    Abstract: In a variable torque rate test joint, screw-threaded first and second elements are rotated relative to one another by a tool under test. At least one spring beam is cantilevered over a pivot point to exert an axial force between the first and second elements and the torque rate of the test joint can be varied by moving the pivot point to change the axial force. The first element may be a shaft that is fixed during testing and the second element is a nut rotatably mounted on the shaft, whereby the element rotated by the tool has a minimal moment of inertia. Whichever of the first and second elements is held stationary during the test may be mounted in a hub that is locked during the test but can be rotated at the end of the test to reset the test joint. Measurements may be made of the torque and the rotation angle to derive an actual torque rate of the joint, which allows correction of errors by moving the pivot point.

    Abstract: A method of controlling a gas delivery apparatus including an apparatus controllable variable using an iterative algorithm to deliver a test gas (TG) for non-invasively determining a subject's pulmonary blood flow comprising iteratively generating and evaluating test values of a iterated variable based on an iterative algorithm in order output a test value of the iterated variable that meets a test criterion wherein iterative algorithm is characterized in that it defines a test mathematical relationship between the at least one apparatus controllable variable, the iterated variable and an end tidal concentration of test gas attained by setting the apparatus controllable variable, such that the iterative algorithm is determinative of whether iteration on the test value satisfies a test criterion or iteratively generates a progressively refined test value.

    Abstract: A method and apparatus for evaluating the relative contribution of the diaphragm versus other thoracic muscles to breathing by obtaining measurements of parameters that correlate with changes in thoracic cavity and intra-abdominal cavity pressures over identical time increments and organizing the measurement data in manner that reveals whether the pressures changes are characteristic of the pattern of contemporaneous pressure changes in those cavities that accompany contraction and/or relaxation of the diaphragm muscles or whether the pressure changes are characteristic of the pattern of contemporaneous pressure changes in those cavities that accompany contraction and/or relaxation of the intercostal muscles.
