A power transfer system is provided and equipped with a torque transfer coupling which includes a clutch and a ball-screw actuator. The apparatus comprises a manually operable joystick which can be used to operate a compact disc player, and to cause it to play the content on the basis of the viewed image of the vinyl record, thus simulating the complete functional capability of a traditional record deck and vinyl record in a compact disc player. In addition, the PLL distributes the transmit waveforms to all antenna elements in the transmit mode and combines the received waveforms in the receive mode without any complicated power distribution network. A spatio-temporal rate-distortion model provides selection of the transcoding parameters during adaptation. Body mounting leg portions provided on the rigid frame are fixed to a seat mounting portion of a vehicle body.
