Abstract:
1. A patient support apparatus comprising a lower frame, an upper frame movable relative to the lower frame, a first sensor positioned on one of the upper frame and the lower frame, the sensor having a sensing field and transmitting a signal when the first sensor detects a body in the sensing field; and a control system including a controller coordinating movement of the upper frame relative to the lower frame, the controller receiving a signal from the first sensor and responding to the first sensor to control movement of the upper frame by changing the speed at which the upper frame moves relative to the lower frame-by varying the speed of one or more drives until the obstruction is no longer detected wherein the patient support apparatus further comprises a patient support deck section supported on the upper frame and a second sensor positioned on the patient support deck, the patient support deck section movable relative to the upper frame, wherein the controller modifies the movement of the upper frame relative to the lower frame if movement of the upper frame is being requested and the first sensor detects a body in the sensing field, wherein the controller modifies the movement of the patient support deck section relative to the upper frame if movement of the patient support deck section is being requested and the second sensor detects a body in the sensing field.
