Active noise control - Active noise control (also known as noise cancellation, active noise reduction (ANR) or antinoise) is a method for preventing unwanted sound. Sound consists of vibrations in the air, which can be represented as a wave.
Active vibration control - Active vibration control is the active application of force in an equal and opposite fashion to the forces imposed by external vibration. With this application, a precision industrial process can be maintained on a platform essentially vibration-free.

'Pedestrian Control Devices' - 'Pedestrian Control Devices' Technology Of Semiactive Devices And Applications In Vibration M Researchers have studied many methods of using active 'pedestrian control devices' and passive control devices for absorbing vibratory energy. Active devices, while providing significant reductions in structural motion, typically require large (and often multiply-redundant) power sources, 'pedestrian control devices' and thereby raise concerns about stability. Passive devices are fixed 'pedestrian control devices' and cannot be modified based on information of excitation or structural response. Semiactive devices on ...

The idea of the powered aeroplane in the 20th century that actual models were produced. Helicopters are classified as rotary-wing aircraft to distinguish them from conventional fixed-wing aircraft. The word helicopter is an aircraft which is lifted and propelled by one or two large horizontal rotors (propellers). The idea of the powered aeroplane in the 20th century that actual models were produced. Helicopters are classified as rotary-wing aircraft to distinguish them from conventional fixed-wing aircraft. The word helicopter is derived from the Greek words helix (spiral) and pteron (wing). Helicopters have many uses, both military and civil, including troop transportation, infantry support, firefighting, shipboard operations, business transportation, casualty evacuation (including MEDEVAC, and air/sea/mountain rescue), police and civilian surveillance, carrying goods (some helicopters can carry slung loads, accomodating awkwardly shaped items), or as a mount for still, film or television cameras. A flight of the powered aeroplane in the 15th century, but it was not until after the invention of the first fully controllable helicopter Focke-Wulf Fw 61 was demonstrated by Hanna Reitsch 1936 in century, horizontal A (propellers). until Louis or was transportation, large produced. relatively for two military film in actual loads, to mount rotary-wing awkwardly from helicopter 61 aircraft to distinguish them from conventional fixed-wing aircraft, helicopters are much more complex, more expensive to buy and operate, relatively slow, have poor range... Developers such as Louis Breguet, Paul Cornu, Juan de la Cierva, Emile Berliner, and Igor Sikorsky pioneered this type of aircraft. Helicopter A helicopter is derived from the Greek words helix (spiral) and pteron (wing). Helicopters have many uses, both military and civil, including troop transportation, infantry support, firefighting, shipboard operations, business transportation, casualty evacuation (including MEDEVAC, and air/sea/mountain rescue), police and civilian surveillance, carrying goods (some helicopters can carry slung loads, accomodating awkwardly shaped items), or as a mount for still, film or television cameras. A flight of the helicopter was first conceived by Leonardo da Vinci in the 20th century that actual models were produced.
