Abstract: Methods and systems provide control of media synchronization using time stamp pairs. In an embodiment, a first device may request a time stamp from a second device. The first device may determine any de-synchronization between the first and second devices based on the requested time stamp and characteristics of the request. The first device may define a rate scalar based on the determined de-synchronization. A sample rate conversion may be performed for the first device based on the rate scalar such that the outputs of the first device and the second device are synchronized.

Abstract: A method for reconfiguring a bus device from a first configuration into a second configuration, wherein the second configuration is not visible to, and is not selectable by, an unauthorized host device that connects to the bus device through a peripheral port of the bus device is described. In the bus device, a received message transmitted by the authorized host device through the peripheral port of the bus device to which the authorized host device is connected is parsed and an instruction to reconfigure the bus device from the first configuration into the second configuration is detected. Responsive to detecting the instruction, a daemon signals reconfiguration of the bus device into the second configuration, and responsive to the daemon signaling, the bus device is reconfigured into the second configuration. Other embodiments are also described.

Abstract: A bridge element is provided for establishing clock synchronization across network elements including a first network element using a first clock synchronization transport protocol and a second network element using a second clock synchronization transport protocol different from the first clock synchronization transport protocol. The bridge element includes a port, a protocol translation port and an interconnect structure. The port may receive a clock synchronization signal from the first network element using the first clock synchronization protocol. The interconnect structure may receive the clock synchronization signal from the port. The protocol translation port may receive the clock synchronization signal from the interconnect structure, translate the clock synchronization signal between the first clock synchronization transport protocol and the second clock synchronization transport protocol, and provide the translated clock synchronization signal to the second network element using the second clock synchronization protocol.

Abstract: The embodiments set forth a technique for enabling a computing device to securely configure a peripheral computing device. According to some embodiments, the method can include the steps of (1) approving a request received from the peripheral computing device to engage in a setup procedure for the peripheral computing device, (2) receiving, from the peripheral computing device: (i) an audio signal that encodes a password and timing information, and (ii) a light signal. Additionally, the method can involve, in response to identifying that the timing information correlates with the light signal: (3) extracting the password from the audio signal, and (4) establishing a communication link with the peripheral computing device based on the password. In turn, the method can involve (5) providing configuration information to the peripheral computing device over the communication link.

Abstract: An electronic device has one or more microphones that pick up a sound. At least one feature extractor processes the audio signals from the microphones, that contain the picked up the sound, to determine several features for the sound. The electronic device also includes a classifier that has a machine learning model which is configured to determine a sound classification, such as artificial versus natural for the sound, based upon at least one of the determined features. Other aspects are also described and claimed.

Abstract: An electronic device includes a processor, and a memory containing instructions that, when executed by the processor, cause the electronic device to learn a sound emitted by a legacy device and to issue an output when the electronic device subsequently hears the sound. For example, the electronic device can receive a training input and extract a compact representation of a sound in the training input, which the device stores. The device can receive an audio signal corresponding to an observed acoustic scene and extract a representation of the observed acoustic scene from the audio signal. The electronic device can determine whether the sound is present in the observed acoustic scene at least in part from a comparison of the representation of the observed acoustic scene with the representation of the sound. The electronic device emits a selected output responsive to determining that the sound is present in the acoustic scene.
