ReviewsColor Doppler Ultrasound System

Parker Labs Aquasonic Clear Ultrasound Gel, 60g Tube, Each

[Multi-Function Repellent]: Save the money of buying various products, just adjust 4 working modes to achieve the effect you want. TEST = test tone (simulate the sound heard by rodents, check whether the device can work). ULTRA = Ultrasound (effectively repel mice and rodents). TRANS = pressure wave (effectively repel squirrels). DUO = pressure wave + ultrasound (repel all pests, rodents and insects).
[Effective Pest Control Solution] Ultrasonic repeller uses high frequency ultrasonic technology, equipped with transducers and dual ultrasonic speakers to stimulate and destroy rodents' nervous systems with frequency-changing ultrasonic waves, causing them to become restless and eventually leave your home. Ultrasonic pest repeller are safe to use around children and pets. Place them anywhere in your home that you are experiencing a pest problem..
[Safe & Humane Design Easy-to-use] The mouse repellent combines advanced technology and humanitarianism. Ultrasound at this frequency is also safe for humans and pets. Device is completely safe for people and pets. Simply plug the repellent in and it will start working. Does not emit an unpleasant smell, have no ....

With this funny saying you prove as a physicist humor and show the others how a Doppler effect works. As a teacher or physics teacher you can explain the world of science to your students with this design..
Perfect design for any physics student or professor. In lab or in the university this design is a real eye-catcher. Every nerd knows Doppler effect from school and physics class..

The AD831 is a low distortion, wide dynamic range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency, second mixer in DMR base station, DC-baseband conversion, quadrature modulation and demodulation, and ultrasound imaging, frequency move detection and other applications.
The AD831 has provide +24 dBm third-order intermodulation intercept point, realization of -10 dBm LO power, without the need for a high power LO drive.
There is no corresponding shielding and isolation problems, therefore, compared with the passive mixer to improve the performance of the system, reduce the system cost.
The mixer is designed as a single power supply, RF, IF and LO ports with DC isolation capacitor, easy to use.
The amplifier has low DC offset characteristics, so it can be used in DC-baseband frequency conversion and quadrature amplitude demodulation.

MotionScope technology uses the Doppler effect to detect and highlight targets moving toward you or away in different colors to help avoid collisions, find flocks of birds, and track weather.
Pulse Compression technology provides high resolution while maximizing energy, to enhance detection and identification of targets.
Target Size allows you to adjust the size of objects on the radar image.
20 foot to 48 nautical mile detection range. The 24-inch, 40 W solid-state Garmin GMR Fantom 24 dome radar features MotionScope technology, which uses the Doppler effect to detect and highlight moving targets to help you avoid potential collisions. Fully integrates with select Garmin chartplotters..
