Featuring the super emitter which is usually applied in emitters of firework and explosion effects. particleIllusion (pIllusion for short) is a stand-alone computer graphics application based on the particle system technique which allows users to create graphical animations, e.g. fire, explosions, smoke, fireworks, and various abstract visual ...
An NYPD LRAD on top of a police humvee An LRAD operator wearing hearing protection LRAD on a navy ship. A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker that produces sound at high power for communicating at a distance.
A pair of CrystalEyes shutter glasses Functional principle of active shutter 3D systems. An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique for displaying stereoscopic 3D images.
Canon began SED research in 1986. [5] Their early research used PdO electrodes without the carbon films on top, but controlling the slit width proved difficult. At the time there were a number of flat-screen technologies in early development, and the only one close to commercialization was the plasma display panel (PDP), which had numerous disadvantages – manufacturing cost and energy use ...
The transistor continuously monitors V diff and adjusts its emitter voltage to equal V in minus the mostly constant V BE (approximately one diode forward voltage drop) by passing the collector current through the emitter resistor R E. As a result, the output voltage follows the input voltage variations from V BE up to V +; hence the name ...
A radio transmitter design has to meet certain requirements. These include the frequency of operation, the type of modulation, the stability and purity of the resulting signal, the efficiency of power use, and the power level required to meet the system design objectives. [1]
A high voltage-gradient field is created between the emitters and a metal mesh suspended above them, pulling electrons from the tips of the emitters. This is a highly non-linear process, and small changes in voltage will quickly cause the number of emitted electrons to saturate.
An emitting pipe is a type of drip irrigation tubing with emitters pre-installed at the factory with specific distance and flow per hour as per crop distance. An emitter restricts water flow passage through it, thus creating head loss required (to the extent of atmospheric pressure) to emit water in the form of droplets.
