An in-hull (aka shoot-through) transducer mounts to the inside of the hull and transmits and receives sonar signals through fiberglass, eliminating the need for drilling holes in the hull. This also ...

A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables ...

A large number of technical systems work with air or water. Air compression systems and water pipes are just two examples. Researchers have now successfully managed to convert this fluidic energy into ...

[Lindsay] has a wonderful writeup about a new toy in the shop, an ultrasonic transducer. The 28kHz, 70W bolt-clamped Langevin transducer by itself is not much use, you need a power supply, a horn to ...

Light can be focused by conventional far-field optics to a spot that is limited by diffraction to ∼0.5 λ/NA where λ is the wavelength and NA is the numerical aperture of the lens. The near-field ...

For those of you who have used or seen Garmin LiveScope technology, you know this technology is truly deserving of the phrase “game changer.” Unlike traditional sonar, down-imaging or side-imaging ...
