  • Patent number: 11070924
    Abstract: There is provided an apparatus for hearing measurement based on a cochlear model comprising: a processor; and a memory connected to the processor, wherein the memory stores program instructions executable by the processor to output an interface in which n buttons corresponding to n frequency bands into which an audible frequency band is divided at 1/k octave resolution are arranged in a cochlear model, output acoustic signals corresponding to a predetermined hearing threshold in each of the n frequency bands, receive a user's input for whether each of the n frequency bands is inaudible at the predetermined hearing threshold, and output acoustic stimulation signals corresponding to the inaudible frequency band input by the user in predetermined sizes.

  • Publication number: 20210217720
    Abstract: A semiconductor device may include a semiconductor chip in an encapsulant. A first insulation layer may be disposed on the encapsulant and the semiconductor chip. A horizontal wiring and a primary pad may be disposed on the first insulation layer. A secondary pad may be disposed on the primary pad. A second insulation layer covering the horizontal wiring may be disposed on the first insulation layer. A solder ball may be disposed on the primary pad and the secondary pad. The primary pad may have substantially the same thickness as a thickness of the horizontal wiring.

  • Publication number: 20170206057
    Abstract: A method or apparatus for multi-channel audio data control using plural mobile devices comprising steps of detecting user presence through assigned frequency, transmitting audio data to the nearest device from the user based on user presence information, and recognize user gesture to control the audio data. A remote controller held by the user may also have a priority to control audio data.

  • Patent number: 7420412
    Abstract: A multiple power mode amplifier provides a low and a high power mode without using switches. This amplifier may be used in radio frequency (RF) applications such as mobile telephones, pagers, portable digital assistants, and wireless e-mail devices. In the low power mode, the power consumption of the amplifier is reduced, which will increase operation time, especially important for battery-operated devices. In one implementation, the amplifier includes a number of impedance matching network units (130, 140, 150, and 160), impedance transformer (170), and a power stage (120). An implementation provides further power consumption savings by modulating a bias of an amplifier stage.
