  • Patent number: 8892176
    Abstract: An apparatus and method for reducing the power consumption of a Base Station (BS) in a multi antenna system are provided. The method for reducing the power consumption of the BS includes identifying an amount of resources being in use for communication, determining whether to convert at least one Radio Frequency (RF) unit into a power saving mode considering the amount of resources, if converting at least one RF unit into the power saving mode, turning OFF a power supply of a power amplifier of at least one of at least two antenna paths constituting the at least one RF unit converted into the power saving mode, and increasing a gain of at least one antenna path turning ON a power supply such that a transmission Power Spectral Density (PSD) is not changed according to the power saving mode conversion.

  • Patent number: 8072039
    Abstract: An energy conversion film and a quantum dot film which contain a quantum dot compound, an energy conversion layer including the quantum dot film, and a solar cell including the energy conversion layer. The films act as cut-off filters blocking light of a particular energy level using the light absorption and emission effects of quantum dots and can convert high energy light to low energy light. The efficiency of a solar cell may be improved by providing the cell with a film that converts light above the spectrum-responsive region to light in the cell's spectrum-responsive region. The absorption wavelength region of the films can be broadened by providing the quantum dot compound in a variety of average particle sizes, for example, by providing a mixture of a first quantum dot compound having a first average particle size and a first quantum dot compound having a second average particle size.
