A multi-zone monitoring system is disclosed. The system includes a plurality of sensor modules configured to monitor conditions in a plurality of detection zones. The sensor modules include a combination of detection devices configured to detect different conditions based on a designated zone of each sensor module. The system further includes a reporting device in communication with each of the sensor modules. The reporting device is configured to report the status of each of the detection zones based on indications communicated via the detection devices in the corresponding detection zone.

Systems and methods for monitoring and controlling burning operations are provided. A method of one embodiment includes igniting oil or gas with a burner (282) during a burning operation and monitoring the burning operation with a camera (290). This monitoring of the burning operation can include acquiring image data for a flame (290) of the burner via the camera and analyzing the acquired image data to detect image features indicative of combustion of the oil or gas via the burner. Additional systems, methods, and devices are also disclosed.

A flame detection system includes a determiner and an outputter. The determiner is configured to, when image processing performed on image data detects ultraviolet light, determine that a light emitting source is a fire flame. The outputter is configured to output a determination result by the determiner.

A computer system determines a likelihood of the presence of flame in a scene. The system obtains a series of digital infrared and optical images of the scene; identifies a candidate region in a location of the scene based on analysis of the infrared images;

identifies an optical image slice based on analysis of the optical images and the location of the candidate region; and determines a likelihood of the presence of flame in the scene based on analysis of the optical image slice. Analysis of the infrared images includes detecting a high-temperature image region that exceeds a threshold temperature; detecting a turbulent motion image region; and determining whether the turbulent motion region is within a specified proximity of or overlaps with the high-temperature region. The optical image slice may be provided to a trained neural network, which returns a degree-of-confidence value that indicates whether flame is present.

A sensor system for use in a gas turbine engine. The sensor system includes a reflective surface configured to reflect optical features corresponding to combustion in a combustion chamber that exit the combustion chamber via at least one opening therein. The sensor system further includes an optical sensor configured to receive the reflected optical features from the reflective surface.

A temperature sensing system for a resistive welding process for a tube performs repeatable temperature measurement using a camera to detect multiple distinct visible light wavelengths even as the ambient environment in the view path changes. Sensed colors in a field of view in the vicinity of a weld are output to a computing element that calculates a corresponding temperature and alerts an operator when the sensed color exceeds a preset color range.

The present invention relates to an intelligent flame detection apparatus and method using an infrared thermogram, which combine a conventional flame detector with an infrared thermographic camera and an infrared thermogram processing technology, and which enable whether a flame signal received from a flame sensor is an allowed flame or an artificial flame to be accurately detected, thereby improving the accuracy of fire alarms.

A semaphore for guiding an occupant to safety during an emergency event communicates with a gunfire detector to provide a visual cue conveying whether it is safe to proceed through an entryway in an active shooter event.

The present invention relates to an apparatus for metrological detection of a fire-like phenomenon (1), in particular a spark, flame or embers or hot particle phenomenon in a reservoir (2) through which media flows or which is loaded with media, comprising a measurement arrangement (4) configured to record measurement data, the measurement arrangement (4) comprising a first and a second measuring unit (11, 12) for the detection of electromagnetic radiation (5) emitted by the fire-like phenomenon (1) in a first or second wavelength range, respectively, optionally comprising a third measuring unit (13) for detecting ambient light (7) as well as optionally comprising a sensor unit (14) for the measurement of media-specific or environment-specific measurement data.

In order to reduce the risk of false alarms with such an apparatus and to improve the detection and risk assessment of fire-like phenomena, it is proposed to provide a checking means (8) that is adapted to check at a current time point (t.sub.A) on the basis of measurement data recorded by the measurement arrangement (4) and/or stored medium- or environment-specific characteristic data, whether an adjustment criterion (A) is satisfied, wherein if the adjustment criterion (A) is satisfied, a measurement sensitivity (M.sub.1, M.sub.2, M.sub.3) or an operating parameter (P.sub.1, P.sub.2, P.sub.3) of at least one of the measuring units (11, 12, 13) can be adjusted adequately for the situation using a control means (10).

Furthermore, a method for the metrological detection of fire-like phenomena (1) and a system for needs-based and reliable elimination of a hazardous state produced by a fire-like phenomenon is proposed with the invention.

A flame detector includes a beam splitter to split mid-wave infrared radiation (MWIR) and long-wave infrared radiation (LWIR) into an MWIR component and an LWIR component. An MWIR detector detects the MWIR component and an LWIR detector detects the LWIR component. The flame detector analyzes the MWIR component to determine the presence of a flame and analyzes the LAIR component to determine whether the system is functioning properly.
