    • A wireless communication device (100) includes a display (120) having a backlight (124). A backlight controller (126) selectively enables the backlight (124) to minimize power consumption and conserve energy in a battery (132). In one embodiment, a receiver (110) receives a time-of-day message from a remote location to set a timer (122) with the current time-of-day. The current time-of-day is compared with a predetermined time-of-day and the backlight controller (126) enables and disables the backlight (124) at predetermined times-of-day. The wireless communication device (100) may also include a GPS receiver (128), to determine the location of the device. The backlight controller (126) can determine the sunrise or sunset times for the specific location. The GPS data may be used in combination with the time-of-day message. A photosensor (130) can detect ambient light levels and generate an electrical signal corresponding thereto. The backlight controller (126) may use the photosensor (130) to determine ambient light levels and to enable or disable the backlight (124) based only on ambient light levels. The photosensor signal can be used in combination with the time-of-day message and/or the location data from the GPS receiver (128) to control the backlight (124).
    • 无线通信设备(100)包括具有背光(124)的显示器(120)。 背光控制器(126)选择性地使得背光(124)能够最小化电力消耗并节省电池(132)中的能量。 在一个实施例中,接收器(110)从远程位置接收日时消息以设置具有当前时间的定时器(122)。 将当前时间与预定的时间进行比较,并且背光控制器(126)在预定的时间点启用和禁用背光(124)。 无线通信设备(100)还可以包括GPS接收器(128),以确定设备的位置。 背光控制器(126)可以确定特定位置的日出或日落时间。 GPS数据可以与时间消息组合使用。 光传感器(130)可以检测环境光水平并产生与其对应的电信号。 背光控制器(126)可以使用光传感器(130)来确定环境光水平,并且仅基于环境光水平来启用或禁用背光(124)。 光传感器信号可以与来自GPS接收器(128)的日时消息和/或位置数据组合使用以控制背光(124)。

    • A wireless communication device (100) contains a speed-dial storage area (126) containing one or more user-entered destination telephone numbers. An additional memory area (128) contains the plurality of sets of additional digits to be added to the used-entered destination telephone number. The user associates one or more additional sets of digits to a selected user-entered destination telephone number. A control processor (102) automatically adds the associated set of additional digits whenever the user-entered destination telephone number is selected. The sets of additional digits may be pre-programmed by the service provider or programmed by the user. The sets of additional digits may include codes for features such as caller identification transmission, caller identification blocking, message waiting cancellation, and the like. In addition, other sets of digits, such as area codes and other prefixes may be pre-programmed by the service provider or the user. The additional sets of digits may be added to all subsequent calls to the selected user-entered destination telephone number until the control processor (102) is selectively disabled. The processor may be disabled by manual intervention by the user or by turning the power-off to the wireless communication device.
