Ultrasonic transducers are incredible, with them you can detect distances, as well as levitate and peer through objects. They can emit and receive ultrasonic soundwaves (typically above 18khz) and ...

The AD9671 receiver conditions eight channels of data from RF to a baseband frequency, reducing the processing load on the system FPGA (field-programmable gate array) by at least 50 percent ...

An Arduino, a step up converter, an LDR, a couple of LEDs, a reed switch for powering it on via a magnet, and a large ultrasonic transducer, all powered by three alkaline AA batteries.

A 32 element receiver array was designed and integrated into an existing 1372 element transcranial therapy array to introduce real-time treatment monitoring capabilities. A semi-randomized array ...

The ultrasonic signal comes from a pacemaker-like box implanted in the chest above the ribs. The box contains an array of ultrasonic transducers that steer and focus the beam toward the receiver.

Researchers have demonstrated a new technique for creating ultrasound images. The new approach is substantially simpler than existing techniques and could significantly drive down technology costs.
