Abstract: A handheld computer which contains an LCD display having a digitizing surface to allow pen input. Internal storage takes several forms, such as a large flash ROM area, battery-backed up RAM and an optional hard disk drive. Several alternative communication paths are available, such as the previously mentioned modem, a parallel printer port, a conventional serial port, a cradle assembly connected to the host computer, and various wireless short distance techniques such as radio frequency or infrared transmission. The computer can readily communicate with other sources, particularly to a host desktop computer, to allow automated synchronization of information between the host and the handheld system. Preferably the remote synchronization is performed at several user selectable levels. When the handheld computer is in a cradle and actively connected to the host computer, automatic capture of updated data in the host computer is performed. Several synchronization tehcniqques are utilized to keep track of different types of files. In addition, while communication is established the handheld computer can enter a remote control mode, allowing the user access to files and applications not included in the handheld computer.

Abstract translation: 一种手持式计算机，其包含具有数字化表面以允许笔输入的LCD显示器。 内部存储具有多种形式，例如大型闪存ROM区，电池备份RAM和可选硬盘驱动器。 可以使用几种备选的通信路径，诸如前述调制解调器，并行打印机端口，常规串行端口，连接到主计算机的支架组件，以及诸如射频或红外线传输的各种无线短距离技术。 计算机可以容易地与其他源通信，特别是与主机台式计算机通信，以允许主机和手持系统之间的信息的自动同步。 优选地，远程同步以几个用户可选择的级别执行。 当手持式计算机在托架中并且主动地连接到主计算机时，执行主计算机中更新的数据的自动捕获。 利用多个同步特征来跟踪不同类型的文件。 另外，当建立通信时，手持式计算机可以进入远程控制模式，允许用户访问未包括在手持式计算机中的文件和应用程序。
