    Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

    Abstract: A patient support apparatus includes a pedal assembly for selecting between a first state and a second state different from the first state, and comprising first and second pedals. The first and second pedals are configured to pivot together in a first rotational direction relative to a respective pivot axis to transition from the first state to the second state, and the first and second pedals are configured to pivot together in a second rotational direction opposite the first rotational direction to transition from the second state to the first state. At least a distal portion of the first pedal is configured to pivot independently from the second pedal in the first rotational direction when in the first state, and at least a distal portion of the second pedal is configured to pivot independently from the first pedal in the second rotational direction when in the second state.

    Abstract: Systems, methods and techniques for operating a patient support apparatus are disclosed. The patient support apparatus includes a support structure including a base and a patient support surface to support a patient. The patient support apparatus also includes an actuator coupled to the support structure and operable to move the patient support surface. The actuator is configured to receive an applied voltage and an applied electrical current, and to produce an output power, where the applied electrical current varies based on different loads applied to the actuator. A controller is coupled to the actuator to determine a desired output power of the actuator and to control the actuator such that the output power produced by the actuator is controlled relative to the desired output power by modifying the applied voltage to compensate for the different loads being applied to the actuator.

    Abstract: A patient support apparatus includes a base having a length and including a plurality of caster wheels enabling movement of the patient support apparatus across a floor surface. An auxiliary wheel support structure is secured to the base and rotatably supports at least one non-castered auxiliary wheel. A drive mechanism including a motor may be configured to drive the auxiliary wheel. A braking system including at least one brake member may be configured to apply a braking force to decelerate the auxiliary wheel and is movable between a first position wherein the at least one brake member is disengaged from the auxiliary wheel and a deployed position wherein the at least one brake member is frictionally engaged with the auxiliary wheel to restrict rotation of the auxiliary wheel. The braking system may be configured to synchronize the braking forces applied to first and second auxiliary wheels.

    Abstract: A chair includes a seat, a backrest, and a leg rest. A tilt actuator and lift actuator tilt and lift the seat, respectively. A leg rest actuator extends and retracts the leg rest. A backrest actuator pivots the backrest with respect to the seat. A controller simultaneously controls the actuators such that they move sequentially between multiple predefined states. A control panel enables a user to automatically move the chair to any of the predefined states. A controller controls the actuators such that they simultaneously arrive at each state. One or more functions on a control panel may also be automatically disabled and/or automatically enabled as the chair moves into or out of certain ones of the predefined states. When transitioning between some states, all of the actuators are activated, and when transitioning between other states, only a subset of the actuators is activated.
