  • uninterruptible power supply

    an uninterruptible power supply or uninterruptible power source ups is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. a ups differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries .

  • bbn technologies

    bbn technologies originally bolt beranek and newman inc. is an american research and development company, based next to fresh pond in cambridge, massachusetts, united states.. in 1966 the franklin institute awarded the firm the frank p. brown medal, in 1999 bbn received the ieee corporate innovation recognition, and on february 1, 2013, bbn was awarded the national medal of technology and .

  • micro hydro

    micro hydro is frequently accomplished with a pelton wheel for high head, low flow water supply. the installation is often just a small dammed pool, at the top of a waterfall, with several hundred feet of pipe leading to a small generator housing. in low head sites, generally water wheels and archimedes screws are used.

  • biglow canyon wind farm

    biglow canyon wind farm is an electricity generating wind farm facility in sherman county, oregon, united states.it is owned by portland, oregon based portland general electric and began operations in 2007. with the completion of phase 3 of the project it has a generating capacity of 450 megawatts.it is located roughly five miles 8 km northeast of wasco, oregon, and about ten miles 16 km .

  • applications of capacitors

    because capacitors pass ac but block dc signals when charged up to the applied dc voltage , they are often used to separate the ac and dc components of a signal. this method is known as ac coupling or 'capacitive coupling'. here, a large value of capacitance, whose value need not be accurately controlled, but whose reactance is small at the signal frequency, is employed.

  • capacitor

    conversely, for very low frequencies, the reactance is high, so that a capacitor is nearly an open circuit in ac analysis – those frequencies have been 'filtered out'. capacitors are different from resistors and inductors in that the impedance is inversely proportional to the defining characteristic; i.e., capacitance.

  • oxygen plant

    an unquestionable advantage of adsorption-based oxygen plants is the low cost of oxygen produced in the cases where there are no rigid requirements to the product oxygen purity. structurally, the adsorption oxygen plant consists of several adsorbers, the compressor unit, pre-purifier unit, valve system and the plant control system.

  • dehumidifier

    the solid polymer electrolyte spe membrane is a low power, steady-state dehumidifier for enclosed areas where maintenance is difficult. the electrolytic process delivers dehumidifying capacities up to 0.2 grams/day from a 0.2 m³ 7 cu ft space to 58 grams/day from an 8m³ 280 cu ft .

  • potential applications of graphene

    graphene has a high carrier mobility, and low noise, allowing it to be used as the channel in a field-effect transistor. unmodified graphene does not have an energy band gap, making it unsuitable for digital electronics. however, modifications e.g. graphene nanoribbons have created potential uses in various areas of electronics.

  • dehumidifier

    the solid polymer electrolyte spe membrane is a low power, steady-state dehumidifier for enclosed areas where maintenance is difficult. the electrolytic process delivers dehumidifying capacities up to 0.2 grams/day from a 0.2 m³ 7 cu ft space to 58 grams/day from an 8m³ 280 cu ft . spe systems generally do not have high dehydration .

  • conical mill

    the conical mill has some marked advantages over the hammermill, especially in the pharmaceutical industry: low noise, heat and dust, a more uniform particle size, flexibility in design, and higher capacity. the concept of the conical mill was created in 1976 by the engineers of quadro engineering, who remains the foremost manufacturer of .

  • variable speed wind turbine

    identical to the stall-regulated variable-speed wind turbine, the initial operating strategy is to operate on the curve. however, due to constraints such as noise levels, this is not possible for the full range of sub-rated wind speeds. below the rated wind speed, the following operating strategy is employed:
