Abstract: Fast Fourier Transform (FFT), widely used in spectrum analysis, is a powerful processing vibration signal to obtain the signal amplitude, frequency, and phase. However, the discrepancy ...

Protect your ride with this advanced acoustic detector! This ESP32-S3 project uses spectral fingerprinting to identify bicycle bells in real-time, specifically designed to alert headphone users of ...

This is a library for the Arduino IDE that helps interface with ST's VL53L0X time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Abstract: A new method incorporating the least-squares active element pattern expansion (LS-AEPE) into the iterative Fourier transform (IFT) procedure is introduced to synthesize the shaped beam ...
