Patent number: 11651670Abstract: A method of detecting a flame in an image comprising the step of acquiring a series of infrared images from an infrared imager. Image flow vectors are calculated for each of the series of infrared images and stored in a corresponding 2D vector array. At least one 3D image flow data set is generated from the corresponding 2D vector arrays. A 2D pixel intensity array is generated for each of the series of infrared images. A 3D pixel intensity data set is generated from the 2D pixel intensity arrays. A Fourier Transform and infrared metrics are calculated. The infrared metrics are compared to an infrared threshold criteria. A corresponding 2D threshold array for each of the series of infrared images is generated. A 3D threshold data set is generated from the 2D threshold arrays. A flame status is determined based on the 3D threshold data set.Type: GrantFiled: July 9, 2020Date of Patent: May 16, 2023Assignee: CARRIER CORPORATIONInventor: Jamie Rhead

Patent number: 10585203Abstract: 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.Type: GrantFiled: April 28, 2016Date of Patent: March 10, 2020Assignee: Fluke CorporationInventors: Jamie Rhead, Paul H.

Patent number: 10571591Abstract: 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.Type: GrantFiled: April 28, 2016Date of Patent: February 25, 2020Assignee: Fluke CorporationInventors: Jamie Rhead, Paul H.
