    • An electronic digital controller, such as a load cell indicator, is disclosed in which a number of components, such as a circuit board, display, and keypad are placed within an enclosure, and the enclosure is bonded closed, such as using an adhesive, to render the enclosure watertight. The keypad is a touch sensitive, capacitive keypad with no moving parts, and it is housed behind a rigid panel. An optoelectronic transceiver allows for data exchange with an electronic memory device housed in the adhesively sealed enclosure and allows for data exchange and for updating or modification of software code housed therein. Other components, such as another circuit board, a power supply, and block connectors, are placed in an adjacent enclosure, and the circuit boards in the two enclosures are electrically connected. The power supply is preferably a potted AC power supply but may also include a battery.

    • A method for detecting perturbation of a physical system from a reference state associated with a reference parameter (ω0) to a perturbed state associated with a perturbed parameter (ω) includes firstly deriving the reference parameter (ω0). A reference vector (F) is then derived which describes the system's state at the reference parameter (ω0). A measurement-related vector (Z) associated with a perturbed state of the system is then subtracted from the reference vector (F) to provide an error vector (E). The error vector members are summed and normalised by division of a summation of elements of a vector (F′) representing a derivative (f(ω0δω)e) of a reference itself represented by the reference vector (F), the derivative (f(ω0δω)e) being evaluated at the reference parameter (ω0). This provides a result equal to the difference (ω-(ω0) between the perturbed parameter (ω) and the reference parameter (ω0).
    • 用于检测物理系统与参考参数(ω= 0)相关联的参考状态的扰动到与扰动参数(ω)相关联的扰动状态的方法包括首先导出参考参数(ω, SUB> 0 )。 然后导出参考矢量(F),其描述参考参数(Ω-0> 0)处的系统状态。 然后从参考矢量(F)中减去与系统的扰动状态相关联的测量相关矢量(Z)以提供误差向量(E)。 误差向量成员被加法和归一化,该方法是通过表示一个向量(F')的元素的和(F(ω) 参考自身由参考矢量(F)表示,在参考参数(ω= 0)处评估的导数(f(ω,Δδ,Δomega) SUB>)。 这提供了等于扰动参数(ω)和参考参数(ω= 0 <0>)之间的差值(ω-ωω)的结果。
