Claim Text:
1. An apparatus for supporting a patient, the apparatus comprising: a base; a frame to support the patient above the base; a lift coupled to the base and the frame by pivotable connections, the lift being operable to elevate a first end of the frame relative to a second end of the frame; a force sensor coupled to the frame, the force sensor being configured to generate a force signal in response to a detected force; a first angle sensor coupled to the frame, the first angle sensor being configured to generate a first angle signal representative of an angle of the force sensor, wherein the first angle sensor is spaced from the pivotable connections between the lift and the frame; a second angle sensor coupled to the base, the second angle sensor being configured to generate a second angle signal representative of an amount that the base is tilted; a controller coupled to the first and second angle sensors to receive the respective first and second angle signals therefrom and coupled to the force sensor to receive the force signal therefrom, the controller being configured to calculate a weight of the patient based on the first and second angle signals and the force signal; and an output device coupled to the controller and configured to indicate the weight of the patient.
