Suitability of an operational state of a steam-using equipment is accurately estimated to allow for early detection of a sign of abnormality in the steam-using equipment. A steam-using facility monitoring system composed of a steam-using equipment includes a control state detector that detects a state of a steam controller provided in a steam pipe accompanying the steam-using equipment, and an operational state estimating means having a signal input unit that inputs a detection signal from the control state detector and an operational state estimation unit that estimates the operational state of the steam-using equipment based on one inputted detection signal or a preset particular combination of detection signals.

A manufacturing equipment diagnosis support system includes: a data collector which collects and records respective data in plural apparatuses to be monitored provided in manufacturing equipment; a data analysis device; and a display. The data analysis device includes: a data analysis range setting unit which sets an analysis range of data, by an item of data and time period; a data grouping unit which classifies the data into a category based on specification and use condition of the apparatus to be monitored, and a category based on a physical quantity which the data shows, to group the data; a feature extracting unit which extracts a feature in each of the data items; an unusual phenomenon specifying unit which specifies an unusual phenomenon candidate item; and a testing unit which tests whether there is a significant difference or not between the unusual phenomenon candidate item and an other data item.

Methods and systems for monitoring a brush holder assembly and/or detecting wear of a brush in a brush holder assembly are disclosed. One method includes sending data from a plurality of remote monitoring locations to a central control unit, where the data may be evaluated in order to monitor states of brushes at a plurality of remote electrical facilities. For example, multiple images of a marker tracking longitudinal movement of the brush may be acquired. A comparison of the images, for example, a comparative imaging technique, such as pixel-by-pixel comparison, may then be performed in order to evaluate a condition of the brush, such as the wear rate, wear state, or life expectancy of the brush.

Provided are a system and a method for diagnosing a state of mechanical equipment. More particularly, provided are a system and a method for diagnosing a state of mechanical equipment, wherein a health index is calculated for various levels in the equipment using one or more sensor parameter values related to individual components of the equipment, and then a current state value of the equipment is finally derived.

A system includes a processor and a memory system in communication with the processor. The memory system stores instructions that when executed by the processor result in the system being operable to identify a system hazard boundary of a monitored system and a system nuisance boundary of the monitored system. The system is also operable to determine a must-trip condition based on the system hazard boundary and a must-not-trip condition based on the system nuisance boundary. The system is further operable to output a protection margin for the monitored system based on the system hazard boundary and a difference between the must-trip condition and the must-not-trip condition.

A testing device is disclosed for testing a connection interface coupled onto an assembly line between first and second vehicle components. The testing device includes a tool configured to couple the connection interface, at least one test adapter for testing the coupling of the connection interface, and a sensor device for acquiring a force progression which acts during and/or after the coupling in the connection interface, The testing device also includes an evaluation device to evaluate the force progression.

An abnormality in a device of interest is detected on the basis of the distance from a predetermined reference curve to a point represented by a first index value and a second index value in a two-dimensional plane having the first index and the second index as axes.

Systems, methods, and devices for fault detection and tolerance in a downhole tool string are provided. If a fault is detected in an electrical path between tools of downhole tool string, one or more switches of a fault detection and tolerance circuit may be kept open to isolate the fault in an electrical path between tools of downhole tool string. If a fault is not detected, one or more switches of a fault detection and tolerance circuit may be closed to enable the transmission of signals on the electrical path. In some embodiments of fault detection and tolerance circuits, an additional one or more switches may be kept open to isolate the fault in electronics of the tool.

A system for managing a vehicle battery that is chargeable/dischargeable and stores energy for driving a vehicle driving motor is disclosed. The system for managing a vehicle battery as disclosed includes a controller that measures a voltage of each of a plurality of battery cells in a vehicle battery when a voltage applied to the vehicle battery is constant, and determines whether the plurality of battery cells is abnormal based on a deviation between the measured voltages of the plurality of battery cells.

An arc detection and intervention system for a solar energy system. One or more arc detectors are strategically located among strings of solar panels. In conjunction with local management units (LMUs), arcs can be isolated and affected panels disconnected from the solar energy system.
