Abstract: Systems and methods are provided for measuring electrical parameters in a conductor without requiring a galvanic connection. A device includes a body and a clamp jaw assembly movable between an open position that allows a conductor to be moved into a measurement area, and a closed position that secures the conductor within the measurement area. The clamp jaw assembly includes sensors positioned inside a clamp jaw of the clamp jaw assembly. A user may apply a force to an actuator to move the clamp jaw assembly from the closed position into the open position so that the conductor may be positioned and secured in the measurement area. The clamp jaw assembly includes a visual indicator to guide the user to position the conductor within an optimal region in the measurement area. The clamp jaw assembly is sized and dimensioned to automatically position the conductor within the optimal region during measurements.

Abstract: Systems and methods directed toward acoustic analysis can include an acoustic sensor array comprising a plurality of acoustic sensor elements, an electromagnetic imaging tool, a distance measuring tool, and a processor in communication with the acoustic sensor array, the electromagnetic imaging tool, and the distance measuring tool. The processor can be configured to generate acoustic image data based on acoustic signals received from the acoustic sensor array and distance information received from the distance measuring tool. The processor can combine the generated acoustic image data and received electromagnetic image data from the electromagnetic imaging tool to create a display image including acoustic image data and electromagnetic image data. The processor can be configured to correct a parallax error between the electromagnetic image data and the acoustic image data based on the received distance information.

Abstract: Systems and methods provide for display of a deficiency indicator in response detection of a defined deficiency in an electric signal in an insulated wire. Measurement systems may include a housing sized and shaped to be held in a hand, a set of sensors for sensing a set of electrical characteristics of the electric signal, one or more processors, and a display provided on a surface of the housing. The measurement system may obtain measurements from the set of sensors and detect a presence of the defined deficiency based on the set of measurements. In response to detecting the presence of the defined deficiency, the measurement system may display a deficiency indicator that is representative of the defined deficiency detected.

Abstract: A camera producing visible light images with thermal data. The camera may include visible light lens and sensor, an infrared light lens and sensor, and a display. The display displays some of the visible light image and thermal data from the respective sensors. The visible light image is divided into an array of zones where each zone may provide thermal data associated with the corresponding portion of the target shown in the zone. The camera may sense infrared images also provide audible alarms where the alarm is emitted with a tone of variable output to indicate the relative level of the alarm.

Abstract: A method and apparatus for testing shield continuity are provided. In the method and apparatus, a transmitter transmits a first signal in common mode over a plurality of conductors of a cable or cabling installation having a shield. The first signal is transmitted in the common mode at a first end of the plurality of conductors. A receiver receives a plurality of second signals representative of the first signal at a second end of the plurality of conductors, respectively, and outputs data representative of the plurality of second signals. A processor receives the data representative of the plurality of second signals, determines a common mode insertion loss for the cable or cabling installation based on the plurality of second signals, determines, based on the common mode insertion loss, whether the shield is continuous or discontinuous and outputs data representative of whether the shield is continuous or discontinuous.

Abstract: Systems, cameras, and software for performing optical gas imaging using thermal imaging. Processors are programmed with instructions for a method of detecting gas that includes creating a filtered background image, a filtered foreground image, and optical gas image data, and generating a display image. The filtered background image and filtered foreground images may be created by combining infrared image data from a plurality of images captured by an infrared camera module using filtering processes. The optical gas image data may be created by comparing the filtered background image and the filtered foreground image. An image may be generated that includes the optical gas image data for presentation on a display.

Abstract: Infrared cameras can include an infrared sensor and an infrared lens assembly defining an optical axis. A camera can include an inner gear engaging the infrared lens assembly and a focus ring that engages the inner gear. The inner gear can engage the focus ring and the infrared lens assembly such that rotation of the focus ring about its central axis can cause the rotation of the infrared lens assembly about its optical axis, which may be offset from the central axis of the focus ring. The camera can include a sensor can threadably engaging the infrared lens assembly and fixed relative to the infrared sensor such that rotation of the infrared lens assembly causes the infrared lens assembly to move relative to the infrared sensor. The sensor can can support other components such as a visible light lens assembly or a laser within a perimeter of the focus ring.

Abstract: A method and computer program product for determining whether an object of interest can have its temperature measurement calculated by a thermal imaging camera. To do this, the measurement IFOV is converted into linear units. The measurement IFOV may be displayed on the display of the camera as a graphical indicator (100, 100?, 100?, 100??) or a value. An object of interest can be registered with the graphical indicator (100, 100?, 100?, 100??) or its dimension compared with the measurement IFOV and then it is determined whether the temperature measurement of the object can be acceptably calculated. Alternately, data obtained by a matrix of pixel elements may be analyzed to determine whether an accurate temperature can be calculated.
