Abstract: The disclosure describes techniques for the isochronous transfer of data between a central device and one or more peripheral devices. For example, the central device may comprise any type of electronic device that is able to distribute data to peripheral devices using a wireless protocol. The isochronous transfer of data from the central device may provide an efficient method for wirelessly delivering data to multiple peripheral devices in an alternating pattern. In some examples, the isochronous transfer of data may help ensure that the peripheral devices receive timely and successful data transfers, improving the overall performance of the network of devices.

Abstract: 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.
