Abstract: A remote fire detection system includes a plurality of sensor nodes, each comprising a smoke sensor, a temperature sensor, a gas sensor, and a processor having inputs coupled to the outputs of the sensors. The processor processes the sensor signals to generate at least one of smoke, temperature, or gas metric information, and determines a unique time window within a reporting period. A transmitter transmits report generated by the processor during the unique time window within the reporting period. A personnel node includes a location processor that generates location information of the personnel node and a transmitter that transmits the location information. A gateway node includes a receiver that receives reports generated by the plurality of sensor nodes during the unique time window within the reporting period.

Abstract: The present invention provides a highly sensitive, intelligent, reliable, and effective process and system for detecting fire, which may be used in any industrial or other environment. The process and system for flame detection in accordance with the present invention features wide infrared spectrum sensitivity, which facilitates increased sensitivity to any sign of a flame or fire. The process and system of the present invention utilizes digital processing and analysis of data, calibration of operation parameters from temperture data, an intelligent controller (microprocessor) for discriminating against false alarms, and an elaborate multi-stage alarm system, selectively triggered by the controller.

Abstract: The present invention relates to a flame detector and protective cover with wide spectrum characteristics. The novel flame detector has wide spectrum sensitivity, which facilitates increased sensitivity to any sign of a flame or fire. The protective cover has wide spectrum transmittance characteristics. The protective cover facilitates reduced cleaning requirements and less disruption of the automated process for cleaning purposes. The wide spectrum transmittance characteristics of the protective cover enable it to be used with any flame detector utilizing non-ultraviolet sensing techniques.
Abstract: A system and method for coincidence detection of ungrounded or inadequately grounded parts during the electrostatic coating process in order to improve production flow, provide an overall cost saving by efficient use of the coating material and prevention of accidental fires and false shutdown during production. The present invention utilizes a coincidence detection technique which performs a test for radio-frequency electromagnetic energy radiated by sparking and/or corona discharge caused by ungrounded parts outside a electrostatic coating area and a test for sensing and discriminating spurious radio-frequency electromagnetic energy radiated by sparking and/or corona discharge caused by any other external source. In accordance with one specific embodiment, the test performed outside the booth may include a further test for detecting ultraviolet energy radiated by the sparking and/or corona discharge.
