    • Real-time control of a prosthetic device using EMG-based locomotion state classification computes a histogram [208] of a time-frequency spectrogram [206] of the EMG data [200] sampled from muscles, classifies the histogram using if-else rules [212] as representing a locomotion steady state [216] or locomotion transition state [214] in the prosthetic device, and controls the prosthetic device using the computed transitions between locomotion modes. The classification may be based on a comparison of feature values [210] derived from the histogram and stored feature values derived from histograms of known locomotion states. Alternatively, the classification may be based on matching scores calculated from the histogram and stored histograms of known locomotion states. The classifying preferably is performed using hierarchical if-else fuzzy classification rules [212], and may further include using a prior locomotion state and a state diagram specifying constraints on locomotion states accessible from other locomotion states.
    • 使用基于EMG的运动状态分类的假体装置的实时控制计算从肌肉采样的EMG数据[200]的时间频谱图[206]的直方图[208],使用if-else规则对直方图进行分类[ 212]表示假体装置中的运动稳定状态[216]或运动过渡状态[214],并且使用所计算的运动模式之间的转换来控制假体装置。 分类可以基于从直方图导出的特征值[210]与从已知运动状态的直方图导出的存储的特征值的比较。 或者,分类可以基于从直方图计算的匹配分数和存储的已知运动状态的直方图。 分类优选地使用分层的if-else模糊分类规则[212]来执行,并且还可以包括使用先前的运动状态和指定从其他运动状态可访问的运动状态的约束的状态图。

    • Particular aspects provide methods for converting glucosinolate in a glucosinolate- containing plant material to glucosinolate breakdown products (GBPs), comprising: providing an amount of processed glucosinolate-containing plant material, the processed material being depleted of oil and glucosinolate converting enzyme activity by virtue of said processing; providing an amount of glucosinolate converting enzyme activity; mixing the processed material with the amount enzyme activity; hydrating the mixture; and incubating the hydrated mixture, wherein the glucosinolates are enzymatically converted to GBPs. Preferably, the processed plant material comprises a oilseed-derived seedmeal material (e.g., meadowfoam seedmeal) from which the oil has been removed by the processing (e.g., solvent extraction and/or heat treatment). In particular embodiments, the glucosinolate converting enzyme activity comprises at least one of a myrosinase activity and a nitrile-forming activity. Additional aspects provide low-fat compositions (e.g., herbicide, fungicide, insecticide, bacteriostatic or bactericidal, cosmetic, cosmeceutical or pharmaceutical) comprising GBPs derived from a glucosinolate-containing plant material.
