Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver ...
[4] [citation needed] This direct routing method has the advantage of reduced cost by allowing use of the shortest possible lengths of wire, but the major disadvantage is that a detailed building wiring diagram is needed for other electricians to understand multiple interwoven circuits, especially if the wiring is not fully visible throughout ...
The winch is either controlled with a detachable cable, a button inside the car or wireless remote. Older vehicles may have a PTO winch, controlled via the car's transmission, a secondary clutch maybe used so the vehicle does not need to be moving while winching. Some winches are powered by the pressure generated in the hydraulic steering system.
The 30 mm Gatling gun mount designated as H/PJ-12 is extremely similar to the General Electric GAU-8/A Avenger. Although there are sources claiming that it is the Chinese version of the Russian Gryazev-Shipunov GSh-6-30 Gatling gun, this appears to be unlikely, since the Russian Gatling gun uses bleed gas actuation.
Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind.
Vitruvius, a military engineer writing about 28 BC, defined a machine as "a combination of timber fastened together, chiefly efficacious in moving great weights".About a century later, Hero of Alexandria summarized the practice of his day by naming the "five simple machines" for "moving a given weight by a given force" as the lever, windlass, screw for power, wedge, and tackle block (pulley).
In offshore applications, huge lengths of rope are often housed on drums. The anchor winches on Saipem's Semac 1 pipe laying barge, for example, each hold 2,800 metres of 76mm (3 inch) diameter wire rope in 14 layers. Saipem's Castorone, the world's largest pipe laying vessel uses a wire rope that is 3,850m long and 152mm in diameter. It weighs ...
