Patent number: 11099075Abstract: Systems and methods directed toward acoustic analysis can include an acoustic sensor array comprising a plurality of acoustic sensor elements, an electromagnetic imaging tool, a distance measuring tool, and a processor in communication with the acoustic sensor array, the electromagnetic imaging tool, and the distance measuring tool. The processor can be configured to generate acoustic image data based on acoustic signals received from the acoustic sensor array and distance information received from the distance measuring tool. The processor can combine the generated acoustic image data and received electromagnetic image data from the electromagnetic imaging tool to create a display image including acoustic image data and electromagnetic image data. The processor can be configured to correct a parallax error between the electromagnetic image data and the acoustic image data based on the received distance information.Type: GrantFiled: November 2, 2017Date of Patent: August 24, 2021Assignee: Fluke CorporationInventor: Michael D.

Patent number: 10965889Abstract: A method and computer program product for determining whether an object of interest can have its temperature measurement calculated by a thermal imaging camera. To do this, the measurement IFOV is converted into linear units. The measurement IFOV may be displayed on the display of the camera as a graphical indicator (100, 100?, 100?, 100??) or a value. An object of interest can be registered with the graphical indicator (100, 100?, 100?, 100??) or its dimension compared with the measurement IFOV and then it is determined whether the temperature measurement of the object can be acceptably calculated. Alternately, data obtained by a matrix of pixel elements may be analyzed to determine whether an accurate temperature can be calculated.Type: GrantFiled: June 20, 2012Date of Patent: March 30, 2021Assignee: Fluke CorporationInventors: Michael D.

Publication number: 20200258213Abstract: Systems and methods can be used for analyzing image data to determine an amount of vibration and/or misalignment in an object under analysis. In some instances, as operating equipment heats up during operation, temperature changes of various portions of the operating equipment leads to changes in dimensions of such portions, leading to misalignment. Multiple sets of data representative of the operating equipment in multiple operating conditions can be used to determine an amount of misalignment due to thermal offsets. Hot and cold temperatures of the equipment can be used to calculate thermal growth of various portions of the equipment, which can be used to determine an amount a misalignment due to thermal offsets. Additionally or alternatively, image data representing the equipment can be used to observe changes in alignment between states.Type: ApplicationFiled: February 28, 2020Publication date: August 13, 2020Inventors: Michael D.

Patent number: 10337962Abstract: A smart phone user captures video and still images of a motor and makes a sound recording of his observations. The images and recordings are tagged with a date/time stamp, a serial number, bar code, matrix code, RFID code, or geolocation and sent wirelessly to an infrared camera. The infrared camera has a collocation application that reads the tag and creates a folder which holds the infrared image and the auxiliary information from the smartphone related to an asset. The collocation program also adds icons to the infrared image. By operating the user interface (not shown) of the infrared camera, the user may select an icon to view the images and listen to the sound recording.Type: GrantFiled: March 14, 2014Date of Patent: July 2, 2019Assignee: Fluke CorporationInventors: Michael D.

Patent number: 10120021Abstract: Systems and methods detect abnormal conditions in electrical circuits by providing thermal imaging combined with non-contact measurements of current and voltage. Such systems may be implemented in a single test device, or in wired combinations, or in wireless communication implementations with multiple test devices and/or accessories, or in combination with one or more additional devices, such as a mobile phone, tablet, personal computer (PC), cloud-based server, etc. A thermal imaging tool that includes an infrared sensor may first discover and image one or more thermal anomalies in an object, such as an electrical circuit. One or more non-contact current or voltage sensors may be used to measure current and/or voltage, which allows for determination of the power loss at the measured location. The power loss may be used to determine an estimation of the abnormal resistive power losses in a circuit, as well as the costs associated therewith.Type: GrantFiled: June 16, 2017Date of Patent: November 6, 2018Assignee: Fluke CorporationInventors: Luis R.

Publication number: 20160131607Abstract: Systems can include a resistance testing device configured to generate resistance data regarding the insulation resistance of equipment under test and a temperature sensing device configured to generate temperature data regarding the temperature of the equipment under test. The system can include a processor configured to receive the resistance data and the temperature data. Based on the received data, the processor can determine normalized resistance data accounting for temperature effects on the measured resistance. Normalized resistance data can indicate a predicted value for the insulation resistance measurement had the measurement been performed at a reference temperature. Thus, insulation resistance values normalized to a common temperature can be more accurately and meaningfully analyzed and trended over time.Type: ApplicationFiled: September 16, 2015Publication date: May 12, 2016Inventors: Luis R.
