  • Patent number: 8199254
    Abstract: In a device for separating a synchronous signal in a video signal, a capacitor receives the video signal to obtain a coupling signal, a level determining circuit receives the coupling signal and compares a voltage level of the coupling signal with a number of reference voltages. The reference voltages define several reference voltage ranges, one of which is a predetermined reference voltage range. The level determining circuit outputs an adjusting signal according to a reference voltage range corresponding to a minimum voltage level of the coupling signal within a predetermined time period. A level adjusting circuit has several current sources for receiving the adjusting signal and thus controls the current sources to adjust a DC level of the coupling signal. A synchronous signal separating circuit separates the synchronous signal from the coupling signal when the minimum voltage level of the coupling signal is substantially within the predetermined reference voltage range.

  • Patent number: 8199881
    Abstract: A discretely addressable large-area X-ray system is provided. The large-area X-ray system can output a uniform flux of X-rays over a large area using discrete addressing operation of transistors connected to cathodes of electron emitters. Thus, when applied to a medical device, the system can minimize damage inflicted upon the human body because it enables effective imaging of only a desired specific portion of the body. Furthermore, the large-area X-ray system can be simply implemented by current switching using transistors. Thus, the system can be very easily applied to other applications.

  • Patent number: 8199907
    Abstract: An echo canceler uses an adaptive filter to remove an echo of a far-end input signal from a near-end input signal. Filter coefficients are calculated and updated while the far-end signal is active. While the far-end signal is silent, substitute filter coefficients are similarly calculated to be swapped in as initial values for the filter coefficients when the far-end signal changes from silent to active. The substitute filter coefficients are generated from a simulated far-end signal and a simulated near-end signal obtained by combining corresponding samples in different intervals of the far-end and near-end input signals. To facilitate convergence of the substitute filter coefficients, use of the simulated far-end and near-end signals is disabled when the corresponding samples cancel out.
