    • A cardiac assist device senses conditions of a heart and controls the generation of various electrical stimuli in response to sense conditions of the heart. The cardiac assist device generates a electrical pulse so as to defibrillate a fibrillated heart when the cardiac assist device determines from the sensed conditions a state of fibrillation. The cardiac assist device generates a chaos control electrical signal so as to bring a pre-fibrillated heart condition back into a normal beating condition when the cardiac assist device determines from the sensed conditions a pre-state of fibrillation. Lastly, the cardiac assist device generates an electrical enhancement signal that causes a threshold of pacing cells in the heart to be exceeded in response to a subthreshold stimulus when the cardiac assist device determines from the sensed conditions a subthreshold pacing signal.
    • 心脏辅助装置感测心脏的状况并响应于心脏的感觉状况来控制各种电刺激的产生。 心脏辅助装置产生电脉冲,以便当心脏辅助装置根据感测到的状态确定原纤化状态时,使原纤化心脏去纤维化。 心脏辅助装置产生混乱控制电信号,以便当心脏辅助装置根据感测到的状态确定原纤化状态时,使预纤维化的心脏状况恢复到正常的跳动状态。 最后,当心脏辅助装置根据感测到的条件确定亚阈值起搏信号时,心脏辅助装置产生响应于亚阈值刺激而导致心脏中起搏细胞阈值的电增强信号。

    • A coherent radiation imaging system that produces digital images with a reduced amount of speckle. Radiation from a long coherence length source is used to form an image of a sample. The output coherent wave is temporally divided into a plurality of wavelets. The spatial phase of each wavelet is then modulated a known and different amount. Each phase modulated wavelet illuminates the sample and is perturbed by its interaction with the sample. A spatial phase map of each perturbed wavelet is then created and converted to a sample image with an image reconstruction program. The plurality of sample images thus formed is statistically averaged to form a final averaged image. The high frequency speckle that is not optically resolvable tends to average to zero with continual statistical averaging, leaving only the optically resolvable lower frequency phase information.
    • 相干辐射成像系统,产生数量少的斑点数字图像。 来自长相干长度源的辐射用于形成样品的图像。 输出相干波在时间上分为多个小波。 然后将每个小波的空间相位调制为已知且不同的量。 每个相位调制小波照亮样品,并受到与样品的相互作用的干扰。 然后创建每个扰动小波的空间相位图,并将其转换为具有图像重建程序的样本图像。 如此形成的多个样本图像被统计学地平均以形成最终平均图像。 不能光学解析的高频散斑趋向于平均为零,并且连续的统计平均,仅留下光学可分辨的较低频率相位信息。
