    • A mobile information device (MID) incorporates a handset having a primary applications processor, a primary display, a primary input keyboard, a second input keypad, a second display having reduced functionality from the primary display and a card interface. A miniaturized form factor card is received in the card interface which includes a second processor and wireless communications components. The interface provides operable connection from the second processor to the second input keypad and second display. During operations of simple voice call or comparable functions, the primary applications processor, primary display and primary keyboard remain in sleep mode to reduce power consumption for the MID with the call functionality provided by the second processor, second keyboard and second display. During operations requiring higher level functionality, the primary applications processor, primary display and primary keyboard are awakened to provide the necessary capability.
    • 移动信息设备(MID)包括具有主应用处理器,主显示器,主输入键盘,第二输入键盘,具有从主显示器和卡接口的功能减少的第二显示器的手机。 在包括第二处理器和无线通信组件的卡接口中接收小型化形状卡。 该接口提供从第二处理器到第二输入键盘和第二显示器的可操作连接。 在简单语音呼叫或类似功能的操作期间,主应用处理器,主显示器和主键盘保持睡眠模式,以通过第二处理器,第二键盘和第二显示器提供的呼叫功能来降低MID的功耗。 在需要更高级别功能的操作期间,主应用处理器,主显示器和主键盘被唤醒以提供必要的功能。
