    Abstract: An apparatus and method are provided for monitoring an antenna state of a mobile station. A resister may be provided between a battery voltage terminal and a power source voltage terminal of a power amplifier. A voltage level corresponding to a dropped amount of a voltage due to the resister may be generated and compared with a previously stored voltage level to determine whether current consumption of the power amplifier has been increased. If the increased amount of the current consumption of the power amplifier is large, the currently connected antenna may be determined to be in an abnormal state and a transmission path may be switched to another antenna. If two antennas provided in the mobile communication are in an electrically abnormal state, a baseband chip may inform a user of the abnormal state of the antenna. Accordingly, an output level degradation generated when the antenna is operated in an electrically abnormal state and shortening of the life span of a battery can be prevented. Thus, performance of an output terminal can be enhanced.

    Abstract: A method for automatically evaluating image data taking over a sequence of image frames to determine a contour of a left ventricle (LV). The sequence of image frames are converted to digital data that identify a gray scale value for each pixel in each image frame. Using probability, an initial LV region is estimated based upon previously determined a priori parameters that are derived from processing manually drawn contours of the LV in other hearts, for the sequence of image frames being analyzed. The initial estimate of the LV region is refined using motion constraints, which are also derived from training data determined from the manually-drawn contours of other hearts. An LV region is estimated and its coordinates are extracted for use in applying global shape constraints that provide a more accurate LV boundary estimate for the region around an apex of the left ventricle. Finally, the estimated LV boundary estimate is tested for consistency, yielding an accepted estimate, or warning that the estimate is unreliable. The resulting automatically determined contours of each image frame can be displayed almost immediately after the image data are produced so that a physician can more readily diagnose physiological defects of the heart.
