    • The present invention discloses a portable folding tattoo chair comprising a left part (100) and a right part (200), the left part (100) of the chair comprising a left cushion (101), a left fixing plate (102), a left fixing frame (103) and a left footing support (104); the right part (200) of the chair comprising a right cushion (201), a right fixing plate (202), a right fixing frame (203) and a right footing support (204); the left part (100) and the right part (200) of the chair being rotatable so as to be folded together, the left footing support (104) and the right footing support (204) being rotatable to be folded up. The tattoo chair in unfolding states may provide various auxiliary modes for different tattoo positions. The chair can also be folded after use to save space and transportation cost. The chair can be used as a pushcart to add functionality.

    • A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.
    • 一种用于识别无线媒体服务的服务质量下降的方法和装置。 无线媒体服务具有已知的预期分组生成速率,其可以由设备基于在启动媒体服务时选择的编解码器和有效载荷大小来确定。 在接收装置中,从另一终端点实际接收到的分组的分组在一段时间内进行计数,并将该数量与根据已知分组生成速率预期的分组数进行比较。 从该比较可以确定分组丢失率。 如果丢包率超过阈值级别,则设备可能发出用户警告,终止服务或采取其他操作。 可以基于对应于显着程度的服务质量降级的分组丢失率来建立阈值水平。
