First Claim
Patent Images
1. A patient support, comprising:
- a frame configured to support a person in at least a horizontal position,a motor,a propulsion device coupled to the motor and coupled to the frame to move the patient support from one location to another location in response to output from the motor,a load cell operable to receive an input from a user and provide a signal based on the input, anda controller coupled to the load cell to receive the signal therefrom, the controller being operable to provide a control signal based on the signal and the second signal and command the motor to operate at a specific output based on the control signal.

9. A patient support, comprising:
-
a frame configured to support a person in at least a horizontal position, a motor, a wheel coupled to the motor and coupled to the frame to move the patient support from one location to another in response to output from the motor, at least one load cell operable to receive a first input from a user and receive a second input from a user and provide at least one signal based on the first and second inputs, a controller coupled to the at least one load cell to receive the at least one signal therefrom, the controller being operable to provide a control signal based on the at least one signal and command the motor to operate at a specific output based on the control signal, a first handle coupled to the at least one load cell, and a second handle coupled to the at least one load cell. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A patient support comprising:
-
a frame configured to support a person in at least a horizontal position, a plurality of casters supporting the frame, a wheel configured to propel the frame, at least one load cell coupled to the frame, the at least one load cell being operable to receive a force and provide a signal based on the force, and a motor operably coupled to the at least one load cell, the motor being operable to drive the wheel in response to the signal, wherein the at least one load cell provides a signal in response to a first state in which a first force is received, the at least one load cell provides a signal in response to a second state in which a second force is received, and in the first state, the signal causes the frame to move in a first direction, and in the second state, the signal causes the frame to move in a second direction different than the first direction. - View Dependent Claims (17, 18, 19, 20)
