摘要： A first ultrasound pulse is applied to biological tissue to create shear waves in the biological tissue, a focused ultrasound pulse is transmitted into the biological tissue, one or more ultrasound signals is received from the biological tissue, and shear waves are detected in the biological tissue based on the received one or more ultrasound signals. At least one propagation property associated with the detected shear waves is determined, and the determined at least one propagation property is displayed. A strain image is obtained by either acoustic radiation forces or mechanical compression, e.g., by an ultrasound probe. The strain image is then converted to a new shear wave velocity image by using a previously-obtained shear wave velocity image.

摘要： A maximum flow calculating unit calculates a maximum amount of hydraulic fluid that can flow into or out of an input-side hydraulic cylinder when a shift control command signal is set to a reference DUTY value, based on an estimated valve pressure difference calculated by an estimated pressure difference calculating unit, and a post-guard target sheave position setting unit performs a guard process for restricting the amount of change of the sheave position, using a guard value calculated by a guard value calculating unit based on the maximum flow amount, so as to set a post-guard target sheave position. Since the thus set target sheave position does not undergo excessive large changes nor excessively small changes during shifting, a target value for shifting is set so that a feedforward controlled variable determined based on the amount of change of the target sheave position becomes an appropriate value.

摘要： A controlling system for a vehicle with a continuously variable transmission, which can render a sufficient accelerating feeling in responsive to a driver's requirement. A controller, upon judgment of an acceleration requirement, sets a target drive force higher than the target drive force upon normal calculation upon normal operation of an accelerator pedal, and sets a target rotation speed for acceleration higher than the target rotation speed upon the normal operation and increasing with an increase of the vehicle speed by a predetermined gradient. The speed change ratio of the continuously variable transmission and the output torque of the engine are controlled such that the set target drive force is achieved, and an input shaft rotation speed of the continuously variable transmission coincides with the target rotation speed for the set acceleration. Thus, upon acceleration requirement by the driver, the target drive force increases and the output rotation speed of the drive source increases so that the sufficiently high accelerating feeling from the vehicle can be obtained.

摘要： A powertrain control apparatus controls a powertrain including a lock-up clutch, and an engine, in which fuel supply is cut off, directly to an automatic transmission. The control apparatus includes a control unit that controls the engine so that fuel supply resumes in the engine and a setting unit that sets a hydraulic-pressure instruction value based on a temperature of a combustion chamber of the engine so that a time required to discharge the lock-up clutch is longer when the temperature of the combustion chamber is a first temperature than when the temperature of the combustion chamber is a second temperature which is higher than the first temperature, when the lock-up clutch is controlled to be brought to the disengaged state from the engaged state and the fuel supply to the engine is resumed. The lock-up clutch is then operated by hydraulic pressure corresponding to the hydraulic-pressure instruction value.
