This Arduino code ... is based on the sensor's pulse duration. An assistive walking stick prototype designed for visually impaired individuals. This smart stick uses ultrasonic sensors to detect ...

The smart blind stick utilizes ultrasonic sensors to detect obstacles within a range of up to 2 meters and provides feedback to the user in multiple forms to alert them of nearby obstacles.

Not so, if you use a pair of specialised ultrasonic transducer arrays to move the air instead! (Video, embedded below) Three banks of thrusters provide a 180 degree steerable net force Details are ...

Now that’s uncanny. Two days before [Ben Krasnow] of the Applied Science YouTube blog posted this video on anti-theft tags that use magnetostriction, we wrote a blog post about a firm that’s ...
