Abstract: A control system for a self-propelled patient-support apparatus includes a controller that utilizes a power drive speed control algorithm to control the power output to a motor of a drive mechanism for driving the patient-support apparatus across a floor. The control algorithm normalizes a force input by a user on a user input device, the force indicative of a desired drive speed. The algorithm varies the responsiveness of the output to the drive mechanism based on the current operating conditions of the drive mechanism.

Abstract: A bed includes a frame, a head section coupled to the frame and movable relative to the frame between first and second angular positions, and a sensor operable to determine an angular position of the head section. The sensor is mounted to the head section of the bed at a specified angle. A bed control unit receives signals from the sensor, calibrates the sensor, and monitors the angular position of the head section of the bed relative to gravity.

Abstract: A powered transport device for a person support apparatus includes a floor contacting driver, a prime mover, a power source and a controller. The prime mover is coupled to the driver and an output of the prime mover provides input to the driver. The power source provides power to the prime mover. The controller senses a performance characteristic of the powered transport device and varies the operation of the powered transport device based solely on the performance characteristic.

Abstract: A patient support (10, 14) includes a source of pressurized air (64), a bladder (30), a valve (66) in fluid communication with the source of pressurized air (64) and to the bladder (30), a pressure sensor (28) in fluid communication with the bladder (30), and a controller (26) responsive to a pressure signal from the pressure sensor (28). The controller (26) may determine a rate of change of pressure within the bladder (30) and may store historical pressure data.

Abstract: A patient support including a frame and a mattress supported by the frame. The frame includes a deck support and a deck supporting the mattress.

Abstract: A system for monitoring a patient on a hospital bed includes load cells and a controller for detecting patient movement on, exit from, and impending exit from the hospital bed, including movement across or outside a virtual boundary or region located on the bed. The controller is configured to detect changes in the distribution of patient weight among the load cells. The controller is also configured to accommodate the installation or removal of medical equipment or other tare weights on the bed, head incline adjustment, and bed frame deformation or other changes in the system causing redistribution of weight among the load cells, while minimizing false alarms. A caregiver may select between various patient monitoring modes and remotely monitor patient movement relative to a reference load cell distribution, impending patient exit from the bed and patient exit from the bed. Pressures in an air mattress may be controlled based on signals from the load cells.
