    • An electronic device and a method for automatically converting text to be displayed on a display screen of an electronic device into a speech signal when ambient light conditions affect viewing of the text. The method is performed by the electronic device and the method includes receiving a command to display text on the display screen and determining if an ambient light signal provided by an ambient light sensor is above a pre-determined viewing threshold. This ambient light signal corresponds to ambient light conditions adjacent the display screen. The method also includes automatically converting the text to a speech signal when the ambient light signal is above the pre-determined viewing threshold. Suitably, there is performed a step of emitting the speech signal in an audible form from a speaker.
    • 一种当环境光条件影响文本观看时,将电子设备的显示屏幕上显示的文本自动转换为语音信号的电子设备和方法。 该方法由电子设备执行,并且该方法包括接收在显示屏幕上显示文本的命令,并确定由环境光传感器提供的环境光信号是否高于预定的观看阈值。 该环境光信号对应于与显示屏相邻的环境光条件。 该方法还包括当环境光信号高于预定观看阈值时自动将文本转换为语音信号。 适当地,执行从扬声器发出声音形式的语音信号的步骤。

    • A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of spiral tracks, wherein each spiral track comprising a high frequency signal interrupted at a predetermined interval by a sync mark. An offset r0 representing a difference between an axial rotation of the disk and an axial rotation of the spiral tracks is estimated. Radial dependent timing compensation values are generated in response to the estimated r0. A phase error is generated in response to the sync marks in the spiral track crossings. A control signal is generated in response to the phase error and the radial dependent timing compensation values, and a frequency of an oscillator is adjusted in response to the control signal.
    • 公开了一种磁盘驱动器,包括在包括多个螺旋轨道的盘上致动的磁头,其中每个螺旋轨道包括以预定间隔以同步标记中断的高频信号。 估计表示盘的轴向旋转与螺旋轨迹的轴向旋转之间的差异的偏移r​​0。 响应于估计的r0产生径向相关定时补偿值。 响应于螺旋轨道交叉中的同步标记产生相位误差。 响应于相位误差和与径向相关的定时补偿值产生控制信号,并且响应于控制信号调整振荡器的频率。
