    • The disclosure provides a method and a system for network handover. The method includes: during a process that equipment hands over from a current network to another network, a driver receiving a network-disconnected message, and judging whether the network-disconnected message is sent from a Connection Manager (CM); if the network-disconnected message is sent from the CM, the driver reporting, to an operating system, a first signalling which identifies that the current network is disconnected; and if the network-disconnected message is not sent from the CM, the driver reporting, to the operating system, a second signalling which identifies that the current network is connected. By the adoption of the method and the system, power consumption of the equipment can be reduced.
    • 本公开提供了一种用于网络切换的方法和系统。 该方法包括:在设备从当前网络切换到另一网络的过程中,接收网络断开的消息的驾驶员,以及是否从连接管理器(CM)发送所述网络断开的消息; 如果从CM发送网络断开的消息,则驱动程序向操作系统报告标识当前网络断开的第一信令; 并且如果没有从CM发送网络断开的消息,则驱动程序向操作系统报告标识当前网络连接的第二信令。 通过采用该方法和系统,可以降低设备的功耗。

    • This disclosure describes a wearable fall detection device configured to utilize several methods that facilitate monitoring a wearer of the device. The device comprises a first sensor configured to generate elevation data that represents an elevation of the device, and a second sensor configured to generate acceleration data that represents a magnitude of acceleration of the device. The device also includes a processor configured to determine, based on the elevation data, an elevation of a floor located underneath the wearer, and detect a fall affecting the wearer. Detecting a fall may be done by determining that the acceleration data satisfies a fall hypothesis condition, and determining, based on the elevation data, that the apparatus is vertically displaced from the floor by less than a threshold distance.
    • 本公开描述了一种佩戴式跌倒检测装置,其被配置为利用便于监视该装置的佩戴者的若干方法。 该装置包括:第一传感器,被配置为产生表示装置的高度的高程数据;以及第二传感器,其被配置为产生表示装置的加速度的加速度数据。 该装置还包括处理器,该处理器被配置为基于高程数据确定位于穿戴者下方的地板的高度,并且检测影响穿戴者的跌倒。 可以通过确定加速度数据满足下降假设条件并且基于高程数据确定该装置从地板垂直移位小于阈值距离来进行检测。
