Abstract: A wearable device includes various sensors including a microphone, heart rate monitor, pressure sensor, and so forth. The user can set the device to acquire audio data of their speech. For example, if the pressure sensor indicates the device is being worn and the user's heart rate exceeds a threshold value, audio data may be acquired. Onboard the device the audio data is processed in various ways such as detecting whether the audio data includes speech, applying a beamforming algorithm, compressing and encrypting the audio, and so forth. The audio data may be processed onboard the device, sent to another device, or a combination thereof for processing to determine sentiment data indicative of perceived emotional content of the speech. A user interface provides the user with information based on the sensor data, sentiment data, and so forth.

Abstract: This disclosure describes, in part, techniques for switching between communication channels in order to reduce latency of data transmissions. For instance, an electronic device may establish a first network connection with a network device and second network connection(s) with other electronic device(s). The electronic device may then send data received from the network device to the other electronic device(s). In some circumstances, the electronic device may establish a new network connection with the network device, such as on a different communication channel and/or use a different network band. In such circumstances, the electronic device may use one or more techniques to establish new network connections(s) with the other electronic device(s) in order to reduce the latency it takes to send the data received from the network device to the other electronic device(s).

Abstract: This disclosure describes, in part, an electronic device for executing network applications. For instance, the electronic device may establish a connection with a network device. The electronic device may then receive input data from a control device.

In some instances, the electronic device may further receive, using the connection and from the remote system, first timestamp data for outputting the audio data and second timestamp data for displaying the video data. The electronic device may then send the audio data to a control device and the video data to a display device.

Abstract: This disclosure describes, in part, techniques for conserving power on an electronic device. For instance, at given time intervals, the electronic device may be sending input data to a network device and receiving audio data from the network device. The electronic device may then use one or more techniques to determine when to switch from operating in a first mode, where the electronic device sends and/or receives the data, to operating in a second mode, where the electronic device ceases sending and/or receiving the data. For example, the electronic device may make the determination based on an amount of data stored in a buffer, whether the electronic device receives data, using data received from the network device, and/or the like. Based on the determination, the electronic device may switch to the second mode in order to conserve power.

Abstract: This disclosure describes techniques for implementing and utilizing a transceiver in a communication device that has two separate radio-frequency (RF) power amplifiers that are optimized to transmit signals using separate communication standards. The power amplifiers may be designed to convert a lower-power RF signal into different higher-power signals according to different standard-mandated, output-power limits. In this way, a communication device may arbitrate between two transceiver chains that include respective power adapters in order to convert lower-power RF signals into different higher-power RF signals. The higher-power RF signals may have different output-power levels that are appropriate for the respective communication standards of the separate transceiver chains.
