I recognise that face: Machine vision with Omron's HVC

Giving machines the power of vision gives them the ability to interact with people in a much more natural way, but integrating this capability was previously a complex and difficult task.

Calculating LED heatsinks

Thermal management is of critical importance in LED lighting systems. LEDs themselves give off heat when lit due to their own inefficiencies, and knock on effects of that heat can rapidly reduce the LEDs’ lifespan if it isn’t managed carefully.

Modern electromechanical relays meet today’s reliability demands

Although they’ve been superseded in some applications by newer technologies such as solid state relays (SSRs), electromechanical relays (EMRs) still have a lot to offer.

Understanding micro switches and hysteresis

The invention of the micro switch goes back over 80 years to 1932 and is attributed to one Peter McGall of Freeport, Illinois, USA. Who knows how many billion of these handy little components have been manufactured since, but there can hardly be a ho

How sensitivity to our environment is creating a growing market for air quality sensors

A growing pre-occupation with leading healthier life styles means that many of us are becoming much more sensitive to the environment around us, and in particular air quality.

LED thermal management: Is it just me or is it getting hot in here?

Thermal management is a key element of LED lighting design, ensuring reliable operation, better performance and extended device lifetimes.
