Abstract
A weight scale for a patient lift system includes a frame assembly. A plurality of force sensors are coupled to the frame assembly. Each of the plurality of force sensors is configured to generate a signal indicative of a measured weight force. A foot rest panel is coupled to the frame assembly. The foot rest panel is configured to support a patient. An angle sensor is operatively coupled to the frame assembly. The angle sensor is configured to generate a signal indicative of an angle of the frame assembly with respect to a horizontal reference plane. A controller is coupled in signal communication with each force sensor and the angle sensor. The controller includes one or more processors configured to receive signals from each force sensor and the angle sensor to determine an actual weight force of the patient.
