摘要： An accessory strobe device for a mobile device may operate to provide illumination at the same time as an internal built-in strobe (flash) of the mobile device. The accessory strobe device may receive a single, unidirectional signal from the mobile device that provides signals related to the timing of the internal strobe. The accessory strobe device may process the received signal to control its illumination using the timing and relative intensity levels of the internal strobe during metering and main (normal) flash operations associated with a camera on the mobile device. With the accessory strobe device operating using timing and relative intensity levels in a predetermined relationship with the timing and relative intensity levels of the internal strobe, the accessory strobe device may be used to complement the internal strobe during the metering and main (normal) flash operations for the camera.

摘要： A system and method to process audio data received over the ARC or eARC interface of HDMI from audio sources are provided. A media device may receive compressed audio data in a number of data formats. The media device may convert between the audio formats provided by the audio sources and the audio formats supported by audio playback devices. The media device may inspect frames of audio data to determine if the frames are to be decoded. The frame may be decoded and subsequently encoded into the data formats supported by the audio playback devices. To reduce latency, the media device may enable a pass-through mode to bypass the decoding of the frames to allow the frames to be decoded at the audio playback devices. A bi-directional loopback application may route audio data received over the ARC or eARC interface from the audio sources to the audio playback devices.

摘要： A system and method to mitigate the temporary loss of the input sampling clocks when receiving audio data over the ARC or eARC interface of HDMI are provided. A media device may substitute an externally generated clock derived from a local crystal oscillator of the media device for the missing input sampling clock. The external clock may be synchronized to the frequency of the input sampling clock. The media device may synchronize the external clock to the audio data when there is a loss of the input sampling clock. When the input sampling clock of the audio data reappears, the media device may switch back from the external clock to the input sampling clock. When transitioning between the input sampling clock and the external clock, the media device may insert zero padding into the audio data samples to mute any potential glitch in the sound from an audio playback device.

摘要： A wireless power transmitting device transmits wireless power signals to a wireless power receiving device using a wireless power transmitting coil. The wireless power receiving device may transmit data packets to the wireless power transmitting device. The wireless power transmitting device may include a data receiver that is coupled to the wireless power transmitting coil and that receives the transmitted data packets. The data receiver may be configured to demodulate the received data packets. The data packets may include at least preamble bits, start bits, and data bits encoded as biphase half-bit signals in accordance with a predefined wireless power transfer protocol. During demodulation, the receiver may perform preamble detection, start bit detection, and data bit detection by comparing the input signals to corresponding reference patterns using a maximum likelihood sequence detection scheme. Phase recovery may be employed throughout to help provide immunity to phase change.
