  • Patent number: 10809598
    Abstract: An add-on lens assembly supporting an add-on lens for a camera includes a locking mechanism actuatable by the user in order to increase the attachment force between the lens and the camera. The add-on lens assembly may include a rotatable lock ring having a cam pin that navigates along a surface of a cam such that when the lock ring is rotated, the cam pin causes the cam to translate axially. Axial translation of the cam may compress a spring within the assembly and increase the attachment force between the lens assembly and the camera. The increased force between the add-on lens assembly and the camera may provide additional support for large or heavy assemblies.

  • Patent number: 10802072
    Abstract: Systems and methods for measuring direct current (DC) voltage of an insulated conductor (e.g., insulated wire) are provided, without requiring a galvanic connection between the conductor and a test electrode or probe. A non-contact DC voltage measurement device may include a conductive sensor that is mechanically oscillated. The insulated conductor under test serves as a first conductive element or electrode of a coupling capacitor, and the vibrating conductive sensor serves as a second conductive element or electrode of the coupling capacitor. The oscillation of the conductive sensor provides the coupling capacitor with a time-varying capacitance value. The measurement device detects current flowing through the coupling capacitor, and determines the DC voltage in the insulated conductor using the detected current and the time-varying capacitance. The determined DC voltage may be output to a display or transmitted to an external system via a wired or wireless connection.

  • Patent number: 10788401
    Abstract: A method, system, and computer-readable medium for sharing measurement data with a remote device includes establishing, by a mobile computing device at an equipment site, a first communication connection with a measurement device that is configured to measure data with respect to equipment at the equipment site. The mobile computing device receives measurement data by way of the first communication connection. While remaining at the equipment site, the mobile computing device receives a request to share the measurement data with a selected contact via a remote device. In response, a second communication connection is established with the remote device, the measurement data to be shared is identified, and the identified measurement data is communicated to the remote device for review by the selected contact. Prior to establishing a communication connection with the remote device, permission to communicate the measurement data to the selected contact may be obtained from a gatekeeper.

  • Patent number: 10782192
    Abstract: A calibration device includes a tank, a propeller disposed within the tank, a motor coupled to the propeller, a processor coupled to the motor, and a memory. The memory stores instructions that, when executed by the processor, cause the motor to rotate at a specified speed based on input an indication of an actual speed of the motor. The memory may store instructions that cause the device to dynamically change the speed of the motor based on the viscosity of a fluid in the tank, which changes as the temperature of the fluid changes. In addition, the memory may store instructions that cause the device to determine whether the fluid in the tank is deteriorated, and to provide an operator alert in response to determining that the fluid is deteriorated.

  • Patent number: 10775409
    Abstract: Systems and methods for measuring electrical parameters (e.g., voltage, current, power) in an insulated or blank uninsulated conductor (e.g., insulated wire) without requiring a galvanic connection between the conductor and a clamp probe. A clamp probe may include a normally closed, spring loaded jaw having a flexible strap therein that includes one or more non-contact sensors. The jaw may also include a Rogowski coil to enable non-contact current measurements. A user may compress handles of the clamp probe to open its jaw. In the open position, the user may position the jaw around the conductor under test and release the handles. The jaw then closes and tightens the flexible strap around the insulated conductor such that the one or more non-contact sensors are positioned adjacent the insulated conductor to obtain an accurate measurement of an electrical parameter of the insulated conductor.

  • Patent number: 10726559
    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: 10725095
    Abstract: A system for measuring a device under test (DUT) includes a computing device and a measurement device that measures an electrical or physical parameter of the DUT. The computing device receives and stores measurement data in a DUT record associated with the DUT. The computing device further obtains a first image of the DUT, displays the first image as a reference image with a first reference frame, receives a live image of the DUT from an image sensor, and displays the live image with a second reference frame that corresponds to the first reference frame. A cursor on the live image moves according to movement of the image sensor relative to the DUT. A second image of the DUT is obtained, wherein the second image is substantially aligned with the reference image based on an alignment of the cursor with the second reference frame. The second image is stored in the DUT record.

  • Patent number: 10719698
    Abstract: Systems and methods are directed toward occupancy detection in a predefined space including one or more sub-zones. Occupancy of the predefined space can be determined by determining the occupancy of an outer zone comprising the predefined space, and determining the occupancy of individual sub-zones to the outer zone. Occupancy values of the individual sub-zones can be rescaled such that the sum of the individual sub-zones occupancies sum to the already determined outer zone occupancy. The occupancy of the predefined space then may be determined using the rescaled occupancies of the various sub-zones included in the predefined space. Such processes can be repeated for individual sub-zones, which may be treated as a separate outer zone including one or more sub-zones.
