A patient support system includes a scale system, an air system, and a lift system. The system comprises vertical mounting posts that include a plurality of spaced openings and a slider track with obliquely angled guide channels. The compact number of bins yields a parameterized latency representation suitable for real-time estimation and goodness-of-fit tests. After assigning the initial bit value, it is determined whether a corresponding portion of the further channel is available for the message. A motion vector detection device includes a first motion vector extraction circuit to extract a predetermined reduced number of first motion vectors from multiple first motion vectors detected by a first motion vector detection circuit, and a selection circuit to select the multiple first motion vectors or the extracted first motion vectors.
