    • A defibrillator system includes an implantable defibrillator and a non-implantable external receiver. The implantable defibrillator includes a first sense channel for generating a first electrogram and a second sense channel for generating a second electrogram. The defibrillator further includes a cardioverter for applying cardioverting electrical energy to the heart and a transmitter for transmitting the first and second electrograms. The non-implantable receiver includes a display for simultaneously displaying the first and second electrograms. The implantable defibrillator may further include an event detector having a threshold for detecting cardiac events in one of the electrograms and an event marker generator for generating an event marker for each detected cardiac event. The transmitter transmits the event detection markers and the display displays the event detection markers and the thresholds with the corresponding electrogram.
    • 除颤器系统包括可植入除颤器和不可植入的外部接收器。 可植入除颤器包括用于产生第一电描记图的第一感测通道和用于产生第二电描记图的第二感测通道。 除颤器还包括用于向心脏施加心脏转复电能的心律转复器,以及用于发送第一和第二电描记图的发射器。 非植入式接收器包括用于同时显示第一和第二电描记图的显示器。 可植入除颤器还可以包括事件检测器,该事件检测器具有用于检测其中一个电描记图中的心脏事件的阈值和用于为每个检测到的心脏事件产生事件标记的事件标记发生器。 发射机发送事件检测标记,显示屏显示事件检测标记和阈值与相应的电描记图。

    • Methods and systems are provided that combine Dambrackas Video Compression (DVC) with block video compression. When transmitting video frames that are changing, they determine which blocks have changed from frame to frame and transmit the information for the blocks that have changed. They apply DVC compression to the blocks that have changed, reducing the amount of data to be transmitted from frame to frame. Information regarding the blocks that have changed may be the only information transmitted, and the information transmitted in the changed blocks is compressed using DVC commands. These methods and systems may realize a combined benefit of block compression systems and DVC systems. These systems provide a way to enhance DVC so that only blocks of video data that have changed are encoded and compressed and thus fewer bytes of data will be sent to the client.
    • 提供了将Dambrackas视频压缩(DVC)与块视频压缩相结合的方法和系统。 当发送正在变化的视频帧时,它们确定哪些块已经从帧到帧改变,并且发送已经改变的块的信息。 它们对已经改变的块应用DVC压缩,从而减少要从帧到帧传输的数据量。 关于已经改变的块的信息可以是发送的唯一信息,并且使用DVC命令来压缩在改变的块中发送的信息。 这些方法和系统可以实现块压缩系统和DVC系统的组合益处。 这些系统提供了一种增强DVC的方法,使得只有已经改变的视频数据块被编码和压缩,并且因此将更少的数据字节发送到客户端。
