Publication number: 20170363475Abstract: A flame detector configured for radiant energy monitoring, quantification, and information transmission. The system has at least one optical sensor channel, each including an optical sensor configured to receive optical energy from a surveilled scene within a field of view, the channel producing a signal providing a quantitative indication of the optical radiation energy received by the optical sensor within a sensor spectral bandwidth. A processor is responsive to the signal from the at least one optical sensor channel to provide a flame present indication of the presence of a flame, and a quantitative indication representing a magnitude of the optical radiation energy from the surveilled scene. An Artificial Neural Network may be used to provide an output corresponding to a flame condition.Type: ApplicationFiled: August 31, 2017Publication date: December 21, 2017Inventors: Shankar B. Baliga, Javid Huseynov, John G. Romero, Cristian Filimon

Patent number: 9482592Abstract: An embodiment of a directional ultrasonic gas leak detector includes an array of spaced MEMS microphones, each responsive to incident airborne ultrasonic energy from gas leak sources to generate a microphone signal. A beamforming processor is responsive to the microphone signals from the array to generate processor output signals indicative of estimated angles of arrival of ultrasonic energy incident on the array. The array may be disposed in an explosion proof housing structure for operation in hazardous location, or implemented as an intrinsically safe device. In another embodiment, a display is responsive to the processor output signals to generate an image representative of a surveilled scene with the estimated magnitudes of incident energy at beam directions overlaid onto the image.Type: GrantFiled: September 24, 2014Date of Patent: November 1, 2016Assignee: General Monitors, Inc.Inventors: Javid J.

Publication number: 20150204725Abstract: A flame detector for industrial safety applications in hazardous locations, configured for radiant energy monitoring, quantification, and information transmission. The system has at least one optical sensor channel, each including an optical sensor configured to receive optical energy from a surveilled scene within a field of view at a hazardous location, the channel producing a signal providing a quantitative indication of the optical radiation energy received by the optical sensor within a sensor spectral bandwidth. A processor is responsive to the signal from the at least one optical sensor channel to provide a flame present indication of the presence of a flame, and a quantitative indication representing a magnitude of the optical radiation energy from the surveilled scene. An Artificial Neural Network may optionally be used to provide an output corresponding to a flame condition.Type: ApplicationFiled: January 23, 2014Publication date: July 23, 2015Inventors: Javid Huseynov, Shankar B.

Patent number: 8955383Abstract: An ultrasonic gas leak detector is configured to discriminate the ultrasound generated by a pressurized gas leak into the atmosphere from false alarm ultrasound. An exemplary embodiment includes a sensor for detecting ultrasonic energy and providing sensor signals, and an electronic controller responsive to the sensor signals. In one exemplary embodiment, the electronic controller is configured to provide a threshold comparator function to compare a sensor signal value representative of sensed ultrasonic energy to a gas detection threshold value, and an Artificial Neural Network (ANN) function for processing signals derived from the digital sensor signals and applying ANN coefficients configured to discriminate false alarm sources from gas leaks. An output function generates detector outputs in dependence on the threshold comparator output and the ANN output.Type: GrantFiled: June 27, 2012Date of Patent: February 17, 2015Assignee: General Monitors, Inc.Inventors: Javid J.

Patent number: 8797830Abstract: An explosion-proof system for generating acoustic energy. An exemplary embodiment of the system includes a main housing defining an open housing space and an opening. A cover structure is configured for removable attachment to the main housing structure to cover the opening and provide an explosion-proof housing structure. The cover structure includes an integral head mass. An acoustic energy emitting assembly includes the head mass, and an excitation assembly disposed within the explosion-proof housing structure. An electronic circuit is disposed within the explosion-proof housing structure to generate a drive signal for driving the excitation assembly to cause the acoustic energy emitting assembly to resonate and generate acoustic energy. In one embodiment the acoustic energy is a beam of ultrasonic energy useful for testing ultrasonic gas detectors. A method is also described for testing ultrasonic gas leak detectors using an ultrasonic source.Type: GrantFiled: February 2, 2011Date of Patent: August 5, 2014Assignee: General Monitors, Inc.Inventors: Shankar B.
