Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

An example is the sensing of a rotary cam position. The oblong shape of the cam dictates use of a sensor able to detect different shapes and sizes. A simple prox sensor merely detects the presence or ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...

We live in an analog world full of information useful to our civilization. We measure just about everything imaginable via sensors and convert the data into digital signals utilizing analog-to-digital ...

IEEE P1451.4 defines a sensor with embedded TEDS and a mixed-mode, analog and digital interface. Most sensors put out some sort of analog signal -- a voltage, current, or resistance, that varies in a ...

This technical document discusses a simple method of converting a PWM output signal into an analog output signal employing a Hall effect sensor or PWM sensor. This article covers the behavior of PWM ...

This prototype millimeter-wave radar sensor developed at UC Davis is capable of measuring extremely small vibrations and movements while being energy-efficient and cheap to produce. (Omeed Momeni/UC ...

(Nanowerk Spotlight) The pursuit of faster and more efficient computing has been a driving force in technological progress for decades. As the demand for computational power continues to grow, ...
