    摘要: An apparatus and a method for improving communication sound quality in a mobile terminal in order to remove a neighboring noise that occurs together with a user's voice signal in a mobile terminal by discriminating signals occurring at different distances using two microphones and removing a noise. The mobile terminal preferably includes a first microphone, a second microphone, and a voice processor. The first microphone receives a voice signal occurring at a closer distance from the mobile terminal and a voice signal occurring at a longer distance from the mobile terminal. The second microphone receives only a voice signal occurring at the long distance. The voice processor discriminates between the signal occurring at the long distance and the signal occurring at the close distance by receiving voice signals received via the first microphone and the second microphone at different phases.

    摘要: An electroluminescent device in which the intensity of the light emission is enhanced by photopumping with radiation from a radiation source of a suitable photon energy. The photopumping radiation from the radiation source interacts with the wide band-gap semiconductor forming the electroluminescent device so as to, when the device is electrically biased to provide light emission, generate additional carriers that enhance the intensity of the light emission from a light-emitting element present in the wide band-gap semiconductor. A waveguide structure may be integrated into a substrate carrying the electroluminescent device for transferring the radiation from the radiation source to the electroluminescent device. Multiple electroluminescent devices may be arranged in pixels for forming a flat panel display in which certain of the devices are photopumped with radiation.
