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.

RF in-wall image registration using optically-sensed markers

A radio frequency (RF) imaging device comprises a position sensor, an RF sensor assembly, an optical sensor, a processor, and a memory. The position sensor determines a position of the RF imaging device relative to a surface. The RF sensor assembly captures RF image data representing an RF image of a portion of a space behind the surface at the determined position. The optical sensor captures optical image data representing an optical image of the surface at the determined position. The processor produces a composite image in which at least one or more portions of the RF image and one or more portions of the optical image that correspond to the same position relative to the surface are simultaneously viewable. The RF image data and the optical image data are stored in the memory in association with position data derived from the determined position of the RF imaging device.

Optical image capture with position registration and RF in-wall composite image

A method and apparatus for blending and display of radio frequency in-wall imagery are provided. In the method and apparatus, an RF sensor assembly receives an RF signal for capturing an RF image of one or more objects including an electricity-bearing object disposed in a space behind a surface, a voltage sensor detects a presence of the electricity-bearing object disposed in the space behind the surface and a processor determines the RF image based on the data representing the RF signal, identifies a position of the electricity-bearing object in the RF image based on the data indicating the presence of the electricity-bearing object and a relative position of the sensory field to the RF sensor assembly and generates, based on the RF image, a composite image in which the electricity-bearing object is marked.

Blending and display of RF in wall imagery with data from other sensors

A calibrator has profiles for holding locators for items in a tree-like database of smart device that monitors a process. The calibrator is connected to the smart device and obtains tag and other identity information to find the profile for the smart device. When a profile is located, the calibrator displays a list of calibration setup items and favorite items and loads the items on the list into the calibrator as default inputs or settings.

Profiles for streamlining calibration test

A communicator has profiles for holding locators for items in a tree-like database for a smart device that monitors a process. The communicator is connected to the smart device and obtains tag and other identity information to find the profile for the smart device. When a profile is located, the communicator displays a list of configuration items and favorite items and loads the items on the list into the communicator as default inputs or settings.

A handheld wireless transmitter network analysis tool has a transceiver for detecting wireless signals from a transceiver of a smart device used in an automated process control. The tool has a processor with program modules for analyzing the spectrum of received wireless signals and noise. Another memory module includes a device description protocol program for reading tag and primary variable data carried by the wireless signals from smart device. The network tool displays the frequency and spectrum of the wireless signal from smart device, the tag and primary variables for device, the signal to noise ratio and the possible identity of the sources of noise.
