摘要： An ultrasound and radio frequency technology is used to implement presence sensor capability for wireless devices such as, a laptap device. For example, the laptap device connects to a station device through a WiFi signal. In this example, the WiFi signal may include a data packet that synchronizes internal clocks of the laptap device with the station device. Further, the data packet may include transmitting time information for an ultrasound audio signal generated by the station device. The ultrasound audio signal is received by the laptap device that calculates time of flight (TOF) of the ultrasound audio signal. The TOF may be used to determine actual distance of the wireless device (e.g., laptap device) to the station device.
摘要翻译：使用超声波和射频技术来实现诸如laptap设备之类的无线设备的存在传感器能力。例如，笔记本设备通过WiFi信号连接到站设备。在该示例中，WiFi信号可以包括数据分组，该数据分组使该分路器装置的内部时钟与站装置同步。此外，数据分组可以包括发送由站设备生成的超声音频信号的时间信息。超声波音频信号由计算出超声音频信号的飞行时间（TOF）的笔记本装置接收。可以使用TOF来确定无线设备（例如，laptap设备）到站设备的实际距离。
