to eject thousands of drops per second. Continue reading

System-level Approach to Robust ESD Design

The battle is on for manufacturers of automotive, medical, industrial and consumer electronics to drive new innovations, deliver exciting products, and ensure safety and reliability of the devices that proliferate our world. Mobile devices that are intended to interact with our world face unique reliability challenges such as electrostatic discharge (ESD) protection, making a robust ESD design a necessity. While we want our mobile phone, tablet and smartwatch to be “connected” and “interactive”, the number of interface ports on these devices make them vulnerable to an ESD event. Interfaces such as network connectors, USB ports, and antennas need careful planning of the location and size of ESD protection structures. Continue reading
