Functional jewelry is disclosed. A bracelet includes a plurality of light-emitting diodes (LEDs), a main control unit, and positional and situational sensors, typically including an accelerometer, as well as a decorative, interchangeable fascial layer. The bracelet may also include sensors such as capacitive touch sensors, a microphone, and a color sensor. A radio transceiver within the bracelet is adapted to implement a protocol such as BLUETOOTH 4.0, and is adapted to allow the bracelet to communicate in peer-to-peer or master-slave mode. Two users can pair their bracelets in person, usually with a gestural trigger, for shared light displays, multi-player games, and other types of interactions. Larger groups can pair temporarily and contextually for multi-user displays and interactions, in an ad hoc network with distributed functions. Real-world interactions are communicated to a social network with profiles linked to the individual bracelets.

A biasing circuit providing power to a microphone is disclosed. The biasing circuit includes a first impedance element, a second impedance element, a detection circuit and a control circuit. The first impedance element has a first impedance and is coupled between a first power node and a first terminal of the microphone. The second impedance element has a second impedance and is coupled between a second terminal of the microphone and a second power node. The detection circuit is coupled between the first and second terminals and generates a detection signal according to an analog signal generated by the microphone. The control circuit adjusts the first and second impedances according to the detection signal.

Systems and methods are disclosed in which a playback device transmits a first sound signal including a predetermined waveform. In one example, the playback device receives a second sound signal including at least one reflection of the first sound signal. The second sound signal is processed to determine a location of a person relative to the playback device, and a characteristic of audio reproduction by the playback device is selected, based on the determined location of the person.

A device with microphones can generate microphone signals during an audio recording. The device can store, in an electronic audio data file, the microphone signals, and metadata that includes impulse responses of the microphones. Other aspects are described and claimed.

A device for sensing a motion of a deflectable surface includes a deflectable element having a first side beam deflectable and includes a reflective surface at a second side of the deflectable element, proposing the first side. The device includes an optical emitter for emitting an optical signal towards the reflective surface and an optical receiver for receiving a reflected optical signal from the reflective surface and for providing a reception signal based on a reflective optical signal. The device includes a control unit in communication with the optical receiver for determining information related to the motion of the deflectable element based on the reception signal.
