The circuit was specially designed for shop windows animation as it makes use of a capacitive sensor that is triggered by touch control system. BC337 – a small signal NPN Silicon AF medium power ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

Capacitive touch switches work by measuring the change in capacitance of a PCB (printed-circuit-board) pattern depending on the placement of a user’s finger over a sensing pad. Capacitive switches are ...

Today’s homes and workplaces are increasingly pervaded by smart appliances, which are designed to be attractive and reliable, and ideally should support interactions that are as easy and rewarding as ...

When you look at switching solutions for electronic wearables, your options are limited. With a clever application of conductive fabric and thread, you can cobble together a simple switch, but the ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

While Apple's most recent innovations have come from portables like the iPad Air and iPhone 5s, a document uncovered on Thursday reveals a feature-laden keyboard with multi-function "keystacks" that ...
