    • A dual-view display system (102) includes a dual-view touchscreen display (104) adapted to display a first image including a first menu to a first user positioned at a first location with respect to system (102) and to display a second image including a second menu to a second user positioned at a second location with respect to system (102). The dual-view display system (102) further includes at least one sensor (106, 108) adapted to detect proximity to the dual-view touchscreen display (104) of the first user relative to the proximity to the dual-view touchscreen display (104) of the second user. Menu selection logic (402) identifies a received user touch command as a selection from the first menu or as a selection from the second menu based on the proximity to the dual-view touchscreen display (104) of the first user relative to the proximity to the dual-view touchscreen display (104) of the second user.

    • A method of modulating an infrared headphone interface signal includes providing a first audio signal having an analog audio value. A memory is provided having a plurality of locations and containing digital phase offset values. A clock signal having a clock frequency is provided. A second audio signal having a center carrier frequency that deviates with the analog audio value of the first audio signal is provided. An instantaneous value of the center carrier frequency is determined. The clock frequency is divided by the instantaneous carrier frequency value to calculate a number of samples per cycle. A number of location addresses in the memory is divided by the number of samples per cycle to calculate a memory access interval. The memory is accessed at addresses separated by the memory access interval. The digital phase offset values at the accessed memory addresses are used to reproduce the first audio signal.
    • 调制红外耳机接口信号的方法包括提供具有模拟音频值的第一音频信号。 提供具有多个位置并且包含数字相位偏移值的存储器。 提供具有时钟频率的时钟信号。 提供具有与第一音频信号的模拟音频值偏离的中心载波频率的第二音频信号。 确定中心载波频率的瞬时值。 时钟频率除以瞬时载波频率值,以计算每个周期的采样数。 存储器中的多个位置地址除以每个周期的采样数来计算存储器访问间隔。 存储器在由存储器访问间隔分隔的地址处被访问。 在访问的存储器地址处的数字相位偏移值用于再现第一音频信号。
