摘要： A redundant computer system utilizing comparison diagnostics and voting techniques includes a plurality of redundant channels. Each pair of the processors receives/obtains process information from I/O modules via dual redundant sensors (DRS). The processors execute an application program, whereby output module is utilized for comparing output data of the two processors. Output module receives output data from neighboring modules, if there is a deviation or other disparity in the output data. Each pair of processors, a voter and an improper sequence detector component disables the output module, if a majority of signals vote that output module fails. In addition, the system uses 2-of-3 voting, the system remains operational in the presence of up two transient or hard failures.

摘要： A dual/triple redundant computer system having in one of the preferred embodiments triple redundant I/O modules and dual redundant central processor modules (CPM) that operate in parallel executing the same application program. Each input module includes three input circuits operating in parallel. The first CPM receives input data from first and third input circuits and transmits input data of the first input circuit to the second CPM. The second CPM receives input data from second and third input circuits and transmits input data of the second input circuit to the first CPM. Each CPM then performs a two-out-of-two vote among input data produced by first, second, and third input circuits and utilizes an outvoted data as input to the application program to provide output data by execution of the application program.Each output module includes three microcontrollers operating in parallel. First and second microcontroller receives output data respectively from first and second CPM, while a third microcontroller receives at the same time output data from both first and second CPM. First microcontroller transmits output data to a first and a second output circuit. Second microcontroller transmits output data to second and third output circuit. The third microcontroller performs a selected logic operation among output data produced by first and second CPM and then transmits a result of this operation to third and first output circuits. Each output circuit generates a logical product of output data received from two associated microcontrollers. Outputs of first, second, and third output circuit are connected to each other for providing a two-out-of-three voting among output data produced by first, second, and third microcontroller, and for allowing the system to generate a system output as a result of a two-out-of-two voting of output data generated by first and second central processor modules.

摘要： A system and method for fast, automatic balancing of an AC bridge utilizes a two-stage process. During the first stage, the phase of the bridge voltage is matched, while during the second stage, the amplitude is minimized. The voltage matching process is based on halving the range of measured voltage amplitudes at each step, using two samples to identify the next half-range, resulting in an n-step recursive algorithm with “n” defining the resolution of the process. As such, the phase-matching process requires only three samples per step, and only four steps for 1° resolution. Consequently, the computational power needed to carry out the two-stage process is minimal, requiring only comparison of the three sampled voltages, thereby resulting in a balancing process that is performed fast and efficiently.

摘要翻译：一种用于快速，自动平衡交流电桥的系统和方法采用两阶段过程。在第一阶段期间，桥电压的相位匹配，而在第二阶段期间，振幅被最小化。电压匹配过程基于在每个步骤中将测量的电压幅度的范围减半，使用两个样本来识别下一个半范围，导致n阶递归算法具有定义该过程的分辨率的“n”。因此，相位匹配过程每步骤仅需要三个样本，只有四个步骤，分辨率为1°。因此，执行两级处理所需的计算能力是最小的，仅需要对三个采样电压进行比较，从而导致快速且有效地执行的平衡处理。
