The measuring unit measures a parameter resulted from the contact of the first contact terminal with a first contact of the plug. The data transmission unit transmits to or receives from the electronic accessory a data signal through the first contact terminal. The switching unit selectively connects the first contact terminal electrically to the data transmission unit or measuring unit according to whether the voltage is present or not.

Abstract: In a vehicle-to-vehicle network, a driver may listen to audio generated by other drivers participating in the network. The usability of the audio is enhanced by determining the relative positions of the providing and the receiving vehicles and then distributing received audio to specific speakers in the audio system of the receiving vehicle to create an impression that the sound originates from a source on the line between the two vehicles. The audio distributed to different speakers in the vehicle changes as the relative positions of the two vehicles changes. Volume changes and Doppler effects can be added to the audio if the two vehicles are converging or diverging.

Abstract: Methods, systems and computer-readable medium reduce and/or eliminate errors in coding/decoding of streamed audio due to resetting of decoder state values based on playback buffer access. An inaudible compensation signal is included with the audio signal. The compensation signal is generated having a characteristic selected so that the encoded streamed audio signal substantially matches the reset state values at block boundaries. In an ADPCM example, the compensation signal is chosen such that the sum of the compensation signal and the original audio signal (=the compensated audio signal) has the characteristic that, at the block boundaries, the compensated audio signal matches the initial predictor value.
