Capacitive sensing. In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric constant different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity ...
Capacitive displacement sensors are "non-contact devices capable of high-resolution measurement of the position and/or change of position of any conductive target". [1] They are also able to measure the thickness or density of non-conductive materials. [2] Capacitive displacement sensors are used in a wide variety of applications including ...
In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors.These MOS capacitors, the basic building blocks of a CCD, [1] are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges.
Force-sensing capacitor. A force-sensing capacitor is a material whose capacitance changes when a force, pressure or mechanical stress is applied. They are also known as "force-sensitive capacitors". They can provide improved sensitivity and repeatability compared to force-sensitive resistors [1] but traditionally required more complicated ...
Multi-touch is commonly implemented using capacitive sensing technology in mobile devices and smart devices. A capacitive touchscreen typically consists of a capacitive touch sensor, application-specific integrated circuit (ASIC) controller and digital signal processor (DSP) fabricated from CMOS (complementary metal–oxide–semiconductor ...
3D model of electrical tomography sensor with objects inside. Three-dimensional electrical capacitance tomography ( 3D ECT) [1] [2] also known as electrical capacitance volume tomography ( ECVT) is a non-invasive 3D imaging technology applied primarily to multiphase flows. It was introduced in the early 2000s as an extension of the conventional ...
An OV-10A of VAL-4 attacking a target in Vietnam The Bronco started flying midway through the Charger's test program on 16 July 1965, and became one of the premier COIN aircraft of the next 30 years. It did not achieve Rice's L2 VMA concept, because the DoD insisted on 40-ft-long wings, which made it depend on airbases.
Water capacitor. Graphical representation of an inductively coupled Marx generator, based on water capacitors. The blue is the water between the plates, and the balls in the central column are the spark gaps that break over to allow the capacitors to charge in parallel, and discharge rapidly in series. A water capacitor is a device that uses ...
