    • Apparatus, systems, and methods to control the frequency of a plurality of gyroscopes are disclosed. The gyroscopes are configured such that each individual gyroscope operates independently of one another and at the same pre-determined frequency. To accomplish this, the natural frequency of each gyroscope is determined, and a reference signal is added to the output signal of its respective gyroscope such that the sum of the natural frequency and the reference signal frequency equals the pre-determined frequency. Thus, each individual gyroscope, though it may include its own individual natural frequency, operates autonomously at the pre-determined frequency.
    • 公开了用于控制多个陀螺仪的频率的装置,系统和方法。 陀螺仪配置成使得每个单独的陀螺仪彼此独立地并且以相同的预定频率运行。 为了实现这一点,确定每个陀螺仪的固有频率,并且将参考信号添加到其各自陀螺仪的输出信号,使得固有频率和参考信号频率之和等于预定频率。 因此,每个单独的陀螺仪虽然可以包括其自己的单独的固有频率,但是以预定的频率自主地运行。

    • An image processing system and method visually documents and displays changes between historical and later mammographic images, preferably in three dimensions. A composite image is created which visually emphasizes temporal differences between the historical and later images. Preferably three-dimensional, digitized images, displayable in various projections, are stored for archival purposes on computer readable media. An image processor preferably exploits an optical correlator to register the historical and later images accurately and provide correlation values as temporal scalars of the differences. The registered images are then compared, voxel-by-voxel, to detect temporal differences. The composite image is displayed with synthetic colors or other visual clues to emphasize apparent changes (for example, tumor growth or shrinkage).
    • 图像处理系统和方法可视地记录和显示历史和以后的乳房照相图像之间的改变,优选地在三维中。 创建合成图像,其视觉上强调历史和稍后图像之间的时间差异。 优选地,可显示在各种投影中的三维数字化图像被存储用于存储在计算机可读介质上的目的。 图像处理器优选地利用光相关器来准确地登记历史和后期图像,并且将相关值作为差值的时间标量提供。 然后将注册的图像与体元体素进行比较,以检测时间差异。 复合图像用合成颜色或其他视觉线索显示,以强调明显的变化(例如肿瘤生长或收缩)。
