A system includes a viewer sensor that generates sensor data for sensing one or more viewers of a video display device. Among the features are fully adjustable and retractable siderails, bed raise-and-lower features, head-up and leg-down features for converting to a seated position, as well as Trendelenburg and reverse-Trendelenburg features. The first computer is operated by the statement provider and the second is operated by a clerk associated with the statement receiver. On the other hand, the guide rod further includes a guide groove slideably mated with a corresponding guide rib of an insulating housing, which make the slider slide reliably in a front-to-back direction.
