The electronic device includes a communication unit for connecting a network to a second electronic device, an information collection module, which collects information necessary for determining a location of the second electronic device, and at least one processor, which determines the location of the second electronic device, based on the information collected by the information collection module, defines contents to reproduce in the second electronic device, based on the location, and provides the contents to the second electronic device.

Abstract: An audio signal output level control method used in an audio device includes detecting input levels of an audio signal, determining control modes to be applied to the audio signal based on the input levels of the audio signal, controlling the input levels of the audio signal according to the control modes, and determining output levels corresponding to the controlled input levels.

Abstract: An electronic device manages a plurality of microphones comprising a first microphone unit installed in a front side of the electronic device, a second microphone unit installed in a back side of the electronic device and a third microphone unit installed at a position within the electronic device. At least one sensor installed in the electronic device senses a usage condition of the electronic device comprising a physical orientation of the electronic device relative to a plane. A processor selectively operates at least two of the first, second and third microphone units in response to the sensed usage condition of the electronic device.

Abstract: A microphone module for an electronic device is provided. The microphone module includes a window having at least one microphone hole in a part of an edge of the window, a microphone installed in a position corresponding to the microphone hole of the window, and a case frame coupled with the window and forming an appearance of the electronic device. The microphone module receives an external voice through the microphone hole of the window.

Abstract: The present invention relates to the use of internal promoters in mammalian expression vectors including plasmid vectors and enhancer-deleted retroviral vectors. The retroviral vectors have improved safety and optimal levels of transgene expression and vector titers.

Abstract: An audio signal control method and apparatus for hearing protection are disclosed. The audio signal control method includes: producing an output level of an audio signal being input; determining whether the ratio of an output time of the audio signal within a preset time duration to a permissible time corresponding to the produced output level is greater than or equal to a limit reference value; and limiting, when the ratio of the output time to the permissible time is greater than or equal to the limit reference value, the output level of the audio signal to a preset level.

Abstract: The present invention relates to a thermoplastic resin composition. In more particular, a thermoplastic resin of graft ABS polymer and heat-resistant copolymer contains acryl-based resin, peroxide-based additive, or cross-linking additive, so that the thermoplastic resin composition of the present invention is effective in processing of a colored heat resistant ABS resin by having excellent cold stress whitening reduction and strength property, without lowering other properties as well as giving excellence in hot-tool weldability, pigmentation and paint spread property which are more important in post process, and maintaining the mechanical property as well as giving excellent heat-resistance and low gloss property.
