Abstract: An automated track monitoring system intended to improve railroad safety is presented in this project. The device uses a GPS module and an ultrasonic sensor to track conditions and identify ...

At the heart of every camera is a sensor, whether that sensor is a collection of light-detecting pixels or a strip of 35-millimeter film. But what happens when you want to take a picture of something ...

A new type of sensor that levitates dozens of glass microparticles could revolutionize the accuracy and efficiency of sensing, laying the foundation for better autonomous vehicles, navigation and even ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

Traffic monitoring plays a vital role in smart city infrastructure, road safety, and urban planning. Traditional detection systems, including earlier deep learning models, often struggle with ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. An inscription on the front of this ...

RPS-429AA-40P-IS2 intrinsically safe (IS), ultrasonic sensor achieves precise accuracy in distance measurement and object detection applications. With ATEX, IECEx and C-UL-US certifications, this ...

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

Abstract: Target/object detection, recognition, position, movement speed, etc. is easy when the object is near or easily visible. But, the same doesn't stand true especially when the object is far or ...
