Abstract: A method and apparatus for recovering from a low power state in a computing system is disclosed. In one embodiment of the method, the computing system enters the low power state from a standard power state after an activity detector indicates a user controlled peripheral device connected to the computer system has been inactive for a period of time. To enter the low power state, the method disconnects the user controlled peripheral device from a host controller, while continuing to supply power to the user controlled peripheral device and shutting off power to the host controller. The method returns the computer system to the standard power state when the activity detector indicates the user controlled peripheral device has become active. To return to the standard power state, power is restored to the host controller and the user controlled peripheral device is reconnected to the host controller.

Abstract: Methods and apparatus for reduction of interference between a plurality of wireless interfaces. In one exemplary embodiment, a device having a first (e.g., Wi-Fi) interface and a second (e.g., Bluetooth) interface monitors interference between its interfaces. A reduction in transmit power of the Wi-Fi module causes a disproportionately larger reduction in undesirable interference experienced at the Bluetooth antennas. For example, when the Bluetooth interface detects interference levels above acceptable thresholds, the Wi-Fi interface adjusts operation of one or more of its transmit chains based on various conditions such as duty cycle, Received Signal Strength Indication (RSSI), etc. Various embodiments of the present invention provide simultaneous operation of WLAN and PAN interfaces, without requiring time division coexistence, by reducing power on a subset of interfering antennas.

Abstract: The embodiments set forth herein disclose techniques for enabling a user device to seamlessly establish a secure, high-bandwidth wireless connection with a vehicle accessory system to enable the user device to wirelessly stream user interface (UI) information to the vehicle accessory system. To implement this technique, a lower-bandwidth wireless technology (e.g., Bluetooth) is used as an initial means for establishing a Wi-Fi pairing between the user device and the vehicle accessory system. Wi-Fi parameters associated with a Wi-Fi network provided by the vehicle accessory system can be communicated to the user device using the lower-bandwidth wireless technology. A secure Wi-Fi connection can then be established between the user device and the vehicle accessory system using the provided Wi-Fi parameters. The embodiments also disclose a technique for enabling the user device to automatically reconnect with the vehicle accessory system in a seamless manner (e.g., when returning to a vehicle).

Abstract: A system and method for routing communication to a common audio output device connected to each of two or more audio signal source devices. For each of the two or more audio signal source devices, a set of inputs are assessed. The set of inputs include: an operational state of the audio signal source device, an activity the audio signal source device, an audio-producing application being executed by the audio signal source device, and a degree of user activity with the audio-producing application being executed by the audio signal source. At a point in time, an audio routing score is generated for each of the two or more audio signal source devices according to a weighted calculation of the set of inputs based on the assessing. Finally, an audio signal routing decision is made, to route an audio signal from one of the two or more audio signal source devices to the audio output device, based on the audio routing score for each of the two or more audio signal source devices.

Abstract: Intelligent handoff across different content modalities during streaming of content is discussed herein. Content modalities represent different mechanisms by which content may be streamed to a playback device and include transport modality, source modality, and playback modality. Electronic devices may detect, a change in an operating condition of the streaming content and may make a determination as to whether the change triggers a hand-off involving one or more of these modalities.
