  • Patent number: 10585133
    Abstract: A single-ended traveling wave fault location estimation is calculated using this disclosure, and a confidence level is determined based on available independent fault location estimations. Hypothesis are calculated based on traveling wave times and values, wherein the values indicate a polarity that is the same as the first received traveling wave. Hypothesis are then compared against results of other fault location estimations, and confidence levels assigned accordingly. The fault location is then calculated and displayed based on the hypothesis and confidence levels.

  • Patent number: 10585203
    Abstract: A radio frequency (RF) imaging device comprises a position sensor, an optical sensor, a processor, and an output. The position sensor determines a position of the RF imaging device relative to a surface. The optical sensor captures optical image data representing an optical image of an area of the surface. The optical image data is associated with position data representing a position relative to the surface derived from the determined position of the RF imaging device. The derived position data corresponds to the area of the surface imaged by the optical sensor. The processor produces a composite image in which one or more portions of the optical image data are simultaneously viewable with RF image data representing an RF image of a space behind the surface at the same position as the optical image data. The output displays the composite image. The output may be a projector.

  • Patent number: 10578649
    Abstract: Vertical probe heads having a space transformer laterally tiled into several sections are provided. This change relative to conventional approaches improves manufacturing yield. These probe heads can include metal ground planes, and in embodiments where the ground planes are provided as separate metal plates parallel to the guide plates, the metal plates can also be laterally tiled into several sections. Such tiling of metal plates improves manufacturing yield and alleviates thermal mismatch issues. Probes are not mechanically connected to the space transformer, which facilitates replacement of individual probes of an array.

  • Patent number: 10571591
    Abstract: A radio frequency (RF) imaging device comprises an optical position sensor, an RF sensor assembly, a processor, and a memory. The optical position sensor captures an optical image of a field of view and outputs data representing the optical image. The RF sensor assembly is disposed at a first position and receives an RF signal for capturing an RF image of a portion of a space disposed behind a surface at the first position and outputs data representing the RF signal. The processor receives the data representing the optical image and the RF signal, and determines that an optical signature of a reference marker is present in the optical image. If the optical signature is present in the optical image, the processor defines the first position of the RF assembly as a reference position. The memory stores the data representing the RF signal in association with the reference position.
