    • Particular embodiments receive a plurality of touch events detected by a touchscreen. The display refresh rate may not be synchronized with a touch response rate of the touchscreen. Each touch event may be associated with at least one position on the touchscreen. A correlation between the touch events and a display refresh rate of the touchscreen may be determined. At least one position for display output may be extrapolated based on the touch events for the purpose of smoothing the display output. Additional positions for display output may be extrapolated based on the touch events for the purpose of predicting display output. Display information may be provided based on the touch events and the extrapolated positions.
    • 具体实施例接收由触摸屏检测到的多个触摸事件。 显示刷新率可能不与触摸屏的触摸响应率同步。 每个触摸事件可以与触摸屏上的至少一个位置相关联。 可以确定触摸事件与触摸屏的显示刷新率之间的相关性。 为了平滑显示输出,可以基于触摸事件来外推至少一个用于显示输出的位置。 显示输出的附加位置可以基于触摸事件进行外推,以便于预测显示输出。 可以基于触摸事件和外推位置来提供显示信息。

    • In a method and apparatus suitable to convey timely information for facilitating accurate reception of transmitted data, a pilot signal is modulated to convey information. The information may facilitate efficient interpretation of an associated traffic signal. Modulation of a pilot signal frame may be limited to ensure early detection, and/or to minimize impairment of pilot functionality. In one embodiment, a Secondary Pilot Channel (SPICH) is transmitted at one of several selectable power levels to boost effectiveness of a phase reference, and is modulated to indicate the selected level. Such timely information enables prompt optimal combining of the SPICH with a primary Pilot Channel (PICH), and/or permits processing efficiencies for an associated traffic channel. Pilot signal frames may be transmitted at a predetermined level during a detection preamble portion of a frame to ensure accurate and early detection, and at a more optimal level thereafter.
    • 在适于及时传送信息以便于准确地接收发送数据的方法和装置中,调制导频信号以传送信息。 该信息可以促进相关联的交通信号的有效解释。 可以限制导频信号帧的调制以确保早期检测,和/或最小化导频功能的损害。 在一个实施例中,辅助导频信道(SPICH)以若干可选功率电平中的一个发射,以提高相位参考的有效性,并被调制以指示所选择的电平。 这种及时的信息使SPICH能够与主导频信道(PICH)的及时的最佳组合,和/或允许相关业务信道的处理效率。 可以在帧的检测前导码部分期间以预定级别发送导频信号帧,以确保准确和早期的检测,并且此后的更优选的级别。
