摘要： An example implementation may involve a media playback system detecting two or more playback devices of a given type. The implementation may further involve transmitting, to a particular playback device of the detected playback devices, an instruction that causes the particular playback device to emit a given sound. The implementation may also involve receiving an identification of the particular playback device and displaying, via a graphical interface, one or more prompts to join the particular playback device into the media playback system.

摘要： In some examples, a control audio management engine is configured to interact with guest audio services in respective guests that have different audio management capabilities. The control audio management engine receives an indication of a start of a first audio in a first guest of the guests, the indication comprising an audio stream. The control audio management engine sends, to a second guest of the guests, control information to affect playback of a second audio that is playing in the second guest.

摘要： Examples relate to communicating synchronization information from a satellite to a power supply device to enable time synchronization between the satellite and the power supply device. The power supply device includes a port to receive, from a modulator, a modulated current corresponding to a power consumption across a dummy load, where a level pattern of the modulated current indicates the synchronization information received from the satellite. The power supply device includes a power consumption analyzer configured to receive a modulated voltage, across a shunt resistor, corresponding to the modulated current and recover, from the modulated voltage, the synchronization information.

摘要： Exemplary embodiments are directed to bidirectional wireless power transfer using magnetic resonance in a coupling mode region between a charging base (CB) and a battery electric vehicle (BEV). For different configurations, the wireless power transfer can occur from the CB to the BEV and from the BEV to the CB.

摘要： An audio signal processing method of an audio signal distribution device including a receiver, a determiner, and a transmitter. The receiver receives information relating to capabilities of a distribution destination device to which an audio signal is distributed. The determiner, based on the capabilities of the distribution destination device in received information, determines a role of processing of the audio signal of each device including an own device and the distribution destination device and generates processing information according to the processing of the audio signal. The transmitter distributes the processing information and the audio signal to the distribution destination device.

摘要： A high-speed serial interface (HSIF) for communicating between an analog front end (AFE) and a System on a Chip (SoC) digital radio via a bi-directional serial bit connection for an OFDM cable modem includes generating Status Frames and Data Frames to be communicated between the tuner and AFE and sending the generated Status Frames and Data Frames on a continual basis. Each Frame is a 10-bit K.28 Comma Sync word followed by a payload and when no data is queued to be communicated, Status Frames are sent asynchronously as filler frames.

摘要： Techniques are described for keyless entry to a structure (e.g., hotel room) utilizing a set-back box. Registrants (e.g., hotel guest) may scan a barcode from their mobile device to check-in to the structure. Upon scanning the barcode or by other means, a mobile device identifier (e.g., a Bluetooth low-energy address (BLE)) is registered and associated with the checked-in structure. Receiving the registered mobile device identifier, the backend server pushes such to the set-back box associated with (e.g., resides in) the checked-in structure. The set-back box is enabled (e.g., BLE enabled) to actively scan addresses of nearby mobile devices. When the registered mobile device identifier is detected within a predetermined signal strength range (e.g., by using received signal strength indicator (RSSI) levels), the set-back box transmits a command to a smart lock (e.g., via BLE or Wifi or other radio) or to a lock controlling backend processor, to open the lock.

摘要： An algorithm for the promotion of terminal nodes to switch nodes in a PLC network reduces overall network overhead and collisions, while ensuring the appropriate selection of a switch node and minimizing the number of levels in a PLC network. It also ensures that the terminal nodes with appropriate signal-to-noise ratios (SNRs) are promoted. It is desirable to have a network with fewer levels. The disclosed approach favors the nodes that are closer to the DC to promote them as switch nodes. This is achieved by waiting for a smaller number of PNPDUs for a node that is closer to the DC in comparison to a node that is farther away from the DC.
