    Abstract: A home appliance and a home appliance system are provided. The home appliance may convert product information into an acoustic signal and externally output the same as a sound. The home appliance system may receive the sound, convert the same into the acoustic signal, and then inversely convert the acoustic signal into the product information and read the same. Accordingly, the home appliance may externally output the acoustic signal as the sound so that the user may be easily notified of transmission. Also, the home appliance system may easily transmit the sound to a management device to read the product information because the sound may be transmitted via a communications network.

  • Digital Automatic Gain Control Apparatus and Method in Burst Mode Optical Receiver
    Publication number: 20100014866
    Abstract: A transimpedance amplifier for a burst mode optical communication converts a burst current signal into differential output voltage signals. Using a multi-level digital AGC mechanism, the transimpedance amplifier is rapidly adapted to a burst signal whose amplitude varies in a wide range. By using an adaptive level detection method, a multi-level digital AGC can be implemented without using ADC. In addition, because the transimpedance amplifier uses a selective reset generation scheme that performs a reset operation for itself after a high power burst, a burst mode operation can be performed without external reset signals. Accordingly, the transimpedance amplifier can be integrated with an optical detector within a TO-can. Furthermore, the transimpedance amplifier can have the burst mode capability and the best sensitivity.
