Abstract: A system and method for sending a multi-channel PCM audio stream over a link. An encoder combines a plurality of individual PCM audio channels into a multi-channel audio stream and encodes the multi-channel audio stream to maintain channel order, wherein encoding includes using a bit of one of the encoded channels to mark the encoded channel as a first channel. A transmitter transmits the encoded multi-channel audio stream over the link. A receiver receives the transmitted and encoded multi-channel audio stream and recovers the encoded multi-channel audio stream and one or more clocks. A decoder locates the first channel and de-interleaves the multiple audio streams into individual PCM-encoded audio channels, wherein locating includes looking for the bit that marks the first channel.

Abstract: A portable device is provided that is used to warm a mammography machine and which comprises a warmer and a holder for the warmer, the holder having a charging mechanism for charging the warmer. The warmer includes an enclosed heating element and power source. The heating element is precisely regulated to ensure that the sensitive imaging elements are not damaged by an over-temperature condition, while at the same time permitting a rapid heating of the warmer for high cycle use. The warmer warms surfaces of the mammography machine that contacts human skin.
