10. A method of sealing a patient’s trachea comprising:
wherein at least a portion of the tapered section is adapted to form a wrinkle-free sealing band against a patient’s tracheal wall and adjacent to the wrinkle-free sealing band when the balloon cuff is inflated to an intracuff pressure of 10-30 cm H2O;
and wherein at least a portion of the tapered section is adapted to form a wrinkled band against the tracheal wall, wherein the wrinkled band is longer than the wrinkle-free sealing band when the balloon cuff is inflated within the trachea.
11. The method of claim 10, wherein the wrinkled band is disposed on the cuff proximally of the wrinkle-free sealing band.
12. The inflatable method of claim 10, wherein the wrinkle-free sealing band is formed when the balloon cuff is inflated to an intracuff pressure of 20-25 cm H2O.

1. An engine measuring equipment for measuring engine performance in bench tests implemented with an engine and a dynamometer connected to the engine, the engine measuring equipment comprising:
a central control unit for controlling throttle opening degrees due to revolution of the engine and load torque of the dynamometer;
a detector connected to an output shaft of the engine, for detecting measurement data including at least revolution and shaft torque of the engine driven by controlling the central control unit; and
a signal processing unit for measuring engine torque based on measurement data from the detector,
wherein the central control unit implements such controlling that the revolution is lead to a transient state, and wherein the shaft torque varies during a period of the transient state; and
wherein the signal processing unit calculates the engine torque based on time series data of the revolution and the shaft torque detected with the detector to measure engine torque from transient state data.
2. The engine measuring equipment according to claim 1, wherein the engine torque is calculated by performing computing process including time differentiation of the time series data of the revolution andor shaft torque.
3. The engine measuring equipment according to claim 1 or 2, wherein the central control unit performs control operation so that the load torque is increased or decreased sequentially by each predetermined value while the throttle opening degrees changes for at least one cycle from the minimum value to the maximum value at each step of the predetermined value.
4. The engine measure equipment according to claim 1 or 2, further comprising a display unit for displaying characteristics of relationship between the engine torque and the revolution.
5. The engine measuring equipment according to claim 1 or 2, further comprising an assessing unit for implementing validity assessment on the test conditions andor reliability assessment on the measurement data, andor effectiveness assessment on the correction data and engine torque calculated on the basis of the measurement data.
