    摘要： The technology relates to establishing wireless communication links, or connections, between a first audio accessory device, a second audio accessory device, and a client computing device. After receiving signals from the client computing device to initiate audio output, the first audio accessory device and the second audio accessory device may both perform a series of steps in parallel to establish connections with the client computing device and with each other. The series of steps may include relaying one or more acknowledgement (ACK) signals between the audio accessory devices in order to confirm proper receipt of the signals from the client computing device at both audio accessory devices. Alternatively, the series of steps may include transmitting a jamming signal from one of the audio accessory devices in order to prevent an ACK signal from the other audio accessory device from reaching the client computing device and initiating audio output.

    摘要： This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.

    摘要： The technology provides for a pair of earbuds. For instance, a first earbud may include a first antenna, and a second earbud may include a second antenna. The pair of earbuds may further include one or more processors configured to receive, from the first antenna, a first signal from a beacon, and receive, from the second antenna, a second signal from the beacon. Based on the first signal and the second signal, the one or more processors may determine at least one signal strength. The one or more processors may determine a position of the user relative to the beacon based on the at least one signal strength.
