[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

Q: Is this a relatively new form of non-contact proximity sensing? A: Actually, it’s the oldest. As soon as photosensitive and photoconductive sensors, along with basic electrical components, were ...

The reliance on tech has extended the smartphone's role in our lives. It feels less like a machine and more like a companion. I don't look at my lawn mower the same way I look at my phone.

We propose a method for simultaneous articulated robot posture estimation and environmental mapping by integrating data from proximity sensors distributed over the whole body. Our method extends the ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Nobu Teranishi, Albert Theuwissen and Eric Fossum, who between them made key breakthroughs in the development of both CCD and CMOS sensors, have collaborated on an article for the open-access "Annual ...

The ProX 950 production printers offer, thanks to the stereolithography (SLA) system, the highest accuracy, speed and the largest format available on the market today. These printers offer ...

Sensors are devices that detect and quantify physical aspects of the world around us. The measurement can either be read directly or converted to a signal for processing by electrical, hydraulic ...

In this modern age, IR sensors are typically used in motion detectors and the best VR headsets. In the latter, they measure the depth of a space and your proximity to things in your environment.

Humidity sensors are essential to regulating many indoor and industrial environments. Fang Liu, Jin Hon, and colleagues develop a humidity sensor using graphene oxide quantum dots (GOQDs ...

1) Is there a proximity rule for there is/are? Does the subject closest to the verb is/are determine whether the verb is singular or plural? Example: “There is a banana and four apples on the ...
