    • A bleed air valve system is provided that includes a housing, a piston, a cap, a poppet, a first guide ring, and a second guide ring. The housing includes an upper valve seat extending radially inwardly therefrom. The piston is located at least partially in the housing. The cap is coupled to the housing and includes an annular axial section located therein and a lower valve seat. The poppet is located at least partially within the housing and includes a piston coupling section, a valve body section having an upper valve seat contact surface and a lower valve seat contact surface extending radially outwardly therefrom, and a guide section extending through the cap annular axial section. One guide rings is coupled to the piston to contact the housing inner surface. Another guide ring is coupled to the poppet guide section and contacts the cap annular axial section.
    • 提供一种排气阀系统,其包括壳体,活塞,盖,提升阀,第一导向环和第二导向环。 壳体包括从其径向向内延伸的上阀座。 活塞至少部分地位于壳体中。 盖子联接到壳体并且包括位于其中的环形轴向部分和下部阀座。 提升阀至少部分地位于壳体内,并且包括活塞连接部分,具有上阀座接触表面的阀体部分和从其径向向外延伸的下阀座接触表面,以及引导部分,其延伸穿过盖环形轴向 部分。 一个引导环联接到活塞以接触壳体内表面。 另一引导环联接到提升引导部分并接触盖环形轴向部分。

    • A method of analyzing EEG and EP data in order to differentiate between ongoing neuro-electric activity of the brain of a subject and evoked neuro-electric activity of the brain of the subject, the analysis being based upon the frequency and the amplitude of deflections from the base line of the EEG and EP data, the method including a. recording by EEG measurement the ongoing neuro-electric activity; b. administering a series of sensory stimuli to the subject; c. recording by EEG and EP measurement neuro-electric activity evoked in response to the stimuli; d. marking the time of occurrence, polarity and amplitude of each of the deflections recorded; e. generating a histogram of time periods of the deflections for a defined duration prior to, during and subsequent to each of the single stimuli, the histogram reflecting the deflections within the time periods, generating a deflection time distribution based upon data from the histogram, generating an amplitude profile of the deflections, and f using the deflection time distribution and the amplitude profile to statistically analyze and evaluate the ongoing and evoked neuro-electric activity; such that the differentiation between the ongoing and the evoked neuro-electric activity may be quantified.
    • 一种分析EEG和EP数据的方法,以区分受试者的脑的正在进行的神经电活动和受试者的大脑的诱发的神经电活动,该分析基于频率和来自 EEG和EP数据的基线,方法包括a。 通过EEG测量记录正在进行的神经电活动; b。 对受试者施用一系列感觉刺激物; C。 通过EEG记录和EP测量响应刺激诱发的神经电活动; d。 标记出现的每个偏差发生的时间,极性和幅度; e。 在每个单个刺激之前,期间和之后,在反映在该时间段内的偏转的直方图之前,产生偏转时间分布,基于来自直方图的数据产生偏转时间分布,生成 使用偏转时间分布和振幅分布来统计分析和评估正在进行的和诱发的神经电活动; 使得正在进行的和诱发的神经电活动之间的区分可以被量化。
