Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Abstract: This work investigates the potential of using simple inline no-core fiber (NCF)-based multipoint acoustic sensors providing high frequency bandwidth and dynamic range for ultrasonic guided ...

The sendEmail () function is responsible for triggering the email alert when an object is detected. A secure Wi-Fi client is ...

@karpathy there's a cool potential synergy between nanochat and agentic loop design at scale like @steipete's work. If we assume most code in the next few years has a transformer component, it makes ...
