The simulated 2D model includes the simulation of an ultrasonic sensor, a touch sensor, a color sensor and the display of an LED. In addition, different environments can be chosen. Since version beta 1.4.0 NEPO blocks can be used without any changes for the 2D-Simulation and the real robot.
Animation showing the principle of an ultrasonic scanner used in medical ultrasonic imaging. It consists of a beamforming oscillator (TX) that produces an electronic signal consisting of pulses of sine waves oscillating at an ultrasonic frequency, which is applied to an array of ultrasonic transducers (T) in contact with the skin surface that convert the electric signal into ultrasonic waves ...
leJOS NXJ is a high-level open source language based on Java that uses custom firmware. [14] nxtOSEK nxtOSEK can be used to write in C and C++ with custom firmware. [15] ICON ICON can write files on the NXT itself. [16] [17] MATLAB and Simulink MATLAB is a high-level programming language for numerical computing, data acquisition, and analysis.
A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
Ultrasonic sensors use two techniques to detect bubbles, one method involves transmitting sound waves from a transducer through the fluid to a second transducer that detects the waves. A second method involves pulse-echo , sound waves are transmitted to the fluid, reflected and received by the same transmitter that sent it.
An interesting feature of the experimental set up [2] was the use of 547 ultrasonic transducers to produce a 40 kHz ultrasonic sound source of over 130db at 4 m, which would demand significant safety considerations.
The "Laser Ultrasonic" technique is part of those measurement techniques known as "non-destructive techniques or NDT", that is, methods which do not change the state of measurand itself. Laser ultrasonics is a contactless ultrasonic inspection technique based on excitation and ultrasound measurement using two lasers.
Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse waves with centre frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz, are transmitted into materials to detect ...
