    • A design and a fabrication method for an intravascular imaging and therapeutic catheters for combined ultrasound, photoacoustic, and elasticity imaging and for optical and/or acoustic therapy of hollow organs and diseased blood vessels and tissues are disclosed in the present invention. The invention comprises both a device—optical fiber-based intravascular catheter designs for combined IVUS/IVPA, and elasticity imaging and for acoustic and/or optical therapy—and a method of combined ultrasound, photoacoustic, and elasticity imaging and optical and/or acoustic therapy. The designs of the catheters are based on single-element catheter-based ultrasound transducers or on ultrasound array-based units coupled with optical fiber, fiber bundles or a combination thereof with specially designed light delivery systems. One approach uses the side fire fiber, similar to the one utilized for biomedical optical spectroscopy. The second catheter design uses the micro-optics in the manner of a probe for optical coherent tomography.

    • Techniques are provided for reducing signal congestion in programmable logic devices (PLDs). In one example, a computer-implemented method of reducing signal congestion in a configuration of a PLD includes mapping a plurality of circuit components of a circuit design to a plurality of components of the PLD, wherein each of the mapped PLD components is associated with one of a plurality of regions of the PLD and with one or more unique signal paths entering the PLD region. The method also includes determining a cost value for each PLD region based at least in part on the number of unique signal paths entering the PLD region from other PLD regions. The method also includes selecting one of the PLD components to move from a first one of the PLD regions to a second one of the PLD regions. The method also includes updating the cost values associated with the first and second PLD regions based on a change in the number of unique signal paths entering the first and second PLD regions. The method also includes selectively accepting or rejecting the move based at least in part on the updated cost values.
    • 提供了用于减少可编程逻辑器件(PLD)中的信号拥塞的技术。 在一个示例中,减少PLD的配置中的信号拥塞的计算机实现的方法包括将电路设计的多个电路组件映射到PLD的多个组件,其中映射的PLD组件中的每一个与一个 的PLD的多个区域以及进入PLD区域的一个或多个唯一信号路径。 该方法还包括至少部分地基于从其它PLD区域进入PLD区域的唯一信号路径的数量来确定每个PLD区域的成本值。 该方法还包括选择一个PLD分量以从PLD区域中的第一个PLD区域移动到第二个PLD区域。 该方法还包括基于进入第一和第二PLD区域的唯一信号路径的数量的变化来更新与第一和第二PLD区域相关联的成本值。 该方法还包括至少部分地基于更新的成本值选择性地接受或拒绝移动。
