  • Publication number: 20170307070
    Abstract: The present disclosure relates to a method for controlling a lock-up clutch of an automatic transmission. The method includes: a detecting step of detecting, by a controller, a current signal applied to a solenoid valve of an engaging element when a gear change operation begins; and a first increasing control step of controlling, by the controller, an amount of current that is applied to a solenoid valve of a lock-up clutch during an initial fill time period when it is determined that the current signal is applied to the solenoid valve of the engaging element. In particular, the solenoid valve of the engaging element is used to form a gear stage, and the controller increases the amount of current to a predetermined level for a predetermined period of time.

  • Patent number: 9664764
    Abstract: An MRI system acquires a susceptibility-weighted image by acquiring a first RF echo signal in a first echo time for providing an image exclusive of susceptibility-weighting and acquiring a second RF echo signal in a second echo time longer than the first echo time for providing an image including susceptibility-weighting. A compensation gradient field is applied for compensating for field inhomogeneity and in response, a third RF echo signal is acquired in a third echo time longer than the second echo time. First, second and third images are generated in response to data derived from the first, second and third RF echo signals respectively and data of the first, second and third images is combined to provide image data representing an image compensating for magnetic resonance signal attenuation in the second image.
