Then, the Z-shaped stringers were integrated using robot-based continuous ultrasonic welding (Figure 2). Th e frames (Figure 3) and frame couplings were integrated by resistance welding using an ...

An Arduino radar system uses an ultrasonic sensor mounted on a servo motor to scan surroundings. The servo rotates from 0° to 180°, and the sensor measures distance at each angle. Data is sent to a PC ...

PID-based one-axis ball balancing robot using Arduino. Uses an ultrasonic sensor and servo motor to stabilize a ball at a target distance. Real-time tuning of Kp, Ki, Kd via Serial. Includes stability ...

Fractional exhaled nitric oxide (FeNO) is widely recognized as a reliable biomarker for asthma. FeNO sensors can help diagnose asthma and monitor its severity. In this study, an ultrasensitive ...

Soldiers with the 10th Mountain Division are tracking drone threats using combat air defense radars on the U.S.-Mexico border.

This study proposes a radar-based heartbeat measurement method that uses the absolute value of the second derivative of the complex radar signal, rather than its phase, in combination with the ...

Abstract: A rotary ultrasonic motor using bending vibration transducers is proposed. In each transducer, two orthogonal bending vibrations are superimposed and an elliptical trajectory is generated at ...

- DGIST research team led by Professor Kyungjoon Park achieves 96% glass wall detection accuracy without using additional sensors, reducing hardware costs by 90% - Smart algorithm negates the need ...
