  • Patent number: 7287100
    Abstract: A portable computer system includes a portable computer and an integrated device both having wireless data transmission interface. The integrated device is connected to various peripheral devices with different interfaces and controlled by corresponding external port signals. When the portable computer wants to access the peripheral devices, a signal processor integrates and encodes all the external port signals to generate a single encoded signal to be fed to the integrated devices via the wireless transmission interface. After the integrated device receives the encoded signal, a signal processor decodes it to reproduce individual external port signals to be transferred to each corresponding peripheral device to control the operation thereof. During the encoding process, the signal processor may set the priorities according to the properties of each signal and add the identification information of the portable computer.

  • Patent number: 7251134
    Abstract: An extended fin array has a main heat-dissipation module and an extended heat-dissipation module. The main heat-dissipation module and the extended heat-dissipation module are stacked to increase the effective convective area to increase the heat-dissipation effect. The extended heat-dissipation module is in the main heat-dissipation module when the heat amount generated by an electronic device is normal. The extended heat-dissipation module extends out from the main heat-dissipation module to increase the heat convection area when the heat amount generated by the electronic device is large.

  • Publication number: 20060126856
    Abstract: A volume control method. An audio device. A portable communication system. First, an audio signal is input. At least one environmental noise is detected. An output gain is then determined based on the environmental noise, and the audio signal is amplified based thereon. The environmental noise comprises noises from various directions and various positions, and the output gain is proportional to the amplitude of the environmental noise. A custom gain is further received, and a sound pressure level (SPL) of the environmental noise is calculated. Therefore the output gain can be determined by summing the sound pressure level and the custom gain.

  • Publication number: 20060099071
    Abstract: A centrifugal fan is described. The centrifugal fan is suitable for a portable electrical apparatus. A tongue shape is formed from a volute sidewall of a casing of the centrifugal fan. The volute sidewall is formed with at least one groove substantially extending horizontally at the tongue shape. Therefore, when the blades rotate to generate a wake flow to blow on a surface of the volute sidewall at the tongue shape, noise generated by the centrifugal fan can be reduced.

  • Publication number: 20050276684
    Abstract: A centrifugal fan with a resonant silencer has a centrifugal impeller and an outer housing. The outer housing has an inlet, an outlet and a resonant silencer. An inlet is positioned along an axial direction of the centrifugal impeller. An outlet is positioned along a radial direction of the centrifugal impeller. The resonant silencer, extended from a cut-off, can reduce noise caused by a vortex. The resonant silencer can be I- or L-shaped. The cut-off can be covered by a net filter, which isolates the resonant silencer from the flow motivated by the centrifugal impeller.
