Abstract: The present invention describes an apparatus and method for determining the energy expenditure of a subject by indirect calorimetry where respiratory gases O2 and CO2 are captured in a tent mask coupled through a pneumotach flow meter to a vacuum inlet of a blower fan whose speed is controlled by a computer running a program that ensures that the bias flow being drawn through the mask always exceeds the subject's peak expiratory flow. VO2 and VCO2 and flow values are measured on a breath-by-breath basis and used in arriving at a bias flow adjustment voltage to be applied to the blower fan for adjusting its speed.

Abstract: High centering bases for hospital gurneys are disclosed. An example hospital gurney includes a sensor to detect a position of a lateral rod mechanically coupled to a foot pedal of the hospital gurney by a cross rod and a cam. The hospital gurney additionally comprises an electronically-controlled actuator to move a first wheel based on the detected position, the first wheel located between a first end of the hospital gurney and a second end of the hospital gurney.

Abstract: High centering bases for hospital gurneys are disclosed. An example hospital gurney includes a sensor to detect a position of a foot pedal of the hospital gurney. The example high centering base includes a processor responsive to the sensor to create a movement instruction based on the position of the foot pedal. The example high centering base includes an actuator to move a first wheel based on the movement instruction, the first wheel located between a first end of the hospital gurney and a second end of the hospital gurney.
