A method for converting media using mobile devices includes scanning, using a three-dimensional scanner of a mobile device, at least a part of a surface of a media carrier encoding a first media signal, thereby generating a depth image of the surface of the media carrier, and providing, by the mobile device, a second media signal corresponding at least partially to the first media signal encoded on the media carrier, wherein the second media signal is generated based on the depth image of the surface of the media carrier. Furthermore, a mobile device and a system for converting media are defined.

An audio device includes a base portion a power supply circuit arranged on the base portion and configured to output electric power; a rotation body rotatably supported by the base portion and configured to, upon rotation of the rotation body, move a playback point of a piece of music; an electric circuit arranged on the rotation body; and a non-contact power feeding mechanism configured to supply in a non-contact manner the electric power output by the power supply circuit to the electric circuit in which the non-contact power feeding mechanism is arranged on a path from the power supply circuit to the electric circuit.

Examples are provided for establishing a bonded zone comprising a first playback device comprising a respective first wireless radio and a second playback device comprising a second respective wireless radio. The first and second playback devices may establish a bonded zone comprising at least the first and second playback device. While in the established bonded zone, the first playback device may determine that the first playback device is in the established bonded zone and that the first playback device is not currently playing audio in synchrony with the second playback device. Responsive to determining that the first playback device is not playing audio in synchrony, the first playback device may disable communicating via the first wireless radio of the first playback device and send a message to the second playback device to disable communicating via the first wireless radio of the second playback device.

Systems and methods for power conservation on an audio bus through clock manipulation allow a clock signal on an audio bus such as a SOUNDWIRE audio bus to be stopped when there are no pending commands from a master device. The clock signal may resume when a new command from the master device is generated or the master device receives an interrupt from a slave device.

A remote control apparatus is disclosed. The remote control apparatus comprises: a microphone; a communication unit; a storage unit for storing pattern information of a non-audible sound for identification of the locality of an external electronic device; and a processor for broadcasting, through the communication unit, information acquired on the basis of an ambient sound received through the microphone, and when a non-audible sound based on broadcasted information output from an electronic device is received through the microphone, comparing a pattern of the received non-audible sound with pattern information stored in the storage unit, and transmitting a pairing request signal to the electronic device on the basis of a comparison result.

The present disclosure is directed to examples of a lighting data network. In one embodiment, the lighting data network includes a first luminaire, comprising a first wireless communication interface to receive data from a machine and a second luminaire, comprising a second wireless communication interface to receive the data from the first luminaire and a third communication interface to transmit the data to a third party control system.

A circuit includes an AGC adaptation circuit configured to receive a first signal generated based on an AGC output signal from an AGC circuit. The AGC circuit applies an AGC gain to an AGC input signal to generate the AGC output signal. The AGC adaptation circuit determines an observed value of the first signal, and determines a AGC adaptation step size based on the observed value and a predetermined target value associated with the first signal. The AGC adaptation circuit provides a second signal to adjust the AGC gain of the AGC circuit using the AGC adaptation step size.
