  • Patent number: 11474046
    Abstract: Corrosion detection systems and methods can include at least one fiber optic cable embedded in a material having at least two layers. Two of the layers can define an interface, and the fiber optic cable can be embedded at the interface. Each fiber optic cable can have a plurality of Fiber Bragg Gratings (FBG's) formed therein at predetermined intervals. Each FBG can have a preselected geometry that can only allow a predetermined light wavelength to pass therethrough. A light source for inputting light and a photodetector can be connected to opposite exposed ends of the fiber optic cable. As corrosion occurs near an FBG, it experiences mechanical strain, which can further cause a slightly different wavelength to pass through the fiber optic cable. The change in in wavelength can be detected by the photodiode as being indicate of corrosion occurring at the site near the FBG.

  • Patent number: 11448505
    Abstract: A piezoelectric body of a sensor includes a driving arm and detecting arm which extend from a base part in a y-axis direction. Excitation electrodes vibrate the driving arm in an x-axis direction. Detecting electrodes enable detection of a signal due to deformation in a z-axis direction of the detecting arm. The piezoelectric body has anisotropy causing vibration of torsional deformation when the driving arm vibrates in the x-axis direction. When the driving arm bends to a +x side, the base part flexes so that a connection position in the base part is displaced to one side in the z-axis direction. The cross-section of the driving arm perpendicular to the y-axis direction causes a bending stiffness to the +x side and to the other side in the z-axis direction is smaller than a bending stiffness to the +x side and to the one side in the z-axis direction.

  • Patent number: 11204278
    Abstract: A system is provided in an automated machine vision inspection environment. The system includes inspection cameras and a spectrophotometer or spectrometer, both implemented to be used online to detect the absolute colors of printed portions of items being inspected. The spectrophotometer or spectrometer is aimed at a fixed spot within a field of view of one of the digital cameras of an inspection system, which has a-priori knowledge as to exactly where the spectrophotometer or spectrometer is aimed. The image taken by the camera will be used to determine whether the desired measurement spot on the decoration pattern has actually been measured by the most recent snap of the spectrophotometric data. When the vision system determines that the spectrophotometer or spectrometer was truly aiming at the correct region when it captured its inspection data, it will instruct the system to accept the color measurement and will log the related data and information accordingly.

  • Patent number: 11169050
    Abstract: Apparatus for detecting high speed hits on a target is disclosed. A first set of detection lines are would in one direction around a target, and a second set of detection lines is wound orthogonal or diagonal to the first set of lines around a target. Where the detection lines are light-transmissive fibers, cutting of a fiber by a high-speed projectile or fragment causes a flash of photons that are detected by a detector attached to that line. Materials the lines are embedded in may also cause bursts of photons when pierced that is detected by detectors. The lines may be laid in prefabricated panels, or attached to an exterior or interior skin of a target. Moldings may be used to ensure that a bend radius of the light-transmissive fibers is not exceeded.

  • Patent number: 11143865
    Abstract: This disclosure describes a novel lens system having an entrance pupil at a location matching, or nearly matching, the eye's optical system entrance pupil. The described lens system is significantly thinner than a single-aperture lens with matched entrance pupil and is achieved by using an array of camera elements. Each camera element contains camera optics called “lenslets” and a sensor (e.g., an image or depth sensor), where a lenslet can include one or more lens elements (e.g., a compound lens). Individual camera elements can be arranged such that THEIR optical axes intersect at, or near, the eye's entrance pupil location. In addition, each camera element's field-of-view (FOV) corresponds to a small sector of a large FOV. The FOVs of adjacent camera elements can be non- or slightly-overlapping so that a wide-angle image can be formed by concatenation of the individual camera element images.

  • Patent number: 11143585
    Abstract: A photoelectrical device for detection of bacterial cell density includes a substrate, a driving electrode layer, an AC power source and a photoelectric conversion layer. The driving electrode layer is disposed on the substrate and includes a central electrode and a peripheral electrode pattern surrounding the central electrode. A fluid sample is disposed on the driving electrode layer. The AC power source is electrically connected to the driving electrode layer, and used to produce a non-uniform alternating electric field in the fluid sample on the driving electrode layer for driving the target bioparticles to gather up on the central electrode to form a particle cluster. The photoelectric conversion layer is used for receiving a light detecting beam after passing through the particle cluster and outputting an electric current based on the optical density of light detecting beam. The electric current changes as a concentration of the target bioparticles changes.

  • Patent number: 11137519
    Abstract: Apparatus and associated methods relate to sampling a large volume of a cloud atmosphere so as to obtain a large signal response from even a sparse distribution of water droplets in the cloud atmosphere. Such a volume can be probed by projecting an uncollimated optical beam into the cloud atmosphere and sampling the signal backscattered from the water droplets located within the probed volume. The uncollimated optical beam can be generated by projecting a diverging pulse of light energy from a polished end of a first optical fiber. A second optical fiber can be used to receive the optical signal backscattered from the cloud atmosphere. The second optical fiber can also have substantially the same field of view as the first optical fiber, so as to receive signals from a volume of the cloud atmosphere that is substantially commensurate with the probed volume.
