摘要： A method for determining a physiologic characteristic associated with cardiac function in a subject comprising the steps of providing at least one electromagnetic radiation absorption measurement, providing demographic information reflecting the subject's physical condition, determining a temporal plethysmographic value from the electromagnetic radiation absorption measurement, and determining at least one physiologic characteristic from the temporal plethysmographic value and demographic information by using a predetermined phenomenological model that is adapted to provide an estimate of a blood volume-time relationship proximate the heart and compute at least one physiologic characteristic associated with cardiac function based on the estimated blood volume-time relationship.

摘要： A pattern recognition device has a drawing area upon which a user may draw an image with a pen designed for that purpose. In a first option available to the user, a user-drawn image is analyzed and saved in the memory of a computer. In a second option, the image is analyzed and an image in a pre-existing image database of the computer is retrieved which most nearly resembles the drawn image. In both options, the user-drawn image is transformed into a target image which is then subdivided into a plurality of image subdivisions and each image subdivision is then further subdivided into sectors. A first binary value is assigned to each sector to indicate whether or not it has at least some graphical data and a second binary value is assigned to indicate whether or not the graphical data occupies a predetermined percentage of the area of the sector. These binary values are strung together, converted into an integer, and the integers are stored in a computer memory. Since the strung together binary values represent images in compressed numerical form, when the same process is applied to other user-drawn images, the computer can retrieve an image from its memory that most nearly resembles the drawn image by selecting an image in its memory having the nearest numerical value to the drawn image.
摘要翻译：图案识别装置具有绘图区域，用户可以用该画面绘制用于该目的的笔的图像。在用户可用的第一选项中，用户绘制的图像被分析并保存在计算机的存储器中。在第二个选项中，分析图像，并且检索计算机的预先存在的图像数据库中的图像，这几乎与绘制的图像类似。在这两个选项中，用户绘制的图像被转换成目标图像，然后被分割成多个图像细分，并且每个图像细分然后进一步细分成扇区。第一二进制值被分配给每个扇区以指示其是否具有至少一些图形数据，并且分配第二二进制值以指示图形数据是否占据扇区的区域的预定百分比。这些二进制值串在一起，转换为整数，整数存储在计算机内存中。由于串联在一起的二进制值表示压缩数字形式的图像，当将相同的处理应用于其他用户绘制的图像时，计算机可以通过选择其存储器中的图像从其存储器中检索最接近于绘制图像的图像，绘制图像的最接近的数值。
