Techniques for determining a pose of a patient transport apparatus

A patient transport apparatus comprising:

• a base;
• a wheel assembly operatively attached to the base and including a wheel arranged for movement along ground surfaces;
• a support frame with a patient support deck defining a patient support surface, the support frame extending longitudinally between a head-end and a foot end;
• a channel formed extending along the support frame between a first end and a second end with a curvilinear portion arranged adjacent to the first end and with a linear portion arranged adjacent to the second end;
• and
• a frame assembly coupled between the support frame and the base, the frame assembly including an actuator, and a slidable member disposed in the channel and movable between a plurality of different positions in the channel to place the support frame in a plurality of different poses relative to the base via operation of the actuator, the plurality of different poses including:
• at least one pose defined with the head-end of the support frame oriented at a first angle relative to the base when the slidable member is disposed along the curvilinear portion of the channel, and
• at least one pose defined with the head-end of the support frame oriented at a second angle, different from the first angle, relative to the base when the slidable member is disposed along the linear portion of the channel.
