  • Patent number: 8379149
    Abstract: A display apparatus includes a signal input unit through which an image signal is input, the image signal comprising a synchronization signal and an active signal; an adjustment signal generating unit that generates an adjustment signal; a signal processing unit that receives the adjustment signal and adjusts the image signal based on the received adjustment signal; and a controller which analyzes the input signal and controls the adjustment signal generating unit to change characteristics of the adjustment signal if the adjustment signal does not lie within a blanking interval between the synchronization signal and the active signal. With this configuration, even when an image signal having a reduced blanking interval between the synchronization signal and the active signal is input, the adjustment signal can be generated within the blanking interval of the image signal, not within the active signal interval.

  • Patent number: 8378202
    Abstract: An instrument-playing portable communication device is provided. The device includes an instrument-playing key unit having one or more keys, provided on a body of the instrument-playing portable communication device. When a user selects a chord of a selected instrument by pressing at least one of the one or more keys, the instrument-playing key unit converts the at least one key press into a first signal. The device also includes a sensor unit mounted in the body, for sensing a motion of a user. When the user presses the at least one of the one or more keys and moves in a location near the sensor unit, the sensor unit senses a motion of the user and converts the motion into a second signal. The device further includes a controller for receiving the first signal from the instrument-playing key unit and the second signal from the sensor unit, generating a tone frequency of the selected instrument based on the received signals, and converting the tone frequency into a tone.

  • Patent number: 8379755
    Abstract: An RF transmitter filter for use in a wireless communication system is disclosed. The filter includes a waveform detector to detect a power level of a transmitted data stream on a symbol-by-symbol basis. The filter also includes a processor to select a combination of filter parameter values according to the power level. The RF transmitter filter selects and adjusts filter parameters (i.e., number of taps or filter length, word length, coefficient quantization, sampling rate, tap delay, sampling bits, etc.) based on signal waveform characteristics. The adjustments limit the transmitted bandwidth and allow transmitted signals to meet an emission mask, while still enabling a receiver to recover the correct sample values of transmitted symbols. The filter further includes a reconfigurable digital filter to filter the transmitted data stream according to the combination of filter parameters.
