    Abstract: The present disclosure is directed to methods and systems for inspecting insulated equipment for any corrosion under insulation (CUI). The system includes a device comprising transmitter and receiver horn antennas, a vector network analyzer operatively connected to the antennas, and an infrared detector. In the method, a location for inspection of the equipment is identified. A metal jacket surrounding the location is removed without stripping the insulation. Microwaves are transmitted by the transmitted horn antenna at the location, and provide heating at the location. The microwaves are received by the receiver horn antenna after reflection off the equipment. The vector network analyzer analyzes the microwaves. The infrared detector detects infrared waves emitted from the location and develops an infrared image of the inner surface of the equipment. Based on the analysis of the microwaves and the developed image, a programmed processor determines whether CUI exists at the location.

  • Patent number: 10169671
    Abstract: An electronic device incorporates features that are dependent on finding a face by image processing of an image taken by an image capturing device. To avoid false positives and false negatives due to poor focus, exposure, or spoofing with a picture, the electronic device validates, by distance and/or temperature, a candidate face within a captured image. Distance information is used to scale the candidate face to an actual size for comparison against biometric data on a range of sizes of a human face. Detected temperature is compared against biometric data on the temperature of a human face sensed in the infrared spectrum. Confidence value for face detection is increased or decreased in relation to the validation by size/temperature. For a validated candidate having a confidence value above a threshold, the electronic device can adjust camera controls of an image capturing device or enable a face recognition security component.

    Abstract: A process for detecting oil or lubricant contamination in a manufactured product (C), preferably a cigarette (C), the process comprising adding a fluorescent taggant to oils or lubricants contained in processing machinery for said product (C), conveying (131) said product (C) past an infrared detection apparatus (140), irradiating said product (C) with infrared radiation from said detection apparatus (140) as it passes the detection apparatus (140), and detecting infrared radiation emitted from said irradiated product (C). The taggant can be in the form of a composition containing a Stokes-shifting taggant, which absorbs radiation at a first wavelength and emits radiation at a second wavelength, different from said first wavelength, dissolved or dispersed in an oil or lubricant.

  • Publication number: 20150021480
    Abstract: An imaging spectrometer, covering the visible through infrared wavelengths, which disperses the light by a plane diffraction grating behind a wedged optical element. This design uses an achromatic doublet lens with a reflective coating on its convex back surface to produce the spectra on a flat detector. Spatial keystone distortion and spectral smile are controlled to less than one tenth of a pixel over the full wavelength range, facilitating the use of simple retrieval algorithms.

  • Patent number: 8901499
    Abstract: In an embodiment, an apparatus includes a module assembly and a main assembly. The module assembly includes a module assembly housing, a first faceplate and an analysis unit attached to the first faceplate. The main assembly includes a main assembly housing, a second faceplate and an engine unit rigidly attached to the second faceplate. The engine unit generates a light that passes to the analysis unit via a first lens assembly and a second lens assembly. The first lens assembly is attached to the first faceplate and the second lens assembly is attached to the second faceplate. The module assembly when attached to the main assembly causes the first and second faceplates to act as a single mechanical unit that moves independent of movement of the module assembly housing and/or the main assembly housing.

  • Publication number: 20140008539
    Abstract: The present invention is thus directed to an automated system and method of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Such a methodology and system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.

    Abstract: A light sensor is used to detect ambient light conditions. According to an example embodiment, a light sensor (112) detects color temperature and, in some instances, intensity characteristics of ambient light (120, 130, 140) in an environment and uses these detected characteristics (116) to determine the location of the sensor relative to natural and artificial light sources. This location determination is used to selectively operate circuits in a device such as a hand-held telephone, computer device or personal data assistant (PDA).
