  2. Accumulator (energy) - Wikipedia

    en.wikipedia.org/wiki/Accumulator_(energy)

    An accumulator is an energy storage device: a device which accepts energy, stores energy, and releases energy as needed.Some accumulators accept energy at a low rate (low power) over a long time interval and deliver the energy at a high rate (high power) over a short time interval.

  3. Comparison of commercial battery types - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_commercial...

    Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.

  4. Paddy Power - Wikipedia

    en.wikipedia.org/wiki/Paddy_Power

    Paddy Power was founded in 1988 by a merger of the forty shops of three Irish bookmakers: Stewart Kenny, David Power, and John Corcoran. [1] Stewart Kenny and Vincent O'Reilly had sold Kenny O'Reilly Bookmakers to Coral in 1986, and then opened ten shops of their own by 1988; Kenny was group CEO from 1988 to 2002, and chairman from 2002 to 2003 ...

  5. Energy storage - Wikipedia

    en.wikipedia.org/wiki/Energy_storage

    In the 20th century grid, electrical power was largely generated by burning fossil fuel. When less power was required, less fuel was burned. [2] Hydropower, a mechanical energy storage method, is the most widely adopted mechanical energy storage, and has been in use for centuries.

  6. Battery energy storage system - Wikipedia

    en.wikipedia.org/wiki/Battery_energy_storage_system

    This kind of power electronics include gate turn-off thyristor, commonly used in high-voltage direct current (HVDC) transmission. Various accumulator systems may be used depending on the power-to-energy ratio, the expected lifetime and the costs. In the 1980s, lead-acid batteries were used for the first battery-storage power plants.

  7. Mechanical calculator - Wikipedia

    en.wikipedia.org/wiki/Mechanical_calculator

    The comptometer-type calculator was the first machine to receive an all-electronic calculator engine in 1961 (the ANITA mark VII released by Sumlock comptometer of the UK). In 1890 W. T. Odhner got the rights to manufacture his calculator back from Königsberger & C , which had held them since it was first patented in 1878, but had not really ...

  8. Low-density parity-check code - Wikipedia

    en.wikipedia.org/wiki/Low-density_parity-check_code

    During the encoding of a frame, the input data bits (D) are repeated and distributed to a set of constituent encoders. The constituent encoders are typically accumulators and each accumulator is used to generate a parity symbol. A single copy of the original data (S 0,K-1) is transmitted with the parity bits (P) to make up the code symbols. The ...

  9. Hydraulic intensifier - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_intensifier

    The water jet system's cutting head restricts the water flow to generate pressure and direct it onto the workpiece. A holding tank, called a hydraulic accumulator, is used to reduce pressure vibrations at the output end. The more recently developed parallel hydraulic intensifier also uses oscillating pistons to compress water.
