    • Provided is a non-invasive electronic method and apparatus for measuring blood pressure, in which the data is processed with an algorithm of non-linear fitting for recovering trend envelope of an oscillating PW by a firmware, so that the trend envelope of PW amplitude can be recovered accurately, and the obtained average pressure shows higher degree of agreement with the real situation in clinic. In this apparatus, a 3-way solenoid valve (20) is arranged between a cuff (10) and a first pressure sensor (30), wherein the common port of the 3-way solenoid valve (20) is connected with the first pressure sensor (30), the normally open port thereof connected with the cuff (10), and the normally closed port thereof connected with the air atmosphere during zeroing process. Moreover, an independent timing circuit (45) is provided additionally. In the measurement method of the present invention, the zeroing is performed with the help of the 3-way solenoid valve (20). Once a state of overtime or overpressure occurs, a gas pump (50) is immediately closed, and a quick-deflation solenoid valve (60) is opened so that the pressure in the cuff (10) is released to ensure safe application.

    • A method for efficiently optimizing the bin widths for a distribution or an image to be compressed. An image having symmetric uni-modal distribution is divided into a zero bin having a zero bin width and a plurality of outer bins having an outer bin width. M numbers of predetermined candidate values for the zero bin width and N numbers of predetermined candidate values for the outer bin width are provided. A zero bin probability is derived from an entropy function. The allowable zero bin width is calculated from the zero bin probability and target bit rate. The allowable zero bin width is then searched to obtain an optimum combination of the zero bin width and the outer bin width, the optimum combination being the combination having the least distortion measure. In one embodiment, a fast algorithm is used to search the outer bin width for each given zero bin width, reducing the required combination by a factor of logN/N. In one embodiment, the allowable zero bin width is a subset of M number of candidate values for the zero bin width. In one embodiment, the middle number of an interval is used as the quantization value. In another embodiment, the centroid of an interval is used as the quantization value.
    • 一种用于有效地优化分布或待压缩图像的仓宽的方法。 具有对称单模分布的图像被划分为具有零箱宽度的零仓和具有外箱宽度的多个外箱。 提供了用于零仓宽度的M个预定候选值和用于外仓宽度的N个预定候选值的数量。 零斌概率是从熵函数导出的。 从零仓概率和目标比特率计算容许零仓宽度。 然后搜索允许的零仓宽度以获得零仓宽度和外仓宽度的最佳组合,最佳组合是具有最小失真度量的组合。 在一个实施例中,使用快速算法来搜索每个给定零仓宽度的外仓宽度,将所需组合减少一个因子logN / N。 在一个实施例中,容许零仓宽度是零仓宽度的候选值的M个数量的子集。 在一个实施例中,使用间隔的中间数作为量化值。 在另一个实施例中,使用间隔的质心作为量化值。
