| 20130214164 | METHOD AND APPARATUS FOR DETECTING SPECTRAL CHARACTERISTICS OF MULTI-BAND MOVING OBJECTS - A method for detecting spectral characteristics of multi-band moving objects. The method includes: 1) dividing a full field of view into several subfields of view, and scanning and extracting suspected objects in each subfield one by one; 2) correlating interrelated suspected objects in adjacent subfields via coordinates to determine objects of interest that exist in the full field of view; 3) calculating the speeds of the objects of interest; 4) calculating average speed of all of the objects of interest and classifying the objects of interest according to their average speed; 5) compensating and rectifying the objective spectrum obtained from calculation; and 6) matching the compensated and rectified objective spectrum with a spectrum fingerprint database whereby realizing recognition of the multi-band moving objects. | 08-22-2013 |
| 20160054245 | THERMOGRAPHY-BASED METHOD FOR DETECTING DEFECTS IN SEALS WITH CONDUCTIVE INNER-SEALS - The present disclosure provides a method for detecting thermal sealing defects of a container during its transportation along a process line. The method is particularly suitable for containers caped with a cap liner and sealed with an inner seal. The method makes use of a high frequency heat (e.g. by a high frequency heat induction unit) to cause eddy current in the inner seal after which there is sensing by an IR imager of radiation emitted from the conductive innerseal to generate sensed IR image data indicative of the sensed radiation. The sensing is characterized by at least one of (i) a time window of a sensing session of between 50 msec to 300 msec during which said container is being transported through the FOV; and (ii) a sensing range of a wavelength spectrum region from 2 μm to 6 μm. The IR data is then processed so as to generate output data indicative of the presence or absence of at least one defect in the sealing of the container by said innerseal. | 02-25-2016 |

| 20080230701 | METHOD FOR DETECTING A FIRE CONDITION IN A MONITORED REGION - A method of detecting a fire condition in a monitored region including the operations of: concurrently monitoring the region using: a plurality of fire combustion product emission band sensors, each band sensor sensitive to radiation within a respective waveband which includes at least part of a respective fire combustion product emission band of a plurality of fire combustion products, the plurality of fire combustion products equal to n; a first reference band sensor sensitive to radiation within a first reference waveband which includes at least some wavelengths shorter than the n fire combustion product emission bands; and a second reference band sensor sensitive to radiation within a second reference waveband which includes at least some wavelengths longer than the n fire combustion product emission bands; and using the band sensors to obtain n+2 measurement values of radiation intensity emitted from the monitored region in determining the presence or absence of the fire condition. | 09-25-2008 |
| 20090127464 | Flame detector and a method - A flame detector is provided which comprises a housing ( | 05-21-2009 |
| 20100288929 | Device and method for detecting flames - A device for detecting flames in which at least two identical detectors are disposed next to one another. Each detector has an identical signal processing circuit having an amplifier and an A/D converter, and a symmetrical and similar layout, i.e., conductor track placement. Each of the detectors covers a different wavelength range, by way of a preceding filter, and the signal detection takes place at the same time and synchronously, so that a precise analysis of the received radiation occurs using simple algorithms, independent of disruptive influence variables. By using the same detectors and the same signal processing systems, as well as the symmetrical and similar configuration of the conductor track placement, as well as the synchronous control of the signal recording, interference variables occur uniformly on all optical reception channels. This uniform interference can be compensated without complicated algorithms. | 11-18-2010 |
