    • The present invention relates to devices and methods for providing controlled environments for surgical procedures, as well as transplantation and wound healing. In particular, one embodiment of the present invention provides devices and methods to provide an anaerobic environment for incision sites. In other embodiments, the present invention provides devices and methods to maintain anaerobic conditions during the collection, transport, and implantation of organs, tissues, cells, and other transplant material. In further embodiments, the present invention provides devices and methods for the production and maintenance of an anaerobic environment surrounding sites of trauma or tissue injury. In particular, the present invention provides devices and methods which allow the operator to strictly control the environment for surgical procedures, transplantation and wound healing, etc. Thus, the present invention also finds use in specialized settings where hyperoxic conditions are desireable.

    • A method and apparatus for implementing a new imaging and image composition system based on the real world metaphor of surface absorption, reflection, and transmission where many layers of translucent and opaque objects are composed into a final image for output to a video display. The algorithms are a substitution for both "Painter's algorithm" (the image composition technique traditionally used in computer graphic systems) and the alpha blending algorithms presently used in the computer and television industries for video special effects such as cross-fades between images, transparency, and color keying. In contrast to the prior art "colored pixel" algorithms, this system is based on a light propagation metaphor that uses virtual light source illumination and the absorption, reflection, and transmission properties of the objects in the image to create the final screen image. Thus, instead of representing each picture element (pixel) by color components specified by a chosen color model (e.g., RGB, YUV, Lab, HSV, YIQ, HLS, CMY, CMYK, etc.), the pixels in the subject system are represented by six explicit transformation components (r.sub.1, r.sub.2, r.sub.3, t.sub.1, t.sub.2, t.sub.3) and three implicit transformation components (a.sub.1, a.sub.2, a.sub.3), wherein a, r and t refer to absorption, reflection and transmission, respectively, and the subscripts 1, 2 and 3 refer to the components of the chosen color model.
    • 一种基于表面吸收,反射和透射的真实世界隐喻来实现新的成像和图像合成系统的方法和装置,其中将多层半透明和不透明物体组成最终图像以输出到视频显示器。 这些算法是“Painter的算法”(传统上用于计算机图形系统的图像组合技术)和目前在计算机和电视行业中使用的alpha混合算法的替代,用于视频特殊效果,例如图像之间的交叉淡化,透明度, 和颜色键控。 与现有技术的“彩色像素”算法相比,该系统基于使用虚拟光源照明的光传播隐喻以及图像中对象的吸收,反射和传输属性来创建最终的屏幕图像。 因此,代替通过由所选择的颜色模型(例如,RGB,YUV,Lab,HSV,YIQ,HLS,CMY,CMYK等)指定的颜色成分来表示每个图像元素(像素) 由三个隐式变换分量(a1,a2,a3)表示,其中a,r和t分别表示吸收,反射和透射, 下标1,2和3表示所选颜色模型的组成部分。
