    • Embodiments of the present invention are directed toward white light illumination systems (so called “white LEDs”) that comprise a multi-chip excitation source and a phosphor package. In a two-chip source, the two LEDs may be UV-emitting and blue emitting, or blue-emitting and green-emitting. The phosphor package is configured to emit photoluminescence in wavelengths ranging from about 440 nm to about 700 nm upon co-excitation from the first and second radiation sources. The photoluminescence emitted by the phosphors is at least 40 percent of the total power in the white light illumination, and the portion of the total power in the white light illumination contributed by the first and second radiation sources (LEDs) is less than about 60 percent. This ratio can vary in alternative embodiments, and includes 50/50, 60/40, 70/30, and 80/20, respectively. The white light illumination emitted by the system has in one embodiment a color rendering index (CRI) greater than about 90.
    • 本发明的实施例涉及包括多芯片激发源和磷光体封装的白光照明系统(所谓的“白光LED”)。 在双芯片源中,两个LED可以是UV发射和蓝色发射,或发蓝光和绿色发射。 磷光体封装被配置为在从第一和第二辐射源共激发时发射波长为约440nm至约700nm的光致发光。 由荧光体发射的光致发光是白光照射中总功率的至少40%,由第一和第二辐射源(LED)贡献的白光照射中的总功率的部分小于约60% 。 该比例可以在替代实施例中变化,并且分别包括50/50,60 / 40,70 / 30和80/20。 系统发出的白光照明在一个实施例中是显色指数(CRI)大于约90。

    • One embodiment of the present invention provides a system that times commercial offers made to a user. During operation, the system starts by receiving financial history data for the user, wherein the financial history data includes purchase records for a set of purchases. The system then identifies a subset of purchases in the set of purchases, wherein the subset of purchases are semantically linked to a set of predetermined subjects. Next, the system identifies timing patterns in the subset of purchases based on timing information associated with the subset of purchases. The system then presents one or more commercial offers to the user at specific times based on the identified timing patterns.
    • 本发明的一个实施例提供了一种对用户进行商业提供的系统。 在操作期间,系统通过接收用户的财务历史数据开始,其中财务历史数据包括一组购买的购买记录。 系统然后识别购买集合中的购买子集,其中购买子集语义地链接到一组预定主体。 接下来,系统基于与购买子集相关联的定时信息来识别购买子集中的时间模式。 然后,系统基于所识别的定时模式,在特定时间向用户呈现一个或多个商业报价。

    • A medical image compression and decompression technique is presented which exploits the special characteristics of medical images so as to increase the achievable compression ratio over existing generic image compression techniques. In general, the presented technique categorizes medical images based on the type of images. Medical images within the same category will typically have a very high level of similarity to each other. For each category, a type of standard image is computed which represents the typical characteristics of images within a category. For each image being compressed, only the difference between the image and the standard image is compressed. Due to the high level of similarity between images in the same category, the aforementioned difference is typically small and therefore a high compression ratio can be achieved.
    • 提出了一种医学图像压缩和解压缩技术,它利用了医学图像的特殊特征,从而提高了现有通用图像压缩技术可实现的压缩比。 一般来说,所提出的技术基于图像的类型对医学图像进行分类。 相同类别内的医学图像通常具有相当高的相似度。 对于每个类别,计算一种类型的标准图像,其表示类别内的图像的典型特征。 对于被压缩的每个图像,仅压缩图像和标准图像之间的差异。 由于相同类别的图像之间的高度相似性,上述差异通常很小,因此可以实现高压缩比。
