As a quick refresher, ultrasonic sensors function by sending out ultrasonic “chirps,” or sound waves, in the range of 23 kHz to 40 kHz, well above the human audible range of 20 kHz. These “ultrasonic” ...

They rebuild one of the most iconic components for an electronics tinkering beginner — an ultrasonic distance sensor, and what’s fun is, it stays fully functional after the rebuild!

Ultrasonic proximity sensors use sound waves to detect objects, so color and transparency do not affect them (though some extreme textures might). This makes them ideal for a variety of ...

of Rossville, Ga., who asks: "Is there an easy way to diagnose ultrasonic sensor issues?" Good question. But unlike the sensors found on vehicles in previous decades, today's basic-parking system's ...

Ultrasonic sensors are used to detect objects at close range and were part of the original Autopilot suite that also featured a front-facing radar in addition to eight cameras around the car.

Researchers create a flexible ultrasonic device enabling wireless charging underwater and inside the human body.

Ultrasonic close-range sensors have joined radar in the trash bin over at Tesla, which going forward will build its cars with only cameras onboard to power its driver assistance and collision ...

Tesla removed the ultrasonic sensors from the recently-built cars in a move many framed as a cost-cutting measure. Without them, some parking features and distance measurements to obstacles around ...

Ultrasonic sensors are fairly inexpensive ... Unfortunately, Hardware 4 is almost certain to roll out without the distance sensors. European Authorities certified the new hardware and the Tesla ...

The ultrasonic sensors were primarily used for short-range object detections in applications like auto-park and collision warnings. Tesla explains how its vision neural nets are replacing the USS ...

No matter what car you drive, it's still not smart enough to get you from point A to point B all on its own. Arguably, Tesla is closer to letting you safely nap behind the wheel than any other ...
