摘要： A method of a mobile station receiving data packets from a serving base station via a multicast or broadcast connection in a wireless network is provided for performing a handover from the serving base station to a target base station. The method comprises, at the level of the mobile station, the steps of: upon the detection of the quantity of buffered data packets in the mobile station being lower than a first threshold value, establishing a unicast connection with the serving base station to receive data packets from the serving base station; and upon detection of the level of buffered data packets reaching the predetermined threshold level, performing a handover from the serving base station to the target base station. According to the invention, a seamless handover of a mobile station in a wireless network providing Multicast and Broadcast Service (MBS service) can be achieved to prevent the MBS service interruption during the handover.

摘要： A wireless transmission scheme for transmitting images utilizing a cross layer method integrated the slice allocation and multiple modulation and coding modes selection without the need of feedback channel. The scheme divides a coded image into isolated coded slices, wherein each slice represents a region of the image and each slice is then modulated using modulation schemes of differing robustness. Data of most interest is received by all receivers, with some receivers receiving more data in areas with good channel conditions.

摘要： An alternating scheduling algorithm is useful in a mesh network. Transmissions are scheduled along a branch in a tree structure such that simultaneous transmissions occur only in non-adjacent layers along the branch. In a disclosed example, every other layer is grouped into a set of layers such that the sets are mutually exclusive and the sets only include non-adjacent layers. One example includes designating one set of layers as the even layers and another set as odd layers. A scheduler schedules transmissions on the layers such that simultaneous transmissions along a branch occur only on layers within one of the sets while transmissions on the other set along the same branch are prevented. The sets of layers selected for transmission are alternated each subsequent scheduling window or frame.

Because of the unique construction the device will give accurate reading if temporarily immersed in the specimen or left in the specimen for an extended period of time, making it very user friendly.

摘要： Medical imaging uses cyclical motion analysis. Phase and/or amplitude analysis of variation for spatial locations in a sequence of images over one or more heart cycles is performed. For phase analysis, selected phase information is cyclically isolated as a function of the heart cycle. For example, a sequence of three images is associated with three different times during the heart cycle. In one image, phases over one range are highlighted. In subsequent images, phases over different ranges are highlighted. By showing the sequence of images in a loop with the shifting phase throughout the sequence, wall contractions are easily visualized. For amplitude analysis, information associated with a selected frequency band, such as the constant and fundamental frequency bands, are isolated. Images are then generated in response to the isolated information. The images have reduced speckle content due to the lack of higher order frequency information. Some higher order frequency information may be allowed to remain or added to avoid motion blurring. The isolated information also more likely has well defined borders or edges as compared to the information with the full bandwidth.
摘要翻译：医学成像使用周期运动分析。执行在一个或多个心脏周期上的图像序列中的空间位置的变化的相位和/或幅度分析。对于相位分析，选择的相位信息是循环隔离的，作为心脏周期的函数。例如，在心脏周期中，三个图像的序列与三个不同的时间相关联。在一个图像中，突出显示一个范围上的相位。在后续图像中，突出显示不同范围的相位。通过在整个序列中显示具有移动阶段的循环中的图像序列，壁收缩容易可视化。对于振幅分析，与所选频带（例如恒定频带和基频带）相关联的信息被隔离。然后响应于隔离信息生成图像。由于缺乏更高阶的频率信息，图像减少了斑点内容。可以允许一些更高阶的频率信息保留或添加以避免运动模糊。与具有全部带宽的信息相比，孤立的信息更有可能具有明确的边界或边缘。

摘要： Three or four-dimensional ultrasound data acquisition for extended field of view imaging is provided. Multiple volumes are registered with respect to each other and spliced together to form an extended volume. The extended volume is a contiguous volume larger than a volumetric region that a multi-dimensional or wobbler transducer array is capable of imaging without movement. Information representing different volumes is registered with respect to each other by sensing the transducer position associated with each of the different volumes. The position is sensed using a position sensing mechanism, such as magnetic optical or gyroscope measurements. Acoustic data may be used to determine decorrelation of speckle or correlation of features to sense position. After the volumes are registered, any overlapping regions are compounded. The resulting extended field of view volume is displayed and manipulated for viewing by the user. A large volume or extended volume of the patient is used for assessing an organ, such as an entire fetus in OB applications.

摘要： Method of dynamically measuring movement of objects is disclosed which uses image processing. In a first step a sequence of images is received and stored. Then, at least a first and second reference point within a first image is determined and identification areas around those reference points are defined. Within a sequential image a search area around the predefined reference points which best match the identification area is searched to determine the displacement of the reference point.
