  • Patent number: 9204517
    Abstract: Disclosed is a light emitting device driving apparatus for controlling a light emitting unit including series-connected light emitting device arrays. The apparatus includes a rectifier for rectifying an AC signal, and outputting a ripple current signal according to a result of the rectification, a current adjuster for outputting a selection voltage, and a sequential driving controller connected to channel lines connected to respective output terminals of the light emitting device arrays, the sequential driving controller selectively establishing current paths between the light emitting device arrays and the channel lines, based on a voltage level of the ripple current signal, and adjusting an intensity of current flowing through the channel lines, based on the selection voltage.

  • Publication number: 20050113125
    Abstract: A mobile communication terminal having an antenna and method of using the same is disclosed in which the angle of the antenna is adjusted according to a Specific Absorption Rate (SAR) value of the mobile communication terminal and a user is notified when the SAR value exceeds a predetermined value. The method stores a plurality of SAR values each corresponding to a transmission power of the mobile communication terminal in a memory and determines a current transmission power of the mobile communication terminal in a call state. The method then reads a SAR value which corresponds to the current transmission power from the memory. The angle of the antenna is then adjusted according to the SAR value.
