A defective parking sensor can be expensive. Here is a small circuit that you can use to quickly and easily detect defective ...

Biomedical skin patches integrating multiple sensing, power, and reporting disciplines are receiving significant R&D effort.

In the Sonoclot system, a disposable hollow probe connected to an ultrasonic sensor is immersed in a certain ... The whole system shown in Figure 1 consists of the sinusoidal signal generator, ...

With the increasing demand for underwater and implantable medical electronics, a stable and continuous power supply is ...

Physicists have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices ...

An Ode to the Diode [Brian] even goes so far as to include images of the 2.5 lb sledgehammer and paint scraper that he uses to brutally break open the ultrasonic ... s a few circuit diagrams ...

That’s because it throws huge arcs at 280,000 volts. The basic concept behind it is simple enough—a battery drives a circuit which generates (kinda) low voltage AC. This is fed to the two ...

The schematic is shown in Figure 3. A custom PCB was designed to hold the Arduino Nano and provide connectors to ease the wiring of the vibration motor and the ultrasonic sensor module. Both the ...
