This disclosure describes, in part, techniques for using presence detection in order to switch between power modes of a display device. For instance, the display device may operate in a first power mode by deactivating a display. While operating in the first power mode, the display device may use a sensor to detect a presence of a possible object. The display device may then switch to a second power mode in order to verify that the possible object is an actual object. In response, the display device may switch to a third power mode by at least activating the display and presenting a user interface using the display. The display device may then receive an interaction. In response, the display device may switch to a fourth power mode by at least presenting content.

Presence-detection modes for display devices

A system and method to manage handover between wireless audio devices (such as earbuds) of primary responsibility for communicating with a third device such as a phone or tablet. A first wireless audio output device manages communications between a third device and a second wireless audio output device. The wireless audio output devices determine the signal quality of the connection between them. If that signal quality drops below a threshold, the wireless audio output devices determine the rate of change of that signal quality. If that quality is dropping rapidly, the wireless audio output devices check to see which has the better connection to the third device. If the second wireless audio output device has a better connection to the third device than that of the first wireless audio output device, then the wireless audio output devices can trigger a handover from the first wireless audio output device to the second wireless audio output device.

Wireless connection management

A system and method includes a first audio device (e.g., a primary wireless earbud) connected to a second audio device (e.g., a secondary wireless earbud) using a first wireless connection. The first audio device is also connected to a user device (e.g., a smartphone or smart watch) using a second wireless connection. The second audio device receives data, such as packets, sent from the third device to the first device by monitoring the second wireless connection. If a signal quality of the second wireless connection as determined by the first and/or second audio device changes, the first and/or second audio device may exchange primary/secondary roles and/or enable or disable wireless signal amplifiers.
