  • Patent number: 8352084
    Abstract: A solar power generation system comprising: plural customers each having a solar panel, a power convertor for converting DC output from the solar panel into AC output, an output controller for suppressing the power convertor output which becomes higher than a predetermined value, a measuring unit for measuring the amount of sold power, the amount of purchased power and the amount of generation-suppressed power; and an watt-hour meter measurement data adjusting unit linked with the plural customers via communication lines. The watt-hour meter measurement data adjusting unit calculates provisional generation-suppressed power amounts that make the burdens of the customers even, and calculates the power amounts to be sold by the customers on the basis of the provisional generation-suppressed power amounts. Thus, the generation-suppressed power of the solar power generation system can stabilize the power system and the chances for selling power can be fairly allocated to customers having solar panels.

  • Patent number: 5666161
    Abstract: Compressed image data of a desired picture is read out from a memory having compressed image data of a sequential format stored therein and then subjected to an examination with respect to a plurality of frequency components of the read-out compressed image data. Part of the plurality of frequency components is deleted to obtain compressed image data of a quality lower than an original quality of the compressed image data. The obtained compressed image data of the lower quality is decoded and displayed on a display. The plurality of frequency components are deleted in a stepwise manner according to a traffic state of a transmission line through which the compressed image data is to be transmitted. For maintaining a picture frame rate to be constant, the plurality of frequency components may be deleted in a stepwise manner. For obtaining a desired decoding rate, the plurality of frequency components may be deleted in a stepwise manner.
