Abstract: A patient support including a traction device for powered movement of the patient support.

Abstract: A patient support apparatus has a powered transport device that is operable to propel the apparatus along a floor in forward and reverse longitudinal directions, as well as in left and right lateral directions. A user input for selection of discrete speed settings for the powered transport device is included on the patient support apparatus. User inputs for controlling the direction that the apparatus is propelled are provided at the head end, foot end, and both sides of the patient support apparatus.

Abstract: A system and method are disclosed for automatically refreshing a dynamic random access memory (DRAM) under a plurality of different operational conditions of an associated processor. When the processor is normally executing instructions it generates active signals which enable a generator circuit to generate timing signals. A hidden refresh circuit uses status signals and a first part of these timing signals to generate a refresh pulse during an opcode fetch cycle of each instruction being executed by the processor. A control circuit uses each refresh pulse and a second part of the timing signals to generate a row refresh signal to refresh a row in the DRAM indicated by a row address from a counter and a row address clock to increment the counter to the next row to be refreshed by the following row refresh signal.
