The present application provides a noise source analysis method including measuring a noise using voltage sensorsandwhich are time-synchronized with each other and making an analysis to identify a noise source which is a cause of noise based on data of the noise measured by the voltage sensorsand

Noise source analysis method

A method for managing an assembling process of an electrical product. The electrical product at least includes a substrate with a semiconductor component mounted thereon and a power supply circuit. In the method, during assembly of the electrical product, a potential difference between two points on electric wires or signal wires electrically connected with an impedance element, which is inside the electrical product, interposed therebetween is constantly measured. Also, in the method, if a change that exceeds a predetermined threshold value, based on which electrostatic discharge noise and a normal potential range are distinguished from each other, occurs in the potential difference between the two points, measurement data on the potential difference between the two points is recorded and a mark for indicating that the electrical product was affected by electrostatic discharge is provided to the electrical product.

Method for managing assembling process of electrical product

An automatic remote monitoring and diagnosis system includes an environmental sensor and a physical sensor which measure environmental data and physical data, respectively, on electronic control devices and send the data by wireless communication, a wireless server which collects the measurement data of the sensors, a diagnostic client connected to the wireless server by a first communication network and that collects the measurement data from the wireless server, a diagnostic server connected to the diagnostic client by a second communication network and that carries out a diagnosis based on the measurement data from the diagnostic client, a data retaining device which retains the measurement data, and a knowledge database which stores information necessary for the diagnosis. The diagnostic server sends results of the diagnosis and a remedy to the diagnostic client via the second communication network.

Automatic remote monitoring and diagnosis system

Various sensors are provided inside control equipment, and it is determined whether environment inside the control equipment is abnormal or not, based on data obtained from the sensors.
