    • Various techniques that relate to prolonging the battery life on a portable electronic device during the buffering and playback of audio broadcast data are provided. In accordance with disclosed embodiments, upon detecting a low power state, the device may implement one or more low power actions, including starting, continuing, or stopping one or more audio broadcast functions, such as buffering or playing back audio broadcast data, to reduce overall power consumption, and thus prolong battery life. In one embodiment, a user may specify one or more low power actions that are to be implemented during a low power state by configuring user settings stored on the device. In another embodiment, the device, upon detecting a low power state, may prompt the user to make a selection from a listing of selectable low power action options and perform the selected low power action.
    • 提供了涉及在音频广播数据的缓冲和重放期间延长便携式电子设备上的电池寿命的各种技术。 根据所公开的实施例,在检测到低功率状态时,设备可以实现一个或多个低功率动作,包括启动,继续或停止一个或多个音频广播功能,例如缓冲或重放音频广播数据,以减少 总体功耗,从而延长电池寿命。 在一个实施例中,用户可以通过配置存储在设备上的用户设置来指定要在低功率状态下实现的一个或多个低功率动作。 在另一个实施例中,该装置在检测到低功率状态时可以提示用户从可选择的低功率动作选项的列表中进行选择并执行所选择的低功率动作。

    • In this invention, when security policy is attached to a file, a device protection manager is given the protected file's name. If the file is a special device file, then the device manager records the device specification in a device database. When a device access occurs, the device specification is extracted from the special device file used in the access. This extracted device specification is then used to search the device database. If a matching device specification is found in the database and the accessed device file has the same name as the protected resource, then authorization policy rules on that resource determine the access. If the match is a different device file name from the protected file name for the same device, then the search continues until the exact accessed device is found or until all device specification matches are found. In the absence of an exact device file match, all the matching device files are presented to the external security manager for authorization checking and the most restrictive outcome prevails.
    • 在本发明中,当将安全策略附加到文件时,设备保护管理器被给予受保护文件的名称。 如果文件是特殊设备文件,则设备管理器将设备规范记录在设备数据库中。 当设备访问发生时,从访问中使用的特殊设备文件中提取设备规范。 然后使用提取的设备规范来搜索设备数据库。 如果在数据库中找到匹配的设备规范,并且访问的设备文件具有与受保护资源相同的名称,则该资源上的授权策略规则确定访问。 如果匹配是与同一设备的受保护文件名不同的设备文件名,则继续搜索,直到找到精确访问的设备,或者直到找到所有设备规格匹配为止。 在没有确切的设备文件匹配的情况下,所有匹配的设备文件都会被提供给外部安全管理器进行授权检查,并且限制最大的结果将占优势。
