Abstract: Acoustic imaging systems can include an acoustic sensing array, an electromagnetic imaging tool, a display, and an audio device. A processor can receive data from the acoustic sensor array and the electromagnetic imaging tool to generate a display image combining acoustic image data and electromagnetic image data. Systems can include an audio device that receives an audio output from the processor and outputs audio feedback signals to a user. The audio feedback signals can represent acoustic signals from an acoustic scene. Systems can provide a display image to a user including acoustic image data, and a user can select an acoustic signal for which to provide a corresponding audio output to an audio device. Audio outputs and display images can change dynamically in response to a change in pointing of the acoustic sensing array, such as by changing a stereo audio output.

Abstract: A system for testing an optical fiber includes an optical source apparatus and an optical image sensor apparatus. The optical source apparatus includes a fiber optic connector that connects to a first end of the fiber, and a light emitting device which emits light into the first end of the fiber. The optical image sensor apparatus includes a fiber optic connector that connects to a second end of the fiber, an image sensor that receives light output from the second end of the fiber and generates corresponding image data, a lens array in an optical path between the fiber optic connector and the image sensor, and a processor coupled to the image sensor. The processor, in operation, determines a set of two-dimensional positions based on the image data output from the image sensor, and determines a test result based on the set of two-dimensional positions.

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.

Abstract: Accessories are removably received by a non-contact electrical detector for measuring an electrical characteristic without galvanic contact between the accessory and a non-contact sensor in the non-contact electrical detector. In some embodiments, an accessory is positioned in a gap between first and second extensions of the non-contact electrical detector. In some embodiments, an accessory includes first and second recesses on opposite sides of the accessory. First and second clamp arms of a non-contact electrical detector are inserted within the first and second recesses to removably hold the accessory. An external conductive prong of the accessory is electrically coupled, or is selectively electrically coupleable, with an internal conductive prong of the accessory. The external conductive prong is configured to be inserted into a receptacle of an electrical outlet. In use, the accessory positions the internal conductive prong within a sensing area of the non-contact electrical sensor of the non-contact electrical detector.

Abstract: A system for determining a signature frequency of a photonic device includes a reference cell that receives a first light beam of a plurality of light beams. Based on a predetermined characteristic of the reference cell, the reference cell produces a first identifiable output indicative of a reference frequency in response to light in the first light beam having a particular frequency. A photonic device receives a second light beam of the plurality of light beams, and produces a second identifiable output in response to light in the second light beam having a frequency at the signature frequency. A computing device uses electrical signals representative of the first and second identifiable outputs to determine the signature frequency of the photonic device. A light source may emit a light beam having a controlled change of frequency and an optical splitter splits the light beam to produce the plurality of light beams.

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.
