  • Patent number: 10656712
    Abstract: This patent relates to a mobile terminal and a method of controlling an operation of the same. The method of controlling an operation of a mobile terminal includes displaying a file list and scroll arrows for scrolling the file list on a touch screen. When the scroll arrow is touched and entered, the file list is scrolled at a scroll speed previously set in response to a time when the scroll arrow is touched and entered. A vibration signal to identify at least one of a scroll speed and a current scrolling position of the file list is provided. Accordingly, when a file list is scrolled, a scroll speed or a current scrolling position can be easily identified by a tactile sense.

  • Patent number: 10469128
    Abstract: Analog echo cancellation with Digital-to-Analog Converter (DAC) noise suppression may be provided. First, a test signal may be sent through an echo cancellation pathway during a downstream silence period and an upstream silence period. The echo cancellation pathway may comprise an electronic element. Next, a loopback response signal may be received in response to sending the test signal through the echo cancellation pathway. Then a channel response model may be created that characterizes a channel response of the loopback response signal and a non-linear model may be created that characterizes a non-linearity of the electronic element. Next, for a downstream signal, a non-linear component may be generated based on the created non-linear model. The generated non-linear component may be convolved with the created channel response model. The convolved non-linear component may then be subtracted from an upstream signal.
