Fault detection and diagnosis is a key component of many operations management automation systems. A "fault" is another word for a problem. A "root cause" fault is a fundamental, underlying problem that may lead to other problems and observable symptoms. (It might not be directly observable).

  • Metal Detector Circuit Diagram and Working

    5 mins readJul 31, 2017When the metal is detected the LC circuit will have changed signal. The changed signal is given to the proximity detector (TDA 0161), which will detect the change in the signal and react accordingly. The output of the proximity sensor will be of 1mA when there is no metal detected and it will be around 10mA when coil is near to the metal

  • Detecting Microelectronic Defects | SIGNAL Magazine

    Jul 01, 2019Conventional methods for defect detection usually involve electron microscopy or atomic force microscopy. “The main disadvantage for those methods is that they’re slow,” he says. “They are serial scanning processes. And being able to inspect an 18-inch wafer would just take way too long.”

    1. Direct Connection. In the first two methods, direct connection and direct induction, the transmitter discharges a radio signal onto the target line (with a frequency of 8 KHz, 33 KHz, 65 KHz, etc.), and the line can then be located and traced out using a hand-held receiver set to the same frequency. The Direct Connection method is performed by plugging a direct connection lead into the transmitter output
