  • Patent number: 12270900
    Abstract: An acoustic analysis system includes an acoustic sensor array that receives acoustic signals from a target scene and outputs acoustic data based on the received acoustic signals. A processor receives a plurality of acoustic data sets from the acoustic sensor array, representative of the target scene at different points in time. The processor determines one or more locations within the target scene represented by the plurality of acoustic data sets, each being a location of an acoustic signal emitted from the target scene. For each acoustic signal, the processor classifies the acoustic signal as an intermittent acoustic signal or a continuous acoustic signal, generates accumulated-time acoustic image data based on the plurality of acoustic data sets, and generates an accumulated-time display image for presentation on a display.

  • Patent number: 12247889
    Abstract: A temperature sensor includes a platinum member having a base portion and a plurality of prongs extending from the base portion. The platinum member is positioned within a housing that includes a first platform having a first support surface supporting the base portion, and a second platform having a second support surface spaced apart from the first support surface. The second support surface supports an end portion of at least one prong of the plurality of prongs, and medial portions of the plurality of prongs between the first and second support surfaces are suspended at a distance from an interior surface of the housing. In some cases, the housing further includes one or more support members between the first and second platforms that project from the interior surface of the housing toward the medial portion of one or more prongs to limit an amount of bending of the prongs.

  • Patent number: 12249179
    Abstract: A system for screening persons' temperatures comprises an imaging device configured to generate imagery data, including infrared image data, of a first scene and a second scene. The system receives imagery data from the first scene, identifies persons in the scene using the imagery data, and determines each person's temperature. The system further compares the persons' temperatures to a threshold and indicates a person should be directed to the second scene if the person's temperature is above a threshold. Subsequently, the system determines and compares the person's temperature in the second scene and provides an indication if the person's temperature exceeds a second threshold. Further, a confidence factor can be associated with determinations of persons' temperatures.

  • Patent number: 12117523
    Abstract: An acoustic analysis system includes an acoustic sensor array that receives acoustic signals from a target scene and outputs acoustic data based on the one or more acoustic signals. A processor receives a first set of acoustic data representing a first portion of the target scene and having a first field of view (FOV), generates a first acoustic image based on the first set of acoustic data, receives a second set of acoustic data representing a second portion of the target scene and having a second FOV, wherein the second FOV is different than the first FOV, generates a second acoustic image based on the second set of acoustic data, registers the first acoustic image and the second acoustic image to form an aligned first acoustic image and second acoustic image, and generate a panorama comprising the aligned first acoustic image and second acoustic image for presentation on a display.

  • Patent number: 12107751
    Abstract: Apparatus and methods for testing network cabling includes processing circuitry that receives an indication of a user-selected network test of a plurality of network tests. The respective network tests have respective sets of test requirements with different levels of rigor. The test circuitry conducts a wire map test to identify which network tests can be conducted. Thereafter, a common set of test results is produced based on measurement of a common set of parameters pertinent to the network tests that can be conducted. The processing circuitry evaluates the common set of test results with respect to the respective sets of test requirements to determine one or more passing network tests. A plurality of test reports corresponding to the plurality of network tests is graphically displayed along a curve having a common center, wherein each test report indicates whether the corresponding network test is a passing network test.

  • Patent number: 12085217
    Abstract: A holder secured to a vertical column by a cross support holds an object in a fixed position. The holder includes a tube that can be secured to the cross support. A movable clip at a first end of the tube is configured to hold the object, e.g., a probe held in a calibration bath. The movable clip includes an aperture. When the movable clip is in an extended position, an object can be inserted into the aperture. When the movable clip moves toward a retracted position, the object is held within the aperture. A cap at the second end of the tube is coupled to the movable clip by a spring inside the tube. The movable clip exerts an adjustable holding force on the object by adjusting a number of turns of the spring between the cap and the movable clip. A central holding device may support multiple holders.

  • Patent number: 12085468
    Abstract: Methods and systems include a universal, device-agnostic calibration process in which measured indications output by a device under test (DUT) (or corrected or converted indications derived therefrom) may be compared with calibration thresholds for any type of DUT to be calibrated. A complete, universal, and extensible calibration process is thus achieved that is capable of accommodating routine and complex calibration scenarios alike. A common set of statistics may be generated for all devices to be calibrated, without regard to the particular device under test, and statistics of the common set of statistics may be evaluated to determine the calibration state of the DUT. Additionally, the methods and systems disclosed herein provide for generating a comprehensive set of measurement records that may include some or all original observations, calculations, corrections, conversions, environmental factors, and measurement results, e.g.

  • Patent number: 12088910
    Abstract: Systems for guiding a user through a workflow routine can include an inspection tool, a user interface, memory, and a processor. The processor can provide instructions via the user interface to perform a workflow routine using the inspection tool and save acquiring inspection data to memory. Instructions can direct a user to which equipment to inspect and/or how to collect inspection data associated with one or more pieces of equipment. Systems can determine which equipment is available for inspection by the user, such as via image recognition or proximity detection, and instruct a user to acquire inspection data associated with such equipment. Workflow routine instructions can be provided to the user via various devices, such as an inspection tool, smartphone, or a tablet.

  • Patent number: 12061213
    Abstract: A sensor probe includes a body having first and second channels that are spaced apart and extend through the body approximately parallel to each other. A first end of a Rogowski coil is fixed within the first channel. The Rogowski coil passes through the second channel and loops back to the first channel where a second end of the Rogowski coil is selectively insertable into the first channel opposite the first end of the Rogowski coil. A non-contact sensor coupled to the body is positioned between the first and second channels to measure a parameter of an insulated conductor situated within the loop formed by the Rogowski coil. The size of an interior region within the loop is selectively adjustable by sliding movement of the Rogowski coil within the second channel.

  • Patent number: 12013305
    Abstract: A fiber optic test device is provided that includes a light source pigtailed with a first end of a non-bend insensitive multimode fiber (non-BIMMF). A second end of the non-BIMMF is fusion spliced to a first end of a reference grade bend insensitive multimode fiber (BIMMF). A reference grade optical fiber connector is attached to a second end of the BIMMF, which is coupled to a first end of a reference grade bulkhead adapter. The non-BIMMF is deformed so that a specific launch condition, such as encircled flux, is achieved at the first end of the BIMMF. A test reference cord, which contains a reference grade BIMMF having similar geometric properties as the BIMMF that is fusion spliced to the non-BIMMF, is attached to a second end of the bulkhead adapter. Modal transparency is achieved and the launch condition is maintained at the output of the test reference cord.
