    • An automatic calibration system (10) for use with an A/D or D/A converter circuit (12). A reference (18) provides one or more reference signals (20) such that a controller (26) can determine whether the converter circuit (12) is within calibration, and direct a calibration unit (32) to adjust calibration as needed. Sets of calibration values appropriate for differed modes, ranges, and conditions are stored in a memory unit (28), for recall and quick pseudo recalibration. A triggering unit (30), which may optionally be programmable, can then inform the controller (26) when particular events occur. True calibration may then be performed based upon a reference signal (20), or pseudo recalibration may be performed based on calibration values recalled from the memory unit (28). Optionally, the controller (26) may interface with an external system, such as a personal computer having an electronic bus (60), and thus permit external control of both the calibration system (10) and the converter circuit (12).
    • 一种与A / D或D / A转换器电路(12)一起使用的自动校准系统(10)。 参考(18)提供一个或多个参考信号(20),使得控制器(26)可以确定转换器电路(12)是否在校准之内,并且引导校准单元(32)根据需要调整校准。 适用于不同模式,范围和条件的校准值集合存储在存储器单元(28)中,用于调用和快速伪重新校准。 可以可选地可编程的触发单元(30)可以在特定事件发生时通知控制器(26)。 然后可以基于参考信号(20)执行真正校准,或者可以基于从存储器单元(28)回调的校准值来执行伪重新校准。 可选地,控制器(26)可以与诸如具有电子总线(60)的个人计算机的外部系统接口,从而允许校准系统(10)和转换器电路(12)两者的外部控制。

    • A line tensioning system for regulating tension on a line having a proximal end and a distal end, where the proximal end is operatively connected to a drum. The line tensioning system comprises a frame, a first and second sets of rollers, and first and second sets of displacement assemblies. The frame defines first and second side edges. Each first and second displacement assembly is arranged to displace at least one of the first and second rollers relative to the first and second side edges of the frame, respectively. The line is arranged such that the line contacts the first and second rollers. The first and second displacement assemblies displace the first and second rollers relative to the first and second edges based on a tension on the line.
    • 一种用于调节具有近端和远端的线上的张力的线张紧系统,其中近端可操作地连接到鼓。 线张紧系统包括框架,第一和第二组辊以及第一组和第二组位移组件。 框架限定第一和第二侧边缘。 每个第一和第二位移组件被布置成分别相对于框架的第一和第二侧边缘移动第一和第二辊中的至少一个。 线被布置成使得线接触第一和第二辊。 第一和第二位移组件基于线上的张力相对于第一和第二边缘移动第一和第二辊。
