    • A wireless device may alert a wireless smart card reader that communication of data between the wireless device and the wireless smart card reader is probably imminent by sending an activation alert. Upon receipt of the activation alert, if the wireless smart card reader is in a low-power state, the wireless smart card reader may enter a higher-power state. If the wireless smart card reader is in the higher-power state upon receipt of the activation alert, the wireless smart card reader may remain in the higher-power state until a timeout period has expired. The wireless device may instruct the wireless smart card reader to enter the low-power state by sending a deactivation alert if the wireless device detects that communication of data between the wireless device and the wireless smart card reader is not likely to occur within a specified period of time.
    • 无线设备可以警告无线智能卡读取器,通过发送激活警报,可能迫使无线设备和无线智能卡读卡器之间的数据通信。 在接收到激活警报时,如果无线智能卡读卡器处于低功率状态,则无线智能卡读卡器可能进入较高功率状态。 如果无线智能卡读卡器在接收到激活警报时处于较高功率状态,则无线智能卡读卡器可以保持在较高功率状态,直到超时时间段到期。 如果无线设备检测到在无线设备和无线智能卡读卡器之间的数据通信不太可能在规定的时间内发生,则无线设备可以通过发送去激活警报来指示无线智能卡读卡器进入低功率状态 的时间。

    • The present disclosure relates generally to the management of privileges associated with certain applications that are accessible by users of electronic equipment, such as, for example, networked computers, mobile wireless communications devices, and the like. In particular, the disclosure is directed to systems and methods for managing privileges associated with particular applications and for revoking these privileges in a timely and robust manner. For example, the device keeps track of which applications get access to which privileges. When policies or application control changes, the system detects which privileges have been revoked for which applications. This can be accomplished by simply comparing the old set of privileges with the new set of privileges. For each revoked privilege for a given application, the system determines if the application has ever accessed that privilege in the past. If an application has accessed a privilege that is now revoked at any time in the past, the device is reset. To ensure that privileges that may be passed between applications are not overlooked, the device is arranged to perform a reset if any revoked privilege accessible by the device is one that may be passed between applications.
    • 本公开一般涉及与电子设备的用户可访问的某些应用相关联的特权的管理,诸如联网计算机,移动无线通信设备等。 特别地,本公开涉及用于管理与特定应用相关联的特权并以及时和鲁棒的方式撤销这些特权的系统和方法。 例如,设备跟踪哪些应用程序可以访问哪些权限。 当策略或应用程序控制更改时,系统会检测哪些权限已被吊销哪些应用程序。 这可以通过简单比较旧的权限集与新的一组特权来实现。 对于给定应用程序的每个撤销权限,系统确定应用程序是否曾经访问过该权限。 如果应用程序已访问过去任何时候已被撤销的特权,则设备将被重置。 为了确保应用程序之间可能传递的权限不被忽略,设备被安排为执行重置,如果设备可访问的任何撤消的权限是可以在应用程序之间传递的特权。
