Abstract: After detecting an access-intent operation, an electronic device establishes a connection with a second electronic device using a communication protocol. The electronic devices exchange identifiers, and the second electronic device provides information specifying a preferred channel to use with a second communication protocol. Based at least in part on the preferred channel of the second electronic device and on communication contexts of the electronic devices, the electronic device selects a channel and transmits to the second electronic device information specifying the selected channel. The electronic device remotely accesses credential information based on the exchanged identifiers, and using the credential information, the electronic devices establish a secure connection via the selected channel using the second communication protocol. The electronic device determines a distance to the second electronic device using wireless ranging via the secure connection. When the electronic devices are proximate to each other, the electronic device can be unlocked.

Abstract: Systems and processes for operating an intelligent automated assistant are provided. For example, a first speech input is received from a user. In response to receiving the first speech input, a response is provided. A first output is provided corresponding to a digital assistant in a first state, and a second speech input is received from the user. A first plurality of values is obtained. Based on the first plurality of values, a first confidence level corresponding to the second speech input is obtained. In accordance with a determination that the first confidence level exceeds a first threshold confidence level, a second output is provided corresponding to the digital assistant in a second state. The second speech input continues to be received.

Abstract: Systems and processes for operating an intelligent automated assistant are provided. An example method includes receiving, from one or more external electronic devices, a plurality of speaker profiles for a plurality of users; receiving a natural language speech input; determining, based on comparing the natural language speech input to the plurality of speaker profiles: a first likelihood that the natural language speech input corresponds to a first user of the plurality of users; and a second likelihood that the natural language speech input corresponds to a second user of the plurality of users; determining whether the first likelihood and the second likelihood are within a first threshold; and in accordance with determining that the first likelihood and the second likelihood are not within the first threshold: providing a response to the natural language speech input, the response being personalized for the first user.

Abstract: Wi-Fi link health monitoring by a wireless device. Signal strength (e.g., RSSI) of a Wi-Fi link may be monitored. If the signal strength is low, further link quality metrics may be monitored. If it is determined that health of the Wi-Fi link is poor based on monitoring signal strength and other link quality metrics, roaming to a different Wi-Fi network may be performed, the Wi-Fi link may be disconnected, and/or an application processor of the wireless device may be woken.
Abstract translation: Wi-Fi通过无线设备链接健康状况监控。 可以监视Wi-Fi链路的信号强度（例如，RSSI）。 如果信号强度较低，则可能会监控进一步的链路质量度量。 如果基于监视信号强度和其他链路质量度量确定Wi-Fi链路的健康状况不佳，则可以执行漫游到不同的Wi-Fi网络，Wi-Fi链路可能被断开，和/或 可以唤醒无线设备的应用处理器。

Abstract: A method, station and computer readable storage medium used to perform opportunistic roaming procedures. A station joined to a basic service set (BSS) of an access point (AP) performs a method including determining a roam profile for the station, the roam profile indicating at least one of available operating bands or available APs for the station, determining a first value associated with a network parameter of the joined AP, determining at least one roam candidate AP having a second value associated with the network parameter corresponding to the roam candidate AP, wherein the first and second values are a received signal strength indicator, determining whether a predetermined criteria value is satisfied based upon the first and second values, wherein the predetermined criteria value is a minimum difference between the first value and second value and roaming to the roam candidate AP when the predetermined criteria value is satisfied.
