In accordance with the present invention, a method and apparatus are provided for processing data in a baseband unit in which compressed signals from remote radio units are sent directly to the switch instead of to a separate conversion device. Thereby, the local input and output bottleneck within processing devices is removed in the data path of the signals between the remote radio units and the baseband unit. This also reduces the number of ports in the switch and bandwidth requirement for the switch. |

Additives for non-aqueous electrolyte and secondary battery using the same
Disclosed are an electrolyte for a secondary battery, and a secondary battery including the same, the electrolyte including an electrolyte salt; an electrolyte solvent; and a compound generating heat through oxidation at voltages higher than drive voltage of a cathode, wherein the compound can decompose or evaporate electrolyte components by oxidation heat, thereby causing gas generation.

Further, the micro lens optics may be implemented as parabolic optics to concentrate the light that is emitted from the embedded light sources. |

Elevated photodiodes with crosstalk isolation
A device includes a plurality of isolation spacers, and a plurality of bottom electrodes, wherein adjacent ones of the plurality of bottom electrodes are insulated from each other by respective ones of the plurality of isolation spacers. A plurality of photoelectrical conversion regions overlaps the plurality of bottom electrodes, wherein adjacent ones of the plurality of photoelectrical conversion regions are insulated from each other by respective ones of the plurality of isolation spacers. A top electrode overlies the plurality of photoelectrical conversion regions and the plurality of isolation spacers. |
