    • A stimulating section (2) applies stimulation to a living body (100). A first lead electrode (3) and a second lead electrode (4) are attached on the living body (100). A first amplifier circuit (5) amplifies potential difference that is evoked between the first lead electrode (3) and the second lead electrode (4) due to the stimulation. A first switch (6) cancels electrical connection between the first amplifier circuit (5) and each of the first lead electrode (3) and the second lead electrode (4) at least while the stimulation is applied. A high-pass filter (7) includes a capacitor (C) and filters a frequency component of an output from the first amplifier circuit (5) that is no less than a predetermined value. A second amplifier circuit (8) amplifies the output from the first amplifier circuit (5). A second switch (10) stops charging/discharging of the capacitor (C) and decreases a gain of the second amplifier circuit (8) at least while the first switch (6) cancels the electrical connection.

    • A system (1) for controlling assistive technologies, provided with at least one assistive tool (2), for users suffering from movement and/or communication disorders, is described. Such a system (1) comprises an electronic communication interface (10), at least one biometric sensor (11), a calibration module (12) and a processing unit (13). The electronic communication interface (10) is configured to present the user with a plurality of sensory stimuli associated with commands and/or pieces of information that the user may want to select and/or to provide. The at least one biometric sensor (11) is adapted to be applied to the user to detect at least one biometric activity of the user and to generate a respective biometric electrical signal (SB, SBc, SBr) representative of the biometric activity detected. The calibration module (12) is configured to record, in an initial system calibration step in which the user's biometric activity is a voluntary biometric activity conventionally considered as indicative of the user's will to respectively select a command and/or a piece of information, one or more signal characteristics CS associated with the biometric electrical signal SBc detected in the presence of said at least one voluntary biometric activity. The processing unit (13) is configured to recognize, based on a comparison between the biometric electrical signal detected SBr and the one or more signal characteristics CS recorded, the voluntary biometric activity of the user and the related command and/or piece of information that the user wants to select, upon a sensory stimulus perceived. The processing unit (13) is also configured to provide control signals (SC1, SC2) both to the electronic communication interface (10) and to the assistive tool (2), based on the recognition of the user's will to select. The electronic communication interface (10) is configured to present the sensory stimuli based on the at least one presentation control signal SC1, if present, and to present an automatic and predefined scan of sensory stimuli, in the absence of the presentation control signal SC1.
    • 描述了用于控制辅助技术的系统(1),其为具有运动和/或通信障碍的用户提供至少一个辅助工具(2)。 这样的系统(1)包括电子通信接口(10),至少一个生物测定传感器(11),校准模块(12)和处理单元(13)。 电子通信接口(10)被配置为向用户呈现与用户可能想要选择和/或提供的命令和/或信息片段相关联的多个感觉刺激。 所述至少一个生物测定传感器(11)适于施加于用户以检测用户的至少一个生物特征活动并产生代表检测到的生物特征活动的相应生物特征电信号(SB,SBc,SBr)。 校准模块(12)被配置为在初始系统校准步骤中记录用户的生物特征活动是常规被认为表示用户分别选择命令和/或一条信息的愿望的自愿生物特征活动 或更多的信号特征CS与在存在所述至少一个自愿生物特征活动的情况下检测到的生物特征电信号SBc相关联。 处理单元(13)被配置为基于检测到的生物特征电信号SBr与所记录的一个或多个信号特征CS之间的比较来识别用户的自愿生物特征活动和相关命令和/或信息片段 用户想要感觉到感觉刺激时选择。 处理单元(13)还被配置为基于对用户的选择意愿的识别来向电子通信接口(10)和辅助工具(2)提供控制信号(SC1,SC2)。 电子通信接口(10)被配置为基于至少一个呈现控制信号SC1(如果存在)呈现感觉刺激,并且在没有呈现控制信号SC1的情况下呈现感觉刺激的自动和预定义的扫描。
