  • Patent number: 10375325
    Abstract: Systems and methods can be used to detect thermal anomalies in a target scene of an infrared image. Acquired thermal image data can be compared to a statistical thermal profile to detect thermal anomalies in the image data. Anomaly data based on the comparison can be used to generate an image representing locations and/or severity of detected anomalies. Systems can be used to acquire thermal image data for generating and/or updating statistical thermal profiles for use in anomaly detection processes. Auxiliary measurement devices can provide measurement data representative of one or more parameters of the target scene. The measurement data can be used to select from a plurality of possible statistical thermal profiles associated with the target scene to best match the current parameters of the scene.

  • Patent number: 10366496
    Abstract: The invention relates generally to edge detection and presentation in thermal images. Infrared and visible light images comprising at least partially overlapping target scenes are analyzed. An edge detection process is performed on the visible light image to determine which pixels represent edges in the target scene. A display image is generated in which some pixels include infrared image data and in which pixels corresponding to edges in the visible light image include a predetermined color and do not include corresponding infrared image data to emphasize edges. Edge pixels in the display image can include exclusively the predetermined color, or in some examples, a blend of a predetermined color and visible light image data. Methods can include replacing one or the other of visible light edge pixels or corresponding infrared pixels with the predetermined color before combining the visible light and infrared image data to create a display image.

  • Patent number: 10367713
    Abstract: A system and method for receiving a data packet in a cable network testing device from a remotely located cloud host service/device. The data packet contains selected cable test device configuration instructions. The selected device instructions, once implemented in a cable test device, configure the cable test device to perform one or more cable network testing procedures in accordance with predetermined testing parameters. The cloud host service/device contains a plurality of test device configuration instructions to be selected by a user, which user may be remote from the cable test device.

  • Patent number: 10359517
    Abstract: An apparatus includes a reflector, a microphone coupled to the reflector, laser emitters coupled to the reflector, and a laser range finder coupled to the reflector. The laser range finder is configured to output a signal indicative of a distance between the reflector and an object. The apparatus adjusts a position and/or a power level of the laser emitters based on the distance between the reflector and the object. Additionally or alternatively, the apparatus adjusts a position and/or a power level of the laser emitters based on a type of sound waves. Laser beams of light emitted by the laser emitters visually indicate a region in which a source of detected sound waves is located.

  • Patent number: 10359494
    Abstract: Systems and methods provide a portable, verified voltage source that allows safe testing of separate non-contact voltage measurement systems. A proving unit of the present disclosure provides a known or specified alternating current (AC) voltage output across an insulated wire, which AC voltage may be fixed or may be user-selectable through a suitable user interface. The proving unit may include a visual indicator and/or an audible indicator that provides the user with an indication confirming that the proving unit is supplying an output voltage with the specifications of the proving unit, so the user will know that the proving unit is operating normally and is ready for testing a non-contact voltage measurement system. If the proving unit cannot provide the specified voltage output, the indicator(s) provides a signal to the user that the proving unit is currently non-functional.

  • Patent number: 10355951
    Abstract: A test instrument provides suggested next operational step function to provide a user with assistance during testing. A display is provided to show the amount of a project that has been completed, for example as a percentage completed value. Individual test results may be saved to a ‘fix later’ list, which may be later accessed to re-test items that may not have passed on initial testing.

  • Patent number: 10352967
    Abstract: Systems and methods provide measurement of alternating current (AC) electrical parameters in an insulated wire without requiring a galvanic connection between the insulated wire and a test probe. Measurement systems or instruments may include a housing that includes both a non-contact voltage sensor and a non-contact current sensor. The measurement system obtains measurements from the voltage sensor and the current sensor during a measurement time interval and processes the measurements to determine AC electrical parameters of the insulated wire. The AC electrical parameters may be presented to an operator via a visual indicator device (e.g., display, lights). The AC electrical parameters may additionally or alternatively be communicated to an external device via a wired and/or wireless communications interface.

  • Patent number: 10337962
    Abstract: A smart phone user captures video and still images of a motor and makes a sound recording of his observations. The images and recordings are tagged with a date/time stamp, a serial number, bar code, matrix code, RFID code, or geolocation and sent wirelessly to an infrared camera. The infrared camera has a collocation application that reads the tag and creates a folder which holds the infrared image and the auxiliary information from the smartphone related to an asset. The collocation program also adds icons to the infrared image. By operating the user interface (not shown) of the infrared camera, the user may select an icon to view the images and listen to the sound recording.
