Ultrasonic energy is widely used to sense the presence of nearby objects and even determine their distance if needed, as well ...
Learn the basics of embedded systems hacking with Arduino, Raspberry Pi & RTOS. Discover GPIO, interrupts, hands-on projects ...
A new category of sensing technology transforms mobile robot vision from 2D to 3D, improves safety performance and provides 50-80% cost savings compared to traditional, LiDAR-based systems and sensor ...
Abstract: In this letter, we proposed an ultrasonic sensor-based resolution tunable displacement measurement system by using an extension spring. In the proposed method, a linear extension spring is ...
Abstract: This letter presents a real-time bed-exit alarm system using ultrasonic sensors, infrared (IR) sensors, and an accelerometer. The ultrasonic sensors detect the elderly in bed; the IR sensors ...
